Abstract
The utility model relates to a dual-speed bicycle which is provided with a two-teeth plate dual-speed rear sprocket wheel outside which two rows of teeth with different tooth numbers are sheathed so as to satisfy the different requirements of the young persons and the persons in middle and old age for the running speed of the bicycle when the young persons and the persons in middle and old age ride the bicycle. The young persons require the fast speed of the bicycle when riding the bicycle, a chain is engaged on the teeth plate with small number of teeth for the rear sprocket wheel, and the persons in middle and old age require the slow, light, labor-saving, safe and smooth speed of the bicycle when riding the bicycle, the chain is engaged on the teeth plate with a great number of teeth for the rear sprocket wheel. The dual-speed bicycle can be assembled with a chain shifter to become a speed changing bicycle, and the dual-speed bicycle is not assembled with the chain shifter to become a speed regulating bicycle.
Description
The utility model is two fast bicycles of a kind of adjustable speed, variable-ratio, belongs to the field of bicycle.
The history of existing centuries of bicycle.Bicycle is assembled by vehicle frame, handlebar, vehicle seat, wheel, pedal, chain drive, brake equipment, flywheel etc.At present, the kind of bicycle on the market, specification, model are a lot, and the single speed car is arranged, and derailleur is arranged.Derailleur has five speed, ten speed, ten two-speeds, 15 speed, 21 speed etc. multiple, but the productive costs height of these variable speed bicycles, and price is expensive, and all is by the racing car design-calculated, is characterized in the vehicle seat height, the car pad is hard and narrow, handlebar is low.The cyclist leans forward and bends over uncomfortablely, and the easy dirty trouser legs of no chain guard do not satisfy the needs that only need improve riding speed and not need the user of " graceful ", " fashionable ", and ordinary bicycle can not speed governing or speed change.The utility model is at above deficiency, designed assembling bidentate sheet flywheel on ordinary bicycle, makes bicycle become two fast bicycles of adjustable speed, refills to allocate the chain device and just become variable speed bicycle.
Accompanying drawing 1 is the bidentate sheet flywheel scheme drawing of the utility model two fast bicycles, (1)--inner blade, (2)--flywheel fuse, (3)--outer gear piece.When riding such as chain engages inner blade (1), bicycle speed is slow; During as the outer gear piece (3) of chain engages, the speed of a motor vehicle is just fast.Bidentate sheet flywheel and common monodentate sheet flywheel are except that the gear piece row number of Case of fly-wheel is different, and its structure, principle of work and processing are identical with common monodentate sheet flywheel.
The purpose of this utility model at ordinary bicycle can not speed governing deficiency and the vehicle seat height of racing car, the car pad is hard and narrow, handlebar is low.Deficiencies such as the easy dirty trouser legs of no chain guard satisfy young people, the elderly different requirements to the speed of a motor vehicle of ordinary bicycle.The young people requires the speed of a motor vehicle fast, and chain engages is on the outer gear piece (3) of flywheel, and is fast because of the few speed of a motor vehicle of the number of teeth when riding; When the elderly rode, chain engages was on the inner blade (1) of flywheel, and the speed of a motor vehicle is identical with ordinary bicycle during cycling.
The utility model has following advantage:
1. because bidentate sheet flywheel has been installed, make bicycle have two kinds of speed, satisfied young people, the elderly the different requirements of the speed of a motor vehicle voluntarily.
2. producing two fast bicycles increases costs seldom, only is the two toothrow sheets that the Case of fly-wheel produced has the number of teeth not wait.The bicycle price is low, and the customer can accept, and meets the national conditions of present China level of consumption.
3. speed governing is easy.Unclamp rear axle nut during adjustment, chain is transferred on the satisfied flywheel gear piece, fastening nut is just adjusted and is finished.Take turns to distance between rear shaft center owing to the gear piece adjustment of chain engages has changed chain,, can adjust chain apparatus or change the degree of tightness that chain is regulated in the position of rear axle rod on vehicle frame crab claw mouth because of in one centimeter.
4. the chain device is dialled in assembling at bidentate sheet flywheel place, just becomes variable speed bicycle.
5.24 " and during following two fast cyclings, with the few gear piece of the number of teeth, speed is fast, and is light laborsaving, safety and steady will more be subjected to young woman's favor.
6. production technology is easy, the general exchange of the spare and accessory parts except that flywheel, and Bicycle Plant can both produce, and those skilled in the art can both be by drawing assembling and debugging.
Claims (2)
1, two fast bicycles are assembled by vehicle frame, handlebar, vehicle seat, wheel, pedal, chain drive, brake equipment, bidentate sheet flywheel, and the flywheel that it is characterized in that this bicycle is a bidentate sheet flywheel, two toothrows that the Case of fly-wheel of flywheel has the number of teeth not wait.
2, bicycle according to claim 1 is characterized in that having assembled group variable speed bicycle that the chain device forms at bidentate sheet flywheel place.
