The stepless speed changing bicycle can realize the stepless speed change of the bicycle through belt drive. The utility model has the advantages of stable transmission, low noise, convenient speed regulation and operation, and large speed changing range. Simultaneously, the stepless speed changing bicycle has the advantages of simple structure and easy machining, and the large scale mass production can be implemented.
Description
Technical field the utility model relates to a kind of bicycle, particularly a kind of strap drive bicycle with stepless speed change.
The background technology bicycle with stepless speed change is subjected to people's favor with the advantage of uniqueness.Data shows that the researchist has made some designs, and the patent of passing through that has is published.Disclosed bicycle with stepless speed change all adopts structure realization stepless changes such as Chi Lun Chi Tiao quadrant gear mostly, because this class transmission device is comparatively complicated, processing difficulties, expense are also than higher.So being not suitable for Quantity production sells.Therefore also there is not bicycle with stepless speed change to appear on the market in the market.
Utility model content the technical problems to be solved in the utility model is: the transmission device to existing bicycle with stepless speed change improves the large-scale production bicycle with stepless speed change.
The bicycle with stepless speed change that the utility model provides, the Power train that it is characterized in that bicycle comprises with lower member: little driving wheel, little fixed wheel, petty action wheel shift fork, little driving wheel, little fixed wheel are tapered, two-wheeled size shape unanimity, the conical surface is relative, form the little power wheel that has vee-cut, captive joint with the flywheel axle sleeve on the bicycle rear axle, little driving wheel slides at fork controls lower edge axle; Big driving wheel, big fixed wheel, big driving wheel shift fork, big driving wheel, big fixed wheel are also tapered, two-wheeled size shape unanimity, the conical surface is relative, forms the large drive wheel that has vee-cut, is fixed on the bicycle middle shaft, and big driving wheel slides at fork controls lower edge axle; V-type driving band, V-type band tightening device, governor, brake cable, flywheel, the V-type driving band is set in the groove of big steamboat; V-type band tightening device is contained on the rear axle, and its bogie wheel supports driving band; Governor is contained near the handlebar, is connected with brake cable, and brake cable drives the shift fork of regulating big or small driving wheel position; Flywheel is made of flywheel axle sleeve, flywheel base, roller, ball, is contained on the rear axle, is close to little power wheel, and the flywheel axle sleeve is captiveed joint with the brief biography driving wheel, and flywheel base is captiveed joint with rear axle, also is provided with the fleetline groove in the flywheel axle sleeve, and roller is placed in the groove.
Bicycle with stepless speed change is realized speed change by following process: governor pulling brake cable, brake cable drives little shift fork and compresses little driving wheel, make it vertically near the little fixed wheel on same axle, distance between the two-wheeled is reduced, the groove that the two-wheel conical suface is become narrows down, belt will move at the edge to little driving wheel under the effect of centnifugal force and thrust, increase the radius of little power wheel.Meanwhile, big shift fork will be regulated big driving wheel away from the big fixed wheel on same axle, and the two-wheeled spacing is increased, two conical surfaces institute clip slot broadens, and driving band will move along the axis direction of the conical surface to large drive wheel, thereby the large drive wheel radius is reduced, this moment, the transmitting ratio of bicycle reduced, and the speed of a motor vehicle slows down.Opposite operating process will realize that transmitting ratio becomes big, and the speed of a motor vehicle is accelerated.Because the radius of big or small power wheel can be regulated arbitrarily,, thereby realized stepless change so the transmitting ratio of bicycle can regulated at will.
The flywheel working process of bicycle with stepless speed change is: when belt is just changeing, roller in the flywheel axle sleeve stream line pattern groove will be stuck owing to gravity and friction move to the narrow place of groove, flywheel axle sleeve and flywheel base are become one, the flywheel axle sleeve will drive flywheel base and rear wheel rotates, roller during the belt pulley reversing in the flywheel shaft grooving will roll the place to the groove inner width, at this moment, roller and axle sleeve reversing and flywheel base and bicycle rear continue just to change.
The utility model is compared with existing bicycle with stepless speed change, and its remarkable advantage is: realize the stepless change of bicycle by strap drive, stable drive, noise is low, speed governing is easy to operate, speed range is big; Simultaneously this bicycle with stepless speed change simple in structure, be easy to processing, can realize extensive stock production.
Description of drawings Fig. 1 is bicycle with stepless speed change keystone configuration scheme drawing (stretcher, car ladder, after-frame omit); Fig. 2 is a flywheel structure front view scheme drawing (end cap omits); Fig. 3 is a flywheel structure front view scheme drawing (end cap omits).
The motivation transfer motion part of specific embodiment bicycle with stepless speed change comprises: governor 1, brake cable 2, big fixed wheel 3, big driving wheel 4, big driving wheel shift fork 5, V-type driving band 6, V-type band tightening device 7, petty action wheel 8, flywheel 9, petty action wheel shift fork 10, little fixed wheel 11.Little fixed wheel is tapered, two-wheeled size shape unanimity, and the conical surface is relative, forms the little power wheel that has vee-cut, captives joint with the flywheel axle sleeve on the bicycle rear axle, and little driving wheel slides at fork controls lower edge axle; Big driving wheel, big fixed wheel are also tapered, two-wheeled size shape unanimity, and the conical surface is relative, forms the large drive wheel that has vee-cut, is fixed on the bicycle middle shaft, and big driving wheel slides at fork controls lower edge axle.The V-type driving band is set in the groove of big or small two power wheels, and V-type band tightening device is contained on the rear axle, and its bogie wheel supports driving band.Governor is contained near the handlebar, is connected with brake cable, and brake cable drives the shift fork of regulating big or small driving wheel position.
The flywheel 9 of bicycle with stepless speed change is made of flywheel axle sleeve 12, flywheel base 14, roller 13, ball 15, is contained on the rear axle, is close to steamboat, the flywheel axle sleeve is captiveed joint with steamboat, flywheel base is captiveed joint with rear axle, also is provided with fleetline groove 16 in the flywheel axle sleeve, and roller is placed in the groove.
Regulate governor 1 and drive brake cable 2, make petty action wheel shift fork 10 compress petty action wheel 8, make it near little fixed wheel 11, make brief biography driving wheel radius become big, V-type band 6 moves to petty action wheel edge.Simultaneously big shift fork 5 loosens, and makes big driving wheel 4 away from big fixed wheel 3, and V-type band 6 is moved to axis direction, and radius reduces, and this moment, transmitting ratio reduced.7 guarantees of V-type band tightening device provide constant tensile force for the V-type band.Opposite operating process can realize that transmitting ratio becomes big.The effect of flywheel 9 is the same with existing flywheel functions, when driving band just changes, roller 2 will move and will be stuck to the narrow place of the stream line pattern groove in the flywheel axle sleeve 1, and the flywheel base 3 and the flywheel axle sleeve 1 of its outside are become one, and the flywheel axle sleeve will drive flywheel base and rear wheel rotation.When driving band reverses, roller 2 will move to the place of the stream line pattern groove width in the flywheel axle sleeve 1, and the flywheel axle sleeve 1 of flywheel base 3 and its outside separate, and at this moment, roller reverses with axle sleeve and flywheel base and bicycle rear continuation are just changeed.
