Abstract
A power-saving gearing for manpower bicycle and tricycle has between the driving gear and the driven reducing gear, a driven speed increasing flywheel on the second shaft and meshed with the driving gear, one speed increasing gear on the third shaft and meshed with the driving gear on the second shaft, a driving rotation disc on the third shaft and with push-pull rod connected with a force-saving lever, a push-pull rod in the driven end of the force-saving level and connected with driven rotation disc on the fourth shaft, and one driven gear on the four shaft and meshed with the driven reducing gear on the back shaft. The present inventino can reduce the action of various resistances on the pedal force during riding the vehicle.
Description
The present invention relates to a kind of improved human powered vehicle driving device, particularly a kind of driving device that can alleviate human powered vehicle various resistances under steam to the foot-operated power load of cyclist is suitable for bicycle, three-wheel vehicle use.
The transmission system of existing bicycle, three-wheel vehicle mainly is made up of drive sprocket, driving chain, passive flywheel.In the bicycle drivetrain that wherein has speed-changing mechanism is installed, the human powered vehicle transmission system of selling on the market is exactly this form.When travelling, step on riding on the crank by cyclist's foot-operated power, drive sprocket is rotated, by driving chain turning effort is passed to passive flywheel, to drive trailing wheel, impel vehicle to overtake.But, go up a slope, against the wind, various resistances such as load is big travel when big, though the bicycle that has is equipped with speed-changing mechanism, can suitably adjust increase and be defeated by the torque of flywheel from drive sprocket by driving chain, but when increasing torque, reduced transmission speed ratio again, lowered moving velocity, like this, want vehicle and run much faster, that have to add the frequency that steps crank hurry up, this has just strengthened the consumption to cyclist's muscle power, the bicyclist is seemed and require great effort that moving velocity is slow again, and this just gives by bike that personnel bring certain difficulty.
The objective of the invention is to provide a kind of improved human powered vehicle driving device---power saving driver for man power vehicle, it can alleviate the load of human powered vehicle various resistances under steam to the foot-operated power of cyclist easily.
Technical solution of the present invention is to be provided with driving gear and involuntary speed reduction gear, and its special character is to have between driving gear and involuntary speed reduction gear and second passive speedup flywheel of driving gear ingear.Respectively there are a passive multiplying wheel and active rotating disk in the both sides of third axle.The passive multiplying wheel engagement of the driving gear of second opposite side and third axle, the active rotating disk of third axle is provided with upside and is connected with laborsaving lever drive end, downside and third axle be rotating disk bonded assembly pull bar initiatively, laborsaving lever Partner is provided with upside and is connected with laborsaving lever Partner, downside and the 4th passive rotating disk bonded assembly pull bar, the driving gear of the 4th opposite side and vehicle rear axle involuntary speed reduction gear mesh.
Described second passive speedup flywheel, its concrete structure is identical with the existing flywheel structure that is installed in bicycle rear axle, and its laborsaving lever is a fulcrum with the rest pin that is fixed on the vehicle frame.Push away and block bar and be provided with the adjustment nut that to adjust its length.
The present invention also can with the supporting use of existing internal speed variator of bicycle.
The present invention is owing to be connected with multiplying wheel, laborsaving lever between driving gear and involuntary speed reduction gear.So when travelling, step riding on the crank, foot-operated strength improves the work speed that it passes to laborsaving lever through multiplying wheel, foot-operated strength after will being amplified by laborsaving lever is again passed to the involuntary speed reduction gear, lower rotating speed by the involuntary speed reduction gear, improve the torque that it drives trailing wheel, make vehicle overcome resistance to overtake, so can allow to obtain bigger turning effort, can alleviate the purpose of human powered vehicle various resistances under steam to the foot-operated power load of cyclist so just reached with the power of economizing.Vehicle rear axle of the present invention is passive to be subtracted and connects gear and the 4th driving gear engagement, because of the involuntary speed reduction gear different with existing vehicle rear axle flywheel structure, the two-way rotation of involuntary speed reduction gear energy.In the middle of riding, laborsaving lever, multiplying wheel instead rotation by the vehicle rear wheel band, when stepping on foot-operated the interruption, because with second passive speedup flywheel of driving gear ingear, its structure is with to have the bicycle rear axle flywheel structure now identical, fuse can only rotate to a direction, so when the active rotating disk of third axle rotates with fast speeds, can not have influence on driving gear crank is rotated, when stepping on once more, because the force of inertia of multiplying wheel, lever can make riding of bicyclist more light.
Below in conjunction with the description of drawings embodiments of the present invention.
Accompanying drawing is a structural representation of the present invention.
The driving gear (1) of making one with crank is arranged with reference to accompanying drawing: imput shaft A, passive speedup flywheel (2) engagement on driving gear (1) and second B, the concrete structure of passive speedup flywheel (2) is identical with the flywheel structure of existing bicycle rear axle, and fuse can only rotate to a direction.Opposite side on second B have with third axle C on passive multiplying wheel (4) ingear driving gear (3), the other end of third axle C has initiatively rotating disk (5), rotating disk (5) is provided with upside and is connected with laborsaving lever (8) drive end, downside and rotating disk (5) bonded assembly pull bar (6), the adjustment nut (7) that can adjust its length is arranged on pull bar (6), laborsaving lever (8) Partner has upside to be connected with laborsaving lever (8) Partner, passive rotating disk (12) bonded assembly pull bar (10) on downside and the 4th D, the adjustment nut (11) that can adjust its length is arranged on pull bar (10), and laborsaving lever (8) is a fulcrum with the rest pin (9) that is fixed on the vehicle frame.Opposite side driving gear (13) on the 4th D and rear axle E involuntary speed reduction gear (14) engagement.
Driving gear (1) and passive speedup flywheel (2), driving gear (3) and passive multiplying wheel (4), and the speedup transmitting ratio of driving gear (13) and involuntary speed reduction gear (14), step-down ratio, the big I of laborsaving lever (8) power arm, resistance arm is decided according to the actual conditions needs of vehicle.
When travelling, step on foot-operated, foot-operated strength drives second B through driving gear (1), the gear of third axle C rotates, the gear transmission of second B of cause and third axle C is speedup and rotates, active rotating disk (5) on the third axle C promptly obtains rotating speed faster, thereby the catch bar (6) on the rotating disk (5) promptly makes progress with the drive end of the laborsaving lever of fast speeds push-and-pull (B), move down, so the Partner of lever (8) is on lever (8) drive end, under the following migration, make the pull bar (10) on the Partner of lever (8), spur the passive rotating disk (12) of the 4th D, impel passive rotating disk (12) to rotate, and the driving gear (13) that passes through the 4th D opposite side drives involuntary speed reduction gear (14) rotation of rear axle E, drive trailing wheel, make vehicle overcome resistance to overtake.
