Valve Block
Valve Block: The valve block is an electrically controlled hydraulic distribution assembly and is located behind the right front wheel housing panel (at the base of the A-pillar).
Valve Block Functions
- Distribution of hydraulic fluid flow to the oscillating motors: The pressure at the front axle oscillating motor is greater than or equal to the pressure at the rear axle oscillating motor.
- Measuring the actual pressure of the high pressure hydraulic fluid: There is a pressure sensor for both the front and rear axle oscillating motor hydraulic circuits on the valve block.
- Fast and precise regulation via the pressure control valves: Introduced pressure changes as a result of uneven roads are passively regulated to reduce noise as much as possible.
- Adjustment of the volume flow direction (left hand/right hand twist) via a directional valve: The directional valve position is detected by a selector position recognition sensor (SSE).
- Switch to Failsafe mode in the event of power supply failure or a fault is detected in the system: The front axle oscillating motor hydraulic circuit is closed off and hydraulic flow is diverted to the reservoir. The check valves will open to allow the hydraulic fluid to be drawn from the reservoir. The rear axle oscillating motor hydraulic circuit is also deactivated and hydraulic flow is diverted to the reservoir.
- Limiting the system pressure in the event of a fault: The Failsafe valve causes the circuit to close when de-energized, decreasing the system pressure (circulating).
