Abstract:
A torque transmitting device having a spring pack assembly, includes a first spring retainer ring abutting a hydraulically actuated piston, a second spring retainer ring abutting a piston housing, and a plurality of coiled springs biasing the first spring retainer ring apart from the second retainer ring, thereby urging the hydraulically actuated piston slideably apart from the fixed piston housing. A composite spring support ring is coaxially disposed between the first spring retainer ring and the second spring retainer ring. The spring support ring includes cylindrical walls defining cylindrical passageways configured to receive the coiled springs. Each of the cylindrical passageway includes include a diameter (d) that is sufficiently narrow such that the cylindrical wall completely surrounds the mid-portion of the coiled spring thus preventing the coiled spring from bending lengthwise, but sufficiently wide such that the coiled spring does not saw into the cylindrical walls.
