Abstract:
A flexible disk coupling for a drive train between a combustion engine and a transmission of a motor vehicle, said flexible disk coupling comprising:a first coupling half including two side disks and an outer circumference interconnecting said two side disks;a second coupling half surrounded by said two side disks of said first coupling half, said second coupling half including a hub and at least one disk associated with said hub;a plurality of flexible coupling elements interconnecting said first coupling half and said second coupling half such that said first coupling half and said second coupling half have limited torsion relative to each other;a substantially liquid-tight inside chamber defined by said two side disks of said first coupling half, said inside chamber receiving said at least one disk of said second coupling half, said inside chamber being configured for being filled with a damping medium;a floating damping ring disposed within said inside chamber, said floating damping ring having limited torsion relative to said first coupling half and said second coupling half;a first displacement chamber defined by said first coupling half and said floating damping ring, said first displacement chamber having a variable volume; andat least one second displacement chamber defined by said second coupling half and said floating damping ring, said at least one second displacement chamber being in fluid communication with said first displacement chamber, said at least one second displacement chamber having a variable volume.
