Abstract

The utility model provides a light-weight hub, which comprises a hub body, wherein the hub body comprises a shell body part, two ends of the shell body part are respectively provided with a spoke fixing disk part, and a plurality of reinforcing ribs are arranged on the shell body part between the two spoke fixing disk parts; the utility model provides a lightweight flower-drum, under the circumstances of the shell body intensity of guaranteeing flower-drum, reduce the wall thickness of the shell body of flower-drum to reach the purpose that reduces flower-drum weight.

Description

Lightweight flower-drum

Technical Field

The utility model relates to a bicycle flower-drum technical field particularly, relates to a lightweight flower-drum.

Background

The hub is a bearing drum of a bicycle, as shown in fig. 1, the existing hub includes a shell body ' 1 and spoke fixing disk portions ' 2 respectively disposed at two ends of the shell body ' 1, the spoke fixing disk portions ' 2 of the hub play a role of connecting spokes, and the shell body ' 1 of the hub plays a role of supporting spokes, so that, in order to improve strength of the shell body ' 1 of the hub, the wall thickness of the shell body ' 1 is generally too large, the shell body ' 1 with too large wall thickness can cause the overall weight of the hub to be increased, and the weight of a vehicle body is also increased indirectly, but if the wall thickness is too small, the strength of the shell body ' 1 of the hub can be reduced, and there is also a safety hazard when in use, a lightweight hub made of a material combined with carbon fibers is adopted at present, but its cost and price are very high.

In view of the above, the inventor of the present application invented a light-weight hub.

Disclosure of Invention

The utility model provides a lightweight flower-drum, under the circumstances of the shell body intensity of guaranteeing flower-drum, reduce the wall thickness of the shell body of flower-drum to reach the purpose that reduces flower-drum weight.

The utility model discloses a realize like this:

the light-weight hub comprises a hub body, wherein the hub body comprises a shell body part, two spoke fixing disk parts are respectively arranged at two ends of the shell body part, and a plurality of reinforcing ribs are arranged on the shell body part between the spoke fixing disk parts.

Further, each reinforcing rib is arranged on the outer wall of the shell body part along the radial direction of the hub body at intervals.

Further, the distance between every two adjacent reinforcing ribs is smaller than the width of the reinforcing ribs.

Further, the number of the reinforcing ribs is at least five.

Furthermore, the shell body part, the two spoke fixing disk parts and the reinforcing ribs are integrally formed.

The utility model has the advantages that:

the utility model discloses after the wall thickness that reduces shell body portion, the strengthening rib can compensate the intensity of shell body loss to guarantee that the bulk strength of shell body portion is unchangeable, simultaneously, the weight of shell body portion and strengthening rib after reducing the wall thickness also is less than the weight of shell body portion before reducing the wall thickness, has reduced the holistic weight of flower-drum.

Description of the main elements

Shell body portion '1, spoke fixing disk portion' 2, flower-drum body 3, shell body portion 4, spoke fixing disk portion 5, strengthening rib 6.

Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined to clearly and completely describe the technical solutions of the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In the present disclosure, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact between the first and second features, or may comprise contact between the first and second features not directly. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

Example one

Referring to fig. 1 and 2, a lightweight flower-drum, including flower-drum body 3, flower-drum body 3 includes shell portion 4, shell portion 4 both ends are provided with a spoke fixing disk portion 5 respectively, spoke fixing disk portion 5 is used for connecting the spoke on the bicycle wheel, shell portion 4 plays the effect of supporting the spoke, be provided with a plurality of strengthening ribs 6 on shell portion 4 between two spoke fixing disk portions 5, every strengthening rib 6 all sets up on shell portion 4 outer wall along flower-drum body 3 radial interval, after reducing the wall thickness of shell portion 4, strengthening rib 6 can compensate the intensity of shell portion 4 loss, in order to guarantee that the bulk strength of shell portion 4 does not change, simultaneously, the weight of shell portion 4 and strengthening rib 6 after reducing the wall thickness also is less than the weight of shell portion 4 before reducing the wall thickness, the holistic weight of flower-drum has been reduced.

Further, the number of the reinforcing ribs 6 is at least five, so that the strength of the shell part 4 is ensured, the distance between every two adjacent reinforcing ribs 6 is smaller than the width of the reinforcing ribs 6, and the influence on the strength of the shell part 4 caused by the overlarge distance between the two adjacent reinforcing ribs 6 is prevented.

Furthermore, the shell body part 4, the two spoke fixing disc parts 5 and the reinforcing ribs 6 are integrally formed, and can be produced in batch by the same group of dies, so that the production cost is reduced.

Wherein, the strengthening rib 6 also can be set up on the outer wall of shell body portion 4 in cyclic annular or heliciform mode, and is not limited to the technical scheme mentioned in the utility model.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
