Rotary pan for bogies of rail vehicles

The Ileuerung concerns a rotating pan for bogies of Track vehicles, consisting of a lower, = concave, steel mounting cable attached to the bogie and a steel upper spherical part attached to the body of the car and resting in it.

There are rotary pans for bogies of rail vehicles known, in which in a concave steel receiving part, which is attached to the bogie, an upper, attached to the car body, rests steel ball part, and through a lubrication of this bearing is achieved that rotations about the vertical axis and cardanic movements under only less Friction take place. With this rotating pan construction, the lubricant is already in place after a short running time, despite the fact that it is attached Oil grooves pushed aside. As a result, occurs faster wear of metal parts. The friction is increased and hinders the movement, so that this is a high Requires effort and jerks with loud noise he follows.

The innovation is based on the task of providing a completely maintenance-free and wear-free rotating socket for track vehicles

a lower, concave, steel attachment part attached to the bogie and a steel attachment part resting in it

When twisting this

'■' Rotary pan around the vertical axis and with cardanic movement, which is often caused by rail unevenness and when cornering, only a pure molecular shift occurs in the rubber, but no sliding movement of the upper and lower parts on each other. Since any sliding movement is avoided, the upper and lower part of the rotary pan assembly move around the vertical axis and gimbal without friction and noise, and the element works completely maintenance-free and wear-free. Furthermore, since there is no initial friction, there is no breakaway torque

The firmly adhering connection of the spherical rubber layer with the metal parts on the * top and bottom prevents the rubber layer from stretching transversely on the liaftf surfaces and thus enables high pressure loads to be absorbed with high fatigue strength and constant fire characteristics. An unattached rubber layer is not able to constantly increase in diameter under the pressure stresses running outward in the individual layers in parallel to the pressure-loaded surfaces

and decreasing in thickness.

Since the heavy metal parts of the rotary ladle unit were only brought into the vulcanizing press with complex lifting equipment and the heating of these parts has long since been claimed, v / enn a perfect vulcanization and good Adhesion is to be achieved, according to the innovation at the bottom the rubber layer only a light sheet pressed from sheet metal, Ie firmly adhesive vulcanized and the actual vulcanized part is much relieved. After completion, the vulcanized sheet metal shell with rubber and upper part is attached to the Assembly of the vehicle is inserted into the receiving shell of the bogie and there with some welding points, screws or otherwise attached.

In a further embodiment of the innovation, the radius of the spherical upper part is smaller than that of the receiving shell. So that the rubber layer to the vertical axis of the EIe- 'mentes becomes thinner is achieved, and it is therefore to be incorporated readily in a position to be encountered in high compressive stresses, as ■ a thin layer consists of transverse strain occurring under pressure against higher resistance. At the outer edge, which is already strongly inclined to the vertical direction, there is only a small pressure component under the weight of the vehicle body and the prevention of transverse expansion of the rubber layer is of no importance here. Therefore the Gurrjni layer can be kept thicker here. It offers the advantage of a smaller restoring torque when the bogie is deflected.

After all, after the fire it is intended that the spherical top used as the lid of the vulcanizing mold will. To simplify the production of the very heavy., Crk piece and to avoid the use of hoists, not only must the vulcanizing part and its metal parts be low Have weight, but also the required vulcanization shape. The vulcanization mold is created by designing and using the upper part of the drain pan element as a molded cover / "" ") much lighter and therefore more convenient to use, and dia Production of even large rotary socket bearings can be carried out quickly and economically.
