Embodiment Construction

[0045] In FIG. 1 , a radial section through a motor vehicle friction clutch constructed in a known manner can be seen, a clutch disc 10 is arranged between a flywheel 8 and a pressure cover 9 , wherein by applying an axial pressure force , the compression cover plate 9 establishes a frictional connection between itself, the clutch disc 10 and the flywheel 8 . The components rotate about the axis of rotation 7 ; they are covered by the clutch outer body 15 .

[0046] The clutch disk 10 has a carrier disk 11 on the radially outer region of which a friction lining 1 is fastened by means of a riveted connection 16 . When an axial force is applied, the surface 13 of the flywheel 8 presses against the (left) surface 12 of the friction lining 1 and the (right) surface 12 of the friction lining presses against the surface 14 of the pressure plate 9 .

[0047] Here, the friction lining itself consists of a support element with friction material 3 on both sides. Details here are obtai...

Abstract

The invention relates to a friction lining (1) which is particularly used in a clutch or brake. The invention at least has a supporting element (2), at least one side of the supporting element is provided with a fiction material (3). In order to achieve a firm and non-warping combination, the invention is provided with the supporting element (2) which at least has one circular component or circular segment component (4) winding and extending on the circumference segment of a predetermined friction lining (1); and the radial extending (r) of the supporting element is smaller than that (r)of the fiction material (3), wherein, a plurality of connecting sheets (5), at least one sides of which are wound by the fiction material (3) to form a tongue shape is arranged on the circular component or circular segment component (4); the supporting element (2) is provided with a plurality of fixing segments (6) extending inwards along the axial direction; and the fixing segments extend outwards from the radial direction of the fiction material (3). The invention relates to a friction clutch, in particular to a friction clutch for vehicle.

Description

technical field [0001] The invention relates to a friction lining, in particular for a clutch disk or a brake, which has at least one support element which is equipped with friction material on at least one side. Furthermore, the invention relates to a friction clutch, in particular to a friction clutch for a motor vehicle. Background technique [0002] In such a friction lining, the aim is to have a high strength so that it can be connected as far as possible radially outside the friction surface to a further part of the clutch disk, in particular riveting. In order to achieve high strength, it is known that the friction surface is connected with a reinforced steel plate. When the best possible material connection of a friction material with a steel reinforcement is achieved, the resulting friction lining has a high resistance to bending deformation and can be bonded to a tenon of the friction lining or a The supporting disc of the clutch disc is connected. The friction ...
