Description
Technical field
The utility model patent relates to a kind of hub, relates in particular to a kind of hub assembly of carrying magnetic coder, and hub is used for automobile.
Background technology
Present automobile hub unit of the prior art, the structure relative complex, assembly precision is low, and trouble is installed, and result of use is not good, all is the split design, influences overall performance.
Chinese patent CN200620108249.5, a kind of automobile hub unit assembly is disclosed, comprise mandrel, outer ring, inner ring, first rolling body and second rolling body, the outside of mandrel is furnished with raceway groove, the inboard of outer ring is furnished with the biserial raceway groove, clamping has first rolling body between outer ring and the inner ring, clamping has second rolling body between outer ring and the mandrel, inner ring is fixed on the mandrel that passes from its inside, the external diameter interference fit of the internal diameter of inner ring and mandrel forms and is fixedly connected, the spinning riveted construction is adopted in the end of mandrel, and the spinning riveted construction is close to the large end face of inner ring.This structure relative complex, and assembly precision is relatively low, and result of use is unoutstanding.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, provides a kind of simple in structure, use convenient, the hub assembly of the carrying magnetic coder that performance is outstanding.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A kind of hub assembly of carrying magnetic coder, comprise the flange that has axis hole, the head of described flange is provided with the inner ring that is halved together with it, described inner ring and flange are with the outer ring outward, form the retainer cavity between described inner ring and flange and outer ring, the head of described retainer cavity is provided with holder, the afterbody of described retainer cavity is provided with down retainer, be respectively equipped with steel ball in described holder and the following retainer, be provided with the magnetic skeleton between the head of described outer ring and the head of inner ring.
This structure relative compact, while assembly precision height, the simultaneous wheels hub unit has stronger leak tightness and water-proofness, prolong the service life of retainer, improve whole service property (quality) and service life, possess the magnetic skeleton, in-use performance further promotes, the deceleration and stopping performance of product.
As preferably, seal mutually by last sealing member between described inner ring and outer ring, describedly go up sealing member and the magnetic skeleton fits, seal mutually by lower seal between described flange and outer ring.
As preferably, described outer ring is provided with three assembling knuckles, is provided with assembly opening in the described assembling knuckle, and described flange is provided with the well-distributed fixed orifice.
Therefore, the hub assembly of carrying magnetic coder of the present utility model, compact conformation, the setting accuracy height, in-use performance is outstanding, promotes deceleration and stopping performance.
