Description

field of invention

The invention relates to a vehicle frame, in particular the frame of a railroad car, according to the preamble of claim 1. The frame preferably comprises wheel sets and/or buffers and/or at least one traction mechanism for railroad operations. The invention also relates to a manufacturing method according to claim 11.

Technological background

Railway wagons have been used for years to transport goods by rail. These railroad cars are made of metals or metal alloys.

Iron (Fe) is often used, with welded constructions being used, which are usually very heavy.

So will about in the DE 613 728 C proposed with regard to the frame construction that the frame consists of longitudinal members and cross members and these are designed in box section

Description

Against this background, the object on which the invention is based is to reduce the weight of the vehicle frame.

This object is achieved by a vehicle frame according to claim 1.

Accordingly, it is proposed to produce the vehicle frame, in particular the railroad car, from a material that has a lower specific weight than the common metals, in particular iron.

By reducing the weight of the frame, the transport capacity of the railway wagons is increased and the logistics costs are reduced. Furthermore, the railway wagon can also be used in two-way operation due to its significantly lower dead weight. As a result, further cost advantages can be achieved in logistics, with environmental and sustainability aspects being significantly strengthened.

It is planned that the metal (Fe) frame of the vehicle or railway carriage will be replaced by a material with a lower specific weight, with the frame being able to be produced inexpensively from simple profiles.

The frame of the railroad car is preferably equipped with rail wheel sets, with spring assemblies, with a buffer, with a braking system and with at least one traction device.

The frame is preferably rectangular in shape and comprises longitudinal and transverse profiles. Further refinements result from the dependent claims.

The invention is illustrated below with reference to a drawing in which a vehicle frame is illustrated by way of example.

Detailed description of exemplary embodiments

The 1 until 5 show a railroad car (100) which is equipped with a frame (1) on which permanent buffers (2). a brake system (3), rail wheel sets (4), spring assemblies (5) and traction means (6) are attached.

The frame (1) 2 consists of a vehicle longitudinal side (7) and a frame transverse side (8), the vehicle longitudinal side (7) consisting of several support tubes (9) of the same length, which lie in a horizontal plane (10). The frame transverse side (8) 2 consists of box profiles (11), which are within the railway gauge.

The support tubes (9) 4 and multiple box sections (11) 3 , which are attached along the support tubes (9), form the frame (1) of a railroad car (100).

The frame (1) of the railroad car (100) is designed as a plug connection (101) and consists of a material that is lighter than Fe. In addition, the frame (1) consists in particular of carbon and the connecting means consist in particular of an adhesive.

The support tube (9) is designed with a circumferential pair of grooves (18), with a groove diameter (D) and with a groove spacing (A).

The round bracing (25) 5 is with a circumferential groove (26) and with a groove diameter formed ser (D1) and is at an angle (A) to the box section (11).

Furthermore, the supporting tube (9) is designed with several peripheral pairs of grooves (18) that sit along the longitudinal side (7) of the supporting tube (9) of the vehicle, each of these peripheral pairs of grooves (18) being able to have different groove spacings (A). The shape of the peripheral pairs of grooves (18) can consist of different geometric shapes.

The peripheral pairs of grooves (18) along the longitudinal side (7) of the vehicle are separated from one another by equal or, in particular, different distances. The groove diameters (D) are the same in the individual circumferential pairs of grooves (18), but can vary depending on the size of the individual support tubes (9) in the different circumferential pairs of grooves (18) along the longitudinal side (7) of the vehicle.

All peripheral pairs of grooves (18) of the support tubes (9) have the same or different distances from one another in the frame (1) of the railroad car (100) along the longitudinal side (8) of the vehicle, depending on the function of the frame (1) and are aligned with the transverse side of the frame ( 8th).

The rigid and torsion-resistant box profile (11) consists of flat material and is determined by the box length (12), the box height (13) and the box depth (14). The box section (11) is provided with a plurality of continuous box holes (15), the box holes (15) passing through the box section (11) along the box depth (14) and being perpendicular to the horizontal plane (10). The box profile (11) is divided in the center of the box holes (15) by the horizontal plane (10) into an upper box (16) and a lower box (17).

The box holes (15) can have different diameters, depending on the size of the support tubes (9). The number of box holes (15), the diameter of the box holes (15), the distance between the box holes (15) in the direction of the transverse side of the frame (8) and the distances of the box holes (15) to the edge of the box section (11) in the direction of the transverse side of the frame (8) is determined by the function and the statics of the frame (1).

The upper box (16) and the lower box (17) are preferably made of flat material.

The upper box (16) consists of an upper part, two side parts, two head parts and is made into one component by means of connecting means. The upper box (16) is equipped with stiffeners to increase the flexural and torsional rigidity. The fasteners of the top box (16) are cured in an autoclave.

The lower box (17) consists of a bottom part, two side parts, two head parts and is made into one component by means of connecting means. The lower box (17) is equipped with stiffeners to increase the flexural and torsional rigidity. The lower box (17) fasteners are cured in an autoclave.

The lower boxes (17) are placed along the longitudinal side (7) of the vehicle at equal or different distances from one another, depending on the function of the frame. Then the circumferential pairs of grooves (18) of the support tubes (9) and the circumferential groove (26) of the round reinforcement (25) are inserted into the lower box profiles (17) with the connecting means, so that the support tubes (9) and the round reinforcements (25 ) are locked horizontally.

The rigidity of the frame (1) also depends on the diameter of the support tube (9) and the groove diameter (D) of the pair of grooves (18). The greater this distance, the greater the rigidity of the frame (1). The upper boxes (16) are then inserted into the peripheral pairs of grooves (18) of the support tubes (9) with the connecting means, so that the upper boxes (16) are locked horizontally. In addition, the lower boxes (17) are connected to the upper boxes (16) by a connecting means, in particular epoxy resin.

By inserting the support tubes (9) with the circumferential pairs of grooves (18) in the lower boxes (17) and by inserting the upper boxes (16) in the circumferential pairs of grooves (18) of the support tubes (9), the connecting means create a non detachable connector (101) generated.

The support tubes (9) can be replaced by other profile shapes.

In addition, underneath on both sides of the frame (1) trussed beams (19) are attached to the lower boxes (17) by connecting means, the trussed beams (19) being connected to one another by crossbars (20) in the direction of the transverse side (8) of the frame . A non-detachable connection is created by the connecting means. The flexural rigidity and thus the load-bearing capacity of the frame (1) are increased by the girders (17) under tension.

Furthermore, on both sides below the frame (1) link guides (23) attached to the frame (1) by fasteners. As a result, the rail wheel sets (4) are held in the slotted guides (23) while driving. The rail wheel sets (4) are guided in an up and down movement in the slotted guides (23), with the rail wheel sets (4) transmitting their movements to the spring assemblies (5). The spring packs (5) are attached to the profiles (21) via attachment points (22). In addition, the profiles (21) are fastened under the frame (1) with connecting means and form a non-detachable plug-in connection.

In order to extend the use of the frame (1) for inspection or for transporting goods, floor panels (24), preferably made of carbon, are attached to the upper boxes (16) of the box sections (11) of the railroad car (100) using fasteners.

After completing the complete frame (1), it is placed in an autoclave for the adhesive to harden.
