Abstract
The utility model provides a wheel hub unit, and particularly relates to the wheel hub unit with an assembly tooth mechanism, wherein the wheel hub unit is used for automobile hubs. The wheel hub comprises a flange plate provided with an assembly cavity, assembly teeth which are evenly distributed are installed inside the assembly cavity, an outer ring is sleeved outside the flange plate, an inner ring is installed between the outer ring and the head portion of the flange plate, and steel balls are respectively installed between the inner ring and the outer ring and between the outer ring and the tail portion of the flange plate. A tooth ring is installed among the steel balls, the tooth ring is connected with the flange plate in a sleeved mode, a sensor is inserted into the outer ring and is extended out of the outer ring, the sensor and the outer ring are distributed correspondingly, and the steel balls are located through a retainer. The wheel hub unit with the assembly tooth mechanism is compact in structure, 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 hub with the assembling gear mechanism 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 band assembling gear mechanism 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 with the assembling gear mechanism, comprise the flange with assembly cavity, be provided with well-distributed assembling tooth in the described assembly cavity, described flange overcoat has the outer ring, be provided with inner ring between described outer ring and flange head, between described inner ring and outer ring, be respectively equipped with steel ball between outer ring and flange afterbody, be provided with gear ring between described steel ball, described gear ring and flange socket-connect, be plugged with sensor in the described outer ring and extend the outer ring, the corresponding distribution with gear ring of described sensor, described steel ball is located mutually by retainer.
This structure is so that assembly precision is high, easy for installation, structure relative compact simultaneously, and seal degree is high.
As preferably, seal mutually by front seal ring between described inner ring and outer ring, seal mutually by rear seal ring between described flange and outer ring.
As preferably, described flange is provided with assembly opening, and the edge of described outer ring is provided with three phase well-distributed knuckles, is provided with outer circle hole in the described knuckle,
As preferably, described sensor is located at the outer wall of outer ring, and described sensor seals by O type circle mutually with the outer ring, the end face of described sensor head and the corresponding distribution of the outer face of gear ring.
Therefore, the hub of the band assembling gear mechanism that the utility model provides, compact conformation improves assembly precision, promotes service life.
