Driveshaft components including axles and CV joints are subject to rigorous loading conditions in passenger cars and trucks. These components consist often of metallic and elastomeric components. It is important to test these components in fatigue and durability. Zwick offers a complete line of torsion and rotary test machines called Torsionline designed for these applications with a torque range of 200 to 6000 Nm. testControl and testXpert® software are used to control and to obtain and analyze test results from these systems.
