The invention relates to a rear axle steering device and a steering system thereof. The rear axle steering device comprises an axle I-shaped beam, a steering knuckle body, a steering machine assembly, a steering drag link and a control assembly, and the steering knuckle body is hinged to the axle I-shaped beam; the steering engine assembly comprises a steering engine body and a connecting piece, the steering engine body is arranged on the axle I-shaped beam, and the connecting piece is connected with the steering engine body; one end of the steering drag link is movably connected to the connecting piece, the other end of the steering drag link is connected with the steering knuckle body, and the steering drag link is configured as follows: one end of the steering drag link moves along the length extension direction of the connecting piece, and the other end drives the steering knuckle body to rotate relative to the axle I-beam; the control assembly comprises a control unit, the control unit is connected with the steering engine body, and the control unit is used for outputting a steering angle target value according to the steering angle value of the front axle steering assembly and controlling the steering engine body to execute according to the steering angle target value. According to the invention, the pure electric steering engine assembly is adopted to replace an original electro-hydraulic steering engine, so that the types of parts are greatly reduced.
