Accompanying drawing explanation
Fig. 1 is sectional structure chart of the present utility model.
Fig. 2 is external structure of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further: as Fig. 1, shown in 2, rearmounted power takeoff assembly, by force taking bushing pipe 1, circlip for shaft 2, transition gusset piece 3, power takeoff assembly 4, power takeoff input shaft 5, power takeoff input gear 6, power takeoff output shaft 7, power takeoff output shaft gear 8, bead fastening base 9, hex bolt 10, bead 11, power takeoff gear shift tooth cover 12, inlet suction port 13, declutch shift shaft 14, shift fork 15, pull back spring 16, indicator cock 17 forms, it is characterized in that: transition gusset piece 3 is fixed on change-speed box rear end, power takeoff assembly 4 is fixed on transition gusset piece 3, power takeoff input shaft 5 is positioned at power takeoff housing medium position, power takeoff input shaft 5 is connected with change-speed box main tank tween drive shaft from the front end that power takeoff housing stretches out by force taking bushing pipe 1, circlip for shaft 2 is had between force taking bushing pipe 1 and power takeoff input shaft 5, the back-end location of power takeoff input shaft 5 is with spline toothholder, input shaft spline toothholder is provided with male splines, with inner spline groove inside power takeoff gear shift tooth cover 12, power takeoff gear shift tooth cover 12 to be coordinated with male splines by inner spline groove and is fixedly connected on input shaft spline toothholder, power takeoff input shaft 5 stage casing needle bearing is fixedly connected with power takeoff input gear 6, declutch shift shaft 14 is positioned at power takeoff housing top, on declutch shift shaft 14, cover has pull back spring 16, inlet suction port 13 on power takeoff housing is connected with declutch shift shaft 14 one end in power takeoff housing, control fork 15 is fixedly connected on declutch shift shaft 14, with fork slot outside power takeoff gear shift tooth cover 12, selector fork 15 coordinates with fork slot, power takeoff output shaft 7 is positioned at the below of power takeoff enclosure interior, power takeoff output shaft gear 8 on power takeoff output shaft 7 engages with power takeoff input gear 6, power takeoff output shaft 7 rear end is connected with bead fastening base 9, bead 11 is fixedly connected on bead fastening base 9 by hex bolt 10, bead 11 is positioned at power takeoff housing rear end, indicator cock 17 is arranged in above power takeoff housing and is connected with the selector fork 15 of power takeoff enclosure interior.
Concrete power transmission route is; Power is transferred to power takeoff input shaft 5 by force taking bushing pipe 1 by the spline of change-speed box main tank tween drive shaft, then by power takeoff gear shift tooth cover 12 connection by transmission of power to power takeoff input gear 6, then power takeoff input gear 6 by transmission of power to power takeoff output shaft 7, then exported by power takeoff output shaft 7 spline, or power takeoff output shaft 7 passes to bead 11 and outputs power.
Concrete mode is: the air passing into 0.4-0.5MPa at power takeoff inlet suction port 13, and air push declutch shift shaft 14 moves, and declutch shift shaft 14 drives shift fork 15, shift fork 15 promotes power takeoff gear shift tooth cover 12, thus making tooth overlap combination, transmission of power starts, power takeoff work.When not needing power takeoff to work, cutting off the air of admission port, by pull back spring 16, power takeoff transmission of power being interrupted.
