Abstract
A multiple-piece backing plate and a friction clutch assembly for an automotive transmission are provided. The multiple-piece backing plate includes a cap part and a main body backing plate. The cap part is formed of a first material. The main body backing plate is attached to the cap part, and the main body backing plate is formed of a second material, where the second material is different than the first material. The friction clutch assembly includes first clutch plates coupled to a first transmission member and second clutch plates interleaved with the first clutch plates and coupled to a second transmission member. The friction clutch assembly is configured to be moved between an engaged position and a disengaged position. In the engaged position, the first and second transmission members are coupled together by compressing the first and second clutch plates directly against the cap part.
