Abstract
Apparatus for detecting a parameter associated with the torque transmitted by a friction clutch, where the friction clutch has a clutch disk which is or can be connected for rotation in common to a power takeoff shaft. The apparatus includes a receiver area (58), which does not rotate with the clutch disk in the torque-transmitting state, and a code provided on the clutch disk. The which code can be scanned by the receiver area and thus generates a sensor signal associated with transmitted torque.
Claims16
An apparatus for detecting torque transmitted by a friction clutch, said apparatus comprising:
- a clutch disk which can be connected to a power take-off shaft for rotation in common with said shaft;
- a code arranged on the clutch disk;
- and
- a receiver area which does not rotate with said clutch disk in a torque-transmitting state, said receiver area being arranged to scan said code and generate a signal associated with the torque transmitted.
An apparatus as in 3 wherein clutch release mechanism comprises a piston and a cylinder, said cylinder comprising said stationary component.
An apparatus for detecting wear which occurs in a friction clutch, said apparatus comprising:
- a clutch disk which can be connected to a power take-off shaft for rotation in common with said shaft while being axially movable with respect to said shaft;
- a code arranged on the clutch disk;
- and
- a receiver area which does not rotate with said clutch disk in a torque-transmitting state, said receiver being arranged to scan said code and generate a signal associated with at least one of the axial position and the axial displacement of the clutch disk.
An friction clutch comprising:
- a clutch disk which can be connected to a power take-off shaft for rotation in common with said shaft;
- a code arranged on the clutch disk;
- and
- a receiver area which does not rotate with said clutch disk in a torque-transmitting state, said receiver being arranged to scan said code and generate a signal associated with the torque transmitted.
A friction clutch comprising:
- a clutch disk which can be connected to a power take-off shaft for rotation in common with said shaft while being axially movable with respect to said shaft;
- a code arranged on the clutch disk;
- and
- a receiver area which does not rotate with said clutch disk in a torque-transmitting state, said receiver area being arranged to scan said code and generate a signal associated with at least one of the axial position and the axial displacement of the clutch disk.
