Embodiment Construction

[0040] FIG. 1 shows a three-axle running gear 3 for a rail vehicle, such as a three-axle bogie or three wheel units in the form of a wheel set or a wheel set, which are attached to the car body. It has a bogie frame or carbody frame, not shown in Figure 1, consisting of longitudinal and cross beams. On the longitudinal beam, the wheel bearing boxes 2 to 7 of the three wheel units 8, 9, 10 are fixed by elastic members not shown, and the wheel bearing boxes 2, 3 are used for the first wheel unit 8 (outer wheel unit), the wheel The bearing housings 4, 5 are for the second wheel unit 9 (middle wheel unit) and the wheel bearing housings 6, 7 are for the third wheel unit (outer wheel unit). The wheel unit 8 , 9 , 10 includes a wheel 11 . The wheel units 8, 9, 10 can be driven by unrepresented drive motors, such as axle-wrapped suspension traction motors or fully suspended traction motors.

[0041] The wheel bearing housings 2 , 3 , 6 , 7 of the two outer wheel units 8 , 10 move pr...

Abstract

The invention relates to a method for active radial control of the wheels (11, 53, 103, 108, 115) of at last one wheel unit (8, 9, 10, 51, 52) on a chassis, in particular a bogie on a tracked vehicle, whereby control movements are applied to the wheel unit (8, 9, 10, 51, 52) and an integrated regulation with control movements in at least two non-identical frequency ranges are carried out. First control movements in a first frequency range and second control movements in a second frequency range, different form the first frequency range are superimposed and applied to the wheel unit (8, 9, 10, 51, 52). The invention also relates to a device for carrying out the method.

Description

technical field [0001] The present invention relates to a method and a device for active radial control of a wheel set or wheel set for a vehicle. The invention is particularly suitable for use in rail vehicles, but is not limited thereto. Background technique [0002] A series of mechanical devices are known, with passive or active means, for the quasi-static adjustment of wheelsets or wheelsets, hereinafter collectively referred to as wheel units, within railway curves. During active control, the wheel units are adjusted and fixed according to the radius of the curve. These devices control the wheel units in a fixed relationship to the radius of the curve and at most achieve an equal sum of the transverse forces acting on the wheel units of the vehicle running gear to a limited extent. The disadvantage here is that the driving stability is no better than in a conventional chassis with a rigid longitudinal guide of the wheel unit; at most it is not worsened. Mechanical d...
