Problems solved by technology

In this context, due to the relatively long torsion bars in the known rolling bearings, during operation of the rail vehicle, the torsion bars may cause significant vibrations due to specific bending modes at specific excitations
In addition, due to the increased number of components to be placed in the area of ​​modern running gear, especially the more stringent space requirements inside the running gear, this leads to increased problems when placing components, in particular how to accommodate the torsion arms of rolling bearings. Movement provides enough free space

Embodiment Construction

[0030] Now refer to figure 1 and figure 2 , the rail vehicle 101 according to the preferred embodiment of the invention can be described in more detail, which comprises a rail vehicle unit in the form of a running mechanism 102 according to the preferred embodiment of the invention. In order to simplify the following description, the xyz coordinate system is introduced in the drawings, wherein (on a straight horizontal track), the x-axis represents the longitudinal direction of the running mechanism 102, the y-axis represents the transverse direction of the running mechanism 102, and the z-axis represents the running mechanism 102 height direction.

[0031] Vehicle 101 is a high-speed rail vehicle with a nominal operating speed above 250 km / h, more precisely between 300 km / h and 380 km / h. The vehicle 101 includes a carriage body (not shown), which is supported on the running mechanism 102 through a suspension system. The running gear 102 comprises two wheel units, which ta...

Abstract

The present invention relates to a rail vehicle unit comprising a first vehicle component (104), a second vehicle component (111) and a rolling support device (112), the rolling support device (112) counteracting rolling motion between said first vehicle component (104) and said second vehicle component (111) about a rolling axis. The rolling support device (112) comprises a torsion bar (112.1), a first torsion arm (112.2) and a second torsion arm (112.3). The first torsion arm (112.2) is rotationally rigidly connected to a first end section of the torsion bar (112.1) and is articulated to the first vehicle component (104), while the second torsion arm (112.3) is rotationally rigidly connected to a second end section of the torsion bar (112.1) and is also articulated to the first vehicle component (104). The torsion bar (112.1) is pivotably mounted to the second vehicle component (111) via a first support element (113.1) and a second support element (113.2), the first support element (113.1) and the second support element (113.2) being mutually spaced by a support distance along a longitudinal torsion bar axis (112.6) of the torsion bar (112.1). Furthermore, at least one intermediate element (114.1, 114.2) is provided, the intermediate element (114.1, 114.2) being connected to the second vehicle component (111) and cooperating with the torsion bar (112.1). The intermediate element (114.1, 114.2) is located between the first support element (113.1) and the second support element (113.2).

Description

technical field [0001] The present invention relates to a rail vehicle unit comprising a first vehicle component, a second vehicle component and a rolling support device that offsets the gap between the first vehicle component and the second vehicle component. Rolling motion about a roll axis. The rolling support device includes a torsion bar, a first torsion arm and a second torsion arm. The first torsion arm is rotationally rigidly connected to the first end of the torsion bar and is joined to the first vehicle member, and the second torsion arm is rotationally rigidly connected to the first end of the torsion bar. The two ends are also joined to the first vehicle component. Furthermore, the torsion bar is pivotably mounted to the second vehicle component by means of a first support element and a second support element, wherein the mutual distance between the first support element and the second support element is: along A support distance on the longitudinal torsion bar ...
