ABSTRACT:
The dual mass flywheel includes a first mass member connected to an engine output shaft. A second mass member is connected to a transmission input shaft. The second mass member is able to undergo rotation with respect to the first mass member within a predetermined range of motion. A drive plate is fixedly connected to the second mass member. A dampening assembly is interposed between the first mass member and the drive plate. The dampening assembly uses air dampening to perform a dampening operation during a process of transmitting torque.
