Krampe trailers with new steering system without drawbar sensor
Making work easier for their customers is the Krampe technicians' aim. To optimise the handling of large tippers and reduce the effort required for hitching, Krampe now relies on the steering system without drawbar sensor from ME Mobil Elektronik GmbH.
The electronic hydraulic steering system DynamicTrailerSteering System uses a system of sensors installed on the trailer to determine the driving situation of the tractor-trailer combination to optimise the driving behaviour. Several sensors of different measuring technologies are used simultaneously.
Two pulse generators, which measure the speed and direction of travel on one axle, send the data to a central steering computer. Another sensor supplies data on trailer movements.
With the help of an algorithm, the steering computer determines any missing values that are required to determine the articulation angle between the tractor and the trailer and the consequent steering movement of the trailer.
The steering system of the trailer is self-sufficient and only requires electronic and hydraulic supply from the tractor. This means that the required safety level for a tractor-trailer combination (DIN EN ISO 25119-1:2018) and the best possible accuracy are achieved – even when driving slowly.
The sensors are located in protected areas on the vehicle.
The innovative steering system was presented together with the new Krampe AS 750 push-off trailer. First test drivers are enthusiastic about the experience. The system is currently being adapted to the individual models and can be regularly ordered as additional equipment from the beginning of 2023.
