The invention discloses a running and parking integrated wet brake drive axle which comprises an axle housing mechanism, a main reduction mechanism, a brake mechanism and a hub reduction part mechanism. The axle housing mechanism comprises an axle housing assembly; the main reduction mechanism comprises a main reduction shell assembly and a limited slip differential assembly. The brake mechanism comprises a wet brake assembly; the hub reduction mechanism comprises a hub assembly, a half shaft assembly, a first-stage planetary transmission assembly, a second-stage planetary transmission assembly and a gear ring supporting assembly. The same piston is adopted for traveling braking and parking braking, the braking safety is improved, the wet brake adopts an independent lubricating box body and a heat dissipation system, and the high temperature generated by braking sliding friction is effectively reduced; under the large-load working condition, lubricating pressure oil of the brake is effectively prevented from entering the axle housing, and sealing is more efficient; a lubricating oil exchange system of a main reducer and a wheel edge is provided with a wheel edge efficient self-lubricating system, a lubricating oil flowing path is designed in a planet row according to a lubricating flow field analysis result, and the requirement for large lubricating flow of the needle bearing is met.

    本发明公开一种行驻一体湿式制动驱动桥,包括:桥壳机构、主减机构、制动机构、轮边减速部机构;桥壳机构包括:桥壳总成;主减机构包括:主减壳体总成,限滑差速器总成;制动机构包括:湿式制动器总成;轮边减速机构包括:轮毂总成、半轴总成、一级行星传动组件、二级行星传动组件和齿圈支撑总成;行车制动和驻车制动采用同一个活塞,提高了制动的安全性,湿式制动器采用独立的润滑箱体和散热系统,有效降低制动滑摩产生的高温;在大载荷工况下,有效防止制动器的润滑压力油进入桥壳中,密封更加高效;主减和轮边的润滑油交换系统具有轮边高效自润滑系统,根据润滑流场分析结果,在行星排中设计润滑油流动路线,满足滚针轴承大润滑流量的需求。
