Abstract

The invention provides an electrohydraulic automatic clutch actuating mechanism which comprises a motor, a worm gear, a ball screw, a housing and a main hydraulic cylinder, wherein the housing is provided with an inner cavity penetrating in an extension direction of the housing; one end of the inner cavity is sealed by a plug lid; the other end of the inner cavity is in sealing connection with themain hydraulic cylinder; a bearing is fixedly arranged in the inner cavity; the ball screw is arranged in the inner cavity; a nut of the ball screw is rotationally connected with the bearing; one end, close to the plug lid, of a threaded rod of the ball screw is free; the other end of the threaded rod extends into the main hydraulic cylinder and is connected with a piston of the main hydraulic cylinder; the motor is in sealing connection with the housing; an output shaft of the motor penetrates through the housing and is located in the inner cavity; the output shaft of the motor is sleeved with the worm gear; the worm gear is located in the inner cavity; a helical gear of the worm gear is rotationally connected with the nut of the ball screw; and the worm gear rotates to drive the nut torotate. The electrohydraulic automatic clutch actuating mechanism solves the problems that a hydraulic automatic clutch is not compact in structure and large in size, and the loss of power transmittedby the motor is large in the prior art.

Description

technical field

[0001] The invention belongs to the field of motor vehicle control and relates to an electro-hydraulic automatic clutch actuator. Background technique

[0002] The clutch operating mechanism is a set of mechanisms used by the driver to disengage the clutch and then make it softly engaged. It starts at the clutch pedal and ends at the release bearing inside the flywheel housing. At present, the clutches used in automobiles are divided into traditional clutches and automatic clutches according to the difference between manual transmission and automatic transmission. The difference between the two is mainly reflected in the difference in the clutch control mechanism.

[0003] The operating mechanism of the traditional clutch mainly includes a mechanical hydraulic clutch operating mechanism. This operating mechanism is mainly composed of a clutch pedal, a clutch master cylinder, a clutch slave cylinder, etc., and the clutch master cylinder is pushed by the drive...
