Steering should be hardly noticed by the driver. At the same time, it should be absolutely reliable, easy to handle, and fuel efficient in operation.
Thanks to a modular system with highly versatile components, our power steering pumps for medium- to heavy-duty commercial vehicles are designed to meet a wide range of requirements: a reliable oil supply to the steering system, high power density at a low weight, improved system efficiency, and lower fuel consumption. As a result, our products also play a key role in helping to comply with increasingly strict CO2 guidelines.
Thanks to the flexible design, our power steering pumps can be combined with other types of pumps as required and additional modular functions can be integrated. The wide range and the long-term thinking that goes into our solutions are just one reason nearly all major automotive manufacturers count on our power steering pumps.
Reliable steering power at a reduced energy consumption and a noise level that is the best in class. In order to meet local market requirements and the global challenges of our customers, our electrohydraulic power steering pump for medium- to heavy-duty commercial vehicles combines one or several motors with integrated power electronics and state-of-the-art vane pump technology.
Optimum system pressure, highly precise power assistance, and power consumption lower than with conventional power steering pumps: Varioserv® variable displacement pumps consistently run efficiently and at the same time help to reduce fuel consumption and CO2 emissions. By using individual additional modular functions, further types of pumps can be integrated to open up further areas of application.
Our radial piston pumps maintain the steerability of medium- to heavy-duty commercial vehicles if the engine should fail. Totally automatic, absolutely reliable. Besides being used as emergency steering pumps, our radial piston pumps are allrounders for other special applications for hydraulic movements.
