The differential comprises a drive input element 40 two outputs cam members 16, 17 rotatable about an axis A, each said member having a single annular cam surfaces 22, 23 thereon of undulating form arranged such that the cam surfaces on the cam members converge towards each other, and a plurality of cam followers 28. The followers have cam engaging end surfaces 29, 30, 32, 33 for imparting drive from the input element 40 to said output cam members. Relative contra rotation of said output cam members causes the cam followers to slide axially. The cam followers 28 are elongate in the direction of axis A and are slidably supported throughout virtually their entire length by the drive input element 40. The followers 28 may be arranged closely adjacent each other to provide a degree of mutual support. |
