Sensor arrangement for direct measurement of forces and moments acting on bearing box and derivation from these of other values useful in automatic vehicle control systems

摘要

A roller or ball bearing (1) has a sensor arrangement (7, 8) for determination of physical values, such as stresses, while the bearing components are moving. Forces and moments acting on the bearing box (4, 5) are measured and from them stresses acting on the bearing are calculated using an electronic circuit. The invention also relates to a method for analyzing the sensor signals, where the output signals of the sensors are essentially sinusoidal with a frequency dependent on the rotational velocity.
