Abstract
Improvements in pantographs for electric traction railway vehicles, this pantograph comprising a static elevation structure on which there is, mounted through an elastic suspension, a pick-up arch in contact with a catenary that may present variations in height along its path of great amplitude corresponding to the passage of tunnels and level crossings and the periodic variations of height due to the catenary itself, being linked to static structure to damping means, characterized in that the tension of the suspension of the capture arch has a value k less than 1 kg/cm and the cushion coefficient c of the shock absorber has a value between 0.2 and 0.8 k, representing k in kg/cm and c in kgs/cm.
