    description
    Underfloor device carrier for a rail vehicle.
    Technical field
    The invention relates to an underfloor device carrier for a rail vehicle.
    State of the art
    Underfloor equipment carriers, also called underfloor containers, are very often used in rail vehicles and are used to accommodate electrical equipment, preferably equipment with high energy requirements. They offer the advantage of being able to set up and test these electrical devices separately from the body of the rail vehicle, and they are installed under the body of the vehicle during final assembly. Depending on the type of electrical device arranged in an underfloor container, a certain electrical power loss arises, which is typically dissipated by means of forced-air cooling. Ambient air is sucked in at one point of the underfloor device holder via an air filter, passed over heat-emitting surfaces in the interior of the device holder and released again to the surroundings at another point. Depending on the device to be cooled, the air emitted can have different temperatures. An extreme case are underfloor units with braking resistors, which can reach up to 700 degrees Celsius and cause a very hot exhaust air flow. If this is not a problem even when driving on a free route, / 27
    201803693 this exhaust air can cause problems in bus stops, especially in tunnels. Exhaust air penetrating through the platform gap in the door area represents a loss of comfort for the passengers and can lead to injuries in extreme cases. The warm exhaust air penetrating into the passenger compartment may also have to be cooled again by the air conditioning system. Switching off the ventilation of the devices to be cooled while stopping in a station is not an acceptable option, as braking resistors, for example, require the greatest amount of cooling at this time.
    Presentation of the invention
    The invention is therefore based on the object of specifying an underfloor device carrier for a rail vehicle which avoids the disadvantages of the prior art and at the same time offers the maximum cooling power or cooling air flow provided at any time of operation.
    The object is achieved by an underfloor device carrier for a rail vehicle with the features of claim 1. Advantageous refinements are the subject of subordinate claims.
    According to the basic idea of the invention
    Built-in underfloor device carrier for a rail vehicle, which includes forced ventilation with at least one supply air intake point and at least one exhaust air outlet opening, an air guiding device being provided which can be switched between at least two positions, the exhaust air flowing out in a first outflow direction and in in a first position of the air guiding device / 27
    201803693 a second position of the air guide device, the exhaust air flows out in a second outflow direction.
    This provides the advantage of being able to discharge the exhaust air in a certain direction, so that it can be directed in the direction which is advantageous at the respective time.
    According to the invention, an underfloor device carrier is equipped with air cooling, ambient air being able to be sucked in via at least one supply air suction point, and the cooling air is blown out either in a first or a second outflow direction. For this purpose, an air guiding device is to be provided which effects the corresponding steering of the air flow. This air guiding device can comprise flaps, for example, which are controlled in such a way that they open or close certain paths for the cooling air.
    The outflow directions are advantageously to be oriented such that they blow out the exhaust air in opposite directions. In the installed position of the equipment carrier, it is thereby possible to allow the exhaust air to flow out transversely to the longitudinal direction of the rail vehicle, the exhaust air being blown out only in the opposite direction to the platform during a stop. In this way, an impairment of passenger comfort by hot air emerging from the platform gap, which is particularly important in tunnels, can be prevented.
    The cooling air is typically drawn in either on both sides (based on the long sides of a rail vehicle) or from below, from the direction of the track bed. In / 27
    201803693 In the first case, the exhaust air is blown downwards, in the second case on both sides.
    These two typical embodiments are more well known
    Underfloor device carriers each have particularly advantageous features of an air guiding device.
    If the supply air intake point is provided on the underside of the underfloor unit support and the blow-out takes place via two outlet openings arranged on the side, it is recommended to provide flaps, which alternatively close one of the outlet openings and thus only discharge the cooling air flow through one of the outlet openings. When stopping at a platform, the flap on the platform side is closed; when driving on a free route, both flaps must be opened and the exhaust air must therefore be discharged through both outlet openings.
    In the case of underfloor device holders with side intake air intake points and downward-pointing outlet opening, it is advisable to provide the outflowing air with a transverse component of the speed, i.e. to let it flow out to one side (related to the rail vehicle). For this purpose, for example, air baffles can be provided, which are arranged pivotably in the air flow and thus allow the air flow to exit in a directed manner.
    Another embodiment provides for the outlet opening to be designed in such a way that it has two types of outlet channels, each of which directs the exhaust air in one direction, and to close one type of the outlet channel depending on the desired outlet direction.
    / 27
    201803693
    In a further development of the invention, it is advantageous to place the air-guiding device in a position during travel that forms the lowest flow resistance for the cooling air and thus maximizes the cooling effect.
