Abstract
A chassis for a rail vehicle includes at least one chassis frame to which at least one first wheel set and a second wheel set are coupled and to which at least one first drive unit and a second drive unit are connected, wherein a first coupling rod is connected at least to the first drive unit in an articulated manner and is configured to be coupleable to the vehicle body of the rail vehicle in an elastic manner, such that advantageous structural conditions are achieved.
Claims16
A chassis of a rail vehicle, comprising:
- at least one chassis frame;
- at least a first wheelset and a second wheelset coupled to the at least one chassis frame;
- at least a first drive unit and a second drive unit connected to the at least one chassis frame;
- a first coupling rod connected in an articulated manner to the at least first drive unit and being rotatable about a joint axis arranged transversely with respect to a horizontal plane, the first coupling rod being configured to be coupled in a sprung manner to a wagon body of the rail vehicle;
- wherein the at least first drive unit is connected to the at least first wheelset via a coupling such that the at least first drive unit is displaceable in a direction of a chassis transverse axis, and the at least first drive unit is connected via a first bearing apparatus to a first crossmember of the at least one chassis frame in a sprung manner and such that the at least first drive unit is movable in the direction of the chassis transverse axis, and the at least first drive unit is connected via a second bearing apparatus to a second crossmember of the at least one chassis frame in a sprung manner and such that the at least first drive unit is movable in the direction of the chassis transverse axis, the at least first drive unit being mounted such that the at least first drive unit is rotationally movable about a drive vertical axis which is displaceable in the direction of the chassis transverse axis.
