  "abstract": "A shipping strap for a hybrid module includes a first annular surface, a second annular surface, and a central bore. The first annular surface includes a first orifice for receiving a first fastener for fixing the shipping strap to a hybrid module housing, or receiving a dowel pin for radially positioning the shipping strap relative to the hybrid module housing. The second annular surface includes a second orifice for receiving a second fastener for securing the shipping strap to a rotor for an electric machine to axially position the rotor in the hybrid module housing. In some example embodiments, the shipping strap has a through bore aligned with the central bore, and a lifting element installed in the central bore for installing the hybrid module in a multi-speed transmission. In an example embodiment, the lifting element is installed in the central bore by a threaded connection.",
  "claims": [
    "1. A shipping strap for a hybrid module, comprising: a first annular surface including a first orifice for: receiving a first fastener for fixing the shipping strap to a hybrid module housing; or, receiving a dowel pin for radially positioning the shipping strap relative to the hybrid module housing; a second annular surface, radially inside of the first annular surface and axially offset from the first annular surface, comprising a second orifice for receiving a second fastener for securing the shipping strap to a rotor for an electric machine to axially position the rotor in the hybrid module housing; and, a central bore arranged for receiving a pilot of the rotor for radially positioning the rotor in the hybrid module housing. 2. The shipping strap of claim 1 further comprising: a through bore aligned with the central bore; and, a lifting element installed in the central bore for installing the hybrid module in a multi-speed transmission. 3. The shipping strap of claim 2 wherein the lifting element is installed in the central bore by a threaded connection. 4. A hybrid module comprising: the shipping strap of claim 1; and, the hybrid module housing, wherein the first fastener is a bolt and the shipping strap is fixed to the hybrid module housing by the bolt installed in the first orifice and threaded into the hybrid module housing. 5. A hybrid module comprising: the shipping strap of claim 1; and, the hybrid module housing, wherein the shipping strap is radially positioned relative to the hybrid module housing by the dowel pin installed in the first orifice. 6. The shipping strap of claim 1 wherein: the first orifice is for receiving the first fastener for fixing the shipping strap to the hybrid module housing; and the first annular surface comprises a third orifice for receiving the dowel pin for radially positioning the shipping strap relative to the hybrid module housing. 7. A hybrid module comprising: the shipping strap of claim 6; and, the hybrid module housing; wherein: the first fastener is a bolt; the shipping strap is fixed to the hybrid module housing by the bolt installed in the first orifice and threaded into the hybrid module housing; and, the shipping strap is radially positioned relative to the hybrid module housing by the dowel pin installed in the third orifice. 8. A hybrid module comprising: the shipping strap of claim 1; the hybrid module housing; the second fastener; and, the rotor for the electric machine axially positioned in the hybrid module housing and secured to the shipping strap by the second fastener. 9. The hybrid module of claim 8 further comprising a nut, wherein: the second fastener is a stud fixed to the rotor; and, the nut is installed on the stud to secure the rotor to the shipping strap. 10. A hybrid module comprising: the shipping strap of claim 1; the hybrid module housing; and, the rotor for the electric machine comprising the pilot installed in the central bore to radially position the rotor in the hybrid module housing. 11. A hybrid module comprising: a hybrid module housing; a rotor for an electric machine, comprising a pilot; and, a shipping strap comprising: a first annular surface including a first orifice; a second annular surface, radially inside of the first annular surface and axially offset from the first annular surface, comprising a second orifice; and, a central bore; wherein: the shipping strap is secured to the hybrid module by a first fastener installed in the first orifice; the shipping strap is secured to the rotor by a second fastener installed in the second orifice; and, the rotor is radially positioned in the hybrid module housing by the pilot installed in the central bore. 12. The hybrid module of claim 11 wherein the rotor is axially positioned in the hybrid module housing by the shipping strap. 13. The hybrid module of claim 11 further comprising: a torque converter fixed to the rotor; and, a shipping dome fixed to the hybrid module housing for radially and axially positioning the torque converter relative to the hybrid module housing. 14. A method of installing a hybrid module comprising: providing a hybrid module with a hybrid module housing and a rotor; providing a shipping strap; securing the shipping strap to the hybrid module housing and to the rotor; transporting the hybrid module to a transmission assembly facility; installing the hybrid module with a transmission; transporting the transmission to a vehicle assembly facility; removing the shipping strap; and, installing the transmission in a vehicle. 15. The method of claim 14, wherein the shipping strap comprises a lifting element for aiding the step of installing the hybrid module with a transmission. 16. The method of claim 14, wherein the hybrid module comprises a torque converter fixed to the rotor, further comprising: securing a shipping dome to the hybrid module housing before the step of transporting the hybrid module to a transmission assembly facility; and, removing the shipping dome before the step of installing the hybrid module with a transmission. 17.
