Definitions

  • Drive train unit with electrical machine and internal combustion engine; and a method for operating a drive train unit
  • the invention relates to a hybridized drive train unit with an electric machine (drive machine) and an internal combustion engine, the drive train unit being designed for use in a motor vehicle, such as a car, truck, bus or other commercial vehicle.
  • the invention also relates to a method for operating this drive train unit.
  • a hybrid / hybridized drive train unit for a motor vehicle with a first sub-unit having an electrical machine and a second sub-unit having an internal combustion engine and a second sub-unit downstream of the internal combustion engine, the two sub-units on the output side / with their outputs via a common planetary gear , whose / of which planetary gear a ring gear is connected to at least one gear output of the powershift transmission, are coupled to an output.
  • this structure enables the two sub-units to be coupled to the output as directly as possible.
  • the internal combustion engine can be switched off in a simple manner, namely by holding the ring gear of the load shift transmission, which means that a purely electric drive can be selected as simply and directly as possible. Further advantageous designs are claimed with the subclaims and explained in more detail below.
  • a rotor shaft of the electrical machine is (preferably permanently) non-rotatably connected to a sun gear of the planetary gear and / or a planet carrier of the planetary gear is connected to the output ( preferably permanently) is connected.
  • a (first) brake preferably implemented as a claw brake, acts on the ring gear of the planetary gear, which holds the ring gear in its activated position relative to the gear housing of the powershift transmission, a simply constructed switching device is used to switch between a purely electric drive mode and a hybrid propulsion mode.
  • the load shift transmission has a Ravigneaux set or this Ravigneaux set directly bil det.
  • a ring gear of the powershift transmission is connected to the ring gear of the planetary gear. This results in a skilful direct coupling of the powershift transmission with the planetary gear.
  • an output shaft of the internal combustion engine has a first clutch (preferably designed as a dog clutch) with a first sun gear of the powershift transmission, a second clutch (preferably realized as a friction clutch) with a planetary carrier of the powershift transmission and / or a third clutch (preferably also realized as a friction clutch) can be connected to a second sun gear of the powershift transmission.
  • a first clutch preferably designed as a dog clutch
  • a second clutch preferably realized as a friction clutch
  • a third clutch preferably also realized as a friction clutch
  • a (second) brake (preferably implemented as a friction brake) is operatively connected to the first sun gear of the powershift transmission. This facilitates the controllability of the powershift transmission.
  • a (third) brake (preferably implemented as a friction brake before) is operatively connected to the planetary carrier of the powershift transmission. This makes it even easier to control the powershift transmission.
  • the invention relates to a method for operating a drive train unit according to the invention according to at least one of the above-described embodiments, wherein in a hybrid drive mode (preferably by opening / deactivating the first brake) the internal combustion engine via the powershift transmission, the ring gear of the planetary gear, in addition to a drive power transferred from the electric machine to the planetary gear, and in a purely electric drive mode (preferably by engaging / activating the first brake) only the electric machine transmits drive power to the planetary gearbox, while the gearbox output of the powershift gearbox is supported by the gearbox housing / is held.
  • a hybrid drive mode preferably by opening / deactivating the first brake
  • the internal combustion engine via the powershift transmission
  • the ring gear of the planetary gear in addition to a drive power transferred from the electric machine to the planetary gear
  • a purely electric drive mode preferably by engaging / activating the first brake
  • the internal combustion engine which is decoupled from the powershift transmission, is switched on first, and then, by means of a targeted slip operation, a (preferably previously in an open position) friction clutch (preferably the second or third clutch of the Ravigneaux set) a certain torque is built up in a claw brake holding the transmission output, then the claw brake is released / opened / deactivated and, in turn, a speed adjustment between the output shaft of the internal combustion engine and the transmission output takes place, whereupon the friction clutch is completely closed.
  • a friction clutch preferably the second or third clutch of the Ravigneaux set
  • the speed adjustment between the output shaft of the internal combustion engine and the transmission output takes place by adjusting the speed (the rotor shaft) of the electrical machine (preferably by setting a negative one Speed / by a generator operation), the switching process is carried out with as few resources as possible.

If recuperation is to take place in hybrid mode (recovery of kinetic energy from the vehicle), the small drag torque of the internal combustion engine 4 can be effectively increased by targeted tensioning in the powershift transmission 5. As a result, higher electric motor torques in the moment equilibrium on the coupling planetary set 7 are also possible. However, it is better to switch to E-mode, since no kinetic energy is used here to “heat” friction elements, but rather more energy can actually be recuperated in the electric motor 2.
