The specific embodiment
Referring to Fig. 1, a kind of whole axis of bicycle twin shaft interlock comprises driving axis 1 and middle shaft housing 3; Between described driving axis 1 and the middle shaft housing 3 sleeve 2 is installed; The cylindrical two ends of described driving axis 1 are separately installed with and drive bottom bracket bearing 7, and the outer retaining 10 of the bottom bracket bearing of driving is arranged between the two bearings outer ring, and by driving bottom bracket bearing circlip 16 and driving the end that bottom bracket bearing packing ring 17 is positioned the endoporus of sleeve 2; In the other end of endoporus; Retaining 6 lockings drive axis 1 in screwing in, and the cylindrical two ends of sleeve 2 are separately installed with cover axle bearing 9, and the outer retaining 11 of cover axle bearing is arranged between the two bearings outer ring; One end of sleeve 2 is spacing with components and parts erection work platform 4; In the shaft housing 3, an end of middle shaft housing 3 was equipped with circular nut 12 through outside thread during the other end was fixed in through the cover axle bearing circlip 14 on the shaft housing 3 in being installed in, and another end is equipped with components and parts erection work platform 4; Install on the described components and parts erection work platform 4 and be provided with signal output part sub-interface 18.
According to Fig. 1, Fig. 2 production process of the present invention is described:
Set forth the specific embodiment of the present invention according to Fig. 1, Fig. 2:
The present invention is packed in the bicycle center tap, fix with vehicle frame center tap end face with circular nut 12, the sprocket crank of bicycle is loaded onto at the two ends that drive axis 1; Through the flywheel of cycle chain connection trailing wheel, when the external force cw drives axis 1, drive axis 1 through driving bottom bracket bearing 7; In the hole of sleeve 2, rotate, this moment, the pulling force of chain produced tractive force to bicycle, also produced Backlash to driving axis 1 simultaneously; Because the variation of tractive force, the Backlash size of the driving axis 1 of conduction chain also changes, and is through driving in the hole that bottom bracket bearing 7 is contained in sleeve 2 because drive axis 1; Again because sleeve 2 is loaded in the hole of middle shaft housing 3 through cover axle bearing 9; Force in sleeve 2 simultaneously so drive the Backlash of axis 1, again because the restriction of circle in the middle shaft housing 3 forces sleeve 2 to change the rectilinear direction of Backlash; Make sleeve 2 in the interior circle of middle shaft housing, do radially wobbling of trace; Big and little according to the bicycle tractive force, it is also different to give the recoil size that drives axis 1; The radially wobble angle of sleeve 2 in middle shaft housing 3 also changes thereupon, utilizes this principle, at an end of the components and parts erection work platform 4 of sleeve 2; With the medium connection that radially wobbles displacement signal that sleeve 2 constantly changes of accepting that is installed in the components and parts erection work platform 4; Convert the voltage signal of continuous variation to through medium, voltage signal is the terminal by signal output part sub-interface 18, with extraneous power supply; Motor control system connects, thereby realizes the object of the invention.
Referring to Fig. 4 and Fig. 5, in the another kind of embodiment that the present invention provides, the center of circle a of the excircle of said sleeve 2 and the center of circle b of inner periphery are dislocatedly distributed.The spacing L of the center of circle a of the excircle of said sleeve 2 and the center of circle b of inner periphery is 1.5mm-10mm.Present embodiment is 2.5mm.The wall thickness of said sleeve 2 of the present invention is grading structures, and the pivot center of said driving axis 1 is different with the axle center of said middle shaft housing 3, and promptly said driving axis 1 is to be eccentrically set in the said middle shaft housing 3.This off-centre is arranged so that and drives axis 1 when stressed rotating, and can drive said sleeve 2 swings according to the size of tractive force.Certainly, the mode that driving axis 1 drives sleeve 2 has a variety of, also can adopt other version.For example, through adjustment friction force between the two, perhaps both are provided with flexible connection structure.Main purpose is can make sleeve 2 swings in order to drive axis 1.
Referring to Fig. 3; In the foregoing description that the present invention provides; The magnetic end instr 103 that said medium comprises moment arm 101, is arranged on the magnetic part 102 on the said moment arm 101 and matches with said magnetic part 102; Said magnetic end instr 103 is installed on the said components and parts erection work platform 4, and said sleeve 2 is connected with said moment arm 101.Magnetic part 102 described here is a magnet; Said magnetic end instr 103 is a Hall element; 101 swings of said sleeve 2 drive moment arms; Thereby the relative position of adjustment magnetic part 102 and said magnetic end instr 103, through magnetic end instr 103 can the perception tractive force size, transfer in the control system thereby will react the big or small electric signal of tractive force.
Referring to Fig. 3; In the foregoing description that the present invention provides; Said components and parts erection work platform 4 is provided with spacing push rod 41 and is sleeved on the spring 42 on the said spacing push rod 41, and said spacing push rod 41 matches with the free end of said moment arm 101 through said spring 42.41 pairs of moment arms 101 of said spacing push rod play spacing effect, prevent that its oscillating quantity is excessive.Said spring 42 can make moment arm reset.
Referring to Fig. 3, in the foregoing description that the present invention provides, the arranged outside of said moment arm 101 has disc sensor 104, and the disk 105 in the said disc sensor 104 is connected with said driving axis 1.Said disc sensor 104 plays the effect of auxiliary detection, judges whether rotating, it is moving to prevent false touch if driving axis 1.
Other structures and first embodiment of present embodiment are identical.
Those skilled in the art's simple change and replacement in this area all are within protection scope of the present invention.
