Front auxiliary frame mounting bracket assembly structure of fuel cell hydrogen energy automobile

Abstract

The invention provides a front auxiliary frame mounting bracket assembly structure of a fuel cell hydrogen energy automobile. The front auxiliary frame mounting bracket assembly is connected with a front longitudinal beam through carbon dioxide arc welding, and comprises a front auxiliary frame mounting bracket, a mounting bracket right side reinforcing plate, a mounting bracket supporting piece and a mounting bracket left side reinforcing plate. The front auxiliary frame mounting bracket, the mounting bracket right side reinforcing plate, the mounting bracket supporting piece and the mountingbracket left side reinforcing plate are connected through carbon dioxide arc welding. The front auxiliary frame mounting bracket assembly is connected with the front longitudinal beam through carbondioxide arc welding. The requirements of new energy light buses for strength, light weight and cost can be met, a production line is simplified, and the cost of the production line is low.

Description

technical field [0001] The invention relates to the technical field of automobiles and parts, in particular to a mounting bracket assembly structure for a front sub-frame of a fuel cell hydrogen energy automobile. Background technique [0002] Generally speaking, due to the high development cost and long development cycle of chassis sub-frame and other components, in order to reduce the development cost, cycle and risk of the whole vehicle, the borrowing of chassis sub-frame is usually given priority, that is, from the existing mature product library Make adaptive choices. However, in order to consider the versatility of the product, the main structure of the borrowed parts cannot be changed, and can only be matched and adjusted through the body, which often leads to problems such as too long and too high cantilever at the chassis mounting point, and it is difficult to guarantee the rigidity and strength of the chassis mounting point. [0003] New energy light buses have hi...

AI Technical Summary

Problems solved by technology

Since the front sub-frame is a borrowed part, the main structure cannot be changed, so the length of the cantilever at the chassis installation point is affected by the layout of the chassis, and it is generally difficult to reduce

[0004] The traditional front sub-frame mounting bracket structure is a stamping part, the mold cost is high, the weight is heavy, and the strength is not easy to guarantee, which does not meet the strength, light weight and cost requirements of new energy light vehicles
