In at least one embodiment, a brake assembly is provided as set out in appended independent claim <NUM>.

Referring to <FIG>, an example of a brake assembly <NUM> is shown. The brake assembly <NUM> may be provided as part of a vehicle, such as a motor vehicle like a truck, bus, farm equipment, military transport or weaponry vehicle, or cargo loading equipment for land, air, or marine vessels. The brake assembly <NUM> may be configured as a disc brake. In at least one configuration, the brake assembly <NUM> may include a brake carrier <NUM>, a brake caliper <NUM>, a pair of brake pad assemblies <NUM>, and optionally a retainer bracket <NUM>. Referring primarily to <FIG>, the brake assembly <NUM> may also include at least one guide pin assembly <NUM>.

Referring to <FIG> and <FIG>, the brake carrier <NUM> may be fixedly mountable to the vehicle. For example, the brake carrier <NUM> may be directly or indirectly mounted to an axle assembly or a steering knuckle. The brake carrier <NUM> may receive and support the brake pad assemblies <NUM> in a manner that permits the brake pad assemblies <NUM> to move toward and away from a brake rotor <NUM> while inhibiting rotation of the brake pad assemblies <NUM>. The brake carrier <NUM> may include a rotor opening that may receive a brake rotor <NUM> that may be rotatable about a brake rotor axis <NUM>. As such, the brake carrier <NUM> may straddle the brake rotor <NUM> and help position the brake pad assemblies <NUM> on opposite sides of the brake rotor <NUM>. In addition, the brake carrier <NUM> may include one or more fastener holes <NUM> that may facilitate mounting of a corresponding guide pin assembly <NUM>.

Referring to <FIG>, a fastener hole <NUM> may have any suitable configuration. For instance, a fastener hole <NUM> may be threaded and may be configured as a through hole.

Referring to <FIG> and <FIG>, the brake caliper <NUM> may receive various components of the brake assembly <NUM>. In addition, the brake caliper <NUM> may facilitate positioning of the brake pad assemblies <NUM> with respect to the brake rotor <NUM> to facilitate braking of the vehicle. In at least one configuration, the brake caliper <NUM> may include a caliper housing <NUM> and a caliper bridge <NUM>.

Referring to <FIG>, <FIG> and <FIG>, the caliper housing <NUM> may be moveably disposed on the brake carrier <NUM>. For example, the caliper housing <NUM> may be slidably disposed on a pair of guide pin assemblies <NUM> that may be fixedly disposed on the brake carrier <NUM>. The caliper housing <NUM> may facilitate mounting of the brake actuator and may define a cavity that may receive or partially receive various components that facilitate movement of the brake pad assemblies <NUM>, such as an operating shaft, yoke, tappet, piston, and wear adjuster mechanism. Examples of such components are described in <CIT>. It is further noted that the present invention is not limited to configurations as described in <CIT>. In at least one configuration, the caliper housing <NUM> may define one or more bores <NUM>.

Referring to <FIG> and <FIG>, a bore <NUM> may be configured to receive a corresponding guide pin assembly <NUM>. A pair of bores <NUM> may be provided that may be disposed proximate opposite lateral sides of the brake caliper <NUM>. In at least one configuration, each bore <NUM> may extend along an axis <NUM> and may be configured as a through hole. The axis <NUM> may extend parallel or substantially parallel to the brake rotor axis <NUM>. A bore <NUM> may have a cylindrical configuration in which the bore <NUM> may be defined by a bore surface <NUM>. The bore surface <NUM> may extend around the axis <NUM>. The bore surface <NUM> may be radially disposed with respect to the axis <NUM>.

A cap <NUM> may be provided to cover the end of the bore <NUM> that faces away from the brake carrier <NUM>. In at least one configuration, the cap <NUM> may be received in the bore <NUM> and may partially receive the guide pin assembly <NUM>.

A flexible boot <NUM> may extend between the brake carrier <NUM> and the brake caliper <NUM> or between the guide pin assembly <NUM> and the brake caliper <NUM>. The flexible boot <NUM> may flex response to movement of the brake caliper <NUM>. For instance, the flexible boot <NUM> may expand or unfold when the brake caliper <NUM> moves in a first direction with respect to the brake carrier <NUM> and may contract or fold when the brake caliper <NUM> moves in a second direction with respect to the brake carrier <NUM>.

