The bicycle ensures the pedaling direction to be always tangent with the driving wheels when a user pedals, so that the power conversion efficiency is high, the riding is easier and the speed is faster compared with the exiting bicycle with the same gear ratio of the crankset and the flywheel.
Description
Technical field
The utility model relates to bicycle improvement technology.
Background technology
Existing bicycle all is to step on two foot-operated driving chain wheels rotations by the rider by pedaling, and rotates by chain wheel, chain drive flywheel and trailing wheel again.In foot-operated process of rotating a week, the strength of rider's pin is only had an appointment and 50% is converted to and drives the power that chain wheel rotates, thereby makes the existing cycling very effort of getting up, and speed also is difficult to further raising.
The utility model content
Technical problem to be solved in the utility model is to overcome the prior art deficiency, and a kind of bicycle light, that conversion efficiency is high that uses is provided.
For solving the problems of the technologies described above, the utility model is realized by the following technical solutions:
A kind of bicycle, comprise vehicle frame, front-wheel, trailing wheel and pedal actuating unit, described pedal actuating unit comprises the left side of equidirectional setting, right two flywheels foot-operated and that install with the trailing wheel concentric, with the chain wheel of flywheel by chain gear, a left side, the right two foot-operated left sides that are installed on respectively, right treadle one end, the two treadle other ends are movably installed on the hind axle, be fixed with two power wheels in chain wheel both sides and chain wheel by the unilateral bearing concentric, a left side, all be fixed with the driving force member tangent on right two treadles, on a left side with power wheel, be provided with between the right treadle and realize the two treadles movement transforming device of staggered action up and down.
As the improvement to such scheme, described Transmission is the arc-shaped rack that is fixed on the treadle, and the power wheel periphery is provided with and the arc-shaped rack ingear gear teeth, and the center of arc-shaped rack overlaps with rear axis.
Improve as the another kind to such scheme, described Transmission is a chain, and power wheel is a sprocket wheel, and chain is wound on the sprocket wheel.Described movement transforming device comprises that two ends are wound in the drag-line on two power wheels respectively, and the winding direction of drag-line on power wheel is opposite with the chain winding direction, is around on the pulley that is fixed on the vehicle frame in the middle of the drag-line.
Simultaneously, described movement transforming device can be: this device comprises the drag-line of two treadles about a connection, is around on the pulley that is fixed on the vehicle frame in the middle of the drag-line.
The utility model makes rider's step when action step direction always tangent with power wheel, the conversion efficiency height of power, and same chain wheel, flywheel teeth are lighter than riding under the situation, and speed is also faster.
Description of drawings
Accompanying drawing 1 is the utility model embodiment one structural representation;
Accompanying drawing 2 is a present embodiment pedal actuating unit structural representation;
Accompanying drawing 3 is the utility model embodiment two pedal actuating unit structural representations;
Accompanying drawing 4 is the utility model embodiment three pedal actuating unit structural representations.
The specific embodiment
For the ease of those skilled in the art's understanding, the utility model structural principle is further described in detail below in conjunction with specific embodiment and accompanying drawing:
Embodiment one: as shown in Figure 1.The bicycle that present embodiment discloses has advantages such as laborsaving, that speed is fast.This bicycle comprises vehicle frame 1, front-wheel, trailing wheel 2 and pedal actuating unit 3.Wherein, this pedal actuating unit 3 comprises the left side of equidirectional setting, the right side two foot-operated 31 and the flywheel of installing with trailing wheel 2 concentrics 32, with the chain wheel 34 of flywheel 32 by chain 33 transmissions, a left side, right two foot-operated 31 are installed on a left side respectively, right treadle 35 1 ends, two treadles, 35 other ends are movably installed on 2 of the trailing wheels, be fixed with two power wheels 36 in chain wheel 34 both sides and chain wheel 34 by the unilateral bearing concentric, a left side, all be fixed with the driving force member 37 tangent on right two treadles 35, on a left side with power wheel 36, be provided with between the right treadle 35 and realize two treadles 35 movement transforming device 38 of staggered action up and down.
When riding on the right of stepping on downwards, the transmission driving trailing wheel rotation that the right arc-shaped rack is tangential on the power wheel and drives power wheel, chain wheel and pass through chain, flywheel again, foot-operated on the right trampling to the lowest limit process, make on the foot-operated and left side treadle in the left side by movement transforming device and to put, the left side is foot-operated to be rocked to the extreme higher position and to be in and can to step under the state downwards thereby make.About two arc-shaped racks take turns up-and-down movement, drive power wheel and rotate, can realize the lasting output of power.
Embodiment two:
Again as shown in Figure 3.Present embodiment is compared with structure among the embodiment one, and its difference only is the difference of Transmission 37, movement transforming device 38, miscellaneous part all with embodiment one in identical.
Transmission is a chain in the present embodiment, power wheel is a sprocket wheel, chain is wound on the sprocket wheel, and this movement transforming device comprises that two ends are wound in the drag-line 381 on two power wheels respectively, the winding direction of drag-line on power wheel is opposite with the chain winding direction, is around on the pulley 382 that is fixed on the vehicle frame in the middle of the drag-line.
Because of similar among its principle of work and the embodiment one, do not give unnecessary details at this.
Embodiment three:
Again as shown in Figure 4.Present embodiment is compared with structure among the embodiment one, and its difference only is the difference of Transmission 37, movement transforming device 38, miscellaneous part all with embodiment one in identical.
