Definitions

  • the invention relates to a drive train according to the preamble
  • a drive rod for a motor vehicle with hybrid drive in each of which a clutch is arranged between an electric machine and an internal combustion engine or a transmission unit.
  • a clutch is arranged between an electric machine and an internal combustion engine or a transmission unit.
  • the torque generated by the engine and the electric machine transmitted through the gear unit to the drive wheels. If the electric machine can no longer produce a desired torque due to an excessively low state of charge of its energy source, then, in order to nevertheless obtain the desired torque at the drive wheels, the transmission unit ratio is changed accordingly.
  • a maximum torque is thus the sum of the moments of the internal combustion engine and the electric machine, taking into account the translation of the gear unit available.
  • the object of the invention is to propose an alternative drive train, which is characterized by high efficiency and / or high comfort.
  • the drive train connected in series in series comprises the following elements: an internal combustion engine, a hydrodynamic converter, a switchable clutch, an electric machine and an automatic transmission.
  • the drive train according to the invention makes it possible to increase the starting torque, in particular for heavy-load driving or continuous creeping operation under load.
  • the shiftable clutch can be closed even with a less accurate synchronization of the speeds drive and output side of the shiftable clutch, since the hydrodynamic converter compensates for the differences in speed. As a result, a faster connection of the internal combustion engine is possible.
  • Fig. 1 is a schematic representation of an embodiment of a drive train according to the invention.
  • Fig. 2 shows a time course of the rotational speeds of an electric machine and an internal combustion engine during a starting process.
  • FIG. 1 The exemplary embodiment of a drive train according to the invention shown in FIG. 1 shows the following elements connected in series in series: an internal combustion engine 1, a hydrodynamic converter 2, a shiftable clutch 3, an electric machine 4 and an automatic transmission 5.
  • the internal combustion engine 1 is connected via a shaft ⁇ a on the drive side with the hydrodynamic converter 2 frictionally.
  • the hydrodynamic converter 2 is connected via a shaft ⁇ b directly to the drive side of the shiftable clutch 3.
  • the shiftable clutch 3 in turn is connected on the output side via a shaft 6 c directly to the transmission input of the automatic transmission 5.
  • the hydrodynamic converter 2 is assigned a lock-up clutch 2a.
  • lock-up clutch 2a On the drive side in front of the converter 2 with lock-up clutch 2a arranged a torsion damper.
  • the electric machine 4 has a stator 4a and a rotor 4b, wherein the rotor 4b is non-positively connected to the shaft 6c, so that the electric machine 4 can transmit a torque to the shaft 6c during motor operation or a moment from the shaft 6c can record when the electric machine 4 is operated as a generator.
  • An embodiment of the electric machine 4 as an external rotor is also possible.
  • the internal combustion engine 1 is assigned a starter 7.
  • the internal combustion engine 1 can be designed for example as a diesel or gasoline engine.
  • the internal combustion engine 1 may also be a direct-starting internal combustion engine.
  • a direct-starting internal combustion engine for example an engine with gasoline direct injection, is characterized by the fact that it starts alone by means of deliberately used injection and ignition and therefore does not require any support for a starter or another electric machine for starting. In this case, can be dispensed with a starter 7.
  • the electric machine 4 is electrically, represented by the dashed line, with a corresponding power electronics and a power source 8, for example, a high-voltage battery connected.
  • the drive train is separated such that the hydrodynamic converter 2 and the internal combustion engine 1 are not connected to the output on one side of the clutch.
  • the electric machine 4 and the automatic transmission 5 on the other side are thus alone connected to the output.
  • the switchable clutch 3 is open in particular during a vehicle standstill before a startup. The approach from standstill then takes place purely electrically by the moment of the electric machine. 4 Such a starting operation or the rotational speed n E of the electric machine 4 and the rotational speed n V M of the internal combustion engine 1 are shown in FIG. 2 over the time t.
  • the internal combustion engine 1 is started by the alternatives described above.
  • the shiftable clutch 3 is closed. This is done by way of example in the time domain .DELTA.t of Figure 2.
  • the rotational speed difference .DELTA.n is advantageously compensated for by the hydrodynamic converter 2 until by closing of the hydrodynamic converter 2 associated lock-up clutch at time t 2, the direct flow of power from the engine 1 to the automatic transmission 5 is smoothly prepared , Thereafter, the vehicle is driven in common by the engine 1 and the electric machine 4 (E + VM travel).
  • Such a switching operation of the shiftable clutch 3 is particularly comfortable and jerk-free and is further characterized by the fact that the speed difference .DELTA.n when closing the switchable clutch 3 can be greater than if no hydrodynamic converter 2 between the engine 1 and electric machine 4 would be arranged.
  • the start of the internal combustion engine 1 and the above-mentioned closing the switchable clutch 3 do not affect the drive torque of the vehicle.
  • the vehicle can only be driven by the internal combustion engine 1, wherein the electric machine 4 does not pick up a moment or is operated as a generator.
