The invention discloses an electrically-controlled hydrostatic high-speed-ratio high-torque wet brake drive axle which comprises an axle body, hub belt wet brake assemblies are arranged at the left end and the right end of the axle body, the axle body and the hub belt wet brake assemblies are integrally cast, and a multi-stage speed reducer assembly is arranged in the middle section of the top of the axle body. Half shafts are arranged on the two sides, facing the hub belt wet brake assembly, in the axle body, the multi-stage speed reducer assembly comprises a three-stage speed reducer shaft, a second-stage speed reducer shaft is arranged at the top of the three-stage speed reducer shaft, and a first-stage speed reducer shaft is arranged at the top of the second-stage speed reducer shaft; according to the device, the axle body and the hub belt wet brake assembly are integrally cast, the structural design is simple and compact, the casting difficulty is greatly reduced, meanwhile, the machining cost is reduced due to the reduction of machining die investment, a floating oil seal structure is omitted, potential quality hazards caused by oil leakage are greatly reduced, and the service life of the device is prolonged. And the size is small while the mechanical traction performance is kept, so that the power density is improved, and the energy consumption is reduced.
本发明公开了一种电控静液压型大速比高扭矩湿式制动驱动桥,包括桥体,桥体的左右两端均设置有轮毂带湿式制动器总成,桥体和轮毂带湿式制动器总成一体铸成,桥体的顶部中段设置有多级减速器总成,桥体的内部朝向轮毂带湿式制动器总成的两侧均设置有半轴,多级减速器总成包括有三级减速器轴,三级减速器轴的顶部设置有二级减速器轴,二级减速器轴的顶部设置有一级减速器轴;本装置利用了桥体和轮毂带湿式制动器总成一体铸成等,结构设计简洁、紧凑,铸造难度也大幅下降,同时,加工模具投入减少导致了加工成本的下降,并减少了浮动油封结构,大大降低了因漏油导致的质量隐患,且在保持机械牵引性能的同时尺寸较小,从而提高动力密度,降低能耗。
