LIMITED SLIP DIFFERENTIAL INCORPORATING BEVEL PINIONS

摘要

A differential mechanism (1) includes a carrier housing (2) adapted to be rotatably driven about a longitudinal axis (3). A pair of independent coaxial parallel side gears (4, 5) are supported for rotation about the axis (3). The carrier housing (2) includes two inner peripherally spaced part-spherical recessed pinion cavities (6) defining respective inwardly directed housing thrust surfaces (7). Two floating bevel pinions (8), each in a meshing engagement with the side gears (4, 5), have respective pinion outer and inner thrust surfaces (9, 10). The outer thrust surfaces (9) are adapted for frictional rotation within the recess cavities (6). A cubic thrust block (12) is supported generally within the carrier housing (2) by a cross shaft (11) and defines four outwardly directed thrust directed thrust surfaces (13, 16).
