Wheel axle steering for railway bogies.

The invention relates to a Radsatzsteuerung for bogies according to the preamble of claim 1.

Radsatzsteuerungen this type are known from DE-OS 3,827,412.

Purpose of the invention is a positive control of the wheel sets to this screw in the opposite direction when the vehicle is traveling on a curve, and the bogie relative to the wagon or locomotive body ausdreht.

The known positive control was aimed to bring the wheel axles in curves in a radial position to bring wear of wheel and rail to a minimum. The construction according to DE-OS 3,827,412 traction and braking forces are transmitted through the control lever on the car body. This results in the sensitive control constantly forces.

The object of the invention is the provision of measures by which eliminates the last-mentioned drawback of the known construction and optimization of the positive control and thus a more precise adjustment of the wheel axles is achieved in the Radial.

This object is achieved according to the invention in a bogie of the kind mentioned by the measure according to the characterizing portion of claim 1.

Further advantages of the invention are achieved by the measures in the dependent claims.

In the drawings, an embodiment of the Radsatzsteuerung is illustrated. Show it<ul><li>1 is a plan view of a bogie with a positive control,</li><li>Fig.2 shows detail A of Figure 1 in side view.</li></ul>

When Radsatzsteuerung according to Figures 1 and 2 is connected to a locomotive body 34 and with a bogie frame 32 referred to in which two sets of wheels 11, 11 'with their Arhsen 15, 15' and the wheels 16, 17 and 16 ', 17' are supported. To drive the wheels serve Store 12, 12 'with their gear 13, 13', wherein the motor bearings in accordance with the procedure described in the Austrian Patent Application A 415/90, may be executed.

Each of the two sets of wheels 11 or 11 'or its axle bearing is on the outside of the wheels 16, 17 and 16', 17 connected 'to a respective Radsatzführungshebel 5 or 5A and 5' and 5A '. The two Radsatzführungshebel 5, 5A and 5 ', 5A' of each pair in the direction of travel one behind the other arranged wheels 16, 16 'or 17, 17' are articulated on a double-armed lever 2 and 2A, which is a vertical pin or around 3 3A is pivotally mounted in the central crossbeam 14 of the bogie frame 32nd Hiebei are the Radsatzfürhungshebel 5, 5A of a wheel set 11, in each case at the inner joint 4 and 4A of the one arm of the double-armed lever 2 and 2A connected, while the outer joint 8 or 8A of the second arm, on which the respective Radsatzführungshebel 5 'and 5A' of the second wheel set 11 'is hinged, is connected to a longitudinal arm 1 and 1A, which is connected with its other to a downward projecting lever 7 a torsion shaft 6, which is located in the locomotive body 34 and transversely extends to the driving direction. Since initiation of traction and braking forces to a displacement between the bogie and the locomotive body gives that Zwangssteurung must be decoupled along. There are introduced into the trailing arm only restoring forces due to Drehgestellausdrehung. The longitudinal decoupling is done by the torsion bar.

With the lever ratios a: b at the two-armed lever 2 and 2A can be the wheel sets, depending on the displacement angle of the bogie and the rigidities that are realized in this coupling mechanism and the wheel set, rotate to the desired position. Thus, the wheel sets are largely provided radially in the bow and thus brought about a significant reduction of wear and wheel / rail forces.

The traction and braking forces are transmitted separately via an unillustrated Tiefzugeinrichtung the bogie on the locomotive body. this is accomplished via the wheel set and the Radsatzführungshebel 5, 5A, 5 '5A' intermediate wheel set and bogie. The bogie frame 32 is rotated about a vertical axis 9 with respect to the carbody 34th The construction according to the invention acts in the following manner:

If the bogie enters a bow and twists in the direction of the arrow A about the axis 9 with respect to the locomotive body, the control lever twisting 2 or 2A in the direction of arrows B and B 'to the pin 3 or 3A and bring about the Radsatzführungshebel 5, 5a, 5 ', 5A', a turning of the wheel sets 11 and 11 '.

Hiebei pivot the wheel sets in the opposite direction, so that the paths of the wheel sets in the directions X and X 'and Y and Y' are the same. By translating the length a / b of the arms of the control lever 2 and 2A, the recess or radial control of the wheel sets is determined. Hiebei can be adjusted the length of the lever arms.

The longitudinal arm 1 and 1A and the Radsatzführungshebel 5, 5a, 5 ', 5A' must have a certain rigidity, which is indicated by the drawn spring symbol. These rods transmit tensile forces on the one hand and on the other hand braking forces and have the task to trap longitudinal vibrations.
