A kind of automobile steering system seal, including inner seal liner and outside seal, the inner seal liner include interior sealing
Rubber parts and interior sealing plastic skeleton, the lower shape of interior sealing rubber parts matches with the shape of interior sealing plastic skeleton, interior
Caulking gum part is buckled on interior sealing plastic skeleton；The small foaming piece of external seal is fixed on the inner side bottom of external seal plastic skeleton
End, the big foaming piece of external seal are fixed on the upside of external seal plastic skeleton；The external seal plastic skeleton, the big foaming piece of external seal
The outside seal of foaming piece composition small with external seal snaps connection with inner seal liner；The material of the external seal plastic skeleton is to change
Property polypropylene.
As further program of the utility model：The modified polypropene is to add percetage by weight in polypropylene to be
40% talcum powder.
As the utility model further scheme：The material of the interior sealing plastic skeleton is to be modified polypropylene, institute
The material for stating interior sealing rubber parts is ethylene propylene diene rubber.
As the utility model further scheme：The material of the big foaming piece of the external seal and the small foaming piece of external seal
It is ethylene propylene diene rubber.
As the utility model further scheme：The small foaming piece of external seal is moulded by glue bonding in external seal
Expect the inner lower edge of skeleton.
As the utility model further scheme：The big foaming piece of external seal is moulded by glue bonding in external seal
Expect the upside of skeleton.
Compared with prior art, the beneficial effects of the utility model are：
The utility model solves the problems, such as that turning machine housing farther out, is ensureing that steering seal is normal apart from vehicle body sheet metal
Work, and in the case of turning machine and the correct assembling of vehicle body sheet metal, realize the leakproof for turning to seal during vehicle use
Water, infiltration, and reduce front deck to the noise transmission of driver's cabin.
Brief description of the drawings
Fig. 1 is the exploded view of automobile steering system seal.
Fig. 2 is the internal structure schematic diagram of automobile steering system seal.
In figure：1- interior sealing rubber parts, 2- interior sealing plastic skeletons, the big foaming piece of 3- external seals, the small foaming of 4- external seals
Part, 5- external seal plastic skeletons.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to Fig. 1~2, in the utility model embodiment, a kind of automobile steering system seal, including inner seal liner and
Outside seal, the inner seal liner include interior sealing rubber parts 1 and interior sealing plastic skeleton 2, the bottom shape of interior sealing rubber parts 1
Shape is matched with the shape of interior sealing plastic skeleton 2, and interior sealing rubber parts 1 is buckled on interior sealing plastic skeleton 2；The interior sealing
The material of plastic skeleton 2 is modified polypropylene (PP+TD40), and modified polypropene (PP+TD40) adds weight hundred in polypropylene
Fraction is 40% talcum powder, and the material of the interior sealing rubber parts 1 is ethylene propylene diene rubber (EPDM)；
The small foaming piece 4 of external seal is by glue bonding in the inner lower edge of outer sealed plastic skeleton 5, the big hair of external seal
Part 3 is steeped by glue bonding in the upside of outer sealed plastic skeleton 5；The small main function of foaming piece 4 of external seal is to turning to casing
The contact of body and external seal plastic skeleton 5 plays cushioning effect, avoids vehicle from causing therebetween due to vibrating during travelling
Percussion；The big foaming piece 3 of external seal mainly seals to outside seal, with vehicle body sheet metal in interference fit, the part
The impact test of high temperature hydraulic pressure is subjected to, to ensure preventing water leakage performance；The big foaming piece 3 of the external seal plastic skeleton 5, external seal
The outside seal that foaming piece 4 small with external seal forms snaps connection with inner seal liner；The big foaming piece 3 of the external seal and outer close
The material for sealing small foaming piece 4 is ethylene propylene diene rubber (EPDM), and the material of the external seal plastic skeleton 5 is modified polypropylene
