Definitions

  • the invention relates to a caravan according to the preamble of claim 1
  • a caravan or caravan is a trailer for a motor vehicle, in which a suitable device for the living and staying of people is installed.
  • Such a caravan is traditionally pulled by the towing vehicle in road traffic as a trailer without any own drive.
  • it is a single-axle trailer or a trailer with one
  • Hybrid vehicles are increasingly being used as motor vehicles, the drive of which consists of a combination of an internal combustion engine with an electric drive.
  • the electric drive can be used in such a way that it acts in addition to the internal combustion engine and is switched on when increased power is required in acceleration phases or when driving up a slope.
  • the electric drive draws its energy from an electrical energy store, in particular a battery, which is charged during a smooth ferry operation or during regenerative braking.
  • Electric vehicle a noticeable reduction in range and this can lead to the fact that the required additional power of the electric drive is not available for long enough in hybrid vehicles because the battery is exhausted.
  • caravans Due to their high construction, caravans naturally have a large air resistance and therefore cause a noticeably higher fuel or
  • trailers It is known in the prior art for other trailers to equip them with a battery or energy supply unit for generating electricity in order to supply the pulling vehicle with energy or to contribute to propulsion via driven wheels of the trailer.
  • a battery or energy supply unit for generating electricity in order to supply the pulling vehicle with energy or to contribute to propulsion via driven wheels of the trailer.
  • trailers are also referred to as range extenders to increase the range.
  • range extenders to increase the range.
  • trailers can significantly increase the range of long-distance electric vehicles.
  • Hybrid vehicle known in which an internal combustion engine with a generator generates electricity on the energy trailer. From DE 44 1 1 844 A1 a trailer with batteries is known, which are arranged above the trailer axle, as well as from EP 0 040 1 1 1 A1.
  • batteries are known for devices and devices in the home or for shunting drives with which a caravan can be moved into its position, for example on a campsite.
  • the size and capacity of these batteries is therefore not suitable for a driver drive during the
  • Modern batteries can be used as batteries for such trailers, which can be referred to as high-performance batteries and which have a higher energy density in relation to lead batteries in terms of weight and / or volume. This is above and outside the corresponding values of the lead batteries.
  • these are, for example, nickel-hydrogen, nickel-iron, nickel-zinc, nickel-metal hydride and silver-zinc as well as sodium-nickel chloride and sodium-sulfur batteries.
  • Lithium ion batteries are the most widely used. With regard to a caravan, it is important for such batteries to arrange them cheaply. An increase in the construction height should be avoided. Furthermore, it is desirable that the arrangement is advantageous in terms of the distribution of the center of gravity, since it is a single-axle trailer whose drawbar load on the
  • the present invention has for its object to provide a caravan with batteries to increase the range when pulling the caravan, in particular with hybrid or electric vehicles, with which the aforementioned disadvantages are avoided and which is advantageous and safe
  • the object is achieved in that in a caravan with a battery and an axle or a tandem axle, the battery for
  • the floor of the caravan corresponds to the interior floor on which the people walk.
  • the overall result is a very flat and low body, which does not require any additional body height compared to a conventional caravan and therefore does not increase the air resistance.
  • the battery is designed to provide electricity for an additional drive. If, for example, a conventional starter battery of a motor vehicle with an internal combustion engine has a maximum capacity of approximately 100 Ah and can thus theoretically store an energy of approximately 1.2 kWh at 12 V, the method shows Battery of the caravan according to the invention has a significantly higher energy density. This can be values of more than 50 kWh, for example. Using a suitable cable connection, this electricity can be used by a pulling electric vehicle
  • the focus of the caravan chassis is lower and there is an improvement in the dynamic driving behavior of the trailer.
  • the low center of gravity advantageously reduces the dynamic vertical load shift when accelerating and especially when braking.
  • the overall center of gravity of the caravan is even lower compared to a conventional one, since without the battery the overall center of gravity is relatively high.
  • the battery is flat and has a height approximately at the height of the chassis frame or
  • the battery can be an accumulator.
  • other electrical energy stores such as, for example, double-layer capacitors.
  • the battery is divided into a front battery and a rear battery, the axle or tandem axle being arranged between them.
  • a division into more than two partial batteries is also conceivable.
  • the result is smaller units that are easier to handle in production.
  • At least one cross member and / or at least one axle element can be arranged between the front battery and the rear battery.
  • Axle suspension elements that extend across the entire width of the caravan, such as a torsion tube
  • the front battery and the rear battery are advantageously positioned with respect to a pivot point of the caravan about its axis in such a way that there is a desired vertical load or a symmetrical weight distribution around the pivot point.
  • the center of gravity of the partial battery can be determined by the position and thus the lever arm relative to the contact point of the wheels of the caravan with a neutral or a desired load torque. This makes it possible to build specific
  • ballast such as weights, filled water tanks etc. It is conceivable that in the production of the caravan, depending on the structure and other circumstances, one or both batteries are mounted in a specific one of several possible positions. By avoiding ballast weights, unnecessary weight can be avoided and the permissible payload can be maximized.
  • the vehicle frame can consist of outer longitudinal beams running in the longitudinal direction of the vehicle and an inner frame made of in
  • the inner frame can consist of parallel standard profiles, in particular open profiles.
  • This parallel arrangement of the inner beams offers the possibility of providing standardized frames.
  • the battery or the sub-batteries can be variably inserted and screwed into this. In particular, this can also be used to react to the load distribution of the body of the caravan and to adapt the production for different models. The result is a larger one
  • the inner beams are advantageously connected at their front and rear ends to cross beams which are arranged between the outer longitudinal beams.
  • the inner beams and the inner frame have a reinforcing effect and the outer longitudinal beams of the vehicle frame can be designed more easily.
  • the floor of the caravan on which people walk and run can also be laid out more easily, since there are only shorter unsupported lengths.
  • One or more cross members can be arranged in front of and / or behind the battery or battery parts.
  • a suspension of the battery can be achieved by providing a cross member on the front and rear of each sub-battery. In this alternative embodiment, no inner support is required and the battery is held and mounted on the cross supports alone.
  • the battery can be a high-performance battery, in particular a lithium-ion accumulator.
  • the wheels of the caravan can have electric drive motors which can be supplied with electricity from the battery.
  • FIG. 1 shows a vehicle frame 1 of a caravan according to the invention with the wheels 2 and a coupling head 3 and a support wheel 4.

Due to the exact position with respect to the axis 13 of the front battery 10 and the rear battery 1 1, for example, a drawbar load on the coupling head 3 can be determined when the caravan is not loaded.
