Claims15
A rotary shaft for use in the drive line of a motor vehicle, the shaft comprising:
- a liner, including a cardboard layer and a ceramic layer, wherein the liner is selectively coupled to a portion of the shaft to absorb vibration energy of the rotary shaft and increase the resonant frequency of bending of the shaft, wherein the liner farther comprises a substrate comprising a wire mesh, wherein the ceramic layer is deposited atop the substrate.
A shaft for use in a motor vehicle comprising;
- a tube section;
- and
- a liner having a heat resistant layer that comprises cardboard,
- wherein the liner further comprises a substrate comprising a wire mesh, and wherein the substrate is at least partially coated with ceramic;
- wherein said liner is coupled to a surface of said tube section, said liner increases the resonant frequency of the shaft.
