Valve block

The following valves are integrated in the valve block:

• Pressure valves of the front and rear axle
• Directional control valve
• Safety valve
• Non-return valves

The valve block is located in the right front wheel arch near the A pillar. It performs the following tasks:

Two pressure control valves (one each for the front and rear axle) split the oil flow. The oil flow then leads to the hydraulic motors. The pressure at the front-axle hydraulic motor is greater than or equal to the pressure at the rear-suspension hydraulic motor.

Measuring the actual pressures of the high-pressure oil: There is a pressure sensor at each of the valve-block outlets for the front and rear axle hydraulic motors.

The direction of rotation of the two hydraulic motors is set by a shared direction valve. The position of the direction valve is detected and monitored by means of a switch position sensor.

In the following cases, the front-suspension hydraulic motor is sealed and locked. Can be drawn in from the hydraulic line via the shut-off valves.

1. Transition into the fail-safe state
2. Detected malfunction of the system
3. Failure of the power supply

Can be drawn in from the hydraulic line via the shut-off valves.
