Problems solved by technology

As a result of the bending of the central web due to this pressing force, a tilting of the needle bearing, or a one-sided transmission of forces, can occur, so that edge loading of the needle bearing can occur, which undesirably shortens the life of such a needle bearing. service life

Embodiment Construction

[0031] figure 1A double clutch 1 is shown, in which the central web is replaced by a flange 9 in such a way that the pressing force is transmitted by the co-rotating housing 7 . Via an input shaft 2 , the torque is transmitted to the housing 7 and, by engaging the first partial clutch 5 , this torque is transmitted via the first friction plate carrier 12 to the first output shaft 3 . By engaging the second partial clutch 6 , this torque is transmitted via the second disk carrier 13 to the second output shaft 4 . The flange 9 is here formed by a multi-part housing 7 which is connected without play by means of rivets 10 . The dual clutch rotates about a center of rotation 8 , a centrifugal pendulum 11 is arranged radially outside the housing 7 and is located in a wet chamber 24 . On the transmission side, the housing 7 is supported axially against a transmission component 14 (which is only shown here only schematically) and radially against the first output shaft 3 . The firs...

Abstract

The invention relates to a double clutch for releasably connecting an input shaft with two output shafts, the double clutch having a first sub-clutch for connection to a first output shaft and a subclutch for connection to a second output shaft A second sub-clutch, wherein the two sub-clutches are arranged in a rotating housing and through which the pressing forces in the sub-clutches can be received. By means of the dual clutch proposed here, an idle central web is dispensed with, which simplifies the structural design, increases the efficiency of the dual clutch, and makes it possible to largely dispense with heavily loaded, worn needle roller bearings.

Description

technical field [0001] The invention relates to a double clutch for releasably connecting an input shaft and two output shafts, especially for motor vehicles. Background technique [0002] Double clutches are known in the prior art, in which two partial clutches are respectively provided, which are each connected to a separate output shaft. These output shafts are usually each connected to a part of the double-shift transmission, so that when the previous gear ratio is to be changed, the corresponding desired gear ratio (gear) can already be engaged. With the aid of such a dual clutch, shifting times can thus be made particularly short and a torque drop at the output shaft of the drive unit can be avoided. Dual clutches of the prior art are characterized in that they have a central web which is an annular disk which is arranged between the associated partial clutch and receives the corresponding pressing force. To solve this task, the central link must be constructed suffi...
