Hydrostatic drivetrains efficiency of slow-moving terrain vehicles

Abstract

This paper presents issues of hydrostatic drivetrains applied in slow-moving transport terrain vehicles. Short description of such a vehicles was described. Next efficiency of hydrostatic drivetrains and main factors which has influence on its efficiency was discussed. It was characterized two types of hydraulic components efficiency: volumetric and hydro-mechanic. They have detrimental effect on power loses in hydrostatic drivetrains. In final part of the paper efficiency of few hydraulic motors in the same load conditions was compare.
