Abstract:
1. A wedging clamp device for insertion between two parts, capable of performing a relative movement in relation to one another, in order to prevent relative movement between a brake disk and a brake caliper of a vehicle brake, comprising: two plates, at least two opposed rollers, rolling on rolling surfaces on opposing inner sides of the plates, by which a separation between the plates is adjustable, a first actuating device by which a position of the rollers relative to the rolling surfaces is adjustable, and at least two wedges that can be wedged against one another, at least one of the wedges being actuatable by a second actuating device in the wedging or release direction, wherein the first actuating device has a spring, which preloads the plates into the deployed position, wherein each of the rollers, viewed in an axial direction, has, at least in sections, a circumferential external toothing, which meshes with toothing systems on the rolling surfaces, wherein separation of the plates, for bringing about a wedging in an extended state, is greater when the rollers are situated in the area of a first section of the rolling surfaces than the separation, assumed by the plates for release of wedging in a retracted state, when the rollers are situated in the area of a second section of the rolling surfaces, wherein the first actuating device first brings the plates from their retracted position into their extended position and the second actuating device then actuates said at least one of the wedges in a direction preventing relative movement between the brake disk and the brake caliper in order to bring about wedging, and wherein the first actuating device brings the plates from their extended position into the retracted position and the second actuating device actuates said at least one of the wedges in a direction allowing a relative movement between the two parts in order to release the wedging.