Referring to <FIG> and <FIG>, the caliper bridge <NUM> may extend from the caliper housing <NUM>. The caliper bridge <NUM> may be integrally formed with the caliper housing <NUM> or may be fixedly disposed on the caliper housing <NUM>. For example, the caliper bridge <NUM> may be provided as a separate component that may be coupled to the caliper housing <NUM> with one or more fasteners, such as bolts. In at least one configuration, the caliper bridge <NUM> may cooperate with the caliper housing <NUM> to at least partially define an opening that may facilitate insertion and removal of the brake pad assemblies <NUM>.

A pair of brake pad assemblies <NUM> may be received in and may be supported by the brake carrier <NUM>. The brake pad assemblies <NUM> may be disposed on opposite sides of the brake rotor <NUM> and may be engageable with the brake rotor <NUM> to slow rotation of the brake rotor <NUM> and an associated wheel about the brake rotor axis <NUM>. One brake pad assembly <NUM> may be positioned between the caliper housing <NUM> and the brake rotor <NUM> and may be referred to as an inboard brake pad assembly <NUM>. The inboard brake pad assembly <NUM> is located to the right of the brake rotor <NUM> from the perspective shown in <FIG>. The other brake pad assembly <NUM> may be positioned on the opposite side of the brake rotor <NUM> between the caliper bridge <NUM> and the brake rotor <NUM> and may be referred to as an outboard brake pad assembly <NUM>. The outboard brake pad assembly <NUM> is located to the left of the brake rotor <NUM> from the perspective shown in <FIG>. Each brake pad assembly <NUM> may include a backplate <NUM> and friction material <NUM>.

The backplate <NUM> may be a structural member of a brake pad assembly <NUM>. The backplate <NUM> may be configured as a generally flat plate and may be made of any suitable material, such as metal or a metal alloy. In at least one configuration, a side of the backplate <NUM> of the inboard brake pad assembly <NUM> that faces away from the friction material <NUM> may engage or contact a tappet that may be extendable from the cavity of the caliper housing <NUM> to actuate the inboard brake pad assembly <NUM> into engagement with the brake rotor <NUM>. A side of the backplate <NUM> of the outboard brake pad assembly <NUM> that faces away from its friction material <NUM> may engage or contact the caliper bridge <NUM>.

The friction material <NUM> may be disposed on a side of the backplate <NUM> that may face toward the brake rotor <NUM>. The friction material <NUM> may contact the brake rotor <NUM> during vehicle braking.

Referring to <FIG> and <FIG>, the retainer bracket <NUM> may be removably mounted to the brake caliper <NUM>. For example, the retainer bracket <NUM> may extend across the brake pad assemblies <NUM> and the opening in the brake caliper <NUM> to help retain the brake pad assemblies <NUM> in the brake carrier <NUM> when the retainer bracket <NUM> is secured to the brake caliper <NUM>. The retainer bracket <NUM> may be detached from or removed from the brake caliper <NUM> to permit removal of the brake pad assemblies <NUM> or installation of the brake pad assemblies <NUM> via the opening.

Referring to <FIG> and <FIG>, the guide pin assembly <NUM> may slidably couple the brake caliper <NUM> to the brake carrier <NUM> such that the brake caliper <NUM> may slide along the guide pin assembly <NUM>. In at least one configuration, the guide pin assembly <NUM> may include a fastener <NUM>, a sleeve <NUM>, at least one bushing <NUM>, and at least one resilient member <NUM>.

Referring primarily to <FIG> and <FIG>, the fastener <NUM> may fixedly couple the sleeve <NUM> to the brake carrier <NUM>. The fastener <NUM> may have any suitable configuration. For instance, the fastener <NUM> may be configured as a bolt, such as a carriage bolt, that may be received in the fastener hole <NUM> of the brake carrier <NUM>. The fastener <NUM> may be partially received in the bore <NUM> of the caliper housing <NUM> and may extend along or around the axis <NUM>. It is noted that in <FIG>, <FIG>, <FIG> and <FIG> that the fastener <NUM> has not been sectioned for clarity but is in the section plane.

