Force measuring device has connecting means (38) for connecting end horns (30) with the base body (32). Fiber Bragg-grating sensor (41) is arranged in or on the connecting means and is formed as optical extension sensor. The connecting means can be deformed under the effect of the lateral guiding force. The fiber Bragg-grating sensor can be deformed relative to the lateral guiding force of the connecting means. Supply means are provided for supply of the light signal (LS) with predetermined wavelength content. Evaluation means (45) are provided for the determination of the measured value (M1,M2) for the lateral guiding force of the light signal accumulated from the fiber Bragg-grating sensor. An INDEPENDENT CLAIM is also included for the method for determining lateral guiding force between contact wire of overhead line and current collector wearing strip, carried out by base body, wearing element and two end horns of driven rail vehicle. |
