Rail vehicle and coupler mounting assembly thereof

Abstract

The invention discloses a coupler mounting assembly applied to rail vehicles, which comprises a coupler box body and a mounting seat; and also includes stopper seats fixed on both sides of the coupler box body and extending along the length direction of the coupler box body; The block seat is located at the front end of the mounting seat; the coupler body support plate is located on the mounting seat and abuts against the stop seat to limit the movement toward the forward direction of the rail vehicle; it is fixed on both sides of the coupler box body and along the side of the coupler box body. The limit block extending in the length direction; the limit block is located at the rear end of the mounting seat; the stop block is slidably connected with the limit block and is abutted against the coupler support plate; the stop block can move along the coupler box relative to the limit block The length direction of the main body moves within a certain range, and the stop block and the stop seat are respectively located at the rear end and the front end of the support plate of the hook body. The invention also discloses a rail vehicle including a coupler mounting assembly. The above-mentioned coupler mounting assembly can effectively avoid the failure of the coupler caused by the shearing of the mounting bolts.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a rail vehicle and a coupler installation assembly thereof. Background technique [0002] In the current rail vehicle technology, according to the requirements of relevant standards, the current multi-type coupler installation device for rail vehicles, the chain hook mounting seat is designed on the lower cover of the coupler box, and the blind hole thread is designed on the chain hook mounting seat according to the position of the chain hook mounting bolt. , and design the position of the chain hook stop seat according to the blind hole thread, the chain hook stop seat and the mounting seat constitute the chain hook installation structure. The above-mentioned chain hook mounting structure can withstand a certain compressive load, which is mainly realized by shearing of the chain hook mounting bolts. [0003] According to the standard of BS EN 15020-2006+A1-2010 "Railway F...

Problems solved by technology

[0003] According to the standard of BS EN 15020-2006+A1-2010 "Railway Facilities—Rescue Coupler—Performance Requirements, Special Connector Geometric Dimensions and Test Methods", when a vehicle fails, it needs to be rescued, and the vehicle is towed in the rescue condition. The device needs to withstand a compressive load of 300KN, but the chain hook and installation structure based on the UIC standard do not have the performance to withstand a compressive load of 300KN. The shearing will lead to the failure of vehicle rescue, and may cause irreversible damage to the car body, coupler box and other parts
