Description
Technical field
The present invention relates to field of automobile, the seal between specially a kind of steering and front baffle.
Background technology
For changing or keeping a series of devices of running car or reverse direction to be referred to as automobile steering system.Motor turning
The function of system is exactly that the travel direction of automobile is controlled according to the wish of driver.Driving safety of the automobile steering system to automobile
It is most important, therefore the part of automobile steering system referred to as security personnel's part.Automobile steering system and brakes are all automobile peaces
The full two systems for having to pay attention to.Seal is provided between steering column for vehicles and front baffle.Current seal is located at
Turn at axis, structure is mainly made up of three parts, including plastic bearing, dust cover, bellows, and it is close to firmware spiral shell
Bolt or nut are fixed in front baffle, and the fit dimension of itself and jackshaft is that gap coordinates, and this structure existing defects is mainly：It is close
Sealing can not fundamentally block the bang path of sound.Seal is that gap coordinates with steering intermediate shaft, and gap coordinates purpose
It is not produce abnormal sound during jackshaft to meet to rotate, but the noise outside driving cabin is passed to also by this gap and driven simultaneously
Sail in cabin, driving cabin NVH perceived qualities are poor.
The content of the invention
It is an object of the invention to provide the seal between a kind of steering and front baffle, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the present invention provides following technical scheme：A kind of sealing between steering and front baffle
Part, including steering column and front baffle, the crossover port for installing steering column is offered in the front baffle, and the steering column passes through
Clutch shaft bearing is arranged on the crossover port, and the lower surface of the front baffle is fixedly installed silencing means, the silencing means
Including sound attenuation, the edge at the top of the sound attenuation is fixed with adpting flange, and screw is provided with the adpting flange
Hole, the adpting flange on the sound attenuation are fixedly mounted on the lower surface of the front baffle, the sound attenuation by screw
Bottom be provided with and pass through second bearing and the steering column with the corresponding mounting hole in the steering hole site, the mounting hole
It is flexibly connected, acoustical panel is provided with the sound attenuation.
Preferably, it is provided with cushion pad between the adpting flange on the sound attenuation and the front baffle.
Preferably, the top of the clutch shaft bearing is being provided with dust ring between the front baffle and steering column.
Preferably, it is evenly distributed with sound attenuation hole on the acoustical panel.
Preferably, the acoustical panel is in the sound attenuation internal layer fold-type structure.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, the present invention is fixedly installed silencing means by the lower surface in front baffle, is set in the sound attenuation of silencing means
There is acoustical panel, steering column is flexibly connected with front baffle and sound attenuation respectively by clutch shaft bearing and second bearing, in engine
Firstly the need of by silencing means, noise quilt in sound attenuation when caused noise is transferred to cockpit by front baffle in storehouse
Acoustical panel absorbs so that caused noise only has small part to be transferred to cockpit in engine bin, so as to block sound
The path of sound transmission, driving cabin NVH perceived qualities are good.
2nd, the present invention has the advantages that simple in construction, easy for installation, easy to use, using effect is good.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Fig. 1-2 is referred to, the present invention provides a kind of technical scheme：A kind of seal between steering and front baffle,
Including steering column 1 and front baffle 3, the crossover port 2 for installing steering column is offered in the front baffle 3, the steering column 1 is logical
Clutch shaft bearing 13 is crossed on the crossover port 2, the lower surface of the front baffle 3 is fixedly installed silencing means 11, described
Silencing means 11 includes sound attenuation 5, and the edge at the top of the sound attenuation 5 is fixed with adpting flange 8, the adpting flange
It is provided with screw hole on 8, the adpting flange on the sound attenuation 5 is fixedly mounted on the following table of the front baffle 3 by screw 7
Face, the bottom of the sound attenuation 5 are provided with the mounting hole 10 corresponding with the position of crossover port 2, and the mounting hole 10 is logical
Cross second bearing 6 to be flexibly connected with the steering column 1, acoustical panel 4 is provided with the sound attenuation 5.
