Definitions
- the invention relates to a drive for rail vehicles with a damping version for the axle guide, the bogie or vehicle frame itself via spring elements on the with longitudinal and transverse play supported axle bearing housings of the wheelset.
- the object of the invention is a drive for rail vehicles of the type mentioned at the beginning, the special design and arrangement of the Damping version for the axis guidance the damping improved, high driving speeds possible, ensures a safe curve of the vehicle while reducing the disadvantages of the aforementioned known designs.
- the proposed Execution is intended to influence the damping behavior the drive are exercised with clearly defined damping sizes and with a minimized Number of components influencing damping.
- the object is achieved by the features of the claim solved, i.e. that vertical and Horizontal shock absorbers by their arrangement to each other and by their arrangement at attachment points of the The bogie or vehicle frame correspond to each other in such a way that when the horizontal shock absorber moves a rotational movement of the axle bearing housing is generated, which in turn by the vertical shock absorber is additionally damped, the longitudinal movements of the wheelset from the horizontal shock absorber and the Vertical shock absorbers can be damped and simultaneously in a diminished form this also applies to the transverse movements of the wheelset applies.
- the vertical shock absorber is in the damping characteristics of the horizontal shock absorber involved. By changing the attachment points of the horizontal shock absorber and thus by the The change in the line of force action becomes this cut below the horizontal axis and forms to the mounting brackets and defined adjustable angle so that the damping component of the Vertical shock absorber is variable.
- the vertical shock absorber 3 is between Axle center 1 and axle coil spring center 2 approximately vertical and the horizontal shock absorber 8 is in an angle to the longitudinal direction of the vehicle and in one inclined to the horizontal between frame 7 of the bogie or vehicle and the axle housing 6 arranged.
- the horizontal shock absorber 8 is attached to the frame 7 at attachment point 4 and with his other End at articulation point 15 on one on the axle bearing housing 6 arranged mounting bracket 5.
- the mounting bracket 5 is arranged so that the pivot point 15 of the horizontal shock absorber 8 at a distance a to the vertical axis center 1 and a distance h to the horizontal axis center 13 is mounted.
- the Line of action 12 of the horizontal shock absorber 8 cuts the vertical axis center 1 in one Point that is at a distance c from the horizontal axis center 13 lies in the top view according to Fig Force line 12, the wheelset center line 10 and forms the distance b to the connecting line 11 between front and rear coil springs 14.
- This distance b can depend on the chosen one Articulation point 15 be greater or less than zero.
- the cheapest damping and thus maximum driving behavior is determined by the articulation point 15 reached, influencing the vertical shock absorber 3 through the horizontal shock absorber 8 and thus the additional damping effects also empirically can be determined, i.e.

Description
Nach US-A-4 561 360 ist eine symmetrische und minimale Dämpferanordnung für alle drei Dämpfungsebenen (vertikal, horizontal quer und horizontal längs) bekannt. Diese Vertikaldämpfung erfordert eine möglichst senkrechte Anordnung der Dämpfer. Hohe Fahrgeschwindigkeiten erfordern eine definierte Horizontaldämpfung. Der in dieser bekannten Anordnung vorgeschlagene Kompromiß ist nur für niedrige Fahrgeschwindigkeiten geeignet.
