Abstract
The utility model relates to a hub unit, in particular to a hub unit with a dual-seal unit. The hub unit is used for an automobile. The hub unit comprises a flange on which an inner circle is sleeved. An outer circle is sleeved outside the inner circle. A cage channel is formed between the outer and inner circles. A pair of cages is arranged in the cage channel, and the cages are distributed at an interval. Steel balls are arranged in the cages. An outer cover is sleeved on the outer circle and the head of the flange. The hub unit with the dual-seal component has a simple structure, and is high in mounting efficiency and remarkable in using effect; and the service life of the hub unit is prolonged.
Description
Technical field
The utility model patent relates to a kind of hub, relates in particular to a kind of hub with the double-sealing assembly, and hub is used for automobile.
Background technique
The automobile hub unit of present existing technology, the structure relative complex, assembly precision is low, and trouble is installed, and using effect is not good.
Chinese patent CN200620108249.5 discloses a kind of automobile hub unit assembly, comprises mandrel, outer ring, inner ring, first rolling element and second rolling element; 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 element between outer ring and the inner ring, and clamping has second rolling element 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 using effect is unoutstanding.
Summary of the invention
The utility model mainly is to solve the deficiency that exists in the existing technology, provides a kind of simple in structure, and the hub of the outstanding band double-sealing assembly of using effect.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of hub with the double-sealing assembly; Comprise flange plate, be with inner ring on the described flange plate, described inner ring is with the outer ring outward; Described outer ring and inner ring form the retainer passage; Be provided with the retainer that pair of spaced distributes in the described retainer passage, be provided with steel ball in the described retainer, the head of described outer ring and flange plate is with outer cover.
This structure relative compact, assembly precision is high simultaneously, and the simultaneous wheels hub unit has stronger sealing and water proofing property, prolongs the working life of retainer, improves whole service property (quality) and working life.
As preferably, described outer ring is provided with the pilot hole of two pairs of symmetrical distributions, and described flange plate is provided with bolt.
As preferably; Described inner ring and flange plate fix through nut; Described outer cover and outer ring fix, and the front end of described outer ring seals through last black box with the front end of inner ring mutually, seal mutually through the lower seal assembly between the rear end of described outer ring and the rear end of inner ring; The rear end sidewall of described outer ring is provided with dust ring, and described dust ring is corresponding with flange plate.
As preferably, the width of described outer ring is greater than the width of inner ring.
Therefore, the hub of the band double-sealing assembly of the utility model, simple in structure, installation precision is high, improves working life, and using effect is remarkable.
