About the system

The driveline static torsion bench loads half-shafts, CV shafts, propshafts, axles, gearboxes and welded joints with rising torque at very low speed to determine torsional stiffness, yield and fracture strength. The torque-angle curve is recorded with ±0.1% FS torque and ≤0.01° angle accuracy, and fracture is detected automatically. Standard up to 150 kNm and on request 200 kNm and above; the quasi-static version applies ±10 kNm at 2.5–60 r/min.
