Characteristically fully hydraulic steering systems do not rely on a mechanical link between the steering wheel and the wheels on the ground. This is a major advantage for the vehicle designer and is probably one of the main drivers for the widespread success of fully hydraulic steering systems. However, the absence of a mechanical link leads to a loss of positional relationship between the steering wheel and the wheels on the ground. The relationship between the rotational position of the steering wheel and the driving direction of the vehicle may vary. This is a traditional short coming of fully hydraulic steering systems, and is well understood in the industry. Danfoss EFU represents a means to establish a fixed relationship between rotational position of the steering wheel and the driving direction of the vehicle, with fully hydraulic steering systems. Danfoss EFU is designed to provide very high positional accuracy while at the same time maintaining smooth and unobtrusive operation with no unwanted side effects for the driver. Danfoss EFU is patented technology.
Features Danfoss EFU provides a number of advantages:
Keeps steering wheel aligned with tires ‒ Improved driver comfort and efficiency ‒ Improved intuitive steering control ‒ Knob stays in same position ‒ Steering wheel logo stays correct ‒ Allows special steering wheel design
Smooth operation ‒ Seamless and transparent for the driver ‒ No comfort trade-offs
Fast and accurate ‒ Generous compensation capacity means fast and accurate performance ‒ No safety trade-offs
