Detailed Description
The utility model provides a bicycle hub, only change axle core and side cap and just can cooperate the scooter or the bicycle of different specifications to use, reduction in production cost. The invention is described in detail below with reference to the drawings and the detailed description.
As shown in fig. 1 and 4, the bicycle hub of the present invention comprises a hub 30, the hub 30 is hollow, and a shaft core 40 is inserted into the hub 30.
The upper portion of the axle core 40 is equipped with first annular boss 41, and the middle part is equipped with second annular boss 42, and the upper portion suit first bearing 20 of second annular boss 42, the lower part suit second bearing 21 of axle core 40, and first annular boss 41 block is in the upper end of first bearing, because first bearing 20 suit is on second annular boss 42, so the internal diameter of first bearing 20 is bigger than the internal diameter of second bearing 21.
The hub body 30 is an inwardly recessed arc-shaped cylinder, a first clamping groove 31 and a second clamping groove 32 are formed in the hub body, the first bearing 20 and the second bearing 21 are respectively clamped and fixed, the upper end circumference and the lower end circumference of the hub body 30 are provided with round holes which are uniformly distributed, and spokes on a wheel are inserted into the round holes.
The shaft core 40 is a hollow structure, the upper end part of the shaft core is provided with a detachable first side cover 10, the lower end part of the shaft core is provided with a detachable second side cover 11, the upper end of the inner part of the shaft core is inserted with a stud 50 with internal threads, the lower end of the shaft core is provided with a screw 51 matched with the stud 50, and the two are screwed and connected to fix the whole hub.
