Above embodiment is optimum structure of the present invention, is not limiting the scope of the present invention; The scheme that connection mode adjusts to some extent, and do not affect the realization of this goal of the invention.
The fast gear power transmission line of the present embodiment:
External spiral cam 10 → transmission shaft outputting power of the inside spin cam 4a → transmission shaft 1 of the axial external conical sleeve of the axial external conical sleeve 4 → torus of the axial inner conical drogue 5 → torus of power → torus;
Now overriding clutch surmounts, and resistance transfer route: the axial external conical sleeve → compression speed change butterfly spring of inside spin cam → torus of the axial external conical sleeve of external spiral cam → torus of transmission shaft → transmission shaft; Transmission shaft is applied axial force by the external spiral cam of transmission shaft to the inside spin cam of the axial external conical sleeve of torus and the axial external conical sleeve of torus and compresses speed change butterfly spring, when resistance to motion is increased to a timing, this axial force speed change butterfly spring, the axial inner conical drogue of torus is separated with the axial external conical sleeve of torus, power is transmitted by following route, namely keeps off power transmission line slowly:
External spiral cam 10 → transmission shaft outputting power of the inside spin cam 4a → transmission shaft 1 of the axial external conical sleeve of the axial external conical sleeve 4 → torus of outer ring 15 → overriding clutch inner ring, 14 → pendulum-type edge type strainer Meshing Pair → cam pair → torus that the axial inner conical drogue of power → torus 5 → slow gear driving gear 9 → the first slow gear gear 21 → slow gear tween drive shaft 19 → the second keeps off gear 16 → overriding clutch slowly.
Slow gear power transmission line is simultaneously also through following route: pendulum-type edge type strainer Meshing Pair → cam pair → torus axial external conical sleeve 4 → compression speed change butterfly spring, prevent from keeping off slowly in transmission process and occur compression speed change butterfly spring reciprocating compression, thus the axial inner conical drogue of torus and torus axial external conical sleeve laminating when preventing slow shelves transmission.
Above-mentioned transfer route is had to find out, the present invention operationally, the inner conical surface of the axial inner conical drogue of torus and the male cone (strobilus masculinus) of the axial external conical sleeve of torus fit tightly under the effect of speed change butterfly spring, form the automatic transmission that keeps certain pressure, and the required pressure of power-transfer clutch engagement can be adjusted by the axial width increasing speed change axle sleeve, reach transmission object, now, power drives the axial inner conical drogue of torus, torus axial external conical sleeve, transmission shaft, makes transmission shaft outputting power left-hand revolution; Now keep off overriding clutch to be slowly in and to surmount state.
During motor vehicle starting, resistance is greater than propulsive effort, and resistance forces transmission shaft 1 to rotate clockwise certain angle, and under the effect of the external spiral cam 10 of transmission shaft 1, the axial external conical sleeve 4 of torus compresses speed change butterfly spring; The axial external conical sleeve 4 of torus is separated with the axial inner conical drogue 5 of torus, synchronously, slow gear overriding clutch engagement, power drives the axial inner conical drogue 5, first of torus slow gear gear 21, slow gear tween drive shaft 19, second keeps off gear 16, the outer ring 15 of overriding clutch, inner ring 14, pendulum-type edge type strainer Meshing Pair, the axial external conical sleeve 4 of torus and transmission shaft 1 slowly, and transmission shaft 1 outputting power is rotated to keep off speed slowly; Therefore, automatically achieve bottom gear and start, shorten cranking time, decrease starting power.Meanwhile, speed change butterfly spring absorbs movement resistor moment energy, stores standby potential energy for recovering gear transferring power soon.
Start successfully, resistance to motion reduces, when component is reduced to less than the pressure that speed change butterfly spring produces, produce under speed change butterfly spring pressure discharges promotion rapidly because the compression of passive movement resistance, the inner conical surface of the male cone (strobilus masculinus) and the axial inner conical drogue 5 of torus that complete the axial external conical sleeve 4 of torus recovers to fit tightly state, and slow gear overriding clutch is in and surmounts state.
In driving process, along with the change self shifter principle of resistance of motion is the same, realizing variable block when not needing to cut off propulsive effort, make whole locomotive operation steady, safe and low consumption, and transfer route being simplified, improving driving efficiency.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
