Device for operating a braking apparatus

摘要

The brake actuating device has an axially movable rod with an expanding cylindrical base with several elongated holes in its floor arranged at intervals on a circle and a radial peripheral groove in its outer surface and a distance ring inside the cylindrical base between the rod and a piston and acting as a component for implementing a no-load displacement. The distance ring has several peripheral elements protruding into the elongated holes. The brake actuating device has an axially movable rod (4) with an expanding cylindrical base (14) with several elongated holes (18) in its floor arranged at intervals on a circle and a radial peripheral groove (22) in its outer surface and a distance ring inside the cylindrical base between the rod and a piston and acting as a component for implementing a no-load displacement. The distance ring has several peripheral plates (20) protruding into the elongated holes.
