Abstract
The utility model relates to a wheel hub unit, and particularly relates to a wheel hub unit with a magnetic sealing mechanism, which is used in a wheel hub of an automobile. The wheel hub unit comprises an inner ring with an assembly cavity, and an outer ring is sleeved outside the inner ring; steel balls are arranged between two ends of the upper part of the inner ring and the outer ring, and the steel balls are positioned by a retaining frame; the tail part of the inner ring and the tail part of the outer ring are sealed through a magnetic sealing ring, and the head part of the outer ring extends towards the outside of the inner ring. The wheel hub unit with a magnetic sealing mechanism has a compact structure, the assembly precision is improved, and the service life is improved.
Description
Technical field
The utility model is a kind of hub, and particularly a kind of hub of carrying magnetic sealing mechanism is used for the wheel hub of automobile.
Background technique
Hub structure relative complex of the prior art, and assembly precision is lower, and using effect is unoutstanding simultaneously.
Chinese patent 200420119173.7 discloses a kind of hub with bearing, comprises flange plate, it is characterized in that described flange plate is provided with bearing support outward, is provided with two single-row conical bearings between flange plate and the bearing support; Flange plate is provided with back-up ring near the axle journal outer radius of small end face, and the back-up ring end face compresses the large end face of bearing one inner ring; Bearing support internal diameter both sides are provided with seal ring, and its outside internal diameter contacts with the flangeseal step, and inboard internal diameter contacts with the external diameter of back-up ring.This structure relative complex, and using effect is relatively poor, and working life is shorter simultaneously.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, compact structure, and installation precision is high simultaneously, the hub of the carrying magnetic sealing mechanism that increases the service life.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of hub of carrying magnetic sealing mechanism, comprise the inner ring with assembly cavity, described inner ring overcoat has the outer ring, be respectively equipped with steel ball between the two ends on described inner ring top and outer ring, described steel ball is located mutually by retainer, the afterbody of described inner ring seals by magnetic gasket mutually with the afterbody of outer ring, and the head of described outer ring is to the inner ring extension.
This structure is relatively simple, and applicability is strong.
As preferably, the interposition of described assembly cavity is provided with the assembling ring recess, and described magnetic gasket envelopes the afterbody of outer ring.
As preferably, described outer ring is provided with equally distributed pilot hole.
Therefore, the hub of the carrying magnetic sealing mechanism that the utility model provides, compact structure improves assembly precision, promotes working life.
