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.
