  • the invention further relates to a rail vehicle with such a car body, a method for producing the car body and a method for producing the rail vehicle.
  • the operation of rail vehicles requires a variety of equipment, such as a voltage transformer, control devices for controlling other equipment, containers for liquids, pumps for liquids, brake system equipment and electrical distributors. These devices are placed above all on cars for high-speed trains at the bottom of the floor.
  • equipment such as a voltage transformer, control devices for controlling other equipment, containers for liquids, pumps for liquids, brake system equipment and electrical distributors.
  • These devices are placed above all on cars for high-speed trains at the bottom of the floor.
  • the floor construction has receptacles for fastening adapter elements on its underside.
  • the adapter elements are designed for fastening a profile frame.
  • the profile frame consists of frame segments, which are formed with means for fastening underfloor units and equipment. The devices are hung on the profile frame.
  • Underfloor (ie, below the bottom of the car body) arranged devices can be different in weight.
  • a voltage transformer may weigh several tons while an electric distributor weighs only a few kilograms.
  • the weight should be balanced, ie it should not, for example, all the particularly heavy equipment in the front of the car and all light equipment in the rear of the car be arranged.
  • the particularly heavy equipment should be located with its center of gravity in the middle of the car body and should be as possible, the center of gravity of the underfloor devices located in the middle of the car body. Since the devices but also have very different volumes and are to be connected, for example, to cables or liquid lines, the mounting location for the individual devices can not be chosen freely.
  • At least one particular local area for housing a particular device must be respected, or additional leads must be provided or cables are accepted.
  • the production of connections of the equipment immediately below the bottom of the car body is difficult.
  • the assembly can be facilitated by the fact that the devices are first attached and connected in the underfloor area and only then other facilities and parts of the car are mounted.
  • the effort for loosening and restoring the connections and disassembly of the devices is difficult.
  • even the arrangement of particularly heavy equipment below the ground contributes to the fact that the overall center of gravity of the car is above the rails. With a bracket on the underside of the floor, which allows a lower arrangement of heavy equipment, the center of gravity can be lowered. However, such a stable additional bracket increases the overall weight of the car.
