Abstract:
1. A torsional vibration damper for a bridge clutch in a hydrodynamic clutch device, the bridge clutch having a piston axially movable between predetermined axial limit positions defining a maximum axial deflection of the piston, said torsional vibration damper comprising: at least one damping unit comprising a drive-side transmitting element and a power takeoff side transmitting element; an angle of rotation limiter for said at least one damping unit including a projection extending from one of said drive-side transmitting element and said power takeoff-side transmitting element, the other one of said drive-side transmitting element and said power takeoff-side transmitting element defining a recess in at least a first area thereof, the recess being arranged and dimensioned for accepting said projection and having a circumferential dimension allowing a predetermined relative deflection between said drive-side transmitting element and said power takeoff-side transmitting element; and a seating component, at least a second area of said other one of said drive-side transmitting element and said power takeoff-side transmitting element being supported on and attached to said seating component, said projection engaging said recess with a predetermined axial play relative to said seating component, said predetermined axial play corresponding to at least said maximum axial deflection of the piston.
