    description
    Fastening device for a device carrier on a car body of a rail vehicle.
    Technical area
    The invention relates to a fastening device for a device carrier to a car body of a rail vehicle.
    State of the art
    Under the car body of a rail vehicle many of the necessary for the operation of the rail vehicle equipment (underfloor equipment) are attached. Typically, so-called traction containers, auxiliary converters, compressed air modules, braking resistors, battery modules,
    Air conditioners or similar mounted. In car bodies made of light metal, the attachment of these devices can be done on so-called C-rails, in which holders are inserted and fixed. These C-rails can be made very simple and inexpensive as part of an extruded light metal profile, there are no additional components required.
    Commonly also directly to the car body welded brackets to which the equipment carrier are fastened directly by means of screw. Modern rail vehicles, especially suburban trains (subways) are often constructed of light metal, but the underfloor devices and other attachments are usually installed in steel containers. At the joints between the containers and the car body thus very large mechanical stresses can occur due to the different thermal expansions of the adjacent components. These stresses can even lead to loosening or loosening of the joint. Alternative types of attachment (for example silent blocks with rubber support) can usually not be used for reasons of cost and space. The space under the car body should usually be used as optimally as possible, so that the attachment of the underfloor installations should cause as little loss of possible height of the underfloor installations. From the prior art elastic connecting pieces made of sheet steel are known, which can accommodate the different thermal expansions. However, the use of these components requires the provision of consoles on the car body, mounting on C-rails is not possible. Likewise, the use of these connectors reduces the possible height of the equipment carrier and the installation is expensive, since the equipment carrier must be lifted during assembly over its horizontal end position to mount the connectors can.
    Presentation of the invention
    The invention is therefore based on the object to provide a fastening device for equipment carrier on the underside of rail vehicle car bodies, which the different thermal expansions of
    Light metal car bodies and steel equipment carriers can accommodate, are easy to assemble and can be mounted on common C-rails.
    The object is achieved by a fastening device for a device carrier on a car body of a rail vehicle with the features of claim 1. Advantageous embodiments are the subject of the subordinate claims.
    According to the basic idea of the invention, an attachment device for a device carrier or an underfloor device on a vehicle body of a rail vehicle is described, in which the vehicle body is provided on its underside with C-grooves, and wherein the equipment carrier with at least one elastic connecting part on a C Groove of the car body is detachably connected, and wherein the elastic connecting part has two bores for producing a screw connection to a respective sliding block and a bore for producing a screw connection with a device carrier, and wherein the elastic connecting part is made of bent sheet steel and two mutually opposite directions S- comprises shaped portions which each extend between a bore for producing a screw connection to a sliding block and the bore for producing a screw connection with a device carrier.
    As a result, the advantage can be achieved to produce an elastic connection of a car body with a device carrier, which can optimally use the space in the vertical direction and is well suited for the connection of light metal car bodies with equipment carriers made of steel.
    In particular, it is advantageous that the
    Fastening device upon deflection of the car body (for example, by the passenger load) excessive and changing constraining forces prevented at the attachment points, which can otherwise lead to loosening the fasteners. Due to the direct attachment of the equipment carrier to the car body of the rail vehicle and the otherwise required intermediate cross member can be omitted, which are used for decoupling the equipment carrier of the car body.
    According to the invention, an elastic connecting part is provided, which is arranged between the car body and the equipment carrier. In this case, each individual connection point is to be arranged an elastic connection part. Typically, equipment carriers are connected to the carbody at four or more joints. The elastic connecting part is made of sheet steel and bent into an omega shape. At the two ends of the elastic connecting part in each case a bore for producing a screw connection to the car body is provided, in the middle of the elastic connecting part a bore for producing a screw connection with a device carrier is provided. The car body is provided on its underside according to the invention with C-grooves, in which sliding blocks are arranged slidably. This sliding blocks are designed screwed with the elastic connecting part.
    The shape of the elastic connecting part, in particular its omega shape, ensures a high load capacity with simultaneous elasticity along and across the car body and a low resistance to twisting. The equipment carriers can be decoupled from vibrations and torsions of the car body efficiently.
    The elastic connection part defines by its shape and the properties of its material, the elastic properties of the joint. For precise tuning of the vibration characteristics, in particular the natural frequency, recesses may be provided in the elastic connecting part. If these recesses are arranged in a bent section of the elastic connecting part, then a particularly effective influencing of the spring constant is possible.
    In a further development of the invention, it is recommended to remove between the attachment points of an elastic connecting part to a car body, the C-groove and possibly other parts of the carbody floor. As a result, the advantage can be achieved to be able to arrange equipment carrier with greater height below the car body. In practical embodiments of the invention, the C-grooves can be removed by milling.
    As a result, elastic connecting parts can be used, the largest vertical extension protrudes in the installed state on the mounting plane of the C-grooves upwards. In this way, the mounting plane for the device carrier can be offset upwards while retaining the elastic properties of the elastic connecting part. This allows the use of larger equipment carrier or a maximum distance of the equipment carrier of the track bed.
    Since in this case the connection points between the elastic connecting part and the device carrier are usually accessible only from below, an anti-rotation device is required in order to be able to produce the corresponding screw connection. It is recommended to use one for this connection
    Lead screw in a sleeve, with a positive connection between the sleeve and the screw is given. Furthermore, the sleeve against the elastic connecting part to secure against rotation, it is recommended to ensure a positive engagement of said components. In particular, it is advisable to equip the elastic connecting part with a non-circular recess (hole) and equip the sleeve with a corresponding shape, which can engage in this recess.
    In a further development of the invention, it is advisable to equip the joints of the elastic connecting part with the car body with a Schaub connection, in which the pressing force of the screw is introduced in each case by means of a force distribution plate in the elastic connecting part. This force distribution plate is especially designed compared to conventional washers. The force distribution plate is substantially cuboid with a bore for the passage of a screw, said bore being arranged asymmetrically in the installed position of the force distribution plate. It is essential to offset the position of the bore towards the center of the elastic connecting part, since such a loosening of the screw connection can be prevented even under load of the elastic connecting part by the weight and inertia forces of a device carrier. The weight forces of a device carrier cause a torque in the
    Attachment point to the car body, whereby the screws for the sliding blocks are subjected to tensile forces. The asymmetry of the position of the bore for this screw causes the connection part to always remain in contact with the C-rail and no parting line (gaping) is created.
    Furthermore, it is advantageous to equip the force distribution plate with a rotation, in particular a positive rotation by means of a molding on the force distribution plate, which engages in a recess of the elastic connection part is advantageous. This ensures that the force distribution plate is securely installed in the intended position of use and can not twist even when tightening the screw, which would severely limit the function of the force distribution plate.
