ABSTRACT:
A current collector shoe suspension for sliding contact with an electric power line in an externally powered electric vehicle. Current collecting shoes are resiliently biased toward a power rail through a plurality of interconnected vibration absorbing units pivotally mounted to the vehicle. Each unit can vibrate independently of the others, and the units have different resonance points so displaced that their vibration characteristic curves overlap, whereby the shoes maintain contact with the rail over a wide range of vibration frequencies and amplitudes.
