Problems solved by technology

[0004] Bicycle belongs to a kind of simple walking-replacing machine, and through hundreds of years of development, although the technology is very mature and stable, it is difficult to make a major breakthrough in technology, but the bicycles currently available in the market have the following disadvantages: 1) mostly adopt pedal circle The driving mode is equivalent to a person doing long-span running. The exercise is intense, the muscles are highly contracted, the energy consumption is huge, and people are easily fatigued.
2) The pedal handle is short and the effective moment arm is short
3) Due to the circular motion of the pedals, the effective force arm changes cyclically from: zero---maximum---zero---(counting from the pedals bei...

Embodiment 1

[0074] Such as figure 1 Shown is a reciprocating pedaling driving device 500 of a reciprocating pedaling type power-assisted bicycle, which includes a driving rear wheel 510 and a rear wheel shaft 520, and the driving rear wheel 510 has the same rim 430 and tire 400 as the front wheel. The left and right sides of the frame 100 are respectively provided with a pedal handle 540 (only one of them is shown), a pedal 541 fixed on the pedal handle 540 and a sector-shaped active meshing wheel 542 of an internal ring gear structure, which is connected with the sector-shaped active engagement wheel. The one-way flywheel 543 with meshing teeth meshed with the meshing wheel 542, and the pedal 541 is fixed on the front end of the pedal handle 540, and the fan-shaped active meshing wheel 542 is fixed on the 540 rear end of the pedal handle, between the two ends of the pedal handle 540 There is a pin hole on the handle body between them, and a handle pin 544 is connected to the frame 100, a...

Embodiment 2

[0077] Such as figure 2 , 3 , shown as a two-stage series-connected gear-type pedaling one-way driver of the reciprocating pedaling drive device 500, which includes a one-way driving driving roller 521 directly fixed to the center of the rear wheel 510, and the left and right ends of the driving roller 521 A wheel shaft sleeve 5210 is fixedly connected to the top, and a rolling bearing 522 is arranged between the wheel shaft sleeve 5210 and the rear wheel shaft 520. A brake disc 524 is fixedly connected to one side of the driving roller 521; Gear 5211; left and right two one-way flywheels 543 include outer ring gear 5435 and traditional one-way ratchet mechanism-comprising ratchet ring 5432 on the outer ring surface of one-way flywheel 543 and one-way flywheel 543 The elastic ratchets 5431 on the inner ring 5430 are respectively movably matched with the inner ring 5430 on the hub 5210 on the same side. In addition, the one-way flywheels 543 on both sides are provided with th...

Embodiment 3

[0081] Such as Figure 4, shown as a two-stage series-connected sprocket type pedaling unidirectional driver of the reciprocating pedaling drive device 500, since the sector-shaped active meshing wheel 542 can also be an inner arc chain segment structure (not shown in detail), therefore, with the inner arc chain segment The one-way flywheel 543 of the sprocket outer ring type and the pedal one-way driver are engaged with the meshing wheel 542, which includes a one-way drive driving roller 521 directly affixed to the center of the rear wheel 510. The driving roller 521 has two left and right sides. A wheel shaft sleeve 5210 is fixedly connected to the end, a rolling bearing 522 is arranged between the wheel shaft sleeve 5210 and the rear wheel shaft 520, and a brake disc 524 is fixedly connected to one side of the driving roller 521; Ratchet gear 5211; left and right two one-way flywheels 543 include outer ring sprocket 5435' and traditional one-way ratchet mechanism-comprising...

Abstract

This invention is about a repeated pedaling assistant bicycle. It includes the frame, the braking mechanism, the back driving wheel, the back wheel bearing, the tyres, the pedals which is fastened to the pedaling handles, the fan-like forward meshing wheel which meshes the gearing one-way flywheels. On each side of the frame, there a pedaling handle and pedals, the fan-like forward meshing wheel and the one-way flywheel among which the pedal is fixed on the front of the handle and the fan-like forward meshing wheel on the back, in the part between them are some pinning holes, in the frame are some handle pins. Through the pinning holes and the pins, the handles can be knuckled on the frame. The fan-like forward meshing wheel is structured with inward gearing hoops or roller chain section of intrados, the outside circle of the one-way flywheel are gear wheel or chain wheel, the pedaling handles are jointed with the top surface or the outside circle surface of the fan-like forward meshing wheel, and on the edge of the pedals are some edge hooks. This invention is simple and feasible with a light structure, and it works efficiently and rides comfortably with a character of anti-shocking and anti-tire-bursting.

Description

【Technical field】 [0001] The present invention relates to a pedal bicycle, and more particularly, the present invention relates to a reciprocating pedal bicycle. 【Background technique】 [0002] Bicycles are widely adopted by families and individuals in China because of their economy, convenience, flexibility, pollution-free, and free parking. Although with the improvement of people's lives, mainstream means of transportation and machinery are constantly being upgraded: from bicycles to buses, from buses to motorcycles, and then from motorcycles to private cars... This development trend is in the ascendant, but with it The social, natural, and economic problems such as energy shortage, environmental pollution, and traffic congestion that come with it are also becoming a strong resistance to restricting this development trend. It can be predicted that in the next few decades, no matter in China's urban or rural areas, the vast majority of the population will still use bicycle...
