Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further described.

Referring to Fig. 1 , a bicycle front hub with a storage function of the utility model includes an outer hub 1, a plurality of bearing rollers 2, an inner hub 3, an access door 4 and two hub cover plates 5; wherein, the outer hub 1 The inner side of the inner hub 3 and the outer side of the inner hub 3 are respectively provided with a plurality of outer hub rolling grooves and inner hub rolling grooves for placing the bearing rollers 2, and several bearing rollers 2 are evenly arranged in the circumferential direction between the outer hub 1 and the inner hub 3 In some outer hub rolling grooves and inner hub rolling grooves, two hub cover plates 5 are arranged on both sides of the inner hub 3, and at least one hub cover plate 5 is provided with a pick-up door 4. Wherein, the surfaces of the rolling grooves of the outer hub and the rolling grooves of the inner hub are quenched to adapt to long-term rolling friction. The outer hub 1 and the inner hub 3 are connected by a number of bearing rollers 2 uniformly arranged in the circumferential direction to form a slewing bearing, so they can bear a certain comprehensive load such as axial load, radial load and overturning moment at the same time, forming a bearing similar to a slewing bearing The support rotation effect.

Further, two sides of the inner hub 3 are respectively provided with bayonet slots, and the two hub covers 5 are installed on the inner hub 3 through the bayonet slots.

Referring to Fig. 2a and Fig. 2b, the bearing rolling body 2 is a ball or a cylindrical rolling body.

Referring to Fig. 3, a single bearing roller 2 forms a rolling friction pair with the bearing outer sleeve clamping block 8 arranged in the rolling groove of the outer hub and the bearing inner sleeve clamping block 9 arranged in the rolling groove of the inner hub respectively, and the inside A positioning locking block 10 and a locking nut 11 for preventing the inner hub 3 from moving are also arranged in the rolling groove of the hub. Due to the addition of the lock nut 11, the axial displacement of the inner hub 3 can be effectively prevented.

During use, the front fork 7 of the bicycle is installed at both ends of the central axis of the inner wheel hub 3 by the fixing nut 6 .

Specifically, the utility model adds an inner wheel hub 3 inside the original bicycle front hub, and the front fork 7 of the bicycle is fastened on the inner wheel hub 3 through the fixing nut 6, and the original bicycle front wheel hub is rolled by a rolling bearing. The body 2 forms a rolling friction pair, so that the inner hub 3 no longer rotates with the bicycle riding; at the same time, two hub covers 5 are added to the two sides of the inner hub 3, thereby forming a storage space, the hub cover 5 There is a pick-up door 4 designed on the top that can be opened and closed, and the hub cover 5 is fixed through the bayonet designed on the inner hub 3, which can support the wheel and play the role of spokes (spokes), and can also be kept airtight without affecting riding safety . During use, the front fork 7 of the vehicle frame is fixedly connected to the inner hub 3, so that the inner hub 3 does not rotate with the bicycle riding.

The utility model not only has the function of an ordinary bicycle hub, but also can effectively use the space of the hub to store items without any influence on the bicycle riding safety.
