Abstract
The utility model provides a wheel hub unit, and particularly relates to the wheel hub unit with a flange plate provided with arc-shaped notches, wherein the wheel hub unit is used for automobile hubs. The wheel hub unit comprises the flange plate provided with an assembly cavity, a stepped assembly cavity is installed at the front end of the assembly cavity, assembly teeth are installed in the middle of the assembly cavity, and a close-fitting groove is formed in the rear end of the assembly cavity. An inner ring is installed outside the flange plate, an outer ring is sleeved outside the inner ring and the flange plate, steel balls are respectively installed between the inner ring and the outer ring and between the outer ring and the flange plate, the steel balls are located through a retainer, and the arc-shaped notches are evenly distributed in the edge of the flange plate. The wheel hub unit with the flange plate provided with the arc-shaped notches is compact in structure, assembly precision 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 arc notch flange 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 with the arc notch flange 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 arc notch flange, comprise the flange with assembly cavity, the front end of described assembly cavity is provided with the ladder assembly cavity, the middle-end of described assembly cavity is provided with the assembling tooth, the rear end of described assembly cavity is provided with the close-fitting groove, described flange is provided with inner ring outward, described inner ring and flange overcoat have the outer ring, between described inner ring and outer ring, be respectively equipped with steel ball between outer ring and flange, described steel ball is located mutually by retainer, and the edge of described flange is provided with the well-distributed arc notch.
As preferably, between described outer ring and inner ring, locate mutually by seal ring respectively between outer ring and flange, the head of described outer ring is to the inner ring extension.
As preferably, described flange is provided with assembly opening, and described arc notch is 5, and described outer ring is provided with 4 assembling knuckles, is provided with knock hole in the described assembling knuckle.
Therefore, the hub with the arc notch flange that the utility model provides, compact conformation improves assembly precision, promotes service life.
