Abstract:
A transmission comprising housing and an axially compliant hub having a central plate with an axial opening and an outer circumference. The central plate is attached to the attached to the circumference with at least one strap spring. A method of managing axial stack up in a transmission is also disclosed where the transmission has a plurality of planetary gear sets aligned in series and at least one torque transmitting device. The planetary gear has gear members. The method includes providing a an axially compliant hub having a central plate with an axial opening and an outer circumference, wherein the central plate is attached to the attached to the circumference with at least one strap spring and wherein the outer circumference is connected to the torque transmitting device and wherein the central plate is connected to a gear member of a planetary gear set.
