Abstract

The invention relates to a mechanical automatic speed changer clutch actuating mechanism. The mechanism comprises a clutch driving device and a clutch master cylinder assembly, wherein the clutch driving device comprises a clutch electric motor (8), a clutch electric motor worm (9), a clutch electric motor worm wheel (10) and a clutch gear (15) engaged with the clutch electric motor worm wheel (10); and the clutch master cylinder assembly comprises a master cylinder piston (12). The mechanical automatic speed changer clutch actuating mechanism is characterized in that the inside of a clutch casing (7) is provided with a clutch rack assembly; and the clutch driving device is connected with the clutch master cylinder assembly through the clutch rack assembly. Due to the adoption of the technical proposal, the mechanical automatic speed changer clutch actuating mechanism has the advantages of simple structure and smooth transmission.

Description

technical field [0001] The invention relates to a mechanical automatic transmission clutch actuator. Background technique [0002] The existing mechanical automatic transmission clutch actuator generally adopts two methods of motor control and hydraulic control. The motor control mainly adopts the structure of a motor with a screw and a nut. The rotation of the motor drives the screw to rotate, and the rotation of the screw drives The nut reciprocates to realize the separation and combination of the clutch; the hydraulic control mainly adopts a motor-crank-connecting rod structure, and the motor drives the movement of the crank-connecting rod mechanism to drive the reciprocating movement of the piston of the hydraulic cylinder to realize the separation and connection of the clutch. combined. Although these two methods can make the clutch disengage and combine, the transmission methods adopted by the two methods are relatively complicated, and the parts are complicated and d...
