Hydrostatic transmission is a type of transmission system that uses hydraulic fluid to transfer power from the engine to the wheels or other moving parts of a machine. Unlike mechanical transmissions that rely on gears and clutches, a hydrostatic transmission uses a hydraulic pump to convert mechanical energy from the engine into hydraulic energy, which is then used to drive hydraulic motors connected to the wheels or tracks.

How Hydrostatic Transmission Works

Hydraulic Pump: The system starts with a hydraulic pump, typically a variable displacement pump, which is driven by the engine. This pump pressurizes hydraulic fluid, creating a flow of high-pressure fluid.
Hydraulic Motors: The pressurized fluid is then directed to hydraulic motors, which convert the hydraulic energy back into mechanical energy to drive the wheels, tracks, or other components. The speed and direction of the machine can be controlled by adjusting the flow of hydraulic fluid to these motors.
Control Mechanisms: The operator controls the hydrostatic transmission system via pedals or levers, which adjust the displacement of the hydraulic pump and the flow of hydraulic fluid, allowing for smooth, variable speed control and forward/reverse operation without the need for shifting gears.

Benefits of Hydrostatic Transmission

Smooth and Precise Control: Hydrostatic transmission provides smooth and precise control over the machine's speed and direction, making it ideal for applications that require fine adjustments, such as grading, loading, or maneuvering in tight spaces.
Infinitely Variable Speed: The system allows for infinitely variable speed control, enabling the operator to adjust speed smoothly from zero to maximum without shifting gears.
Enhanced Operator Comfort: The lack of gear shifts and the smooth operation of hydrostatic transmission systems reduce operator fatigue, allowing for extended work periods.
High Efficiency in Low-Speed Operations: Hydrostatic transmissions are particularly efficient at low speeds, making them well-suited for applications where precise, slow-speed control is necessary.

Hydrostatic Transmission in Hydrema Machines

We incorporate hydrostatic transmission into several of our machines to enhance maneuverability and control. This advanced transmission system is featured in:

Hydrema 912G-Series Dump Trucks: Our 912G dump trucks benefit from hydrostatic transmission’s ability to provide smooth and controlled operation, especially in challenging terrains and confined spaces.
Hydrema 707G-Series Dump Trucks: The compact design of our 707G dump trucks, combined with hydrostatic transmission, ensures exceptional maneuverability and precise speed control, making them ideal for urban and smaller job sites.
Hydrema Wheeled Excavators: Hydrostatic transmission in our wheeled excavators allows for smooth and precise movements, enabling operators to perform tasks that require accuracy, such as trenching and fine grading.

Hydrostatic transmission in Hydrema machines ensures that operators have the control and responsiveness needed for tasks requiring precise movements and consistent power delivery, particularly in challenging or confined workspaces.
