Embodiment
The present invention mainly by input shaft 1, duplicate gear 2, sun gear 3, planet carrier 4, fixedly toothholder 5, driving gear 6, right output shaft 7, cross opinion 8, free gear 9, sliding gear collar 10, toothholder 11, planet wheel 12, ring gear 13, driven gear 14, left output shaft 15 etc. and form, embodiment is as follows:
1, duplicate gear 2 empty sets are on input shaft 1, can rotate freely on input shaft 1 and mesh with follower 14, driven gear 14 is fixed on left output shaft 15, drive left output shaft 15 rotations, 3 of sun gears are fixed on input shaft 1, together rotate with input shaft 1, planet wheel 12 is arranged on planet carrier 4, it meshes with sun gear 3 and ring gear 13 simultaneously, be processed with circular groove on ring gear 13 and horizontally slip, mesh simultaneously with planet wheel 3 and duplicate gear 2 left, neutral position and planet carrier 4 and planet wheel 3 mesh simultaneously, toothholder 5 and planet wheel 3 mesh simultaneously to the right with fixedly, just in time be positioned at the circular groove place of ring gear 13 with soldered tooth on planet carrier 4 this moment, planet carrier 4 is fixed on right output shaft 7, drive right output shaft 7 rotations, driving gear 6 is fixed on right output shaft 7 and with third wheel 8 and meshes, third wheel 7 meshes with free gear 9 simultaneously, free gear 9 empty sets are on left output shaft 15, can rotate freely on left output shaft 15, toothholder 11 is fixed on left output shaft 15, sliding gear collar 10 can horizontally slip on toothholder 11, in the time of left, left output shaft 15 disconnects with free gear 9, left output shaft 15 and free gear 9 combinations in the time of to the right.
2, when ring gear 13 slide left with duplicate gear 2 combinations, sliding gear collar 9 slides left when separating with free gear 8, be decomposed into two-part under the effect of power at planetary mechanism of input shaft 1 input, a part drives right output shaft 5 work through planet carrier 4, another part drives left output shaft 14 work through ring gear 12, duplicate gear 2 and driven gear 13, mechanism needs the Random assignment outputting power by the two ends, left and right, this mechanism works under 4 wheel driven, differential state, and the speed of a motor vehicle is minimum (referring to Fig. 1) also; When sliding gear collar 9 slides to the right when engaging with free gear 8, mechanism is by the fixed speed ratio of design in advance two ends outputting power to the left and right, and this mechanism works under 4 wheel driven, non-differential and lower-speed state.
3, when sliding, ring gear 13 engages (the circular groove place that this moment and the soldered tooth on planet carrier 4 just in time are positioned at ring gear 13) to the right with fixing toothholder 5, sliding gear collar 9 slides left when separating with free gear 8, power through input shaft 1 input drives right output shaft 5 work by planet carrier 4 after planetary mechanism slows down, mechanism is output shaft outputting power left not, and this mechanism drives two, (referring to Fig. 2) works under the middling speed state; When sliding gear collar 9 slides to the right when engaging with free gear 8, mechanism is by the fixed speed ratio of design in advance two ends outputting power to the left and right, and this mechanism works under 4 wheel driven, non-differential and middling speed state.
4, when being positioned at the neutral position, ring gear 13 engages with gear ring support 4, sliding gear collar 9 slides left when separating with free gear 8, planetary mechanism is locked, power through input shaft 1 input directly drives right output shaft 5 work via planet carrier 4, mechanism not left output shaft distribute outputting power, this mechanism drives two, work under fast state; When sliding gear collar 9 slides to the right when engaging with free gear 8, mechanism is by the fixed speed ratio of design in advance two ends outputting power to the left and right, this mechanism work under 4 wheel driven, non-differential and fast state (referring to Fig. 3).
5, according to cost and different job requirements, this mechanism can only keep differential and middling speed state, differential and fast state or middling speed and fast state: when only keeping differential and middling speed state, gear ring support 4 is cancelled soldered tooth, and ring gear 13 is also cancelled circular groove (referring to Fig. 4) simultaneously; When only keeping differential and fast state, cancel fixedly toothholder 5, ring gear 13 is also cancelled circular groove (referring to Fig. 5) simultaneously; When only keeping middling speed and fast state, cancel duplicate gear 2 and driven gear 13, fixedly toothholder 5 is fixed on the left side, and ring gear 13 is also cancelled circular groove (referring to Fig. 6) simultaneously.
6, in order to alleviate the heavy wear of front and back wheels under the non-differential state of 4 wheel driven, free wheel device 15 (referring to Fig. 7) can also be installed between driving gear 6 and right output shaft 7, have a mind to make the actuating speed of rear drive sprocket a little more than the actuating speed of front driving wheel when the design velocity ratio, like this under the effect of free wheel device 15, when normally travelling, front driving wheel is in driven state all the time, only have after trackslipping to a certain degree appears in rear drive sprocket, front driving wheel just plays the driving effect.
When 7, using, as required, this mechanism can separate with ransaxle, also can link together with ransaxle, and when this mechanism and ransaxle linked together, right output shaft 5 also can be made into the drive bevel gear of ransaxle one (referring to Fig. 8).
8, when this mechanism is used for tractor, multifunctional chassis or multi-purpose vehicle(MPV) etc. with the motor vehicle of pto＝power take-off, third wheel 8 can increase soldered tooth, empty set is on pto＝power take-off 17, also be equipped with toothholder 18 and sliding gear collar 19 on pto＝power take-off 17 this moment, sliding gear collar 19 can move left and right on toothholder 18, moving to right engages with soldered tooth on third wheel 8, moves to left and third wheel 8 disconnects.In the situation that so forwardly power output gear is thrown off, sliding gear collar 19 moves to right, the soldered tooth of itself and third wheel 8 is engaged, can obtain the power output shaft speed that changes with the speed of a motor vehicle, further expanded the speed range (referring to Fig. 9) of pto＝power take-off.
