DESCRIPTION

The invention relates to a bogie for different gauges of railroad tracks. The development of rail transport is due to the presence of various Gauge impaired.

When changing rail vehicles from one gauge As is well known, their landing gear is changed to another one. This is easiest with rail vehicles with bogies, however, it has the following disadvantages. Any two-track vehicle must have two sets of bogies one of which is installed under the vehicle and the other is unused in the transfer station. Also must A transfer reserve of bogies should be available to compensate for the difference in the number of bogies in one direction or the other to compensate for passing vehicles. The transport organization z \ tfischen zv / ei railway administrations requires the Construction of transfer stations with long tracks of both types, with devices for lifting the trains with intended for this purpose Jobs and a number of other devices required for replacement. The amount of work involved is great large and the bogie change a tedious, several hours of work. Particularly difficult and uncomfortably slow the exchange of bogies of the V / agen of a passenger train, for which the bogie storage system itself takes place is not useful.

There are many constructive solutions known in which the chassis of the vehicles is not changed, but the wheels of each set of wheels are precisely defined, the two different ones Lane widths corresponding distances can be shifted. In these two positions the wheels become more complicated by means of mechanisms Construction locked in a gauge change facility

of the tracks under the influence of an external command unlock the wheels, move them to a new position required for the new track width and lock them again.

Due to their great complexity and their weight, this type of wheelset is also used in practice when the relatively easy task to operate two different gauges not applied.

With a small number of articulated carriages with a special one Under the coupling hinge of each car body, the chassis becomes a single-axle bogie guided by the front car attached, in which both wheels are independently supported by two bushes on short axles directly to each wheel. the Bushings are located in cylindrical bores in a body common to both wheels. The wheel bushing set can be between two end positions corresponding to the gauges are moved in the transverse direction and locked in them by means of bolts are pulled out in a transition section downwards be, whereby an inevitable lateral displacement of the wheels and bushings comes about. After that, the Latches pulled up, standing on the other side of the cans. In the gauging system, the load is from the side attached slide rails added. The wheels and bearings are relieved to allow easier lateral movement allow.

The described system with the use of independent running wheels is successful in express trains between two countries applied with different gauge. However, it is only applicable to a specially equipped vehicle fleet, whose carriages are articulated, have single-axle bogies, have brakes on each wheel and are lightweight. For operation requires more extensive maintenance. The two wheels also have a common body because of the load transfer in the re-gauging track through lateral slide rails

909811/0258

quite complicated shape. Furthermore, the four bearings of the two independent wheels must be arranged in the body and it must there should be enough space for them to move sideways.

In order to allow access to the internal bearings, the connecting body must be bent upwards in the middle. This makes the body complicated and very heavy, which limits its use in heavier vehicles since it is too heavy to use belongs to unsprung parts.

Holding the cans in another body prevents them from being observed and the bearings from being properly cooled. It is impossible or very difficult to attach various brake regulators, odometers, speedometers, generator-reduction gears to these bushings zsw. to attach. The fixation of the cans on one side or the other limits the application of this solution on two gauges that differ greatly in width. In practice, this solution is only used in such cases. For heavy vehicles with larger (more voluminous) rifles, this solution is also suitable for widely differing track widths not applicable.

Technical solutions for transport on railway tracks with more than two gauges are not known.

The object of the invention is to eliminate the above-mentioned disadvantages, by creating a bogie that allows for quick, safe and convenient re-gauging of moving rail vehicles between normal and wide gauges of any kind without changing without manual work and without special locking mechanisms provided for this purpose. The re-gauging is not dependent and limited on the mass of the vehicle. You get a simple, easy and clear construction, a possibility of coupling various types of apparatus to the wheel sets, a good cooling of the sleeves and

90981 1/0258

a possibility of using different types of liner spring suspensions, taking advantage of the positive ones Properties of the independent wheels is retained.

The task is carried out by a bogie for different gauges solved with independent running wheels instead of wheel sets. Each impeller is on a short axis through which it is in a bushing is stored, shrunk on. The wheels on one side and the other of the bogie for different Gauges are through a frame in the appropriate, independent, on one of the rails of the railway track moving side frames connected to each other. There is a rectangular cross opening in the center of each side frame appropriate.

The connection with the vehicle is made by a transverse Spring top beam with a central bearing, on both sides of which side sliding blocks are attached as external supports for the car body are.

The upper spring beam is on the in the rectangular openings of the Side frame lying spring sets supported. The spacer spring lower bar is located parallel to and below the spring lower beam, on which the leaflet sets are supported. The spacer spring lower beam is longer than the spring upper beam and its beam ends are on both sides in the circumference of the narrowest Gauge in front. Toothed plates are located on the underside of the spacer spring lower beam in the zone of the rectangular openings attached, which are interlocked with the teeth attached to the side frames. The grooves of the tooth plates mesh with the Teeth of the side frames and are parallel to them and to the sliding axis. The number of grooves in the tooth plates and their tooth pitch are selected in such a way that their meshing corresponds to the various track widths for which the bogie is intended. The teeth are attached with respect to the wheel rim rolling circle so that they are always equally loaded and the connection between the independent side frame and the spacer

909811/0258

the lower spring beam is secured.

