摘要： A differential gear mechanism includes a housing, first and second sun gears each including an external gear portion, and first and second planetary gears. The first and second sun gears include axial end surfaces pressed against contact surfaces provided at the housing by the first and second sun gears by means of thrust forces generated at engagement surfaces between the external gear portions and the planetary gears. Each of the sun gears includes a first portion having the external gear portion, a second portion, and a thrust force generating mechanism for generating thrust forces at the first portion and the second portion. A direction of the thrust force generated at the first portion by the thrust force generating mechanism is specified to be equal to a direction of the thrust force generated at the first portion by means of the engagement between the external gear portion and the planetary gear.

摘要： A coil spring preload system is applied to a parallel-axis differential having a thrust block interposed between ends of axles splined to side gears within the differential. A pair of spring plates are interposed between the thrust block and the side gears, and the spring plates retain preload coil springs arranged in sectors between the thrust block and planetary gears of the differential. The spring plates are retained against rotation relative to the differential housing, preferably by piloting against the planetary gears. U-shaped access openings in the spring plates to allow application of C-clips retaining axle ends within the differential are preferably closed by filler plates having the same thickness as the spring plates.
摘要翻译：螺旋弹簧预加载系统被施加到平行轴差速器，其具有插入在差速器内的侧齿轮的轴的端部之间的推力块。推力块和侧齿轮之间夹有一对弹簧板，并且弹簧板保持预紧螺旋弹簧，其布置在差速器的推力块和行星齿轮之间的扇区中。弹簧板相对于差速器壳体保持抵抗旋转，优选地通过对着行星齿轮进行驾驶。弹簧板中的U形进入开口允许将保持轴端的C形夹应用在差速器内，优选地与具有与弹簧板相同厚度的填充板封闭。
