    • A differential gear system for a vehicle includes a casing having two sun gears connected to half shafts for the vehicle's wheels, and two sets of planetary differential pinions surrounding the sun gears. Each set of differential pinions is in meshing engagement with one of the sun gears, and the two sets are also in meshing engagement with one another. Each pinion of one set is engaged with two adjacent pinions of the other set, all of the pinions collectively arranged in a circle surrounding the axis of the sun gears. Each pinion is enclosed in a pocket in the casing, the pockets intersecting to allow engagement of the pinions with one another. Each pocket also encloses a pressure pad, a spring, and a pressure washer on the axial outer end of the enclosed pinion. The springs bias the pressure pads against the pinions to provide frictional resistance against differential action. For each pocket, a set screw is provided in an axial threaded bore of the casing, the end of the set screw bearing upon the pressure washer. Adjustment of the set screws permits fine tuning of the system's frictional resistance to differential action.
    • 用于车辆的差速齿轮系统(20)包括:壳体(22),其具有连接到用于车辆车轮的半轴的两个太阳齿轮(28,30)和围绕太阳齿轮的两组行星差速齿轮(60)。 每组差速器小齿轮与太阳齿轮中的一个啮合,两组也彼此啮合。 一组的每个小齿轮与另一组的两个相邻的小齿轮啮合,所有小齿轮共同地围绕着太阳齿轮的轴线布置。 每个小齿轮被封装在壳体中的凹槽(58)中,凹口(58)相交以允许小齿轮彼此接合。 每个口袋还在封闭的小齿轮的轴向外端上包围压力垫(48,62),弹簧(50,64)和压力垫圈(52,66)。 弹簧将压力垫偏压在小齿轮上,以提供抵抗差速作用的摩擦阻力。 对于每个口袋,固定螺钉(56,70)设置在壳体的轴向螺纹孔(54,68)中,固定螺钉的端部承载在压力清洗器上。 固定螺丝的调整允许微调系统的摩擦阻力以达到差速动作。

    • A parallel-axis gear differential has pairs of top and bottom planet gears (38 and 40, 42 and 44, and 46 and 48) operatively connecting a pair of side gears (30 and 32). Each of the planet gears has a main gear section (74, 80) and a transfer gear section (76, 82) interconnected by a stem section (78, 84). Teeth (86 and 88) of the side gears (30 and 32) are separated through a clearance space (100) formed by a hub (98) of side gear (32). Within the clearance space (100), teeth (90 and 94) of the main planet gear sections (74 and 80) overlap the side gear teeth (86 and 88). Inner and outer ends (102 and 104) of the side gear teeth (86 and 88) ane inclined at a chanfer angle (A) throughout a distance that extends between top and bottom lands (106 and 108) of the side gears.

    • Frictional resistance is appreciably increased in parallel-axis/torque-proportioning types of automotive differentials to improve torque bias characteristics. A pair of sun gears (15, 17) receive, respectively, the ends of coaxial drive axles, and the sun gears (15, 17) are interconnected by at least one planetary pair of combination gears (23, 25) positioned in the housing circumferentially around the sun gears (15, 17). Each combination gear (23, 25) of the pair has a first engagement portion (27, 29) that is in mesh with a respective one of the sun gears (15, 17), and each also has a second engagement portion (31, 33) that is in mesh with its paired combination gear (23, 25). The first engagement portion (27, 29) of each combination gear (23, 25) is designed to develop end thrust on the combination gear to increase the frictional resistance between an end face of the gear and a bearing surface of the housing whenever the differential is subjected to a torque difference between its respective sun gears; and the gear's second engagement portion is specifically designed so that it develops either (a) no end thrust in a direction opposite to the direction of the end thrust developed by the first engagement portion or (b) end thrust in the same direction.
