TRANSMISSION
The multi-speed reversing transmission in countershaft design is power shiftable by hydrauli-cally actuated
multi-disk clutches.
All gears are constantly meshing and carried on antifriction bearings.
The gear wheels, bearings and clutches are cooled and lubricated with oil.
The 6-speed reversing transmission is equipped with 6 multi-disk clutches. (Figure example)
At the shifting, the actual plate pack is compressed by a piston, movable in
axial direction, which is pressurized with pressure oil.
A compression spring takes over the pushing back of the piston, thus the release of the plate pack.
As to the layout of the transmission as well as the speciļ¬cations of the closed clutches in the single
speeds.
See in chapter 2.3 Disassembly & Assembly for other clutches.
