Abstract: An actuator includes a motor and a gearbox connected with the motor. The gearbox has a lower housing, a gear received in the lower housing, and a cover disposed at one end of the lower housing. The lower housing has a support shaft supporting the gear for rotation relative to the lower housing. The support shaft is hollow. A core shaft is inserted into the support shaft. The core shaft is made of a metal material and the support shaft is made of a plastic material.

Abstract: An automated manual transmission comprises a hydraulic pump and a motor for driving the hydraulic pump. The motor comprises a stator and a rotor rotatably mounted to the stator, the stator comprising a housing and a motor end cap fixed to the housing, the rotor comprising a rotatable shaft rotatably supported by a bearing which is installed to the end cap. The bearing comprises an inner race, an outer race, rollers disposed between the inner race and the outer race, and roll holder for holding the rollers. A ring-shaped seal member is arranged at one axial end of the bearing to seal the gap between the inner race and outer race. The end cap is molded at outer peripheral surface of the outer race.
