Abstract
The utility model discloses a bicycle. The bicycle comprises a body and a double-chain driving mechanism, wherein the double-chain driving mechanism comprises a main chain disk, foot pedals and a rear flywheel; the main chain disk and the foot pedals are arranged on a middle shaft; the body is also provided with a secondary chain disk set; the secondary chain disk set comprises a driven chain disk and a driving chain disk which are arranged coaxially; a first chain is in socket connection between the main chain disk and the driven chain disk; a second chain is in socket connection between the driving chain disk and the rear flywheel; and the foot pedals drive the main chain disk to rotate and drive the bicycle to move forwards through the first chain, the driven chain disk, the driving chain disk, the second chain and the rear flywheel in turn. By adopting a two-stage transmission structure, the bicycle increases the transmission ratio of a driving wheel stage by stage and fulfils the aims of saving power and increasing speed; and the bicycle has the advantages of simple structure, easy improvement based on the conventional bicycle structure and low cost, and is convenient for use.
Description
Technical field
The utility model relates to a kind of bicycle.
Background technology
Existing standard bicycle generally adopts the transmission of strand bar, in order to reach laborsaving, and relatively to improve the purpose of road speed, the general mode that increases the chain drum number of teeth, reduces the flywheel number of teeth that adopts increases transmitting ratio, but, can only reach very limited speed-raising effect by the transmitting ratio that changes a pair of power wheel, maximum transmission ratio as ordinary bicycle is about 2.5, the maximum transmission ratio of 18 speed change racing cars is about 3.5, the bicycle of existing structure has limited the raising of the speed of a motor vehicle, can't reach laborsaving, high-revolving requirement.
The utility model content
At the problem that prior art exists, the purpose of this utility model is to provide a kind of structure through improving, to reach laborsaving, high-revolving bicycle.
For achieving the above object, the utility model bicycle, comprise vehicle body and double-stranded bar drive configuration, this two strands bar driver train comprises main chain dish and the pedal that is arranged on the axis, rear flywheel, also be provided with secondary chain drum group on the vehicle body, this pair chain drum group comprises the driven chain drum and the transmission chain drum of coaxial setting, wherein, be socketed with first chain between main chain dish and the driven chain drum, be socketed with second chain between transmission chain drum and the rear flywheel, drive pedal and drive the rotation of main chain dish, and successively by first chain, driven chain drum, the transmission chain drum, second chain, rear flywheel drives bicycle and moves ahead.
Further, the number of teeth of described main chain dish is more than the number of teeth of described driven chain drum, and the number of teeth of described transmission chain drum is more than the number of teeth of described rear flywheel.
Further, described transmission chain drum is the tight pulley structure, and it is fixedly installed on its transmission shaft.
Further, described transmission chain drum is the flywheel-type structure, and it is movably arranged on its transmission shaft.
The utility model increases the power wheel transmitting ratio step by step by adopting the two-stage drive mechanism, has reached purpose laborsaving, speed-raising, and it is simple in structure, be easy to improve on existing bicycle structure basis, has cost advantage low, easy to use.

Fig. 2 is double-stranded bar drive configuration scheme drawing;
Fig. 3 is the structural representation of secondary chain drum group;
Fig. 4 is the relative position structural representation of each power wheel in the double-stranded bar drive configuration.
The specific embodiment
As shown in Figures 1 to 4, the utility model bicycle, comprise vehicle body 1 and double-stranded bar drive configuration 2, the general frame structure of vehicle body 1 and the structure of existing bicycle are basic identical, double-stranded bar driver train 2 comprises the main chain dish 3 that is arranged on the axis and pedal 4, rear flywheel 5, also is provided with secondary chain drum group 6 on the vehicle body 1, and secondary chain drum group 6 comprises the driven chain drum 7 and the transmission chain drum 8 of coaxial setting, the number of teeth of main chain dish 3 is more than the number of teeth of driven chain drum 7, and the number of teeth of transmission chain drum 8 is more than the number of teeth of rear flywheel 5.Be socketed with first chain 9 between main chain dish 3 and the driven chain drum 7, be socketed with second chain 10 between transmission chain drum 8 and the rear flywheel 5, drive pedal 4 and drive 3 rotations of main chain dish, and drive bicycle and move ahead by first chain 9, driven chain drum 7, transmission chain drum 8, second chain 10, rear flywheel 5 successively.
In the utility model, transmission chain drum 7 can be the tight pulley structure, and it is fixedly installed on its transmission shaft, remains when bicycle returns chain by rear flywheel 5 chain back and forth, and promptly first chain 9 and second chain 10 all will turn round when returning chain.
The principle that the utility model utilizes the two-stage gear multiplication to quicken successively, adopt the structure of double-stranded dish, round trip flight wheel, effectively raise bicycle running speed, its transmitting ratio can reach about 7, the pedal that is the utility model bicycle turns around, almost being equivalent to the ordinary bicycle pedal changes 3 circles, and under identical moving velocity, it will be laborsaving greatly; Under identical application force, the speed of a motor vehicle will improve greatly, 20～25 kilometers/hour of general car scooters.
