This kind of automobile front chamber stiffening device with above-mentioned special construction is connected on the damper base of left and right by this device, region, front deck left and right effectively can be coupled together, simple in structure, takes up room little; Through finite element analysis and verification experimental verification, select suitable material and thickness, this device can effectively improve the torsional rigidity of vehicle body, and then promotes its service life.<!--1-->
Description
Technical field
The present invention relates to a kind of automobile front chamber stiffening device.
Background technology
The torsional rigidity of vehicle body has directly the performance of car load each side as the important mechanical property of vehicle bodyThe impact connecing, good body torsional rigdity not only can improve the NVH performance of car load, and to automobileLife-span also have greatly improved. The automobile that torsional rigidity is poor, outside being subject in the time of road travelingPower effect tends to occur the twisting of vehicle body left and right or regional area large deformation, long duration of action meetingOccur that expendable plastic deformation even ruptures.
Automobile, in front deck design, often adopts a large amount of loaded down with trivial details designs to promote torsional rigidity at present,Not only performance difficulty in technique, and can gain in weight.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of vapour for problems of the prior artCar front deck stiffening device, its objective is and obviously improve reducing to add under the prerequisite of tare as far as possibleThe torsional rigidity of vehicle body entirety.
Technical scheme of the present invention is that this kind of automobile front chamber stiffening device comprises connecting plate and connecting rod, andDescribed connecting plate has two, be arranged on respectively the two ends of connecting rod, and connecting plate is symmetricalInstall.
Described connecting plate and connecting rod are split-type structural, and connecting plate adopts punch forming, connectionThe surface of plate and the laminating of the damper of automobile front chamber, and be directly installed on damper by bolt。
Described connecting rod adopts rolling technology moulding.
The cross section of described connecting rod is square or circular.
Welding together by carbon-dioxide arc welding of the end of described connecting rod and connecting plate.
This kind of automobile front chamber stiffening device with said structure has the following advantages:
1. this kind of automobile front chamber stiffening device is connected on the damper base of left and right by this device, can be byRegion, front deck left and right effectively couples together, simple in structure, takes up room little.
2. this kind of automobile front chamber stiffening device, through finite element analysis and verification experimental verification, selected suitable materialMaterial and thickness, this device can effectively improve the torsional rigidity of vehicle body, and then promotes its useLife-span.
Brief description of the 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 connecting rod in the present invention.
Fig. 3 is the structural representation of connecting plate in the present invention.
In Fig. 1-3,1: connecting plate; 2: connecting rod.
Detailed description of the invention
From structure shown in Fig. 1-3 in conjunction with, this kind of automobile front chamber stiffening device comprises connecting plate 1 and connectsExtension bar 2, connecting plate 1 has two, is arranged on respectively the two ends of connecting rod 2, and connecting plate 1 left and rightSymmetrical installation; Connecting plate 1 is split-type structural with connecting rod 2, and connecting plate 1 adopts punch forming, the surface of connecting plate 1 and the laminating of the damper of automobile front chamber, and be directly installed on and subtract by boltOn shake device.
Connecting rod 2 adopts rolling technology moulding, and the cross section of connecting rod 2 is square or circular. ConnectWelding together by carbon-dioxide arc welding of the end of extension bar 2 and connecting plate 1.
This kind of automobile front chamber stiffening device is connected on the damper base of left and right by this device, can be by frontRegion, left and right, cabin effectively couples together, simple in structure, takes up room little; Through finite element analysisAnd verification experimental verification, select suitable material and thickness, this device can effectively improve vehicle bodyTorsional rigidity, and then promote its service life.
