  • a hybrid vehicle drive system is known from DE 11 2015 006 071 T5.
  • a power control unit is thereby directly mounted to a case-side generator connector and a case-side motor connector, which are arranged on the drive system case, by connecting a unit-side generator connector and a unit-side motor connector which are provided on a lower surface of the power control unit.
  • the drive system housing is fixed to a body frame by means of a mounting element, and a fixing point K2, where the drive system housing and the mounting element are fixed to one another, is arranged in the vicinity of the housing-side generator connector and the housing-side motor connector.
  • the European patent EP 1 847 411 B1 discloses a white direct hybrid drive.
  • a hybrid transmission having a differential unit with two degrees of freedom, formed by a single pinion planetary gear set and a double pinion planetary gear set which, together with the single pinion planetary gear set, holds a common carrier and which have five rotating parts from which, if Rotational states of two rotating parts are set, those of the other rotating parts are set; an input element of the hybrid transmission from an internal combustion engine that is connected to a ring gear of the double pinion planetary gear set is coupled; an output end of the hybrid transmission on a road wheel drive system coupled to the common carrier, a first motor / generator coupled to a sun gear of the double pinion planetary gear set; a second motor / generator coupled to a sun gear of the single pinion planetary gear set; and a brake to brake a ring gear of the single pinion planetary gear set.
  • an output element that outputs the rotation of the differential unit with two degrees of freedom from the common carrier to the road wheel drive system, between at least one of the first or second motor / generator on the one hand, and the single pinion Planetary gear set is arranged on the other side and the first and second motor / generator are formed by a two-layer motor driven by a composite current with inner and outer rotors and a stator.
  • a motor vehicle drive system is also known from EP 3081 390, which, however, differs from a drive system as it is known at the German Patent and Trademark Office with application number DE 10 19 132941.
  • This earlier registration of the inventor relates to a drive unit for a drive train of an electrically drivable motor vehicle, in particular a hybrid motor vehicle, with a first electric rotary machine and a second electric rotary machine and a first shaft and a second shaft, with a rotor of the first electric rotary machine rotatably is connected to the first shaft and a rotor of the second electrical rotating machine is non-rotatably connected to the second shaft and wherein the drive unit furthermore has a separating clutch with which the rotor of the first electrical rotating machine can be or is connected to the second shaft for torque transmission.
  • the special feature of this drive unit is that one of the two electric rotary machines is at least partially arranged radially and axially within a space that is radially delimited by the respective other electric rotary machine.
  • the present invention has set itself the task of reducing the disadvantages known from the prior tech technology or, in the best case, even solving them.
  • this object is achieved in that a generic hybrid vehicle drive train is redesigned so comprehensively that the hybrid vehicle drive train is mechanically designed so that the generator is (permanently) separated (/ disconnected) from the electric motor in all operating states.
  • Torque from the internal combustion engine is fed to the generator, with the generator providing power to the electric motor for the subsequent drive.
  • the torque made available by the electric motor is then fed to the drive wheels via a transmission, preferably comprising a differential gear.
  • a purely serial drive of the hybrid vehicle becomes possible. It is accepted that a purely internal combustion engine vehicle drive is no longer possible. This is acceptable because, particularly in the case of hybrid vehicle classes, which are essentially designed for vehicle speeds below 130 km / h, a vehicle drive solely powered by an internal combustion engine can be dispensed with. Here, with increasing vehicle speed, an efficiency that is less positive than that of internal combustion engines no longer has such a strong effect.
  • the savings potential due to the omission of the separating clutch and an actuation unit are much more significant when considering a design that is much more compact in terms of installation space.
  • the generator has a rotor that is designed as an internal rotor and the electric motor has a rotor that is also designed as an internal rotor.
  • both rotors can also be designed as external rotors.
  • the generator has a rotor that is designed as an internal rotor and the electric motor has a rotor that is designed as an external rotor. This enables a particularly compact embodiment.
  • a good utilization of the installation space is also beneficial if the generator and the electric motor are nested in one another.
  • the transmission is present in the torque flow downstream of the electric motor and preferably has an intermediate shaft upstream of a differential transmission, a particularly wear-free torque transmission can be achieved.
  • a translation of ii is implemented between the internal combustion engine and the generator, a translation of is implemented between the electric motor and the intermediate shaft and a translation of is implemented between the intermediate shaft and the differential, where ii is h.
  • the ratios 11, 12 and h could also be the same.
  • a damper and / or a countershaft transmission is present between the internal combustion engine and the generator. Especially that Countershaft transmission enables the electric motor to be operated in a desired range of revolutions.
  • the invention also relates to a hybrid vehicle with a hybrid vehicle drive train according to the invention.
  • the inventive solution to the problem is to realize a two-electric machine transmission for serial vehicles with two coaxially arranged electric machines, one of the two electric machines being designed as a generator (EM1) and the other as a driving machine (EM2) .
  • EM1 generator
  • EM2 driving machine
  • Two electrical machines arranged coaxially and positioned next to one another are used.
  • the two electric machines are arranged coaxially to one another, but nested one inside the other, with the rotor leading out as an internal rotor in the generator and the rotor as an external rotor in the driving machine.
  • the two electric machines are arranged coaxially to one another, but also nested one inside the other, with the two rotors here leading out as internal rotors in the generator and in the driving machine.
  • the vehicle driving modes that are possible with the two-electric machine transmission according to the invention are not known from the prior art.
  • the most significant main feature of the invention disclosure, however, is the coaxial arrangement of the electrical machines.
  • the driving strategy of the serial drive of a hybrid vehicle according to the invention is structured as follows:
  • the internal combustion engine is connected to the electric machine, which is designed as a generator, in a torque-locking manner by means of a drive shaft.
  • the internal combustion engine and the generator are preferably connected to one another by means of a translation ii.
  • a damper is connected in the torque flow between the generator and the internal combustion engine.
  • the electric machine that is designed as a driving machine is connected to the vehicle drive (drive shaft / vehicle wheels) to transmit torque. This connec tion is preferably made via two translation stages and h.
  • the transmission stage is present between the electric machine and an intermediate shaft.
  • the transmission stage is between the intermediate shaft and the differential. As there is no separating clutch and an actuating element, there is no mechanical torque-transmitting connection between the internal combustion engine and the vehicle drive.
