PCT No. PCT/GB86/00462 Sec. 371 Date May 6, 1987 Sec. 102(e) Date May 6, 1987 PCT Filed Jul. 31, 1986 PCT Pub. No. WO87/00900 PCT Pub. Date Feb. 12, 1987.Limted slip differential mechanism for dividing input torque, applied to a splined sleeve (5) unequally between a front propeller shaft (7) and a rear propeller shaft (8) comprises a casing (10) (carrying the sleeve 5) in which are mounted for rotation about their respective axes a wormwheel (21ad) and front and rear worms (18D, 18A) meshing with opposite sides of the wormwheel (21ad) and being of sufficient length also to mesh with helical output gears (15,16) on the respective shafts (7,8). The rear output gear (16) is larger than the front output gear (15) so the torque is divided between the output gears in the ratio of their pitch circle diameters in the absence of substantial relative rotation while normal traction is maintained, but with limited slip if potential loss of traction occurs.
