Assessment of load of drive axles of self-propelled modular vehicles under different operating modes

Abstract

This paper presents an assessment of the load on the drive axles of self-propelled modular trailers (hereinafter referred to as SPMT) under various modes. SPMT is used for transportation of oversized heavy cargo. The article describes the features of the SPMT and the design of the drive axle using the example of the Cometto MSPE EVO2. Based on the technical characteristics of the SPMT determines the dependence of the maximum rotation speed of the input shaft of the drive axle on torque for various configurations. The obtained dependence allows us to determine the movement parameters of the SPMT: the maximum speed for each configuration depending on the load conditions (axial load and longitudinal slope of the road). Based on the calculated operating parameters of the SPMT, the travel time for the transportation route can be determined and the necessary configuration can be selected to overcome the route with known characteristics (longitudinal slope) with a specific cargo weight.
