    description
    Rail vehicle with covered landing gear Technical area
    The invention relates to a rail vehicle with a covered chassis, in particular bogie, wherein the cladding comprises at least side elements which are arranged laterally of the chassis along the rail vehicle, and a bottom element, which is arranged on the underside of the chassis.
    The invention is applicable to bogies, in particular to internally mounted bogies, where the axle bearings and the frame parts are located between the wheels or wheel discs.
    State of the art
    The driving resistance of trains, especially high-speed trains, is very much determined by the aerodynamic driving resistance. This aerodynamic driving resistance contains a relevant portion of the resistance of the underbody of the rail vehicle, in particular the free spaces, which are necessary for the movement of the undercarriage chassis. Also for the acoustic properties of rail vehicles, these spaces are disadvantageous.
    In order to achieve improvements in this regard, it is known to attach aprons on the side of the bogie of the rail vehicle.
    Moreover, it is known from WO 2010/086201 Al, the lining as a circumferential wall for embracing the bogie and a fastening means for rotating the rotating wall at its upper edge on a car body of the rail vehicle form such that the rotation of the rotating wall respectively corresponds to the rotation of the bogie; the panel is covered at the lower edge of the peripheral wall by means of a subfloor-like closure member having attachment means for attachment to the bogie. Here, the aprons are so designed to be rotatable relative to the car body, as well as the bottom-like end part is connected to the axle box or bogie frame.
    WO 2012/069269 A1 also shows a rail vehicle with a clad chassis, where the lateral cladding elements follow the movement of the bogie and form a one-piece full cladding of the bogie with a floor element.
    The well-known, laterally mounted on the bogie of the rail vehicle skirts disregard the aerodynamic properties of the underside of the chassis, the rotatable side paneling elements with equally rotatable bottom element require a complex suspension of the lateral lining elements and reduce the running stability due to their relatively high mass moments of inertia about the vertical axis of the chassis ,
    Presentation of the invention
    It is therefore an object of the present invention to provide a rail vehicle with a covered chassis, which allows a simple construction of the side elements while covering the underside of the chassis.
    This object is achieved by a rail vehicle with a covered chassis with the features of claim 1, wherein the cladding comprises at least side elements, which are arranged laterally of the chassis along the rail vehicle, and a bottom element, which is arranged on the underside of the chassis.
    It is provided according to the invention that - the side elements are firmly connected to the car body of the rail vehicle, - the bottom element is firmly connected to the chassis and - between the bottom element on the one hand and the side elements on the other hand a gap is provided, both in the untwisted as well in the unwound state of the chassis, a distance between the wheels of the chassis and the bottom element on the one hand and the side elements on the other hand provides. Advantageous embodiments of the invention are defined in the respective dependent claims.
    The fact that the side elements are firmly connected to the car body of the rail vehicle, they can be easily mounted. They can also be structurally simpler in comparison to rotatable side elements because they are exposed to lower accelerations than rotatable side elements. The side panels are usually flush with the side paneling of the entire car body. It may be advantageous that both the side elements and the bottom element are designed for maintenance easy disassembled or hinged.
    The side elements otherwise close - outside the distances according to the invention - in the longitudinal direction before or after the wheels with the lining of the rail vehicle, the movement-related distances between side elements and wheels or base plate are thus in the flow or direction of travel through the previously arranged areas of the side elements fluidly shielded.
    The connection of the side elements with the car body, the side elements also have no negative impact on the running stability of the chassis, as fixed parts, they can also be easier and cheaper aerodynamically optimized.
    In one embodiment, the side element may be formed so far pulled down that it covers at least half the wheel surface of the chassis in the side view.
    The floor element aerodynamically seals the underside of the chassis, leaving only enough clearance between the floor element and the side elements to allow the wheels of the landing gear to rotate freely and allow the landing gear to perform all intended movements during operation. This slot-shaped free space is best aerodynamically in the influence of the Radverwirbelung, so that through the gap no additional turbulence of the air takes place at another location. The gap can therefore be arranged in an embodiment largely in addition to the wheels, so outside the wheels.
