Definitions

- the spacer device cooperates with the sensor friction elements and the friction lining halves such that the sensor friction elements and the friction lining halves define a total thickness that corresponds to the new state of the clutch disk device.
- the sensor friction surfaces occurs as a result of the clutch elements coming into abutment in the operation of the clutch disk device as well as on the friction surfaces of the friction lining halves.
- a preferred embodiment of the clutch disc device is characterized in that the sensor friction surfaces are each arranged in the same plane as the friction surface of the associated Reibbelag half.
- the sensor friction surfaces and the friction surfaces of the friction lining halves are each in a common plane of contact for the Kupplungsele- arranged.
- the coupling elements are preferably a flywheel and a pressure plate of a coupling device.
- Another preferred exemplary embodiment of the clutch disk device is characterized in that the sensor friction elements and the associated friction lining halves are each supported on a common support element in the axial direction.
- the support element is preferably a pad spring device or a ramp device, in particular a counter-ramp ring.
- a further preferred embodiment of the clutch disc device is characterized in that the sensor friction elements are round or partially rounded and held in each case a recess which is provided in the associated friction lining half.
- the recess is preferably slightly larger than the associated sensor friction element and preferably has the shape of a slot. This ensures that the sensor friction elements can move in the associated recesses and in particular rotate.
- a further preferred embodiment of the clutch disc device is characterized in that the sensor friction elements are rotatably arranged and guided in the associated recesses so that they rotate in the associated recesses when the coupling elements come to rest against the sensor friction surfaces of the sensor elements.
- the sensor friction elements in train and shoe operation of a coupling device equipped with the clutch disk device rotate or move in opposite directions.

- the annular surface preferably comprises a plurality of friction lining elements.
- Another preferred exemplary embodiment of the clutch disk device is characterized in that the sensor friction surfaces of the sensor friction elements extend out of the annular surfaces or friction surfaces delimited by the associated friction lining halves.
- the sensor friction elements may extend radially inwardly and / or radially outwardly from the associated annular surface or friction surface.
- a further preferred exemplary embodiment of the clutch disk device is characterized in that the sensor friction surfaces of the sensor friction elements extend radially inwards out of the annular surfaces or friction surfaces delimited by the associated friction lining halves. This space can be saved. In addition, the effect of the centrifugal force acting on the sensor friction elements in operation can be exploited in order to position the sensor friction elements in the associated recess.
- a further preferred exemplary embodiment of the clutch disk device is characterized in that the regions of the sensor friction surfaces of the sensor friction elements which are arranged outside the annular surfaces or friction surfaces or recesses bounded by the associated friction lining halves are encompassed by the spacer device.

- a Belagh mutation 6 is adhered, which comprises a plurality of segment-like covering elements.
- the clutch disc 1 comprises a further Belagh defect 7, which is fastened with the interposition of a ramp device 9 on the drive plate 2.
- the ramp device 9 comprises a Verstellrampenring 10, which cooperates with a Gegenrampenring 11.
- the adjusting ramp ring 10 is rotatable relative to the counter-ramp ring 11 and coupled via three tension springs 12, 13, 14, which are mounted in the drive plate 2, with the drive plate 2.
- the Schmidtpenring 11 is rotatably by leaf springs 16, 17, but limited in the axial direction displaceable, connected to the drive plate 2.
- Belug half 7 is glued.
- the Belaghtren 6, 7 each have a friction surface 19, 20, which is also referred to as an annular surface and in each of which a recess 21, 22 is provided.
- the recesses 21, 22 have the shape of a circular part, from which a circle segment is cut off.
- a sensor friction element 24, 25 is received, which has the shape of a circle which protrudes radially inwardly with a segment of the associated recess 21, 22.
- the sensor friction elements 24, 25 each comprise a metal disk 27, 29, to which a sensor pad pad 28, 30 is glued.

- the sensor friction elements 24, 25 are encompassed externally by the spacer 33.
- the sensor friction surfaces of the sensor mounting pads 28 and 30 are held at a defined distance from one another.
- the metal disk 27 of the sensor friction element 24, like the lining half 6, rests against the lining spring element 3, which is also referred to as a lining spring disk.
