The invention relates to an operating system for inter-communication doors of double deck or single deck passenger carriages, meant to be employed in the railway transports for passengers. According to the invention, the system consists of a supporting and sliding mechanism (A) of two left and right doors (1 and 2), respectively, which is kinematically coupled with a pneumatic cylinder (3) and driven by a pneumatic system (B) interconnected with an electric system (C), the supporting and sliding mechanism (A) having a bar (5) on which there axially slide some bearing boxes (9) for supporting the doors (1 and 2) towards the extreme part and some bearing boxes (10 and 11) for supporting and driving the same towards the middle part, all said bearing boxes (9, 10 and 11) having some linear ball bearings (12), the bearing box (10) driving the left door (1) being kinematically connected to the rod of a pneumatic cylinder (16), as well as to an upper branch (f) of a V-belt (18) by a subassembly (D) for holding and tensioning the belt (18), while the other bearing box (11) driving the right door (2) is fixed to a branch (i) of the V-belt (18), the pneumatic system (B) having the pneumatic cylinder (3) provided with a magnetic piston and two Hall sensors (50 and 51) placed at the ends of the pneumatic cylinder (3) whose signals, together with other signals, are sent to a programmable automaton (F) of the electric system (C). |
