Abstract:
Apparatus for damping torsional vibrations, comprising an input member; an output member rotatable with and relative to said input member about a common axis, said members having annular surfaces which overlie each other in the direction of said axis; resilient means for yieldably opposing rotation of said input and output members relative to each other; and means for centering said input and output members relative to each other, comprising a radial bearing having a sleeve with an internal surface complementary and adjacent to one of said annular surfaces and an external surface complementary and adjacent to the other of said annular surfaces, and a thrust bearing interposed between said input and output members, said sleeve being located at a first radial distance from said axis, said thrust bearing being located at a different second radial distance from said axis and said resilient means being located at a third radial distance from said axis, said third radial distance exceeding said first and second radial distances.
