- 2 Steering hydraulics
- System concept
- Fully hydraulic steering (Emergency steering)
- Orbitrol axle = Floating axle (1), the rigid axle (2) is tracked by electro-hydraulic means
- Orbitrol axle = Rigid axle (2), the floating axle (1) is tracked by electro-hydraulic means
- The floating axle (1) and the rigid axle (2) are steered electro- hydraulically - the Orbitrol steering circuit is closed.
- Steering valve VI
- 3 Working hydraulics
