jõuülekandmine

Jõuülekandmine, often translated as power transmission or drivetrain, refers to the system of components that transmit power from a source, such as an engine or motor, to a device that uses the power, such as a wheel or propeller. In vehicles, this system is crucial for transferring the rotational motion and torque generated by the engine to the wheels, enabling movement.

The basic components of a typical vehicular jõuülekandmine include the clutch, transmission, driveshaft, differential, and axles. The clutch disconnects the engine from the rest of the drivetrain, allowing for gear changes and stopping without stalling the engine. The transmission, or gearbox, contains a set of gears that can be selected to alter the speed and torque ratio between the engine and the wheels. This allows the vehicle to start moving from a standstill, accelerate, and maintain speed efficiently under varying conditions.

The driveshaft is a rotating shaft that transmits torque from the transmission to the differential. The differential is a special gearbox located typically at the front or rear axle (or both in four-wheel-drive systems) that splits the power between the drive wheels. It allows the wheels on the same axle to rotate at different speeds, which is essential when the vehicle turns, as the outer wheel needs to travel a longer distance than the inner wheel. Finally, the axles connect the differential to the wheels, delivering the final torque to them. The specific configuration and complexity of a jõuülekandmine can vary significantly depending on the type of vehicle, its intended use, and the power source.
