Definitions

  • the invention relates to an air spring control arrangement for a rail vehicle with at least one car body and at least one chassis, wherein the air spring control arrangement has at least one air spring valve and at least one air spring linkage.
  • a height adjustment of car bodies of rail vehicles with air springs is often based on a measurement of distances between the car body and a chassis frame of the rail vehicle.
  • a length-adjustable air spring linkage is used, which is connected at one of its ends to the chassis frame and at its other end with a lever or is mounted articulated on the air suspension valve.
  • a proportional valve is controlled, which causes a drop of the air spring with compressed air falls below a defined threshold distance and escape when exceeding a defined limit distance compressed air from the air spring.
  • About the length adjustability of the air spring linkage whose nominal distance is set.
  • the air spring linkage can assume different positions due to rolling, pitching and turning movements of the chassis or the car body, ie as a spring operations, ie, for example Jounce or lowering the car body relative to the chassis along a vertical axis of the chassis can be misinterpreted.
  • a spring operations ie, for example Jounce or lowering the car body relative to the chassis along a vertical axis of the chassis can be misinterpreted.
  • the air spring valve opens and closes even if no height adjustment is required. This can, for example, incorrect vertical distances between a platform edge and a floor area in the region of a door effect of the rail vehicle. Furthermore, this can lead to increased air consumption.
  • the AT 503 256 B1 known. It describes an electronic air spring control to reduce the air consumption of an air spring and for a quick height adjustment.
  • a switching means is arranged, with which an air flow from and to the air spring can be controlled.
  • it is possible to interrupt the flow of air when no height adjustment is required eg, relative movements between a car body and a chassis that occur during cornering and can be misinterpreted by the air spring control as suspension operations for which height adjustment is required).
  • a method for controlling an air spring arrangement of a vehicle is shown in which detects conditions of the vehicle and from a required height regulation behavior for an air spring is derived.
  • Condition parameters of the vehicle are combined into parameter sets, with each parameter set being assigned a defined height regulation behavior.
  • On the basis of these parameter sets at least one valve of the air spring is controlled, via which a corresponding height regulation behavior is set.
  • the invention has for its object to provide an improved over the prior art air spring control arrangement.
  • this object is achieved with an air spring control arrangement of the type mentioned, in which the at least one air suspension valve is mounted on the at least one chassis and at least on the at least one Air spring linkage is connected to the car body in such a way that are transmitted from the at least one air spring linkage relative movements between the at least one car body and the at least one suspension on the at least one air suspension valve, which are unique Federungsvorêtn between the at least one car body and the at least one chassis can be assigned ,
  • the air spring linkage is pivotally mounted, for example in the middle of a torsion bar of a roll system, which is connected to the car body and with the chassis, and with the air suspension valve mounted on the landing gear about a transverse axis of the chassis.
  • the connection of the air spring linkage with the torsion bar via a roll adapter. Due to the bearing of the roll system and the air spring valve and the connection of the air spring linkage with the roll system and the air suspension valve relative movements between the car body and the chassis, which should not be misinterpreted as suspension operations (eg rolling), not transmitted via the air spring linkage to the air suspension valve.
  • the air spring valve opens or closes during suspension operations and is decoupled from relative movements between the car body and the chassis, for which no height adjustment is to take place.
  • a great robustness is achieved because the decoupling is direct and mechanical, ie no switching means, etc. are required for the processing of position and position information of the car body and the chassis or the air suspension control arrangement.
  • no complex air spring control is required in this context, in which a height adjustment on the basis of defined parameter sets that describe a vehicle behavior, takes place.
  • the at least one air spring linkage is designed to be adjustable in length.
  • the air spring linkage 2 is connected via the lever 3 in a plane which is spanned by a longitudinal axis 20 and a vertical axis 21, pivotally connected to the air spring valve 1.
  • the air suspension valve 1 is connected via a second chassis adapter 16 with a chassis of the rail vehicle, not shown.
