Drivværk

Drivværk is the set of components that transmits mechanical power and motion from a primary source to the working parts of a machine. The term is commonly used for wheeled vehicles but also applies to industrial machinery, robotics, and any system where motion and torque must be transferred and controlled.

Core elements include a power source (such as an internal combustion engine, electric motor, or hydraulic motor), a means of adjusting speed and torque (transmission or variator), a drive path (belt, chain, or shaft), and a final stage that delivers torque to the output (gears, axles, or wheels).

Vehicle drivværk typically incorporates a differential to allow wheels to rotate at different speeds, and may include clutches, gears, or electronic control for engagement. In machinery, belt drives, chain drives, or gear trains are common methods to transfer power between pulleys, sprockets, or gears.

Different configurations exist depending on application. Automobiles may be front-, rear-, or all-wheel drive, with manual, automatic, semi-automatic, or continuously variable transmissions. Industrial drivværk emphasizes efficiency and reliability, often prioritizing compactness and serviceability.

Design and maintenance focus on matching torque and speed to the load, minimizing losses, and ensuring durability. Regular inspection, lubrication, tension checks for belts or chains, bearing wear assessment, and proper alignment are important for longevity.
