Described power input shaft 1 can be motor output shaft or other power input shaft, and described elastic element 25 is a stage clip.
According to the planetary reduction gear motion theory as can be known, when ring gear is a driving link, during planet carrier output, planet carrier, can realize four kinds of functions respectively when sun gear is in different conditions: (one) sun gear is fixedly the time, ring gear drives the planetary pinion commentaries on classics and drives planet carrier, planet carrier is retarded motion, and its reduction speed ratio is the ring gear number of teeth and the ratio of the sun gear number of teeth; (2) sun gear is movable, and when planet carrier followed sun gear locked simultaneously, ring gear drove planet wheel and sun gear one runs up (unitary rotation), and not slowing down this moment is motion in 1: 1; (3) sun gear is fixed, and when planet carrier followed sun gear locked simultaneously, planetary gear speed reducing mechanism can not rotate (braking state); (4) sun gear is movable, and when planet carrier followed sun gear not locked simultaneously, internal gear drove the planetary pinion commentaries on classics and also drives the sun gear commentaries on classics, and planet carrier does not have relative movement (idling conditions).
Working principle of the present invention is:
When 1, external hydraulic operating system made left oil duct A lead to the obstructed oil of high pressure oil, right oil duct B, left cylinder action backs down left platen 15 separated left clutch, and right clutch is located jointing state under the effect of elastic element 25.This moment, power input shaft 1 was fixed on the driving gear 9 on the planet carrier when rotating, do retarded motion under the drive of land 2, ring gear 7, planetary pinion 6 for sun gear is fixed, planet carrier is movable.
When 2, external hydraulic operating system made right oil duct B lead to the obstructed oil of high pressure oil, left oil duct A, right cylinder action backed down right platen 22 and makes that right clutch separates, the left clutch combination.This moment, sun gear and planet carrier were locked, and power input shaft 1 is fixed on the driving gear 9 on the planet carrier when rotating, make unitary rotation together with sun wheel shaft 19 under the drive of land 2, ring gear 7, planetary pinion 6, and driving gear 9 transfers motion in 1: 1 to by deceleration.
When 3, external hydraulic operating system made left oil duct A, B lead to high pressure oil simultaneously, left clutch and right clutch all were in separated state.This moment, sun gear and planet carrier all were movable, and when power input shaft 1 rotated, sun wheel shaft 19 was rotated under the drive of land 2, ring gear 7, planetary pinion 6, and the driving gear 9 that is fixed on the planet carrier is motionless, is " neutral gear " state.
When 4, external hydraulic operating system made the simultaneously obstructed oil of left oil duct A, B, left clutch and right clutch all entered jointing state under the effect respectively of stage clip 25 and left and right sides platen.Sun wheel shaft 19 is braked, and planet carrier and sun gear are by locked, and driving gear 9 can not rotate, and enters " stopping brake " state.
Above embodiment is more preferably embodiment a kind of of the present invention, the common variation that those skilled in the art carry out in the technical program scope and replace and should be included in protection scope of the present invention.
