Abstract
There is proposed an assembly for damping vibrations in a torque transmitting arrangement between an engine and an input part of a transmission. The assembly comprises a first flywheel connected to the engine, and a second flywheel connectable to the input part of the transmission. The first and second flywheels are rotatable relative to each other. At least one damper includes spring means operative to resiliently oppose rotation of the flywheels relative to each other. The assembly also comprises at least one lock-up mechanism including centrifugal force responsive means operative to prevent rotation of the flywheels relative to each other after the damper has become idle when rotation of the engine is lower than a predetermined speed value.
