Abstract
The invention discloses a novel driving device of a bicycle. The bicycle mainly comprises a bicycle frame (1), a gearbox (13), a driving rear wheel (11), an overrun clutch (37) and the driving device mounted on the bicycle frame (1) and the gearbox (13). The driving device is characterized by mainly comprising pedals (2), pedal driving arms (4) and pedal balance reset tension springs (6). According to the invention, a pedal driving device driving system is independently arranged, so that the defects that a driving connecting rod of a bicycle with the Chinese patent number of 201420590209.3 in the prior art adopts a single-side single-bar structure and is unilaterally stressed when being pulled to cause non-uniformity of overrun clutch stress, high possibility of breakage and low durability and the like are overcome; therefore, the novel driving device of the bicycle is uniform in overrun clutch stress, quite durable, and quite convenient and stable to tread, and cannot be broken.
Description
Technical field
The invention belongs to bicycle driver, particularly relate to a kind of user can be allowed to step on up and down in the mode of standing pedal drive car body advances, the gravity of namely employment self makes a kind of driving device for bicycle of the wheel turns of underfooting.
Background technology
Self traditional power ride instead of walk preferably and the instrument of practicality is bicycle: be widely used in the world, and the actuating device of bicycle is the part and parcel in bicycle, the actuating device of common bicycle takes disk to drive chain sprocket structure, make circumferential running by two pin to drive the wheel turns be connected with flywheel to move ahead, can move in a circle buttocks must be erected for making two pin, health is in abnormal, is not easy to firmly.Also have the large of a kind of similar Kickboard Scooter to obtain power mainly with a feet step on the ground, the Kickboard Scooter that this tradition obtains power not only consumes one's strength, also needs special skill, and requires great effort very much, is therefore not suitable for ordinary people and uses.In prior art, China Patent No. 201210084957.X is a kind of from sport car.This kind is be made up of gearbox from the car body of sport car, and on gearbox, pedal-type driving mechanism is housed.Its pedal-type driving mechanism mainly comprises actuating arm, stretcher and Flexible Reset device, the two ends of this axle drive shaft are respectively connected with the front end of one or two actuating arm, be equipped with stretcher at the rear portion of the actuating arm at two ends, Flexible Reset device is housed between actuating arm and gearbox.Although also should be a kind of driving device for bicycle that a kind of gravity with mode employment self of standing makes the wheel turns of underfooting from the power of the advance of sport car, but this kind of pedal-type driving mechanism adopts stretcher directly to drive actuating arm to drive, again by the axle drive shaft on actuating arm Direct driver gearbox, rotate to drive drive wheel finally by the output shaft be located on two gearboxes in left and right, therefore this automatic carrier drives not light, ride and require great effort a little, and it is not very steady, again owing to rotating to drive drive wheel finally by the output shaft be located on two gearboxes in left and right, therefore in the middle of travelling, run into the distortion that road injustice will cause output shaft, make one of them wheel cannot with earth surface, thus both feet center of gravity of people when treadling can be caused to swing, very unstable, foot-operated from running also danger close, entail dangers to personal safety, even likely can cause the distortion of output shaft, gearbox just cannot work, and the foot-operated function from running cannot be realized.
Summary of the invention
The object of the invention is for bicycle in prior art and the shortcoming from sport car existence, a kind of user is provided to step on a kind of driving device for bicycle of pedal driving vehicle advance in the mode of standing, drive not light to solve automatic carrier in prior art, ride and require great effort a little, the distortion that road injustice will cause output shaft is run in the middle of travelling, make one of them wheel cannot with earth surface, both feet center of gravity of people when treadling can swing very unstable, even likely can cause the distortion of output shaft, the problems such as gearbox just cannot work.
Technical scheme of the present invention is: a kind of driving device for bicycle, mainly comprise vehicle frame 1, change speed gear box 13, be arranged on the driving trailing wheel 11 on output shaft of gear-box 10, the actuating device being arranged on the overriding clutch 37 on transmission input shaft 9 and being arranged on vehicle frame 1 and change speed gear box 13, it is characterized in that: described actuating device is primarily of stretcher 2, footboard drives arm 4 and stretcher balance reset tension spring 6 form, structure between it and installation connection are: stretcher 2 is mounted on the front end of footboard drives arm 4, a mounting hole 17 is provided with in the rear end of footboard drives arm 4, footboard drives arm 4 rear end is fixedly connected on the transmission input shaft 9 outside change speed gear box 13 by mounting hole 17,
Described stretcher balance reset tension spring 6 has three kinds of mounting connection structures: the first mounting connection structure is: stretcher balance reset tension spring 6 one end sockets on vehicle frame 1, the other end sockets at the middle part of footboard drives arm 4, and footboard drives arm 4 is now arranged to the shape bent; The second mounting connection structure is: stretcher balance reset tension spring 6 one end sockets on vehicle frame 1, the other end stretcher socketed in footboard drives arm 4 front end is flexibly connected on axle 14; The third mounting connection structure is: stretcher balance reset tension spring 6 one end sockets on vehicle frame 1, the other end sockets on actuating arm journal stirrup 18 attaching parts of the rear end of footboard drives arm 4.
A kind of driving device for bicycle of the present invention compared with prior art has the following advantages: because described actuating device is primarily of stretcher 2, footboard drives arm 4 and stretcher balance reset tension spring 6 form, structure between it and installation connection are: stretcher 2 is mounted on the front end of footboard drives arm 4, a mounting hole 17 is provided with in the rear end of footboard drives arm 4, footboard drives arm 4 rear end is fixedly connected on the transmission input shaft 9 outside change speed gear box 13 by mounting hole 17, stretcher balance reset tension spring 6 sockets between footboard drives arm 4 and vehicle frame 1, and be provided with independent foot pedal driving device drive system, thus change China Patent No. 201210084957.X in prior art be located at left and right two gearbox outputting powers a to axle on travel in the middle of run into road injustice will cause output shaft one of them wheel of distortion cannot with earth surface, both feet center of gravity of people when treadling can be caused to swing, cannot realize automatically adjusting center of gravity very unstable, foot-operated from running also danger close, entail dangers to personal safety, even likely can cause the distortion of output shaft, gearbox just cannot work, and the shortcomings such as the foot-operated function from running cannot be realized.Bicycle of the present invention is individual drive, very light, very laborsaving when two stretchers that user stand on bicycle are trampled, and running into road injustice can the center of gravity of adjustment people automatically, therefore very steadily and safety.
