Abstract:
Apparatus for damping torsional vibrations, comprising:a first flywheel rotatable about a predetermined axis and connectable to a rotary output element of a combustion engine;a starter gear provided on said first flywheel;a second flywheel coaxial with and rotatable relative to said first flywheel and arranged to transmit torque from said first flywheel to an input element of a transmission by way of a friction clutch, one of said flywheels defining an annular chamber and including first and second walls having portions extending substantially radially of said axis and flanking said chamber, said walls further having radially outer parts surrounding said chamber and being affixed to each other;bearing means interposed between and arranged to position said flywheels relative to each other; andtorque transmitting damper means arranged to yieldably oppose rotation of said flywheels relative to each other, being at least partially confined in said chamber and including torque transmitting energy storing means, said energy storing means reacting against abutment means of one of said flywheels and bearing against at least one portion of at least one of said walls, said at least one wall having at least one recess extending substantially circumferentially of said flywheels and in the axial direction of said first flywheel, said at least one portion of said at least one wall being provided in said at least one recess.
