Description

To activate the brake pads in the event of a train breaking, the brake brake connected to them, composed of two articulated parts, is pressed at the point of its articulation from the load eccentrically suspended on a fixed axle. In the rest position, the load is held in a raised position by a dog, the disengagement of which with the load, under the influence of tension due to breakage of the composition, is accompanied by lowering the load and tension of the brake pull due to its bending in the hinge.

In the drawing, FIG. 1 is a schematic side view of this device; FIG. 2 is a side view of the undercarriage chassis fitted with this fixture.

The braking device for a train breakage consists of an eccentric, suspended on a fixed axis to the frame of the carriage cargo 5, supported in a raised position by a pivoting dog b, the upper end of which is connected to the flexible link 8 running along the train or part of the carriages. On the side opposite to the wheel of the car, the load 5 is supported by the end of the pivoting lever 2, the free arm of which moves along the guide 1 and is connected to the end of the brake

ti 3. Tg 3 consists of two parts connected to each other by a hinge located under load 5, so that if the load is lowered, the associated finger 9 is lowered onto the hinge, and when the load is not in working position, both parts of the pull 3 are one straight line under the action of the spring 10. A hibber strengthens a squib, with which finger 9 can come into contact when lowering the weight 5. The opposite end of the string 3 is connected by means of strings 4, which control the pressing of the pad on the wheel. In addition to the finger 9, the load 5 is provided with another finger carrying a brake shoe 11, designed to come into contact with the wheel band when lowering the load.

In the event of a break in the bending composition, the ha 8 moves the upper end of the dog b to the left in FIG. 1 and releases its lower end from engaging with the load 5, which causes rotation and lowering of the load 5. Finger 9 causes an explosion of the squib on the hinge of the rod 3 and bends this tie in its hinge joint, which is accompanied by pressing the pad on the wheel while simultaneously pressing the pad 11 to the other side of the wheel. Upon additional braking of the train with hand brakes, after the load drops 5, the ton ha 3 straightens out pressure from the pads on it and turns lever 2

In a position that lifts the load 5 upwards, it clings to the dog 6 again. When the load 5 is in the bridged position with the dog, the braking is performed by a hand brake, which does not affect the brake load 5, since the end of the lever 2 is case passes without hitting the cargo 5.

The subject matter of the invention.

1. A device for braking wagons at train rupture, characterized in that a load 5 applied eccentrically suspended on a fixed axle and held in a charged state by a pawl 6 discharged at break is applied to the braking system.

trains running along the train (or part of the cars) flexible.

2. The form of implementation of the specified VP. 1 device, characterized in that in order to influence the load on the brake cable 3, the load is provided with a finger 9.

3. The form of implementation of the device specified in paragraphs 1 and 2, characterized in that for additional braking the load 5 is provided with a brake shoe 11 designed to come in contact with the bandage of the wagon wheel when the load is rotated into the working position.

4 Application with the device specified in paragraphs 1-3, posted on 3 fireworks, exploding, for the purpose of a sound signal, when the load 5 is rotated into the working position from hitting the finger indicated in paragraph 2.
