Abstract
The utility model provides a hub portion structure of a hub of a motorcycle wheel. The hub portion structure of the hub of the motorcycle wheel enables the stress of the hub portion not to be concentrated on a certain position during braking, and ensures safety. In addition, manufacturing materials are saved, and manufacturing cost is low. The hub portion structure of the hub of the motorcycle wheel comprises a large side circular face and a small side circular face, and is characterized in that the large side circular face and the small side circular face are connected through an outer circular conical surface of a circular cone platform, and the interior formed by the large side circular face, the small side circular face and the outer circular conical surface is a hub portion installing cavity.
Description
Technical field
The utility model relates to the technical field of motorcycle wheel construction, is specially a kind of hub portion structure of wheel hub of bike wheel.
Background technology
The hub portion of the wheel hub of the bike wheel of aluminum, because the installation parts of its two sides are different, therefore the disc of a side is large, the disc of opposite side is little, the connection structure of an existing side and another side is stair-stepping boss structure (seeing Fig. 1), because there is obvious demarcation line at the middle part of boss structure, it makes when brake, and the power of generation is concentrated in this place, demarcation line, the stress at this place is concentrated, dangerous; In addition,, when boss structure is manufactured, the material needing is many, causes cost of manufacture high.
Summary of the invention
For the problems referred to above, the utility model provides a kind of hub portion structure of wheel hub of bike wheel, and when it makes to brake, the stress of hub portion does not concentrate on a certain position, guarantees safety; In addition, save manufactured materials, made cost of manufacture low.
A kind of hub portion structure of wheel hub of bike wheel, its technical scheme is such: it comprises large side disc, little side disc, it is characterized in that: the outer conical surface by the frustum of a cone between described large side disc and little side disc connects, the inside that described large side disc, little side disc, outer conical surface three form is hub portion installation cavity.
Adopt after structure of the present utility model, because the outer conical surface by the frustum of a cone between large side disc and little side disc connects, it makes the formation continuity transition between large side disc, little side disc, and while making to brake, the stress of hub portion does not concentrate on a certain position, guarantees safety; In addition, the whole area of the outer conical surface of the frustum of a cone is less than the entire area of original boss structure, has saved manufactured materials, makes cost of manufacture low.
Accompanying drawing explanation
Fig. 1 is the hub portion structure of the wheel hub of existing bike wheel;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
See Fig. 2, it comprises large side disc 1, little side disc 2, and the outer conical surface 3 by the frustum of a cone between large side disc 1 and little side disc 2 connects, and the inside that large side disc 1, little side disc 2, outer conical surface 3 threes form is hub portion installation cavity 4.
