MOC Motor On CaliperMOC actuator for Electronic Parking BrakeEPB

摘要

The present invention relates to a MOC actuator for an electronic parking brake, comprising: a housing having a first installation space portion and a second installation space portion therein; A motor installed in the first installation space of the housing and having a pinion gear installed at an end of the motor shaft; A ring gear installed in the second installation space of the housing; A power transmission gear and an output unit installed on the ring gear; An idle gear interposed between the power transmission gear and the pinion gear; And a housing cover for closing the open upper portion of the housing, wherein a first coupling protrusion protruding to fit into the first coupling hole of the idle gear between the first installation space portion and the second installation space portion of the housing And a second coupling protrusion fitted to correspond to the second coupling hole of the idle gear on an inner wall surface of the housing cover. Accordingly, the configuration of separate idle pins, pin bushes, brackets, and ring gear covers can be eliminated, thereby simplifying the assembly process accordingly to greatly improve product productivity and significantly lower manufacturing costs. have.
