Embodiment Construction

[0033] exist figure 1 The portion of the internally supported chassis of the rail vehicle shown in side view in FIG. 2 includes a chassis frame (not shown) to which a first wheel set and a second wheel set (also not shown) are coupled.

[0034] Set between the first wheel set and the running gear frame: a first wheel set support (not shown), which has a first wheel set support housing 4 or a first rocker arm and a first wheel set guide bushing ( Also not shown); and the second wheel set support, which has a second wheel set support housing or a second rocker arm and a second wheel set guide bushing, also not shown.

[0035] Arranged between the second wheel set and the chassis frame: a third wheel set bearing, which has a third wheel set bearing shell and a third wheel set guide bushing; and a fourth wheel set bearing, which has a fourth The wheel set supporting housing and the fourth wheel set guide bushing are also not shown.

[0036] Furthermore, a first main spring, not ...

Abstract

The invention relates to running gear for a rail vehicle, comprising at least one first drive unit (1), at least one running gear frame and at least one wheel set, wherein the at least first drive unit (1) is supported by means of a first spring device (2) and a second spring device (3) on a first wheel set bearing housing (4) or on a first swing arm and by means of a third spring device and a fourth spring device on a second wheel set bearing housing or on a second swing arm. It is advantageous that at least one first damper device (5), which is arranged between the first wheel set bearing housing (4) or the first swing arm and the at least one drive unit (1), is connected in parallel with the first spring device (2), the second spring device (3), the third spring device and the fourth spring device, said damping device (5) having a damper and, connected in series therewith, a first stop buffer (6) and a second stop buffer (7). This results in a space-saving drive bearing having effective suspension and damping.

Description

technical field [0001] The invention relates to a chassis for a rail vehicle, in particular an internally supported chassis, comprising at least one first drive unit and at least one chassis frame, at least one wheel set by means of a first wheel set support and a second wheel set The two-wheel set support is coupled to the chassis frame, wherein the at least first drive unit is supported on the first wheel set support housing or on the first rocker arm by means of a first spring arrangement and a second spring arrangement, and It is supported on the second wheel set bearing housing or the second rocker arm by means of the third spring device and the fourth spring device. Background technique [0002] In high-speed trains, mechanically decoupling supports for drive units on the running gear of rail vehicles are particularly important, since the strength of dynamic reactions, which e.g. Components transferred to the running gear. The bearing for the drive unit must be desig...
