Utility model content
The purpose of this utility model is to provide a kind of bicycle main driving wheel, asked with solve to propose in above-mentioned background technology
Topic.
The purpose of this utility model is achieved by following technical proposals：A kind of bicycle main driving wheel, including gear
Disk, support frame, annulus, sleeve, fixing device, pedal arm, cap bag, bolt, nut, pad, the toothed disc and some supports
Frame one end is connected, and the support frame as described above other end is connected with annulus, and rotating shaft built in annulus, is provided between the annulus and rotating shaft
Rolling bearing, sleeve is installed in the rotating shaft, some through holes are provided with the sleeve, and pedal arm is provided with sleeve, it is described
Circular hole corresponding with the through hole on sleeve is provided with pedal arm, fixation is installed in the through hole of the sleeve and the circular hole of pedal arm
Device, the fixing device include bolt, nut and pad, and the end surfaces of bolt two are provided with screw thread, and among bolt
Column part is located in through hole with sleeve, and the bolt left and right ends are mounted on nut, and pad is provided between nuts and bolt
Piece, the sleeve right-hand member are provided with cap bag.
Further, the through-hole diameter size of described sleeve and the Circularhole diameter size of pedal arm are identical.
Further, the cap bag is cylindrical, and cap bag inner hollow, and cap bag is made up of elastomeric material.
Further, the number of openings of described sleeve is 2-3.
Further, the circular hole quantity of described pedal arm is 3-4.
Compared with prior art, the beneficial effects of the utility model are new a kind of bicycle main driving wheels, thus it is possible to vary
The single present situation of market bicycle main driving wheel, meanwhile, bicyclist can adjust pedal arm according to the comfort level that oneself is ridden
Length, labour-saving effect can also be reached, sleeve be free to assembly and disassembly with pedal arm, and convenient schedule to last is cleared up, increase
Cap bag can prevent dust from entering with rainwater in the gap of sleeve and pedal arm, and this is the design for comparing rationalization.
