Abstract:
1. An actuator assembly, comprising: a housing; at least one rotating gear member including a cam; an actuator device operably connected to said at least one rotating gear member, operably contained in said housing, for rotating said at least one rotating gear member; a bearing member operably associated with said cam such that when said actuator device is actuated for rotation of said at least one rotating gear member, said bearing member moves on said cam for providing relative motion between said bearing member and said at least one rotating gear member; a shaft, said at least one rotating gear member being operable with said shaft, and said shaft is supported in said housing; a spring mounted about said shaft and engaged with said housing, and said at least one rotating gear member mounted on said shaft, said spring operates to resist torque applied from said actuator device, and holds said rotating gear member mounted on said shaft in a stationary position, said spring also applying force to said rotating gear member mounted on said shaft when no torque is applied from said actuator device; and a position sensor for sensing the position of either of said at least one rotating gear member, said shaft, or said bearing member.