The tooth height h ^ of teeth with tooth plates is smaller than the play h ₂ between the upper part of the rectangular openings and the upper spring beam. This ratio depends on the elasticity of the spring set, which is always selected so that its static sag is less than or equal to hp. The play h ₂ between the upper part of the rectangular openings and the upper spring beam is greater than the toothing height h> | of the teeth on the tooth plates, but smaller than the extent of the static compression of the spring sets under their own weight.

To compensate the running wheels are under the spacer spring lower beam Documents provided at the points in contact with the gauge change facility.

The gauging system from one to the other track gauge contains two lateral roller tables, treadmills or slide rails that make contact with the laterally protruding ends of the spacer spring lower beam. The rail track in the gauge change system consists of three sections: Sin upwardly inclined section with the narrower gauge S ₁ , a horizontal section - _{widening from the narrower gauge S 1} to the wider gauge S ₂ , and a downwardly inclined section with the wider gauge S ₂ .

According to the invention, the bogie for different track widths allows vehicles equipped with it to move to carry out quick, safe, convenient re-gauging between all normal and wide gauges without having to do so manual labor or interlocking mechanisms are used. The bogie dimensions are not based on the vehicle mass limited, their construction is simplified and light. There is the possibility of wheel coupling of brake controllers, Odometers, speedometers, generator gears, including the possibility of a motor drive. In contrast to dexi

909811/0258

conventional wheel sets, the devices mentioned can also be coupled to the inner sleeves of the free running wheels will.

In addition, the steering forces generated when cornering are insignificant, which significantly reduces the wear and tear of running wheels, their flanges and rails. Also the influence from outside Factors that cause lateral fluctuations are greatly reduced. The axles are much easier to ground. There is no torque arises in the press connection between axle and wheel circle, the high demands on this connection are no longer applicable. The resistance is significantly reduced in the track curves. There at If the brakes do not slide between the track and the running wheel, the tendency to drag is also reduced. Since the wheels are a have independent movement, attaching wheels of different diameters is quite possible.

The invention is explained in more detail, for example, with the aid of the drawing. It shows:

The bogie 1 for different gauges of the vehicle 2 consists of two independent side frames 3 and 3 ¹ with each frame 15 assigned to the two rails 4 and 5 and with independent running wheels 6, each on both sides of the bushings 7 and 8 are stored and equipped with sleeve springs and brakes.

The vehicle 2 is connected to the independent side frame 3 and by means of the upper spring beam 9, on which a central bearing 10 and lateral sliding blocks 11 located ^{outside the side frames 3 and 3 1 are attached.} About the spring kits

12, the upper spring beam 9 lies on the lower spacer spring beam

13, the ends of the bars protrude on both sides. The feather top beam 9 and the spacer spring lower beam 13 go through the rectangular openings 14 of the frame 15 of the independent Side frames 3 and 3 'that serve as guides for them. Laterally in the lower part of each rectangular opening 14 are each two teeth 16 and 17 attached, which are toothed with the corresponding grooves 18 of the toothed plates 19, which firmly on the underside of the spacer spring lower beam 13 are attached. The teeth 16 and 17 and the grooves 18 are parallel to the Rails 4 and 5.

In order to achieve locking in the event of an accident in this position of the bogie elements, the toothing height hj of the teeth 16 and i7 in the grooves 18 must be smaller than the play h ₂ between the upper spring beam 9 and the upper part of the rectangular opening 14 under its own weight. The static sag of the spring sets 12 must be greater than or equal to h ₂ .

When changing gauges, the bogies drive through the gauging system for different gauges 1 without being separated from vehicle 2 with three working sections, which the roller tables 20, the laterally protruding beam ends from below of the spacer spring lower beam 13, contains. The inclined

90981 1/0258

te section I has a narrower track width S ₁ , the horizontal section II a _{track width widening from S 1} and Sg and the downward sloping section III a wider track width Sp. Up to section II, the vehicle 2 and the associated, Parts lying above the spacer spring lower beam 13 opposite the independent side frames 3 and 3 'of the bogies 1 are raised to the height h, which is greater than the toothing height h ^ of the teeth 16 and 17 in the grooves 18. When the vehicle 2 drives through section II a gradual lateral displacement of the independent side frames 3 and 3 'is effected by the lateral constraining rails from the track width S ₁ to the track width S ₂ , in which the teeth 16 and 17 come to stand opposite other grooves 18. In section III, the grooves are lowered onto teeth 16 and 17. The running wheels 6 have the new track width Sp.

It is possible in the case shown in Figure 1 to determine / nits ^r ier different Spurv. Since the gauging system is symmetrical, vehicles can drive through it in both directions.

In order to compensate for the wear of the running wheels 6, there is the possibility that in the contact zone of the spacer spring lower beam 13 with the roller table 20 on the underside of the beam, supports are attached which, in the case of a highly elastic bushing spring suspension can be used for setting.

The bogie can thus be used for various narrow and wide gauges. This enables combined transports over narrow-gauge railway tracks, their gauge widths in some Countries are very diverse.
