Traditionally, hydrostatic transmissions of specialised transport vehicles use piston hydraulic machines to move the vehicle, as well as to operate attachment systems and units. For a wide range of special vehicles used in agriculture and municipal services, movement requires the power of the drive motor, comparable to the power of gear hydraulic machines. Gear hydraulic machines are less demanding on the quality, viscosity, and purity of the working fluid, are cheaper, and are easier to operate. Regulation of speed of an output shaft of gear hydraulic motors, as a rule, is provided by the thr

The article considers the relevance of the selection of hydraulic drive elements for construction and lifting and transport machines. Currently, hydraulic drive is widely used on construction and lifting machines. The hydraulic drive includes a hydraulic motor, which can be either a hydraulic cylinder or a hydraulic motor. When selecting during operation or during the design of these units, it is important to know the pressure losses in the suction, pressure and drain hydraulic lines. The process of determining these losses is very laborious. Computer programs can be used to automate the proce

Submerged cargo pumps installed on board tankers are one of the most important components of their cargo system. As they are installed directly in the cargo tanks, they are usually equipped with a hydraulic drive whose power and capacity are controlled by constant-torque controllers. These have a significant impact on the technical and performance characteristics of the cargo pumps. This paper presents a methodology for calculating the performance characteristics of submerged cargo pumps, taking into account the energy efficiency of their hydraulic drive motors. Due to their number and power,

Abstract In basic hydraulic theory, efficiency is dependent on volumetric and mechanical losses. Components dominated by mechanical losses favor low viscosity fluids, while those dominated by volumetric losses favor high viscosity fluids. For a hydrostatic transmission (HST), efficiency of both the pump and motor must be considered. The goal of this work is to model the HST viscosity-efficiency curve for finding the optimal viscosity and to validate the results with experiments.
