The baseplate? this spring Fig. 6 shows a similar arrangement as is on the side of the bogie frame in A b b. 1 a b b. 4, in which a rubber ball joint 14 is screwed on instead of the layered position visible or held between rubber spring 10 and is provided in the same way. Instead of a rubber ball joint, it can bend like the steel liners. While a rubber swivel joint is also used,
flat base plate and flat steel intermediate layers Fig. 7 shows an embodiment, in which the rubber spring 5 is mainly due to flexure instead of the in the embodiment according to A b b. 4 is claimed, in the case of compression-thrust rubber springs seen in the form of a circular arc, the thrust stresses predominate for the formation of the parts. In 55 the vertical compressive forces would take a so-called A b b. 2, the position on bell spring is provided in dash-dotted line, in which Walk rings 15 are interpreted, which the spring arrangement assumes when driving through between pin 16 and bell-shaped parts 17 of a curved track. Such an inclination lie. As a flexure spring, a change in the spring characteristic against the vertical thrust rubber spring 10, as in the embodiments, results in right-hand compressive stress, which, however, in 60 according to A b b. 4 and 5, or a rubber ball can be purchased. The joint or rubber swivel joint shown, as in Fig. 6, shift occurs when driving through the smallest permissible.

When traveling through the smallest of the embodiments described above Curve radii of shapes permitted in operation cannot be avoided that the about 250 m, the deflection is only about the 65 vertical load-absorbing springs, if Half, and the maximum roll-off distance is roughly the amount of the spring arrangement by rotating the 70 mm. The resulting inclination of the bogie tends to be loaded differently. The spring arrangement has practically no disadvantageous effect.

area 2 are affected. This can be prevented by the fact that, as in A b b. 8 and 9 shown, the The order of the springs is reversed so that they absorb the vertical loads Spring elements do not participate in the pivoting movement that the rolling surface 2 executes. At this Arrangement are the pressure-thrust rubber springs 20 absorbing the vertical pressure forces firmly connected to the bogie frame, adjustable in height. These springs carry an intermediate piece 21, on which, via a flexible rubber element 22 and supports 23, the plate with a spherically shaped rolling surface 2 is arranged. In this arrangement, when the bogie is rotated against the Car body the bending stress from the flexible spring element 22 so largely absorbed, that the springs 20 are loaded only slightly differently. Again you can Additional springs 24 may be provided around the part of the spring arrangement that absorbs the vertical loads to give a progressive characteristic.

In this arrangement, the flexible spring element 22 can again, as in the arrangement according to A b b. 6, can be replaced with a rubber ball joint or a rubber swivel joint. To vote the transverse suspension can also be provided here, as in the embodiment according to Fig. 5, additional springs that generate additional restoring forces in the transverse direction.

In the exemplary embodiments, it is assumed that the spring arrangement is rigid with the bogie is connected and the curved or convex surface 2 rolls on the car body. Of course All arrangements can also be arranged so that they are rigidly attached to the car body and the surface unrolls on the bogie.
