Definitions
- the invention relates a train set according to the preamble of claim 1, consisting of several rail vehicles, with at least one, with at least one wheel axle and chassis provided with a vehicle body, and with means for electrical or electropneumatic or electrohydraulic influence on the suspension damping.
- chassis damping devices In automotive engineering, electrical or electropneumatic or electrohydraulic controllable chassis damping devices known. However, these serve only to pitch depending on the choice whether the chassis damping is more likely sporty, d. H. hard, or comfortable, d. H. soft, is desired. At Track damping is not alone, however, a question of Driving comfort, but to a considerable extent a question of safety. It goes further for rail vehicles. Vibrations caused by uneven tracks or to be dampened by crossing points. Then this is less a question of comfort rather than a question of security, namely the Trolleys, including the vehicle body, travel safely over such track sections can and prevent derailment.
- EP 0 466 449 A1 shows a train network consisting of several rail vehicles exists, each with at least one chassis, with at least one wheel axle is provided, are equipped. There are also means for electro-hydraulic influencing the chassis damping provided, at least one sensor directly on the chassis is attached, from which chassis accelerations can be determined. Over the across and Undercarriage accelerations determined vertically to the direction of movement also apply to one across and vertically aligned suspension damping. Overall, this allows Solution a generally improved suspension damping. A directional cause-effect relationship this active chassis damping is not specified.
- the invention is therefore based on the object in a chassis for rail vehicles better dampen vibrations that are hazardous to safety.
- the posed Object achieved in that at least directly on the chassis a sensor is arranged, from or from which chassis accelerations can be determined.
- the sensor is like this attached that accelerations substantially parallel to the impeller axis can be determined.
- the actuator leads in the lateral offset direction of the bogie for damping, however, a movement perpendicular to the impeller axis, d. H. in the vertical out. That is, in the present invention are damping or lifting or adjusting direction perpendicular to the direction in which the acceleration is measured.
- a advantageous embodiment of the invention in addition to the vertical stroke a essentially parallel and / or anti-parallel to the direction of travel horizontal stroke is provided, makes use of so-called anti-roll devices.
- the sensor is based on the principle of inertia Acceleration sensor, from which a directly proportional to the acceleration Measured variable is also obtained in a further advantageous embodiment electronic means are available, with the aid of which the driving behavior is determined and / or is recordable, and that with the help of electronics control signals to influence the Suspension damping can be generated.
- FIG. 1 shows a chassis of a rail vehicle using the first variant according to the invention.
- An acceleration sensor 3 is located directly on the chassis 1 arranged. This acceleration sensor measures accelerations in the essentially parallel to the impeller axles 2.
- the acceleration sensor is in terms of its generated electrical quantity proportional to the acceleration connected to electronics 10 which in turn are connected to a car and / or Train diagnosis unit 20 can be connected. From this train diagnosis 20 or from the electronics 10 becomes dependent on the acceleration signal and possibly depending on the selected driving programs, the actuator 5 one Damping device consisting of actuator 5 and shock absorber 4 controlled.
- FIG 2 shows one advantageous embodiment of the invention, at the in the same an acceleration sensor 3 on a chassis 1 of a Rail vehicle is attached.
- This is a typical one innovative high-speed chassis.
- this gooseneck bogie of Figure 2 is in itself more elastic than the system shown in Figure 1 with fixed axle bearing guides.
- the invention is advantageously used in that the Acceleration sensor 3 essentially accelerations parallel or anti-parallel to the barrel axes.
- the output signal of this acceleration sensor 3 is as in Figure 1 also an electronics and / or a car or Train diagnosis unit 20 supplied. Out of this then the Anti-roll damper 5 'controlled in a corresponding manner. Even with this system is the pitch direction of the roll damper 5 'substantially perpendicular to the Direction in which the accelerations are measured, d. H. essentially perpendicular to the measurable acceleration vectors.
- Figure 3 shows the measurement and control integration of the system in a Electronics or in a train diagnosis system.
- the sensor 3 is, for example, an after The principle of inertia working sensor, in which the Deflection of a membrane with mass is measured. It would also be a Sensor conceivable that essentially consists of only one deflection measuring element consists of which by the 2nd temporal derivation of the place after the time the acceleration is formed.
- the sensor 3 is on the output side a transducer 11 connected to a processed electrical signal on Output to an amplifier 12 there.
- the output of the amplifier is with a Low pass 13 connected, the high-frequency interference or vibrations from the System should take out and only signals that come from low-frequency Faults result in the evaluation computer 14 should pass on.
- evaluation computer 14 is also provided with a diagnosis computer 21 connected, which also receives the unfiltered transducer signal.
- This Diagnostic computer 21 is in bilateral data flow with a monitor 23, the for example, can be installed in the towing vehicle. Furthermore points in this Embodiment of the diagnostic computer 21 has an interface 22 which with the So-called train bus is connected, via which the acceleration sensor signals all bogies or all bogies taken together in an addressed manner can be, and possibly also control signals in addressed form to the Damper devices of the chassis can be given to which the occurring vibrations must be damped.
