摘要： In some examples a piston-bushing assembly includes a bushing with an opening and a piston slidably disposed within the bushing. The piston includes a bottom end disposed within the bushing and an exterior end extending a distance outward from the opening of the bushing. The exterior end of the piston is configured to engage with a disc stack of a brake assembly. The piston-bushing assembly also includes an adjuster tube including a first end of the adjuster tube, wherein, when the piston-bushing assembly is in an unactuated state, a length between the first end of the adjuster tube and the bottom end of the piston defines a step-back gap.

摘要： The present application relates to crushable body in the form of a corrugated thin walled tube e.g. for use in a piston assembly (30) for engaging two selectively engageable parts (21, 39). The piston assembly (30) has a housing (32) defining a piston cylinder and a piston (31). The assembly (30) also has a piston stroke limiter (70). The piston stroke limiter (70) is configured to limit the length of a return stroke of the piston (31) from an extended stroke position and a retracted stroke position. A crushable body (60) in the form of a corrugated thin walled tube acts between the piston (31) and the piston stroke limiter (70) and is arranged to reduce in axial length when a length of an extended stroke exceeds a length of a retraction stroke to maintain the length of the return stroke.
