Abstract
The utility model provides a hub unit and particularly relates to a compact hub unit used in the automobile hub field. The compact hub unit comprises a flange plate with an assembling cavity. A narrow inner ring and a wide inner ring which are sequentially distributed are embedded outside the flange plate. Outer rings are sleeved outside the narrow inner ring and the wide inner ring. 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 located through retainers. A gear ring sleeved on the narrow inner ring is arranged between the rollers. A sensor is connected with the outer rings in an inserted mode and distributed in an inclined mode with the outer rings. The end face of the head portion of the sensor and the external end face of the gear ring are correspondingly distributed. Four assembling folded angles evenly distributed are arranged on the outer rings. Transition between the assembling folded angles and the outer rings is achieved through inner concave arcs. The compact hub unit is compact in structure, improves assembling precision and prolongs service life.
Description
Technical field
The utility model is a kind of hub, and particularly a kind of hub of close-coupled 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, the hub of the close-coupled that increases the service life.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A kind of hub of close-coupled, comprise the flange with assembly cavity, the outer embedding of described flange has narrow inner ring and the wide inner ring that distributes successively, 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, cover has gear ring on the described narrow inner ring, described gear ring is positioned between roller, be plugged with the sensor that tilts with it distribution on the described outer ring, the end face of the head of described sensor and the corresponding distribution of the outer face of gear ring, described outer ring is provided with 4 well-distributed assembling knuckles, and described assembling knuckle passes through the transition of imploded arcs phase with the 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, described sensor and outer ring are by O shape circle location mutually.
As preferably, described flange is provided with 8 well-distributed assembly openings, is provided with knock hole in the described assembling knuckle.
Therefore, the hub of a kind of close-coupled that the utility model provides, compact conformation improves assembly precision, promotes service life.
