Self-energizing electromechanically actuable disc brake for commercial vehicle, has pressure piston with slight play between guide surfaces of braking plate such that tangential forces are supported by piston on plate during braking

摘要

The brake has a self-energizing device comprising a pressure piston that is stationary during braking. The piston is movable parallel to a brake disc rotational axis during an adjusting movement, and is connected with an adjusting device. The piston is with the slight play parallel to the rotational axis between guide surfaces of a braking plate (31) such that tangential forces are directly supported by the piston on the braking plate during braking.
