Abstract
The invention relates to an apparatus for the protection of a clutch against overheating, specifically a clutch which is located between a combustion motor and a transmission. To ensure protection of the clutch against overheating for most operating conditions, there is an apparatus to determine the drive torque for the determination of the clutch torque or the drive torque transmitted by the clutch, an apparatus for the determination of the slip between the clutch input speed and the clutch output speed, a computer apparatus to determine the product of the clutch or drive torque to be transmitted and the slip, and a monitoring apparatus which combines the value of the product of the clutch torque to be transmitted and the slip with alarm delay times and compares the current slip time with the alarm delay times, and when the alarm delay times are exceeded by the slip times, gives an alarm signal.
