Good effect of the present utility model is easy for installation, reliable performance, and bearing capacity is large, and output form is many, is convenient to the general arrangement of car load, can meet the multiple behaviour in service of medium-heavy automobile.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further: as shown in Figure 1, power take-off assembly is put at the end, by power taking axle input gear 1, power take-off input gear axle 2, power take-off output gear 3, power take-off output shaft 4, power take-off toothholder 5, power take-off gear shift tooth cover 6, shift fork 7, declutch shift shaft 8, air input joint 9, indicator cock 10, return spring 11, bead 12, bead fastening base 13 forms, power take-off is directly installed on bottom speed changer, power take-off input gear 1 engages power taking with speed changer main tank countershaft-gear, it is characterized in that: power take-off input gear axle 2 is arranged in the top in power take-off housing, power take-off output shaft 4 is arranged in the middle part in power take-off housing, power take-off output shaft 4 is hollow shaft structure, inner spline groove is provided with in power take-off output shaft 4, power take-off output gear 3 is fixedly connected on the power take-off toothholder 5 on power take-off output shaft 4, power taking axle input gear 1 on power take-off input gear axle 2 engages with power take-off output gear 3, it is spacing by bead fastening base 13 that bead 12 is positioned at power take-off housing rear end, bead 12 front end is provided with external splines, bead 12 front end is inserted in the inner spline groove of power take-off output shaft 4, power take-off output shaft 4 axle head adopts end cover 14 to press-fit sealing, power take-off toothholder 5 is provided with external splines, power take-off gear shift tooth cover 6 by the spline inside it and power take-off toothholder 5 external splines engagement sleeves on power take-off toothholder 5, fork slot is had outside power take-off gear shift tooth cover 6, declutch shift shaft 8 is arranged in the below in power take-off housing, declutch shift shaft 8 front end connects air input joint 9, declutch shift shaft 8 cover has return spring, shift fork 7 on declutch shift shaft 8 inserts in the fork slot on power take-off gear shift tooth cover 6, power take-off housing bottom has indicator cock 10 to be connected with shift fork 8.
Power take-off output shaft 4 is hollow shaft, inside establishes spline, by this inner spline groove and the output based version realizing power take-off splined, also can be connected with the bead 12 being provided with external splines by inner spline groove, realizes the output based version of power take-off bead.
Concrete power transmission route is: through gears meshing, power is passed to power take-off output gear 2 by power take-off input gear 1 by speed changer main tank countershaft-gear, then by the connection of power take-off gear shift tooth cover 6, by transmission of power to power take-off output shaft 4, then exported by power take-off output shaft 4 spline, or power take-off output shaft 4 passes to bead 12 and outputs power.
