Description

Technical Field

[0001] The present invention belongs to the technical field of traction, and more specifically, relates to a traction device and a railway vehicle. Background Art

[0002] Railway flat cars are mainly used for railway line construction, maintenance, and transportation of rails, electrified railway contact network materials, equipment and maintenance tools. They are one of the main equipment for railway construction. There are many types of existing railway flat cars in China, all of which are underframe load-bearing structures. The underframe is mainly composed of a center beam, side beams, end beams, sleeper beams and other structures. The end structure of the center beam is called a "traction beam". The design of the traction beam structure directly affects the vehicle's coupler height (the distance between the center line of the coupler and the rail surface).

[0003] At present, the traction beam structure of existing flat cars in China is mainly made of fish belly type with full-length steel, which meets the requirement of 880mm coupler height and can be combined with domestic electric locomotives or other types of existing freight cars to meet the needs of marshaling. This traction beam structure meets the needs of domestic coupler height, but cannot meet the coupler height required by special household groups or the coupling requirements with other national railway locomotives and freight cars.

[0004] In a flat car development project hosted by our company, the flat car was used by a Chinese enterprise in foreign railway construction. The foreign user provided an electric locomotive to pull the car (the coupler height was 585mm). The train formation was as follows: the traction beam in the domestic standard center beam composition was used to connect the flat cars (the coupler height was 880mm), but both ends of the car group needed to be connected to a foreign locomotive (the coupler height was 585mm). This formation method would cause a problem. In the end car, the coupler height at one end was 585mm, and the coupler height at the other end was 880mm, that is, two coupler heights were required in one flat car, that is, two traction beam structures were required in one flat car. In order to solve the problem of connecting with foreign locomotives, a traction device that matches the coupler height of foreign locomotives needed to be designed. Summary of the invention
