Double mass flywheel for motor vehicle internal combustion engine

摘要

The automotive flywheel has two weights (2, 3) and de-couples the motor from the drive train. The primary and secondary masses are linked by springs (8) which allow relative movement between the two, and tends to pull the two weights together. The springs de-couple esp. frequencies in the super-critical range above the flywheel resonance frequency. The two weights (2, 3) are linked by an axially-tensioned spring (8) whose counter thrust bearing, defined by the pressure ring (9), and flywheel part (3), changes the axial distance between the two masses.
