Description of the drawings
Fig. 1 is the schematic diagram of the utility model；
Fig. 2 is the background technology schematic diagram of the utility model.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1, horsepower gearbox transmission device of tractor in the utility model, including be socketed on power input shaft
Duplicate gear 1, be socketed in duplicate gear gear wheel side first bearing 2, be socketed in the pinion gear side of duplicate gear
Second bearing 3, thrust ring 4, thrust ring baffle ring 5, middle-grade driving gear 6, middle-grade engagement seats 7, middle-grade engaging sleeve 8, engagement seats
Baffle ring 9, spline housing 10 and middle-grade driven gear component 11；
It is socketed thrust ring 4 on the axis body of duplicate gear 1 between first bearing 2 and second bearing 3 successively from left to right, stops
Throw-out collar baffle ring 5, middle-grade driving gear 6, middle-grade engagement seats 7 and engagement seats baffle ring 9；The inner wall of middle-grade driving gear 6 is without interior
Gear, middle-grade driving gear 6 coordinate with 1 transition of duplicate gear, and middle-grade driving gear 6 is major diameter at a stairstepping, one end
Driving cog 61, the other end is the clutch tooth 62 of minor diameter, and clutch tooth 62 matches with the internal gear of middle-grade engaging sleeve；Middle-grade engages
Seat 7 is engaged by internal gear with duplicate gear 1, and the external gear of middle-grade engagement seats 7 is matched with the internal gear of middle-grade engaging sleeve；Middle-grade
Engaging sleeve is axially moved between the external gear of middle-grade engagement seats 7 and the clutch tooth 62 of middle-grade driving gear 6；10 sets of spline housing
It is connected on the power output shaft between two axis spline housings 10 and low-grade driven gear, the internal spline and power output of spline housing 10
Axis external splines engages；Middle-grade driven gear component 11 is one that middle-grade driven gear 111 and the passive engaging sleeve 112 of middle-grade form
Axial one end of a global facility, middle-grade driven gear component 11 is middle-grade driven gear 111, middle-grade driven gear component 11
The axial other end is the passive engaging sleeve of middle-grade 112；The internal spline of middle-grade driven gear component 11 respectively with the outer flower of spline housing 10
