<p>PCT No. PCT/GB93/02137 Sec. 371 Date Sep. 28, 1994 Sec. 102(e) Date Sep. 28, 1994 PCT Filed Oct. 15, 1993 PCT Pub. No. WO94/09291 PCT Pub. Date Apr. 28, 1994A differential mechanism (10) having two output cam members (16, 17) rotatable about an axis (A) each cam member having an annular cam surface of undulating form comprising pairs of mutually inclined surfaces (24, 25; 26, 27). The inclined surfaces are engaged by end surfaces (29, 30) of cam followers (28) so that relative contra rotation of the output cam members (16, 17) causes the cam followers to slide axially. An input element (11-14) engages and supports the followers (28) and moves the followers circumferentially relative to the output cam members and a component (11, 14) of the differential which rotates during use of the differential drives oil pump means (70) for forcing oil into the differential.</p> |
