Power takeoff clutch pedal is unclamped, engine power reaches power takeoff input shaft 1, the output gear band of input shaft 1 Dynamic jackshaft high gear gear 4 rotates, and jackshaft high gear gear 4 drives jackshaft 3 and jackshaft low gear gear 5 to rotate synchronously, in Between axis low gear gear 5 drive output shaft low gear gear 9 rotate, output shaft low gear gear 9 drive gearshift sliding sleeve 8 rotate, shift slide Set 8 drives output shaft 6 to rotate, and output shaft 6 drives ring flange rotation, finally by ring flange output power.
Jackshaft high gear gear 4 drives output shaft high gear gear 7 to rotate simultaneously, due to output shaft high gear gear 7 and output Axis 6 is connected by needle bearing, so not output torque.
Two, power takeoff is linked into high gear
It when power takeoff works, steps on power takeoff clutch pedal to clutch and is completely separated, operate power takeoff gear lever, take Power device hangs high gear.Gear shifting pulling head drives shift fork 10 and shift fork axle 11 to move to left, and shift fork drives gearshift sliding sleeve 8 to move to left, gearshift sliding sleeve 8 with Output shaft high gear gear 7 is connected by spline;
Power takeoff clutch pedal is unclamped, engine power reaches power takeoff input shaft 1, the output gear band of input shaft 1 Dynamic jackshaft high gear gear 4 rotates, and jackshaft high gear gear 4 drives output shaft high gear gear 7 to rotate, output shaft high gear gear 7 Gearshift sliding sleeve 8 is driven to rotate, gearshift sliding sleeve 8 drives output shaft 6 to rotate, and output shaft 6 drives ring flange rotation, finally by flange Disk output power.
Jackshaft low gear gear 5 drives output shaft low gear gear 9 to rotate simultaneously, due to output shaft low gear gear 9 and output Axis 6 is connected by needle bearing, so not output torque.
Three, power takeoff is linked into neutral gear
When power takeoff being needed to stop working, power takeoff clutch pedal is stepped on, operates power takeoff gear lever, power takeoff is hung empty Gear, gearshift sliding sleeve return to middle position, and gearshift sliding sleeve 8 is separated with output shaft high gear gear 7 or output shaft low gear gear 9, power It interrupts, power takeoff stops working.
The two gear Full-power takeoff by three horizontally disposed parallel axes, realize by two-stage gear drive.Wherein, input shaft For hollow gear shaft, empty set is outside transmission input shaft;Jackshaft is disposed with low gear gear and high gear gear, and wherein jackshaft is high Gear gear is often engaged with input shaft axis tooth;Output shaft high gear gear, gearshift sliding sleeve, defeated is disposed on output shaft from left to right Shaft low gear gear is provided with needle bearing between high and low gear gear and output shaft, and gearshift sliding sleeve moves left and right realization block selecting, Then realize that two gears of power takeoff export by output flange.
Compared with prior art, the utility model has technical effect beneficial below:
1, the input shaft of power takeoff is hollow gear shaft, is connected respectively by different clutch splines from transmission input shaft To engine flywheel disk, the driving power taking and total power power taking of power takeoff are realized.
2, power takeoff can realize two kinds of output revolving speeds and torque according to operating condition.High and low gear is disposed on power takeoff output shaft Gear and gearshift sliding sleeve are disposed with needle bearing between high and low gear gear and output shaft, and sliding sleeve is connect with output shaft spline, dial Fork stirs height, the sky, low gear of sliding sleeve control power takeoff, realizes gear switching.
3, three axis of power takeoff are horizontally disposed, and power takeoff is independent sealed, and lubrication of splashing, gear, bearing lubrication are reliable.
4, the internal spline of the external splines and output gear of the gearshift sliding sleeve on output shaft uses back taper toothing spline engagement, With self-locking function, reduces and fall danger of keeping out the wind.
The above content is only to illustrate the technical idea of the utility model, and the protection model of the utility model cannot be limited with this Enclose, it is all according to the utility model proposes technical idea, any changes made on the basis of the technical scheme each falls within this reality Within protection scope with novel claims.
