Description
Technical field
This utility model belongs to automotive chassis components, is specifically related to a kind of pinion and-rack manual steering gear assembly steering spindle
Dust cover structure.
Background technology
Vehicle is in steering procedure, and steering moment is delivered to steering column assembly by steering wheel by driver, by steering column
Assembly passes to steering assembly, is then reached the purpose turned to by steering assembly band motor car wheel.Steering moment transmittance process
In, body front panel certainly exists a via, it is ensured that passing through of steering mechanical parts.Muddy water, sandstone, noise can be by being somebody's turn to do
Via enters into driving cabin from the external world, and steering spindle dust cover is used for blocking this via exactly, intercepts muddy water, sandstone, the entering of noise
Enter.
In the market, major part steering spindle dust cover is by the base of PP material and common EPDM rubber (Ethylene-
Propylene-Diene tripolymer Chinese: ethylene-propylene-dicyclopentadiene terpolymers, i.e. ethylene-propylene-diene monomer
Glue) composition, see Fig. 1, its PP base 3 is fitted on steering gear housing 7 with the form of interference fit, non-foamed EPDM compression layer
1 is assemblied on PP base 3 by rubber snap close 2.During assembling, steering spindle dust cover passes pinion shaft 9, one end and steering gear housing
Body 7 interference fit, the other end and vehicle body via 8 interference fit.Pinion shaft 9, in this structure, is passed by steering spindle dust cover
Vehicle body via 8 fully seals with the external world, prevents muddy water, sandstone to enter driving cabin and causes damage to vehicle, can also hinder simultaneously
The noise that only electromotor and periphery produce enters driving cabin and interferes driver and occupant thereof.Steering spindle dust cover is in assembling
It is completely in resting state after car load.But, the steering spindle dust cover of above structure is when coordinating with vehicle body via 8, because of material
Material structure limits, and magnitude of interference maximum is less than 8mm, can intercept the muddy water in the external world, sandstone, but to the barriering effect of noise relatively
Difference, the noise that electromotor produces in operation process can incoming driving cabin, driver and member thereof are interfered, affect driving
And riding comfort.
Utility model content
This utility model is for the deficiency of existing steering spindle dust cover, it is provided that a kind of steering spindle dust cover, this structure can
The contact area limited with vehicle body via bears the bigger magnitude of interference, effectively intercepts noise by the incoming driving of vehicle body via
Cabin, improves driver and the driving of occupant and riding comfort.
The technical solution of the utility model is:
A kind of steering spindle dust cover structure, is pressed by the EPDM of the base of PP material, the EPDM articulamentum of non-foamed and foaming
Contracting layer forms;Base is the hollow circular cylinder that diameter big mid diameter in two ends is little, and articulamentum and compression layer are hollow cylinder, even
Connecing layer lower end and be assemblied in the upper end of base with the form withheld, compression layer is connected with the epimere stickup of articulamentum by seccotine;
Articulamentum is the wave structure with certain decrement.
Further, compression layer surface is the graininess sealing surface of distribution hemi-spherical granule.
This utility model uses above technical scheme, is fitted on steering gear housing with the form of interference fit, non-foamed
The articulamentum of EPDM and the EPDM compression layer of foaming jointly act on, with vehicle body via interference fit, reach the pressure of at least 10mm
Contracting amount, plays obstruct muddy water, sandstone, the effect of noise.The bigger magnitude of interference can evade that vehicle body via flatness is overproof to be caused
The risk that noise is revealed, the combination of the articulamentum of the EPDM of non-foamed and the EPDM compression layer of foaming provides the compression of at least 10mm
Amount, is not only able to provide better seal, and non-foamed EPDM articulamentum wave structure can be at the Life Cycle of vehicle
It is always maintained at preferable resilience in phase, there is the advantages such as preferable durability.
It addition, even if vehicle body crosses hole surface there is the defect such as out-of-flatness or welding slag, granular sealing surface can also have
Imitate contacts sealing with vehicle body via, reduces the risk that noise is revealed further.Compression layer uses bonding form with articulamentum
Connect, replace rubber snap close to simplify structure, not only reduce cost but also can effectively prevent the ageing failure of rubber snap close.
Therefore, this utility model volume is little, and simple in construction is practical, has outstanding sound insulation capabilities.

Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Seeing Fig. 1, existing steering spindle dust cover is made up of PP base 3, non-foamed EPDM compression layer 1 and rubber snap close 2.
Non-foamed EPDM compression layer 1 is assemblied on PP base 3 by rubber snap close 2.
Seeing Fig. 2, steering spindle dust cover 10 of the present utility model is by PP base 3, non-foamed EPDM articulamentum 4 and foaming
EPDM compression layer 6 is constituted, and they are all hollow cylinder structure.
First by the characteristic of the elastic deformation of the lower end utilization of non-foamed EPDM articulamentum 4 itself with the form assembling withheld
On PP base 3, then foaming EPDM compression layer 6 is pasted onto with seccotine 5 upper surface of non-foamed EPDM articulamentum 4.
During assembling, steering spindle dust cover 10 is press fit into steering gear housing 7 through pinion shaft 9 with the form of interference fit
On, steering spindle dust cover 10 is mounted on steering assembly, becomes a part for steering assembly.
As shown in Figure 3, Figure 4, during car load assembles, steering assembly is mounted on vehicle body, and pinion shaft 9 passes
Vehicle body via 8 enters driving cabin.In the process, the graininess sealing surface 61 on the foaming EPDM compression layer of steering spindle dust cover
First contact with vehicle body via 8, the most gradually compressed, make non-foamed EPDM articulamentum 4 and foaming EPDM compression layer 6 become
Shape, wherein the wave structure 41 of non-foamed EPDM articulamentum bears most deflection, and foaming EPDM compression layer 6 also occurs
Elastic deformation.On graininess sealing surface 61, each hemispheric granule all deforms and fully connects with vehicle body via 8 surface
Touch, and then make granular sealing surface 61 accomplish seamless applying with vehicle body via 8.
The foaming granular sealing surface of EPDM compression layer 61 of this steering spindle dust cover fits with vehicle body via 8, non-
Bubble EPDM articulamentum 4, foaming EPDM compression layer 6 occur elastic deformation can meet the decrement requirement of at least 10mm.This structure
Can intercept sandstone completely, muddy water enters driving cabin by vehicle body via, and noise also can only penetrate steering spindle dust cover originally
Body or body front panel could enter driving cabin, and the noise entering driving cabin under this situation also can be greatly reduced.And
After high mileage uses, the wave structure of this non-foamed EPDM articulamentum still can continue to keep good resilience, compression
Amount decay is few, it is ensured that vehicle, in using life cycle, can effectively intercept the entrance of muddy water, sandstone, noise.
