摘要：An actuator for brakes with automatic adjustment suitable in particular forheavy duty vehicles comprises a housing (32) whose axis (A) is surrounded by a camsurface (36). A rotary member (40) is rotatable about the housing axis (A) and comprises asecond cam surface (42) with which it bears on the first cam surface (36) to produce anaxial displacement dependent on its rotation. A first screw member (50) is likewiserotatable about the housing axis and a second screw member (60) is formed to exert anactuating force on a brake pad. The second screw member is connected to the first screwmember by a pair of threaded adjustment members (62). A reset shaft (92) is mounted inthe housing (32) and permits a screwing back of the two screw members (50, 60) withrespect to each other to replace the brake pad. The reset shaft (92) is disposed withlateral spacing from the housing axis (A) and is connected to one of the screw members(50) via a gearing ( 88, 90).