    Another advantageous design of this clearance is to position the gap in the lee of the wheels, as well as this area is within the influence of the Radverwirbelung.
    Incidentally, it seems advantageous to perform this transverse gap generally in the immediate vicinity of the wheel, as this can be a targeted air supply for the wheels and brakes and thus a corresponding cooling can be realized.
    The bottom element has hardly any disturbing effect on the running stability of the chassis since its mass has a low radius of gyration about the vertical axis relative to a full fairing which is mounted on the bogie.
    In the event that the chassis is a bogie, this may be carried out approximately so that the lower edge of the side members in longitudinal areas, which are closer to the axis of rotation of the bogie, closer to the bottom element come closer than the lower edge in longitudinal regions, which further from the axis of rotation are removed.
    In a biaxial chassis, the lower edge of the side elements between the wheels of different wheel axles can approach closer to the floor element than in the longitudinal area of the wheels, since the axis of rotation of the running gear is located between the wheel axles.
    In particular, in the case of internally mounted undercarriages, provision can be made for the side elements for spring and / or damping elements (such as air springs or rolling damper) to have outward bulges. Otherwise, the cross-section of the side elements in the longitudinal direction for fluidic reasons should not or not change too much.
    Since the car body is often wider than the axle length and connect the side walls flush with the casing of the car body, it may be useful that the side members are curved from the car body down inwards to the bottom element.
    In order to achieve as complete as possible a lining of the chassis, it can be provided that the bottom element has recesses for the wheels and otherwise usually extends in the transverse direction of the chassis to the outside of the wheels. In the case where the gap according to the invention lies largely or even in the slipstream of the wheels, the bottom element is correspondingly shorter in the transverse direction. Then it can be provided that the bottom element has recesses for the wheels and otherwise extends in the transverse direction of the chassis at least to the inside of the wheels. In the height direction, the bottom element is in any case arranged below the wheel axles.
    In the simplest case, the bottom element may be formed as a substantially flat plate, which has, for example, a substantially rectangular shape. The edges of the floor element may also be adapted to the optimum airflow in the area of the gap, e.g. rounded up or angled upwards.
    Furthermore, it can be provided that the bottom element has at least one opening through which components protrude. As components one understands here for example engines, transmissions or bearings. It is thus more space for these components available and the components are cooled by the wind. So that the aerodynamic properties of the soil element are not too much affected by these breakthroughs, the edges of the breakthrough aerodynamically flush with the components can be performed.
    In order to achieve an aerodynamically favorable transition from the floor element to the car body panel, it can be provided that the panel comprises a firmly connected to the car body transition element, which aerodynamically flush the floor element with the
    Car body panel joins. For example, the edge of the floor element in the direction of flow to the car floor may be covered by a ramp-shaped transition element, which ensures a favorable air flow even with all operating spring paths of the chassis.
    In this case, the transition element on that side, which faces the bottom element, be made wider than the bottom element. As a result, a favorable flow is achieved even when the landing gear.
    In the execution of the invention is of course to ensure that the clearance gauge is not violated. As a clearance gauge a defined boundary line is called, which is usually for the vertical transverse plane of a track, here of train tracks, determined. With the
    Clearance profile is on the one hand the "clear space " on the other hand, it also serves as a constructive specification for the design of rolling stock. These must not exceed the prescribed limits in cross-section, whereby it must also be taken into account whether they remain within the clearance profile for particular lengths even in curves. The different
    Vehicle boundary lines are country-specific regulated and are used e.g. for the UIC area by the International Union of Railways in the UIC leaflets. For the boundary lines valid here, the lining according to the invention in combination with an internally mounted chassis represents a particularly advantageous embodiment, since the side elements create particularly well in the longitudinal direction of the contour of the side panel of the remaining car body. Bumps or cutouts in the side elements for the wheelset bearings, as they might be required for externally mounted bogies can be avoided in this case.
