kardánhajtást

Kardánhajtás, also known as a driveshaft or propeller shaft, is a mechanical component used to transmit torque and rotation between two parts of a system, typically in vehicles. It is a crucial element in rear-wheel drive and all-wheel drive vehicles, connecting the transmission or transfer case to the differential. The driveshaft is essentially a tube or rod with universal joints (U-joints) or constant velocity (CV) joints at each end. These joints allow the shaft to operate at an angle, which is necessary because the transmission and the differential are not always perfectly aligned, especially when the suspension moves.

The primary function of a kardánhajtás is to transfer power from the engine's output to the drive wheels. In a rear-wheel drive car, this means sending power from the transmission to the rear differential. In an all-wheel drive system, it might connect the transfer case to either the front or rear differential, or both. The design of the kardánhajtás must account for various operating conditions, including changes in length due to suspension travel and angular misalignment. The use of U-joints or CV joints ensures smooth power delivery even under these dynamic conditions. Wear and tear on these joints can lead to vibrations or noises, indicating a need for inspection or repair.
