Answer;
The dual mass flywheel
The dual mass flywheel has a center support bearing that carries the load between the inner and the outer flywheel and is fitted with damper springs to absorb shocks.
Explanation;
The dual mass flywheel eliminates excessive transmission gear rattle, reduces gear change/shift effort, and increases fuel economy. There are two basic types of Dual Mass Flywheels. The first is made up of a primary and secondary flywheel with a series of torsion springs and cushions.
-There is a friction ring located between the inner and outer flywheel that allows the inner and outer flywheel to slip. This feature is designed to alleviate any damage to the transmission when torque loads exceed the vehicle rating of the transmission. The friction ring is the weak spot in the system and can wear out if excessive engine torque loads are applied through it.
