Definitions

  • the invention relates to a trailer for leisure purposes, in particular a caravan.
  • the present invention is based on the object of specifying a trailer which is designed in an improved manner and in which a cooling system can be implemented in a particularly advantageous manner.
  • a trailer for leisure purposes in particular caravans, with a chassis, a shell carried by the chassis and a drawbar connected to the chassis, with at least one heat exchanger being provided, with the heat exchanger being mounted in a mounting area for the heat exchanger is and where the Mounting area for the heat exchanger composed of a lower area provided inside, beside and under the chassis and a front area provided in front of the shell.
  • At least one heat exchanger is arranged at least essentially directly above the drawbar. This allows the heat exchanger to be positioned as well as possible in the air flow (airstream). It is correspondingly advantageous that at least one heat exchanger is arranged directly on the drawbar and/or that the heat exchanger is connected to the drawbar.
  • At least one heat exchanger is arranged at least essentially directly in front of the shell. It is advantageous that at least one heat exchanger is arranged at least essentially under a window provided at the front of the shell. In these configurations, the heat exchanger can advantageously be arranged in the air flow. If the heat exchanger is dimensioned in such a way that it can or could be installed under a window, this also has the general advantage that there is a larger area of application, which reduces costs.
  • At least one heat exchanger is arranged upright.
  • the free height, in particular above the drawbar, at the front of the shell, which is not required for the window, can be used to place the heat exchanger in the air flow over as large an area as possible.
  • At least one heat exchanger is arranged in the lower area.
  • a visually inconspicuous location can be chosen for the heat exchanger.
  • at least one heat exchanger it is advantageous for at least one heat exchanger to be arranged horizontally.
  • At least one driven axle is provided, that an electric motor is provided which is used to drive the driven axle, that a cooling system is provided for the electric motor and that the cooling system comprises the at least one heat exchanger.
  • the electric motor can also be used for recuperation in order to partially convert kinetic energy back into electrical energy.
  • FIG. 1 shows a trailer, in particular a caravan, according to an exemplary embodiment of the invention in a partial, schematic representation.
  • FIG. 1 shows a trailer 1, in particular a caravan 1, according to an exemplary embodiment of the invention in a partial, schematic representation.
  • a vehicle in particular a hybrid or electric vehicle
  • it can be moved, for example, on a road 100 in a direction of travel 101 .
  • the trailer 1 comprises a chassis 2, a shell 3 arranged on the chassis 2 and at least one driven axle 4 which can be driven by an electric motor 5.
  • the trailer 1 also has a drawbar 6 , a support wheel 7 and an adjustable support device 8 .
  • the drawbar 6 is supported on the support wheel 7 via the adjustable support device 8 when the trailer is not attached to a vehicle. With the adjustable support device 8, the distance between the drawbar 6 and the support wheel 7 can be adjusted.
  • the trailer has at least one heat exchanger 9,10. In this case, only one of the heat exchangers 9, 10 can be provided.
  • the heat exchangers 9, 10 are mounted in a mounting area 11 for the heat exchangers 9, 10.
  • the mounting portion 11 is composed of a lower portion 12 which is provided inside, beside and under the chassis 2, and a front portion 13 which is provided in front of the shell 3 together.
  • the heat exchanger 10 is arranged directly above, in particular directly on, the drawbar 6 .
  • the heat exchanger 10 can be connected to the drawbar 6 .
  • the heat exchanger 10 can also be connected to the shell 3 in the front area 13 .
  • the heat exchanger 10 can in particular be arranged directly in front of the shell 3 .
  • the heat exchanger 10 is arranged upright in this embodiment. In this embodiment, the heat exchanger 10 is placed under a window 15 provided in the shell 3 at the front.
  • the position on the drawbar (drawbar) 6 is particularly well suited for mounting the heat exchanger 10 .
  • the center of gravity when the heat exchanger 10 is mounted on the drawbar 6 is then favorably influenced in terms of driving dynamics in comparison to an arrangement on the upper edge 17 .
  • the front area 13 is good in the wind. Furthermore, there is little need for integration in the front area 13 for integration into a cooling system 16.
  • the heat exchanger 9 is arranged in the lower area 12 .
  • the heat exchanger 9 is arranged horizontally.
  • the heat exchanger (radiator) 9 can be arranged under the vehicle floor, for example on the outside of a side member of the chassis 2 .
  • an efficient cooling system 16 for the electric motor 5 can be implemented, with the cooling system 16 comprising at least one of the heat exchangers 9, 10.
  • the outlay for piping can be kept low by positioning the heat exchangers in the assembly area 11 .
