The problem of cover body cannot be installed；It can guarantee good sealing effect simultaneously；It is quick and easy for installation, it can be improved installation effect
Rate also can reduce production cost and cost of labor.
A kind of vehicle steering shaft dust protector described in the utility model, including dust boot body, it is characterized in that: described dust-proof
Cover body includes pedestal, the dust-proof cushion with pedestal outer surface of upper cooperation；The lower part of the pedestal passes through diverter pinion gear
Axis and diverter cabinet cooperate；It is close to front wall board of automobile the upper surface of the dust-proof cushion.
Further, the top of the pedestal is that dust-proof cushion limiting section, lower part are positioned oneself portion；The dust-proof cushion with it is dust-proof
Pad the outer surface interference fit of limiting section, the internal surface gaps cooperation of the diverter pinion shaft and dust-proof cushion limiting section；Institute
It states self poisoning portion and the diverter cabinet is interference fitted.
Further, the dust-proof cushion limiting section is up-small and down-big cyclic structure, and the dust-proof cushion is cylindrical, along perpendicular
Histogram is to equipped with through-hole；The inner surface of the dust-proof cushion is close to the outer surface of upper of the dust-proof cushion limiting section, lower surface with
The step surface of the dust-proof cushion limiting section is close to.
Further, the self poisoning portion is cylindrical, and it is equipped with up-small and down-big ladder hole along the vertical direction；Institute
The lower part circular hole interior surface for stating self poisoning portion is close to the outer surface of upper of the diverter cabinet, step surface and the steering
It is close to the upper surface of device cabinet.
Further, the upper surface of the dust-proof cushion is equipped with multi-turn convex ribs.
Further, the pedestal is PP material, and the dust-proof cushion is blown rubber material.
The beneficial technical effect of the utility model:
Since dust boot body only includes pedestal and dust-proof cushion, so that the structure of dust boot body is simplified simply,
Volume is reduced, arrangement or installation space needed for reducing solve certain vehicles due between diverter and front wall board of automobile
Space is smaller, and the problem of cause dust boot body that cannot install；It ensure that good sealing effect simultaneously；It is easy for installation fast
Victory improves installation effectiveness, also reduces production cost and cost of labor.

Specific embodiment
It elaborates below in conjunction with drawings and examples to the utility model.
It is to Fig. 8, a kind of vehicle steering shaft dust protector, including dust boot body 1, substantive distinguishing features referring to fig. 4: described
Dust boot body 1 includes pedestal 51, the dust-proof cushion 52 with 51 outer surface of upper of pedestal cooperation；The lower part of the pedestal 51 passes through
Diverter pinion shaft 7 and diverter cabinet 6 cooperate；It is close to front wall board of automobile the upper surface of the dust-proof cushion 52.Dust cover
The structure of ontology 1 is simple, and dust-proof cushion 52 only needs pedestal 51 just can play good support effect, can reduce dust boot body
Volume, arrangement or installation space can be reduced, be suitable for the lesser vehicle in space between certain diverters and front wall board of automobile
Type, while can guarantee good sealing effect.
The top of the pedestal 51 is that dust-proof cushion limiting section 511, lower part are positioned oneself portion 512；The dust-proof cushion 52 with
The outer surface of dust-proof cushion limiting section 511 is interference fitted, the inner surface of the diverter pinion shaft 7 and dust-proof cushion limiting section 511
Clearance fit；The self poisoning portion 512 is interference fitted with the diverter cabinet 6.
The dust-proof cushion limiting section 511 is up-small and down-big cyclic structure, and the dust-proof cushion 52 is cylindrical, along vertical
Direction is equipped with through-hole 521；The inner surface of the dust-proof cushion 52 is close to the outer surface of upper of the dust-proof cushion limiting section 511, under
It is close to the step surface of the dust-proof cushion limiting section 511 on surface.Dust-proof cushion limiting section 511 can carry out dust-proof cushion 52 effectively
Limit, then by extruding of the front wall board of automobile to dust-proof cushion 52, so that dust-proof cushion 52 deforms, to play sealing function.
The self poisoning portion 512 is cylindrical, and it is equipped with up-small and down-big ladder hole 513 along the vertical direction；Institute
The lower part circular hole interior surface for stating self poisoning portion 512 is close to the outer surface of upper of the diverter cabinet 6, step surface with it is described
It is close to the upper surface of diverter cabinet 6.Dust boot body 1 can be effectively fixed in diverter cabinet 6 by self poisoning portion 512
On, the shaking of dust boot body 1 can be reduced.
The upper surface of the dust-proof cushion 52 is equipped with multi-turn convex ribs 522.Convex ribs 522 enable to dust-proof cushion 52 and automobile antetheca
Sealing effect between plate is more preferable.Preferably reduce since front wall board of automobile mating surface and the uneven caused sealing of dust-proof cushion 52 are imitated
The risk that fruit reduces.
The pedestal 51 is PP (polypropylene) material, and the dust-proof cushion 52 is blown rubber material.
Dust boot body 1 is simplified relative to existing vehicle steering shaft dust protector structure, while overall dimension obtains
To reduce；Be able to solve certain vehicles due between diverter and front wall board of automobile space it is smaller, and lead to dust boot body not
The problem of capable of installing；It is quick and easy for installation simultaneously, it can be improved installation effectiveness；Also production cost and cost of labor be can reduce.
