Abstract: The present disclosure deals with the above problems by providing a TRAS architecture having a fully distributed motor configuration—i.e. having a single, smaller motor, for each actuator. The efficiency of the drive between the motor and the actuator output to which it is connected is maximised, but the efficiency of the mechanical connection between adjacent actuators themselves is minimised (preferably less than 50%) resulting in low torque transfer between actuators.

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.
