Dana TM4 Electro Hydraulic Power Steering (EHPS) systems combine an IPM motor, a low noise gear pump and a Schwarzmüller Inverter. This robust, reliable and safe system range provides oil flow for assisted steering applications allowing a 30 - 50% energy saving by “power on demand” for a fast project turn-around and an adjustable steering performance. It is perfectly adapted for any bus applications while allowing a more modular design.
Provide oil flow for assist steering applications by a range of systems:
- Nominal flow system range: 16 - 25 I/min
- Peak pressure: 195 bar
- Powered by std. 24Vdc battery (Board net)
- Communication with Vehicle Controller via CAN J1939 (CAN Open on request))
- Fault tolerant Fall-back operation mode at system failures
- Low noise pump technology ≤ 55dBA (1500rpm, 195bar)
- Power is independent of engine speed
- Up to 4% fuel / energy savings on vehicle
- Reduced installation costs vs. hydraulic piping
- Fast project turn-around with ready-to-start EHPS SW
- Customized control features
- Highly efficient electro-hydraulic system
