Embodiment Construction

[0079] figure 1 An automobile transmission system 1 according to an embodiment of the present invention is shown. In the example considered, the transmission system 1 is interposed between the crankshaft of the heat engine, not shown, and the input shaft 2 of the gearbox.

[0080] The transmission system 1 includes a friction clutch 3 . The friction clutch 3 includes:

[0081] - movable friction disc 5 rotating around axis X;

[0082] - a flywheel 6 capable of being driven by the crankshaft of the engine, a part 7 of which forms the reaction plate of the clutch; and

[0083] - Torsional vibration damping means 8 to be described below.

[0084] The clutch 3 also includes a pressure plate 9 movable axially under the force exerted by the diaphragm 10 in order to transmit torque from the crankshaft to the input shaft 2 of the gearbox. figure 1 The clutch stop 11 shown in , for example, bears against the diaphragm 10 in order to displace the pressure plate 9 . exist figure 1...

Abstract

The invention provides a friction clutch (3) intended to be inserted between a crankshaft and a gearbox of vehicle. The friction clutch (3) comprises the components of a movable friction plate (5) which rotates around a rotation axis (X); a flywheel (6) which can be driven by a crankshaft, wherein one section (7) of the flywheel forms a reaction plate of the friction clutch (3); and a torsional vibration buffer device (8) which comprises a movable supporting base (25) that rotates around a rotation axis (X), wherein the movable supporting base bears at least one pendulum (29) which moves relative to the movable supporting base (25), wherein the movable supporting base (25) can be permanently connected with the input shaft (2) of the transmission in rotation. Furthermore the pendulum (29) comprises at least one segment which radially extends to outside of the least radial dimension of the segment (7) for forming the flywheel (6) of the reaction plate of the friction clutch (3), particularly outside of the inner diameter.

Description

technical field [0001] The invention relates to a friction clutch for interposition between a crankshaft and a gearbox of a motor vehicle, which friction clutch includes a pendulum torsional vibration damping device. Background technique [0002] A clutch is known from application EP1780434 comprising; [0003] - movable friction disc rotating around an axis; [0004] - a flywheel capable of being driven by the crankshaft and part of which forms the reaction plate of the clutch; and [0005] - A torsional vibration damping device, comprising a movable support rotating around an axis, and carrying at least one pendulum movable relative to the support. [0006] Due to the presence of the part of the flywheel forming the reaction plate of the clutch, the space available for receiving the damping device is reduced, resulting in placing the device on a smaller radius with respect to the axis of rotation. Such a placement in relation to the pendulum of low weight does not allow...
