Abstract: An automatic clutch control system, for use in automobiles, using a microcomputer. Included in the system are an accelerator pedal sensor for detecting accelerator position; an engine speed sensor for detecting engine speed; a clutch stroke sensor for detecting clutch stroke; and an automobile speed sensor for detecting automobile speed. The microcomputer is included in a controller for controlling opening or closing of solenoid valves, gear change of a transmission, and opening or closing of a throttle actuator, based on predetermined stored data and based on signals transmitted from the sensors. The automatic clutch control system consequently can automatically control the clutch moving time and clutch moving speed for easy driving under all driving conditions. Moreover, while the clutch control system is fully automatic, it can use dry-type single-plate clutches and sliding-mesh-type transmissions as in manual and semiautomatic transmissions.

The gear changing lever is adapted to pivot by a depressing action against the force of the first spring member to disengage the idle gear axle from the one end of the elongated opening so as to allow a second spring member to urge the idle gear axle against the other end of the elongated opening.

Abstract: A damper disk comprises a pair of side plates at both sides of a flange of a hub splined to an output shaft. Both side plates and the flange are connected each other through torsion springs. One or a pair of sub-plates are disposed between the flange and the side plates.

Frictional force between the flange 2 and the sub-plate is set stronger than that between the side plates and sub-plates. According to the invention, hysteresis torque changes during torsional operation, thereby, noises during idling of the engine as well as acceleration can be prevented.
