Abstract

Improved suspension support device for axle wagons that incorporate a standard suspension system formed by a parabolic spring (1) located on the grease box (2) mounted on the ends of the treads (3), joining each one of the parabolic springs at its ends to an assembly formed by four rings (4) joined by an intermediate bearing (5) and having at the ends of said assembly four ring guides (6) that allow connection with the parabolic spring ( 1) on the one hand and with the suspension support (7) on the other, as well as some suspension axes (8) that allow the unión of such elements placing at their ends some safety stirrups (9) to avoid the possible displacement, said suspension support being formed by two embossed plates welded together forming a drawer at the lower end of which a mousse (11) and a bushing (12) that forms the point of attachment with the ring (4) are welded together. And its guide (6) by the suspension shaft (8) and at its other end is welded to the structure of the frame (10), characterized by providing a new variant to the standard suspension support by the configuration of softer spokes and increasing the thickness of the embossed sheets (13) that form it, which are welded together by a continuous weld bead and at its lower end weld the moyu (11) with the bushing (12).

Description

Enhanced suspension support device for axle wagons

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to a device improved suspension support for axle cars, which has been conceived and carried out in order to obtain important advantages with respect to other existing means of analogous purposes.

The purpose of this utility model is the development of a device that improves suspension support standardized axle cars by two ways or variants that will be explained in the description of the invention.

The present utility model is developed in the mechanical sector of the supporting elements of the suspension in axle cars for freight transport of a railway vehicle.

Background of the invention

At present, all the wagons destined to the transport of goods incorporate a suspension system responsible for absorbing and mitigating the efforts received by the load to transport and by the weight of the car itself.

In the case of axle cars said system of suspension is formed by a parabolic spring located on the grease box which, in turn, is mounted at the ends of the rolling shafts Each of the parabolic docks joins in their ends to a set consisting of four rings joined by an intermediate bearing. At the ends of said set They have four ring guides that allow connection to the parabolic spring on one side and with the suspension bracket on the other. Said system is carried out by means of axes of suspension that allow the union of such elements and in their ends are placed safety stirrups to avoid the possible displacement

In the traditional suspension system described, the suspension support is welded to the structure of the frame and at its end, using a moyu and a bushing, it attaches to the ring guide of said assembly, through which receives the efforts transmitted by the parabolic spring.

Suspension brackets are elements essential within the suspension system of wagons of goods. These supports, together with the parabolic springs, Their mission is to absorb the efforts of the tare and the burden of wagon.

With the present invention it is intended to improve the standard suspension support of axle cars avoiding Critical areas of stress concentration through the provision of a new geometry to the suspension support itself, either welding together the embedded sheets that make it up, either elaborating a unique piece that integrates these plates eliminating, by  So much, its welding.

Description of the invention

A support device has been developed for Improved suspension for axle cars.

The standardized suspension support consists of two embedded plates welded together that form a drawer. On the lower end there is a moyu welded and a bushing that constitutes the point of attachment with the ring and its guide by means of the
suspension.

Through this utility model, aims to improve standardized suspension support by two variants:

Variant 1: To the suspension support already known a new geometry is applied, with softer radii and increasing the thickness of the embedded sheets that form it, thus winning in resistance. These sheets are welded together using a continuous welding bead and at its lower end it  weld the moyu with the cap. The design of said variant allows to avoid critical areas of concentration of tensions.

Variant 2: It consists of a suspension support integral with which, in addition to increasing its resistance, it is achieved Eliminate the welding of the plates when this is a piece unique and it is only necessary to realize the welding of union to the set formed by the moyu and the bushing.

Description of a preferred embodiment

This Utility Model consists of a improved suspension support device for wagons of axes

In order to conveniently describe the present invention we must start from the existence of a system Standard suspension arranged for axle cars intended primarily for the transport of goods. Saying suspension system consists of a parabolic spring (1) located on the grease box (2) which, in turn, is mounted on the ends of the raceways (3). Each of the docks parabolic joins at its ends a set consisting of four rings (4) joined by an intermediate bearing (5). In the ends of said set are arranged four ring guides (6) which allow connection to the parabolic spring (1) on one side and with the suspension support (7) on the other. Said system takes carried out by means of suspension shafts (8) that allow the union of these elements and at their ends are some stirrups of safety (9) to avoid possible displacement.

In the traditional suspension system described, the suspension support (7) is welded to the structure of the frame (10) and at its end, by means of a moyu (11) and a bushing (12), attaches to the ring guide (6) of the aforementioned set, through which it receives the efforts transmitted by the parabolic spring (1).

The standardized suspension bracket (7) is formed by two embedded plates welded together forming a drawer, at whose lower end a moyu (11) and a bushing (12) constituting the point of attachment with the ring (4) and its guide (6) by means of the suspension shaft (8).

Through this utility model, intends to improve the suspension support (7) standard, by two variants:

Variant 1: To the suspension support (7) and known a new geometry is applied, with softer radii and increasing the thickness of the embedded plates (13) that form it, thus winning in resistance. These plates (13) are welded together by a continuous welding bead and at its lower end the moyu (11) is welded with the bushing (12). The design of bliss variant allows to avoid critical areas of concentration of tensions

Variant 2: It consists of a suspension support integral with which, in addition to increasing its resistance, it is achieved Eliminate the welding of the plates when this is a piece unique (14) and it is only necessary to carry out joint welding to the assembly formed by the moyu (11) and the bushing (12).
