Abstract
A clutch comprises an input shaft, an output shaft and a biasing member. The biasing member is arranged to provide a biasing force that allows torque transfer from the input shaft to the output shaft via one or more input friction plates and one or more output friction plates. Rotation of the output shaft may cause the biasing force to vary to adjust the maximum torque setting of the clutch during reeling-in or reeling-out of a winch cable around a winch drum. A retainer may be included in the clutch which retains the biasing member in operative connection with the output shaft and translates axially relative to the input shaft upon rotation of the output shaft. The axial translation may cause the biasing force to vary by varying the compression of the biasing member.
