Embodiment Construction

[0035] Figures 1 to 4 A friction disk 1 for a motor vehicle according to a first embodiment of the invention is shown. The friction disk 1 has an axis X and annular friction linings 2 which are located axially on both sides of the support via rivets 3 . The terms "axial" and "radial" are defined with reference to the axis X. The friction disk 1 additionally has two annular guide washers 4 which are fixed to each other via spacers 5 which extend axially and are riveted to said guide washers 4 at their ends. The support is fixed to one of said guide washers 4 via rivets 6 .

[0036] The friction disk 1 additionally has a radial annular web 7 which is positioned axially between the guide washers 4 . The radially inner circumference of the link plate 7 is rotationally coupled to a splined hub 8 which is intended to be rotationally coupled to the input shaft of the gearbox.

[0037] The guide washer 4 is mounted and guided in rotation about the hub 8 via a slide bearing 9 .

Abstract

The invention relates to a friction disc (1), in particular for a motor vehicle, having at least one annular friction lining (2) mounted on a support, characterized in that the support has At least one sector (14), comprising two blade portions (15), each blade portion having a radially outer edge (16) and a radially inner edge (17) connected by a lateral edge (18), each A sector (14) comprising a circumferentially extending connecting region (19), the radially inner edge (17) of each blade portion (15) of said sector (14) is via a radially extending protrusion (20) and attached to the connection area (19).

Description

technical field [0001] The invention relates to a friction disc, in particular to a friction disc for a motor vehicle. Background technique [0002] Clutch devices conventionally have a pressure plate rotationally coupled to a reaction plate with a friction disc mounted therebetween. The pressure plate and the feedback plate are, for example, rotatably coupled to an output shaft of the internal combustion engine, such as a crankshaft. The pressure plate is axially movable relative to the feedback plate between an engaged position in which the feedback plate and pressure plate clamp the friction disc and a disengaged position in which the feedback plate and pressure plate release The friction disc. The friction disc is, for example, rotationally coupled to the input shaft of the gearbox. Thus, in the engaged position, torque is transmitted from the crankshaft of the engine to the output shaft of the gearbox. [0003] Such friction discs usually have an annular support on ...
