Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The wheel mounting structure of the bicycle shown in fig. 1 includes a single fork 1, a fixed shaft 2, a hub 3, and a wheel 4. Wherein, the fixed shaft 2 is detachably fixed on the single fork 1; the hub 3 is circumferentially rotatable and axially immovable relative to the fixed shaft 2, and a side thereof away from the single fork 1 is provided with a first connecting part 31; wheel 4 detachably is fixed in the first connecting portion 31 of flower-drum 3, in this embodiment, first connecting portion 31 is the flange, and a plurality of screws that wheel 4 set up through the circumference array are installed on first connecting portion 31, like this when wheel 4 is pulled down to needs, only need pull down the screw and can take off the wheel, convenient and fast.

The single fork 1 is provided with a mounting hole 11; the fixed shaft 2 is provided with a limiting section 21, a front fork matching section 22 and a hub matching section 23 which are sequentially arranged in an adjacent mode; the front fork matching section 22 is matched with the mounting hole 11, and the limiting section 21 is abutted against the single fork 1; a plurality of bearings 5 are arranged between the hub matching section 23 and the hub 3; and a fastener 6 for axially fixing the fixed shaft 2. Specifically, in the present embodiment, the fixing shaft 2 is further formed with a fastener fitting section 24 adjacent to the hub fitting section 23; the fastening member 6 is a nut screwed on the fastening member fitting section 24 and abuts against an inner ring of a bearing 5.
