Definitions

  • the invention relates to a chassis for rail vehicles, consisting of a chassis provided with at least one wheel axle and a vehicle body, and with means for electrically or electropneumatically or electrohydraulically influencing the chassis damping.
  • Chassis damping devices which can be influenced electrically or electropneumatically or electrohydraulically are known in automobile construction. However, these are only used to set the cans, depending on the choice, whether the chassis damping is more sporty, ie hard, or comfortable, ie soft. In the case of rail vehicles, however, chassis damping is not alone, a question of driving comfort, but to a large extent a question of safety. Rail vehicles are also involved. To dampen vibrations that are caused by uneven tracks or by crossing switches. This is less a question of comfort than a question of safety, namely to be able to safely drive the bogies and the vehicle body over such track sections and to prevent derailment.
  • the invention is therefore based on the object of better damping vibrations which endanger safety in a chassis for rail vehicles.
  • the object is achieved according to the invention in that at least one sensor is arranged directly on the chassis, from which or from which chassis accelerations can be determined.
  • the sensor is therefore mounted in such a way that accelerations can be determined essentially parallel to the impeller axis.
  • the actuator for damping executes a movement perpendicular to the impeller axis, ie in the vertical direction. That is, In the present invention, the damping or lifting or adjusting direction is perpendicular to the direction in which the acceleration is measured.
  • damping only appears efficient and effective if the actuating stroke of the damping device is also parallel or anti-parallel to the direction in which the vibrations or deflections are measured.
  • the compensation stroke is always in the plane in which the deflection is located, preferably parallel or antiparallel to it.
  • this damping system is solved in a completely new manner by determining the transverse accelerations on the chassis, that is to say the accelerations parallel to the wheel axis, and the actuating stroke triggered thereon, however, being perpendicular thereto, that is to say, for example, in the vertical direction.
  • a second variant of the invention in which the damping is set essentially parallel and / or antiparallel to the direction of travel, makes use of so-called anti-roll dampers.
  • the principle according to the invention is also applied here.
  • the sensor is one that works on the principle of inertia Acceleration sensor, from which a measurement variable which is directly proportional to the acceleration is obtained.
  • electronic means are available, with the aid of which the driving behavior can be determined and / or recorded, and that the electronics can be used to generate actuating signals for influencing the chassis damping.
  • FIG. 1 shows a chassis of a rail vehicle using the first variant of the invention.
  • An acceleration sensor 3 is arranged directly on the chassis 1.
  • This acceleration sensor measures accelerations essentially parallel to the impeller axles 2.
  • the acceleration sensor is connected to an electronic unit 10 in terms of its generated electrical quantity proportional to the acceleration, which in turn can be connected to a car and / or train diagnosis unit 20. From this train diagnosis 20 or from the electronics 10, depending on the acceleration signal and possibly depending on selected driving programs, the actuator 5 of a damping device consisting of actuator 5 and shock absorber 4 is controlled.
  • FIG. 2 shows a second variant according to the invention, in which an acceleration sensor 3 is attached to a chassis 1 of a rail vehicle in the same way according to the invention.
  • This is a typical new high-speed chassis.
  • this gooseneck bogie of Figure 2 is inherently more elastic than the system shown in Figure 1 with fixed axle bearing guides.
  • anti-roll dampers which have their actuating stroke or their direction of attack essentially parallel or antiparallel to the direction of travel.
  • the invention is advantageously used in that the acceleration sensor 3 essentially measures accelerations parallel or antiparallel to the running axes.
  • the output signal of this acceleration sensor 3 is also supplied to electronics and / or a car or train diagnosis unit 20. From this, the roll damper 5 'are then activated in a corresponding manner. In this system too, the direction of inclination of the roll damper 5 'is essentially perpendicular to the direction in which the accelerations are measured, i. H. essentially perpendicular to the measurable acceleration vectors.
  • Figure 3 shows the measurement and control integration of the system in electronics or in a train diagnosis system.
  • the sensor 3 is, for example, a sensor working according to the principle of inertia, in which the deflection of a membrane with mass is measured in a capacitive manner.
  • a sensor would be conceivable, which essentially consists of an element measuring only a deflection, from which the acceleration is formed by the second time derivation of the location over time.
  • the sensor 3 is connected on the output side to a transducer 11, which outputs a processed electrical signal to an amplifier 12 at the output.
  • the output of the amplifier is connected to a low-pass filter 13, which is intended to take high-frequency interference or vibrations out of the system and only signals which result from low-frequency interference are to be passed on to the evaluation computer 14.
  • the 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, which can be installed, for example, in the towing vehicle.
  • the diagnostic computer 21 has an interface 22, which is connected to the so-called train bus, via which the acceleration sensor signals of all bogies or all undercarriages can be combined in an addressed manner, and possibly also control signals in an addressed form to the damper devices of the undercarriages can be given at which the vibrations that occur must be damped.
