Abstract
A progressivity device for a friction clutch disc includes a support flange, having a central axis of rotation, in which an annular central part is designed to cooperate with a torsional vibration damper, and an external part bears progressivity blades and friction pads attached to the progressivity blades. The progressivity blades extend circumferentially over at least one of the faces of the support flange. The progressivity blade include one end fixed to the external part, another free end and folds delimiting a support region for the friction pad.
Claims16
A progressivity device for a friction clutch disc, comprising:
- a support flange, having a central axis of rotation, in which an annular central part is configured to cooperate with a torsional vibration damper, and an external part carries progressivity blades and friction pads attached to the progressivity blades, wherein the friction pads are attached to and directly abut a first side of the progressivity blades,
- wherein the progressivity blades extend circumferentially over at least one of the faces of the support flange,
- wherein each of the progressivity blades comprises one end fixed to the external part, another free end and folds delimiting a support region for the friction pad, the friction pad associated with the progressivity blade covering the end fixed to the support flange, and
- wherein the free end of each of the progressivity blades is retained at least partially axially with respect to the support flange by the fixed end of the adjacent progressivity blade when the progressivity device is freed from all axial compression force.
A progressivity device for a friction clutch disc, comprising:
- a support flange, having a central axis of rotation, in which an annular central part is configured to cooperate with a torsional vibration damper, and an external part carries progressivity blades and friction pads attached to the progressivity blades, each friction face of the progressivity device comprises separate friction pads having an angular segment shape,
- wherein the progressivity blades extend circumferentially over at least one of the faces of the support flange,
- wherein each of the progressivity blades comprises one end fixed to the external part, another free end and folds delimiting a support region for the friction pad, the friction pad associated with the progressivity blade covering the end fixed to the support flange, and
- wherein each of the friction pads comprises an intercalary foil, the intercalary foil bearing axially on the intercalary foil of the adjacent friction pad when the progressivity device is freed from all axial compression force.
