Abstract

The invention provides a vehicle front subframe, a front suspension bracket and a vehicle. The front subframe comprises: front subframe upper plate, front subframe lower plate, front mounting seat, rear mounting seat, rear suspension front mounting seat, rear mounting rear mounting seat, left connecting strut, right connecting strut, left swing arm mounting plate, right swing arm mounting plate, steering gear mounting seat, triangular swing arm mounting seat and stabilizer bracket mounting seat; Front mounting seat, rear mounting seat, rear suspension front mounting seat, rear suspension rearmounting seat, steering gear mounting seat, triangular swing arm mounting seat and stabilizer bracket mounting seat all adopt pipe string structure. As that upper plate of the front subframe and the low plate of the front subframe are welded into the main body of the front subframe of the vehicle, each mount point is welded on the main body of the front subframe of the vehicle, and each mounting seat adopts a pipe string structure, the lightweight of the front subframe of the vehicle is realize, and the problem of low welding precision between the front subframe of the vehicle and other partsis solved.

Description

technical field [0001] The invention relates to automobile manufacturing technology, in particular to an automobile front auxiliary frame, a front suspension bracket and an automobile. Background technique [0002] In the car chassis system, the sub-frame of the car is a very important part of the car chassis as a support for the front and rear axles and suspension. The sub-frame of the car is the skeleton of the front and rear axles. The axle and suspension are connected to the "main frame" through the sub-frame, so that the suspension becomes an assembly part. As a part of the sub-frame of the car, the front sub-frame is installed on the body, which can provide mounting points for steering gear, stabilizer bar, swing arm, engine suspension and other components. [0003] At present, the front subframe of automobiles is usually welded by multiple sheet metal stamping parts. At the same time, due to the four-point suspension structure of the engine, the front subframe is usu...
