Abstract:
Disclosed is a shock absorption mechanism of a steering motor, comprising an upper cover buffering assembly (1), and an oil distributor (2) disposed below the upper cover buffering assembly (1), the oil distributor (2) being fitted with the upper cover buffering assembly (1) to form a sealed axial cavity (4). A cylinder assembly (5) is fixedly arranged below the oil distributor (2). The cylinder assembly (5) comprises a cylinder (51) opened at both ends, and an elastic oil bag (52) arranged in the cylinder (51) and having an opening at the upper end, the upper end of the elastic oil bag (52) being fixedly connected to an inner wall of the cylinder (51), and the upper end of the elastic oil bag (52) being in communication with the axial cavity (40). The cylinder (51) is further provided internally with a piston (53) axially sliding along the cylinder (51), the piston (53) being connected to the lower end of the elastic oil bag (52). The shock absorption mechanism for a steering motor overcomes the problem of member damage due to friction and the defect of susceptibility to temperature in a traditional hydraulic shock absorption system, so as to prolong the service life of the shock absorption mechanism.
