The invention discloses a hydraulic plate trailer drive axle which comprises a combined axle shaft, a motor, hubs, a steel ring, a tire and a connecting flange, the two ends of a hollow shaft of the combined axle shaft are connected with the hubs through hub bearings respectively, the hubs, the steel ring and the connecting flange are fixedly connected, the tire is connected to the steel ring in a sleeving mode, and the motor comprises a shell, a stator, an oil distribution shaft and a plunger. The oil distribution shaft, the stator and the shell are sequentially connected from inside to outside in a sleeved mode, the shell is connected to the connecting flange, the inner surface of the shell is a curved surface, a plurality of plunger grooves are formed in the outer surface of the stator in the circumferential direction, one plunger is arranged in each plunger groove, an oil distribution shaft oil inlet channel and an oil distribution shaft oil outlet channel are formed in the oil distribution shaft, and hydraulic oil flows through the oil distribution shaft oil inlet channel and the oil distribution shaft oil outlet channel along with rotation of the oil distribution shaft and the shell. The plunger grooves are alternately communicated with the oil distribution shaft oil inlet channel and the oil distribution shaft oil outlet channel. The hydraulic oil drives the motor shell to rotate forwards and backwards, the wheels are driven to move forwards and backwards, the power torque of the vehicle body is adjustable, the bearing capacity is large, operation is flexible, slow driving can be achieved, and the vehicle is suitable for equipment carrying under severe road conditions.

    本发明公开了一种液压板车驱动桥,包括组合桥轴、马达、轮毂、钢圈、轮胎、连接突缘,组合桥轴的空心轴两端各通过轮毂轴承连接轮毂,轮毂、钢圈、连接突缘固定连接,轮胎套接在钢圈上,马达包括壳体、定子、配油轴和柱塞,配油轴、定子、壳体从内到外依次套接,壳体连接在连接突缘上,壳体内表面为曲面,定子外表面周向设有多个柱塞槽,每个柱塞槽内一个柱塞,配油轴上设有供液压油流过的配油轴进油道和配油轴出油道,随着配油轴和壳体的转动,柱塞槽交替连通配油轴进油道和配油轴出油道。本发明通过液压油驱动马达壳体正向和反向转动,带动车轮前进和后退,车体动力扭矩可调、承载大、运行灵活机动、可缓速驱动,适用恶劣路况的设备运载。
