Abstract

The utility model relates to a gearless speed-increasing power-assisted vehicle, which mainly solves the problems that a speed changing vehicle which has complicated structure and inconvenient use needs often gear shifting. The utility model is characterized in that a chainwheel which is fixed on a shaft of a foot board is connected with a flywheel on a speed-increasing wheel via a chain; the flywheel on the speed-increasing wheel is fixed on the speed-increasing wheel which is fixed with the shaft of the speed-increasing wheel via a bearing; the shaft of the speed-increasing wheel is fixed on a vehicle body via a connecting rod; the speed-increasing wheel is connected with the flywheel of a rear shaft via another chain; the flywheel of the rear shaft is fixed on the shaft of a rear wheel. The utility model can be used for bicycles, tricycles and four-wheel vehicles.

Description

A kind of nothing shelves speedup boosted vehicle
The utility model relates to a kind of nothing shelves speedup boosted vehicle.
In prior art; general derailleur is in order to reach not only soon but also the labour-saving purpose adopts a plurality of flywheels; when contrary wind or up-hill journey, adopt slow flywheel to reach the labour-saving purpose; when scanning frequency under general situation, adopt high-revolving flywheel to reach the purpose of fast running; the structure more complicated of this derailleur; and need frequent gear shift, use inconvenient.
The purpose of this utility model provides a kind of simple in structure, fast scanning frequency and no shelves speedup boosted vehicle easy to use.
The utility model is made up of chain, sprocket wheel, multiplying wheel and flywheel, it is characterized in that: sprocket wheel is fixed on the stretcher axis, sprocket wheel links to each other with flywheel on the multiplying wheel by chain, flywheel on the multiplying wheel is fixed on the multiplying wheel, multiplying wheel fixes by bearing and speedup wheel shaft, the speedup wheel shaft is fixed on the vehicle body by connecting rod, and multiplying wheel links to each other with rear flywheel by another chain, and rear flywheel is fixed on the hind axle.
Because the utility model sprocket wheel is by the flywheel on the chain drive multiplying wheel; flywheel on the multiplying wheel drives multiplying wheel; multiplying wheel drives rear flywheel by another chain, rotates thereby drive trailing wheel, like this; the rotation of sprocket wheel drives trailing wheel by twice speed change and rotates; so the utility model structure is very simple, can fast running laborsaving again, again because the utility model does not have gear; do not need frequent gear shift, so use easily.
Below in conjunction with accompanying drawing the utility model is elaborated,
Fig. 1 is the structural representation of the utility model embodiment,
Fig. 2 is the structural representation of another embodiment of the utility model,
With reference to Fig. 1, sprocket wheel 1 is fixed on the stretcher axis, sprocket wheel links to each other with flywheel 4 on the multiplying wheel 3 by chain 2, flywheel on the multiplying wheel is fixed on the multiplying wheel, multiplying wheel fixes by bearing and speedup wheel shaft, the speedup wheel shaft is fixed on the vehicle body 6 by connecting rod 5, and multiplying wheel links to each other with rear flywheel 8 by another chain 7, and rear flywheel is fixed on the hind axle.
With reference to Fig. 2, increasing another multiplying wheel 9 and the flywheel 10 that is fixed on another multiplying wheel between multiplying wheel and the rear flywheel, to increase the moving velocity of vehicle, another chain on the multiplying wheel links to each other with flywheel on another multiplying wheel, and another multiplying wheel links to each other with rear flywheel by the 3rd chain 11.
The utility model can be used for bicycle, three-wheel vehicle and four-wheeled.

Claims (2)
