Abstract (en)

[origin: WO2019185119A1] 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 wheelset, 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 wheelset 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 wheelset 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 wheelset 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.
