Mounting system of a pneumatic module and of an electrical module, in a coupler head of a goods wagon

1 . A mounting system of a pneumatic module and of an electrical module, in a coupler head of a goods wagon, the mounting system comprising:

a carriage which incorporates the electrical module, the pneumatic module and a shut off valve;

wherein the carriage is structurally arranged to allow guided elastic movement in a direction paraxial to that of a longitudinal axis of the coupler head and is further structurally arranged to allow a limited, guided and elastic movement path, in the direction of a vertical axis and of a horizontal axis, said vertical and horizontal axes being comprised in a plane transverse to the longitudinal axis of the coupler head, to establish a floating elastic mount of the carriage in three axes perpendicular to each other, which allows the relative movement between the pneumatic and electrical connection modules, with respect to the coupler head.

2 . The mounting system of claim 1 , wherein the carriage further comprises springs which establish a pushing force in the direction paraxial to that of the longitudinal axis of the coupler head, to take the carriage to an approaching position with respect to a carriage of an adjacent wagon, in the coupling of both wagons.

3 . The mounting system of claim 2 , wherein in relation to a front portion of the carriage, a latch is arranged that retains the mobile carriage against the action of preloaded springs; and

wherein the latch releases the carriage, the coupling between the coupler heads of the two wagons takes place.

4 . The mounting system of claim 1 , further comprising a tensor element which on one end is integrated with the rotation shaft of the mechanism of the coupler head, and on the opposite end is coupled to the carriage; and

wherein, when the uncoupling between two wagons is established, the tensor element, pulls the carriage moving it in the retraction direction, opposite to the direction of approach, to disconnect the connections of the pneumatic and electrical modules.

5 . The mounting system of claim 4 , wherein the tensor element runs through a pulley, mounted on a support comprising a pivoting connecting rod, with elastic means that maintain the tension of the tensor element in all positions of the movement.

6 . The mounting system of claim 4 , wherein the tensor element comprises a cable or chain.

7 . The mounting system of claim 1 , wherein the shut-off valve is connected to a brake pipe of the wagon and defines three chambers therein, with a tappet that a spring maintains in a closed position; and

wherein the shut-off valve incorporates a retention element which maintains the tappet in an open position, against the action of the spring, such that in the coupling between two wagons, the tappet of each valve is put in the open position, wherein it is retained by the retention element, thereby allowing air to pass.

8 . The mounting system of claim 7 , wherein the retaining element of the tappet is coupled to a rocker arm which, when the carriage moves in the retraction direction, swings and removes the retaining element, so that the tappet is released and returns to the initial position thereof, closing the passage of air, thereby preventing the air in the pipe of the vehicle from escaping into the atmosphere.

9 . The mounting system of claim 8 , wherein the central chamber of the valve is connected to an outlet conduit, wherein, on the condition of a failure in the mechanical coupling and the physical connection between wagons is interrupted, the retention element maintains the tappet in an open position, against the action of the spring, such that the air exits to the atmosphere through the outlet conduit.

10 . The mounting system of claim 8 , wherein:

the carriage incorporates a head mounted on an axis related to a connecting rod having a cam associated to a ratchet mechanism;

wherein the ratchet mechanism establishes that, when the carriage moves in the direction of approach, the cam does not act on the connecting rod;

wherein when the carriage performs the retraction movement, the cam actuates on the connecting rod, thereby causing the head to move in the direction opposite to that of the carriage;

wherein when in the approaching movement, the head impacts against the rocker arm of the retention element of the valve of the opposite coupler, removing the interlocking of the retention element and allowing the valve to return to the closed position thereof; and

wherein when in the retraction movement, the head moves in the direction opposite to the valve, to actuate the rocker arm of the valve of the opposite coupler, such that, by actuating on the coupler of a wagon, the valves of the actuated coupler and the opposite coupler shut off.

11 . The mounting system of claim 1 , wherein the carriage is mounted on guide shafts of a guide frame, and wherein the guide frame is mounted on a pair of guide parts integral to the coupler head between wagons;

wherein the guide parts allow limited movement of the frame vertically and horizontally and with it, limited movement of the carriage.

12 . The mounting system of claim 11 , wherein each guide part comprises first elastic means arranged according to a vertical axis, and second elastic means arranged according to a horizontal axis which maintains the carriage in a stable position centred in both vertical and horizontal directions and allowing the elastic floating play thereof.

13 . The mounting system of claim 1 , further comprising, at the front of the carriage, a protruding male centring element having a conical or rounded head, and a female receiver with conical inlet and cylindrical hollow end, for centering between the pneumatic and electrical connection modules.

14 . The mounting system of claim 1 , wherein the electrical module comprises a keypad which houses the electrical contacts and which comprises a central body, a rear lid, and a mobile cover; and

wherein when the carriage moves in the direction of approach, the mobile cover is pushed by means that lift it towards an open position; and

wherein when the carriage moves in the opposite or retraction direction, elastic means take it to the closed position thereof.