    The air guiding device is preferably controlled automatically and by means of an electric drive. For this purpose, for example, a control is to be provided, which receives information from the vehicle-side devices (e.g. door control or vehicle control) about the blow-out side to be selected, which is required at the currently approached stop. This control includes those required to drive the air guiding device
    Power electronics and optional means for detecting the operating state of the assigned drives and for detecting errors in these components. It is particularly advantageous to provide a bidirectional data interface via which commands from vehicle-side devices to the control device and status or error messages can be transmitted to the vehicle-side devices.
    A particular embodiment of the invention provides for the air guiding device to be actuated directly mechanically by a door drive or by a drive for bridging a gap. Since in most cases only the doors of one side of the vehicle are opened at a bus stop, a door or gap bridging drive can also open the door or the gap bridging at the same time
    Drive the air baffle of an underfloor device carrier.
    It is particularly advantageous to use the drive of a gap bridging, since this acts before the door is opened and after the door is closed, so that the / 27
    201803693
    Air guiding device is in any case in the correct position before opening the door. The drive force can be transmitted to the air guiding device, for example, by means of a Bowden cable.
    Other forms of a variable cooling air blow-out of an underfloor device carrier can also be realized, however with reduced efficiency and higher manufacturing costs. For example, separate fans and associated air paths to a respective exhaust air outlet opening can be provided for each blow-out direction, which does not require a variable air guiding device, but increases the manufacturing effort.
    Another possibility provides for the cooling air fan to be designed so that it can be reversed, so that the supply air intake point and the exhaust air outlet opening can swap their functions as desired. However, this is not advantageous since conventional fans only have high efficiency in one direction of air delivery, in the opposite direction this is usually extremely low. This could only be solved by using complex fans with blade adjustment.

    Implementation of the invention
    1 shows an example and schematically one
    Underfloor device carrier with a blow-out downwards. A conventional underfloor device carrier 1 is shown, which is arranged on the underside of a rail vehicle 2, which is located in a stop in a tunnel. The underfloor device carrier 1 has two laterally arranged supply air intake points 3, through which in each case supply air 7 is sucked into the interior of the underfloor device carrier 1. The subsequently heated exhaust air 6 is blown out on the underside of the underfloor device carrier 1 via an exhaust air outlet opening 4 and is distributed below the rail vehicle 2, with part of the exhaust air 6 flowing into the space between the rail vehicle 2 and the tunnel wall and another part of the exhaust air 6 through the platform gap 8 in the direction of the platform.
    2 shows, by way of example and schematically, an underfloor device carrier according to the invention with a blow-out downwards on a platform on the left. It is an identical situation as shown in Fig. 1, but with / 27
    201803693 an underfloor device carrier 1 according to the invention is arranged below the rail vehicle 2. Like the underfloor device carrier according to the prior art, this comprises two laterally arranged supply air intake points 3. The exhaust air 6 is discharged via an exhaust air outlet opening 4 on the underside of the underfloor device carrier 1, one of which
    Air guiding device 5 is provided, via which the
    Exit direction of the exhaust air 6 can be predetermined. This
    Air guiding device 5 can be in the form of a plurality of
    Air baffles can be realized, which can each take at least two positions with respect to the air flow and can thus direct it in certain directions. In the exemplary embodiment shown, the air baffles of the air baffle device 5 are set in such a way that the exhaust air 6 flows in the direction of the tunnel wall, that is to say opposite to the platform, and thus practically no portion of the exhaust air 6 passes through the platform gap in the direction of the platform. A drive is provided for moving the air guide plates of the air guide device 5, for example an electric motor, a stepper motor or an electromagnet. Such a drive is not shown to simplify the basic illustration.
    3 shows, by way of example and schematically, an underfloor device carrier according to the invention with a blow-out downwards on a platform on the right-hand side. The exemplary embodiment of an underfloor device carrier 1 from FIG. 2 is shown, the rail vehicle 2 stopping at a stop with a platform on the right-hand side of the vehicle. The air baffles of the air baffle 5 are set so that the exhaust air 6 to the left
    The vehicle's longitudinal axis is blown out and therefore cannot pass through the platform gap 8.
    / 27
    201803693
    When the rail vehicle is traveling, the blow-out direction is irrelevant, the air baffles of the air baffle 5 can therefore be brought into the position required for the next stop during the journey or remain in the last position until the next stop. If the air baffles of the air baffle device 5 are provided with three possible positions, the air baffles can be of the
    Air guiding device 5 are brought into a neutral central position. This can be particularly advantageous if the lowest in this neutral middle position
    Flow resistance of the air guiding device 5 occurs and thus the exhaust air 6 reaches the greatest possible volume flow during the journey.
