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.

A dual mass flywheel, comprising:
- a first mass member connected to an engine output shaft;
- a second mass member connected to a transmission input shaft, the second mass member and the first mass member rotatable about one another within a predetermined range of motion;
- a drive plate fixedly connected to the second mass member;
- and
- a dampening assembly interposed between the first mass member and the drive plate, the dampening assembly using air dampening to perform a dampening operation during a process of transmitting torque from the engine output shaft to the transmission input shaft, wherein the dampening assembly comprises:
- a compressible piece;
- a pair of resilient guides, each directly mounted to opposite sides of the compressible piece;
- a pair of resilient adapters, each mounted to a end of a respective one of said guides at a position remote from the compressible piece;
- and
- a pair of idle springs, each mounted between a respective adapter of the adapters and the compressible piece.
