Abstract
The utility model relates to a backward pedal bicycle characterized in utilizing a chain, which is a drive mechanism. The utility model comprises a frame, wheels, handlebars, a saddle and a driving mechanism, etc., wherein, a wheel body is fixed on the lower angle of the frame through a centre shaft, the chain drives a flywheel arranged on a back shaft. the improvement of the utility model is to extend a horizontal bracket supporting the back shaft on one side of the flywheel backward, the end part of the horizontal bracket is connected with a guide wheel, the chain is mounted between the chain wheel and the guide wheel, the lower part of the chain is in bridge connection with the upper part of the flywheel. Therefore, when the pedals are driven backward, the chain wheel and the guide wheel all rotate backward, but the flywheel realizes rotating forward under the drive of the lower part of the chain, then the bicycle is moved forward. The drive mechanism of the utility model is the simplest in structure and does not reduce the mechanical efficiency, thereby being a bicycle with least resistance.
Description
The utility model relates to a kind of driving device to use the bicycle of chain as characteristics, specifically a kind of pedal-type bicycle backward.
Generally be to pedal forward to ride to overtake by bike, because people's pin is the stage that work done is exerted oneself pedaling forward and downwards when riding from the top dead point of pedal.At this moment, the application of force direction of leg forward, reactive loss is bigger, thus relatively the effort.If scrunch the mode that bicycle is moved ahead backward and change into, then pedal and ride the human posture that force mechanism is similar to block clearance time this moment, therefore more suitable human muscular tissue structure, and the angle of application of force direction and bicycle crank makes applied moment reach maximum near 90 degree.Thereby after pedal before the line bicycle use more laborsaving than standard bicycle.The CN00234720 patent disclosure a kind of reversely riding bicycle, the actuating device of this car is to drive driving gear by crank shaft, driving gear drives driven gear, driving gear and driven tooth crop rotation backward rotation, driven gear drives wheel disc through driven shaft, wheel disc drives chain, and chain drives the flywheel on the hind axle again, to realize car to overtake.This bicycle is because of having installed the set of gears transmission device again additional on the basis of original transmission device, so structure is comparatively complicated.And two sets of transmission mechanism combine, mechanical efficiency must decrease, after pedal labour-saving effect thereby not fairly obvious.
The purpose of this utility model just provides a kind of pedal-type bicycle backward simple in structure, easy to use, for bicycle family increases a newcomer.
The utility model is achieved in that originally pedal-type bicycle still includes vehicle frame, wheel, handlebar, vehicle seat and transmission device etc. backward, at the vehicle frame inferior horn by the fixing wheel disc of axis, chain drives the flywheel that is installed on the rear axle, institute's improvements are that the transverse bracket that will support rear axle in flywheel one side extends back, its end connects track adjusting wheel, chain is socketed between wheel disc and the track adjusting wheel, and the chain bottom is connected across flywheel top.Like this, when kicking backward tap pedal, wheel disc and track adjusting wheel all rotate backward, but flywheel has then been realized rotation forward under the proal drive of bottom chain, drive bicycle thus and move ahead.
The utility model has just installed a track adjusting wheel additional dexterously, still utilizes original chain drive on the bicycle, can realize pedaling the purpose that moves ahead behind the bicycle.Not only the structure of actuating device has reached the simplest, and mechanical efficiency do not have anything to reduce yet, and therefore is a kind of bicycle in labour-saving the most.With this mode stock car, can make athletic achievement have one significantly to break through and improve.For frequent long-distance people by bike, also can save the muscle power more than at least 20%.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a local structure scheme drawing of the present utility model.
As shown in Figure 1, by the fixing wheel disc 7 of axis, flywheel 4 is installed on the rear axle at vehicle frame 9 inferior horns, and the transverse bracket 5 that is fixedly connected with vehicle frame 9 is supported on the two ends of rear axle.Transverse bracket 5 in flywheel one side extends one section backward, the track adjusting wheel of portion's support and connection in its back-end 3, and chain 6 lengthenings, and be socketed between wheel disc 7 and the track adjusting wheel 3, the chain bottom is connected across flywheel 4 tops.The tap pedal 8 of kicking backward, row behind chain 6 tops, the bottom moves ahead, thereby drives flywheel 4 forward rotation forward, and bicycle is moved ahead.Be firm support track adjusting wheel 3, can between the oblique fulcrum bar 11 at the axle center of track adjusting wheel 3 and vehicle frame or vehicle frame rear portion, be connected with pole.This vehicle is suitable as sport-racing car.
As civilian bicycle, have back clothes hanger 10 more, back clothes hanger pole 1 is supported between rear axle and the back clothes hanger.So just can between the axle center of track adjusting wheel 3 and back clothes hanger 10, connect a perpendicular pole 2, with transverse bracket 5 firm support track adjusting wheels 3.
Claims (2)
1, a kind of pedal-type bicycle backward, include vehicle frame, wheel, handlebar, vehicle seat and transmission device, at vehicle frame (9) inferior horn by the fixing wheel disc (7) of axis, chain (6) drives the flywheel (4) that is installed on the rear axle, it is characterized in that the transverse bracket (5) that supports rear axle in flywheel one side extends back, its end connects track adjusting wheel (3), and chain (6) is socketed between wheel disc (7) and the track adjusting wheel (3), and the chain bottom is connected across flywheel (4) top.
2, pedal-type bicycle backward according to claim 1 is characterized in that being connected with pole between the axle center of track adjusting wheel (3) and vehicle frame.
