Abstract
Chainless-drive device for bicycle, by driving wheel, transmission shaft, flower wheel constitute.Driving wheel is loaded on the axis, and flower wheel is loaded on the backshaft skin, and transmission shaft is vertical with axis.Driving wheel is made of interior driving wheel and outer driver, and transmission shaft is made of two column inserted tooth formula power wheels, castellated shaft and the 3rd column power wheel, the active flank transmission by spherical groove and sphere plush copper between driving wheel and flower wheel and the transmission shaft.Transmission shaft is divided into multistage, intersegmental employing inserted tooth and spline transmission.
Description
The present invention relates to Chainless-drive device for bicycle.
Chinese patent provides a kind of Chainless-drive device for bicycle No. 88205727, it is the driving device that utilizes gear and transmission shaft to form, replace the existing chain gearing of bicycle, it is as shown in Figure 1: it utilizes two pairs of cone gears 2,3 and 5,7 and transmission shaft 4, and the power on the pedal is delivered on the trailing wheel.When stepping on pedal, crank drives bicycle middle shaft 6 rotations, drives driving gear in succession and rotates 7,5, by transmission shaft 4, drives driven gear and rotates 3,2, and backgear 2 backs drive rear axle 1 and rotate, and trailing wheel advances thus, and bicycle is moved ahead.This cone gear working accuracy and installation requirement height, back axle construction and processing technology are complicated.
The invention provides another kind of Chainless-drive device for bicycle, claimed structure is simple, be easy to processing, be easy to dismounting, and ensuring smooth transmission is reliable.
It is made of driving wheel, flower wheel, transmission shaft and shell thereof, and driving wheel is loaded on the axis, and flower wheel is loaded on the backshaft skin, and transmission shaft becomes the upright position respectively with axis and rear axle; Transmission shaft is made of three column power wheels and a spline shaft, first, second column power wheel is by the saw shape inserted tooth engagement of termination separately, constitute power-transfer clutch, second column power wheel other end and spline shaft one end are by spline and spline engagement, and the spline shaft other end and the 3rd column power wheel are fastening; On the wheel face of driving wheel and flower wheel spherical groove is arranged, the sphere plush copper is arranged respectively on the cylinder of the first, the 3rd column power wheel, the corresponding engagement with the sphere plush copper of described spherical groove realizes the transmission between driving wheel and transmission shaft and transmission shaft and the flower wheel thus.
The present invention mainly is made of driving wheel, transmission shaft, flower wheel three parts, and wherein transmission shaft is made up of three column power wheels and a spline shaft, and is simple in structure, is easy to processing and installation; Driving wheel has the bigger transmission arm of force, and ensuring smooth transmission is reliable, and has speed changing function.
Fig. 1 is the driving device scheme drawing of Chinese patent 88205727;
Fig. 2 is the birds-eye view of invention, and as Figure of abstract;
Further specify below in conjunction with accompanying drawing.
See Fig. 2, transmission shaft is made up of column inserted tooth power wheel 4 and 7, spline shaft 8, column sphere double wedge power wheel 9, power wheel 4 termination zig-zag inserted tooths 5 mesh with the zig-zag inserted tooth 6 of power wheel 7 terminations, the spline groove that power wheel 7 second termination inwalls have and the spline engagement of spline shaft 8 one ends, spline shaft 8 other ends and column power wheel 9 are fastening, and power wheel 7 second termination faces have retracing spring 21; On the axis 1 driving wheel is housed, the corresponding one by one engagement of sphere plush copper on the spherical groove that has on the driving wheel wheel face and column inserted tooth power wheel 4 cylinders; Device flower wheel 10 on the backshaft skin, the corresponding one by one engagement of spherical groove that has on the sphere plush copper on column power wheel 9 cylinders and the flower wheel 10.
Above-mentioned driving wheel comprises outer driver 3, interior driving wheel 2, both are linked on the axis 1, spherical groove 15,14 and 23 is arranged respectively on the wheel face of driving wheel 2,3 and flower wheel 10, between interior driving wheel 2 and the outer driver 3 retracing spring 18 is arranged, the groove that the device shift fork is arranged on the interior driving wheel 2, the shift fork 11 that speed-change and gearshift is used wherein is housed, and shift fork 11 is connected with steel wire 12, handle 13 successively.So can carry out speed change.Have the pin 19 and the pin-and-hole 20 of phase fit on the driving wheel 3 and 2.Above-mentioned driving wheel 2 and 3 and the wheel face of flower wheel 10 on have the spherical groove 15,14 and 23 of some, have respectively on the cylinder of column inserted tooth power wheel 4 and column power wheel 9 and above-mentioned spherical groove transmission ingear sphere plush copper 16,17 and 22.
Generally speaking, level land by bike time for example, as long as utilize driving wheel 2 and power wheel 4 engagements, sphere plush copper 16 engagements on the groove 15 on this moment driving wheel 2 and the power wheel 4, by this active flank power transmission, this moment, road speed was fast.Step on pedal and drive axis 1 rotation, drive power wheel 4,7 and castellated shaft 8, power wheel 9, flower wheel 10 in succession, thereby drive the backshaft skin rotation; When climbing, binding lever 13, steel wire 12 drives shift fork 11, with the pin 19 of the pin-and-hole on the driving wheel 2 20 cover on the driving wheel 3,4 pins are generally arranged, yellow 18 compressions of bullet, the groove 15 on the driving wheel 2 is thrown off with the plush copper tooth 16 on the cogwheel 4 at this moment, groove 14 on the driving wheel 3 and 17 engagements of the plush copper on the cogwheel 4, its type of drive is with last identical, because driving wheel 3 radiuses are big, the arm of force is big, so moment is big, it is laborsaving to climb.Decontrol when handle 13, spring 18 is with driving wheel 2 engage a gears, and driving wheel 3 is out of supply.
When descending, pedal is not stepped on, and axis 1 does not rotate, and inserted tooth 5,6 leaves, spring 21 compressions, and trailing wheel moves ahead naturally.Enter the level land when descending finishes, spring 21 recovers elastic force, and inserted tooth 5,6 meshes again, so during contrarotation, inserted tooth 5,6 plays a part power-transfer clutch.
