The article presents a study of known methods to enhance the off-road mobility of all-wheel multi-axle trucks operating on roads with low bearing capacity in agricultural tasks. The relevance of study aimed at assessing the effectiveness of using decentralized tire pressure is substantiated. This paper proposes a methodology for analyzing the relationship between the rolling resistance coefficient of the wheels and parameters such as tire pressure, vertical load, and axle number, as well as methods and equipment for experimental fuel consumption determination in accordance with GOST R 54810-2011.
The article presents the results of theoretical studies, based on which optimal tire pressure values for each axle of the all-wheel multi-axle truck moving on loose soil are recommended: n=1 Рt =0.2 MPa, n=2 Рt=0.3 MPa, n=3 Рt=0.5 MPa. Experimental tests revealed that using decentralized tire pressure of the all-wheel multi-axle truck moving on loose soil reduces average fuel consumption by up to 12.1%. The study results can be applied to the operation of all-wheel multi-axle trucks in challenging road conditions to improve their technical and operational performance.
