folyadékhajtóm

A folyadékhajtóm, often translated as hydraulic drive or fluid drive, is a mechanical system that transmits power from a source to a driven component using a pressurized liquid as the medium. This system typically consists of a pump, a motor, and a connecting fluid. The pump, driven by an engine or electric motor, pressurizes the fluid, which then flows through a closed circuit to the hydraulic motor. The motor, in turn, converts the fluid pressure and flow back into rotational or linear mechanical motion, thereby driving the desired output.

The key principle behind a folyadékhajtóm is Pascal's law, which states that pressure applied to an enclosed fluid is transmitted undiminished to every portion of the fluid and the walls of the containing vessel. This allows for significant force multiplication and precise control over speed and torque. Common applications include heavy machinery like excavators and bulldozers, as well as automotive systems such as automatic transmissions and power steering. The ability to transmit power smoothly, absorb shocks, and operate in harsh environments makes folyadékhajtóm systems highly versatile. Maintenance typically involves monitoring fluid levels and pressure, and occasional replacement of seals and filters to ensure optimal performance and longevity.
