2. Sliding brush for current collectors of electrical vehicles, whose operational reliability can be monitored by hydraulic fluids. The sliding element contains on its foot side a fluid channel which is manufactured in the following way: a longitudinal groove is milled into the sliding element, the walls of the groove are sealed gas-tightly with an artificial resin, the groove is closed by bonding in a matched, U-shaped longitudinal profile, and a metal tube for the connection to the pressure monitoring system of the pantograph is bonded into an end side, still left open, of the channel formed. <IMAGE> |
