- FIG. 4 shows an inner ring 400, such as inner ring 314 according to FIG. 3, and an outer ring 402, such as outer ring 316 according to FIG. 3, of a second friction module, such as second friction module 300 according to FIG. 3, of a friction device, such as friction device 106 according to FIG 1, in perspective detail view.
- FIG. 5 shows a friction device 500 with a first friction module 502, like first friction module 200 according to FIG. 2, and a second one-part friction module 504, which is arranged so as to be radially displaceable on a driving portion 506 of a double clutch, in a perspective sectional view.
- the friction module 504 has a ring shape.
- the friction module 504 has a radially inner portion 508.
- the radially inner portion 508 serves to form a friction pairing with a radially outer surface of the first friction module 502.
- the radially inner portion 508 has a bevel 512 on the radially inner side on its side facing a driving ring 510.
- the friction module 504 has a runner-like shape on the radially inner side.
- the friction module 504 has a radially outer portion 514.
- the radially outer portion 514 serves to connect the friction module 504 with the driving portion 506 of the double clutch.
- the friction module 504 has a U-shaped cross section with two legs. The legs extend radially outward from the radially inner portion 508. The legs form the radially outer portion 514 of the friction module 504.
- the second friction module 504 is connected with its radially outer portion 514 between the
- the support spring 516 has an annular disk-like shape.
- the support spring 516 is a sheet metal part, for example made of the material C75S.
- An outer diameter of the second friction module 504 is smaller than an inner diameter of a hollow cylindrical portion 306 of a housing 304 of the dual clutch.
- the second friction module 504 in the radial direction relative to the driving ring 510 and the support spring 516 is displaced.
- the legs of the radially outer portion 514 slide on the driving ring 510 and on the support spring 516.
- FIG. 6 shows a second one-piece friction module 600, like second friction module 504 according to FIG. 5, in perspective detail view. development. It can be seen that several intermediate walls, such as 602, are arranged circumferentially between the legs of the radially outer section.
- the second friction module 600 is made of a plastic, for example of PA6.
- the second friction module 600 has a weight of about 180-280 g, in particular of about 230 g.
