A rotating element transmits mechanical power from the engine to the differential, which then delivers power to the wheels. This system often incorporates a U-shaped part that connects the shaft to the differential, facilitating power transfer through changes in angle and distance.
This power transmission system is essential for vehicle propulsion, enabling controlled movement. Its design allows for flexibility and accommodation of suspension movement, crucial for a smooth and efficient driving experience. Early automobiles relied on simpler mechanisms, but the development of this more sophisticated system significantly improved vehicle performance and reliability.
