DEVICE FOR COMBINED CONTROL OF VEHICLE GEARS AND CLUTCH Russian patent published in 2007 - IPC B60K1/00 

FIELD: transport engineering.

SUBSTANCE: proposed device has dc supply source, clutch release chamber, gearshift lever with movable handle, cable in sheathing, dc motor, drive shaft, step-down reduction gear with variable profile cam acting onto pusher of clutch release chamber. Motor speed is controlled by electric control circuit containing engine crankshaft speed pickup, gearbox main shaft speed pickup, vehicle movement resistance moment pickup, accelerator pedal position pickup, all connected by electric circuit with electronic control unit and with inductance coil whose core is connected by tie-rod with sliding contact of electric motor current regulating rheostat. Spring acts on to sliding contact of rheostat, and fixed contact of rheostat is connected by electric circuit with dc electric motor through two electric switches. Cable in sheathing acts onto one switch and movable pusher acts onto other switch. Pusher is furnished with spring and is arranged with body of drive shaft of variable profile cam.

EFFECT: improved reliability of operation of clutch and transmission of vehicle.
