Abstract
The utility model relates to a rotary two-speed body-building bicycle, belonging to the field of vehicles. The rotary two-speed body-building bicycle is provided with a basic structure of the common bicycle. The rotary two-speed body-building bicycle is characterized in that The rotary two-speed body-building bicycle is also provided with a large flywheel (9) and a guide wheel (8). The large flywheel (9) and a small flywheel (10) are together fixed on a shaft hub on the same side of a rear wheel (11). The guide wheel (8) is fixed on a rear pull bicycle of a bicycle frame (1). The rotary two-speed body-building bicycle has the advantages that the rotary two-speed body-building bicycle is forwards and rearwards pedaled, the rotary two-speed body-building bicycle can forwards run, and the rotary two-speed body-building bicycle can be optionally transformed at any time. The rotary two-speed body-building bicycle not only can be used as a riding tool, but also has the functions of body-building and recreation.
Description
The utility model belongs to field of vehicles, relates to a kind of swinging double speed body-building bicycle.
In the prior art, bicycle, kind is a lot of in appearance and modeling and speed transformation, but its common ground all is to scrunch forward, and car is moved ahead, and when scrunching backward, it is invalid that car is moved ahead, the wheel that just falls slides, and also may fall chain sometimes.Except that child's bicycle, substantially all as people's walking-replacing tool.
The purpose of this utility model provides a kind of swinging double speed body-building bicycle, both can make walking-replacing tool, has special body-building function again, both can scrunch forward, can scrunch backward again, can fit feelings conversion easily at any time, all can advance forward, especially be fit to the elderly's double body-building of riding.
Concrete scheme is as follows:
Basic structure with ordinary bicycle: vehicle frame 1, vehicle seat 2, handlebar 3, front-wheel 4, pedal 5, wheel disc 6, chain 7, small flywheel 10, trailing wheel 11 is characterized in that: also have big flywheel 9, guide wheel 8; Big flywheel 10 is fixed on the axle skin of trailing wheel 11 the same sides jointly with small flywheel 10, " very heavy " in " very heavy " in it and the small flywheel 10 in the same way; Guide wheel 8 be fixed on vehicle frame 1 after pull a cart on; Chain 7 is from wheel disc 6, successively the big flywheel 9 of pile warp, guide wheel 8, small flywheel 10, the wheel disc 6 that unrolls again.
Operation logic: when scrunching pedal 5 forward, wheel disc 6 clickwises, and under chain 7 effects, drive big flywheel 9 clickwises, its " very heavy " works and affects trailing wheel 11, and car is moved ahead, drive guide wheel 8 clickwises, small flywheel 10 left-hand revolutions simultaneously, because of " very heavy " in its " very heavy " and the big flywheel 9 in the same way, so the time 10 of small flywheels fall wheeled slip, it is invalid that car is moved ahead; When kicking backward tap pedal 5, wheel disc 6 left-hand revolutions, and under chain 7 effects, drive big flywheel 9 left-hand revolutions, but this moment, it fell wheeled slip, it is invalid that car is moved ahead, drive guide wheel 8 left-hand revolutions, small flywheel 10 clickwises simultaneously, this moment, " very heavy " of small flywheel 10 worked, and affected trailing wheel 11, and car is moved ahead; So, no matter scrunching pedal 5 forward or backward, Che Junneng moves ahead, and chain 7 has one section to be in the tensioning shape all the time, difficultly falls chain.During garage advances, do not scrunch pedal 5, as ordinary bicycle, can fall automatically " very heavy " slide forward.Small flywheel 10, big flywheel 9, wheel disc 6, guide wheel 8, its number of teeth and middle footpath can be mated as required.
Usefulness of the present utility model is, a kind of swinging double speed body-building bicycle is provided, and both can make walking-replacing tool, has special body-building recreation function again; Scrunch forward with backward, can fit feelings conversion easily at any time, all can advance forward; Scrunch forward when driving a vehicle against the wind, going up a slope scrunches when advancing backward, all free and relaxed than ordinary bicycle, is particularly suitable for that the elderly rides, body-building and amusement.
Accompanying drawing 1, structural representation is always schemed;
Embodiment: further describe in conjunction with the accompanying drawings
Big flywheel 9 outside, small flywheel 10 is interior, and the two is fixed on the axle skin in trailing wheel 11 outsides with the dextrorotation screw thread jointly, and when scrunching pedal 5 forward, " very heavy " in the big flywheel 9 work, and affect trailing wheel 11, and car is moved ahead; When kicking backward tap pedal 5, " very heavy " in the small flywheel 10 works, and affects trailing wheel 11, and car is moved ahead; Chain 7 is commercially available common chain, do to add long process, about the gear teeth supporting with it; Guide wheel 8 by suspension clamp plate 12 be fixed on vehicle frame 1 after pull a cart on.
Small flywheel 10 numbers of teeth are a, and middle footpath is b, and the number of teeth of big flywheel 9 and middle footpath should be 1.6～2.0 times of small flywheel 10 mutually; The number of teeth of wheel disc 6 and middle footpath should be 1.8～2.6 times of small flywheel 10 mutually; The number of teeth of guide wheel 8 and middle footpath are suitable with small flywheel 10.
