Description
Technical field
The utility model relates to the drive system structure field of bicycle, is specially the automatic labour saver of bicycle.
Background technology
Bicycle is a kind of light vehicle easily, and its principle is to use manpower to pedal to step on stretcher, drives axis and drives central large fluted disc, by chain, transmission of power is arrived the rear portion flywheel, drives at last trailing wheel bicycle is advanced.Due to its simple advantage efficiently, become a kind of manpower traffic machinery that has a large capacity and a wide range.
Because the deadweight of bicycle is less, the power-assisted of therefore riding is mainly derived from the friction of rolling that bicyclist's body weight and load-carrying bring and the upward slope power-assisted when going up a slope.Compare the zero load of bicycle and ride, the twice when the required propulsive effort of load-carrying 90Kg approximately is zero load; When the gradient reaches 15 when spending, the twice when the required propulsive effort that goes up a slope also will reach zero load.This is the huge challenge of bicyclist's muscle power for the bicycle that does not possess the no-load voltage ratio function.General variable speed bicycle by controlling the switching of chain on sprocket wheels at different levels, changes the transmitting ratio of sprocket wheel, to reach the labour-saving effect.This scheme exist due to lost efficacy after the long-term outdoor use of executive component, can not be according to shortcomings such as road conditions and operating mode automatic switchover transmitting ratios.
Summary of the invention
For the problems referred to above, the utility model provides bicycle automatic labour saver, and it makes the work-saving device of bicycle outside not exposed, guarantee that device is permanently effective, and it can automatically switch according to road conditions and operating mode, need not manual shift, and is convenient, convenient, stable, reliable.
the automatic labour saver of bicycle, its technical scheme is such: it comprises foot-operated, pedal connecting rod, imput shaft, main actuating sleeve, the output sleeve pipe, front sprocket wheel, the mouth that input end is respectively installed with described pedal connecting rod is exposed in the both sides of described imput shaft, the input end of described pedal connecting rod is equipped with described foot-operated, the end that described imput shaft is positioned at seal case is set with described main actuating sleeve, described main actuating sleeve connects the input end of described output sleeve pipe by drive mechanism, described output sleeve pipe is loaded on by bearing carrier ring the other end that described imput shaft is positioned at seal case, the mouth of described output sleeve pipe is set with described front sprocket wheel, it is characterized in that: described drive mechanism specifically comprises secondary actuating sleeve, driven shaft, described secondary actuating sleeve is set in described imput shaft, described secondary actuating sleeve a side and a side of described main actuating sleeve be connected with a joggle by single fixed angle screw inclined plane, spring top is loaded on the opposite side of described secondary actuating sleeve, described spring housing is loaded on described imput shaft, the two ends of described driven shaft are loaded on the biside plate of described seal case by bearing, described seal case is with imput shaft, driven shaft is wrapped in inside, be respectively installed with high speed gear on the input end of described driven shaft, low speed gear, described high speed gear, spacing distance is arranged between low speed gear, the outer ring surface of described secondary actuating sleeve is specially the combination of the gear of two groups of different-diameters, it comprises and described high speed gear gears in mesh I, with described low speed gear gears in mesh II, described gear I, the gear II is along high speed gear, arranging discharged to correspondence successively of low speed gear, the mouth of described driven shaft is set with the secondary driving wheel, the described secondary sprocket gear described secondary flower wheel that is connected with a joggle, described secondary flower wheel is set in the input end of described output sleeve pipe.
It is further characterized in that:
The end face towards described secondary actuating sleeve of described output sleeve pipe is provided with spacing end face, is provided with spring between the opposite side of described secondary actuating sleeve and described spacing end face, and described spring housing is loaded on described imput shaft;
The cover holding position of described high speed gear, low speed gear and described driven shaft is respectively arranged with overriding clutch.
After adopting structure of the present utility model, owing to being arranged on main actuating sleeve on imput shaft and secondary actuating sleeve mutually with the inclined-plane engagement of single fixed angle, so the rider is applied on imput shaft radially torsion, can be decomposed into axial propelling thrust and two kinds of power of torsion radially on the mesh inclined plane of main actuating sleeve and secondary actuating sleeve, this decomposition of force ratio is by the angle decision of mesh inclined plane, and its decomposition ratio is constant.When load increases in bicycle running, the radially torsion that is applied on imput shaft also must increase, the axial thrust that decomposes on mesh inclined plane also can increase accordingly, so the axial thrust on being applied to secondary actuating sleeve mesh inclined plane is during greater than the pressure of spring, relative displacement will occur in the mesh inclined plane of main actuating sleeve and secondary actuating sleeve, and secondary actuating sleeve will under the effect on inclined-plane, endwisely slip along imput shaft, make the engagement of driving tooth wheels and low speed gear, reach the labour-saving purpose; And because described seal case is wrapped in inside with imput shaft, driven shaft, it makes whole device all be positioned at seal case inside, makes it outside not exposed, guarantees that device is permanently effective; To sum up, it makes the work-saving device of bicycle outside not exposed, guarantees that device is permanently effective, and it can automatically switch according to road conditions and operating mode, need not manual shift, and is convenient, convenient, stable, reliably.
