Abstract
The utility model relates to a wheel hub, in particular to a wheel hub with a gear ring located in a narrow inner ring. The wheel hub unit with the gear ring located in the narrow inner ring is used for a wheel hub of an automobile and comprises a flange plate. The narrow inner ring and a wide inner ring are sequentially arranged outside the flange plate in a sleeved mode. An outer ring is sleeved outside the narrow and wide inner rings. Rollers are respectively arranged between the narrow inner ring and the outer ring and between the wide inner ring and the outer ring. The rollers are mutually positioned through a holder. A gear ring is sleeved outside the narrow inner ring, the gear ring is located between the rollers, and a front assembly groove is formed in the head portion of the flange plate. A rear assembly groove is formed in the tail portion of the flange plate, and sensors distributed in an inclined mode are connected in the outer ring in an inserted mode. According to the wheel hub with the gear ring located in the narrow inner ring, structure is compact, assembly accuracy is improved, and service life is prolonged.
Description
Technical field
The utility model is a kind of hub, and particularly a kind of gear ring is positioned at the hub of narrow inner ring, is used for the wheel hub of automobile.
Background technology
Hub structure relative complex of the prior art, and assembly precision is lower, and result of use is unoutstanding simultaneously.
Chinese patent 200420119173.7 discloses a kind of hub with bearing, comprises flange, it is characterized in that described flange is provided with bearing seat outward, is provided with two single-row conical bearings between flange and the bearing seat; Flange is provided with back-up ring near the axle journal outer radius of small end face, and the back-up ring end face compresses the large end face of bearing one inner ring; Bearing seat internal diameter both sides are provided with seal ring, and its outside internal diameter contacts with the flangeseal step, and inboard internal diameter contacts with the external diameter of back-up ring.This structure relative complex, and result of use is relatively poor, and service life is shorter simultaneously.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, compact conformation, and setting accuracy is high simultaneously, and the gear ring that increases the service life is positioned at the hub of narrow inner ring.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A kind of gear ring is positioned at the hub of narrow inner ring, comprise flange, described flange overlaps respectively outward successively narrow inner ring and wide inner ring, described narrow inner ring and wide inner ring overcoat have the outer ring, between described narrow inner ring and outer ring, be respectively equipped with roller between wide inner ring and outer ring, described roller is located mutually by retainer, described narrow inner ring overcoat has gear ring, described gear ring is positioned between roller, be provided with front fitting recess in the head of described flange, be provided with rear fitting recess in the afterbody of described flange, be plugged with the sensor of tilt distribution in the described outer ring.
As preferably, between described narrow inner ring and outer ring, seal mutually by seal ring respectively between wide inner ring and outer ring, the end face of described gear ring outer wall is corresponding with the end face of sensor head.
As preferably, described flange is provided with the well-distributed assembly opening, and described outer ring is provided with 4 well-distributeds assembling knuckles, and described assembling knuckle is provided with the knuckle knock hole.
As preferably, described sensor and outer ring are by the mutually sealing of O shape circle.
Therefore, the gear ring that the utility model provides is positioned at the hub of narrow inner ring, and compact conformation improves assembly precision, promotes service life.