  • the air spring linkage 2 is adjustable in length via a cylinder arranged centrally thereon and connected to a roll system 4 via a roll adapter 5. About the length adjustability of the air spring linkage 2, a nominal distance between the air spring valve 1 and the roll system 4 is set.
  • the roll adapter 5 has a tubular part and a cuboid part. About the cuboid part of the air spring linkage 2 is pivotally mounted on the roll adapter 5 in the plane defined by the longitudinal axis 20 and the vertical axis 21 plane.
  • the pivotable mounting of the air spring linkage 2 is a fifth swivel joint 27 arranged between the roll adapter 5 and the air spring linkage 2, a sixth swivel joint 28 provided between the air spring linkage 2 and the lever 3, and a seventh swivel joint 29 which is located between the lever 3 and the air spring valve 1 is arranged achieved.
  • the tubular part of the roll adapter 5 is mounted with its center in a connecting part center 10 of a torsion bar 6 of the roll system 4.
  • An inner circumferential surface of the roll adapter 5 contacts an outer circumferential surface of the torsion bar 6.
  • the torsion bar 6 comprises a first side part 7 and a second side part 8, which run parallel to the longitudinal axis 20 in the illustrated state of the roll system 4 a connecting part 9, which runs along a transverse axis 22.
  • the transitions between the connecting part 9 and the first side part 7 and the second side part 8 are arcuate.
  • the torsion bar 6 is mounted on the chassis via a first rolling bearing 11 and a second rolling bearing 12, which are arranged on the connecting part 9.
  • the first rolling bearing 11 and the second rolling bearing 12 are designed tubular. Your inner lateral surfaces touch the outer circumferential surface of the torsion bar. 6
  • the connection between the first roll bearing 11 and the chassis via a first chassis adapter 15 the connection between the second roll bearing 12 and the chassis
  • the first side part 7 has at its free end a second pivot 24, the second side part 8 at its free end a fourth pivot 26.
  • a lower end of a first Buchyakstabs 13 is connected to the fourth pivot 26, a lower End of a second tension bar 14.
  • An upper end of the first Glastownstabs 13 is connected via a first pivot joint 23 with a arranged on a lower side of the car body first car body adapter 18, an upper end of the second Wertowns 14 via a third rotary joint 25 with a likewise arranged on this Unterseites the car body second car body adapter 19th ,
  • the roll system 4 carries out, for example, pivoting movements in a plane spanned by the longitudinal axis 20 and the vertical axis 21 and planes parallel thereto, which are relative movements between the vehicle body and the chassis. Relative movements in other planes are due to the described storage of the air spring control arrangement only in a negligible for a functioning of the air spring control arrangement according to the invention in Swivel movements of the air spring linkage 2 and the lever 3 implemented.
  • This kinematic behavior causes only relative movements due to springing events of the rail vehicle, i. Lowering and lifting operations between the car body and the chassis occur along the vertical axis 21, are transmitted to the air suspension valve 1, or other relative movements (eg rotations about the longitudinal axis 20 or an axis parallel thereto due to rolling operations, rotations about the vertical axis 21 or a parallel axis due to Auscardvorticiann etc.) lead to negligible extent to reactions of the air suspension valve 1.
  • the connecting part 9 of the torsion bar 6 rotates about the transverse axis 22 or about an axis parallel thereto.
  • the roll adapter 5, the air spring linkage 2 and the lever 3 pivot, the air spring linkage 2 executing an arcuate translation.
  • This movement is transmitted via the lever 3 to the air spring valve 1.
  • the rotation of the lever 3 is converted in a manner known from the prior art in an opening or closing operation of the air spring valve 1, which is designed as a proportional valve, and it is thereby controlled an air flow from or into an unillustrated air spring known embodiment , In this way, height adjustment of the rail vehicle is performed.
  • the roll adapter 5 as a potentiometer.
  • angle and displacement measurements are performed when converting from rotational to translational motion.
  • Information about measured angles and paths can be processed by an air spring control and an air pressure in the air spring can be controlled based thereon.
  • the air spring control arrangement according to the invention can be used in different rail vehicles (eg in metros or subways, in high-speed multiple units, etc.).
