Description
Technical field
The utility model belongs to dust cover technical field, more particularly to a kind of dust cover of motor turning.
Background technique
Car steering tube column needs to install dust cover, and main function is to prevent the thing of dust or sandstone etc from passing through
The bottom plate hole of cab bottom enters driver's cabin, impacts to the normal operating of driver.The applying date is 2016.08.12, Shen
Please number be 201620872258.5 Chinese patent, including the shield, telescopic and bearing set gradually from bottom to top, shield packet
Pedestal and cone barrel cover are included, shield is connected with the lower end of telescopic, and bearing is nested in the upper port of telescopic, and pedestal is solid
Due on bottom plate of driving cab, bearing is fixed on rotatable tubing string.The patent solves dust cover and directly connects with steering column
The problem of connecing.But now with expanding economy, the improvement of people's living standards, requirement of the people to automobile is also increasingly
It is high.It is big that motor space is not required nothing more than, is also required comfortably, interior noise is small or even noiseless etc..And interior noise source has very
Big a part comes from tire, the incoming car in the position that tire, which is made an uproar, to be sealed from chassis or anti-acoustic capability is bad.If steering column
Dust cover noise reduction effect it is bad, noise will enter driver's cabin from bottom plate hole through dust cover, influence environment inside car.The patent
No noise reduction setting, is unable to satisfy requirement of the people to automobile high-quality, requires further improvement perfect.
Therefore, above-mentioned technical problem how to be overcome to become those skilled in the art's technical problem urgently to be resolved.
Utility model content
The purpose of this utility model is just to provide a kind of dust cover of motor turning, can be fully solved the above-mentioned prior art
Shortcoming.
The purpose of this utility model is realized by following technical proposals：
A kind of dust cover of motor turning, it is characterised in that：Including the shield, telescopic and axis set gradually from bottom to top
It holds, shield includes pedestal and cone barrel cover, and shield is connected with the lower end of telescopic, and bearing is nested in the upper port of telescopic
Interior, pedestal is fixed on bottom plate of driving cab, and soundproof plate is provided in the shield, tubing string via hole, tubing string are provided on soundproof plate
Nested installation bearing, bearing are fixed on rotatable tubing string on via hole, and the soundproof plate is disposed with first from bottom to up

Second industrial rubber and plastic boards layer.
Further, the soundproof plate is at least arranged one layer.
Further, the spongy layer with a thickness of 3-5mm.
Further, the thickness of the first rubber slab layer and the second rubber slab layer is 5-1mm.
Further, the thickness of the described first industrial rubber and plastic boards layer and the second industrial rubber and plastic boards layer is 2-4mm.
Compared with prior art, the beneficial effects of the utility model are：Structure is simple, and design rationally, can not only be effective
It is dust-proof, moreover it is possible to which that effective sound insulation, heat-insulated, good airproof performance are easy to maintenance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment one；
Fig. 2 is the structural schematic diagram of soundproof plate；
Fig. 3 is the structural schematic diagram of the utility model embodiment two.
Appended drawing reference：The industrial rubber and plastic boards layer 11 of soundproof plate 1, tubing string via hole 2, first, first the 12, first industry of rubber slab layer
Felt layers 13, spongy layer 14, the second industrial felt layer 15, second the 16, second industrial rubber and plastic boards layer 17 of rubber slab layer, flexible corrugation
Pipe sleeve 3.
Specific embodiment
The utility model is further described with attached drawing combined with specific embodiments below.
Embodiment one
As shown in Figure 1 to Figure 2, a kind of dust cover of motor turning, including shield, the telescopic set gradually from bottom to top
And bearing, shield include pedestal and cone barrel cover, shield is connected with the lower end of telescopic, and bearing is nested in the upper of telescopic
In port, pedestal is fixed on bottom plate of driving cab, and soundproof plate 1 is provided in the shield, tubing string via hole is provided on soundproof plate 1
2, nested installation bearing, bearing are fixed on rotatable tubing string on tubing string via hole 2.The soundproof plate 1 is successively set from bottom to up
It is equipped with the first industrial rubber and plastic boards layer 11, the first rubber slab layer 12, the first industrial felt layer 13, spongy layer 14, the second industrial felt
The 15, second rubber slab layer of layer 16 and the second industrial rubber and plastic boards layer 17.
The soundproof plate 1 is at least arranged one layer, and soundproof plate 1 may be configured as the wave-like with certain retractility.
The spongy layer 14 with a thickness of 3-5mm.
The thickness of the first rubber slab layer 12 and the second rubber slab layer 16 is 5-1mm.
The thickness of described first industrial rubber and plastic boards layer 11 and the second industrial rubber and plastic boards layer 17 is 2-4mm.
Bearing on the bearing and soundproof plate 1 of telescopic upper port is to be interference fitted to install with rotatable tubing string.
In the description of the present invention, it should be noted that the indicating positions such as term " on ", "lower" or positional relationship
For orientation based on the figure or positional relationship, it is merely for convenience of this practical and simplified description of description, rather than is indicated
