PCT No. PCT/GB94/00987 Sec. 371 Date Dec. 22, 1994 Sec. 102(e) Date Dec. 22, 1994 PCT Filed May 6, 1994 PCT Pub. No. WO94/27065 PCT Pub. Date Nov. 24, 1994A differential mechanism having two output cam members rotatable about an axis (X-X), each cam member having a single annular frustoconical cam surface thereon of undulating form comprising pairs of mutually inclined surfaces and a plurality of cam followers having end surfaces engaging the cam surfaces of the output cam members. Relative contra rotation of the output cam members causes the cam followers to slide axially and an input member engages the followers which are slidably supported by the input member and moves the followers circumferentially relative to the output cam members. A locking means is also provided for locking the output cam members and/or the input member against relative rotation to lock up the differential mechanism. |
