Compared with prior art, the utility model has following useful technique effect:
The utility model is a preposition power take-off of triple axle aiming at two jack shaft series of transmission and match, it is arranged between speed changer and clutch, power take-off speed ratio is reasonable, meet the requirement of most of refitted car, widen the scope of preposition power take-off output torque, solve the problem that market does not have high pulling torque to export.Because power take-off is arranged between clutch and speed changer, whether power take-off works does not affect shift of transmission performance.Require so large output torque, this design is under the prerequisite meeting the strength of gear teeth and speed ratio requirement, by selecting suitable material and the gear-driven speed ratio of reasonable distribution two-stage and optimal design teeth portion parameter, to reach the object of adjusting gear size, calculate finally by CAE and check power take-off intensity.Output torque is at 2100Nm, and rotation direction is identical with motor, meets actual demand.
Further, piston fork shaft is stretched out and retraction by pneumatic control, precise control, convenient operation.
Further, the teeth portion parameter of four gears is all identical, and meeting the speed ratio of this power take-off own is 1, and compares rearmounted power take-off, and it exports speed ratio not by the change of Transmission gear, can not bring adverse effect to speed changer entirety gearshift performance.
Further, in order to ensure that this power take-off normally uses, we devise power take-off itself with selflubricating and cooling structure.Ensure that nominal situation when power take-off works under high pulling torque.

Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail, described in be to explanation of the present utility model instead of restriction.
As shown in Figure 1, the preposition power take-off of this kind of triple axle of the utility model, comprises power take-off housing 1, is disposed with input shaft 2, two axle 7 and output gear shaft 5 in power take-off housing 1 from lower to upper; The side plate 3 that input shaft 2 left end passes power take-off housing 1 is connected with power source, and on input shaft 2 right-hand member, key is connected with input gear 10; On two axle 7 left ends, key connects two shaftgears 8, sheathed two axle shifting slide gears 9; On output gear shaft 5 left end, key connects output shaft gear 6, and right-hand member passes power take-off housing 1 and is connected with flange plate 4.Input gear 10 engages with two axle shifting slide gear 9 selectivity, and two shaftgears 8 often engage with output shaft gear 6.Piston fork shaft 12 is provided with between two axles 7 and output gear shaft 5, piston fork shaft 12 left end arranges shift fork 13 downwards, shift fork 13 is stirred two axle shifting slide gears 9 and is moved horizontally, the right-hand member of piston fork shaft 12 passes power take-off housing 1 and is located in piston cavity, piston cavity is fixedly located on power take-off housing 1, and and compressed air communication.
Also comprise lubrication and cooling system, lubrication system comprises the gear pump 14 be arranged on power take-off housing 1, gear pump 14 is communicated with the oil outlet tube of power take-off housing 1, and is communicated with the filler opening at power take-off housing 1 top, is lubricated by lubricant oil to be pumped into top by oil pipe filler opening from bottom.Cooling system comprises oil cooling service pipe welding assembly 11, is transported to after outside cools by the oil bottom power take-off housing 1 and is delivered into enclosure interior again.
During real work, as shown in Figure 1, this preposition power take-off matches with two jack shaft series of transmission.When needs power take-off works, disconnect the pressurized air for high pressure (pressure is 0.7 ~ 0.8MPa) on the right side of piston fork shaft 12 upper piston, be now under normal pressure (pressure is 0.41 ~ 0.44MPa) effect on the left of piston, drive two axle shifting slide gears 9 to move right by shift fork 13, power take-off two axle 7 is engaged with the input gear 10 on power take-off input shaft 2.Then power is passed to output gear shaft 5 by two shaftgears 8 through output shaft gear 6, is finally exported by output flange 4.
When not needing power take-off to work, only need connect the pressurized air for high pressure (pressure is 0.7 ~ 0.8MPa) on the right side of piston fork shaft 12 upper piston, under the effect of piston pressure at both sides difference, piston fork shaft 12 and shift fork 13 drive two axle shifting slide gears 9 to return neutral gear position, realize power take-off and pluck gear.
Oil bottom power take-off operationally, can be transported to the top gear of lubricating upper and bearing from top to bottom by oil pipe by gear pump 14 by power take-off; Cooled by oil cooling service pipe welding assembly 11 pairs of power take-off lubricant oil, so all ensure that nominal situation when power take-off works under high pulling torque.
