Abstract
A friction clutch wherein an intermediate portion of a diaphragm spring is tiltable between two seats which are held in requisite positions by arms bent out from the bottom wall of the clutch housing. The arms extend axially within the seats and through openings provided therefor in the diaphragm spring, thereupon radially outwardly to overlie that side of the seat which confronts the pressure plate of the clutch to thus prevent axial movements of the seats and an intermediate portion of the spring relative to the bottom wall, and finally axially toward the bottom wall to prevent radial expansion of the seat confronting the pressure plate. The seats are or include split wire rings. The seat which is adjacent the bottom wall of the housing is held against radial expansion by an annular holding or clamping device forming part of and extending from the bottom wall of the housing toward the pressure plate. One of the arms, or an additional arm of the bottom wall, can serve to prevent rotation of the seats relative to the housing by extending into gaps between the end portions of the wire rings.
