Abstract
A motorcycle wheel hub is provided, which comprises a brake drum, a wheel hub body and an embedding sleeve positioned inside the wheel hub body. A bearing is installed by compression into the embedding sleeve. Such a structure of the utility model can greatly reduce the difference of rigidity and density between the bearing and the surface of the bearing installation hole, resolve the problem of loosening bearing and wheel hub, ensure the safety and comfort of riding and realize simple structure and convenient processing.
Description
Technical field
The utility model relates to a kind of hub of motorcycle.
Background technology
Its structure of hub of motorcycle of domestic production at present normally is made up of hub body and brake wheel.Behind the wheel hub pressing bearing, refill and join Tire ﹠ Tube and just constitute wheel, this structure since in use because of road surface or other factors under the effect of repeated stock power, because of outside race and aluminum alloy inner ring nonhomogeneous hardness bigger, and cause hub body pressing bearing bore deformation, aperture to increase, cause bearing to produce axle, radial-play, in use easily cause traffic safety accident and influence to drive traveling comfort, and change that to repair frequency higher.
Summary of the invention
For overcoming defective of the prior art, the utility model provides a kind of new wheel hub structure, can fundamentally solve the problem of bearing hole distortion and bearing play, can guarantee travel safety and drive traveling comfort.
The technical scheme that the utility model technical solution problem is adopted is: hub of motorcycle comprises brake wheel and hub body, and is provided with one nested in described hub body.Described nested can being cast as one with hub body also can be attached thereto in the mode of transition fit or close fit, or adopts other mode that can realize that circumferential and axial are located simultaneously to connect.When nested and hub body are cast as one, adopt schematic structure; When the mode that adopts transition fit or close fit is attached thereto, or when adopting other mode that can realize that circumferential and axial are located simultaneously to connect, the inner hole structure of hub body should change synchronously.After machine added, in nested, this structure can obviously reduce the difference of hardness and the density contrast of bearing and bearing press mounting hole surface, can guarantee its assembling and reliability of service with bearing press mounting.
The beneficial effects of the utility model are to solve wheel hub and the loosening problem of bearing, guarantee the safety and the traveling comfort that drive, and simple in structure, are easy to processing, and the while can significantly reduce repairing of these parts and change frequency, and favorable economic benefit and social benefit are arranged.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a constructional drawing of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
1. brake wheels among the figure, 2. hub body, 3 is nested.
The specific embodiment
Hub of motorcycle in Fig. 1 comprises brake wheel (1) and hub body (2), is provided with one nested (3) in described hub body (2).Nested (3) are foundry goods, and there is boss on its surface, must be after crash handling behind its casting forming, and again brake wheel (1) and nested (3) are installed in to press-fit and are cast on the mould in the hub body (2).
Claims (4)
1, a kind of hub of motorcycle comprises brake wheel (1) and hub body (2), it is characterized in that: be provided with one nested (3) in the described hub body (2).
2, hub of motorcycle according to claim 1 is characterized in that: described nested (3) are provided with boss with the contact surface of described hub body (2).
3, hub of motorcycle according to claim 1 and 2 is characterized in that: described nested (3) are cast as one with described hub body (2).
4, hub of motorcycle according to claim 1 and 2 is characterized in that: adopt transition fit or close fit or other mode that can realize that circumferential and axial are located simultaneously to be connected between described nested (3) and the institute's hub body (2).
