Abstract

The invention provides a sleeper beam and a vehicle with the same. The sleeper beam comprises a sleeper beam body, the sleeper beam body is arranged between a bodywork and a bogie so that the bogie can be connected with the bodywork through the sleeper beam body, the sleeper beam body comprises multiple splicing parts, the splicing parts are sectional materials, the sectional materials are sequentially spliced in the width direction, and the cross section of the splicing parts is shaped like the Chinese character 'tian'. By means of the sleeper beam, the problem that the strength and stabilityof a sleeper beam in the prior art are poor is solved.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a corbel and a vehicle with the same. Background technique [0002] With the development of the rail transit industry, high-speed EMUs are developing in the direction of faster, safer, more reliable, more energy-saving and more efficient. While the speed of the train is increasing, higher requirements are placed on the stability of the traction system. How to ensure the efficient, smooth and reliable transmission of traction power to the entire EMU is a direction that the rail transit industry needs to continue to study. [0003] As a key component connecting the car body and the bogie, the bolster is responsible for transmitting longitudinal compression and traction to the car body. It is a power transmission hub and needs to withstand long-term vibration and shock. It is subjected to large stress loads and is the main force-bearing part of the car body. [0004] Existing aluminum alloy...
