A Cardan Joint, also known as a universal joint, is a mechanical device that allows the transmission of rotary motion between two shafts that are not in line with each other. It consists of two yokes connected by a cross-shaped component, enabling flexibility in movement while maintaining torque transfer. This design is commonly used in various applications, including vehicles and machinery. The Cardan Joint is essential in systems where shafts need to connect at angles, such as in the drive shafts of automobiles or industrial equipment. Its ability to accommodate misalignment helps improve efficiency and reduce wear on components.
