"Bogie for locomotives"

The invention relates to a bogie for locomotives with axles arranged at a distance and equipped with rail wheels tginem bogie frames supported on the axles and öinem transverse 'supported along its length on the bogie frame spar, which is about a perpendicular through the middle of the bogie frame extending axis is pivotable and carries upright springs at its ends, on which a subframe the locomotive body is at rest.

Bogies of the type mentioned are equipped with drive motors that act on the axles. Through the Effect of this drive motor creates tensile forces that dero Bogie must be transferred to the vehicle or locomotive body. In the case of known bogies, the one in question standing type serve for this power transmission essentially

lichen horizontally and in the direction of travel or the longitudinal direction of the bogie running individual links on each side of the vehicle extending from the vehicle body to the cross member. As a result of the restrictions that are given by the necessary ground clearance, such handlebars χΠ considerable distance above the rail or track body to be ordered. This has the consequence that when tensile forces are transmitted from the bogie to the track body fall respiratory forces are generated, which strive to the anterior jncle of the bogie to move up while the winter end is pushed down. This apparent Movements take place as movements around a transverse £ ... '.' & E, which runs through the connection points of the handlebars with the crossbar. The result is a reduction in stress the front axle and an increase in the load on the rear axle. The life of the bogie is thereby impaired.

The invention is based on the task of these nights:.! -. avoid au.

To solve this problem, this is indicated in the introduction Rolled bogie according to the invention characterized in that longitudinal centering and compensating devices at the ends of the cross member are arranged, on which a pair of links attack on both sides of the bogie, which in longitudinal

direction are spaced apart and in the longitudinal direction of the bogie are opposite to each other and run upwards and at their ends with the locomotive subframe are connected, so that this is independent of normal height and not influenced by the handlebars lateral deflections of the upright springs, against Movements in the longitudinal direction of the bogie are recorded. It is advantageous if the axial extensions, the two links provided on each side of the vehicle cut approximately at the level of the track body. The task of the equal and longitudinal centering devices consists mainly of α:.;: ...., to prevent the springs, through which the locomotive or vehicle body is supported on the cross member, through the both handlebars provided on the vehicle are prevented from making movements.

FIG. 3 shows a sectional view of the bogie with the sectional plane running along the line 3-3 in FIG.

Rail wheels 1 are in the Pig. Bogie shown on mutually spaced parallel to each other Axes 2 and 3 attached. The ends of the axles 2 and 3 are rotatable outside the rail wheels 1 recorded in storage boxes 5.

Ss a rigid bogie frame is provided, which advantageously is integrally formed as a cast steel part. It has side frames 7 which are arranged at a lateral distance are and run in the longitudinal direction of the bogie. These side frames 7 are outside the rail shutters 1 arranged. Si.e are rigidly connected to each other via a cross member 9, which is centered between the axes 2 and 3 runs. An additional connection is made via cross members 11, which are seen in the longitudinal direction of the chassis each run outside of axes 2 and 3. The side frames 7 have recesses oriented in the height direction equipped, which are provided in the vicinity of the storage boxes 5, and form console-like yoke surfaces 13, between which the storage boxes 5 are slidably received in the vertical direction. In this way, the axles are held in their position laterally or transversely to the bogie frame. On the tops

909843/1091

the storage box 5 are supported by helical spring arrangements 15, which are used for resilient mounting of the side frames 7. With these peder arrangements the bogie frame is in front Protected against bumps that are initiated via the rail wheels from the track structure. At the same time they work. But spring arrangements also counteract tilting movements of the bogie frame about a transverse axis.

Drive motors M, which are on the axes 2 and ^ 3 are stored and are supported with their claws on suitable abutments on the central cross member 9. To the geared The common gear boxes G are used to connect the drive motors M to the two axles 2 and 3.

TJm pivoting movements of the bogie in relation to the vehicle or locomotive body subframe 13 carried by it to enable, the middle cross member 9 is at its center with a vertically extending cylindrical recess 17 provided, while the side frames 7 upwardly facing flat, substantially horizontally extending bearing surfaces 19, which are arranged in the longitudinal direction of the bogie at a distance and with respect to the transverse center line of the bogie are arranged symmetrically.

A cross member 21 is equipped with a downwardly facing cylinder pin 23, which is articulated in the cylindrical

Recess 17 is added. The cross member 21 also has downwardly facing bearing surfaces 25 which are larger Have surface than the bearing surfaces 19 on the side frame 7, but ± ip. Transverse spacing and in terms of the longitudinal spacing are just as far apart as the bearing surfaces 19 of the side frames. Because of these superimposed Bearing surfaces 19 and 25 can pivot the bogie with respect to the vehicle body Uriter frame U about the cylinder journal 23 or the cylindrical recess 19, which acts as a pivot joint. The transverse and longitudinal spacing mutually arranged, superposed bearing surfaces 19 and 25 prevent the cross member and the bogie frame perform tilting movements about transverse or longitudinal axes with respect to one another.

At its ends lying laterally outside the side frames 7, the transverse spar 21 is provided with pockets 27 that are open at the top equipped, which are used to accommodate springs o To transverse movements of the vehicle body subframe U with respect to the To enable the bogie, 27 vibrating metals are arranged in each pocket, consisting of horizontally arranged rubber cushions 29 and metal plates 31 arranged therebetween and carry upwardly pointing spring seat plates 33. the Spring seat plates 33 in turn carry a pair of upright metallic helical springs 35 on which the vehicle body or Locomotive body subframe U via cap-shaped spring

plate 37 is supported directly.

