The invention discloses a lightweight differential assembly of a heavy truck, which relates to the technical field of differentials and comprises a first sleeve shell and a second sleeve shell, and a plurality of weight reduction grooves are formed in the first sleeve shell and the second sleeve shell; a plurality of counter bores are formed in the connecting end face of the first sleeve shell, and a plurality of first screw holes are formed in the connecting end face of the second sleeve shell. A driven tooth is arranged between the first sleeve shell and the second sleeve shell, a plurality of second screw holes are formed in the connecting end face of the driven tooth, and the counter bores, the first screw holes and the second screw holes are in one-to-one correspondence. By accurately controlling the shapes of the first sleeve shell and the second sleeve shell, a base body formed after the first sleeve shell and the second sleeve shell are assembled is reduced, and meanwhile weight reduction grooves are formed in the first sleeve shell and the second sleeve shell to reduce the weight; positioning spigots are arranged on the contact faces of the driven gear and the first sleeve shell and the second sleeve shell respectively, positioning spigots are also arranged on the first sleeve shell and the second sleeve shell, and the corresponding positioning spigots are connected in a matched mode, so that double positioning of the driven gear can be achieved, the overall weight is reduced, and light weight of the overall structure is achieved.

    本发明公开了一种重型汽车轻量化差速器总成,涉及差速器技术领域,包括套壳一和套壳二,套壳一和套壳二内部均开设有多个减重槽;套壳一的连接端面上开设有多个沉孔,套壳二的连接端面上开设有多个第一螺孔;套壳一与套壳二之间设有被齿,被齿的连接端面上开设有多个第二螺孔,多个沉孔、第一螺孔以及第二螺孔一一对应;通过精准控制套壳一与套壳二的形状,缩减套壳一与套壳二组装后的基体,同时在套壳一与套壳二内部均设置减重槽减轻重量;在被齿与套壳一和套壳二的接触面上分别设有定位止口,在套壳一和套壳二上也设有定位止口,对应的定位止口配合连接,可以实现对于被齿的双定位,也减轻了整体重量,实现了整体结构的轻量化。
