Clutch with two pressure plates and one stop

摘要

A clutch has two pressure plates that are provided with conical teeth facing one another on opposing faces of the pressure plates. The conical teeth resolve relative rotation between the pressure plates into axial force pushing the plates apart, thereby to press the clutch disks together to engage the clutch. A selectively engageable stop is provided on one of the pressure plates to permit limited, unlimited, or no relative rotation between the pressure plates. The stop is controlled depending on parameters such as steering angle and direction of travel. Two such clutches can be applied to the differential of a vehicle drive.
