摘要： A plurality of pinion gears 4A, 4B which are rotatably held within a differential case 2, and a pair of left and right side gears 6L, 6R which are in meshing engagement with the pinion gears 4A, 4B and connected to left and right axles are provided. A ring 18A is fitted around the pinion gears 4A, 4B to prevent the pinion gears 4A, 4B from being withdrawn. The ring 18A has an inner peripheral surface in which a spherical recess 18Aa centered about a point of intersection between an axis of rotation of the side gears 6L, 6R and an axis of rotation of the pinion gears 4A, 4B is formed while an end of the pinion gears 4A, 4B which is disposed toward the outer periphery is formed with a spherical projection 4Ac having a similar curvature as the recess in the ring 18A.

摘要： A differential assembly includes a differential housing (12) including a substantially spherically shaped chamber. A pair of spherically shaped side gears (36) are rotatably positioned in the chamber in driving communication with a pair of spherically shaped pinion gears (34). A pair of springs (90) are positioned in engagement with the end faces of the side gears (36) to minimize gear lash between the side gears (36) and the pinion gears (34).

摘要： The invention relates to a torque transmission differential for motor vehicles, said differential comprising: a casing (10) which is selectively rotated around axis y-y'; a drive wheel axle (20) with axis Y- Y'; a gearing (30) which is disposed inside the casing (10) and which transmits the rotation movement from the case (10) to the drive wheel axle (20); and a muzzle (40) which is solidly connected to the casing (10) and which is disposed between the gearing (30) and the internal surface (12) of the casing (10). Said gearing (3) generally lies within an ellipsoid of rotation and the muzzle (40) is more or less in the shape of an ellipsoid of revolution which is concentric to the gearing (30). According to the invention, said muzzle (40) comprises at least one first pair of shims (42).

摘要： The invention relates to a differential, in particular for a motor vehicle, comprising thrust washers (13, 14). Said differential is provided with a differential casing and several differential pinions, as well as two output shaft pinions as driving pinions. The thrust washers (13, 14) are arranged respectively between a driving pinion and the differential casing. The invention is characterized in that at least one anti-torsion element which acts by positive-fit is provided between one of the thrust washers (13, 14) and the differential casing.

摘要： A differential device for a vehicle, having enhanced durability achieved without involving vibration and noise in the device. A support section (68) for supporting a pinion gear (60) of a pinion shaft (56) and a pinion shaft (56) of the pinion gear (60) are inserted in a fitting hole (66). A part of the fitting hole (66) has tapered surfaces (70, 72) formed such that the closer to the outer peripheral side, the smaller the diameter. As a result, when driving force is transmitted from a differential case (50) to side gears (58l, 58r) through the pinion shaft (56) and the pinion gear (60) which is rotatably supported by the pinion shaft (56), the pinion gear (60) is moved outward in the axial direction of the pinion shaft by meshing reaction between the pinion gear (60) and the side gears (58l, 58r). A fitting clearance C between the pinion shaft (56) and the pinion gear (60) increases as a torque transmission load increases, and this provides the device with high durability.
