PANTOGRAPH WITH A DAMPED HEAD SUSPENSION

摘要

Company called: FAIVELEY TRANSPORT "Pantograph with a damped head suspension" (An invention of: Jacques CATHALA and Pascal FORTE) The pantograph (1) for railroad railcars comprises an upper arm (15), the end of which supports a head (20) for collecting the current from a catenary line (2) suspended via droppers (3) spaced apart over the entire length of said line. This head (20) is connected to the end of the arm (15) via a damped elastic suspension (25) which acts on the high force frequencies to which the pantograph (1) is subjected, in particular on the frequencies when it passes the droppers (3) of the catenary suspension of the line (2). Use in particular, in high-speed railroad traffic. (See Figure 3).
