DETERMINATION OF HIGH-SPEED RANGES OF MULTIPURPOSE WHEELED AND TRACKED VEHICLES WITH ELECTROMECHANICAL TRANSMISSION

Abstract

All-terrain vehicles are designed for traffic in various road and ground conditions, therefore the use of electromechanical transmissions leads to difficulties caused by the increase in their dimensions, weight and reduction of power. An effective solution to this problem is the use of several speed ranges in the transmission. A method for selecting high-speed ranges for a multi-purpose wheeled or tracked vehicle with an electromechanical transmission has been proposed. The expediency of using two ranges in transport vehicles transmission was justified. It was proposed that the choice of ranges was to be based on the purpose of the machine. The two rather different laws of the speed distribution of a transport vehicle were considered. The determination of speed boundaries by these laws was proposed to be made with the help of a statistical approach. At the same time, the average speed was used as a required target indicator in the methodology. The selection of ranges for several perspective wheeled and tracked vehicles was made. Basing on the results obtained and stated in the article, conclusions were drawn to specify the values of the transmission boundaries and the influence of engine power on them.
