Claim 16:
17. The belt drive as claimed in claim 16, further comprising:
the belt drive comprised in a steering gear of a motor vehicle;
the belt drive has two drive traction belts;
two drive and driven pulleys;
wherein the drive pulleys and the driven pulleys are each continuously connected to one another in a rotationally fixed manner on a common shaft;
wherein both drive traction belts have at least one marking and at least one associated sensor element for detecting the belt markings is respectively provided;
wherein the sensor elements have electronic devices for outputting the signals SR1 and SR2 which are dependent on the detection of the markings;
wherein the rotor of the electric drive motor has at least one rotary encoder or position encoder which can be used to detect the position or speed of the rotor during the motor rotation and to output a signal SM dependent on the position or speed;
wherein a computing unit provided with memories and processors for processing the signals SR1, SR2 and SM, and wherein a temporal or local correlation of the occurrence of the signals SR1, SR2 and SM is calculated in the computing unit when the drive belt is new and is stored as a reference value;
wherein the associated signals SR1, SR2 and SM are then repeatedly determined for further specified belt revolutions or periods of time and their current temporal or local correlation of the occurrence is compared with the reference value.
