Abstract
The utility model relates to a hub unit, in particular to an asymmetric conical hub unit. The hub unit is used for automobiles. The asymmetric conical hub unit comprises inner rings. Outer rings are respectively sheathed outside the inner rings; a retainer channel is formed between each inner ring and the corresponding outer ring; a pair of retainers symmetrically distributed at intervals is arranged in each retainer channel; rollers are respectively arranged in the retainers; and gear rings are respectively sheathed at the tail parts of the outer rings. The asymmetric conical hub unit has the advantages that the structure is simple, the installation accuracy is high and the service life is prolonged.
Description
Technical field
The utility model patent relates to a kind of hub, relates in particular to a kind of asymmetric conical wheel hub unit, and hub is used for automobile.
Background technique
Present automobile hub unit of the prior art, 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 outstanding asymmetric conical wheel hub unit of using effect.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of asymmetric conical wheel hub unit; Comprise inner ring; Described inner ring is with the outer ring outward, forms the retainer passage between described inner ring and outer ring, is provided with the retainer that the pair of spaced symmetry shape distributes in the described retainer passage; Be provided with roller in the described retainer, the afterbody of described outer ring is with gear ring.
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, be provided with upper skeleton between described inner ring and outer ring, be provided with Sealing in the described upper skeleton, described outer ring seals through lower seal with flange plate mutually.
As preferably, described inner ring comprises left inner ring and right inner ring, and described left inner ring and right inner ring are through snap close interlocking mutually; Described snap close is located in the inner ring; Be provided with oil layer between described left inner ring and outer ring, be provided with skeleton between described right inner ring and outer ring, be provided with Sealing in the described skeleton.
As preferably, described outer ring is provided with equally distributed pilot hole, and the spacing angle between described pilot hole is 36 degree.
As preferably, the width of described inner ring equals the outer ring width, the distribution that aligns of described inner ring and outer ring.
Therefore, a kind of asymmetric conical wheel hub unit of the utility model, simple in structure, installation precision is high, improves working life.
