SU21223A1 - Electric device for automatic braking of air-electric brakes - Google Patents

Description

The proposed device is designed to automatically cause emergency braking when the train leaves the rails, when trains collide, and so on.

In FIG. 1 shows the general scheme of the device; FIG. 2 is a device for causing emergency braking; FIG. 3 is another kind of braking device.

The device is based on the use of a contact device consisting of a load 1 suspended on a spring (Fig. 1), coming in contact with a sudden change in the movement of the wagon, or with the walls of a metal vessel 2 or with a contact plate 4 fixed on the end of the screw 3, adjusting the sensitivity of the device to vertical shocks; The sensitivity of the device to shocks in the horizontal plane is regulated by a screw sleeve 10 (Fig. 1), an insulated load spring 1.

The contact of the load 1 with the plate 4 or with the walls of the vessel 2 causes at the time of closing the circuit using a device consisting of a stationary solenoid 9 (Fig. 1) and a moving core with insulated bottom end of the solenoid 9 during the closing of the circuit and thereby closing, by means of elastic plates 8 (Fig. 1), wires 19 and 20 of the brake system.

A faster and full braking of the vehicle will take place if the proposed device actuates the crane, the driver and automatically sets it in the position of emergency braking using the special tool shown in FIG. 2

The device consists of a burst chuck 15 and a spring piston 13, the rod 14 of which keeps the spring lever 12 from acting on the handle 11 of the driver's crane. In the case of a sharp wagon ride, the device’s device described above closes an additional circuit in which the cartridge 15 is turned on, causes an explosion, and when the stem 14 is lowered, releases the spring lever 12 and turns the driver's handles to the emergency braking position.

The described device, but a more powerful device, can be used to act on the handle of the steam regulator or on the handle of the driver's crane, or both together.

The proposed device for automatic braking can be activated by means of contact buttons 16, 17, 18 (Fig. 3), expediently located in various places of the wagon.
