Abstract
The utility model discloses a reinforcement device for an automobile forecabin. The reinforcement device for the automobile forecabin comprises connecting plates (1) and a connecting rod (2). The number of the connecting plates (1) is two, and the connecting plates (1) are respectively installed at two ends of the connecting rod (2). Besides, the connecting plates (1) are installed in a left-and-right symmetry mode, and the connecting plates (1) and the connecting rod (2) are in an integrated structure. Punch forming is adopted in the connecting plates (1), and the surfaces of the connecting plates (1) are attached to a shock absorber of the automobile forecabin, and the connecting plates (1) are directly installed on the shock absorber through bolts. The end portion of the connecting rod (2) and the connecting plates (1) are welded together by carbon-dioxide arc welding. The reinforcement device for the automobile forecabin with the above special structure is connected onto a left-and-right shock absorber seat through the device, a left region and a right region of the forecabin can be effectively connected together, structure is simple, occupied space is small, and appropriate materials and thicknesses are selected through finite element analysis and experimental verification. The reinforcement device for the automobile forecabin can effectively improve the torsional rigidity of an automobile body, and accordingly the service life is prolonged.
Description
Technical field
The utility model relates to a kind of stiffening device for automobile front chamber.
Background technology
The torsional stiffness of vehicle body has direct impact as the important mechanical property of vehicle body to the performance of car load each side, and good body torsional rigdity not only can improve the NVH performance of car load, and the life-span of automobile is also had greatly improved.The automobile that torsional stiffness is relatively poor is subject to External Force Acting and tends to occur vehicle body left and right twisting or regional area large deformation when road traveling, long duration of action expendable plastic deformation can occur and even rupture.
At present automobile in the front deck design, often adopts a large amount of loaded down with trivial details designs to promote torsional stiffness, performance difficulty on technique not only, and can gain in weight.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of stiffening device for automobile front chamber for problems of the prior art, its objective is the torsional stiffness that obviously improves vehicle body integral body under the prerequisite that adds vehicle body weight that as far as possible reduces.
The technical solution of the utility model is that the stiffening device that this kind is used for automobile front chamber comprises connecting panel and pipe link, and described connecting panel has two, be arranged on respectively the two ends of pipe link, and the connecting panel left-right symmetric is installed; Described connecting panel and pipe link are the integral type structure, and connecting panel employing punch forming, and the surface of connecting panel and the bumper of automobile front chamber are fitted, and are directly installed on bumper by bolt.
Described pipe link adopts the rolling technology moulding.
The cross section of described pipe link is square or circular.
The end of described pipe link and connecting panel pass through the carbon-dioxide arc welding weld together.
The stiffening device that this kind with said structure is used for automobile front chamber has the following advantages:
1. this kind is connected to the left and right damper base for the stiffening device of automobile front chamber by this device, zone, front deck left and right effectively can be coupled together, and is simple in structure, takes up room little.
2. this kind is used for stiffening device process finite element analysis and the verification experimental verification of automobile front chamber, selects suitable material and thickness, and this device can improve the torsional stiffness of vehicle body by actv., and then promotes its service life.
Description of drawings
Below in conjunction with accompanying drawing, utility model is described further:
Fig. 1 is the structural representation of utility model.
In Fig. 1,1: connecting panel; 2: pipe link.
The specific embodiment
By structure shown in Figure 1 as can be known, the stiffening device that this kind is used for automobile front chamber comprises connecting panel 1 and pipe link 2, and connecting panel 1 has two, is arranged on respectively the two ends of pipe link 2, and connecting panel 1 left-right symmetric is installed; Connecting panel 1 is the integral type structure with pipe link 2, and connecting panel 1 employing punch forming, and the surface of connecting panel 1 and the bumper of automobile front chamber are fitted, and are directly installed on bumper by bolt.
The stiffening device that this kind is used for automobile front chamber is connected to the left and right damper base by this device, zone, front deck left and right effectively can be coupled together, and is simple in structure, takes up room little; Through finite element analysis and verification experimental verification, select suitable material and thickness, this device can improve the torsional stiffness of vehicle body by actv., and then promotes its service life.
