Definitions

  • the invention relates to an entry for rail vehicles according to the preamble of claim 1.
  • Such entrances are used for easy changing of passengers from a passenger waiting area to the level of the vehicle floor.
  • Rail vehicles are known in which a step can be swung out in order to facilitate boarding. It is not possible to adapt to passenger waiting areas of different heights.
  • CH-421 723 provides a three-stage entry for three different platform heights for public transport.
  • the lower step can be pivoted out separately with respect to the outer skin of the vehicle, and the upper step can be lowered or swiveled out, while the middle step is fixed.
  • the distance between the outer skin of the vehicle and the platform must be specified. Simultaneous adaptation to different, in particular larger, distances is not possible.
  • FR-A-2 534 202 discloses a multi-stage ladder for facilitating the entry of vehicle treads.
  • the side rails of the ladder are mounted on the top in link guides, which are attached to the chassis of the vehicle. The In this way, the ladder can be extended and retracted as a complete unit to bridge the height between the road and the tread.
  • the steps of the ladder are fixed relative to each other.
  • the object of the present invention is to provide an entry for rail vehicles which can be adapted to platforms or passenger waiting areas of different heights and different distances between the platform and the vehicle outer skin.
  • the invention enables adaptation to different distances and different heights at the same time, in particular for the upper level.
  • a sliding-pivoting stage or a similar construction can also be used for lower stage 1.
  • the second (middle) stage 2 for situations Ia, Ib and IIa ends with a three-stage entry with its front edge approximately with the vehicle outer skin 6. It is rigidly connected to the body or is designed to be extendable. The height above the top edge of the rail is approx. 63 cm, cf. 1 and 2.
  • the lower stage 1 can be extended and the upper stage 3 can be extended and retracted.
  • the second stage 2 With a four-stage entry, the second stage 2 also closes with the front edge of the vehicle outer skin for situation Ia, cf. Fig. 6, while for situation IIb, the bottom and the second stage 1 and 2 complete with the vehicle outer skin, cf. Fig. 7.
  • the lowest stage 1 is extendable, the two middle stages 2 and 2 'are fixed, and the upper stage 3 is designed to be retractable and extendable.
  • Steps 1 and 2 are extendable, and the upper step is retractable and extendable.
  • the second stage remains concealed for situations Id and IIb (elevated platforms), cf. 3 and 4.
  • the lowest stage 1 is extendable
  • the middle stage 2 is fixed or extendable
  • the upper stage is retractable and extendable.
  • the lower stage 1 can be extended, the two middle stages 2 and 2 'are fixed or retractable, and the upper stage 3 is designed to be retractable and extendable.
  • Upper level 3 located approximately at the level of vehicle floor 5 (87 cm above the top edge of the rail), is a horizontal sliding level with the following positions and tasks: Basic position, position while driving and entry situation on elevated platforms according to FIGS. 3, 4 and 8.
  • the front edge of the upper step 3 ends with the vehicle outer skin 6 and has the function here as part of the vehicle floor and appearance for entry, s. 3 and 8.
  • the upper step 3 is pulled back under the vehicle floor 5 and releases the middle, rigid step 2 or the two middle fixed steps 2, 2 ', cf. Fig. 1, 2, 6 and 7.
  • the vehicle floor here takes over the function of the upper stage (appearance) while simultaneously extending the lower, first stage 1 for situations Ia; Ib and IIa, cf. 1, 2 and 6.
  • the lower stage 1 is not extended with a four-stage entry, cf. Fig. 7.
  • the partial element of the vehicle outer skin is attached in the area of the front edge, which covers the gap between the middle and upper step in the basic position, provided that this area is not to remain open.
  • the extension of the upper level for entry situation IIb is used for the permissible remaining gap to the 76 cm EBO platform as well as in connection with the Choice of vehicle floor height chosen for a disabled-friendly entry.
  • the entrance area with the necessary components can be designed as a step box in which all components are permanently installed.
  • this unit includes the drive units, the facial expressions and safety devices. These are shown in more detail in FIGS. 9 and 10.
  • FIGS. 11 and 12 show the alternative design with a separate installation of the movable stages 1 and 3.
  • FIGS. 9 and 10 shows a step box 10 in a sheet steel or steel frame construction, in which the various components such as steps, drives, movement mechanics and safety devices are installed.
  • step boxes 10 are to be regarded as an essential component of a vehicle, since they have a significant influence on the construction of the car body. For example, vehicle side members would have to be pivoted or moved to the center of the vehicle in order to keep the installation areas clear for the complete units.
  • the boxes can be attached to the frame supports or stiffening plates of the car body substructure. In addition to the two movable stages, they also contain the rigid, middle stage.
  • FIG. 9 shows a possible installation situation in a rail vehicle, for example a light rail vehicle.
  • FIG. 11 and 12 show the already mentioned tread area with a modular structure.
  • Each movable stage 1 and 3 with drive, kinematics and safety devices forms a compact, closed unit 24, 26.
  • the entry area contains two different compact units.
  • the middle, rigid stage 2 is an integral part of the vehicle body.
  • FIG. 11 clearly shows the changed installation situation on the vehicle in the modular construction compared to the construction in FIG. 9.
  • Reference numeral 28 denotes a stage 2 trim member attached to the upper stage 3.
  • the lower step 1 In the idle state, the lower step 1 is hidden behind the vehicle outer skin 6 or under the vehicle floor. In the event of an operation, it must be extended and then represents the lowest possible step when entering the vehicle.
