Abstract

The invention relates to the field of agricultural engineering, in particular to drive axles of trailed transport and technological machines. The goal is to increase reliability. The drive of the trailer drive axle contains a gearbox 1, the drive shaft 2 of which is connected with the tractor's power take-off shaft, and the driven shaft 9 is the main drive of the drive axle. On the crown gears 13 and 14, additional gear rims 15 and 16 are installed, which are in constant engagement with gears J7 and 18 mounted on the shaft 19 of the hydraulic pump 20. There are coupling sleeve 21 and an actuator 23. The switching on and off and on Disconnection by means of connecting ml / ft 21 gears 17 and 18 to the shaft 19 of the hydraulic pump 20. At the same time, the control mechanism 22 connects the pressure line of the hydraulic pump 20 to the drain, thereby facilitating the gear shifting. 1 hp f-ly, 2 ill. and o C

Reissu Spruce Splash 29 Eolot of the Ikov type Sos-Ditslet natiopjjym mli-ttctral 30 Guide ™ Roposa 20 with a slip. Due to these reasons, the gear wheels 13 and 14 are disengaged, and no torque is transmitted to the drive axle.

Drive engagement. To engage the actuator, the stem 24 of the actuating mechanism 23 rotates the two-arm lever 25 relative to the hinge 26 to some extreme position. At the same time, on the one hand, one of the gears 17 or 18 is connected to the shaft 193 ac of the other side - the hydraulic pump 20 is gradually slowed down by locking the pressure line 30 with a valve of the spool type 29. As a result, it slows down; for example; the crown gear 14s and the gear ratio of the planetary row will be equal to the given. Torque through shaft 2, gear 3s gear 4, intermediate shaft 5s sun gear b, satellites 125 of the axis lOj drove 8 to the driven shaft 9 and then to the drive wheels of the trailer.

Gear shifting. When switching speeds, the rod 24 of the executing mechanism 23 rotates the double lever 1 to the other extreme. position. In this case, first, the pressure line 30 of the hydraulic pump 20 is connected with the drain of the 2E gold-Hi-acoBoro type hydraulic distributor. Consequently, despite the fact that the gear 18 is still connected to the shaft 19 of the hydraulic pump 20, the spreading of the hydraulic pump 20 occurs, and and the ring gear 13. The transmission of torque to the drive wheels is stopped. Next, the gear 18 is disconnected from the shaft 19 of the hydraulic pump 20. After this, as the soy is further moved, the zinc coupling 21 connects the gear 1 to the room 19 and decelerates. The m-ite wheel gear 13 is similar to the previous mode of operation.

Turn off the drive. To switch off the drive, it is necessary to set, by moving the stem 24, the actuator 23 and turning the lever 25 relative to the hinge 26, connect the 1st coupling 21 to the middle position. In this case, gears 17 and 8 are not connectors with shaft 9, but pedronable is retarted, as a result of which torque is not transmitted to the driving wheels.
