Description

The bicycle that high-speed booster is arranged

The utility model relates to bicycle, refers in particular to the speeding-up bike that a kind of speed of a motor vehicle can be accelerated.

Existing bicycle adopts so-called " accelerating axle " to improve road speed, but in the modern metropolitan cities life that general rhythm of life is accelerated, its speed of a motor vehicle has not satisfied people's requirement, particularly often taking place in some cities of traffic jam, the more selection of people is on and off duty by bike, maneuverability, freely make things convenient for, if bicycle is improved the way of speed from present employing " accelerate axle ", further improve bicycle speed, then use the people of bicycle can be more.

The purpose of this utility model just provides a kind of bicycle that high-speed booster can be arranged in order to further raising bicycle speed.

The purpose of this utility model is achieved in that the bicycle of high-speed booster, it comprises wheel, vehicle frame, transmission device and boost installation, it is characterized in that: boost installation contains hinge wheel, change wheel, linkage drive shaft mechanism, drives bracing strut and connects connecting element, drive bracing strut and be fixedly mounted on the cycle frame, the two ends that are installed on the linkage drive shaft mechanism of driving on the bracing strut are established hinge wheel and change wheel respectively; Hinge wheel is provided with the driving chain that is connected with the rear wheel flywheel and establishes guide wheel; Change wheel by with bicycle chainwheel ingear driving chain and sprocket wheel mutually transmission link and also can establish guide wheel.

Above-mentioned design, because hinge wheel, change wheel are to be packed on the same axostylus axostyle of linkage drive shaft mechanism or the axle sleeve, so the steamboat that drives an end when the pedal bicycle chainwheel is a change wheel when rotating, other holds hinge wheel just to rotate, hinge wheel is flying wheel behind the driving bicycle again, obviously reached the effect of the multistage multiplication of speed, will can increase by 2～4 times than the present bicycle speed of a motor vehicle according to measuring and calculating, and laborsaving.

Below by accompanying drawing and enforcement the utility model is described further again.
