Abstract
The invention belongs to the field of clutch actuating mechanisms. An automatic transmission clutch actuating mechanism comprises a clutch motor, a screw rod, a shifter shaft fixedly connected with a clutch shifter, and a transmission mechanism comprising a nut, a gear and a rack. The nut is in threaded connection with the screw rod and can move along the screw rod, the gear is fixedly connected with the shifter shaft, and the rack is fixedly connected with the nut. The rack is matched with the gear, drives the gear to rotate and accordingly drives the shifter shaft to rotate. The automatic transmission clutch actuating mechanism uses the transmission mechanism comprising the nut, the gear and the rack to take the place of a worm wheel in the prior. The nut moves along the screw rod and is small in fiction force. The gear is matched with the rack, the transmission efficiency is high, and the service life is long. By means of the transmission mechanism, the problem of low transmission efficiency caused by the worm wheel and a worm in the prior art is solved.
