sidosakselit

Sidosakselit, often translated as side shafts or half-shafts, are a crucial component in many automotive drivetrains, particularly in front-wheel drive and all-wheel drive vehicles. Their primary function is to transmit rotational power from the differential to the wheels. Each driven wheel is connected to the differential by a separate sidosakseli. These shafts are typically designed with universal joints or constant velocity (CV) joints at both ends. These joints are essential for accommodating the changes in angle and length that occur as the suspension moves and the wheels steer. The CV joints allow for smooth power transfer even when the shaft is at an angle, preventing the jerky or vibrating motion that would occur with a rigid connection. Sidosakselit are usually made of hardened steel to withstand the torque and stress they endure. They are a common point of failure, with CV joint boots being particularly susceptible to damage, leading to wear and eventual failure of the joint itself.
