Abstract
ABSTRACT OF THE DISCLOSURE
Because of wear on the running surfaces of wheel rims of rail vehicles it is necessary to provide a method for adjusting the height of the axle box. For this purpose the invention provides for the insertion of spacer pieces between the wedge grip suspen-sions of the primary suspension. In order to lock them into posi-tion and to make assembly easier, these spacer pieces are secured against displacement by means of cylindrical pins. For greater usefulness the spacer pieces are provided with bearing surfaces of various levels so that in order to readjust the height it is only necessary to rotate the spacer piece until the surface with the desired height is brought into load-bearing contact with the wedge grip suspension.

Description
The invention concerns a ver-tically-adjustable axle box for rail vehicles in which the primary suspension of the axle box housing vis-a-vis the bogie frame is provided by means of metal/
rubber springs.
Fo~ the primary suspension of rail vehicles a generally known ~Qethofl is the provision of wedge-shaped spring means made of rubber and metal wafers in which the layers are alternated and bonded to one another by means of vulcanization. In this method an axle box housing is directly connected to a suspension element while the other end of the suspension element is similarly directly con-nected to a bogie frame.
In accordance with -Rubber in Rail Vehicle Suspension from -Modern Railways , Issue No. 9, 1967, a further known method for adjusting wheel sets using metal/rubber springs is to not connect the suspension elements directly to the bogie frame but, instead, to connect them -to a separate frame, this frame then being itself con-nected to the bogie frame by means of bolts. In this method, the bolts are seated in vertically-running, slotted holes in the frame which allows for a vertical adjusting of the wheel set relative to the bogie frame. Such a device does indeed permit the vertical movement of the axle box vis-a-vis the bogie frame in order to change the axle load distribution or to compensate for the wear on the wheel rims, however, the design is relatively expensive to manufacture and, because of the width requirement i~posed by the additional frame, one that can be used only on plate metal frame bogies and not on those that have box-type sectional girders.
As opposed to this, the application is based on the objective of creating a device for facilitating the vertical adjustment of axle boxes which will require only minor additional construction costs and, in addition, will be usable for bogies with box-type sectional girders.
This objective is achieved, in accordance with the inven-tion, in that spacer pieces acting in the vertical direction are provided between the axle box housing and the wedge grip suspensions -1- ~
- 1~5629~
which are non-slidably connected to the metal/rubber springs, and in that the axle box housing is mounted in the wedge strip sus-pensions so that it is movable vertically, yet is rigidly fixed in position horizontally.
By Means of -the vertically movable connection of the axle box and metal/rubber spring via the wedge grip suspension it is possible to insert simple spacer pieces which permit adjustment in elevation without an increase in width, so that the type of constrction as per the invention is usable with both plate and box-type sectional grider frames. In addition, the supplementary construction costs are minimal and the adjustment of height can also be carried out by less qualified personnel.
Embodiment examples of the invention are illustrated in the drawings, wherein:
Figure 1 illustrates a vertically-adjustable axle box wi-th spacer pieces located at the top;
Figure 2 illustrates a vertically-adjustable axle box with spacer pieces located at the bottom;
Figures 3, 4 and 5 illus-trate alternative guidance structures for the axle box relative to the wedge grip suspension;
Figure 6 illustrates a means for locking a spacer piece into position in the axle box housing and in a projection on the wedge grip suspension by the use of a cylindrical pin;
Figure 7 illustrates a cube-shaped spacer piece with bearing surfaces at various levels; and Figure 8 illustrates a cube-shaped spacer piece in the installed state locked into place by means of cylindrical pin.
An axle box suspension using metal/rubber springs is illustrated in Figure 1. The axle box 1 is guided within wedge grip suspensions 2 so that it is slidable in the vertical direction but non-slidable in the horizontal direction, said wedge grip sus-pensions being located between the axle box 1 and the metal/rubber springs 3 and being guided in the metal/rubber springs 3 by means of their wedge-shaped design, whereby the metal/rubber springs 3 is designed, as is customary, in the form of a compact packet having successive layers of rubber and metal elements which are bonded together by means of vulcanization. The metal/rubber springs 3 are supported in the known manner directly against a bogie frame 4 which is designed as a box-type sectional grider frame.
For the adjustment of the axle box 1 in the vertical direction relative to the bogie frame 4 there are provided spacer pieces 7 between the axle box housing 5 and a projection 6 which juts outward at the top of the wedge grip suspensions 2. The spacer pieces are guided transversely to the direction of the axle by means of a recess 8 on the axle box housing 5. In the axial direction, cylindrical pins 9 are provided to lock the pieces into position (Figures 6, 8). The left half of Figure l shows the axle box 1 in the original state, while the right half shows the axle suspension with worn-down or stripped-off running surfaces lO. I,n order to keep the bogie frame 4 at its original level a supple-mentary spacer piece 11 has been inserted.
Figure 2 illustrates a variant of Figure l having spacer pieces 7, ll located at the bottom. The spacer pieces 7, 11 are mounted on projections 12 which just out beyond the axle box housing 5. The guidance of the spacer pieces transversely to the direction of the axle is taken over by the axle box housing 5 itself and by a recess 13 in the wedge grip suspensions 2. In the axial direction, the locking of the pieces into position is done by means of cylindrical pins as already explained under Figure l. The right half of the drawing once more shows the insertion of a second spacer 11 in order to keep the bogie frame 4 at a constant level in spite of a worn-down or stripped-off running surface 10.
Figure 3 reproduces a guidance method of the wedge grip suspension 2 vis-a-vis the axle box housing 5. For this purpose the axle box housing 5 is provided with a vertically-running projection 13 which is guided in a groove 14 of the wedge grip suspension 2, which permits vertical movement of the axle box housing but prevents horizontal displacement.
Figure 4 illustrates a reversal of the principle given in Figure 3, in which the projection 13 belongs to the wedge grip suspension 2 and the groove lL~ is assigned to the axle box housing 5.
Figure 5 shows a spring 15 which gives guidance in the vertical direction to the axle box housing 5 or wedge grip suspen-, ~ ~ on 2, provided with grooves~
The method of securing -the spacer piece 7 is shown in Figure 6. The spacer piece 7 is secured against displacement by means of a cylindrical pin 9. The cylindrical pin 9 is driven into the axle box housing 5 and penetrates through the jutting-out pro-jection 6 of the wedge grip suspension 2.
A special embodiment form of the spacer piece 7 is shown in Figure 7, this piece having various levels as established by the bearing surfaceæ 16a to 16d (delimited by the surface diagonals) of a cube 17. These surfaces 16a to 16d are penetrated perpendicu-larly by a drill-hole 18 which accommadates the cylindrical pin 9 so that, when the cube 17 is rotated around the drill-hole 18, it is possible to set four different levels of elevation.
The cube 17 is installed along with a spacer piece 7 between the axle box housing 5 and the projection 6 on the wedge grip suspension 2 (Figure 8).' B~ rotating the cube 17 around the c~lindrical securing pin 9 it is possible for the cube alone to establish four elevation adjustment positions. In addition,, more spacer pieces can be inserted should this be necessary.
