Abstract
The utility model relates to a hub unit, in particular to a hub unit with a driving spline groove. The hub unit is used in an automobile. The hub unit comprises a flange plate with a shaft hole; a wide inner ring and a narrow inner ring are sleeved on the flange plate; an outer ring is sleeved outside the wide inner ring and the narrow inner ring; a retainer passage is formed among the outer ring, the wide inner ring and the narrow inner ring; a pair of retainers distributed symmetrically at interval is arranged in the retainer passage; a roller is arranged in each retainer; a needle rolling bearing is arranged in the shaft hole of the flange plate; the wide inner ring and the narrow inner ring are locked with the flange plate through a nut; a lock catch is clamped on the nut; and the tail of the flange plate is provided with the spline groove. The hub unit with the driving spline groove is simple in structure and high in installation precision, the service life is prolonged, and switching of driving modes is increased.
Description
Technical field
The utility model patent relates to a kind of hub, relates in particular to a kind of hub with the driving spline, 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 the outstanding band of result of use drives the hub of spline.
The above-mentioned technical matters of the utility model mainly is able to solve through following technical proposals:
A kind of hub with the driving spline comprises the flange that has axis hole, 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 the retainer that pair of spaced is symmetrically distributed in the described retainer passage, be provided with roller in the described retainer; Be provided with needle bearing in the axis hole of described flange; Described wide inner ring is locked with flange through nut with narrow inner ring mutually, is connected with snap close on the described nut, and the afterbody of described flange is provided with spline.
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, be provided with spline, drive the switching of driving pattern to 2 with 4 to realizing at the afterbody of flange.
As preferably, described wide inner ring supports through left skeleton with the outer ring mutually, is provided with left sealing member in the described left skeleton, and described narrow inner ring supports through right skeleton with the outer ring mutually, is provided with right sealing member in the described right skeleton.
As preferably, described wide inner ring and narrow inner ring parallel splicing, and described outer ring is provided with three assembly openings that are uniformly distributed with mutually, is evenly equipped with bolt on the described flange.
The outer ring is a triangle, and 3 assembly openings are distributed on three angles.
Therefore, the band of the utility model drives the hub of spline, and is simple in structure, and setting accuracy is high, improves service life, increases drive pattern and switches.
