Abstract
A torsional vibration dampener assembly having resilient means to provide a variable torque output in conjunction with variable damping friction torque. The assembly utilizes a first set of torsion springs to provide a low deflection or displacement rate for a first stage of travel between the input and output members and a second set of springs providing an increased deflection rate for a second stage of travel, and a cooperating cam construction which can be arranged to provide an increase or decrease in damping friction as required in relation to the transmitted torque.
