Selective pump and valve control rinses hydraulic suspension lines while preserving switchable roll and pitch stiffness with better packaging.
- Electric Motor Torque Control for Fast Hydraulic Pump Response
Directly mapping actuator load pressure to motor torque cuts PLC and CAN latency, improving hydraulic response and energy use.
- Electric Motor Speed Control for Hydraulic Pump Noise Cancellation
Periodic motor speed modulation counteracts pump pressure pulsation in vehicle hydraulics, cutting noise without redesigning the system.
- Electronic Pump Angle Adjustment for Precise Flow and Volume Control
A linear actuator pivots the motor-pump angle to replace manual displacement setting and deliver steadier flow with accurate dispense volumes.
- Integrated Servo Unit Layout for Axial Piston Displacement Control
A housing-integrated servo cylinder tilts the swivel element to vary displacement volume without enlarging the axial piston unit.
