Definitions

  • the invention relates to a trailer, in particular a caravan, with an assistance system and an assistance system.
  • a trailer for transporting goods is known from EP 0 598993 A1.
  • the well-known trailer has a double axle and is suitable for heavy loads.
  • This trailer has the disadvantage that it cannot be maneuvered by one person, or only with difficulty, since the double axle causes considerable resistance to the trailer turning sideways.
  • the jockey wheel drive known from G 9406515 U1 has the disadvantage that it quickly reaches the limits of its capacity with higher loads and especially with a double-axle trailer.
  • the present invention is based on the object of specifying a trailer and an assistance system for a trailer which allow the trailer to be maneuvered in an improved manner when the trailer is not connected to a motor vehicle.
  • a trailer having the features of independent patent claim 1 and by an assistance system having the features of claim 9 .
  • Advantageous developments of the invention are specified in the dependent claims.
  • the object is achieved according to the invention by a trailer with a double axle, in particular a caravan, with a drawbar, at least one support wheel and at least one adjustable support device, the drawbar being able to be supported on the support wheel via the adjustable support device, with an adjustment device being provided which, for The distance between the drawbar and the support wheel is adjusted by means of the adjustable support device, with an assistance system having at least one electric motor being provided and with the electric motor of the assistance system actuating the adjustable support device at least indirectly to adjust the distance between the drawbar and the support wheel.
  • an assistance system for a trailer with a double axle in particular for a caravan, which trailer has a drawbar, at least one support wheel, at least one adjustable support device and an adjustment device, the drawbar being able to be supported on the support wheel via the adjustable support device , wherein the adjusting device serves to adjust a distance between the drawbar and the support wheel by means of the adjustable support device, wherein the assistance system has at least one electric motor and wherein the electric motor of the assistance system actuates the adjustable support device at least indirectly to adjust the distance between the drawbar and the support wheel.
  • the trailer with double axle and the drawbar are not part of the assistance system according to the invention.
  • the at least one support wheel, the at least one adjustable support device and the adjustment device are not necessarily components of the assistance system according to the invention.
  • the assistance system according to the invention can also be manufactured and sold independently of a trailer that has a support wheel, at least one adjustable support device and an adjustment device.
  • the assistance system has at least one sensor, which at least indirectly detects whether an axle of the double axle is at least essentially unloaded.
  • the lifting is stopped.
  • One or more people can then maneuver the trailer, which is only supported on the other axle and the jockey wheel, more easily. Especially no longer has to be overcome the high resistance that arises with two loaded axles, especially when turning the trailer.
  • the senor is designed as an inclination sensor, which at least indirectly detects an inclination of a plane determined by the axes of the double axis relative to a horizontal alignment. As a result, when a specific inclination is reached, it can be recognized that the axle is at least essentially unloaded.
  • the drawbar is at least essentially rigidly connected to a trailer frame of the trailer and that the sensor is designed as an inclination sensor that detects an inclination of the drawbar relative to a horizontal alignment. This simplifies the design of the assistance system, since the sensor can be arranged, for example, inside a housing for the electric motor.
  • the assistance system prefferably uses the inclination sensor to detect an initial inclination when the axle is still loaded, and for the assistance system to correct a current inclination detected using the inclination sensor by the initial inclination when it detects whether the axle of the double axle is at least essentially unloaded.
  • this enables a differential measurement, so that a measurement is also possible on an inclined subsoil (floor) or on a hillside.
  • the detected output slope can also be processed in other ways. For example, the release of an electric parking brake on the trailer can then be prevented for safety reasons.
  • the assistance system positions the support wheel relative to the adjustable support device according to a certain direction of movement of the drawbar when the assistance system determines that the axle of the double axle is at least essentially unloaded.
  • the desired shunting movement can then be carried out directly. This avoids tedious turning of the support wheel about an axis of the support device.
  • the certain direction of movement of the drawbar can be selected by a user.
  • the assistance system has a safety device, that the safety device records at least one motor current of the electric motor, that the safety device limits at least one output torque of the electric motor when a specific maximum value for the at least one motor current is reached, and that the maximum value for the at least a motor current is determined in such a way that overloading of components when the adjustable support device is actuated is prevented. In this way, forces on components, in particular on the adjustable support device (lifting support), can be limited and the components can thus be protected against overloading.
  • the electric motor of the assistance system actuates the adjustable support device by means of a preferably self-locking gear. As a result, the demands on the electric motor can be significantly reduced.

  • the trailer 1 and the assistance system 2 are shown only schematically and not true to scale.
  • the trailer 1 can stand, for example, on a level, horizontal and tarred floor 100 .
