Definitions

  • Gear unit with two planetary gear sets and a one-piece planetary gear carrier and a motor vehicle with such a gear unit
  • the invention relates to a transmission unit for a hybrid motor vehicle to spend torque between on the one hand an internal combustion engine and / or an electrical machine and on the other hand a transmission output or between the internal combustion engine and the electrical machine, comprising a planetary gear with a first and a second planetary gear set , wherein the two planetary gear sets comprise a common first planetary gear carrier and wherein the first planetary gear set has a direct coupling with the electric machine and the transmission output of the transmission unit and comprises at least two different single planetary gear sets that mesh with each other during operation.
  • P2 parallel hybrids are known that work with an electrical machine located between the internal combustion engine and the transmission, with a separating clutch serving to disconnect the internal combustion engine from the drive train separate. In this case, it can be operated in pure electric mode, with the electric machine delivering the torque to the gearbox and not to the internal combustion engine.
  • the advantage of this flybridge variant is that it is possible to use an existing transmission with an electric motor and a separating clutch to separate the combustion engine from the drive train.
  • serial, serial-parallel or power-split hybrids are known from the prior art, in which a generator driven by the internal combustion engine generates electricity which is used to drive an electric motor drives the vehicle (series operation). These transmissions are also called power split transmissions. In most arrangements, however, part of the power of the internal combustion engine is transferred mechanically to the wheels (series parallel operation).
  • DE 102016221 045 A1 is known from the prior art, which relates to a gear arrangement for a hybrid vehicle in which a connection for an internal combustion engine, a connection for an electrical machine and a gear part of the gear arrangement are arranged to be coupled to one another.
  • the transmission part includes a simple Ravigneaux planetary gear set with two planetary gears ben and a single ring gear.
  • the transmission part also has two brakes and two clutches as frictional shifting elements.
  • the publication also discloses a drive arrangement with such a transmission arrangement and in each case an internal combustion engine connected to it and an electrical machine connected to it.
  • Also part of DE 102016221 045 A1 is a method for operating such a drive arrangement and a hybrid vehicle equipped with such a drive arrangement.
  • DE 102016221 045 A1 seems to disclose a concept with two planetary gear sets and four clutch devices to enable up to four forward gears for the internal combustion engine, two gears for the electric motor, one gear of the electrically continuously variable transmission (EVT, Electrically Variable Transmission) and to map a mode for stand charging.
  • EDT Electrically Continuous variable Transmission
  • EP 2 146855 B1 is known from the prior art, which describes a hybrid drive system for a vehicle, comprising a torsional vibration damper arrangement with a primary side to be coupled to a drive shaft of a drive unit for joint rotation about an axis of rotation and with a damper element arrangement via a damper element arrangement secondary side supported with respect to the primary side for torque transmission and rotatable about the axis of rotation with respect to the primary side, a clutch arrangement with an input area which is coupled or to be coupled to the secondary side for common rotation about the axis of rotation (A), and with a frictional engagement with the Input area for rotation couplable output area, an electric machine, with a stator arrangement the electric machine is carried or to be carried on a stationary assembly and a rotor arrangement of the electric machine is coupled to the output area of the coupling arrangement for common rotation about the axis of rotation, the input area of the coupling arrangement with the secondary side of the torsional vibration damper arrangement via a Hirth serration and / or
  • a torque transmission device comprising: an input shaft, a first planetary gear set which, as first gear elements, has at least one first planet gear for meshing with a first sun gear and with a first ring gear of the first planet gear set and a planet carrier for rotatably supporting we have at least one of the first planetary gears, a second planetary gear set, which as second gear elements at least one second planetary gear for meshing with a second sun gear and with a second ring gear of the second planetary gear set and for meshing with one of the first planetary gears, wherein at least one of the second planetary gears is rotatably supported by the plane carrier, a first braking device designed for releasably securing the second sun gear, and a second braking device designed for releasably securing at least one of the first transmission elements, a first separating clutch, designed for rotary connection of the input shaft with at least one of the first transmission elements, and a
  • DE 10 2018 130498 A1 which fenbart a gear unit for a hybrid motor vehicle, with a planetary gear, the planetary gear with a first planetary gear set and a second planetary gear set is equipped, an electrical machine coupled to a component of the planetary gear and several switching devices, each with a brake or a clutch and adjustable between an activated position and a deactivated position, the switching devices for switching different gear ratios between an input that can be coupled to an internal combustion engine and an output and / or between the electrical machine and the output are used, with no more than four switching devices for converting at least two different gear ratios in a drive state of the internal combustion engine, at least one gear ratio in a drive state of the electric machine and at least a gear ratio in a recuperation state of the electrical machine due to their activated and deactivated positions.
  • the disadvantages are therefore, inter alia, the additional weight and the costs that arise from the use of two electric machines, while only one is actually used to drive the vehicle. If, for example, a 60 kW electric motor is required to drive the vehicle in series operation, a 60 kW generator is also required. So twice the drive power has to be taken on board.
  • the known concepts are also disadvantageous because the electric motor each Weil requires an additional translation so that the two electrical gears can be adapted to the high speeds. This additional gear ratio leads to a loss of efficiency when driving purely on electric power. It is the object of the present invention to provide a more compact, more efficient, simpler to manufacture and especially space-optimized transmission unit in the radial direction.
