Definition

1. Noun:
   • A hydraulic transmission system is a mechanism for transferring power from an engine to a point of application (like wheels or machinery) that uses the force of a pressurized fluid, typically oil, instead of mechanical gears or belts.

Usage

• The term is used to describe a specific type of power transmission technology, common in heavy machinery, industrial equipment, and some vehicles.
• It is often discussed in engineering, automotive, and mechanical maintenance contexts.

Examples

• Noun:
  • The bulldozer's hydraulic transmission system allows for smooth and powerful control of its tracks.
  • A failure in the hydraulic transmission system caused the forklift to stop moving.
  • Compared to a mechanical gearbox, a hydraulic transmission system can provide continuous variable speed.

Advanced Usage

• The system is a key component in hydrostatic drives, where it provides infinitely variable speed control.
• It is often contrasted with mechanical transmission systems or electric transmission systems.

Variants and Related Words

• Hydraulic transmission (n): A common shortened form with the same meaning.
• Fluid drive (n): A broader term that can refer to hydraulic transmission systems or other fluid-based couplings.
• Hydrostatic transmission (n): A specific, common type of hydraulic transmission system where the pump and motor are directly connected by fluid lines.

Synonyms

• Hydraulic drive: A very close synonym emphasizing the method of power transfer.
• Fluid power transmission: A more general synonym that includes hydraulic and sometimes pneumatic systems.

Related Phrases

• Transmission fluid: The specialized oil used within a hydraulic transmission system.
• Hydraulic pump: The component that creates the fluid flow and pressure within the system.
• Hydraulic motor: The component that converts the fluid pressure back into rotational mechanical power.

Noun

1. a transmission that depends on a hydraulic system
