Abstract
The utility model relates to a vibration isolator of car body cavity in the front end of the car trailing wheel casing, comprising a heat-resistant hard frame and a foaming body in which can generate foam and expand after being heated up; wherein, the frame comprises a panel and a fixture connected with one side of the panel and used for fixing the corresponding parts in the car body; the panel has a similar plane shape with the section of the car body cavity in the front end of the car trailing wheel casing and has clearances at the periphery with the corresponding sections for foaming expansion of the foaming body; the foaming body is covered on the panel and has a thickness which can fill in the clearance of the vibration isolator and the car body after foaming expansion. The utility model has the advantages of enabling to bond with the car body plate after being preassembled in the car body cavity in the front end of the car trailing wheel casing, therefore separating the cavity channel and further improving the performances of car cockpits of vibration isolation, sound insulation, vibration damping and noise reduction.
Description
Technical field
The utility model relates to a kind of auto parts and components, relates in particular to a kind of car rear wheel cover front end in-to-in car body cavity vibration isolating pad that is arranged on.
Background technology
Along with developing of automobile industry, people are more and more higher to the requirement of " safety, traveling comfort, the feature of environmental protection " of car, and the standard-required to " sound insulation, vibration isolation, anticorrosion, noise control " in the car passenger cabin also constantly promotes.The AE personnel have located to do the technology upgrading of sound insulation vibration isolation to ride-control, sound-heat insulated cushion, car internal sound insulation, vibration isolation carpet, vehicle body sticking glass, car roof etc. in car at present, make vibration and noise in the car passenger cabin obtain the actv. improvement.But the cavity passage in the body structure also can produce the noise with transmitting vibrations, and this technical matters is not well solved all the time.
The manufacturing process of vehicle body is, earlier with sheet metal by the die stamping moulding after, form by Automobile Plate metal seam such as inner panel, brace panel and outside plates.Therefore generally in the middle of inner panel and brace panel and outside plate, be bound to form necessary gap and space, be included in zones such as body platform beam, A, B, C, D column, rear wheel cover, ceiling, upper/lower terminal dash shield, ceiling, fender upper end, back and four door-plates and all can form cavity.Particularly Reinforcement A, B, C, D column and two bottom sides longeron have all formed the column structure spare of hollow.The hollow structure of these column pieces and longeron has guaranteed the intensity and the rigidity of body structure effectively, so the cavity state in the body structure is must have.But the cavity of this body structure has also formed the specific channel that transmits ambient noise and vibration.The metal sheet of the ceiling of vehicle body, the isometric form of longeron can form sound because of distortion, the vibration of structure when crossing the road ditch; In the high vehicle speeds motion, can form the sympathetic response sound to vehicle body because of extraneous blast, windage again; The pavement of road sandstone also can on the go to the vehicle body sound that impacts; The resonance frequency that produces in the motion can form the vibration and the sound to vehicle-body outer panel.These noises and vibration all can be transmitted in the cavity between the inside and outside plate of vehicle body fast, thereby noise and transfer of vibration are arrived in the passenger cabin of car, influence driver and conductor's traveling comfort.
Summary of the invention
The purpose of this utility model is exactly in order to solve the problem that above-mentioned prior art exists, thus provide a kind of can seal that bodywork cavity can improve vibration in the car passenger cabin and noise effectively be arranged on car rear wheel cover front end in-to-in car body cavity vibration isolating pad.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of car rear wheel cover front end in-to-in car body cavity vibration isolating pad that is arranged on, comprise can foaming and intumescing after heat-resisting hard skeleton and the heating foaming body, described skeleton comprise a panel and be connected panel one side be used for vehicle body in the connecting element that is connected and fixed of corresponding component, described panel has the similar aspect in cross section to car rear wheel cover front end in-to-in bodywork cavity, and leaves the gap that supplies the foaming body foaming and intumescing with respect to the periphery of respective cross-section; Described foaming body covers on this panel and has at the thickness that can fill up the gap between vibration isolating pad and the vehicle body behind the foaming and intumescing.
Also be connected with two legs on the described panel, one of them is connected an end of panel perpendicular to panel, and another is parallel to the other end that panel is connected panel.
Described panel is provided with a plurality of posts that are used to be connected and fixed foaming body.
Described foaming body is closing on the raised line that the connecting element place is provided with thickening.
In in conjunction with the Automobile manufacturing technological process, rationally reach desirable task program, car body cavity vibration isolating pad of the present utility model is arranged in the car rear wheel cover front end in-to-in bodywork cavity, by the time body in white through pickling, neutralization, purifying, phosphatization, enters in the stoving of the paint stove behind first road paint again and toasts.In stove behind 160～190 ℃ of high temperature and certain hour, foaming body is finished the foaming bonding, the car body panel of vibration isolating pad and rear wheel cover bottom closely is bonded to one, can intercept the cavity passage at this place effectively, simultaneously also to launch the Stone Shock acoustic damping at rear wheel cover place because of the ground sandstone, reach totally-enclosed, thereby vibration source and noise that original rear wheel cover place is imported into through bodywork cavity intercept, and reach the purpose of further improving the interior vibration isolation of car passenger cabin, sound insulation, vibration damping, noise reduction.Simultaneously, after car body cavity vibration isolating pad foamed in bodywork cavity and bonds, the intensity of also further having reinforced vehicle body had all played optimization function to body structure and vehicle body crash-protective characteristics, makes the traveling comfort of car and safety obtain important lifting.
Description of drawings
Fig. 1 is the perspective view that the utility model is arranged on car rear wheel cover front end in-to-in car body cavity vibration isolating pad;
Fig. 2 is that vibration isolating pad shown in Figure 1 is seen end elevation in the past from small end;
