A two-joint drivetrain component incorporating a central centering yoke connects two universal joints. This configuration accommodates significant operating angles between input and output shafts while minimizing speed fluctuations often associated with single universal joint driveshafts. This design is frequently employed in vehicles with substantial suspension articulation or where the driven component’s angle varies considerably relative to the power source.
The central centering element maintains a constant velocity ratio between the driving and driven shafts, reducing vibration and wear. This characteristic is particularly valuable in high-torque applications and contributes to smoother power delivery, improved vehicle handling, and extended component lifespan. Originally developed for industrial machinery, this design was later adapted for automotive use, becoming essential in four-wheel-drive systems and other applications requiring substantial drivetrain flexibility.
