Abstract
The electric park brake of the present invention includes an electric caliper motor assembly. The electric caliper motor assembly includes a motor, which is operably coupled to a shaft. The motor and shaft are surrounded by a housing. A cogwheel is disposed axially and operably connected to the shaft within the housing. A solenoid mechanism is disposed on the housing and positioned axially in relation to the shaft. There is at least one guide pin that is associated with the solenoid mechanism for interacting with the cogwheel when the solenoid is activated. The interaction between the at least one guide pin and the cogwheel provides a park brake feature and prevents movement of the shaft.
