摘要： A limited slip differential, comprising: a plurality of planetary gears; a planetary carrier for supporting the planetary gears in such a manner that the planetary gears can rotate on their axes and revolve while making contact with and sliding against a surface of teeth of the planetary gears; and a sun gear and a ring gear which are arranged coaxially with the planetary carrier and are allowed to differentially rotate by means of the planetary gears, wherein the limited slip differential limits differential motion generated between the sun gear and the ring gear, irregular unevenness is created on at least either of the surface of the teeth of the planetary gears, and the sliding surface of the planetary carrier which makes contact with and slides against the surface of the teeth, the limited slip differential being characterized in that:
the surface where the irregular unevenness is created has such a surface roughness that the maximum value of the power of a pitch of 40 µm to 60 µm as found through Fourier analysis is 0.4 µm to 1.2 µm.

摘要： A differential assembly includes a differential housing (12) defining a chamber (14) and a pair of aligned openings (24,26) communicating with the chamber (14). A pair of output shafts (28a,28b) extend through the openings (24,26) in the differential housing (12) and include end segments located within the chamber (14). A pair of side gears (36) are positioned within the chamber (14) and fixed to the end segments of the output shaft (28a,28b). Paired sets of pinions (34) are rotatably mounted within the differential housing and placed in meshed engagement with each other and with one of the side gears (36). A retention assembly (42) interconnects the end segments and includes a spacer (64) having a web positioned between and walls partially encompassing the end segments. The retention assembly (42) includes a ring (62) surrounding the spacer (64) to selectively retain and allow removal of clips (48a,48b) engaged with the end segments.
