Abstract

The invention discloses an electric operator for a general-purpose mechanical automatic transmission clutch, which comprises a servo motor, a shell, a coupling, a connector, a front end flange, a back end flange, a bearing, a hinge pin, a ball screw, a pressure sensor, a spacing sensor and a displacement sensor, wherein the front end flange fixes the shell on the clutch bracket; the motor is fixed on the shell; the output shaft of the motor is connected with the screw stem of the ball screw through the coupling; the screw stem drives a screw stem shaft sleeve through balls to drive a push rod to move; and the other end of the push rod is connected with the pressure sensor, thereby finally acting on the driving lever of the clutch, so that the driving lever drives the clutch to move. The invention has the advantages of simple structure, high transmission efficiency, accurate control and the like, is suitable for clutches with different rigidities and movement strokes, and can monitor the movement state of the clutch from different angles. The invention is mainly used in electric operators for clutches in experimental study.

Description

Technical field:

[0001] The invention relates to an automobile clutch actuator, in particular to a universal mechanical automatic transmission clutch electric actuator. technical background:

[0002] The actuators of automatic mechanical transmission (AMT) clutches can be mainly divided into three types: pneumatic, hydraulic and electric. Among them: the pneumatic actuator mainly uses a single-acting or double-acting cylinder to drive the clutch to realize the separation and engagement of the clutch. The working medium is air, which has the advantages of low cost and no pollution to the environment after use, but the pressure of compressed air is low. , the compressibility of the air is large, the stability of the pneumatic control is poor, the precision is low, the noise is large, and there is moisture in the air, which affects the service life of each component, and filter equipment is required; the hydraulic actuator is powered by an oil pump, and the pump The high-press...
