The Radial Dynamics HV Power Steering Pump System provides the ultimate hydraulic power steering option for electric and hybrid electric vehicles, offering unmatched power density and duty cycle capability while minimizing energy waste and extending driving range through the use of intelligent power-on-demand controls.
Provide electro-hydraulic fluid power to any traditional power steering equipment including steering boxes, rack and pinions, and full hydro orbital valves. Auxiliary hydraulic functions such as rear steer and hydraulic winches are also supported through the use of optional switched inputs to command higher fixed flow rates as needed.
This system requires a high voltage (200-800VDC) power source since the electro-hydraulic pump operates direct from the bus voltage of an electric vehicle's battery pack.
Kit includes the high voltage electro-hydraulic pump unit, steering column torque sensor (optional), electrical controls hardware, and wiring only. Reservoirs, hydraulic control valves, filters, and other plumbing hardware sold separately.
