Abstract
A kind of labour-saving new bicycle.It places the imput shaft outer end with the imput shaft certain position that raises with drive sprocket, and two step on handle uses semicircle ratchet sprocket piece instead and replace, and connects with left and right sides gear piece and conical gear between the two-wheeled sheet; Chain all is housed on the two-wheeled sheet, and pedal is equipped with in the chain lower end, and the chute of stablizing pedal is housed on the vehicle frame.Power arm is in the longest position all the time when scrunching, and the labor-saving effect is remarkable, with ordinary bicycle relatively, under the identical power of pedaling, moment increases and is twice.This car pedal return is stable, and shank does not have waste motion, and it is comfortable to ride.
Description
The present invention relates to a kind of new bicycle
In existing bicycle device, bicycle is stepped on handle and is made 360 deg garden Zhou Yundong, because foot-operated power is downward all the time, in last 180 degree of effectively work done, can produce the extremely short loss district of lower dead point and power arm, and loss in efficiency is very big.Also the someone proposes to step on handle with ratchet and improves, and steps on handle and does movement in a curve in imput shaft the place ahead, can reach certain labor-saving effect.But owing to step on handle and still do movement in a curve, the medium power arm of riding still has length to change, and can not be all the time puts forth effort in the strong point of power arm, still has partly loss in efficiency, and the labor-saving effect is satisfied inadequately.
The present invention promptly is design-calculated in order to overcome above-mentioned shortcoming.New model has solved steps on the shortcoming that handle is made the loss in efficiency that garden Zhou Yundong and movement in a curve produce, and foot-operated power is acted on to greatest extent advance and wasted power not.
New model is the imput shaft certain position that raises, and drive sprocket is placed the outer end of imput shaft, and two step on handle uses two halves garden sprocket piece instead and replace.Two halves garden sprocket piece is all installed forward, and an escapement is equipped with at its center respectively, and connects with imput shaft.One semicircle type garden awl gear piece (also available semicircle type fork sheet substitutes) respectively is housed in sprocket piece inboard, half garden, and two gardens awl gear piece is meshed with a return garden finishing bevel gear cuter (or return fork dish).Being fixed with two chains on the sprocket piece of two halves garden is meshed with sprocket wheel.The other end of chain connects with left and right sides pedal respectively, and the T sections is equipped with in the inner end of pedal, and places the chute of vehicle frame, treadles downwards, and chain promptly drives half garden sprocket piece rotation, drives imput shaft and rotates; Simultaneously by garden awl gear piece, the transmission of return garden finishing bevel gear cuter, second half garden sprocket piece promptly to the phase rear to rotation, and drive another chain, another pedal is risen.Because pedal chain is all the time vertically downward and tangent with half garden sprocket piece, very laborsaving so power arm is in the longest position all the time when scrunching, alternately depress pedal and can drive to advance.During coast, bipod can keep stable with stepping at present.
Compared with prior art, the present invention has the effect of bigger lowering and work-saving.Make the moving bicycle of the widely different transhipment of 360 deg and compare (all disregarding friction) with the common handle of stepping on, under the identical power of pedaling, moment increases and is twice.And the pedal return is stable, and shank does not have waste motion, and it is comfortable to ride.
Description of drawings of the present invention is as follows:
1. chute; 2.T sections; 3. pedal; 4. chain;
5. drive sprocket; 6. left half garden sprocket piece; 7. left return gear piece; 8. return garden finishing bevel gear cuter;
9. right return gear piece; 10. right half garden sprocket piece; 11. right escapement; 12. imput shaft;
13. left escapement.
Below in conjunction with accompanying drawing the present invention is further described:
Shown in figure one, imput shaft 12 positions of this car are higher than the axle center of front and back wheel, and chute 1. is housed on vehicle frame, and pedal 3. is made straight-line motion up and down in groove.The pedal upper end is connected with chain 4., and chain is meshed with half garden sprocket piece 6..Shown in figure two, the ratchet device 11., 13. of half garden sprocket piece and imput shaft 12. is connected, about return gear piece 7. is housed on the half garden sprocket piece, 9., return garden finishing bevel gear cuter 8. is equipped with at the center.Be the economy and convenience of making, left and right sides gear piece and all available fork dish of return garden finishing bevel gear cuter substitute.Drive sprocket 5. is fixed in the outermost end of imput shaft.
