Abstract
A spring retainer assembly, including: a flange plate; a plurality of springs in contact with a radially outer portion of the flange plate; a first cover plate; a second cover plate; a spring retainer; and at least one fastening device. The spring retainer and the first plate substantially surround respective outer circumferences of the plurality of springs; and the at least one fastening device is for fixedly connecting the spring retainer to a torque-transmitting device. In one embodiment, the spring retainer is axially fixed by the connection to the torque-transmitting device and includes a first portion, and contact of the first portion with the first plate positions the first plate in a desired axial position with respect to the plurality of springs. In one embodiment, the spring retainer includes a plurality of protrusions and a circumferential end for each spring is in contact with a respective protrusion.
