Abstract

In a torque transmitting torsional vibration damper device for use in a torque transmission path of a motor vehicle between the engine and the gear box a central plate is provided. Two sides plates are provided on both sides of the central plate. The side plates are interconnected for common rotation. Each of the central plate and the side plates is provided with at least two circumferentially extending windows. Respective windows of the central plate and the side plates are aligned in axial direction. Each group of mutually aligned windows receives a pair of torque transmitting compressional springs arranged in series and spaced in circumferential direction. Said discs are provided between the central plate and the side plates. These sides discs are used for circumferential torque transmission between mutually adjacent ends of the compressional springs of each pair. The side discs are supported in radial direction only by engagement with the compressional springs.
