Advantages of Hydrostatic Transmissions

A hydrostatic transmission provides improved maneuverability, but at a cost. The efficiency of a hydrostatic transmission is always lower than a discrete-gear transmission. A discrete-gear transmission will typically have an efficiency of 95% or greater, meaning that 95% of the … Continue reading

Comparison of Hydrostatic and Mechanical Drives

The same vehicle shown in Fig. 6.1 is shown in Fig. 6.11 with the mechanical transmission replaced with a hydrostatic transmission; all other components remain the same. To provide a specific example, we will begin by specifying a variable displacement … Continue reading

Introduction to Hydrostatic Transmissions

A hydrostatic transmission (HST) is simply a pump and motor connected in a circuit. Other components are added to obtain certain operating features. The four basic configurations of hydrostatic transmissions are : 1. In-line (Fig. 6.10a) 2. U-shape (Fig. 6.10b) … Continue reading

Torque Converters

A torque converter is a hydrodynamic drive component utilizing three (or more) annular bladed parts to absorb power from a prime mover and automatically adjust its operating output speed to match the load demand (Fig. 6.7). The torque converter input … Continue reading
