Abstract
The first part of the paper presents the construction of the central pressure control system of tyre inflation pressure for the four-wheel drive agricultural tractor (U1010 DT), using components from an all-road military wheel vehicle. From the compressed air reservoir the air is directed to the central pressure control system, where from, by means of the rotating valves mounted in the axes of the axles, the air reaches the tyres. The last section of the paper presents the results of experimental research conducted on the influence of the air volume in the reservoir on the response rate of the real-time control system of tyre inflation pressure. The developed and experimentally tested constructive solution can be applied to tractors already in use with minimal adaptations depending on the concrete construction of the tractor, or can be included as an option in axle manufacturing.