The sleeve <NUM> may receive the fastener <NUM>. For instance, the sleeve <NUM> may be configured as a hollow tube that may receive the fastener <NUM> and that may be at least partially received in the bore <NUM> of the caliper housing <NUM>. The hollow portion of the sleeve <NUM> that may receive the fastener <NUM> may be sized slightly larger than the fastener <NUM> so as to permit insertion and rotation of the fastener <NUM> for assembly purposes but may otherwise generally center the sleeve <NUM> about the axis <NUM>. The sleeve <NUM> may be fixedly positioned or stationary with respect to the brake carrier <NUM>. The sleeve <NUM> may extend from and may engage or contact the brake carrier <NUM>. Alternatively, the sleeve <NUM> may be separated from the brake carrier <NUM> by an intervening component.

In at least one configuration, the sleeve <NUM> may have an exterior surface <NUM> that may face away from the axis <NUM>. The sleeve <NUM> may also include a recess <NUM>, one or more grooves <NUM>, or both.

The exterior surface <NUM> may be at least partially received in the bore <NUM> of the caliper housing <NUM>. The exterior surface <NUM> may be an outside circumferential surface of the sleeve <NUM> and may be spaced apart from the bore surface <NUM>. The exterior surface <NUM> may extend from the recess <NUM>.

The recess <NUM>, if provided, may extend toward the axis <NUM> from the exterior surface <NUM>. As such, the recess <NUM> to may have a smaller diameter than the exterior surface <NUM>. The recess <NUM> may or may not receive a bushing <NUM> as will be discussed in more detail below. In at least one configuration and as is best shown with reference to <FIG>, the recess <NUM> may be defined by a recess bottom surface <NUM>, a first recess end surface <NUM>, and/or a second recess end surface <NUM>.

The recess bottom surface <NUM> may be disposed at the bottom of the recess <NUM>. The recess bottom surface <NUM> may be disposed closer to the axis <NUM> than the exterior surface <NUM>. In at least one configuration, the recess bottom surface <NUM> may extend substantially parallel to the axis <NUM>, the bore surface <NUM>, the exterior surface <NUM>, or combinations thereof.

The first recess end surface <NUM> may extend away from the axis <NUM> from an end of the recess bottom surface <NUM>. For instance, the first recess end surface <NUM> may extend from a first end of the recess bottom surface <NUM> to the exterior surface <NUM>.

The second recess end surface <NUM> may extend away from the axis <NUM> from a second end of the recess bottom surface <NUM> that may be disposed opposite the first end. As such, the second recess end surface <NUM> may be disposed opposite the first recess end surface <NUM>. It is also contemplated that the first recess end surface <NUM> or the second recess end surface <NUM> may be omitted, in which case the recess <NUM> may extend to an end of the sleeve <NUM> and may not extend to the exterior surface <NUM>.

One or more grooves <NUM> may be provided with the sleeve <NUM>. A groove <NUM> may partially receive at least one resilient member <NUM>. If provided, a groove <NUM> may be provided in addition to a recess <NUM> or in lieu of a recess <NUM>. In the configuration shown, four grooves <NUM> are illustrated that are provided in the recess <NUM>; however, it is contemplated that a greater or lesser number of grooves <NUM> may be provided. A groove <NUM> may extend from the exterior surface <NUM> toward the axis <NUM> if the recess <NUM> is not provided. A groove <NUM> may extend from the recess bottom surface <NUM> toward the axis <NUM> if the recess <NUM> is provided. In such a configuration, the groove <NUM> may have a smaller diameter than the recess bottom surface <NUM>. The grooves <NUM> may be spaced apart from each other when multiple grooves <NUM> are provided.

One or more bushings <NUM> may be received in the bore <NUM> of the brake caliper <NUM>. A bushing <NUM> may extend around and may receive the sleeve <NUM>. A bushing <NUM> may be spaced apart from the sleeve <NUM>. In <FIG> and <FIG>, a pair of bushings <NUM> are illustrated; however, it is contemplated that a greater or lesser number of bushings <NUM> may be provided. For instance, a single bushing <NUM> may be provided or more than two bushings <NUM> may be provided. For convenience in reference, the bushing <NUM> that is located furthest to the left from the perspective shown may be referred to as an outboard bushing while the bushing <NUM> that is located furthest to the right from the perspective shown may be referred to as an inboard bushing. In at least one configuration, the bushings <NUM> may be spaced apart from each other.

