Description

High-speed bicycle

The utility model relates to bicycle, and especially a kind of additional external energy (oil) that need not does work, and can increase substantially existing bicycle speed, pedals and steps on the labour-saving high-speed bicycle.

Along with progress of human society, rhythm of life is accelerated, and concept of time strengthens, and traffic problems become increasingly conspicuous, but because of densely populated, environmental pollution, all multifactor influences such as economic condition.It is also unrealistic to want to popularize private motor vehicles in short-term.Bicycle is convenient economical, not too take up space, industrially developed country by bike the motion exercise health become a kind of fashion.Along with the enhancing of people's environmental consciousness, bicycle will be used more as a kind of free of contamination short distance walking-replacing tool, and these all provide good chance for the bicycle industrial expansion, and China's bicycle owning amount occupies the first in the world still more.But bicycle running speed is slower, and the effort of riding also is true.The big or small teeth number of sprocket of standard bicycle can't increase than, and crank is pedaled bar and can not be extended again, has so just limited the raising and the effort of speed.Though boosted vehicle energy raising speed alleviates physical demands; But it is a kind of self-propelled vehicle after all, can bring inconvenience to the people when being out of order.

The purpose of this utility model provides a kind of high-speed bicycle, and it can not only improve speed greatly, and can alleviate physical demands, sound construction, simple, and it is comfortable to ride.

The technical solution of the utility model is: seat cushion, front fork and bearing circle, and trailing wheel, front-wheel, hinge wheel, power-transfer clutch, minor sprocket and speed increaser outer ring, sliding sleeve are installed on vehicle frame and the attaching parts thereof, and chain connects large and small sprocket wheel.A bicycle rear minor sprocket and an internally toothed annulus are linked as integral installation on vehicle frame, and a rear-wheel hub and a miniature gears are linked as integral body, are fixed on the vehicle frame internally toothed annulus and pinion by hind axle.When minor sprocket is passed through chain drive by hinge wheel, internally toothed annulus and and then rotation, and by driving the rotation of trailing wheel speedup with its ingear miniature gears.Of the present utility modelly pedal that to step on mechanism be two parallelogram linkage structures that are made of movable rod, the point of crossing of two parallelogram is connected an energy on the sliding sleeve that slides on the bicycle frame pipe, pedal is installed on two parallelogram end points separately, and its other end is connected on the power-transfer clutch of big gear wheel.Pedaling the characteristic of utilizing parallelogram when stepping on, the power arm that both extended is saved muscle power, can move freely in certain angle again, does not disturb mutually, has reached speedup and labour-saving purpose.

The utility model has the advantages that: the speedup system has adopted the internally toothed annulus structure, compact conformation, and volume is little, and speed ratio is big, and installation and processing is convenient.Pedal two parallelogram linkage structures of mechanism's employing, the science, laborsaving stepped on.

The parts code name is consistent in each accompanying drawing

Existing accompanying drawings embodiment.In Fig. 1, seat cushion (1) front fork and bearing circle (3) trailing wheel (5) front-wheel (13), hinge wheel (8) power-transfer clutch (4) minor sprocket and speed increaser outer ring (6) sliding sleeve (12) are installed on vehicle frame and the attaching parts (2) thereof.Chain (7) connects hinge wheel (8) minor sprocket and speed increaser outer ring (6).Movable rod (9) is connected to become two mutually parallelogram of interlock by moving point (10) sliding sleeve (12), and an end is connected on the power-transfer clutch (4), and stretcher (11) is installed on the moving point (10) of movable rod (9).In Fig. 2, minor sprocket and speed increaser outer ring (6) are connected vehicle frame (2) by nut (15) screw mandrel (16) bearing (17) and go up and can rotate.Miniature gears and rear-wheel hub (20) are connected vehicle frame (2) by axle (19) nut (21) bearing (22) (18) jump ring (14) and go up and can rotate.Miniature gears and rear-wheel hub (20) mesh and the formation speed increaser with the internally toothed annulus of minor sprocket and speed increaser outer ring (6).Among Fig. 3, power-transfer clutch (4) is installed in hinge wheel (8) and goes up each movable rod (9) 1,2,3,4,5,6 by each moving point (10) connection, and is installed on power-transfer clutch (4) sliding sleeve (12), and sliding sleeve (12) is gone up crank motion at vehicle frame (2).Stretcher (11) is installed on the moving point (10).Among Fig. 4, the ratchet of power-transfer clutch (4) and hinge wheel (8) are a global facility, and left and right sides pawl body and ratchet (24) are installed on the hinge wheel (8) by gland (23) bearing (25), and are connecting two separate power-transfer clutchs of movable rod (9) composition.

During work, a pin is firmly pedaled and is stepped on stretcher (11) another pin not firmly along with upwards lifting, at this moment down move by two high one side of parallelogram about movable rod (9) moving point (10) formation, low one side upward movement, sliding sleeve (12) is to the direction motion away from hinge wheel (8).When each movable rod of two parallelogram (9), moving point (10) and stretcher (11) are with after sliding sleeve (12) is parallel, continue firmly to pedal to step on, close to hinge wheel (8) again at parallelogram characteristic action low sleeve (12), motion and so forth, two legs alternately firmly drive power-transfer clutch (4) driving hinge wheel (8) and rotate, by chain (7) drive minor sprocket and speed increaser outer ring (6) and with its ingear miniature gears and rear-wheel hub (20) motion, realize speedup and labour-saving purpose.