The structure described makes it possible that the subframe U executes vertical movements with respect to the cross member 21, wherein the springs 35 are deflected in the vertical direction. But there are also lateral movements of the subframe U with respect to the transverse spar 21 possible, with a shear stress and deformation of the springs 35 and the rubber cushions 29 occurring.

In order to limit the lateral movement, the sub-frame U is provided with downwardly depending stops equipped, which are arranged within the cap-shaped spring plate 37, true! the cross member 21 upright has abutment-like stops 40 which are arranged at a distance within the stops 38 of the subframe and wear elastomeric pads or shock absorbers 42.

In order to dampen the movements occurring in vertical and lateral directions, upright stands are to be found at the ends of the crossbar Shock absorbers 39 and provided along the length between its ends horizontally arranged shock absorbers 41, which at their free ends are connected to the vehicle subframe U.

To reduce the weight transfer from one axle to the other, the ends of the cross member 21 are in Arranged in the longitudinal direction of the bogie and extending from the center outward and ascending handlebar 43 with the Vehicle subframe U- connected. The longitudinal axes of this Control arms 43 converge with respect to one another and the points of intersection of the longitudinal axes lie in the plane of the track body, so that the resulting, from the two of the handlebars

low altitude, d. H. the level of the track body, acts.

To connect the link 43 to the subframe U are used Abutments 45 attached to the subframe, as well as Cushions 47 made of resilient material, which are used to allow angular movements of the handlebars with respect to the abutments. Such angular movements are required when the subframe is laterally and vertically in relation moved on the cross bar of the bogie.

In order to prevent the work of the support springs 35 from being hindered by the link 43, are at the ends of the cross member Flanges 44 and 46 are provided which are laterally spaced from one another and pockets open at the bottom limit, while longitudinal centering and compensating devices to connect the handlebars to the ends of the crossbar serve, each consisting of a pair of angle levers with nearly

vertically extending arms 49 and 50 and substantially horizontally extending arms 51 and 52 are made to transverse axes are rotatably supported within the pockets. The axes of the angle levers are made by hinge pins 53 and 54 formed. The substantially horizontally arranged arms 51 and 52 of the two angle levers are directed towards each other, with the inner end of arm 52 ^ overlying the corresponding end of arm 51. Both ends of the horizontally extending ' are connected to one another via a relatively short coupling link 55 extending in the vertical direction, namely in the Way that the ends of the coupling link are articulated via bolts 56 and with the ends of the arms 51 and 52.

The inner ends of the links 43 (i.e., those towards the center of the bogie pointing ends of these links) are equipped with forks, which the lower ends of the arms 49 and 50 of the Include angle levers and are connected to these via bolts 61 or ball joints 63. The ball joints are used on all sides To enable relative movements of the links 43 with respect to the arms 49 and 50. Such relative movements must be possible because of vertical and lateral movements of the vehicle subframe 17 can occur with respect to the cross member of the bogie. The device described represents a Movement reversing and doubling device is. If the springs 35 are compressed, then the shortened

Height distance between the subframe and the cross member. The associated movement of the inner ends of the links 43 towards each other is balanced by the angle levers 49 »50 and 50, 52, which are clockwise and counterclockwise be pivoted. The pivoting paths are the same because the angle levers via the coupling link 55 are connected. With this pivoting, however, there is no undesired pendulum or pivoting movement of the transverse spar generated with respect to the subframe. When forces arise which act in such a way that they laterally the subframe Seek to move with respect to the cross member, then the result is angular positions of the handlebars in a horizontal plane, and there are corresponding movements of their inner ends in the direction away from each other, which in turn by the angle levers 49 »51 or 50, 52, which pivot clockwise and counterclockwise be balanced.

The transfer of forces acting in the longitudinal direction of the bogie from the cross member 21 to the subframe U does not lead to any Movement of the bell crank. For example, if the bogie when looking at Figs. 1 and 2 in the direction to is driven on the right, then a compressive force is created in the front link 43, which tends to control the associated angle lever 50, 52 to pivot clockwise, while the tensile force generated in the rear link 43 is a clockwise

909843/1091

meaningful pivoting of the angle lever 49, 51 to generate searches. The coupling link 55, however, has the effect that these torques of the angle levers are of equal magnitude to each other counteract. As a result, the angle levers remain in their positions as long as there are none in the lateral or vertical direction Deflections of the springs 35 or elastomeric pads 29 take place in the manner already described.

In all such states that occur, there remains one that runs in the perpendicular direction across the center of the transverse spar Plane in its centered position, d. H. it remains the same, unchanged in the longitudinal direction of the subframe Distance between the ends of the links 43, so that the position of the cross member with respect to the subframe in the longitudinal direction remains fixed. This longitudinal centering results because the links 43 are firmly connected to the subframe Abutments 45 are immobile with respect to this. In the Longitudinal direction of the bogie ναι one end of a link 43 to the next running route is therefore independent of the height and / or lateral position of the subframe in with respect to the transverse spar of the bogie, always through the transverse to the bogie through the center of the transverse spar 21 running plumb line cut in half.
