Definitions

  • the invention relates to a transition bellows for a car transition between two cars of a vehicle, wherein the transition bellows is divided into at least two bellows sections in the longitudinal direction and the bellows sections are connected to one another by connecting means.
  • baffles i. H. Exposed surfaces in the direction of travel, in the outer contour of the rail vehicle, should be avoided as far as possible. There is a particular risk of impact surfaces on the outer contours of the rail vehicle in the area of the wagon transition.
  • transition devices In order to improve the aerodynamic properties of a rail vehicle train, transition devices, especially in high-speed traffic, are increasingly being designed in such a way that their outer contour runs as flush as possible with the outer contour of the train.
  • the mounting frames and transition bellows used are subject to manufacturing tolerances.
  • the manufacturing tolerances In order to prevent outwardly protruding impact surfaces from occurring, it is known to minimize the manufacturing tolerances, in particular to design the manufacturing tolerances in such a way that the bellows does not protrude beyond the car bodies. Therefore, the manufacturing tolerances designed with sufficient safety inwards, so that there is often an inward offset, which is less disadvantageous in terms of flow than an outward offset.
  • the invention is based on the object of proposing a car transition area of a multi-part vehicle that is streamlined and at the same time easy and quick to replace.
  • a transition bellows according to the invention for a car transition between two cars of an at least two-part or multi-part vehicle is divided in the longitudinal direction into at least two bellows sections and the bellows sections are connected to one another by connecting means, the connecting means each comprising at least one guide element and at least one fixing element complementary to the guide element. which are suitably designed to allow a linear movement of the locking element to the guide element during assembly of the transition bellows and to fix the locking element to the guide element and thus to connect the at least two bellows sections.
  • the at least two bellows sections of the transition bellows can thus be connected to one another in an adjustable manner by means of a linearly movable locking element that can be fixed on the guide element.
  • the transition bellows has at least two strips of material which are held together by a bellows frame, the bellows frame being divided into at least two bellows frame sections and the bellows frame sections being connected to one another by the connecting means.
  • the connecting means can be correspondingly connected to the bellows frame sections, so that when the transition bellows is installed, a linear movement of the locking element relative to the guide element is permitted and the locking element can be fixed to the guide element and the bellows frame sections can be connected in this way.
  • the guiding element can be attached to one bellows frame section and the locking element is attached to the other bellows frame section.
  • a bellows frame runs at least partially around the car transition. It spans a plane that is in particular perpendicular to the longitudinal axis of the car transition.
  • a bellows frame In order to form the fold or wave shape of the transition bellows, at least two strips of material are held together by a bellows frame, for example clamped.
  • the bellows frame can be designed in the form of a profile as a connecting or clamping profile.
  • a groove-shaped profile can hold the fabric strips together by clamping, or it can be designed as a C or U profile.
  • the strips of fabric held together can be two separate panels of fabric, or one panel of fabric is held folded in the bladder frame.
  • the fabric strips extending out of a bellows frame create the fold or wave shape of the transition bellows.
  • the transition bellows has a plurality of bellows frames. Bellows frames as such are known from the prior art.
  • the mounting frames are also divided in the longitudinal direction of the bellows, at least into two resulting mounting frame sections.
  • the respective mounting frame sections of a mounting frame are connected to one end of the car.
  • the bellows frame can be divided at least into a lower and an upper bellows frame section, with the connecting means connecting the bellows frame sections to one another.
  • the upper half of the side wall and the lower half of the side wall can thus be connected to one another in an adjustable manner by means of the locking element, which can be moved linearly in the guide element and fixed on the guide element.
  • the transition bellows can be divided at least into a lower transition bellows half comprising the at least one lower side wall half and an upper transition bellows half comprising at least one upper side wall half.
  • the vertical displaceability of the side wall halves to one another and the subsequent fixing of the side wall halves to one another enables tolerance compensation in the Z direction parallel to a vertical axis of the transition bellows or the vehicle during assembly.
  • the X-direction runs parallel to the longitudinal axis of the transition bellows or the vehicle, ie in the direction of passage of the car transition between the two cars of the vehicle.
  • the Y-axis is horizontal and coplanar with the longitudinal axis, but transverse to the longitudinal axis.
  • a bottom of the bellows can be divided longitudinally into at least one right and left bottom section and a roof of the bellows can be divided longitudinally into at least one right and left roof section, with the guide element being arranged in a suitable manner, when the transition bellows is assembled, a linear movement of the To allow locking element in the horizontal direction.
  • the bellows frame can then in turn be divided at least into a right and a left bellows frame.
  • the transition bellows can be divided at least into a right half of the transition bellows comprising the at least one right floor half and the right half of the roof and into a left half of the transition bellows comprising the at least one left half of the floor and the left half of the roof.
  • Both the respective floor halves can be connected to one another with the connecting means and the respective roof halves can be connected with the connecting means.
  • the drilling templates for the attachment frame sections are made separately in the front wall of the car body so that the corresponding bellows sections, in this example an upper and lower half of the bellows, are attached to the Aerodynamically optimized top and bottom edges of the car body can be aligned.
  • Tolerance compensation here in the example along the vertical axis of the transition bellows, can take place during assembly of the transition bellows.
  • the drilling templates for the right and left mounting frame sections can be made separately and aligned with the outer contour of the vehicle in the end wall of the car body. A tolerance compensation can then take place in the transverse direction.
  • the arrangement of the bellows sections aligned with the outer contour of the vehicle can result in gaps between the bellows sections in the area of the respective division.
  • a further development consists in the mounting frame sections being designed as mutually complementary frame profiles in the area of the division and being arranged in an overlapping manner in the area of the division. For example, if they have a C-profile in cross section, one mounting frame section can be guided in the other and moved accordingly, so that a sliding fit is also formed.
  • the bellows sections in particular the material strips of the bellows sections, are arranged at least partially overlapping, in particular perpendicular to the longitudinal direction of the bellows.
  • the bellows sections, in particular the fabric strips of the bellows sections, thus overlap at least partially in the region of the division of the transition bellows into the bellows sections.
  • An advantage of the invention is that the transition bellows according to the invention can be exchanged without a complicated separation of the carriages of the vehicle.
  • the transition bellows that is flush with the outside contour is designed with at least one separation point in the longitudinal direction of the transition bellows. In this way, the transition bellows can be divided, for example, into an upper and lower part and/or a right and left side part, which can be exchanged individually and without costly cable separation.
  • the adjustable connecting elements described are provided to compensate for the body shell tolerances that occur, in order to allow tolerance compensation in the Y and/or Z direction.
  • the guide element is designed accordingly as a slot or as a guide rail or as a sliding seat for the locking element.
  • the connecting means can each have at least two holding means for holding the at least two bellows sections, in particular the respective bellows frame sections, with one holding means comprising the guide element and the other holding means comprising the fixing element complementary to the guide element.
