Description

The invention relates to the field of rail vehicles and can be used in triangles of brake linkage mounted on the side frames of the undercarriage trolleys.

Known triangel brake system of a railway vehicle for installation on the side frames of the trolley, in which the shoes are mounted with rivets to a beam made from a corner and connected at its ends with a string (see patent US 4830148 A, publ. 16.05.1989).

Known triangel brake lever transmission of a railway vehicle, mounted on the side frames of the trolley, containing a beam made of a corner, and a string separated in the middle part by a spacer and connected at the end parts, on which the brake shoes are mounted, fixed from longitudinal movement along the beam with using rivets, or clamping bolts and crimp bushings (patent RU 171865 U1, publ. 06/19/2017).

A technical problem that cannot be solved by the known suspension-type triangles is the insufficient rigidity of the attachment points of the brake shoes to the triangel beam. Through the mentioned attachment points, the forces arising during braking are transmitted from the shoe to the beam, which requires reinforcement of these places.

The technical result of the utility model is to increase the rigidity of the triangel in the places where the brake shoe shoes are attached to the beam, increase the operational reliability of the brake lever triangel of a railway vehicle.

The technical result is achieved by the fact that in the brake lever triangel of a railway vehicle containing a beam and a string, separated in the middle part by a spacer and connected in the end parts, while the brake shoe shoes are fixed at the ends of the beam made from a corner, according to a utility model, the beam in the places where the brake shoes are attached is equipped with stiffeners.

In a preferred embodiment, the stiffening ribs are fixed to the beam at the attachment points of the brake shoes, corresponding to the longitudinal planes of symmetry of the brake shoes.

In particular forms of realization, stiffeners are fixed by a welded joint.

In private forms of implementation, the brake shoes are fixed to the beam using rivets, or clamp bolts and crimp bushings.

The presence of stiffening ribs on the beam at the points of attachment of the shoes increases the rigidity of the triangel, preventing the formation of deformations of the end parts of the beam and the shoes of the brake pads from the forces arising from the operation of a railway vehicle. Thereby, the weakening of the frictional forces between the brake pads and the wheels of the wheeled trolleys of the railway vehicle is prevented. The installation of one stiffener in a place corresponding to the longitudinal plane of symmetry of the brake shoe is the most appropriate for stiffness and minimal increase in metal consumption.

A utility model is presented in the drawings, where it is shown:

in FIG. 1 - triangel brake linkage, axonometric projection;

in FIG. 2 - triangel beam, axonometric projection.

The brake link triangel (Fig. 1) contains a beam 1 and a string 2, separated in the middle part by a spacer 3 and interconnected in the end parts. Beam 1 is made of a metal corner. At the ends of the beam 1, shoes 4 of brake pads are mounted, fixed to the beam with fixing devices, in particular rivets 5. The ends of the beam 1 are equipped with stiffening ribs 6, which are fixed, for example, by welding, to the shelves of the beam 1.

The stiffening ribs 6 (Fig. 2) are fixed on the beam 1 in the middle between the holes 7, made for the installation of rivets 5, in places corresponding to the longitudinal planes of symmetry of the shoes 4 of the brake pads in the assembly of the brake linkage triangel.

The utility model works as follows.

The brake link triangel with the shoes 4 with brake pads fixed at its ends is mounted on the side frames of the rail vehicle trolley. During braking, the force is transmitted through the shoes 4 to the beam 1 and then to the stiffening ribs 6. The attachment points of the shoes 4 of the brake pads to the beam 1 maintain the integrity of the structure, are not subject to deformation, and the operational reliability of the brake linkage triangles is increased.
