Description

Devices for automatically, in the event of a wheel axle or similar accidents, braking a train equipped with aerial auto brakes, including a device linking the axle with the air braking system, are generally known. In the proposed device for implementing this connection, a cylinder with a piston is attached to the car body, the rod of which is connected to a special collar worn on the axle of the car, while the piston itself communicates through the corresponding holes in the cylinder wall with the atmosphere, the required inhibition.

In FIG. 1 shows the arrangement in the car of the device proposed with a partial section thereof, and FIG. 2 - one of the details.

Above the wheel axle, under the body of the car, cylinder 7 is fixed, connected by pipe 10 with air brake line 8 and separated from the latter by crane 9, cylinder opening 75, which is released into the atmosphere, is blocked by a cylindrical slide (piston) 2 in normal condition of the axis. By means of a shaft 14, the length of which is adjusted by the screw coupling 7, the piston is pivotally connected to the collar 5 enclosing the carriage (375)

axle axis. For possible reduction of the friction of the collar on the axle, it is immersed in the oil bath 77. Both parts of the collar are interconnected by a spring 4 (Fig. 2), which has a dual purpose: first, to compensate for the car body play about the axes, and second, prevent an excessive rise of the piston 2 under air pressure in order to prevent air from escaping into the atmosphere during normal train travel.

In the event of a breakdown of the axle neck or any other accident in which the car body is left, the piston 2 in the cylinder 7 under the action of the rod 14 raises and opens the opening 75 through which air will leave the cylinder 7 and from the main 8 to the atmosphere, thus making the train freeze. In order to hold the piston in the raised position, a valve 5 is applied, which, under the action of a spring, drops into a circular grinding 6 in the piston.

The tube 72 serves to pass the lubricant into the cylinder.

The subject matter of the invention.

1. A device for braking a train equipped with aerial auto brakes in case of accidents with one of the train car axles, in which the device part of the mechanism, coupled with the axle, controls the train brake through an appropriate device, characterized in that part of the device, coupled with the axle, and the train brake is a cylinder 7 attached to the car body (Fig. 1), the cavity of which communicates with the main air duct and the atmospheric orifice 13 in it.

in the normal state, the carriage shaft axis is blocked by a piston fixed on the rod 14, which is rotatably connected with the shaft. 2. The form of the device according to claim 1, characterized in that the connection of the rod 14 with the axis is carried out by such a collar, parts of which, in order to compensate for the play of the body relative to the axes, are interconnected by a spring 4 (Fig. 2).
