Title:
ACTUATOR WITH CLUTCH MECHANISM
Document Type and Number:
Japanese Patent JPH01273734
Kind Code:
A
Abstract:
PURPOSE:To contrive the simplification of an operating mechanism for a throttle valve driving rod by providing a clutch, comprising a chuck urged by a spring and a pull wedge able to act by a solenoid, in a hollow cylindrical part in a gear drivable by a servomotor. CONSTITUTION:A hollow cylindrical part is formed in the inside of a gear 203 driven rotating by a servomotor, containing a chuck 301 of three-split structure, having a thread shaft rod 4, engageable thread groove 3011 and an external tapered surface 2012, being urged by a spring in an outer direction. A clutch mechanism is constituted providing a pull wedge 304, able to extend and retract by an electromagnetic solenoid 7, engageably with a wedge. The thread shaft rod 4 can be extended and contracted by driving the servomotor closing a clutch, and a throttle valve, connected to the other end of the thread shaft rod through a wire, is driven. A control of opening and closing the throttle valve in a fixed speed running control can be accurately performed by a simplified mechanism.
