Electric Power Steering – Maintenance-free power-on-demand steering for the future of vehicle control
Electric Power Steering (EPS) from Knorr-Bremse sets new standards for performance and efficiency in steering. The completely redesigned system architecture of electrically supported steering combines proven effective principles with the latest technology. By doing so, EPS significantly improves energy efficiency while reducing overall costs. It increases steering comfort, while at the same time paving the way to electromobility and autonomous driving.
Compared to most hydraulic steering systems available on the market, EPS from Knorr-Bremse works on a power-on-demand basis: It only consumes power when the steering angle is changed. A special solution patented by Knorr-Bremse ensures that the steering system still activates without a delay. The heart of the system consists of a motor and a pump which are both fully integrated into the steering unit and controlled by an ECU.

Modular, compact and maintenance-free
The EPS system has a modular structure. Depending on the vehicle application, the individual components can be assembled flexibly and adjusted to different installation areas and vehicle classes.
EPS steering is designed as a highly integrated plug-and-play system for vehicle manufacturers. It is delivered pre-configured to the assembly line. Once it is connected to the power supply of the vehicle, the system is ready for use and is maintenance-free from there throughout the entire life cycle. There is no need to re-lubricate it, replace wear parts or hydraulic oil, which reduces overall costs and improves sustainability.
Power for two
EPS can achieve steering forces of up to 8.5 kNm in regular configurations. In vehicle configurations with especially high axle loads that require two driven front axles, EPS from Knorr-Bremse allows for the connection of an auxiliary hydraulic cylinder. This is implemented using a fully-integrated motor and pump that are controlled by an ECU. In this way, the EPS also delivers higher forces for adjusting the steering angle.
Key benefits:
