The utility model aims at providing a motorcycle wheel hub, its is rational in infrastructure, can save the raw materials quantity under the condition of not reducing the intensity through set up a plurality of sunkens on connecting the face, alleviates product weight, reduction in production cost is convenient for install and move.

The technical proposal for realizing the purposes of the utility model is that

The motorcycle hub comprises a hub body which is integrally manufactured, wherein the periphery of the hub body is provided with two connecting discs which are arranged at intervals along the axial direction, one end face of the hub body is a connecting face which is connected with a hub support, a sleeve portion is arranged at the center of the hub body, the corresponding outer end of the sleeve portion protrudes out of the connecting face, and a plurality of depressions are uniformly distributed on the connecting face along the circumferential direction.

In the technical scheme, the side surface of the hub body is provided with the open groove communicated with the recess.

In the technical scheme, a plurality of notches are uniformly distributed on the outer periphery of the connecting disc along the circumferential direction.

In the technical scheme, a plurality of connecting holes are formed in the connecting disc at intervals along the circumferential direction.

In the technical scheme, the notches are arc notches, the outer edges of the two adjacent arc notches are in smooth transition to form arc protrusions, the number of all the arc protrusions is equal to that of the connecting holes, and the connecting holes are arranged at the arc protrusions in a one-to-one correspondence mode.

In the above technical scheme, the connecting hole is a stepped hole.

In the technical scheme, the connecting surface is uniformly provided with screw holes along the circumferential direction.

The utility model discloses has positive effect: the utility model provides a motorcycle wheel hub is rational in infrastructure, sets up a plurality of sunken economize in the raw materials quantity under the condition of not reducing the intensity through to structural optimization connecting the equipartition in week, alleviates product weight, and reduction in production cost is convenient for install and move.

The attached figures shown in the figures are: 1-a hub body; 11-connecting surface; 12-a sleeve portion; 121-concave; 122-slotting; 2-a connecting disc; 21-a notch; 22-connecting hole; 23-arc-shaped bulge.

Detailed Description

The structure of the motorcycle hub in the present invention is described below with reference to the drawings of the specification:

a motorcycle wheel hub is shown in figures 1 to 3 and comprises a wheel hub body 1 which is integrally manufactured, wherein two connecting discs 2 which are arranged at intervals along the axial direction are arranged on the periphery of the wheel hub body 1, one end face of the wheel hub body 1 is a connecting face 11 which is connected with a wheel hub support, a sleeve portion 12 is arranged in the center of the wheel hub body 1, the corresponding outer end of the sleeve portion 12 protrudes out of the connecting face 11, and a plurality of recesses 121 are uniformly distributed on the connecting face 11 along the circumferential direction. The utility model provides a motorcycle wheel hub is rational in infrastructure, sets up a plurality of sunken 121 along circumference promptly on connecting face 11 through configuration optimization and save material under the condition of not reducing the intensity, alleviates product weight, reduction in production cost, the product installation of also being convenient for and moving.

As a further optimized solution of this embodiment, a slot 122 communicating with the recess 121 is formed on the side surface of the hub body 1, and by providing the slot, material can be further saved, and impurities that may enter the recess 121 during use can be discharged from the slot 122.

In this embodiment, the outer peripheral edge of connection pad 2 is equipped with a plurality of breachs 21 along circumference equipartition, forms the aesthetic property that the lace has increased the product at connection pad 2 periphery through setting up breach 2 to compare the circular periphery of connection pad 2, the existence of breach 21 can disturb the air help heat dissipation when wheel hub rotates.

Further, a plurality of connecting holes 22 are formed in the connecting disc 2 at intervals in the circumferential direction, when the hub assembly is assembled, one end of each spoke is bent into a right angle and then penetrates through the connecting holes, a limiting end is manufactured at the end of each spoke to prevent the spoke from being separated from the connecting holes, the connecting holes 22 are preferably stepped holes, and the large-bore ends of the stepped holes can be suitable for accommodating the limiting ends.

Still further, as shown in the figure, the notches 21 are arc notches, the outer edges of the protrusions between two adjacent arc notches are in smooth transition to form arc protrusions 23, the number of all the arc protrusions 23 is equal to that of the connecting holes 22, and the connecting holes 22 are correspondingly arranged at the arc protrusions 23 one by one, specifically referring to fig. 1, so that the appearance of the hub is more attractive.

The screw holes are uniformly distributed in the circumferential direction on the connecting surface 11, when the hub and the hub support are assembled, the connecting surface 11 at the end part of the hub is attached to the corresponding side surface of the hub support, screw through holes in the hub support are aligned with the screw holes in the connecting surface 11 one by one, and then the screws penetrate through the screw through holes and are in threaded connection with the screw holes to complete fixed connection.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not limitations to the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And such obvious changes and modifications which fall within the spirit of the invention are deemed to be covered by the present invention.
