The invention discloses an integrated hydraulic drive axle with a differential mechanism and a static braking function. The hydraulic drive axle comprises a central shell used for bearing main loads, an oil port is formed in the top of the central shell, and the hydraulic drive axle is provided with a structure of a mounting trunnion flange, a steering oil cylinder and a low-speed large-torque motor assembly. A motor cavity and a differential mechanism cavity are formed in the central shell; supporting arms are arranged at the two ends of the central shell; the low-speed large-torque motor torque assembly is arranged in the motor cavity; an oil distributor is further arranged at one end of the torque assembly of the low-speed large-torque motor and plays a role in distributing oil for the torque assembly of the low-speed large-torque motor. The low-speed large-torque motor is directly driven, a reduction gearbox and a bevel gear are omitted, the transmission route is simplified, gear transmission defects are reduced, and the transmission precision is improved; a transmission structure is simplified, the number of total parts is reduced, the cost is reduced, and the assembly manufacturability is improved; and the design of modular parts provides a more flexible selection scheme for a user.
本发明公开了一种具有差速机构和静态制动功能的一体式液压驱动桥,该液压驱动桥包括用于承受主要负载的中央壳体,顶部设置有油口,自身具有安装耳轴法兰、转向油缸、低速大扭矩马达组件的结构;在中央壳体内部形成有马达腔体与差速器腔体;且在中央壳体的两端均设置有支撑臂;低速大扭矩马达扭矩组件,置于马达腔体内;在低速大扭矩马达扭矩组件的一端处还设置有配油器,起给低速大扭矩马达扭矩组件配油的作用;低速大扭矩马达直接驱动,取消了减速箱和锥齿轮的使用,简化了传动路线,减少齿轮传动缺陷,提高传动精度;简化传动结构,减少总零部件数量,降低成本,提高装配工艺性;模块化零件的设计为用户提供更灵活的选择方案。
