  • Hybrid metal-composite drive shaft unit and method of manufacturing same
    Patent number: 10280969
    Abstract: A hybrid metal-composite drive shaft unit, which comprises at least one metal drive shaft connector that is at least partly embedded into a composite drive shaft, the composite drive shaft comprising a thermoplastic polymer and being connected to the at least one metal drive shaft connector by means of a welded connection that defines a first load path for transmission of loads between the at least one metal drive shaft connector and the composite drive shaft, the at least one metal drive shaft connector and the composite drive shaft comprising, in the region of the welded connection, at least partly a polygonal cross-sectional shape for forming a form-fit connection that defines a second load path for transmission of loads between the composite drive shaft and the at least one metal drive shaft connector.
