Abstract (en)
[origin: WO9856610A1] The invention relates to an improved device for measuring the contact force between a contact wire and a power collector in an electrically powered vehicle, specially an electrical railway vehicle, by means of optical fiber force sensors. To this end, two compact force sensors are arranged between the base body (7) of the wearing strip (6) and the swing-out chassis (7) or between the wearing element (8) and the base body (7) of the wearing strip (6). Each sensor includes a deformable body (11), which is elastic in an axial direction but highly rigid crosswise, said body being fitted with an integrated optical fiber reflex sensor (19). Axial deformations of the deformable body (11) equivalent to the contact force are detected by the reflex sensor (19) with high resolution, accuracy and no interference, are then signalled to a device via optical fibers requiring no potential and converted therein into contact force-equivalent signals (28) or instructions (29).
