Abstract
A torsional vibration damper assembly to provide extended travel for the dampening effect which is achieved by the use of two concentric series of damper springs interconnected through a common housing or intermediate member. A driving plate has two or more drive tangs secured thereon, which tangs extend inwardly into the path of the outer circle of damping springs. One or more floating divider rings are journalled in the assembly and have ears projecting into the path of the springs as do outer drive straps of the intermediate member. Floating wedges or skates are located between the springs of the inner circle along with inner drive straps of the intermediate member and hub arms in the path of the inner springs; the hub being driven through the circles of springs to drive a transmission input shaft.