  • Level 1 must be motorized from its rest or starting position to a certain height above the top edge of the rail, cf. 1, 2 and 6, are moved directly to the outer skin 6 of the vehicle. It must be sufficiently statically dimensioned to be able to absorb the weight load when changing passengers over a load-bearing width of approx. 1.5 m.
  • the storage and guidance of the stage can be done by means of a lateral guide 20, cf. Fig. 10, or a telescopic pull-out. Rolling bearings, balls or slide rails can be used here at the power transmission points.
  • the use of rotatable, lateral guide struts can be realized, which can be mounted in roller bearings or plain bearing bushes.
  • the stage can reach the operating position in several ways. Three different types of movement are explained below with reference to FIGS. 13 to 21, namely the pushing out, swinging out and unfolding.
  • FIGS. 15 and 16 show the stage 1 in the extended state in a side view and a top view, the reference numeral 40 designating the vehicle outer edge.
  • FIG. 17 shows a top view with stage 1 retracted and FIG. 18 shows a side view with stage 1 extended.
  • stage 1 executes a curved movement 42, which is caused by lateral strut pairs 46 that can be driven by a drive cylinder 44.
  • the stage can be swiveled up or down, whereby both end positions must be monitored, since they are not clearly defined. Here, locking can take place when the respective end position is reached. This is particularly important in the operating position during passenger use. Unintentional lowering must be ruled out.
  • the underside of the step therefore forms part of the outer skin of the vehicle 6.
  • the step is rotatably mounted 47 and, if necessary, is rotated 90 ° away from the vehicle, if necessary that the tread is released for use.
  • the component can be mounted laterally in roller or slide bearings.
  • the movement of the stage can e.g. B. be accomplished by rotating the axis via an electric drive 48.
  • a worm or gearwheel gear 50 which acts on the shaft, can be used, FIG. 20.
  • Another drive option is shown in FIG. 21.
  • the drive 52 acts on components 54 which are located in the extension of the step frame behind the outer skin of the vehicle and are used as a lever arm for power transmission.
  • the end position of the step is determined by limiting the rotary movement. Appropriate dimensioning of the step frame and the bearing bolts enables a structurally sufficiently safe design.
  • the middle step 2 becomes part of the steel frame construction of a step box 10 or part of the vehicle construction, FIG. 11.
  • it is a rigid component, the position of which in the entry area is determined by the boundary conditions described.
  • An advantage of this design is the minimization of the number of moving parts.
  • this makes the structure of the entry area shown only meaningful, since three units with movable steps show no significant advantage over the step box from the point of view of the vehicle construction.
  • the upper stage 3 forms part of the passenger compartment floor 5 in the door area. It is flush with the outside edge of the vehicle, cf. Fig. 3, 22 and 23.
  • the step towards the middle of the car is pulled under the interior floor and then releases the middle step or steps that were previously covered, cf. 1, 2, 6 and 7.
  • the step is pushed outward by a desired amount.
  • Level 3 is extended and in the zero position is the only usable appearance, cf. 3, 4 and 8. Since the step can be pushed under the passenger compartment floor, a threshold which corresponds to the height of the floor structure must be accepted. Below are constructive Possible ways of eliminating them are shown.
  • stage 3 corresponds in width and depth to the other stages 1, 2 and 2 ', cf. 22 and 23.
  • the total depth of step 3 results from the depth of the hidden middle steps 2 (2 ') and the desired extension length 60. This area is covered by the passenger compartment floor 5 in the rest position. Since the step can also be retracted (pull-in length 62), it must be taken into account that there are installation dimensions that can be 40% of the vehicle width. Since entrances can be provided in parallel on both sides of the vehicle, it is clear from this that the units must be as compact as possible.
  • the use of a central drive, which lies between the steps and optionally acts on one of the steps, cannot be ruled out.
  • the drive unit of this stage 3 must be able to move the complete component linearly in two directions from the rest position.
  • a spindle drive with drive motor 56, gear pair 57, spindle 59 and spindle nut 61, cf. Fig. 22 or a gear 58 / rack 63 combination with drive motor 65, cf. Fig. 23 provided.
  • a hydraulic or pneumatic cylinder possibly in conjunction with a lever mechanism. Storage and guidance of the step frame can be ensured, as in step 1, by means of a telescopic pull-out (for the entire step or only for the protruding part) or by means of side link guides 67.
  • the special load due to the cantilevered extension length 60 and the clear entry width of approx. 1.5 m must be taken into account.
  • the end positions (extended, retracted) of the step are delimited the range of motion of the drive mechanism is set with sufficient certainty.
  • the height of the passenger compartment floor structure results from the strength of the materials used and the static requirements. Since the upper step 3 has to be pulled under the floor 5 in certain situations, a threshold at this height is present in the zero position or in the extended state, cf. Fig. 24. The loss of comfort when using the passenger can be caused by bevels of the floor can be reduced.
  • the threshold can be eliminated by partially raising level 3 in the positions mentioned.
  • the step is divided into three parts, an inner part 70, a middle part 72 and an outer part 74, of which the outer part 74 and the inner part 70 are rotatably supported 76, 78 in the rigid step frame at their front ends and are designed to be liftable at their rear ends by the lifting device 80.
  • FIGS. 24 to 26 show the possibilities of overcoming the difference in level between the surface of step 3 and the passenger compartment floor when the rest position, FIGS. 24 and 25, or when the step is extended, FIG. 26.
  • the reference numeral 82 denotes a rigid step frame.
  • step 3 Another way to minimize the threshold is to reduce the floor thickness.
  • the vehicle floor in the middle of the steps would have to be supported. It would be conceivable to hang the floor in the entry area via a central pole or with a support in the middle of the step, although step 3 would have to be slotted.
