Abstract
The bicycle has driving mechanism comprising pedal, toothed wheel, chain and flywheel. It features the four toothed wheels and three chains and it has also bearings, bearing housing, speed varying chain wheel, etc. It has three stages of speed varying driving, and thus several times higher speed than common bicycles. The back toothed wheel is much greater than the flywheel, so that the bicycle is power saving. The bicycle has chain wheels and chains for driving and is smooth in driving, high in rigidity, power saving and high in speed.
Description
One, technical field:
The present invention relates to a kind of bicycle drive, particularly disclose a kind of force-saving speed-varying bicycle, belong to a kind of later-model bicycle in the general vehicle.
Two, background technology:
Constantly upgrading as the bicycle that still generally uses in modern's life, the variable speed bicycle immediate development is very fast, its structure majority is the sectional flywheel of various different gear combination, with shift fork chain is engaged with, realizing various speed changes, but there is following shortcoming: the one, be difficult to realize laborsaving; The 2nd, the whole chain cover that little design is supporting with it easily pollutes and corrosion transmission device.And 002,167,050 1 kinds of chain speed changes of patent whole chain cover bicycle, though protective action is arranged, maintenance and structural strength are not enough to some extent; Patent 97204115 Bicycle driving devices, it is provided with the two stage speed change gear on the flywheel rear axle, and there is obstacle in this gear on reliability; 90204156.8 1 kinds of variable speed bicycles that do not have chain gear of patent, it is to the cone gear transmission with some, and the vibration of the structural strength of cycle frame and operation is jolted, and all is difficult to ensure the accuracy and the reliability in gear transmission gap, should not use on bicycle.
Three, summary of the invention:
Problem to be solved by this invention is: design a kind of force-saving speed-varying bicycle that can overcome above-mentioned all deficiencies.
Technical scheme of the present invention is: a kind of force-saving speed-varying bicycle, its transmission comprises pedal stroke, chain wheel, chain and flywheel, it is characterized in that: described chain wheel is provided with four, three on chain, be provided with the right front chain wheel that the number of teeth equates in pedal stroke inboard, step axis two ends, left front chain wheel, the inboard flywheel in addition of the right front chain wheel of captiveing joint with the step axis, the flywheel inner ring is fixed on an end of internal bearing sleeve, internal bearing sleeve is enclosed within on the axis of stamping one's foot, be provided with bearing each other, the left front chain wheel of internal bearing sleeve other end captive joint, the outer bearing sleeve that is fixedly connected on the vehicle frame is enclosed within outside the internal bearing sleeve, bearing is also arranged each other, what be distributed in hind axle Decorative drum both sides is right back speed-changing chain, right back chain wheel and left back large toothed disk, right back speed-changing chain, right back chain wheel is cemented on the same sprocket wheel lining, the lining sky is enclosed within on the rear axle on trailing wheel Decorative drum the right, transmission is provided with right outer chain between right front chain wheel and the right back speed-changing chain, transmission has right interior chain between right back chain wheel and the flywheel, left front chain wheel and left back large toothed disk transmission have left chain, the speed ratio of right front chain wheel and right back speed-changing chain is same or similar in the speed ratio of right back chain wheel and flywheel, and left front chain wheel diameter has only 1/2～1/3 of left back large toothed disk diameter.Because invention has comprised the three-step gear shift transmission, the speed of a motor vehicle of bicycle can improve several times.And left back large toothed disk diameter than the enlarged-diameter of former bicycle freewheel about five times, the principle that is inversely proportional to according to moment equal force and the arm of force, how many point of action radiuses of power enlarges doubly, drive the required power of bicycle rear and what can correspondingly reduce doubly, so the present invention is not only laborsaving but also can speedup.
The present invention has the advantage of stable drive, good rigidly, long service life owing to adopted traditional effective sprocket wheel, chain structure, really realizes the purpose that bicycle not only can be laborsaving but also can speed change.
Four, description of drawings:
The right elevation of accompanying drawing 1 product of the present invention.
The left view of accompanying drawing 2 products of the present invention.
Accompanying drawing 3 is power wheel architecture figure on the hind axle of the present invention.
Accompanying drawing 4 step axis train constructionals drawing of the present invention.
Left back large toothed disk of accompanying drawing 5 the present invention and steel wire trailing wheel are installed connection diagram.
The left back large toothed disk of accompanying drawing 6 the present invention is installed connection diagram with no steel wire trailing wheel.
Five, the specific embodiment:
With reference to the accompanying drawings 1,2 left and right sides steps 13,9 drive right front chain wheel 10, by the right outer chain 8 that is engaged with, the right back speed-changing chain 4 of transmission, the right interior chain 7 of right back chain wheel 3 by being engaged with, the flywheel 15 of the right front chain wheel of transmission inboard, the internal bearing sleeve 19 that the flywheel transmission is connected as a single entity drives the left front chain wheel 12 in step axis 18 left sides, the left back large toothed disk 5 of left front chain wheel ingear left chain 14 transmissions, as previously mentioned, from right front chain wheel transmission flywheel, through the speed change of the identical speed ratio of secondary, if speed ratio 1: 2 then what arrive left front chain wheel is 4 times speed, and then the left back large toothed disk of transmission, owing to adopt sprocket wheel, chain structure, therefore the transmission after the speedup is quite steady, if adopt direct motor drive, then effect is better.
With reference to the accompanying drawings 3, flywheel 15 is rigidly attached to an end outer rim of internal bearing sleeve 19, and 18 of step axis also have bearing, be rigidly connected and also be provided with bearing 16 between the outer bearing sleeve 17 of vehicle frame and internal bearing sleeve, therefore the left front chain wheel that is cemented in the internal bearing sleeve left side also can rotate neatly, by the left back large toothed disk 5 of left chain 14 transmissions, with reference to the accompanying drawings 4, hind axle 24 is overlapping separate right back speed-changing chain 4, right back chain wheel 3 and trailing wheel Decorative drum 25, between be lined with pad 26, right back speed change chain 4 all is cemented on the back sprocket wheel lining 27 with right back chain wheel 3, and 24 on rear axle also is provided with ball, the sprocket wheel number of right back speed-changing chain 4 is more than two or two, and is corresponding to the other speed change fork shift mechanism 11 that is provided with of right back sprocket wheel.With reference to the accompanying drawings 5, left back chain wheel is such with being connected of rear wheel when adopting the steel wire wheel, left back large toothed disk is provided with well-distributed knuckle adapter plate 6 along circumference, the one end is fixed on the chain wheel inside circumference with rivet 21, the other end is fixed on the bearing 22 of steel wire 20 of trailing wheel 1 steel ring 2, accompanying drawing 6 is wheels of no steel wire, and left back chain wheel just directly is fixed on the steel ring support plate 23 with rivet 21.
Case can be installed in the left and right chain periphery of force-saving speed-varying bicycle of the present invention, makes the not only attractive in appearance but also bottom of s trouser leg of not making dirty of bicycle, has stable drive, good rigidly, not only laborsaving but also advantage that can the speed change speedup.
