Reinforcing device for front compartment of automobile

Abstract

The invention discloses a reinforcing device for a front compartment of an automobile. The reinforcing device comprises connecting plates (1) and a connecting rod (2), wherein two connecting plates (1) are arranged and respectively mounted at the two ends of the connecting rod (2); the two connecting plates (1) are mounted in a bilaterally symmetric way; the connecting plates (1) and the connecting rod (2) are an integrated structure; the connecting plates (1) are molded through stamping; the surfaces of the connecting plates (1) are laminated with a shock absorber of the front compartment of the automobile and directly mounted on the shock absorber through bolts; and the end part of the connecting rod (2) is welded together with the connecting plates (1) through carbon-dioxide shielded welding. As the reinforcing device for the front compartment of the automobile, which has the special structure, is connected to a left shock absorber seat and a right shock absorber seat, a left area and a right area of the front compartment are effectively connected with each other and simple structure and less space usage are achieved; through finite element analysis and experimental verification, the torsional rigidity of a vehicle body can be effectively enhanced by selecting proper materials and thickness, so that the service life of the vehicle body is further prolonged.

Description

technical field [0001] The invention relates to a reinforcement device for the front cabin of an automobile. Background technique [0002] As an important mechanical property of the car body, the torsional stiffness of the car body has a direct impact on the performance of all aspects of the vehicle. Good torsional stiffness of the car body can not only improve the NVH performance of the car, but also greatly improve the life of the car. Cars with poor torsional rigidity will often twist from side to side or undergo large deformation in local areas when they are subjected to external forces when driving on the road. After long-term action, there will be irreversible plastic deformation or even fracture. [0003] At present, in the design of the front cabin of automobiles, a large number of cumbersome designs are often used to improve the torsional rigidity, which is not only difficult to implement in terms of technology, but also increases the weight.
