Abstract
The invention discloses an automobile roof front beam with function of reducing vibration, comprising a front beam; and a liner plate is fixed in the middle of the upper surface of the front beam. The roof front beam effectively reduces the vibration efficiency of the automobile roof front beam and simultaneously enhances the bending rigidity of the roof front beam.
Description
Technical field
The present invention relates to auto parts and components, be specifically related to the front cross rail of automobile top-cap.
Background technology
The automobile top-cap front cross rail is a supporting vehicle right and left gusset, supports the key structure spare that front windshield is installed, and is one of necessary member of body framwork.Because vehicle body all is the pipe girder construction, the NVH vibration problem that suspension and dynamic assembly cause can be delivered to the top cover front cross rail and it is amplified through the pipe girder construction, and vibration mainly concentrates on the medium position of top cover front cross rail, makes the passenger feel uncomfortable.
Summary of the invention
The purpose of this invention is to provide a kind of automobile top-cap front cross rail, to reduce the oscillation frequency of automobile top-cap front cross rail with vibration-damping function.
Automobile top-cap front cross rail with vibration-damping function according to the invention comprises front cross rail, is fixed with liner plate in the upper surface middle part of front cross rail.
Said liner plate is rectangular, is provided with project-welding nut at its two ends, and liner plate is fixed on the front cross rail with bolt through two project-welding nuts.
Said liner plate is that thickness is the steel plate of 4～10mm, can reach the better damping effect like this.
The present invention is through setting up liner plate; Increase the thickness at automobile top-cap front cross rail middle part, thereby reduce the natural frequency of automobile top-cap front cross rail, so can effectively reduce the vibration of automobile top-cap front cross rail; Improve the NVH performance of car load, also increased the bending stiffness of top cover front cross rail simultaneously.
Description of drawings
Fig. 1 is that the said axle with automobile top-cap front cross rail of vibration-damping function of invention is surveyed scheme drawing;
Fig. 2 is the cutaway view of A among Fig. 1-A line.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further:
As depicted in figs. 1 and 2; This automobile top-cap front cross rail with vibration-damping function comprises front cross rail 1; Upper surface middle part at front cross rail 1 is fixed with liner plate 2, and this liner plate 2 is the steel plate of 4mm for thickness, and is rectangular; Be provided with project-welding nut 3 at its two ends, liner plate 2 is fixed on the front cross rail 1 through two project-welding nuts, 3 usefulness bolts 4.
The thickness of above-mentioned liner plate 2 also can be 7mm or 10mm.
Claims (3)
