Dual-mass flywheel for power-train of motor car, has energy storage section having outer and inner bow springs which are mutually secured against displacement by sliding fasteners by turns which are spaced apart from front end turns

摘要

The dual-mass flywheel (1) has energy storage section (11) between primary and secondary flywheel masses (3,15). The energy storage section has outer and inner bow springs (12,13) which are compressed on flange (17) through the solicitation element by the rotation of the flywheel masses in pull direction and thrust direction. The springs are mutually secured against displacement by sliding fasteners (4) by several turns which are spaced apart at a predetermined distance from front end turns in the circumferential direction of the dual-mass flywheel.
