The invention belongs to the technical field of automobile parts and relates to a trailer axle assembly. The trailer axle assembly comprises a cross beam, shells and lubricating units. Each lubricating unit comprises a storage bag, a first wheel, a second wheel, an air bag, an arc-shaped piston cylinder and a gear rolling block; through cooperation of the cross beam, the shells and the lubricatingunits, the interiors of the shells are automatically lubricated; when sponge brushes leave the storage bags along with the rotation of the second wheels, the sponge brushes coat lubricating grease adhered to the sponge brushes on the surfaces of the internal structures of the corresponding shells. According to the trailer axle assembly, an automatic lubricating effect on the axle is achieved; thedisassembly and assembly of the shells and a brake drum system assembly are avoided; the working efficiency of maintenance personnel is greatly improved; the maintenance period of the axle by a useris shortened; the lubricating grease is only needed to be replenished into the storage bags regularly; and the overall using effect of the axle is greatly enhanced.
本发明属于汽车零部件技术领域,具体的说是一种挂车桥总成;包括横梁、壳体和润滑单元;润滑单元包括储料囊、一号轮、二号轮、气囊、弧形活塞缸和搓齿块;通过横梁、壳体和润滑单元的配合对壳体内进行自动润滑,当海绵刷随着二号轮的转动离开储料囊后,海绵刷将自身粘附的润滑脂涂在壳体的内部结构表面,实现对车桥的自动润滑作用,避免了拆装壳体及制动鼓系统总成,从而极大的增加了维修人员的工作效率,并减小使用者对于车桥保养的周期,只需定时向储量囊内补充润滑脂,极大的增强了车桥的整体使用效果。
