摘要： Limited slip differential, e.g. for vehicle transmissions, has a carrier (18) rotating about a first axis in a support casing (12) typically driven by a crown wheel (22) and main drive pinion (24). A pair of output half shafts (14, 16) on said axis have output pinions (28, 30) within the carrier meshing with at least one, and preferably a pair, of planet pinions (32, 24) journalled in the carrier on a second axis normal to first axis to allow differential motion of the output shafts while transmitting drive to both from the rotating carrier in known manner. Controlled shifting of the planet gear(s) relative to the carrier by angular displacement of the second axis in a diametral plane of the first axis from a neutral position to an inhibiting position, e.g. by displacement of a planet gear shaft (36) in slots (38) of the carrier, when the carrier is subjected to drive torque brings formations, e.g. end faces (42, 44) of the planet gears, into braking engagement with formations (46, 48) of the carrier so as to inhibit the differential action.

摘要： A bevel gear limited slip differential has a pinion carrier 18 supporting a pair of planet pinions 32,34 each containing a mating conical insert 78,80. The planet pinions are displaced outward when the carrier 18 is subjected to drive torque to bring them into frictional braking engagement with the carrier. The controlled outward displacement is obtained using an outward component of the rotating carrier drive torque force as it is transmitted to the said planet pinions from their contained conical inserts at the sloping interface between them. An adjustable preload on the pinions is provided by springs 54 and a sleeve assembly 52.

摘要： Limited slip differential, e.g. for vehicle transmissions, seen in FIG. 1, has a carrier (18) rotating about a first axis in a support casing (12) typically driven by a crown wheel (22) and main drive pinion (24). A pair of output half shafts (14, 16) on said axis have output pinions (28, 30) within the carrier meshing with at least one, and preferably a pair, of planet pinions (32, 34) journalled in the carrier on a second axis normal to first axis to allow differential motion of the output shafts while transmitting drive to both from the rotating carrier in known manner. Controlled shifting of the planet gear(s) relative to the carrier by angular displacement of the second axis in a diametral plane of the first axis from a neutral position to an inhibiting position, e.g. by displacement of a planet gear shaft (36) in slots (38) of the carrier, when the carrier is subjected to drive torque brings formations, e.g. end faces (42, 44) of the planet gears, into braking engagement with formations (46, 48) of the carrier so as to inhibit the differential action.
