A combustion engine (1) is installed on the frame. It drives the following
components:
•
Hydraulic pump (6) for the travel drive of the wheels
•
Mechanically shiftable auxiliary drive (power take-off shaft) (5)
The hydraulic pump (6) provides for the circulation of hydraulic oil. The system is
supplied with hydraulic oil by a central oil tank (3).
Each of the four wheels is individually supplied with hydraulic oil. This takes place
via the hydraulic valves (7). Therefore it is possible to drive the wheels with
different speeds and directions of rotation. This ensures very good
manoeuvrability. Depending on its configuration, the one-axle host vehicle can be
turned around its central high axis on the spot.
The crankshaft (4) is used for driving the hydraulic pump (6) and the power take-off
shaft (5). The power take-off shaft can be shifted manually via the operating unit
(2) and makes it possible that the attachment connected to the change fixture (9)
can be switched on or off. The attachments can vary. The one-axle host vehicle is
controlled via the operating unit (2). The one-axle host vehicle is parked without
attachment using the parking support (8).
