The fast retaining power transmission line of present embodiment:
The axial external cone plate 29 → cam pin of the axial inner cone dish of rotor → torus gear ring 27 → torus 31 → transmission shaft 1 → clutch block 22a → clutch gear ring 33 → engagement circle 22b → gear frame 17 → wheel 14.
Slowly keep off power transmission line:
The axial inner cone dish of rotor → torus gear ring 27 → slowly keeps off gear 13 → keep off slowly transmission shaft 12 → keep off slowly overriding clutch 15 → keep off the slowly axial external cone plate 29 → cam pin of gear ring 16 → transmission gear 25 → torus 31 → transmission shaft 1 → clutch block 22a → clutch gear ring 33 → engagement circle 22b → gear frame 17 → wheel 14.
Fast retaining of the present invention transmits the resistance transfer route and retaining transmission resistance transfer route is opposite with power transmission line slowly.
Simultaneously, resistance also passes through following route: the axial external cone plate 29 of transmission shaft 1 → cam pin 31 → torus → compression speed change spring 5.
This change-speed box is when operation, the inner conical surface of the axial inner cone dish of torus gear ring 27 and the male cone (strobilus masculinus) of the axial external cone plate 29 of torus fit tightly under 5 effects of speed change spring, form an automatic transmission that keeps certain pressure, and can enclose 6 thickness by the adjustment of increase prestress and adjust the required pressure of clutches engaged, reach the transmission purpose, at this moment, rotor drives the axial inner cone dish of torus gear ring 27, the axial external cone plate 29 of torus, cam pin 31, transmission shaft 1, clutch block 22a, clutch gear ring 33, engagement circle 22b, gear frame 17 makes wheel 14 left-hand revolutions.Slowly keeping off overriding clutch this moment is in and surmounts state.
Resistance is greater than propulsive effort during motor vehicle starting, and resistance forces transmission shaft 1 to clockwise rotate certain angle, and under the effect of cam path 1a, cam pin 31 drives the axial external cone plate 29 compression speed change springs 5 of torus to the direction motion of compression speed change spring 5; The axial external cone plate 29 of torus separates with the axial inner cone dish of torus gear ring 27, synchronously, slowly keep off the overriding clutch engagement, the driving motor rotor drive the axial inner cone dish of torus gear ring 27, slowly keep off gear 13, slowly keep off transmission shaft 12, slowly keep off overriding clutch 15, keep off gear ring 16, transmission gear 25, the axial external cone plate 29 of torus, cam pin 31, transmission shaft 1, clutch block 22a, clutch gear ring 33, engagement circle 22b, gear frame 17 slowly, wheel 14 is rotated with retaining speed slowly; Therefore, realize the bottom gear starting automatically, shortened cranking time, reduced starting power.Meanwhile, speed change spring 5 absorbs movement resistor moment energy, holds potential energy fully for recovering soon the gear transferring power.
After starting successfully, resistance to motion reduces, when component is reduced to less than in the speed change butterfly spring automatic transmission that speed change spring 5 produced pressure, because of producing speed change spring 5 pressure, the compression of passive movement resistance discharges promotion rapidly down, the inner conical surface of finishing the male cone (strobilus masculinus) of the axial external cone plate 29 of torus and the axial inner cone dish of torus gear ring 27 recovers to fit tightly state, keeps off overriding clutch slowly and is in and surmounts state.
In the reversing process, by external force reversing clutch push rod 22 is moved to pull back spring 22c direction, make clutch gear ring 33 and engagement circle 22b jump out of mesh, wheel 14 can freely rotate; Simple to operation.
In the driving process,, realize variable block not needing to cut off under the situation of propulsive effort, make whole locomotive operation steady along with the variation self shifter principle of resistance of motion is the same, safe and low consumption, and also transfer route oversimplifies, and improves driving efficiency.
