A crucial component of front-wheel, rear-wheel, and all-wheel drive vehicles, this mechanism transfers power from the transmission to the wheels while accommodating changes in shaft angle and length due to suspension movement and steering. Imagine the front wheels of a car turning the distance and angle between the transmission and the wheels constantly shift. This flexible coupling allows for smooth power delivery despite these variations.
Its presence ensures a vibration-free and efficient transfer of engine power, improving vehicle handling, passenger comfort, and overall drivetrain durability. Before its widespread adoption, simpler universal joints, prone to vibration and uneven power transmission at higher angles, were common. This innovation revolutionized vehicle design, enabling smoother operation, especially in front-wheel drive systems, which became increasingly popular.
