A WEDGE AND ROLLER BRAKE ACTUATOR

摘要

Inwardly directed thrust arising on one of the tappets (4) is transmitted to an abutment surface provided on an insert secured to the body (l) or directly formed on the actuator housing (l) either by additional rollers or by one of the rollers (9, l0). In one convenient arrangement, the surface (llA) reacting said inwardly directed force is inclined to the longitudinal axis (A) of the wedge in the opposite direction to the opposed wedge surface (7A).
