Embodiment Construction

[0029] FIG. 1 shows a running gear 1 according to the invention for a three-axle bogie of a railway vehicle. This running gear has a bogie frame (not shown in FIG. 1 ) consisting of longitudinal beams and transverse beams.

[0030]The wheel set bearing housings 2 to 7 of the three wheel sets 8, 9, 10 are fastened to the longitudinal beam by means of a spring element not shown, and the wheel set bearing housings 2, 3 are used for the first wheel set 8, at In the following it will be referred to as the first outer wheel set, the wheel set bearing housings 4, 5 for the second wheel set 9, which will be referred to below as the middle wheel set, and the wheel set bearing housings 6, 7 for the third wheel set Pair 10, which will be referred to below as the second outer wheel set. Said wheel sets 8 , 9 , 10 comprise working wheels 11 . The wheel sets 8 , 9 , 10 can be driven by drive motors (not shown), for example longitudinal bearing traction motors or frame motors.

Abstract

The invention relates to a self-steering, three-axle bogie, in particular for a rail vehicle, comprising wheel sets (8, 9, 10) and wheel set bearing housings (2, 3, 4, 5, 6, 7) allocated to said sets. According to the invention, the outer wheel sets (8, 10) are counter-coupled and can be displaced in a longitudinal direction and the central wheel set (9) can be displaced in a transverse direction and is included in the control system. The wheel set bearing housings (2, 4, 6) on one side of the running gear and / or the wheel set bearing housings (3, 5, 7) on the other side of the running gear are coupled exclusively to the wheel set bearing housings (2, 3, 4, 5, 6, 7) lying on the same side and neighbouring wheel set bearing housings (2, 3, 4, 5, 6, 7) are coupled to a first rotary lever (14, 26) that is connected so that it can rotate to the corresponding wheel set bearing housing (4, 5) of the central wheel set (9), by means of a steering linkage-rotary lever configuration.

Description

technical field [0001] The invention relates to a self-steering, three-axle bogie, in particular for railway vehicles, with wheelsets and associated wheelset bearing housings, wherein the outer wheelsets are countercoupled and displaceable in the longitudinal direction and the middle wheelset Can move laterally and participate in a control system where the wheelset bearing housing on one side of the undercarriage and / or the wheelset bearing housing on the other side of the undercarriage are only compatible with the wheelsets on the same side of the undercarriage Bearing housing coupling. [0002] The invention is particularly applicable to railway vehicles, especially locomotives. However, the invention is not limited to this application. Background technique [0003] A self-steering, three-axle bogie for the self-steering of railway vehicles is known, for example, from DE 38 24 709 C2. A disadvantage of such bogies is that the central wheel pair does not take part in the...
