Abstract:
A vehicle braking and suspension system comprising:a vehicle suspension having a suspension member; a wheel adapted to be carried by the vehicle suspension member; a disc brake and wheel support assembly having a supporting suspension member; a rotatable hub mounted on the suspension member for rotation about a central rotational axis through the hub and carrying the wheel for rotation about the rotational axis; a brake actuator for the disc brake mounted on the supporting suspension member; a stationary bridge on the suspension member and having slidable surfaces thereon; a brake disc mounted on the hub for braking the hub and wheel; a drive connection between the hub and the brake disc to rotate the brake disc with rotation of the hub and to decelerate the rotation of the hub when the disc is in the braking position; an outer, fixed brake pad mounted on the bridge for engaging one side of the brake disc; a slidable brake pad mounted on the slidable surfaces of the stationary bridge and slidable by the brake actuator to engage a friction surface thereon with the other side of the disc and to slide the brake disc axially along to the hub from an off-brake, residual torque position to a on-brake position in which the braking pads are engaging opposite sides of the brake disc to brake the disc, hub and wheel; a brake pad force applicator carried on the stationary bridge applying force to the brake pad to hold the brake pad in a plane parallel to the plane of the slidable brake disc; the drive connection between the disc and hub comprising intermeshed teeth; and the teeth on the brake disc being provided with stress relief fillets at the junctures of the teeth to the remainder of the brake disc.
