As cooperation partner in the BMBF-project SoilAssist, STEYR is jointly working with other companies to protect agricultural soils. In addition to the tire and wheel specialist Grasdorf GmbH, and TerraCare as a specialist for tire pressure control systems, Thünen-Institute as initiator of the project also involved STEYR tractors as further partner. Among other things, the project focusses on an "intelligent" wheel: An ultrasonic sensor measures the distance between the rim and the ground. On this basis, the maximum permissible deflection of the tire, the respective tire inflation pressure, and thus the contact area with the ground can all be optimised, thus providing optimum protection for the soil. Damage to the tire caused by excessive deflection and subsequent overheating is avoided. This also benefits the durability of the tires.
During the project, cooperation partners want to work on a tractor-wheel-combination that independently recognises working and load situations, automatically selecting and adjusting the optimum inflation pressure. Taking such decisions off the driver by automatic procedures is expected to lead to a substantial improvement towards sustainable soil conservation along with minimum slip and fuel consumption. The intelligent tire will be on display at the ErlebnisBauernhof in fair hall 3.2 of International Green Week (IGW) in Berlin.
"We are pleased that also with this project, we can work on solutions towards sustainable land management. Together with our cooperation partners, we want to continue working on this venture, and focus on soil protection and sustainable land management", says Hans-Werner Eder, Product Marketing Manager STEYR.
