H-shaped coupler assembly and rail vehicle

Abstract

The invention discloses an H-shaped coupler assembly and a rail vehicle. The H-shaped coupler assembly comprises a coupler, a buffer device, a steering body and a joist device. A vertical pin penetrating hole' is formed in a connecting rod of the coupler, a transverse pin penetrating hole' is formed in one end of the buffer device, and a transverse pin penetrating hole and a vertical pin penetrating hole which are mutually perpendicular are formed in the steering body. Transverse pins are arranged in the transverse pin penetrating hole and the transverse pin penetrating hole' simultaneously ina penetrating mode, thus the buffer device and the steering body are rotationally connected, and the steering body can swing in the perpendicular plane relative to the buffer device so as to meet thevibrating need of the rail vehicle and the need of the rail vehicle for passing through a vertical curve. Vertical pins are arranged in the vertical pin penetrating hole and the vertical pin penetrating hole' simultaneously in a penetrating mode, thus the coupler and the steering body are rotationally connected, and the coupler can swing in the horizontal plane relative to the steering body so asto meet the need of the rail vehicle for passing through a horizontal curve. The H-shaped coupler assembly belongs to a tight-lock coupler assembly, the vertically-allowed moving distance of the H-shaped coupler assembly is small, great anti-abrasion performance is achieved, thus abrasion of the coupler is reduced, and the service life of the coupler is prolonged.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to an H-shaped coupler assembly and a rail vehicle. Background technique [0002] Due to the poor road conditions of the Myanmar Railway, the No. 15 automatic coupler, which is well used on my country's large railway passenger cars, suffered serious wear and tear soon after it was used in Myanmar. Generally, it will wear out after about half a year of use, especially the S surface of the No. 15 coupler knuckle. The reason analysis is that after the No. 15 coupler is connected, there are no constraints in all directions, and it is easily affected by vehicle load changes and vibrations. There will be a certain distance of relative movement between the connecting surfaces of the two couplers, resulting in friction and wear. When the condition of the line is bad, this vertical motion will be more frequent and the amplitude will be larger, thereby increasing the wear and tear of th...

Problems solved by technology

The reason analysis is that there is no constraint in all directions after the No. 15 coupler is connected, and it is easily affected by vehicle load changes and vibrations. There will be a certain distance of relative movement between the connecting surfaces of the two couplers, resulting in friction and wear.

When the condition of the line is bad, this vertical movement will be more frequent and the amplitude will be larger, which will increase the wear of the coupler
