Definitions

  • the invention relates to a vehicle according to the preamble of the first claim.
  • connection device which has a hydraulic actuator with a Piston and a cylinder housing as the actuating means, the axial only straight are adjustable against each other.
  • the cylinder housing and the piston or with it connected piston rods are each provided with a uniaxial joint, whereby one joint with the car body and the other joint in at least largely vertical assignment articulated below on the chassis frame of the chassis are.
  • the actuator is used to control the body level.
  • a disadvantage is this structure that special for the failure of hydropneumatics Support elements must be provided, which are fixed at both ends Relieve the pressure on the actuators completely after they have been used without external support Joint connector can tilt, causing an impermissible displacement of the Car body can come opposite the chassis.
  • the invention has for its object in a vehicle according to the preamble of the first claim to take measures by means of which connecting means also Failure trap take over the necessary support function.
  • Connecting device a support member in which the actuator is always in a vertical assignment to one of the two vehicle parts is held.
  • translational degrees of freedom only in one plane that is parallel to the plane runs on which the connecting element (s) are fixed.
  • the Connection devices are perpendicular to the plane on which they are fixed. In the event of failure of the electrically driven hydraulic cylinder
  • the actuator can thus have a spindle arrangement or the like do not swing towards the part of the vehicle on which it is fixed.
  • the minimum axial length of the actuator determines the distance between those to be spaced apart and movable against one another within predetermined limits Vehicle parts.
  • the necessary swivel movements are in the Connection device integrated joint connection added.
  • the Articulated connectors designed in the manner of a universal joint, cardan joint or ball joint, while the sliding connector in its translational mobility by attachment appropriate stops on what is necessary for the operation of the rail vehicle Dimension is limited.
  • the connecting device thus consists of a mechanically functional Series arrangement consisting of the actuator, one only in one plane adjustable sliding connector and a trained in the manner of a ball joint Joint connector exists.
  • This connection device includes the variable length actuator an element for the simultaneous limitation of the Height distance between drive and car body and with the motion-limited sliding connector a functional element solely for limiting the Movement between the two vehicle parts in the direction of travel or transversely to it. moreover leaves the joint connector only the inclinations or occurring during operation Twists between the levels specified by the vehicle parts.
  • each different degrees of freedom for the movement between the vehicle parts enable, movable members of two of the components can rigidly with the two vehicle parts are connected, so that each of the third component the link between the second adjustable links of the fixed Forms components.
  • only the stroke of the respective actuator is available available for height adjustment between the drive and car body and only The car body can sink as far as this by the stroke towards the drive, after neither the hinge connector nor the slide connector has any movement in it Allow direction and the longitudinal axis of the actuator is not opposite one of the Vehicle parts can be tilted.
  • the invention is based on schematic diagrams of an embodiment explained in more detail.
  • a vehicle body 1 is of a vehicle, in particular a rail vehicle schematically indicated, under the bottom wall 2 a drive is arranged.
  • the Drive has at least one axis or two wheels 3, in the present case two axes or four wheels 3 on.
  • the wheels 3 are designed as rail wheels.
  • a running gear frame 4 is supported with longitudinal beams 5 running in the direction of travel of the drive, which are connected to one another via at least one cross member 6 by means of Primary spring 7 on wheel bearing elements 8 of the wheels 3 and thus couples the wheels 3 stable running among themselves.
  • Approximately in the middle of two in a row in the running direction arranged wheels 3 is on each side member 5 perpendicular to the through them Frame 5 formed level on each of the frame 5 a Connection device via which the car body 1 with its bottom wall 2 the drive is supported.
  • the connecting device consists of an actuator 9, one in all directions tiltable joint connector 10 and a sliding connector 11, which in the Direction of action of the actuator 9 are arranged mechanically in series.
  • the hinge connector 10 can be used as a universal or ball joint, as a rubber-elastic joint or in the manner of a Spring rod to be designed to only pivot movements with limited To be able to perform swivel deflection in all directions
  • the sliding connector 11 only has translational degrees of freedom in a plane that is parallel to the bottom wall 2 the car body 1 is.
  • the displaceability in one plane that is not tied to any direction this sliding connector is limited to predetermined values.
  • the assignment of the individual components 9, 10, 11 of the connecting device has the effect that only the actuator distance differences between the bogie 4 and the car body 1 can compensate that the hinge connector 10 only direction-independent Can compensate for tilting movements and that the sliding connector 11 is only transverse to Compensate the adjustment direction or movements directed towards its adjusting axis can. It is independent of the principle in which order the Components 9, 10, 11 are joined together when the two ends are in each case Components on the one hand on the chassis 4 and on the other hand on the car body 1 are fixed.
  • the cylinder housing 9.1 is, for example hydraulic actuators 9 with a vertical positioning axis 12 each on a the side member 5 rigidly fixed.
  • the other actuator 9.2 of the actuator 9 is one guided linearly only along the actuating axis 12 in the actuator 9.1 Push rod of the cylinder piston, the free end of this actuator 9.2 with the first swivel link 10.1 of the swivel connector 10 is rigidly connected, while the second pivot member 10.2 with the primary sliding member 11.1 of Sliding element 11 is rigidly connected.
  • the trained as a ball joint Hinged connector 10 only allows tilting movements between those by the Side members 5 and the bottom wall 2 formed levels occur.
  • the primary sliding member 11.1 with the second Swivel member 10.2 of the articulated connector 10 and its secondary sliding member 11.2 in is firmly connected to the bottom wall 2 of the car body 1.
  • the actuator 9 can replace spring elements in this structure, which as Secondary suspension act.
  • it is particularly operated as a hydropneumatic Cylinder formed and so does not only allow a height compensation between Car body and bogie frame too, but can also have spring properties have, which otherwise have coil springs, air springs or the like.
  • the power coupling between the body and the bogie to support longitudinal and Shear forces can conventionally z. B. on handlebars, pivot or Lemniscate coupling elements or elastic buffer or spring elements.
  • the connecting device 9, 10, 11 can of course also be dropped between Car body 1 and drive 4 can be installed.
  • the sliding connector 11 without impairing function and security, for example between the respective longitudinal member 5 and the facing actuator 9.1 of the actuator 9 installed become.
  • the secondary link 10.2 is fixed to the body 1 connected.
  • the sliding connector 11 can of course be used can also be installed between the actuator 9 and the joint connector 10.
  • the actuator 9 retains its design variants under all operating conditions vertical position opposite the drive 4 if it is directly on the long beam 5 or connected to it via the sliding connector 11. Does the actuator 9 sit directly or Via the sliding connector 11 on the car body 1, it retains its vertical position compared to the level specified thereby, also under all usual Operating conditions.
  • a rail vehicle constructed in the manner described above is Particularly suitable for the transport of people and fulfills the quality of running high demands.
  • a meaningful transmission path becomes Mass forces from the car body to the bogie frame and opposite the active actuator movements that improve the running quality from the bogie to the Carriage body reached This is done while maintaining the mobility of the Bogie opposite the car body in terms of pitch, roll, Cross swing and turning as well as maintaining the stability of the vertical support if the active spring stage fails and the horizontal centering of the Car body.
  • the structure leads to a stable position of the car body in Regarding the bogie.
  • the car body is therefore stable on the bogies supported, regardless of whether the actuator is active or passive.
  • the drive has an active hydropneumatic secondary suspension in the form of the actuator 9 the same Degrees of freedom like a conventional drive without an active secondary spring. moreover the same degrees of freedom are retained if the active secondary spring fails, which enables an uncomplicated security concept.
