Design
Fig. 86
The SES system (SES = Strautmann Electronic Steering) mainly consists of:
the control set (1),
the steering computer (2),
the angle sensors (3) at the drawbar and the axle to determine the required steering angle,
the speed sensors (4),
the hydraulic components (5),
the pressure switch (6).
Via 2 angle sensors and 2 speed sensors, the SES system electronically registers the required
steering angle which is adjusted to the speed, and transforms the required steering angle into an
electrical signal. The steering computer transmits the information to an electrically actuated hydraulic
valve and thus controls the steering cylinders of the steerable axles. The pressure switch registers the
pressure in the hydraulic system. If the hydraulic pressure is below 25 bar, the SES system is not
ready for operation. The pressure switch reacts as soon as the hydraulic pressure falls below 25 bar
and activates the follow-up steering system.
The SES system:
controls depending on the speed,
informs about malfunctions of the steering system via acoustic and visual warning messages on
the control set,
