ACTUATOR FOR PARKING BRAKE

摘要

The invention relates to an actuator (10) for parking brake comprising a housing (12) defining a recess (14), and driving means (16) operatively interposed between a driving member (18) and a braking member. The driving means (16) are at least partially housed in the recess (12), and comprise a first washer (26), a second washer (28) translatable relative to the first washer (26) along a drive axle (20) upon the action of the driving member (18), and a pushing device (30) translatable along the drive axle (20) following the relative movement of the two washers. The pushing device (30) is operatively associated to the braking member. The actuator further comprises a cage (56) adapted to at least partially house first washer (26), second washer (28), and a portion of the pushing device (30), and to define an abutment for return means (58). The cage (56) comprises snap-coupling portions on the first washer (26).
