Definitions

• the invention relates to a drive train for a vehicle, in particular an electric vehicle with a rank extender, with a first electric machine, which is drive-connected via a planetary gear, which has a first, second and third planetary gear element, with at least one drive shaft of the vehicle, with a second electric Machine, which is connected via the planetary gear with the first electric machine, and with an internal combustion engine, which is connected to the first electric machine.
• the US 5,991,683 A discloses a drive train for a hybrid vehicle having a first electric machine and a second electric machine, and an internal combustion engine, wherein the first electric machine is connected to a sun gear of a planetary gear and the second electric machine is rigidly drive-connected to the planet carrier of the planetary gear , The second electric machine is further rigidly connected in drive with an internal combustion engine.
• the ring gear of the planet carrier acts on drive shafts of the vehicle. Coupling elements between the machines are not provided. However, this significantly limits the scope of the drive train. In particular, a decoupling of the second electric machine from the internal combustion engine or from the planetary gear is not possible.
• the range extender should also be able to be used in the short term to support the electric drive.
• the drive train should take up as little space as possible.
• a switchable first clutch is arranged, preferably between the second electric machine and the planetary gear, a switchable second clutch is arranged.
• the internal combustion engine can thus be decoupled from the second electric machine, whereby the second electric machine can be operated independently of the internal combustion engine, for example, to support the recuperation work, or to drive auxiliary equipment, such as an air conditioning compressor.
• the second electric machine can be decoupled from the planetary gear via the second clutch, it is also possible to recharge the electric accumulator independently of the remaining drive train via the internal combustion engine and the second electric machine. Nevertheless, by closing the first and the second clutch, a drive connection to the rest of the drive train can be established, whereby both the internal combustion engine, and the second electric machine can be used to support the drive power.
• the first electric machine may be drive-connected to a first planetary gear element preferably formed by a ring gear.
• a preferably formed by a planet carrier second planetary gear element acts on the drive shaft of the vehicle.
• the second electric machine is connected to the second planetary gear element.
• the second electric machine and the internal combustion engine can be used directly to support the drive of the drive shaft. This allows switching without train interruption, since the second electric machine can provide the torque for the drive at short notice during the switching process.
• the second electric machine is connected to the first planetary gear element.
• the second electric machine and the internal combustion engine act on the same planetary gear element as the first electric machine.
• the drive of the vehicle is thus performed by the internal combustion engine and the second electric machine via the translation of the planetary gear.
• a particularly high torque is available on the drive shaft.
• this also makes it possible to make the drive train more compact and easier, since the drive torque is provided by both electric machines.
• At least two different gear stages can be realized in a simple manner, when the first planetary gear element and the second planetary gear element via a switchable third clutch rigidly rotating together are bindable, preferably preferably formed by a sun gear third planetary gear element is firmly held by a braking device.
• gear ratios of 1: 1 and 1.5: 1 can be made possible.
• an air-conditioning compressor preferably via a transmission stage, is drive-connected to the second electric machine.
• FIGS. show schematically:
• FIG. 1 shows a drive train according to the invention in a first embodiment
• FIG. 2 shows a drive train according to the invention in a second embodiment.
• the Fig. show a drive train 1 for a hybrid vehicle with a first electric machine 2, a second electric machine 3 and an internal combustion engine 4, which, among other things, performs the function of a so-called range extender.
• the first electric machine 2 which in the present example forms the primary drive source, acts via its drive shaft 2 a on a first planetary gear element 5 a of a planetary structure 5 formed by a ring gear in the present exemplary embodiments.
• An example formed by a planet carrier second planetary gear element 5b is connected via a gear stage 6 and a differential 7 with drive shafts 8 of the vehicle.
• the drive shaft 3a of the second electric machine 3 can be connected via a switchable first clutch 9 with the shaft 4a of the internal combustion engine 4.
• the shaft 3b of the second electric machine 3 via a second clutch 10 with the planetary gear 5 is connectable.
• the first planetary gear element 5a and the second planetary gear element 5b of the planet carrier can be rigidly connected to each other.
• the third planetary gear element 5c formed, for example, by the sun gear can be held in place by a brake device 12.
• the drive shaft 3b of the second electric machine 3 is connected via a gear 13 with an air conditioning compressor 14.
• the drive shaft 3b of the second electric machine 3 can be connected via the second clutch 10 to the second planetary gear element 5b, which acts directly on the drive shafts 8 via the gear stage 6 having a rigid transmission ratio and the differential 7. In this way, a drive assist by the second electric machine 3 and / or the internal combustion engine 4 can be realized at high vehicle speeds.
• Fig. 2 shows an embodiment in which the drive shaft 3b of the second electric machine 3 via the second clutch 10 with the first planetary gear element 5a of the planetary gear 5 is drive-connected.
• the second electric machine 3 and / or the internal combustion engine 4 thus act - as the first electric machine 2 - on the input of the planetary gear 5, whereby the torque acting on the drive shaft 8 of the supporting second electric machine 3 and the internal combustion engine 4 by the switching position of the third clutch 11 and the braking device 12 depends dependent current gear ratio of the planetary gear 5.
• the gear ratio of the planetary gear 5 can be changed by alternately activating or deactivating the third clutch 11 and the braking device 12, wherein in the embodiment, when activated third clutch 11 and deactivated braking device 12, a transmission ratio of 1: 1 (direct drive), at deactivation of third clutch 11 and activation of the braking device 12, a gear ratio of 1.5: 1 between the first planetary gear element 5a and the second planetary gear element 5b sets.
• the maximum torques of the first electric machine 2, the second electric machine 3 and the internal combustion engine 4 behave in a ratio of 4: 2: 1.
• the first clutch 9 is closed to start the internal combustion engine 4 and to charge the electrical energy storage when the internal combustion engine 4 is activated.
• the first clutch 9 may possibly also be closed when torque assistance for acceleration by the internal combustion engine 4 is desired or necessary.
• the second clutch 10 is closed when the second electric machine 3 is activated to assist acceleration or recuperation.
• the second clutch 10 is open when the internal combustion engine 4 as Range Ex- tender is used only for charging the electrical energy store.
• the rotor of the second electric machine 3 can form the flywheel for the internal combustion engine 4.
• the internal combustion engine 4 forming the range extender is thus part of the drive train 1 and, together with the two electrical machines 2, 3, forms a compact system which requires only damping and insulation.
• the range extender can be used both for charging the electric battery storage, as well as for applying an additional torque, for example during a switching operation of the prime mover.
• Both electric machines 2, 3 can be used for recuperation.
• Each component of the drive train 1 can be independently activated or deactivated.
• the drive system 1 described thus represents a very compact arrangement for a hybrid vehicle with range extender and opens up a variety of different applications.
