Abstract
The utility model discloses a bicycle automatic stepless speed variator, which is a mechanical speed change mechanism which can adjust the transmission speed ratio and the moment of the bicycle by itself according to the road and resistance situation. The bicycle automatic stepless speed variator comprises a control panel, a driving panel, a unidirectional satellite wheel, a balance spring, a vibration reduction pressure spring, a chain shield, etc., which are arranged on one side of the joint of the bicycle frame, a single chain wheel flywheel and two spring tension wheels which are arranged on the rear wheel. The utility model has the advantages of simple device, convenient operation, and that the stepless speed change automatically proceeds.
Description
The utility model relates to a kind of automatic stepless speed-changing device for bicycle, belongs to the wheeled car speed-changing mechanism technical field that rider drives.
Bicycle is riding instead of walk and transportation means of using always of people, for laborsaving and rationally ride, various bicycle gearshifts is arranged.Existing bicycle speed-varying unit all needs to pedal with the control stalk on the hand operation handlebar or with before and after the pedal usually, just can hang up needed shelves, the ability engage a gear of also will using both hands and feet that has, " the 15 grades of bicycle speed-varying units " introduced as " world inventions " magazine 1986 the 4th phases back cover is exactly speed change like this, and be step change, be difficult to accomplish that steadily even the slipping over of change in torque cross.
The purpose of this utility model provides a kind of no longer the needs with hand or with the automatic stepless speed-changing device for bicycle of foot control system engage a gear.
The utility model is achieved in that it includes a strand flying wheel and two driving systems that spring tension pulley is formed of being adorned on parts such as control panel, driving disk, unidirectional satellite wheel and wheel shaft, balance pull-spring, vibration damping stage clip and chain, plate washer and the trailing wheel by what ordinary bicycle vehicle frame center tap (five-way) side was adorned.Six arcuate furrows that can produce centripetence are wherein arranged on the control panel, 6 radially straight valley gutters that can produce centrifugal effect are arranged on the driving disk of installing side by side with control panel, and the wheel shaft of 6 unidirectional satellite wheels just is through in 6 grooves of control panel and driving disk respectively, chain ring forms drive sprocket around the outside of 6 unidirectional satellite wheels, because of unidirectional satellite wheel shaft can move in groove, thereby the diameter that changes drive sprocket realizes stepless change.Also having 6 one ends to be fastened on the driving disk wheel rim on the driving disk, the other end is hooked on the balance pull-spring on the unidirectional satellite wheel shaft, its effect is the power of pedaling according to the resistance to motion of wheel and pin, unidirectional satellite wheel is remained in two grooves that coil take turns on the path position arbitrarily.Ride people and to go up a slope or to ride down with the wind, when feeling that resistance is big, because the tightening force of chain and the internal pressure of control panel deep-slotted chip breaker, automatically unidirectional satellite wheel shaft is pressed to the axle center by disturbing, make the wheel of sprocket wheel directly narrow down to a suitable position, people can be pedaled by bike trippingly, and when ride downhill path or when riding with the wind, balance pull-spring can be automatically be moved the unidirectional satellite wheel diameter of axle outside to a correct position, make ride more brisk fast.
The utility model structure also is fairly simple.Only be contained in tens of axis parts in addition, have only a strand flying wheel and two spring tension pulleys on the rear axle, cancelled heavy 5 or 6 backgear groups that sprocket wheel is formed, rear axle can be the same with ordinary bicycle.The utility model both can be used for making new car, also was applicable to the repacking of existing bicycle fully, only needed therein shaft portion to be equipped with this device and two spring tension pulleys of rear axle increase get final product.Wide adaptability.And because of carrying out stepless change automatically, need not learn and train, all-ages, easy to use, it is comfortable to ride.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the plane exploded view of control panel of the present utility model and driving disk.
Below in conjunction with accompanying drawing the utility model is described further.
1 is vehicle frame center tap (five-way) among Fig. 1, the 2nd, and axle sleeve, the 3rd, locknut, the 4th, ring washer, the 5th, driving disk, the 6th, adjusting disk, the 7th, control panel, the 8th, satellite one-way wheel, the 9th, one-way wheel wheel shaft, the 10th, sheet spring, the 11st, ring washer, the 12nd, adjusting disk, the 13rd, drag hook, the 14th, balance pull-spring, the 15th, plate washer, the 16th, control panel flange, the 17th, rivet, the 18th, pedal flange, the 19th, right crank, the 20th, crank pin, the 21st, damper spring.Fig. 1 also is a structure assembly drowing of the present utility model, has shown the each several part assembly relation of part in addition.Axle sleeve 2 is a bearing fit with axis, and change-speed box main part control panel 7 and driving disk 5 in addition are housed on the axle sleeve 2, and with locknut 3 fastening it.In the middle of the groove of these two dishes, be installed with the wheel shaft 9 of unidirectional satellite wheel, one side of wheel shaft be equipped with can only unidirectional rotation supporting chain and the unidirectional satellite wheel 8 of transferring power, the opposite side of this wheel shaft is equipped with drag hook 13 and balance pull-spring 14, and its effect is to reach stepless change according to resistance of riding and the position that the power of pedaling changes wheel shaft automatically.Control panel flange 16 is tightened to one with control panel 7 usefulness rivets 17 and is locked on axle sleeve 2.The effect of plate washer 15 is to guarantee that balance pull-spring is normally flexible and prevent that trouser legs are involved in.Between in control panel flange 16 3 or 4 dividing plates 3 or 4 damper springs 20 are housed.The effect of damper spring 20 is inhomogeneous moments of torsion that buffering pedal, crank transmit.The messenger chain of this device is such: by stressed 3 or 4 the protruding dividing plate → control panels 7 → unidirectional wheel shaft 9 → unidirectional satellite wheel 8 → chain → rear flywheel → trailing wheel that reaches in crank 18 → damper spring 20 → control panel flange 16 of pedal.Plate washer 15 usefulness sheet metals are made.
Fig. 2 also is the front view after this change-speed box is removed plate washer 15.Shown among the figure to be evenly distributed with 6 helical arcuation grooves on the control panel 7, and be evenly distributed with 6 radially straight valley gutters of radiation-like on the driving disk 5 in its lower section that the wheel shaft 9 of unidirectional satellite wheel just is through between the groove of two dishes.And hook wheel shaft by balance pull-spring 14 and outwards pull.When ride upward slope or resistance were big, wheel shaft just moved in axis direction; And when ride descending or resistance reduced, the tractive mono-directional wheel shaft moved laterally under the effect of balance pull-spring, made bicycle running speed and the torque can be according to road and resistance stepless change voluntarily, and rider keeps brisk sensation of riding.Among the figure 22 be the unidirectional wheel shaft of balance pull-spring tractive in outermost position, 23 positions that are the unidirectional wheel shaft of balance pull-spring tractive in the most close axis axle center.
