Platformization front auxiliary frame

Abstract

The invention provides a platform front auxiliary frame which comprises a front auxiliary frame body, the front auxiliary frame body comprises a bottom plate, a front upper plate, a rear upper plate, a left upper plate and a right upper plate, the front upper plate and the bottom plate are welded to form a front cross beam, the rear upper plate and the bottom plate are welded to form a rear cross beam, the left upper plate and the bottom plate are welded to form a left longitudinal beam, and the right upper plate and the bottom plate are welded to form a right longitudinal beam. And the front upper plate, the rear upper plate, the left upper plate and the right upper plate enclose to form a groove for accommodating the steering engine at the center of the bottom plate. According to the platformization front auxiliary frame, the front auxiliary frame body is formed by welding the bottom plate and the four upper plates, and compared with a design mode that a traditional structure is formed through sheet metal part draft forming, the maximum space can be formed in a limited space range for avoiding a steering engine to be placed; the connection mode is more beneficial to arrangement of all parts of the chassis and the front cabin, upgrading and derivation between vehicle models can be achieved, and the research and development time and cost of new vehicle models are saved.

Description

technical field [0001] The invention relates to the technical field of automobile chassis, in particular to a platformized front auxiliary frame. Background technique [0002] With the increasingly fierce competition among domestic automobile brands, customers have higher and higher requirements for automobile quality. How to provide more and higher-quality models with limited R&D funds is an urgent problem for automotive R&D personnel to solve. In the process of automobile research and development, each new model needs to re-develop a new chassis structure, in which the front sub-frame is an important part of the chassis component system. It is mainly connected to parts such as body, engine mount and suspension, which can reduce the vibration of the road surface and the transmission of noise and other excitations to the body. At the same time, it can also improve the stiffness of the suspension, so that the body can obtain better comfort and stability. Therefore, in the r...
