The invention discloses a traction device which comprises a traction base with a center hole, a center pin base connected with an automobile body. A center pin is installed on the center pin base, thelower end of the center pin stretches out of the center pin base, and the lower end of the center pin and the traction base are assembled through an axle hole; blind holes are formed in the two sidesof the longitudinal direction of the traction base in the longitudinal direction, and steel springs are arranged inside the blind holes. The traction device and a bogie are simple in structure and reasonable in design, and the special requirements for longitudinal traction, rotation flexibility and the like of the bogie and the automobile body are met. By adopting the mode that the steel springsare matched with traction stop blocks, due to the excellent linear rigidity performance steel springs, the comfort of the automobile can be improved, and the traction device has the longer service life. Due to the installation layout structure of an anti-crawling shock absorber, the problem that the overtaking limit is caused when the anti-crawling shock absorber is arranged on a frame side beam can be solved, and the structure compactness of the bogie can be improved.
