Hydrostatic drive with inching
The diesel engine permanently drives a hydraulic pump (variable
displacement pump), the oil flow of which is sent to a hydraulic motor
flanged on the transfer gearbox. The output of the hydraulic motor is
passed on via the transfer case (flanged to the front axle) further via the
universal joint shaft connection to the rear axle so that a permanent all-
wheel drive exists.
Work hydraulics and 4 wheel steering
A gear pump (flanged on the variable displacement pump of the drive)
supplies the work hydraulics and, via a priority valve, also the hydrostatic
steering.
The oil flow of the pump depends on the diesel engine speed.
When the machine is in operation, the entire diesel engine output can be
transmitted to the gear pump for the work hydraulics and steering. This is
made possible by a so-called inching valve that responds as soon as the
brake/inching pedal is used, reducing or cutting off power input of the
drive.
Therefore, engine output is fully available for the loader unit by pressing
the accelerator pedal and the brake/inching pedal at the same time.
Cooling system
There is a combined water-hydraulic oil cooler, intercooler and fuel cooler
in the engine compartment.
The hydraulic oil temperature as well as the cooling temperature of the
diesel engine are indicated via the control lamps in the display instrument
(dashboard).
