OPERATION OF TRANSMISSION
(1)
Gearbox diagram
The multi-speed reversing transmission in counter shaft design is power shiftable by hydraulically
actuated multi-disk clutches.
All gears are constantly meshing and carried on anti-friction bearings.
The gear wheels, bearings and clutches are cooled and lubricated with oil.
The 3-speed reversing transmission is equipped with 5 multi-disk clutches.
At the shifting, the actual plate pack is compressed by a piston, movable in axial direction, which is
pressurized by pressure oil.
A compression spring takes over the pushing bask of the piston, thus the release of the plate
pack. As to the layout of the transmission as well as the specifications of the closed clutches in
the single speeds.
