Abstract
The utility model discloses a double-chain bicycle, which can not change an integral structure of a bicycle; only a left chain disk is added on the left part of a middle shaft of an existing bicycle; a left flywheel is added on the left part of a back shaft of the bicycle; a left chain is sheathed on the left chain disk and the left flywheel, forming a transmission chain. When the bicycle runs, the utility model can overcome the consumption of idle work because of double chain transmission, the utility model has labour saving, and the bicycle speed is quick; because the stress of the middle shaft and the back shaft is balanced, the shaft sleeve is difficult to damage, and the service life of the bicycle is extended; the utility model is an ideal tool instead of waling.
Description
The utility model relates to a kind of double-stranded bicycle, belongs to bicycle drive technology field.
The chain gear of all keeping right of existing bicycle, racing car, in the time of by bike, when left foot after, right crus of diaphragm is when preceding pedaling because the right crus of diaphragm stirrup is nearer from chain drum, power arm is shorter, the right crus of diaphragm effort; When right crus of diaphragm after, left foot is when preceding pedaling because the left foot stirrup is far away from chain drum, power arm is longer, left foot is more laborsaving.This shows, cyclist's both feet comparatively speaking, left foot is laborsaving than right crus of diaphragm, if for a long time by bike, because both feet are firmly uneven, very easily produces tiredly, and the drive disk assemblies such as flywheel of bicycle are also very easily damaged, cause the lost of life of bicycle.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art and a kind of left chain drum that installs additional on the axis of bicycle is provided, and installs left flywheel on the rear axle additional, reduces fatigue in the time of by bike, improves the speed of a motor vehicle, prolongs the bicycle double-stranded bicycle in service life.
The purpose of this utility model is achieved in that it comprises bicycle integral body, and its structural feature is that the left part at bicycle middle shaft is equipped with left chain drum, and the left part of rear axle is equipped with left flywheel, and left chain drum is connected by chain with left flywheel.
The purpose of this utility model can also realize by following technical measures: left chain drum is identical with right chain drum specifications and models, and left flywheel is identical with right flywheel specifications and models.
Compared to existing technology, the utlity model has following advantage:
1, laborsaving by bike: owing to added left chain drum and left flywheel, in making, the rear axle stress balance, the laborsaving indefatigability of cyclist.
2, faster than the strand dish bicycle speed of a motor vehicle; Left and right sides pin is firmly even, two chain sprocket drive, and then accelerated the speed of a motor vehicle.
3, long service life, the rear axle of strand dish bicycle are because of the both sides unbalance stress, and the right side members of rear axle is very easily damaged and caused the distortion of hind axle skin, and double-stranded dish of the present utility model solves these problems, thereby has prolonged the service life of bicycle.
4, be used for racing car, can greatly improve racing car speed, improve games results.
Embodiment describes the utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is an integral structure scheme drawing of the present utility model.
Fig. 2 is the birds-eye view of Fig. 1.
Among the figure, handlebar (1), vehicle seat (2), front-wheel (3), right crus of diaphragm stirrup (4), right chain drum (5), right chain (6), right flywheel (7), axis (8), left foot stirrup (9), left chain drum (10), left chain (11), rear axle (12), left flywheel (13), trailing wheel (14).
The utility model is the improvement to existing bicycle running part, and its design philosophy is not change the bicycle integral structure and only install left chain drum additional on the axis of existing bicycle, on rear axle, install left flywheel additional, in order to overcome the consumption of idle work, improve the speed of a motor vehicle, reduce cyclist's fatigue.According to this design philosophy, the utility model such as Fig. 1 are shown in Figure 2, at the left part of the axis (8) of bicycle one left chain drum (10) are installed, and left chain drum (10) is identical with right chain drum (5) structure and specification model, and installation method is also identical.At the left part of bicycle rear axle (12) a left flywheel (13) is installed, left side flywheel (13) is identical with right flywheel (7) structure and specification model, installation method is also identical, left side chain drum (10) links together with left chain (11) with left flywheel (13), constitute messenger chain, left chain (11) and be sleeved on left chain drum (10) and the left flywheel (13), left chain drum (10), left flywheel (13) can be installed on the instrument of riding instead of walk such as bicycle racing too.
In the time of by bike, the people is seated on the vehicle seat (2), walking vehicle handle (1), both feet are set foot on pin stirrup (4), (9), chain (6) (11) and are turned round along with the action of pin stirrup (4) (9), driving bicycle wheels (3), (14) travel forward, and under the effect of two strands, it is not only laborsaving but also comfortable to travel by bike.
Claims (2)
1, a kind of double-stranded bicycle, it comprises bicycle integral body, it is characterized in that the left part of bicycle middle shaft is equipped with left chain drum, and the left part of rear axle is equipped with left flywheel, and left chain drum is connected by chain with left flywheel.
2, double-stranded bicycle according to claim 1 is characterized in that left chain drum is identical with right chain drum specifications and models, and left flywheel is identical with right flywheel specifications and models.