Referring primarily to <FIG> and <FIG>, a bushing <NUM> may have any suitable configuration. For instance, a bushing <NUM> may be configured as a hollow cylinder and may include a first end <NUM>, a second end <NUM>, an outer surface <NUM>, and an inner surface <NUM>. Optionally, bushing <NUM> may be provided with a slit <NUM> that may extend from the first end <NUM> to the second end <NUM>. The slit <NUM> may split or separate the bushing <NUM> so that the bushing <NUM> may be expanded or contracted with respect to the axis <NUM> to accommodate manufacturing tolerances.

The first end <NUM> and the second end <NUM> may be spaced apart from each other and may be positioned at opposite ends of the bushing <NUM>. The first end <NUM> may face toward the brake carrier <NUM>. The second end <NUM> may face away from the brake carrier <NUM>.

The outer surface <NUM> may face away from the axis <NUM> and may extend from the first end <NUM> to the second end <NUM>. The outer surface <NUM> may engage or contact the bore surface <NUM> of the bore <NUM> in the caliper housing <NUM>. The brake caliper <NUM> and more specifically the caliper housing <NUM> may be slidable along the outer surface <NUM>.

The inner surface <NUM> may be disposed opposite the outer surface <NUM>. As such, the inner surface <NUM> may face toward the axis <NUM>, the sleeve <NUM>, and a resilient member <NUM>. The inner surface <NUM> and may extend from the first end <NUM> to the second end <NUM>. The inner surface <NUM> may be spaced apart from the sleeve <NUM> but may engage or contact a bushing <NUM>.

A bushing <NUM> may or may not be partially received in the recess <NUM> of the sleeve <NUM>.

In the configuration shown in <FIG>, the bushings <NUM> are not received in the recess <NUM>. In such a configuration, the inner surface <NUM> of the bushing <NUM> may have a larger diameter than the recess bottom surface <NUM>, the grooves <NUM>, or both. The inner surface <NUM> may have a larger diameter than the exterior surface <NUM> of the sleeve <NUM> or the same diameter as the exterior surface <NUM> of the sleeve <NUM>.

In the configuration shown in <FIG>, the bushings <NUM> extend into and are partially received in the recess <NUM>. In such a configuration, the inner surface <NUM> of the bushing <NUM> may have a smaller diameter than the exterior surface <NUM> of the sleeve <NUM>. Moreover, the inner surface <NUM> may have a larger diameter than the recess bottom surface <NUM>, the grooves <NUM>, or both. The first end <NUM>, a second end <NUM>, or both may be engageable with the sleeve <NUM> to limit or inhibit axial movement of a bushing <NUM>. For instance, the first end <NUM> of a bushing <NUM> may be engageable with the first recess end surface <NUM> to inhibit axial movement of a bushing <NUM>, such as the outboard bushing, to the left from the perspective shown. The second end <NUM> of a bushing <NUM> may face toward the second recess end surface <NUM> and may be engageable with the second recess end surface <NUM> to inhibit axial movement of a bushing <NUM>, such as the inboard bushing, to the right from the perspective shown.

Referring to <FIG>, at least one resilient member <NUM> may be received in a bushing <NUM>. A resilient member <NUM> may extend between the sleeve <NUM> and a bushing <NUM>. For instance, a resilient member <NUM> may extend from the inner surface <NUM> of the bushing <NUM> to the sleeve <NUM>. A resilient member <NUM> may be received in the recess <NUM> in the sleeve <NUM>, a groove <NUM> in the sleeve <NUM>, or both. It is also contemplated that a resilient member <NUM> may extend to the exterior surface <NUM>. The resilient member <NUM> may have any suitable configuration. For instance, the resilient member <NUM> may extend continuously around the sleeve <NUM> and may be configured as an O-ring, a hollow tube or tubular structure, or the like. In the configuration shown, two resilient members <NUM> are provided inside each bushing <NUM>; however, it is contemplated that a greater or lesser number of resilient members <NUM> may be provided. Resilient members <NUM> may be spaced apart from each other as shown or may be disposed adjacent to each other such that one resilient member <NUM> may engage or contact one or more other resilient members <NUM>.

