Definitions

  • the invention relates to a central electrical device for operating an electric drive and/or recuperation axle of a trailer or semi-trailer of a commercial vehicle.
  • the electric drive and/or recuperation axle is preferably designed as an e-drive axle.
  • the trailer or semi-trailer can be designed as a tipper, central axle trailer or semi-trailer.
  • e-Drive axles are used in trailers or semi-trailers of commercial vehicles and are characterized by the fact that an electric drive machine is integrated into the axle.
  • Such a trailer or semi-trailer can be attached to any truck or tractor and turns it into a hybrid vehicle.
  • the additional self-propulsion of the trailer or semi-trailer influences the traction and acceleration of the entire vehicle.
  • All known electric trailer systems use various component arrangements which contain the electrical and/or electronic components necessary for power supply and drive. These component arrangements are distributed throughout the entire trailer or semi-trailer and make installation at only one manufacturing location of the trailer or semi-trailer or on a regular production line difficult.
  • the central electrical device then comprises an electric drive and/or recuperation axle of a trailer or semi-trailer a commercial vehicle with at least two electrical and/or electronic components, which are arranged in a common housing and are connected within the housing in such a way that the components that operate at the same voltage level are connected to a common interface formed on the housing for connection to the electrical Drive and/or recuperation axle of the trailer or semi-trailer of the commercial vehicle are guided.
  • Such a central electrical device has a reduced number of interfaces that connect the central electrical device to the trailer or semi-trailer and can be delivered pre-assembled to the manufacturer of the trailer or semi-trailer.
  • the manufacturer of the trailer or semi-trailer can dispense with subsequent manual completion for assembly, as only the few interfaces need to be connected to the trailer or semi-trailer. This shortens assembly time and saves assembly steps. It is also possible to largely dispense with the use of trained production personnel and highly specialized employees who, for example, have knowledge of high-voltage components and circuits. No design changes to the trailer or semi-trailer are necessary.
  • the central electrical device can be produced in large quantities.
  • the manufacturer of the trailer or semi-trailer only has to replace a conventional axle with an e-Drive axle.
  • the e-Drive axle is an axle driven by an electric motor, with the electric motor positioned on the axle. This makes it possible to create an electric trailer functionality that includes the recovery of kinetic energy from mechanical energy, which is referred to as recuperation, as well as the provision of a driving force from electrical energy to support the tractor in overcoming driving resistance, which is referred to as traction.
  • the housing 6 contains a cooling system 22 for the electric drive and/or recuperation axle 16.
  • This cooling system 22 is connected to a housing-internal cooling line 23, which is connected to a cooling interface 24 formed on the housing 6, for example in the form of a coupling. leads.
  • the cooling system 22 is connected to the high-voltage battery 9 and other internal components for cooling them via a second housing-internal cooling line 25.
  • the cooling system 22 is controlled by the low-voltage module 38, which controls the cooling system 22 depending on signals from the control device 20 attached to the mechanical axis 17.
  • Corresponding connections 29, 30, 31 run from the chassis to the electric drive and/or recuperation axle 16, which is shown in simplified form in FIG. 2 for the sake of clarity. These lines 29, 30, 31 can be advantageously laid within the framework of the trailer 2.

  • the battery charger 12 can be connected via a further interface 34 to an external local network 35 for charging the high-voltage battery 9.
  • the trailer 2 has its own brake control unit 36, which is connected to the ABS and ESP system of the tractor 4 via a line 41 with a standardized plug 40, for example ISO 7638.
  • the brake control unit 36 of the trailer 2 receives all information about the driving and braking behavior of the tractor 4.
  • the external coupling of the brake control unit 36 to the low-voltage module 38, which takes place via a control unit interface 43 of the housing 6, enables data and energy exchange Both directions via the line 44 between the brake control unit 36 and the control unit 20 of the electric drive and/or recuperation axle 16 are possible via the existing low-voltage interface 15.
