Abstract
The utility model relates to a bicycle and by feet rearward rotating crank arms drives the rear wheel spindle to speed-up and rotate the rear wheel through the central gear. The spindle is arranged on the bicycle frame by bearing and the crank arms and the outer central gear are arranged on the spindle. The faceplate is arranged on the spindle with the bearing and the bracket is provided at the bicycle frame. The intermediate gear is looped on the bracket. One end of the inner central gear is provided with a clutch which is looped on the spindle with shaft sleeve and clutches on-off with the faceplate. The rear wheel can be rotated to move forward when the faceplate is closed. The bicycle is compact in structure and high in transmission efficiency, which solves the difficult problems of dispensing structure of the bicycle, looseness of the chain and low transmission efficiency.
Description
The utility model relates to a kind of pin crank that rotates backward and drives hind axle rotates trailing wheel through the sun gear speedup bicycle.
At present, the bicycle of generally acknowledging be crank in the centre, rotate trailing wheel through chain and travel forward, its structure is disperseed, chain is easily loosening, driving efficiency is low.
The purpose of this utility model provides a kind of compact conformation, bicycle that driving efficiency is high.
The purpose of this utility model is achieved in that axle is contained on the vehicle frame with bearing, crank and outer sun gear are contained on the axle, floral disc is contained on the axle with bearing, support is contained on the vehicle frame, the intermediate gear kink is on support, interior sun gear one end be provided with power-transfer clutch with the axle sleeve kink on axle with the floral disc clutch, the floral disc that closes rotates trailing wheel and travels forward.The ratio of number of teeth of sun gear is exactly the speed ratio of crank and trailing wheel.
Owing to adopt such scheme, make the bicycle structure compactness, reliable, the driving efficiency height.And can shorten the distance of trailing wheel and front-wheel, reduce the volume of bicycle.The moment that helps the leg muscle motion simultaneously reaches crank, makes the cyclist comfortable laborsaving.
Below in conjunction with drawings and Examples, the utility model is further specified.
Figure is the elevation profile organigram of the utility model embodiment.
Among the figure: 1, crank 2, axle 3, outer sun gear 4, support 5, intermediate gear 6, interior sun gear 7, power-transfer clutch 8, axle sleeve 9, floral disc 10, vehicle frame 11, bearing, in the drawings, axle 2 usefulness bearings 11 are contained on the vehicle frame 10, crank 1 and outer sun gear 3 are contained on the axle 2, floral disc 9 usefulness bearings 11 are contained on the axle 2, support 4 is contained on the vehicle frame 10, intermediate gear 5 kinks on support 4, interior sun gear 6 one ends be provided with power-transfer clutch 7 usefulness axle sleeves 8 kinks on axle 2 with floral disc 9 clutches.When the pin crank 1 that rotates backward, axle 2 and outer sun gear 3 rotate together, sun gear 6 and power-transfer clutch 7 rotate forward in intermediate gear 5 rotates, the floral disc 9 that closes rotates trailing wheel and travels forward, when foot-rest is motionless, be rotated further by force of inertia floral disc 9 overriding clutchs 7, thus sliding when realizing stopping pin.
