Description

The utility model relates to the field of railway transport, and can be used in the construction of non-rigid automatic coupling devices of freight cars.

When performing shunting operations, as well as in the modes of conducting the train, the body of the automatic coupler perceives compressive and tensile loads. With the perception of tensile loads, the body of the automatic coupler through the wedge of the traction clamp transfers the load to the traction clamp and further to the absorbing apparatus. At the same time, when performing work in violation of the requirements of regulatory documents, the jumper of the shank of the auto coupler body takes up significant loads, which can lead to its kink and, thus, breakage of the auto coupler body.

In the field under consideration, various technical solutions for the execution of the body of the automatic coupler are known.

So, a patent is known for utility model RU 157653 (IPC B61G 3/00, published December 10, 2015), according to which the hitch of a railway vehicle consists of a shank characterized by a longitudinal axis located in its plane of symmetry and a head part containing a large tooth characterized by a longitudinal axis located in its plane of symmetry, and the tooth is small, as well as the adhesion mechanism located between the large and small teeth. The longitudinal axis of the shank is offset in the vertical direction relative to the longitudinal axis of the tooth of the large head part.

A patent for invention RU 2519560 (IPC B61G 3/12, published on 06/10/2014) is known, according to which the automatic coupling case of a railway vehicle is made in the form of a hollow casting consisting of a head part and a shank in which the width of the crescent tide located in the head pocket parts, does not exceed the wall thickness of the lock at the location of the fuse rod.

Also known is a patent for the invention RU 2381933 (IPC B61G 3/00, publ. 02.20.2010), according to which the hitch of a railway vehicle is made in the form of a hollow casting and contains a shank with stiffeners located on horizontal shelves, turning into a head having a large and small teeth in its front part and the back wall provided with an external stop. A vertically located reinforcing rib is made on the inner surface of the dorsal wall of the head.

Known typical automatic coupling SA-3, which is the closest in the set of essential features to the proposed utility model, and is selected as a prototype. The specified automatic coupling consists of a shank and a head part having large and small teeth with the formation of a pharynx, from which the details of the clutch mechanism protrude - a lock and a lock holder. The shank has a constant height along the length and is made with an opening to accommodate the wedge of the traction clamp, between the rear wall of which and the end of the shank, a shank jumper is formed (see Wagons: design, theory and calculation / Ed. By L. A. Shadur. M .: Transport , 1980). The width L of the jumper of the shank is 0.38 of the height H of the shank.

A common disadvantage of the above known solutions is the presence of high stresses in the area of the liner of the shank when a tensile load is applied.

The technical problem that this real utility model is aimed at is the insufficient reliability of the automatic coupling of a railway vehicle. The proposed solution is aimed at creating an automatic coupler of a railway vehicle of improved design, which allows to reduce stresses in the area of the liner of the liner under the application of a tensile load.

The technical result of the proposed utility model is to improve the technical characteristics of the automatic coupler of a railway vehicle, namely, to increase its reliability by reducing stresses in the area of the liner of the liner under the application of a tensile load, thereby eliminating the disadvantages of the known solutions.

The technical result according to this utility model is achieved by the fact that in an automatic coupler housing containing a shank and a head part consisting of large and small teeth, which, with their outline and the space between them, form a pharynx in which there is a pocket for installing the clutch mechanism, in the shank of which there is the hole for installing the wedge of the traction clamp with the formation of a jumper between the rear wall of the hole and the end of the shank, according to a utility model, the width L of the jumper of the shank is from 0.5 to 1.0 from the height H of the shank.

The proposed design of a railway vehicle automatic coupler, through the use of the proposed ratio of the liner width and height of the liner, reduces stresses in the liner area of the liner when a tensile load is applied due to the fact that due to the design of the automatic coupler housing according to the present utility model compared to the currently used automatic couplers the cross-sectional area of the shank increases. Consequently, its ability to perceive increased tensile loads acting on it through the wedge of the traction clamp increases.

The essence of the proposed utility model is illustrated by a figure, which shows a general view of the automatic coupler, which shows the following components:

1 - shank;

2 - head part;

3 - a large tooth;

4 - a small tooth;

5 - hole for installing the wedge of the traction clamp;

6 - liner jumper;

7 - end face of the shank;

L is the width of the jumper of the shank;

H is the height of the shank.

The body of the automatic coupler consists of a shank 1 and a head part 2, consisting of large 3 and small 4 teeth, which, with their outline and the space between them, form the pharynx of the body of the automatic coupler, in which the pocket (internal cavity) is located for installing the clutch mechanism.

The shank 1 is made with a constant height N. The shank 1 has a hole 5 for installing the wedge of the traction clamp. A jumper 6 is formed between the rear wall 5.1 of the hole 5 and the end face 7 of the shank 1. The ratio of the width L of the jumper 6 of the shank 1 to the height H of the shank is from 0.5 to 1.0.

In preferred embodiments, the ratio of the width L of the liner 6 of the liner to the height H of the liner can be, in particular, between 0.6 and 1.0, preferably between 0.7 and 1.0, and most preferably between 0.8 and 1,0.

Due to the increase in the ratio between the width of the liner of the liner and the height H of the liner, the cross-sectional area of the liner of the liner is increased compared to the known analogues, which leads to a decrease in stresses in the area of the liner of the liner when applying tensile load when performing shunting operations, as well as in train driving modes. This ratio is chosen experimentally, taking into account the imposed restrictions on the connecting dimensions. The range of preferred shank heights H ranges from 135 to 166 mm.

Thus, the proposed automatic coupling of a railway vehicle has improved technical characteristics, compared with the known structures.
