Abstract
A labour-saving variable-speed bicycle comprises wheels, a frame, a transmission mechanism and a pedal mechanism. The device is characterized in that the pedal mechanism adopts the lengthening pedal arm, and the pedal arms at the two sides make the axis of the pedal arms to be the center to swing repeatedly within the sector of 90 degrees; overrunning clutches are arranged between the pedal arms and between the axis of the pedal arms respectively, and the pedal arms at the two sides are mutual linkage by a leading rope which rounds the fixed pulley; a variable-speed device is arranged between the shaft of the pedal arms and the shaft of the disc chuck of the transmission mechanism. To be a rickshaw, the utility model changes the traditional circular motion into oscillating traverse motion, which lengthens the pedal arm as a force arm and presents a significant labor-saving effect, meanwhile, the utility model improves the speed of the rickshaw greatly under the cooperation with the variable-speed device for the labor-saving reason.
Description
Technical field:
The utility model relates to bicycle.
Background technology:
Bicycle is as walking-replacing tool or transportation means, and is closely bound up with people's daily life.Even the modern life that is showing improvement or progress day by day and following cyberage, the function of bicycle remains irreplaceable.
For a long time, the foot-operated mode of the bicycle be accustomed to of people is a circular movement.Because the moving radius of circular movement is restricted, therefore, circular movement has limited the improvement that bicycle can be made on laborsaving and raising speed.
Summary of the invention:
Technical problem to be solved in the utility model is avoided above-mentioned weak point of the prior art, and a kind of power saving speed changing bicycle is provided, and by changing foot-operated mode with laborsaving, and improves road speed.
The technical scheme that the utility model technical solution problem is adopted is:
The utility model comprises wheel, vehicle frame, transmission device and footstep mechanism.
Constructional feature of the present utility model is that described footstep mechanism adopts the lengthening treadle, the both sides treadle be with the treadle axle be the center, the fork of reciprocally swinging in the covering of the fans that are not more than 90 degree, be respectively arranged with overriding clutch between both sides treadle and treadle axle, the both sides treadle is each other by the drag rope interlock of walking around fixed pulley; Between the rotating shaft of described treadle rotating shaft and transmission device floral disc, change-speed box is set.
Compared with the prior art, of the present utility model producing effect is embodied in:
1, as rickshaw, the utility model will be ridden traditional circular movement and change into reciprocally swinging, and the length as the treadle of the arm of force is extended, and the labor-saving effect is remarkable, and can effectively improve the speed of a motor vehicle because of laborsaving.
2, in the utility model, the interlock form structure of both sides treadle is ingenious, can not bring the increase of energy consumption.
The drawing explanation:
Fig. 1 is the utility model structural representation.
Fig. 2 is another example structure scheme drawing of the utility model.
Fig. 3 is the utility model speed changer structure scheme drawing.
The specific embodiment:
Comprise wheel 1, vehicle frame 2, transmission device and footstep mechanism referring to accompanying drawing 1, present embodiment.
Footstep mechanism adopts lengthening treadle 3, and both sides treadle 3 is to be the fork at center with treadle axle 4, reciprocally swinging in the covering of the fans that are not more than 90 degree.Be respectively arranged with overriding clutch 5 between both sides treadle 3 and treadle axle 4, both sides treadle 3 is each other by drag rope 7 interlocks of walking around fixed pulley 6.
In order to improve the speed of a motor vehicle, adopt the mode that adds big speed ratio, can between the rotating shaft of treadle rotating shaft 4 and transmission floral disc 9, change-speed box 10 be set.In concrete the enforcement, shown in Figure 3, change-speed box 10 is two grades of speed changes of two-stage, by treadle axle 4, output shaft 13, the tween drive shaft 14 as input shaft; And be arranged between each and constitute intermeshing variable gear 15,16,17,18,19,12 and constitute, wherein, two gears 19,12 that are arranged on the output shaft 13 are dual gear that can slippage on it.
Two overriding clutch 5 usefulness keys are equipped in the two axial ends as the treadle axle 4 of input shaft, and the outer ring of overriding clutch 5 is fixedly installed on the rod end of treadle 3.
In addition, the power-transfer clutch 5 that is arranged in the change-speed box 10 adopts the serration power-transfer clutchs, and power-transfer clutch 5 is set in place on change-speed box 10, treadle axle 4 as input shaft.The clutch action of power-transfer clutch 12 can be used for conversion gear, reversing easily, adjusts, slides etc., and is extremely convenient.
Still adopt conventional sprocket wheel, chain gear between transmission floral disc 9 and the flywheel 11.
In order to guarantee treadle swing in suitable interval, shown in the figure,, postioning abutment 8 up and down is set respectively at the afterbody of change-speed box 10.
As shown in Figure 2, the utility model is equally applicable to cyclo.
Claims (3)