A resilient member <NUM> may be made of any suitable material. For instance, a resilient member <NUM> may be made of an elastomeric material like rubber or a polymer that may display rubber-like elasticity. As such, the resilient member <NUM> may absorb energy (e.g., store potential energy) when it is loaded and elastically deformed and may release energy when unloaded. A resilient member <NUM> may be compressed in a radial direction (e.g., along a radius that may extend perpendicular to the axis <NUM>) when received inside a bushing <NUM>. As such, the resilient member <NUM> may push or urge the bushing <NUM> away from the axis <NUM> and toward the bore surface <NUM>.

The friction or "grip" between the resilient member <NUM> and the bushing <NUM> may be a function of the material properties of the resilient member <NUM>, the material properties of the bushing <NUM>, and the amount of compression of the resilient member <NUM>. This friction or grip may also allow the resilient member <NUM> to be deformed when the brake caliper <NUM> moves axially with respect to the sleeve <NUM>. For instance, the brake caliper <NUM> may be slidable along or parallel to the axis <NUM> in a first direction and in a second direction that may be disposed opposite the first direction. The first direction may extend to the right from the perspective shown in <FIG>, <FIG>, <FIG> and <FIG>. The second direction may extend to the left from the perspective shown.

The brake caliper <NUM> may move in the first direction with respect to the brake carrier <NUM> when braking or a braking force is applied. For example, the inboard brake pad assembly <NUM> may be moved from a retracted position in which the inboard brake pad assembly <NUM> may be spaced apart from the brake rotor <NUM> as shown in <FIG> into contact with the brake rotor <NUM> as shown in <FIG>. Once the inboard brake pad assembly <NUM> contacts the brake rotor <NUM>, a reaction force may then move the brake caliper <NUM> in the first direction with respect to the brake carrier <NUM> to actuate the outboard brake pad assembly <NUM> into engagement with the opposite side of the brake rotor <NUM> as shown in <FIG> to help slow rotation of the brake rotor <NUM> and an associated vehicle wheel. The bore surface <NUM> of the caliper housing <NUM> may slide along the outer surface <NUM> of the bushing <NUM> when the caliper housing <NUM> moves in the first direction. In addition, the resilient member <NUM> may distort (e.g., twist, rotate, bend, flex, etc.) in the first direction when the caliper housing <NUM> moves in the first direction, thereby storing potential energy in the resilient member <NUM> that may have an axial force vector component. Distortion of the resilient member <NUM> may allow the bushing <NUM> to move in the first direction when the caliper housing <NUM> moves in the first direction. As such, the bushing <NUM> may move with respect to the sleeve <NUM> when the brake caliper <NUM> slides along a bushing <NUM>. The bushing <NUM> may move a shorter distance in the first direction than the caliper housing <NUM> moves in the first direction when braking is applied due to sliding of the caliper housing <NUM> along the bushing <NUM>.

The brake caliper <NUM> may be slidable in the second direction under the biasing force exerted by the resilient member <NUM>. Movement may occur in the second direction from the positioning shown in <FIG> back toward the positioning shown in <FIG> when braking force is subsequently released. For instance, retracting the inboard brake pad assembly <NUM> may disengage and separate the inboard brake pad assembly <NUM> from the brake rotor <NUM>. The resilient member <NUM> may then be allowed to release its potential energy and bias or urge the brake caliper <NUM> to slide in the second direction (to the left from the perspective and positioning shown in <FIG> back to or toward the positioning shown in <FIG>). The outboard brake pad assembly <NUM> may be movable away from the brake rotor <NUM> when the brake carrier <NUM> moves in the second direction. More specifically, sliding the brake caliper <NUM> in the second direction may increase the axial distance between the caliper bridge <NUM> and the brake rotor <NUM> and thus allow the outboard brake pad assembly <NUM> to retract, disengage and separate from the brake rotor <NUM>. Retraction of the inboard brake pad assembly <NUM>, the outboard brake pad assembly <NUM>, or both may optionally be aided by one or more retraction springs, such as is disclosed in <CIT>. Release of potential energy from the resilient member <NUM> may allow the resilient member <NUM> or resilient members <NUM> to return or move with respect to the sleeve <NUM> back to or toward its/their previous undistorted condition before the brake caliper <NUM> was actuated in the first direction. Consequently, the bushing <NUM> may move in the second direction back toward its previous position when the caliper housing <NUM> moves in the second direction.

