Abstract
The utility model relates to a hub unit, in particular to a hub unit with asymmetrical retainers and steel balls. The hub unit is used in an automobile. The hub unit comprises a flange plate with a shaft hole; an inner ring is sleeved on the head of the flange plate; an outer ring is sleeved outside the inner ring and the flange plate; a retainer passage is formed among the outer ring, the inner ring and the flange plate; an upper retainer is arranged on the head of the retainer passage; a lower retainer is arranged at the tail of the retainer passage; a steel ball is embedded into each of the upper retainer and the lower retainer; and the upper retainer and the lower retainer are distributed asymmetrically. The hub unit with the asymmetrical retainers and steel balls is simple in structure and high in installation precision, the service life is prolonged, the integral bearing rigidity of the hub unit is improved, and the braking performance is promoted.
Description
Technical field
The utility model patent relates to a kind of hub, relates in particular to the non-symmetrical hub of a kind of retainer and steel ball, 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.
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 outstanding retainer and the non-symmetrical hub of steel ball of result of use.
The above-mentioned technical matters of the utility model mainly is able to solve through following technical proposals:
The non-symmetrical hub of a kind of retainer and steel ball comprises the flange that has axis hole, and the head of described flange is with inner ring; Described inner ring and flange are with the outer ring outward; Described outer ring and inner ring and flange form the retainer passage, and the head of described retainer passage is provided with holder, and the afterbody of described retainer passage is provided with down retainer; Rabbeting respectively in described holder and the following retainer has steel ball, and described holder is a distribution or asymmetrical distribution with following retainer.
This structure relative compact, assembly precision is high simultaneously, and the simultaneous wheels hub unit has stronger leak tightness and water-proofness; Prolong the service life of retainer; Improve single-piece service property (quality) and service life, holder is a distribution or asymmetrical distribution with following retainer simultaneously, further improves the load-carrying capacity of flange raceway groove; Improve the integrated carrying rigidity of product, promote the deceleration and stopping performance of product.
As preferably, be provided with upper skeleton between described inner ring and outer ring, be provided with back seal spare in the described upper skeleton, described outer ring seals through lower seal with flange mutually.
As preferably, described outer ring is provided with three assembly openings that are uniformly distributed with, and described flange is provided with the bolt that is uniformly distributed with.
As preferably, described holder is located between inner ring and outer ring, and described retainer down is located between outer ring and flange.
The outer ring is a triangle, and 3 assembly openings are distributed on three angles.
Therefore, the non-symmetrical hub of retainer of the utility model and steel ball, simple in structure, setting accuracy is high, improves service life, improves product integrated carrying rigidity simultaneously, promotes deceleration and stopping performance.
