In such scheme, described front-wheel wheel shaft can have the front-wheel central siphon by bearing installation, and described front-wheel can be to be fixedly attached on the front-wheel central siphon by nut; Described rear axle can have the trailing wheel central siphon by bearing installation, and described trailing wheel can be to be fixedly attached on the trailing wheel central siphon by nut; One end of described trailing wheel central siphon can be equipped with flywheel; Between the wheel hub of described front-wheel central siphon and front-wheel be connected and the wheel hub of described trailing wheel central siphon and trailing wheel between to be connected can be that key connects, it can be to be provided with spline on front-wheel central siphon and trailing wheel central siphon that described key connects, and the wheel hub of front-wheel and the wheel hub of trailing wheel have the keyway that adapts with described spline.
Owing to adopted such scheme, the utility model compared with prior art has following beneficial effect:
1, wheel is changed easily.Owing to be equipped with turning joint on the side yoke of front fork and on the side yoke of back vent, no matter be any one when being damaged or blowing out of front-wheel or trailing wheel, only need unclamp the yoke that is provided with turning joint is fastened on nut on the wheel shaft, just can outwards open yoke, make wheel can take out replacing from the side, do not need vehicle body is propped up and the removing vehicle tyres wheel shaft.
2, bicycle wheels is general.Owing to all adopting spline to be connected between front-wheel hub and the front-wheel central siphon and between trailing wheel central siphon and the rear wheel hub, and flywheel can be installed on the trailing wheel central siphon, so reserve wheel is can front and back wheel general.
3, on vehicle frame, be provided with the hook of suspended wheel, when going out by bike, hang Das Reserverad with car, can instantaneously changing, conveniently use in case meet accident.
