Abstract
A differential mechanism having two output cam members rotatable about an axis, each cam member having a single annular cam surface of undulating form comprising pairs of mutually inclined surfaces. The inclined surfaces are engaged by end surfaces of followers so that relative contra rotation of the output cam members causes the cam followers to slide axially. An Input element engages and supports the followers and moves the followers circumferentially relative to the output cam members. The input element engages with a radially inner portion of each cam follower to move the follower circumferentially relative to the cam output members, and the cam surfaces are inclined away from the axis of rotation.
