Dual mass flywheel for combustion engine crankshafts has primary flywheel mass with radially inner flange and radially outer flange as separate parts and connected axially elastically through connecting device

摘要

The dual mass flywheel comprises a primary flywheel mass (1) and secondary flywheel mass (2) coupled together through a torsion vibration damper (3). The primary mass has a radially inner flange (5) and a radially outer flange (6) connected axially elastically through a connecting device (7). The connecting device comprises a highly tensile material such as spring steel and has a spring-elastic disc. The secondary mass is coupled through a hub disc (4) to the torsion vibration damper.
