DISPOSITIVO AMORTIGUADOR DE TORSION PERFECCIONADO.

摘要

A flexible center type friction clutch plate including a pair of identical annular guiding plates and a hub with a radially outwardly extending web intermediate thereof. Passages are provided along the periphery of both of the annular guiding plates. The passages in one of the annular guiding plates serve to mount the friction disc secured thereto by rivets. The passages in the other annular guiding plate which hitherto were left unused serve to mount friction shoes which enhance the "hysteresis" effect complementing that provided by the friction washers between the web and one of the annular guiding plates. By choosing the number of friction shoes in the passages the precise hysteresis effect may be achieved.