Optionally, a recoil resilient member <NUM> may be provided to bias the brake caliper <NUM> in the second direction. The recoil resilient member <NUM> may be disposed in the bore <NUM>. In at least one configuration, the recoil resilient member <NUM> may be spaced apart from the bore surface <NUM> and may not be received in the bushing <NUM>. The recoil resilient member <NUM> may be made of any suitable material that may display rubber-like elasticity as previously discussed with respect to the resilient member <NUM> and may configured as an O-ring, hollow tube or tubular structure, localized block, or the like. As such, the recoil resilient member <NUM> may absorb energy (e.g., store potential energy) when it is loaded and elastically deformed and may release energy when unloaded. The recoil resilient member <NUM> may be disposed near the second end <NUM> of a bushing <NUM>. For instance, the recoil resilient member <NUM> may be disposed against the second recess end surface <NUM>, may be disposed in a groove in the sleeve <NUM>, or combinations thereof. The recoil resilient member <NUM> may be positioned to engage or contact the second end <NUM> of a bushing <NUM> when braking is applied and the brake caliper <NUM> is moved in the first direction, such as to the position shown in <FIG>. The recoil resilient member <NUM> may be compressed in an axial direction (e.g., along or parallel to the axis <NUM>) by the bushing <NUM> when the brake caliper <NUM> moves to the position in <FIG>. Movement in the second direction from the positioning shown in <FIG> back toward the positioning shown in <FIG> when braking force is subsequently released may be aided by the recoil resilient member <NUM>. For instance, retracting the inboard brake pad assembly <NUM> may disengage and separate the inboard brake pad assembly <NUM> from the brake rotor <NUM> and the recoil resilient member <NUM> may then be allowed to release its potential energy and bias or urge the brake caliper <NUM> to slide in the second direction and back to or toward the positioning shown in <FIG>.

The bushing <NUM> may or may not slip with respect to the resilient member <NUM> when the brake caliper <NUM> slides in the first direction, the second direction, or both. For instance, the coefficient of friction between a resilient member <NUM> and the inner surface <NUM> of the bushing <NUM> may be greater than the coefficient of friction between the outer surface <NUM> of the bushing <NUM> and the bore surface <NUM>. The bushing <NUM> may slip in an axial direction with respect to the resilient member <NUM> if the applied force overcomes the static friction force between a resilient member <NUM> and the inner surface <NUM>.

A brake assembly having a slide pin assembly as described above may allow the brake caliper to slide along the outer surface of the bushing rather than having the brake caliper and bushing slide together such that the inner surface of the bushing slides along the sleeve. As such, the bushing may not be fixed to the brake caliper or assembled to the brake caliper with an interference fit. Such a configuration may allow the bushing to be more easily removed and replaced when worn. Moreover, such a configuration may allow the bushing to be loaded against the bore surface of the caliper housing, such as under a radial biasing force exerted by a resilient member, to help reduce clearance between the bore surface and the bushing and maintain contact with the bore surface as the outer surface of the bushing is worn. Accordingly, the resilient member and bushing may cooperate to compensate for bushing wear. In addition, the resilient member may help actuate the brake caliper when braking is released, thereby providing space for the outboard brake pad assembly to retract and disengage the brake rotor. As such, the brake assembly may facilitate disengagement of the outboard brake pad assembly from the brake rotor, which may help prevent the outboard brake pad assembly from dragging against a rotating brake rotor when braking is not applied. This in turn may reduce or eliminate unintended wear of the friction material of the outboard brake pad assembly, may help reduce friction and brake assembly temperatures, and may help improve fuel economy of the vehicle.
