Abstract
A clutch friction wheel of the kind which is in three parts, especially applicable to industrial vehicles, comprises a friction disc fixed to a damper plate, and guide rings fixed to a support ring which is arranged between the damper plate and the hub. Firstly, the friction disc, damper plate, guide rings, support ring and damping device constitute a first sub-assembly in which the guide rings are secured directly to the support ring on their inner perimeter; secondly, a predamper device acting between the support ring and hub constitutes with the latter a second sub-assembly, in which the predamper device is arranged outside the guide rings on one side of the latter, while a retaining abutment element is disposed axially on the hub on the other side; and thirdly, a mating coupling is arranged between the predamper device and the support ring.
