Patent ID: 8529361

Claim:
A drive shaft, comprising: a metallic and hollow shaft shank having load transfer elements integrally formed onto its ends, the shaft shank including: a metal tube prefabricated as a semi-finished part, configured for transmission of torsional loads and having a constant wall thickness, and a reinforcement layer positioned on an exterior of the metal tube configured for ensuring a bending stiffness on the surface of the metal tube, the reinforcement layer having an inner fiber-composite layer with fibers oriented in a longitudinal direction of the drive shaft, wherein, the reinforcement layer includes an outer fiber-composite layer having fibers oriented at an angle of 60° to 90° relative to the longitudinal direction; an intermediate layer provided between the metal tube and the inner fiber-composite layer; wherein the intermediate layer is configured as a sliding layer to compensate for heat-related longitudinal expansions.
