Disclosed is a steering motor, comprising a spring damping valve, and an oil distributor which is fitted with the spring damping valve to form a cavity in which a buffering assembly is provided. A cylinder assembly is provided on a lower side of the oil distributor, and comprises a cylinder, an elastic oil bag provided in the cylinder, and a piston which is provided in the cylinder and fixedly connected to the elastic oil bag, the piston being capable of sliding axially along the cylinder. In addition, the oil distributor is further provided with an oil flow passage; the spring damping valve protrudes out of a hollow column having an inner cavity; a directional control valve having a valve core is inserted in the cavity of the hollow column; the hollow column is further provided with an oil flow port in communication with the oil flow passage; an oil inlet groove is provided on and in communication with the oil flow port; and the valve core protrudes into the hollow column and is fitted with the oil flow port and the oil inlet groove. The steering motor adopts an oil passage combination design to simplify the structure, and also adopts the elastic oil bag to reduce the frictional wear of a shock absorption mechanism, so as to prolong the service life of steering motor and reduce the costs.
