Abstract
Two components, such as an engine block (1) and a gear case (2), are coupled to each other by at least two flexible coupling links (7, 8) and by a rigid coupling link (10). One end of each flexible coupling link is connected to the engine block or gear case by a first screw connector (11, 11A, 11B) having a threaded bolt (13) passing through a twin cone (16) acting as a centering member. The conical surfaces of the twin cone centering member (16) cooperate with respective conical surfaces (12) in the gear case (2) and in an expander ring (17) bearing with its outer surface against an inner surface of a hole in the coupling link (7, 8) or an intermediate bushing in the coupling link, whereby the force transmitting connection is accomplished with radial clamping forces. The cooperation of the conical surfaces compensates for alignment tolerances and uneven stress distributions are avoided.
