Electro Hydraulic Power Steering – Commercial Vehicles
The Concentric EHS (Electro Hydraulic power Steering pump) replaces the conventional IC engine-driven pump for hybrid, fuel cells, or pure electric trucks and buses.
The EHS is composed of an air-cooled BLDC electrical motor, including a controller, showing a maximum output power of 7 kW assembled with a hydraulic pump.
The EHS is covering a flow demand from 12 l/min at 280 bar to 80 l/min at low pressure.
Concentric’s EHS offers system power savings through its automatic de-rating rotation speed following pressure and speed control capability via CAN Bus communications.
EHS Self Speed Torque Control can also be implemented on demand.
The base components for the electro-hydraulic steering unit embody an advanced development of Concentric’s current BLDC electric motor pump technology, which has established a well-founded reputation for reliability and build quality in steering applications around the world, both On and Off-highway.
The new EHS product range allows CAN Bus communication between the motor and the vehicle’s main control system to control pressure and flow on demand. This significantly reduces system losses compared to traditional mechanical drive systems, ensuring optimum performance of the steering system.
