The invention discloses a tractor rear drive axle assembly and a tractor. A differential mechanism assembly is installed in a drive axle shell. The hub reduction gearbox is arranged outside the drive axle shell and connected with the differential mechanism assembly through a half shaft. The wet brake assembly is arranged in the drive axle shell; the hydraulic electric control system is arranged on the drive axle shell; one end of the precise lubricating system is connected with the hydraulic electric control system, and the other end of the precise lubricating system is connected with the wet brake assembly and the differential assembly; the drive axle shell is provided with a lubricating oil channel communicated with the wet brake assembly and the differential assembly. According to the invention, modular design is adopted, the device can be integrally independent of the main gearbox of the tractor, all parts which are easy to break down are integrated outside the shell, and rapid diagnosis and maintenance of the fault can be realized. Forced and accurate lubrication control is adopted for internal quick-wear parts, splashing and immersion lubrication are matched, and faults caused by poor lubrication of the internal parts can be effectively avoided.

    本发明公开了一种拖拉机后驱动桥总成及拖拉机,驱动桥壳体内部安装有差速器总成;轮边减速箱设置在驱动桥壳体外部,且轮边减速箱通过半轴与差速器总成相连;湿式制动器总成设置在驱动桥壳体内部;液压电控系统设置在驱动桥壳体上;精准润滑系统一端与液压电控系统连接,另一端分别与湿式制动器总成和差速器总成连接;驱动桥壳体上设置有连通至湿式制动器总成和差速器总成的润滑油道。本发明采用模块化设计,可整体独立于拖拉机的主变速箱,将易发生故障的零件全部集成在壳体外部,可实现故障的快速诊断与检修。内部易损件采用强制与精确润滑控制,配合飞溅及浸入式润滑,可有效避免内部零件因润滑不良引起的故障。
