The efficiency of a skid-steer, all-wheel drive, multiple-axle vehicle with a hydrostatic drivetrain equipped with low-speed motors when it operates on soft terrain was studied. A flow divider enables a single pump to simultaneously power more than one motor circuit with different pressures in each. It prevents kinematic discrepancy and improves vehicle mobility. There are two types of flow divider: spool type and gear type, where each type has its own set of performance characteristics, such as flow range, pressure drop, accuracy and application parameters. In the present work, the influence of the characteristics of both types of flow divider on overall vehicle driveline efficacy is described.

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.

The study presents the issue of kinematic discrepancy of hydrostatic drive systems of high mobility vehicles, and its impact on the presence of the unfavourable phenomenon of circulating power. Furthermore, it presents a theoretical discussion concerning the capacity of the compensation of kinematic discrepancy by a hydrostatic drive system on the basis of tests using static characteristics.
