Abstract
The utility model relates to a hub unit, and particularly relates to a high-accuracy hub unit for a hub of an automobile. The high-accuracy hub unit comprises a ring flange of an assembly cavity, wherein an inner ring I and an inner ring II are respectively sequentially embedded into the ring flange; outer rings are sleeved outside the inner ring I and the inner ring II; rollers are respectively arranged between the inner ring I and the outer ring and between the inner ring II and the outer ring, and the rollers are positioned through retaining frames; a gear ring is sleeved outside the inner ring II, and the gear ring is arranged between the rollers; and sensors communicated with the outer rings are spliced in the outer rings. The high-accuracy hub unit disclosed by the utility model has the advantages of compact structure, enhanced assembly accuracy and prolonged service life.
Description
Technical field
The utility model is a kind of hub, and particularly a kind of highi degree of accuracy hub is used for the wheel hub of automobile.
Background technique
Hub structure relative complex of the prior art, and assembly precision is lower, and using effect is unoutstanding simultaneously.
Chinese patent 200420119173.7 discloses a kind of hub with bearing, comprises flange plate, it is characterized in that described flange plate is provided with bearing support outward, is provided with two single-row conical bearings between flange plate and the bearing support; Flange plate 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 support 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 using effect is relatively poor, and working life is shorter simultaneously.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, compact structure, and installation precision is high simultaneously, the highi degree of accuracy hub that increases the service life.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of highi degree of accuracy hub, the flange plate that comprises assembly cavity, embed successively respectively on the described flange plate inner ring I and inner ring II are arranged, described inner ring I and inner ring II overcoat have the outer ring, between described inner ring I and outer ring, be respectively equipped with roller between inner ring II and outer ring, described roller is located mutually by retainer, and described inner ring II overcoat has gear ring, described gear ring is located between roller, is plugged with in the described outer ring to be attached thereto logical sensor.
As preferably, between described inner ring I and outer ring, seal mutually respectively the head end of described sensor and the corresponding distribution in the exterior edge face of gear ring by seal ring between inner ring II and outer ring.
As preferably, described flange plate is provided with equally distributed pilot hole, and described outer ring is provided with positioning hole, the perpendicular distribution in described sensor and outer ring.
Therefore, a kind of highi degree of accuracy hub that the utility model provides, compact structure improves assembly precision, promotes working life.