    4 shows an example and schematically one
    Underfloor equipment rack with a side blowout. A conventional underfloor device carrier 1 is shown, which is arranged on the underside of a rail vehicle 2, which is located in a stop in a tunnel. The underfloor device carrier 1 has a supply air intake point 3 arranged at the bottom, through which supply air 7 is sucked into the interior of the underfloor device carrier 1. The subsequently heated exhaust air 6 is blown out on the sides of the underfloor device carrier 1 via two exhaust air outlet openings 4. Part of the exhaust air 6 flows into the space between the rail vehicle 2 and the tunnel wall, but other part of the exhaust air 6 is blown out directly below the platform gap 8 in the direction of the platform, which is particularly disadvantageous.
    5 shows by way of example and schematically an underfloor equipment carrier according to the invention with a side 9/27 9
    201803693
    Blow-out on a platform on the left. The situation is identical to that shown in FIG. 4, but an underfloor device carrier 1 according to the invention is arranged below the rail vehicle 2. Like the underfloor device support according to the prior art, this includes two exhaust air outlet openings 4 arranged on the side. An air guiding device 5 is provided which comprises two flaps, one flap being assigned to an exhaust air outlet opening 4 and being set up in such a way that it closes the respective exhaust air outlet opening 4 can. The flaps of the air guiding device 5 can preferably be set independently of one another in an open and a closed position with the aid of power. As a result, the outlet direction of the exhaust air 6 can be predetermined, so that, as in the exemplary embodiment illustrated, the exhaust outlet opening 4 on the platform side can be closed and the entire exhaust air 6 exits through the exhaust outlet opening 4 on the tunnel side. A drive is provided for moving the flaps of the air guiding device 5, for example an electric motor, a stepping motor or an electromagnet. to
    Such a drive is not shown to simplify the basic illustration.
    6 shows, by way of example and schematically, an underfloor device carrier according to the invention with a lateral blow-out on a platform on the right-hand side. The exemplary embodiment from FIG. 5 is shown, the flaps of the air-guiding device 5 on the right-hand side of the vehicle being closed during a stop on a right-hand platform, so that the exhaust air 6 is blown out at the tunnel-side exhaust air outlet opening 4. While driving, it is recommended to close all flaps of the air control device 5/27 '
    Open 201803693, as this achieves the best cooling effect for the components to be cooled in the underfloor device holder 1.
    Fig. 7 shows an example and schematically the electrical block diagram of an inventive
    Underfloor device carrier 1. The underfloor device carrier 1 comprises a control device 9 which is set up to operate an electric drive 12. This drive 12 acts on an air guide device 5, so that it is able to set its means for controlling the air flow (flaps or air guide plates) in the respectively required position. Functional monitoring of the air guiding device 5 is provided, in which a position feedback signal 13 is sent from the air guiding device 5 to the control device 9. A malfunction of the drive 12 or the air guiding device 5 can thereby be identified. The
    Control device 9 is connected to a vehicle-side controller 10 by means of a data interface, so that data 11 can be transmitted in both directions between control device 9 and vehicle-side controller 10. Commands to the control device 9 and feedback messages to the vehicle-side control 10 can be transmitted via this data interface.
    8 shows an example and schematically one
    Underfloor device carrier, with a mechanically driven air guide. A section through an underfloor device carrier 1 is shown, which is arranged on the underside of a rail vehicle 2. The rail vehicle 2 is equipped with a gap bridging in the form of a sliding step 14 which can be actuated by means of a sliding step drive 15. The / 27
    201803693
    Underfloor device carrier 1 is constructed according to the principle shown in FIGS. 5 and 6, according to which, alternatively, one of two exhaust air outlet openings 4 can be closed. The
    Air guiding device 5 is accordingly equipped with flaps.
    The sliding step drive 15 acts on the movably mounted
    Footplate and via a power transmission 16 also on the air guide 5 and thus moves the flaps. This power transmission 16 can, for example, as a Bowden cable, as a hydraulic power transmission, or else as
    Rod drive can be executed. In Fig. 8 there is only one
    Half of the underfloor device carrier 1 shown, the other half is constructed in mirror image to the first half.
    The further preferred design of an underfloor device carrier 1 with air baffles arranged in the exhaust air flow can also be used in the principle shown.
