Abstract

The invention relates to a base for passenger coaches, which can be found taking into account the dimensional deviations for the essential basic types of passenger coaches application. The goal is to provide a standardization of preferably the middle part of subframes, which even by the Laengenaenderung for the different types of car, for example. Y or. X-car, not broken. The object of the invention is to provide a lower frame of the kind mentioned in the introduction, which considerably simplifies its manufacture and production, facilitates its assembly and reduces its production costs. According to the invention, this object is achieved in that the standard aggregates required for each passenger coach have an arrangement which is essentially constant regardless of the type of car. For the passenger car of the type "X", which is longer in its dimension, it is provided to advantageously additionally arrange two cross-carrier fields in the area of two adjacent, certain cross-carrier fields. This similar cross-tractors field division for the different in their length Y or X-car has the advantage that the standard equipment contained can preferably always be placed in the same place.

Description

Title of the invention: Undercarriage for passenger coach

Field of application of the invention:

The invention relates to a base for passenger coaches, which can be found in compliance with the deviations contained in the UIC / OSJD leaflets for the essential basic types of passenger coaches application.

Characteristic of the known technical solutions:

For undercarriages for rail vehicles, it is generally known to assemble these from a number of subassemblies, for example »stem, middle part, stem. These assemblies can be prefabricated and varied. A known solution according to DE - Pat. 19 19 179 provides for head pieces or stems of the same design by different lengths middle parts to make accordingly lang'e frames, these bases are mainly provided for two-axle freight cars.

The disadvantage of this design is the Hichtanwendbarkeit for passenger coaches, since the possibilities of the arrangement of, for passenger coaches .Inelässliche aggregates was completely disregarded.

Another disadvantage is the non-reference to certain types of cars with internationally defined pivot distances.

Most of the other known technical solutions are concerned with the derivation of the forces occurring at substructures, while leaving the different lengths of the substructures. disregard the questions of the arrangement of "necessary aggregates on the undercarriage"

Object of the invention:

The object of the invention is to provide a standardization, preferably of the middle part of subframes for passenger coaches, which is not broken even by the change in length of the undercarriage for the different types of car, eg. Y- or X ~ car, and thus the defects of the state eliminated the technique

Explanation of the essence of the invention:

The object of the invention is to provide a subframe for passenger coaches, which, taking into account the deviations contained in the UIC / OSShd leaflets for the basic types of passenger coaches is substantially unified and which can be used both for Y-car, as well as for X-cars which considerably simplifies its manufacture and production, facilitates its assembly and reduces its production costs,

According to the invention, this object is achieved in that the required for each passenger car standard aggregates, such as underfloor - heating unit, battery boxes, steam inlet regulator and dgli have an independent of the Wagenbauart substantially constant arrangement in the between the two main cross members systematically, preferably symmetrically arranged cross member fields. , ,

"" 3 "

In order to be able to use the undercarriage, as it is, for example, for a passenger coach of the "Y" type, also in principle for a touring coach of the "X" type, it is preferable to have two additional ones according to a further feature Crossbeam fields of the same size on both sides of the center of the car, advantageously in the region of two adjacent, certain crossbeam panels for the purpose of its extension for the passenger car in its dimensions de 's type "X" are arranged.

This similarly designed cross beam field pitch for the different types of cars, i. Y- and X-cars offers the advantage that the standard equipment contained in each passenger car, based either on the center car in the transverse direction or on the center of the main cross member, both the shorter Y-car. as well as with the longer X-car preferably always in the same place can be arranged.

All other devices and fittings required for the operational and traffic safety of the passenger carriages, which are installed in the undercarriage, are arranged so that they do not affect the uniform crossbar system. In the X-carriage additional two cross member fields an arrangement of the devices, for example. For air conditioning or other wagenbauartspezifische aggregates, provided.

Embodiment:

In the drawings, an exemplary embodiment of the division of the cross-member panels and the arrangement of the aggregates is shown in a clear manner.

Pig. 1: top view of a subframe of the Y-carriage with arrangement of the standard aggregates or fittings; Fig. 2: Top view of a base of the X-carriage with. Arrangement of standard units or fittings.

As shown in Fig. 1, there is the base of the Y-carriage

from the two stems A and B and the middle part, which is divided into a plurality of cross member fields a _f b, c, d, e, f, wherein like designations represent cross member fields of the same size. The arrangement of the cross beam fields is symmetrical, based on the center carriage in the transverse direction.

In these cross member fields all required for a passenger coach units or »fittings are arranged schematically. According to the invention thus the underfloor heating unit 1 in the middle of the car in the transverse direction, the battery boxes 2, the steam inlet regulator 3 when using a steam heating, the main fittings 4 of the pneumatic brake equipment in the same cross member fields, based on center carriage arranged transversely. The rectifier boxes 5, the fuse box 6, the mechanical part 7 of the brake system and the fittings of the pneumatic part of the door closing device 8, based on the center main cross member 0 arranged

As in Pig. 2, the undercarriage of the Y-carriage consists of the two stems C and D and the central part, which has the same crossbeam fields as the undercarriage, the Y-carriage and which has only been supplemented by the two additional crossmember fields g * Also in this Underframe takes place the arrangement of the cross beam fields symmetrically, based on the center carriage in the transverse direction * The arrangement schematically shown required for coaches units or fittings remains unaffected by the additional cross-member fields g.

Claims (2)

Invention claims: 1. Base for passenger coaches, which, taking account of the deviations in the basic types of passenger coaches contained in the UIC / OSShd leaflets, is essentially unified , is light, characterized in that the required for each passenger coach standard units, such as underfloor heating unit (1), battery box (2), Dampfeinlaßregier (3), main valves (4) for the pneumatic part of the compressed air brake, rectifier boxes (5 ), Fuse box (6), the mechanical part (7) of the compressed air brake, as well as fittings (8) of the pneumatic part of the door closing device, regardless of the type of carriage substantially constant arrangement in the between the two main cross members (0) systematically, preferably symmetrically ordered cross-beam fields (afa) have. 2. Undercarriage according to item 1, characterized in that preferably two additional cross member fields (g) of the same size on both sides of the center car, advantageously in the region of two adjacent, eg.
