- the pulley 10 of the separating clutch 1 is connected via the belt 1 1 with the motor shaft of the second drive unit 12, which is arranged axially parallel to the axis of rotation 7 of the separating clutch 1, transmitting torque, wherein the pulley 10 with the transmission 38 and a transmission input shaft 39th rotatably connected.
- the pulley 10 has a transmission side 40 and a side facing the first drive unit 2 drive side 41, wherein the torsional vibration damper 4 and the clutch device 9 are arranged on the transmission side 40.
- the pulley 10 extends, starting from the bearing 46 on a flange 49 of the input part 5 facing outwards in the radial direction 13, along the radial direction 13 outwards via the coupling device 9 and the torsional vibration damper 4 to a guide 42 for the belt 1 1.
- the pulley 10 is arranged in the axial direction 20 between the coupling device 9 or the output part 6 and the first drive unit 2.
- the coupling device 9 is designed to be "normally closed”, ie closed in the ground state, in which case the contact force of the friction partners is applied via an actuating element 23 designed as a disk spring a multi-plate clutch 16 shown with an inner basket 17 and an outer basket 18, wherein the outer basket 18 is rotatably attached to the output member 6.
- the inner cage 17 comprises a plurality of bolts 19 which extend through the pulley 10 in an axial direction 20 extending parallel to the axis of rotation 7, wherein a pressure plate 25 is arranged at a first end 21 of the pin 19.
- the actuating element 23 is arranged on the pressure plate 25 and is also supported on a stop 22 on the pulley 10 from.
- a wire ring 50 is disposed between the actuating element 23 and the pressure plate 25, so that the actuating force 28 of the actuating element 23 at an always the same position in the radial direction 13 on the pressure plate 25 is transferable.
- the actuating element 23 is arranged at the first end 21 of the bolt 19, that in the ground state of the coupling device 9, the bolt 19 and thus the pressure plate 25 presses against the pulley 10.
- the disk sets 26 of the coupling device 9 are arranged; wherein by the actuating element 23, the pressure plate 25 with the bolt 19 in a first axial direction 27 is adjustable.
- the bolts 19 are, against an actuating force 28 of the actuating element 23, adjustable by an actuating device 29 via the first end 24 in a second axial direction 30.
- an actuating device 29 can be actuated hydraulically, pneumatically and / or electromechanically.
- the actuating device 29 comprises a release plate 47, via which the plurality of bolts 19 are movable against the actuating force 28 of the actuating element 23 in the second axial direction 30 with respect to the pulley.
- the pressure plate 25 is moved away from the pulley and the plate packs 26 aired.
- leaf springs 32 here is a leaf spring package shown with two leaf springs 32 arranged, which transmit torque from the pulley 10 to the pressure plate 25 (and vice versa).
- FIG. 2 shows the behavior of a leaf spring 32 in the traction mode 33 of the separating clutch 1.
- the leaf spring 32 is arranged at a set-up angle 43 with respect to the circumferential direction 31 between the belt pulley 10 and the pressure plate 25 and extends in the circumferential direction 31 and along the axial direction 20.
- the leaf spring 32 is subjected to tension by a peripheral force acting in the circumferential direction 31.
- a stress on the leaf spring 32 to train causes a reduction of the Aufstellwinkels 43 and an additional, here acting in the first axial direction 27, clamping force 45, through which the pressure plate 25 is pulled against the pulley 10.
- the disk sets 26 of outer basket 18 and inner basket 17 are pressed together even more strongly, so that the torque capacity of the coupling device 9 is increased.
- Fig. 3 shows the behavior of a leaf spring 32 in overrun 48 of the clutch 1.
- overrun 48 only the transmission of the internal combustion engine drag torque (engine brake) is required.
- a circumferential force 44 acts on the leaf spring 32, whereby the installation angle 43 is increased.
- the clamping force acting on the disk packs 26 is thus reduced by an additional clamping force 45 (but now opposite, that is, directed in the second axial direction 30).
