Outer pillow structure of rail vehicles

Abstract

The outer structure of the rail vehicle in the present invention, the lower cover plate of the corbel is fixed with a center disc seat by bolts, the rear end of the traction beam is welded to the corbel, the interface of the bogie is placed between the two webs of the corbel, and the center disc seat on both sides Mounting holes are arranged on the lower cover of the corbel; the front section of the traction beam is provided with a coupler mounting seat, and a large crossbeam is arranged transversely between the traction beam and the side beam, and the large crossbeam is located near the coupler mounting seat. A corrugated floor is laid, a flat floor is laid between the large beam and the end beam, a flat plate is laid on the upper surface of the traction beam, and the front end of the traction beam is a trumpet structure. Through a series of improvements and designs, the outer pillow structure of the present invention realizes high load capacity, low maintenance, simple manufacture, and small curve radius, which can well adapt to the operating characteristics of meter-gauge intercity buses.

Description

technical field [0001] The invention relates to the end structure of the underframe of a rail vehicle, and is especially suitable for the outer structure of the underframe of a meter-gauge intercity passenger car, and belongs to the field of car body steel structure design. Background technique [0002] 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. How to better meet the operating environment of foreign lines is of great significance to the development of international markets. 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. [0003] Meter-gauge railway is a commonly used track in the world. Meter-gauge intercity passenger cars often adopt the design concept of narrow car width and short ca...

Problems solved by technology

However, such a design greatly squeezes the distance from the bolster to the end of the car, which brings difficulties to the bearing capacity of the structure outside the bolster, the interface layout between the chassis and the coupler, and the avoidance of the car body and the bogie.
