Abstract
The invention discloses an automobile fore-cabin reinforcing device which comprises two connecting plates (1) and a connecting bar (2), wherein the two connecting plates (1) are respectively arranged on two ends of the connecting bar (2), and the connecting plates (1) are left and right symmetrically arranged, the connecting plates (1) and the connecting bar (2) are separated, and the connecting plates (1) are punched, the surfaces of the connecting plates (1) are fit with dampers of a fore-cabin of an automobile, the connecting plates are directly arranged on the dampers through bolts, and the end part of the connecting bar (2) is welded to the connecting plates (1) through carbon-dioxide arc welding. The automobile fore-cabin reinforcing device with the special structure is connected to left and right damper seats so that the left and right areas of the fore-cabin can be effectively connected, and has the advantages of simple structure and small occupation space; and according to the automobile fore-cabin reinforcing device, through finite element analysis and experimental verification, appropriate materials and thicknesses are selected, thus the torsional rigidity of the automobile body can be effectively improved, and then the service life of the automobile is prolonged.
Description
Technical field
The present invention relates to a kind of automobile front chamber stiffening device.
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 twisting or regional area large deformation about vehicle body when road traveling, expendable plastic deformation even fracture can appear in long duration of action.
At present automobile often adopts a large amount of loaded down with trivial details designs to promote torsional stiffness in the front deck design, performance difficulty on the technique not only, and can gain in weight.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of automobile front chamber stiffening device 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.
Technical scheme of the present invention is that this kind automobile front chamber stiffening device comprises connecting panel and pipe link, and described connecting panel has two, is installed in respectively the two ends of pipe link, and the connecting panel left-right symmetric is installed.
Described connecting panel and pipe link are split-type structural, 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 the 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.
This kind automobile front chamber stiffening device with said structure has the following advantages:
1. this kind automobile front chamber stiffening device is connected on the damper base of the left and right sides by this device, zone about front deck effectively can be coupled together, and simple in structure, it is little to take up room.
2. this kind automobile front chamber stiffening device is selected suitable material and thickness through finite element analysis and verification experimental verification, 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 invention is described further:
Fig. 1 is the structural representation of invention.
Fig. 2 is the structural representation of pipe link among the present invention.
Fig. 3 is the structural representation of connecting panel among the present invention.
In Fig. 1-3,1: connecting panel; 2: pipe link.
The specific embodiment
By the combination of structure shown in Fig. 1-3 as can be known, this kind automobile front chamber stiffening device comprises connecting panel 1 and pipe link 2, and connecting panel 1 has two, is installed in respectively the two ends of pipe link 2, and connecting panel 1 left-right symmetric is installed; Connecting panel 1 is split-type structural 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 the bumper by bolt.
This kind automobile front chamber stiffening device is connected on the damper base of the left and right sides by this device, zone about front deck effectively can be coupled together, and simple in structure, it is little to take up room; 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.
