TRANSMISSION LOCK AND SUPERPOSITION STEERING SYSTEM COMPRISING A TRANSMISSION LOCK

摘要

The invention relates to a transmission lock for a superposition steering system of a motor vehicle for locking a rotatable transmission element associated with the transmission or interacting with the transmission with respect to its rotational movement. The invention is characterized in that a clamping element, especially a clamping roller (7), is used to positively lock, via a contour of an inner peripheral surface (inner contour) of an outer ring (2) and a contour of an outer peripheral surface (outer contour) of an inner ring (4), the inner ring with the outer ring against an elastic force. The clamping roller is retained in an activation cage (5) that can be locked via an actuated locking member.
