The invention relates to the technical field of electric locomotives and diesel locomotives, in particular to a traction device. The traction device comprises a traction base, a connecting beam, a traction rod mechanism, a traction pin, a conical rubber joint, a press plate, a concave spherical joint, a convex spherical joint, a joint cover, an oil cup, a bush, a connecting pin, a liner and a connecting beam installing base. The traction base is connected with the connecting beam through the connecting pin, the traction base is connected with the traction pin on a framework traction beam through the press plate, the concave spherical joint and the convex spherical joint which are connected are connected on the traction rod mechanism, two ends of the traction rod mechanism are connected with the connecting beam and a locomotive body traction installing base respectively, and the connecting beam installing base is connected with the traction rod mechanism through a connecting pin. By means of the traction device, traction of a bogie to the locomotive body within a short distance can be achieved, vertical vibration displacement between the locomotive body and the bogie can be relieved effectively, design of connection of the bogie and the locomotive body is flexible, and different lengths can be designed according to different requirements.
Description
technical field [0001] The invention relates to the technical field of electric locomotives and internal combustion locomotives, in particular to a traction device. Background technique [0002] The drawbar device is a component that transmits traction and braking forces between the bogie and the car body. The original traction device has a complex structure, consisting of two drawbars, two crank arms, a connecting rod, multiple pins, sleeves, and joint bearings. etc., the whole drawbar device is connected to the frame by two pins at the crank arm, one end of the drawbar is connected to the crank arm, the other end is connected to the vehicle frame, and the two crank arms are connected by a connecting rod. The crank arm assembly is arranged under the side beam of the frame, which requires high space and is difficult to arrange. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a traction device. [0004] The...
