Abstract

The engageable and disengageable friction clutch between the prime mover and the gearbox in the power train of a motor vehicle can be adjusted by an electric motor against the opposition of at least one resilient element by applying rest current from a source to an electric motor which opposes the bias of the resilient element in response to detection, by a sensor, that the bias of such resilient element upon a displaceable clutch actuating member exceeds the force then being exerted by the clutch. The application of rest current to the motor normally takes place when the vehicle is started and/or subsequent to shifting of the gearbox into a different gear. The thus actuated motor can prevent a worm wheel gearing or an analogous motor-operated component from partially disengaging the clutch when the disengagement is undesirable or harmful.
