Description
Technical field
The utility model relates to the Rear secondary frame for vehicle of automobile.
Background technology
In recent years, it is more and more general that back suspension on intermediate car adopts independent suspension to substitute semi-independent suspension, along with people to the improving constantly and continuous advancement in technology of car traveling comfort, safety, handling requirement, increasing back suspension type emerges.Adopting H type structure Lower control arm, is exactly to hang after a kind of later-model many connecting rods form at present by suspension type prenex and flare connecting rod control four-wheel orientation angle simultaneously.This rear-mounted version more complicated all has higher requirements to technical indexs such as structural modal, rigidity, intensity, and existing in the market Rear secondary frame for vehicle can't be applicable to such suspension.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of Rear secondary frame for vehicle that is applicable to many connecting rods rear suspension.
The technical scheme that the utility model adopted is: a kind of Rear secondary frame for vehicle, comprise front-axle beam, the back rest, be connected Zuo Liang and You Liang between the front-axle beam and the back rest, preceding Lower control arm left socle and preceding Lower control arm right support, the front-axle beam and the back rest are hollow structure, preceding Lower control arm left socle and preceding Lower control arm right support include front side plate and rear quarter panel, before the preceding Lower control arm left socle, back both sides are respectively equipped with first brace panel and second brace panel, first brace panel is welded on the front side plate of the diapire of front-axle beam and preceding Lower control arm left socle, and second brace panel is welded on the rear quarter panel of the diapire of left beam and preceding Lower control arm left socle; The forward and backward both sides of preceding Lower control arm right support are respectively equipped with the 3rd brace panel and the 4th brace panel, the 3rd brace panel is welded on the front side plate of the diapire of front-axle beam and preceding Lower control arm right support, and the 4th brace panel is welded on the rear quarter panel of the diapire of right beam and preceding Lower control arm right support.
Rear secondary frame for vehicle of the present utility model has adopted the frame-type structure, on preceding Lower control arm support and in the front-axle beam and the back rest, all set up brace panel, thereby improved rigidity, structural modal and the intensity of product, made the utility model be applicable to and cooperate many connecting rods rear suspension to use.
