Abstract

The utility model relates to a hub unit, particularly to a hub unit with a dust cover, which is applied to automobiles, and includes a flange, wherein a wide inner ring and a narrow inner ring are sleeved on the flange; an outer ring is sleeved outside the wide inner ring and the narrow inner ring respectively; a cage passage is formed among the outer ring, the wide inner ring and the narrow inner ring; a pair of embedded cages is arranged in the cage passage; rollers are arranged in the cages; a gear ring is sleeved on the wide inner ring; the dust cover is arranged on the outer ring; a sensor is inserted to the outer ring; and the sensor corresponds to the gear ring. The hub unit with the dust cover has simple structure, high mounting precision, prolonged service life and remarkable use effect.

Description

The hub of band cover of dust

Technical field

The utility model patent relates to a kind of hub, relates in particular to a kind of hub with cover of dust, and hub is used for automobile.

Background technology

The automobile hub unit of present prior art, the structure relative complex, assembly precision is low, and trouble is installed, and result of use is not good.

Chinese patent CN200620108249.5 discloses a kind of automobile hub unit assembly, comprises 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, and clamping has first rolling body between outer ring and the inner ring, and 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, and 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 deficiency that exists in the prior art, provides a kind of simple in structure, and the hub of the outstanding band cover of dust of result of use.

The above-mentioned technical matters of the utility model mainly is able to solve through following technical proposals:

A kind of hub with cover of dust comprises flange, is with wide inner ring and narrow inner ring on the described flange; Described wide inner ring and narrow inner ring are with the outer ring outward; Form the retainer passage between described outer ring and wide inner ring and narrow inner ring, be provided with a pair of retainer that is halved together in the described retainer passage, be provided with roller in the described retainer; Be with gear ring on the described wide inner ring; Described outer ring is provided with cover of dust, is plugged with sensor on the described outer ring, and described sensor is corresponding with gear ring.

This structure relative compact, assembly precision is high simultaneously, and the simultaneous wheels hub unit has stronger leak tightness and water-proofness, prolongs the service life of retainer, improves single-piece service property (quality) and service life, and sensor can transmit signal accurately simultaneously.

As preferably, be respectively equipped with assembly opening on three angles of described outer ring, be evenly equipped with bolt on the described flange.

As preferably, described wide inner ring and narrow inner ring parallel splicing, and described gear ring is located in the retainer passage, described cover of dust and outer ring clamping mutually, and described sensor and outer ring diagonally distribute.

As preferably, seal mutually through poted assemblies between described outer ring and narrow inner ring, touch mutually through dust ring between described outer ring and wide inner ring.

Therefore, the hub of the band cover of dust of the utility model, simple in structure, setting accuracy is high, improves service life, and result of use is remarkable.
