Railway vehicle chassis end structure

Abstract

The invention relates to a railway vehicle chassis end structure which comprises an end beam, a traction beam and a corrugated floor. An unhooking protection device and a tripping prevention impact seat are arranged on the end beam, angle steel is arranged on the rear portion of the end beam and connected with the corrugated floor in a welded mode, a ribbed plate is welded to the portion between the end beam and the angle steel, connecting plates are further welded to protective cases of the unhooking protection device, and the connecting plates are welded to the traction beam. According to the railway vehicle chassis end structure, the angle steel splicing welding structure is adopted by the end beam, the relation between the end beam and a welding connector of the corrugated floor is optimized, and the situation that the corrugated floor structure is adopted by vestibules is achieved; the structure is simpler, and manufacture is convenient. By means of the novelly designed impact seat, the problem of interference with a diaphragm windshield frame can be solved, and the situation that a draw gear jump upwards and cracks up windshield aluminum profile can be effectively prevented. The unhooking protection device can effectively pulls a vehicle to a nearby maintenance point under the condition of unhooking.

Description

technical field [0001] The invention relates to an end structure of a rail vehicle underframe, and belongs to the technical field of the end structure design of an underframe of a rail vehicle. Background technique [0002] Railway intercity passenger trains operate frequently and have a large passenger capacity. They are one of the most important tools to guide passengers on main lines and branch lines. After entering the 21st century, countries around the world continue to increase railway construction, bringing unprecedented business opportunities to the export of domestic railway passenger cars. However, the existing structure in China cannot meet the platform and boundary conditions of existing intercity lines abroad. Designing an intercity bus that can meet the existing line conditions, has a strong carrying capacity, and has high safety can effectively improve the operating efficiency of intercity buses and relieve the travel pressure of passengers. [0003] The int...

AI Technical Summary

Problems solved by technology

[0003] The intercity bus has a large passenger capacity, and the corrugated floor is generally used outside the pillow to improve the vertical rigidity. However, considering the interface relationship between the corrugated floor and the end beam, the flat floor is generally used at the platform, and the structure of the reinforcing beam is used below, but The similar structure is relatively complex, and the manufacturing process is relatively cumbersome

In foreign lines, the platform may be low and the coupler height may be high, which will lead to interference between the impact seat and the bellows windshield commonly used in China.
