6 6 Details of hydrostatic fan drives Optimize the energy consumption of your diesel engine by fitting a electronically actuated variable displacement, pressure control pump for a hydrostatic fan drive. Apart from fuel economy, this solution reduces noise and exhaust emissions as well. The complete subassembly is compact and easy to integrate. Other advantages include, speed of operation de-coupled from engine speed, and flexibility in cooling system layout. Variable displacement pump provides required cooling power, irrespective of diesel engine speed Axial piston motor combines its eicient output with that of the axial piston pump. Suitable for applications requiring a high considerable pressure levels. Gear motor option available f f Reservoir exceptional ratio between max. flow rate/tank volume without impacting on oil quality. Low-weight manufactured in accordance with DIN EN Patented design. Controller (PLC) used in automotive applications (buses, HGVs). Up to 5 % fuel reduction. Application specific control and diagnostics. Temperature, pressure and contamination sensors.

7 7 Hydrostatic auxiliary drives Utilizing the advantages of hydraulics to the max: the easy expandability, combined with open and closed-loop controllability of hydraulic power, increases the overall system eiciency by including additional auxiliary drives. Whether fan, compressor or alternator drive: with the broadest spectrum of hydraulic pumps and motors Rexroth provides virtually unlimited possibilities for integrating the right power at the right location. The components, which are finely scalable both in function and power, fit perfectly in diesel-powered rail vehicles. Additional functions, such as overpressure protection, coupling and uncoupling of generators and bypass closed-loop control all help to increase safety and reduce energy consumption. Such tasks typically use components designed for mobile applications. Advances in precision manufacturing, with respect to materials as well as additional hydraulic and electronic closed-loop controls, lengthen maintenance intervals, and increase flexibility in operation. Rexroth specialists can provide advice for optimum design of components and their integration into the master engine control. This enables the auxiliary drives to keep the rail vehicle moving hydraulic reliably and consistently.
