Rotary bearing for wheel of e.g. passenger car, has measuring rod facing sensor that is connected with inner ring in torque-proof manner for measuring rotation of wheel of motor vehicle, where sensor is secured in recess in inner ring

摘要

The bearing has an outer ring rotatable opposite to an inner ring (1), and a bearing inner space formed between the rings. A cassette gasket (2) has a ring-shaped measuring rod (11) connected with the outer ring in a torque-proof manner. The measuring rod faces a sensor (13) that is connected with the inner ring in a torque-proof manner for measuring rotation of a wheel of a motor vehicle. The sensor is secured in a recess (12) in the inner ring. The sensor is designed as a moisture sensor for measuring moisture in the bearing inner space.
