Torsion vibration damper has elongate impressed areas formed on shaped sheet metal portion between support areas and extend over length of mountings when viewed in circumferential direction

摘要

Elongate impressed areas (23) are formed on the shaped sheet metal portion (11) between the support areas and extend over the length of the mountings when viewed in the circumferential direction and in the extension region of the mountings. The impressed support areas for the energy accumulators of a damping device are formed between the mountings when viewed in circumferential direction. The torsion vibration damper has two flywheel masses rotatable relative to each other, in which one flywheel mass is connected to a motor while the other is connected to a gearbox. The damping device is set between the flywheel masses to counteract the relative rotation of the flywheel masses. One of the flywheel masses is formed by the disc-shaped sheet metal portion which is radially on the outside circumferentially extending mountings for the energy accumulators.
