Problems solved by technology

[0004] In addition, the geometry of the pressure plate K1 with connecting plates is difficult in terms of casting technology
Particularly in the transition area in the ring from the web to the pressure plate, porosity and shrinkage cavities can occur due to the diameter difference between the web and the central annulus, which leads to a high number of rejects after processing

Embodiment Construction

[0020] figure 1 The ring body 1 of the multi-part pressure plate is shown.

[0021] Such as figure 1 As is known, the ring body 1 has no webs, so that the casting geometry is simple and the possible rejects are correspondingly greatly reduced. In addition, one obtains the possibility of installing other free or finish-ground or finish-turned outer diameters of the ring body 1 of cast-babbitt metal, whereby very low input unbalances can be achieved.

[0022] After the ring is made into a cast body, the cast body is later (in figure 1 (not visible in ) are fine turned or fine ground in the area of ​​the friction surface. Also, for applications as connecting elements and in figure 2 The abutment face 2 of the angle piece 5 shown in is milled into the ring body 1 or otherwise formed therein. The contact surfaces 2 are arranged on the side of the cast body 1 opposite the friction surface (that is to say the “rear side”).

[0023] According to the present exemplary embodiment...

Abstract

A clutch having a pressure plate (1) and a counter plate (16) is provided, with the pressure plate being displaceable by a clutch actuating mechanism such that a clutch disk can be clamped between the pressure plate and counter plate. The pressure plate is a multi-piece pressure plate having a central body (1) which includes a friction surface and on which at least one connecting element (5) is located, which protrudes beyond the friction surface and is connected to the clutch actuating mechanism for burst optimization and cost savings purposes.

Description

technical field [0001] The invention relates to a clutch having a pressure plate and a counter pressure plate, wherein the pressure plate is displaceable by a clutch actuating mechanism, so that the clutch output plate can be clamped between the pressure plate and the counter pressure plate. Furthermore, the invention relates to a dual clutch having a drive-side partial clutch K1 and a transmission-side partial clutch K2 . Background technique [0002] According to the prior art, the pressure plate of a clutch is cast from a single piece and has a central ring and radially outward webs, via which the pressure plate is connected to the actuation system. Thus, for example, the pressure plate of the drive-side partial clutch K1 of a double clutch has a connecting plate, which is connected (for example riveted) to a rod which is axially displaceable by means of a disc spring / lever spring. [0003] Due to the fact that the webs for riveting the rod extend radially beyond the fri...
