Abstract
The utility model discloses a kind of ABS gear rings and automotive hub dustproof construction with dust-proof member, including gear ring ontology and dust-proof member, the gear ring ontology includes the outer flank of tooth and inner ring surface, the dust-proof member is in a ring, it is integrally formed in gear ring ontology one end, its dust-proof member inner ring is consistent with the diameter of the inner ring surface of gear ring ontology, and outer ring protrudes from the outer flank of tooth of gear ring ontology.It disclosure satisfy that the performance of ABS gear rings and functional requirement, blocks dust enter in drive shaft in hub bearing, while dust can be effectively prevent to be accumulated at ABS inter-lobe clearances.
Description
Technical field
The utility model is related to automobile components, and in particular to carry the ABS gear rings and the dust-proof knot of automotive hub of dust-proof member
Structure.
Background technology
An important spare part of the drive shaft as car transmissions, even more current transfer motion power indispensable zero
Part, it is necessary to have higher reliability, NVH performances and preferable assembling and circulation property.For the cage assembly of fixing end, in addition to
Ensure outside the lubricity of part itself, flexibility and durability, it is necessary in the cleaning for ensureing brake bearing and by vehicle wheel
Speed accurately inputs to wheel speed sensors, in order to avoid brake end enters dust, influences service life and the use of driving shaft bearing
Effect influences ABS system and normally uses.
Referring to Fig. 3 and Fig. 4, shown in existing drive shaft dust-proof member, including dustproof cover 7, interference fit be fitted in
On the first step end face 31 of drive shaft 3, prevent dust or external foreign matter from entering in brake bearing, without the ABS of dust-proof surface
The interference fit of gear ring 6 is fitted on the second step end face 32 of drive shaft 3, ensures that wheel speed sensors can correctly read wheel speed.Its
Middle dustproof cover 7 and without dust-proof surface ABS gear rings 6 be mutually independent component, increase assembly process and assembly difficulty.
CN104500752A discloses a kind of automobile hub bearing dust-proof member, referring to Fig. 5, shown in band dust-proof surface ABS
A dust-proof surface 9 is specially designed on gear ring 8, the outer diameter of dust-proof surface 9 is consistent with 8 outer diameter of ABS gear rings with dust-proof surface, though this structure
Energy blocks dust immerses, but is easy that dust is made to accumulate at ABS inter-lobe clearances, influences vehicle wheel speed sensor and reads ABS gear rings
Reading.Therefore, it is necessary to develop a kind of novel dust-proof member with ABS gear rings.
Invention content
The purpose of this utility model is to provide ABS gear rings and automotive hub dustproof construction with dust-proof member, can
Meet performance and the functional requirement of ABS gear rings, blocks dust enters in drive shaft in hub bearing, while can effectively prevent ash
Dirt is accumulated in ABS inter-lobe clearances.
ABS gear rings described in the utility model with dust-proof member, including gear ring ontology and dust-proof member, the gear ring
Ontology includes the outer flank of tooth and inner ring surface, and the dust-proof member in a ring, is integrally formed in gear ring ontology one end, dust-proof member
Circle is consistent with the diameter of the inner ring surface of gear ring ontology, and outer ring protrudes from the outer flank of tooth of gear ring ontology.
Further, the dust-proof member and the outer flank of tooth slot bottom contact site of gear ring ontology pass through arc transition.
Further, the gear ring ontology and dust-proof member surface are equipped with spelter coating.
A kind of automotive hub dustproof construction, including drive shaft, knuckle and ABS gear rings, the gear ring ontology of the ABS gear rings
It is pressed in drive shaft, there are certain interval, the cooperations of the outer ring and knuckle of the dust-proof member of the ABS gear rings with knuckle
Gap is not more than 0.5mm.
The utility model has the advantages that compared with prior art：
1, since ABS gear rings and dust-proof member fitting are integrally formed, performance and the functional requirement of ABS gear rings had both been met,
Again can blocks dust enter in the hub bearing in drive shaft, play dustproof effect, reduce the inordinate wear of hub bearing, prolong
The service life of long hub bearing；It is described with dust-proof member since dust-proof member inner ring is consistent with gear ring ontology internal diameter
ABS gear rings reduce assembly process, reduce assembly difficulty by being interference fitted press fitting in drive shaft.
2, gear ring ontology is protruded from due to dust-proof member outer ring and is not more than 0.5mm with the fit clearance of knuckle, avoided
Dust is accumulated in ABS inter-lobe clearances.
3, since dust-proof member and gear ring body surface are equipped with spelter coating, ABS gear rings are avoided, corrosion occurs.

Specific implementation mode
It elaborates below in conjunction with the accompanying drawings to the utility model.
Referring to Fig. 1 and Fig. 2, the ABS gear rings of dust-proof member, including gear ring ontology 1 and dust-proof member 2, institute are carried shown in
It includes the outer flank of tooth and inner ring surface to state gear ring ontology 1, and the dust-proof member 2 in a ring, is integrally formed in 1 one end of gear ring ontology, prevents
2 inner ring of dirt component is consistent with the diameter of the inner ring surface of gear ring ontology 1, and outer ring protrudes from the outer flank of tooth of gear ring ontology 1.Due to ABS
