Abstract
A damper between coaxial input and output members in the composite flywheel of a motor vehicle has a pair of elongated arcuate coil springs which alternate with the radially outwardly extending arms of a flange-like component. The arms have first sides which stress the adjacent first end convolutions of the springs during rotation of the two members relative to each other in a first direction (e.g., when the engine drives the wheels), and second sides which stress the adjacent second end convolutions of the springs during rotation of the two members relative to each other in a second direction (e.g., when the vehicle is coasting). At least one side of at least one arm is different from at least one other side; for example, the at least one side can have one or more projections or a recess for the radially outermost part of the adjacent end convolution.
