Hydraulic motor with one-way locking function

The hydraulic motor with the one-way locking function comprises a motor front cover, a motor rear cover, a stator and a rotor assembly connected with a rotating shaft, one end of the rotating shaft is connected with a brake device, the brake device comprises a transmission shaft, a circle of brake protrusions extending in the opposite direction are arranged on the outer side of the transmission shaft in a surrounding mode, and the rotor assembly is connected with the motor rear cover. The fixing cavities are formed between the inner walls and the outer walls of every two adjacent brake protrusions, and the driving devices control the heads of the pawls to be inserted into or moved out of the fixing cavities; when the head of the pawl is inserted into the fixing cavity and the transmission shaft rotates reversely, the pawl is locked by the fixing cavity and cannot rotate; the one-way locking device has the advantages that the one-way locking function of the hydraulic motor is achieved through cooperation of th
