Abstract
The utility model relates to a bicycle, in particular to a dual-flywheel bicycle with two flywheels. The utility model comprises a faucet, a frame, a front wheel, a rear wheel, a first pedal transmission agent and a second pedal transmission agent. The first pedal transmission agent comprises a left pedal, a right pedal, a first transmission left crank shaft, a first transmission right crank shaft, a first transmission main shaft and bearing, a first drive chain wheel, a first driving chain, a first transmission flywheel and a flower drum cylinder which is also used in the second pedal transmission agent. The second pedal transmission agent which is concentric speed changing mechanism comprises a bracket, a main shaft, a bearing, a second drive chain wheel, a right transition chain wheel, a left transition chain wheel, a second transmission chain, a second transmission additional chain and a second transmission flywheel. The utility model has the advantages that the utility model dose not increase the length and the volume of the bicycle body and adds a driving force on the bicycle on the base of a common bicycle. The utility model can be used in long-distance company sport and the competition of riding tandem bicycles.
Description
Technical field
The utility model relates to bicycle, particularly the pattern dual instruction bicycle of taking turns with round trip flight.
Background technology
At present, existing bicycle if the band people rides can be difficult to ride, and double bicycle of riding is also arranged, but also exist volume longer, very unsafe shortcoming during turning.
Summary of the invention
The purpose of this utility model is to provide a kind of portable structure of riding simple, the concentric variable speed bicycle that can doublely ride.
The technical solution of the utility model is: a kind of pattern dual instruction bicycle comprises tap, vehicle frame, front and back wheel, the first foot-operated driving system, the second foot-operated driving system; The first foot-operated driving system and the second foot-operated driving system are installed in the left and right sides of vehicle frame respectively; The first foot-operated driving system comprises and turns axle, first transmission main shaft and bearing about left and right sides stretcher, first transmission, first initiatively chain wheel, first driving chain, the first transmission flywheel and with the second foot-operated shared Decorative drum of driving system; The second foot-operated driving system is exactly concentric speed-changing mechanism, and it comprises support, main shaft, bearing, second initiatively chain wheel, right transition chain wheel, left transition chain wheel, second driving chain, the additional chain of second transmission, the second transmission flywheel; Wherein the first transmission flywheel and the second transmission flywheel are contained in the left and right sides of Decorative drum respectively, and the main shaft both sides are provided with the pedal that turns axle; Decorative drum links to each other with steel ring by steel wire, and Decorative drum is fastened in the axis hole of vehicle frame by the block nut at two ends, and main shaft is installed in the endoporus of Decorative drum by bearing and adjustment steel bowl and tight locknut.
Advantage of the present utility model is: the utility model does not increase length over ends of body and volume on the ordinary bicycle basis, makes bicycle increase a propulsive effort, and the utility model can be used as long the match apart from go with motion and tandem bicycle and uses.
