A dual mass flywheel uses a parallel spiral spring and damping unit to resiliently couple crankshaft and gearbox masses.
Directional friction in the energy storage element dampens resonance while low thrust friction ensures smooth gear changes.
A die cushion device segments support pads into independent units driven by individual servo motors.
Replacing arc springs with lubricant-free torsion springs eliminates sealed channels and contamination sensitivity in high-load applications.
Harder inserts on the sliding block's first surface section reduce wear and abrasion, preventing lubricant contamination in torsional vibration dampers.
