  • Measurement of torque uniformity in multiplate clutches
    Patent number: 8225650
    Abstract: The invention relates to a method for measuring the uniformity of the moments of shiftable friction clutch systems, the individual friction clutch system comprising an adapter at the input end and at least one adapter at the output end, as well as a system for measuring the uniformity of the moments of shiftable friction clutch systems. According to the invention, the friction clutch system is inserted into a measuring apparatus encompassing at least one moment measuring device. The clutch plates that transmit the driving power in a frictionally engaged manner are pressed against each other by means of a test force. The driving motor is driven at a certain test speed. The torque of the driving motor transmitted by means of the friction clutch system is measured within a certain interval with the aid of the moment measuring device.

  • PLATE FOR A FRICTIONALLY ACTING DEVICE AND FRICTIONALLY ACTING DEVICE HAVING A PLATE OF SAID TYPE
    Publication number: 20110147158
    Abstract: The present invention relates to a plate for a frictionally acting device, which plate can be rotationally fixedly connected, preferably in a positively locking manner, to a plate carrier. According to the invention, the plate is designed so as to be elastically deformable or resilient in the axial direction. The present invention also relates to a frictionally acting device having a plate of said type.
