Problems solved by technology

[0003] In the designs known from the prior art, it has been found that the dual clutches implemented are either relatively complex and bulky, or that, when the encoder part is arranged on the side of the dual mass flywheel outside the dual clutch, this leads to generation of unreliable measurement data

Embodiment Construction

[0031] exist figure 1 In the diagram, the basic structure of the multiple clutch 1 according to the invention can be seen particularly clearly initially. In the exemplary embodiment, the multiple clutch 1 is realized as a double clutch; according to other embodiments, it is also designed as a triple clutch. The multiple clutch 1 has a first clutch 2 and a second clutch 3 . Viewed along the torque transfer path achieved during operation, the two clutches 2 and 3 are inserted between the output shaft of the internal combustion engine (not shown here for clarity) and the transmission input shaft 25a, 25b of the transmission (for clarity not shown in more detail). Thus, the multiple clutch 1 is part of the drivetrain of the motor vehicle during operation. In a preferred embodiment, as figure 1 As shown by the dashed line in , the multiple clutch 1 is operatively connected to the dual mass flywheel 22 . Then, during operation, between the output shaft of the internal combustio...

Abstract

The invention relates to a multiple clutch (1) for a drivetrain of a motor vehicle, having a first clutch (2) and a second clutch (3), wherein each clutch (2, 3) has a first clutch component (4a, 4b)and a second clutch component (5a, 5b) which is selectively rotationally connectable to the first clutch component (4a, 4b), and having an encoder part (8) which has a rotational speed and / or rotational position detection geometry (6) and which is operatively connected to a sensor (7), wherein the encoder part (8) is used as a connecting element (8) which rotationally conjointly connects the firstclutch component (4a) of the first clutch (2) to the first clutch component (4b) of the second clutch (3). The invention also relates to a clutch arrangement (21) having a multiple clutch (1) and having a dual-mass flywheel (22).

Description

technical field [0001] The present invention relates to a dual clutch for use in a driveline of a motor vehicle, such as an automobile, truck, bus or other commercial vehicle, the dual clutch having: a first clutch and a second clutch, wherein each clutch (first clutch and The second clutch (both) has a first clutch member, and optionally has a second clutch member rotatably connected to the first clutch member; and an encoder portion, which is operatively connected to the sensor and has a rotating Speed ​​and / or rotational position sensing geometry. The invention also relates to a clutch arrangement with such a dual clutch and a dual mass flywheel. Background technique [0002] The general prior art is known, for example, from DE 10 2017 102 733 A1. Therein a torque transmission device having a drive ring is disclosed. Therefore, the drive ring is part of the flywheel. [0003] In the designs known from the prior art, it has been found that the dual clutches implemented...
