Abstract

A transmission shaft (100) is provided comprising an input side (20) for inputting torque, an output side (30) for outputting torque, and a rod (10) extending in a longitudinal direction between the input side (20) and the output side (30) to transfer torque along the transmission shaft (100). The rod comprises a first end (10b) provided at the input side, a second end (10c) provided at the output side and a torsional compliant section (10a) extending therebetween providing the transmission shaft with a torsional stiffness. The torsional compliant section comprises a cross-section which extends in the longitudinal direction to define a central core (200) for transmitting torque directly from the first end to the second end and a radially outer section (270). This section also comprises a plurality ribs (210) which extend radially and longitudinally from an outer periphery (260) of the central core for increasing transverse stiffness of the rod (10).
