Abstract

The utility model relates to a high speed bicycle which is composed of wheels, a frame, a handle, pedals, chains, a toothed disk and a flywheel. The utility model is characterized in that the chain wheel driving mechanism is provided with two or three chains; a middle speed change wheel is arranged the toothed disk and the flywheel; the toothed disk drives the speed change wheel by chains; the speed change wheel drives the flywheel by chains. The utility model has the advantages of the ordinary bicycle with handiness, maneuver, facility, etc., replaces the common vehicles at higher speed, reduces vehicle noise and environmental pollution of tail gas, and relieves energy crisis.

Description

High-speed bicycle

The utility model belongs to the improvement of bicycle, mainly is the improvement to its speed.

From Feng's Grice baron invention wooden horse formula bicycle, load onto chain to the Frenchman, the German loads onto the car flying kick and steps on and advance, and is modern bicycle to British Deng Luopu invention tyre setting.The development of bicycle over more than 100 year, is continued to use traditional strand type of drive always.In the world, the development of bicycle just is in continuous innovation and the evolution from its birth the time always, mountain bike is the rising star of modern bicycle development, can be by gear shift, the speed of regulation and control bicycle, international bicycle racing also is this type car.In addition, multi-form in addition abroad, ride treadmill such as double or many people, the bicycle of band shell, folding bicycle or the like is made a general survey of its class, is strand formula bicycle entirely, have in addition do not have a chain.At home, bicycle trade is produced approved product basically or is introduced mountain bike outside the producing country, and Shang Weijian has other innovations to occur.Generally per hour below 15 kilometers, this mainly is because its transmitting ratio is less to the riding speed of existing bicycle, realizes that on the little bicycle in locus bigger transmitting ratio has certain difficulty.

The purpose of this utility model is to provide a kind of high-speed bicycle, does the people under the situation of same merit, can obtain at double or be several times as much as the speed of existing bicycle, to substitute general self-propelled vehicle, reduces environmental pollutions such as noise, tail gas, alleviating energy crisis.

The technical solution of the utility model is: a kind of high-speed bicycle, it has wheel, vehicle frame, handrail, foot-operated, chain, chain wheel, flywheel, it is characterized in that in its chain wheel driving mechanism 2-3 bar chain being arranged, change wheel in the middle of being provided with between chain wheel and the flywheel, chain wheel drives change wheel by chain, and change wheel drives flywheel by chain.

As above-mentioned high-speed bicycle, it is characterized in that change wheel is installed in respectively on the coaxial axis of flywheel shaft, chain wheel axle.

The sprocket transmission device of high-speed bicycle of the present utility model is a kind of device that is formed by chain wheel, chain, change wheel and flywheel, is connected by chain between chain wheel, change wheel and the flywheel.Axis and rear axle that this device should suitably increase bicycle are installed, and vehicle frame is to the trailing wheel support section, must be through expanding to the degree that is fit to install acceleration device, keep car to fly simultaneously and chain wheel between the elasticity of chain, when transmission, do not produce friction, till going slick.Fast 1.2 times of double-stranded bicycle speeds than standard bicycle, fast about 1 times than mountain bike.Three chain types then are 3.6-3.8 times of standard bicycle, more than 3 times of mountain bike.Ride per hour 15km (flying the 20-22 tooth, dish 44-48 tooth) of standard bicycle, then do same merit, the speed car per hour is about 80 kilometers, not second to the general power actuated vehicle speed of a motor vehicle.

Fig. 1 is embodiment 1 structural representation of the present utility model.Wherein, 1 chain wheel, 2 chains, 3 flywheels, 4 change wheels.

Fig. 2 is the structural representation of the utility model embodiment 2.

Fig. 3 is the sprocket transmission device structural representation among Fig. 2.Wherein, 2-1,2-2,2-3 are chains, 4-1,4-2 are change wheels.

Structure of the present utility model as shown in Figure 1, it has wheel, vehicle frame, handrail, foot-operated, chain, chain wheel, flywheel, its feature is in its chain wheel driving mechanism, have additional change wheel 4, change wheel 4 is installed between chain wheel and the flywheel, chain wheel drives change wheel 4 by chain 2, and change wheel 4 drives flywheel 3 by chain, because the effect of change wheel 4 can obtain bigger transmitting ratio.

Fig. 2 is the structural representation of another embodiment of the present utility model.This embodiment has two change wheels, change wheel 4-1 and flywheel 3 are contained on the same axis, change wheel 4-2 and chain wheel 1 are contained on the same axis, chain 2-1 connects chain wheel 1 and change wheel 4-1, chain 2-2 connects change wheel 4-1 and change wheel 4-2, chain 2-3 connects change wheel 4-2 and flywheel 3, has 2 change wheels, 3 chains, thereby bigger converter speed ratio is arranged.The change wheel of this scheme and chain are positioned at the position of standard bicycle, and easier use habit with people is coincide.

Full-scale investigation of the present utility model.Experiment is to carry out two chain types and the split type installation of three chain types is carried out on same bicycle, and two chain types adhere to specification fully, and the experiment of riding is succeedd, in three chain types when idle running, is just like designing requirement, manufacturing conditions is limit, and produces friction when riding, so the effort point that seems of riding.Generally speaking, experiment has confirmed the science of invention fully, and reasonableness and huge economic technology are worth and the social development prospect.Certainly, ride high-speed bicycle than riding ordinary bicycle and can feel to draw the power paid more greatly, when especially beginning to start.But be to ride instead of walk at a distance fully, people can bear.If three chain types experiment installation portion potential energy carries out at bicycle dress chain place, its stability etc. are finished design idea and requirement fully when better, easily reach high-speed.

It is portable and smart that the utility model does not change ordinary bicycle, the inherent characteristicses such as maneuverability. Have widely practical future, can ride instead of walk at home, It is cross-country to revolve trip, long-distance short distance all can, accelerate rhythm of life, civilian, military, national defence, fast reaction. It is the novel traffic that a kind of science is suitable for Instrument.
