Braking and/or clamping device with monitoring of operational state

摘要

The device has external energy transmissions for loading and relieving the friction pad in loading and unloading direction by actuator or by spring system comprising a spring element which is movable. The adjoining portions (70) of the device housing (10) or in the apparatus built-portion of the surface zones (76,78), expand, compress or twist upon the application of braking and/or clamping force. The strain gauges (85,86) are arranged in the deformable surface zones.