    Brief description of the figures
    To further explain the invention, reference is made in the following part of the description to the figures, from the further advantageous embodiments, details and further developments of the invention can be found. Show it:
    1 is a disguised landing gear in a perspective view from the side below,
    2 shows the chassis of FIG. 1 in side view,
    3, the trim parts of Fig. 1 and 2,
    4 is a disguised landing gear in a perspective view from behind bottom,
    Fig. 5 a disguised chassis in the bottom view.
    Embodiment of the invention
    In Fig. 1 a clad chassis is shown in a perspective view from the side below. There are a side member 1, designed as a flat bottom plate bottom element 3 and two transition elements 6 can be seen, which dress the landing gear, which is designed here as a bogie. Not visible here is the side element 1 on the back of the chassis. From the chassis, only the wheels 5 are partially visible.
    The bottom element 3 is substantially rectangular except for the rectangular recesses 7 at its straight longitudinal edges and the circular arc-shaped rounded portions at its ends. The transition elements 6 close on both sides of the bottom element 3, wherein only a narrow annular gap between the circular arc-shaped ends of the bottom element 3 and the likewise circular arc-shaped transition element 6 is present.
    In Fig. 2, where by omitting the car body and the panel another part of the chassis 2 can be seen, it can be seen that the lower contour of the bottom member 3 via the annular gap without displacement in the vertical direction in the lower contour of the transition element 6 continues. The lower contour of the transition element 6 then rises in a ramp shape, in order then to transition as steadily as possible into the underside of the carbody, not shown here.
    The lower contour of the side member 1 increases in the area of the wheels 5 with increasing distance from the axis of rotation of the bogie and falls after the wheels 5 back to the same height as between the wheels 5 from one side. The car body would - seen in the vertical direction - still cover a portion of the wheels 5 above the axles, the car body fixedly arranged side elements 1 then cover an area to below the wheel axles of the wheels 5. The side member 1 is thus pulled so far down that it covers (more than half the area of the two wheels 5 on this side of the chassis 2 (together with the cladding of the car body, not shown here).
    In Fig. 3, only the trim parts 1, 3 and 6 of Fig. 1 and 2 are shown. Already here it can be seen that the lower edge of the side elements 1 in the middle of the bottom element 3 come closer to this than in the region of the recesses 7 for the wheels 5. The width of the gap, which arises between the side element 1 and bottom element 3, widens from the center of the bottom element 3 slowly and then falls after the recess 8 quickly back down to about the dimension in the middle of the bottom element 3 from. This measure is structurally made as small as possible; In any case, it must allow the transverse movements of the bogie.
    The bottom element 3 here in the region of the wheel axles in each case has an opening 4, through which a component can protrude downwards beyond the bottom element 3. The transition from the underside of the bottom element 3 to this component is best formed as possible without a step, so that there is no turbulence here.
    It can also be seen that the bottom element 3 has at its ends a curved longitudinal gap to the car body panel, namely the transition element 6, which has a virtually unchanged gap width when the bogie is rotated, namely by the bottom element 3 at its longitudinal ends as well as the Transition elements 6 at their, the bottom element 3 facing sides arcuate (concentric with the axis of rotation of the bogie) are formed.
    In Fig. 4 the paneled chassis is shown in a perspective view from the rear bottom. It can be seen that the width of the transition element 6 decreases with increasing distance from the bottom element 3 and correspondingly the side elements 1 go further inwards in order to connect directly laterally to the transition elements 6. The gap 8 between the bottom element 3 (and the wheels 5) on the one hand and the side elements 1 on the other hand widens in the direction of travel: between the wheels 5 different wheel axles, the gap 8 is narrower than in the longitudinal region of the wheels 5. Both column 8 (on all four wheels 5) together form an X-shaped course.
    In Fig. 5, the paneled chassis is again shown in bottom view, without the car body.
