Actuator for mechanical automatic transmission clutch

Abstract

The invention relates to an actuator for a mechanical automatic transmission clutch. The actuator comprises a clutch motor, a worm, a worm gear, a planetary gear train, a shift fork shaft and a clutch shift fork, wherein the worm is connected with an output shaft of the clutch motor; the worm gear is meshed with the worm; the planetary gear train comprises a sun gear, two or more planet gears meshed on the periphery of the sun gear, a planet carrier fixedly connected with each planet gear and gear rings respectively meshed on the outer side of each planet gear; the sun gear is coaxially fixedly connected with the worm gear; one end of the shift fork shaft is fixedly connected with the planet carrier; the clutch shift fork is fixedly connected to the shift fork shaft. The actuator can be widely applied in the mechanical automatic transmission clutch.

Description

technical field [0001] The invention relates to an automatic clutch, in particular to a mechanical automatic transmission clutch actuator. Background technique [0002] In the prior art, most of the actuators of mechanical automatic transmission clutches use worm gears to drive racks and pinions, and finally realize the automatic engagement and separation of clutches through lever mechanisms. There are several defects in this mechanism: first, from the point of view of structural principle, it has only gone through one stage of worm gear reduction, and the requirements for the motor are relatively high; second, the use of lever mechanism and rack and pinion mechanism will make the whole The mechanism occupies a large volume; third, the biggest problem of the lever mechanism is that its debugging is difficult and complicated, resulting in increased production cycle and cost; fourth, the clutch disengagement time is long, resulting in long power interruption time and poor driv...
