Definitions

• the present invention relates to a hybrid vehicle with a dual-clutch transmission according to the preamble of claim 1.
• Hybrid vehicles have an internal combustion engine and at least one electric machine which can be operated as an electric motor and can generate propulsion.
• So-called "parallel hybrid vehicles” can either be driven purely by internal combustion engine technology, purely by electric motor or internal combustion engine and assisted by an electromotive engine.On purely electric motor drive, the internal combustion engine is usually switched off and started by an electrical machine if required single electrical machine for the electric driving operation electric power for the support of the internal combustion engine are kept, which requires a correspondingly large dimensioning of the electric machine.
• the electric machine between the engine and the transmission input is arranged for the support of the internal combustion engine Thus, in the normal case, no translation can be used, so that in the electric machine the starting torque required at the crankshaft of the internal combustion engine is maintained must be.
• the object of the invention is to provide a hybrid vehicle, wherein the internal combustion engine from the purely electric driving out with a comparatively small electrically applied torque can be started.
• the starting point of the invention is a hybrid vehicle having an internal combustion engine, a dual-clutch transmission and an electric machine coupled or coupleable to a transmission input of the dual-clutch transmission.
• a dual-clutch transmission is understood to mean a transmission with two partial transmissions, wherein one partial transmission has a first group of gear stages, e.g. odd gears, d. H. the gears 1, 3, 5, etc. are assigned, and the other sub-transmission a second group of gear stages, e.g. even gears d. h, the gear stages 2, 4, 6, etc. are assigned.
• dual-clutch transmissions have the advantage that time-overlapping switching operations without interruption of traction are possible.
• the transmission input of the dual-clutch transmission is for this purpose coupled via a first transmission clutch to a transmission input or an input shaft of the first sub-transmission and via a second transmission clutch to a transmission input or an input shaft of the second sub-transmission. If, for example, switched from the first to the second gear, the transmission clutch of a partial transmission is opened overlapping time and thereby designed the first gear while the transmission clutch of the second partial transmission is closed and the second gear engaged. "Outputs" of the two partial transmissions can be coupled or coupled to a common transmission output of the dual-clutch transmission.
• the electric machine can be coupled or coupled to the transmission input of the dual-clutch transmission.
• a purely electric driving in which the internal combustion engine is disconnected and switched off, is between the transmission input of the dual clutch gear and the internal combustion engine arranged a separating clutch.
• working as an electric motor electric machine drives the vehicle either on the gear ratios of the first sub-transmission or on the gear ratios of the second sub-transmission.
• a starter clutch is therefore provided according to the invention, which is also referred to as “starter clutch”, and which is arranged between the engine and the transmission input of the inactive Examplesszweigs, ie at a Dopplekupplungsgetriebe between the engine and the currently inactive partial transmission ,
• Figures 1-4 show various hybrid topologies according to the invention.
• FIG. 1 shows a hybrid concept with an internal combustion engine 1, an electric machine 2 and a dual-clutch transmission 3, which has a first partial transmission 4 and a second partial transmission 5.
• the first partial transmission 4 for example, the odd gear ratios 1, 3, 5, etc. and the second partial transmission 5, the straight gear ratios 2, 4, 6, etc. be assigned.
• a crankshaft 6 of the internal combustion engine is connected to a transmission input 9 of the dual-clutch transmission 3 via a separating clutch 7 and a torsional vibration damper 8, which may be a so-called dual-mass flywheel.
• the transmission input 9 of the dual-clutch transmission 3 in turn, can be coupled via a first clutch 10 and a gear stage 11 to a transmission input 12 of the first partial transmission 4.
• the transmission input 9 of the dual-clutch transmission via a transmission stage 14 with a transmission input 15 of the second sub-transmission 5 can be coupled.
• Outputs 16, 17 of the two partial transmissions 4, 5 are coupled to a transmission output 18 or can be coupled to the transmission output 18 of the dual-clutch transmission 3.
• the hybrid concept shown in Figure 1 furthermore has a starter coupling 19, via which the internal combustion engine 1 can be coupled to the first partial transmission 4.
• the starter coupling 19 is arranged kinematically parallel to the separating clutch 7.
• a “safety device” not shown here ensures that the Zustartkupplung 19 can only be closed when the clutch 7 is opened at the same time or is already open, and that the separating clutch 7 can only be closed when the same time the starter coupling 19th is opened or already open.
• the electric machine 2 can be switched on and feed additional torque into the drive train.
• the torque delivered by the internal combustion engine 1 and the torque delivered by the electric machine 2 can thus be superimposed on one another.
• the vehicle can also be driven purely by electric motor or braked regeneratively for recuperation of braking energy.
• the separating clutch 7 and the starting clutch 19 is opened.
• the torque delivered by the electric machine 2 passes via the torsional vibration damper 8 to the transmission input 9 of the dual-clutch transmission 3 and from there, depending on the engaged gear, via the first clutch 10 and the first partial transmission 1 to the transmission output shaft 18 or via the second clutch 13 and the second Partial gear 5 to the transmission output shaft 18th
• a partial torque can be diverted from the torque applied to the transmission output shaft and forwarded via the transmission output 16 of the then "inactive" partial transmission 4 in the direction of the internal combustion engine More specifically, the branched torque flows from the output 16 via the first partial transmission 4, the transmission input 12 of the first partial transmission 4, the transmission stage 11 and the starter clutch, which is closed to the start of the internal combustion engine 1, to the crankshaft 6 of the internal combustion engine 1.
• Figure 2 shows a variant of the embodiment of Figure 1.
• the electric machine 2 is arranged coaxially with the crankshaft 6 of the internal combustion engine 1 and thus coaxially with the transmission input 9 of the dual-clutch transmission 3.
• the torsional vibration damper 8 is arranged here directly between the crankshaft 6 of the internal combustion engine 1 and the "input side" of the separating clutch 7 or the starting clutch 19.
• Figure 3 shows a variant in which the torsional vibration damper 8 is arranged analogously as in the embodiment of Figure 2.
• the electric machine 2 is not coaxial with the crankshaft 6 of the engine or coaxial with the transmission input 9 of the dual-clutch transmission 3, but offset parallel thereto.
• the rotor 20 of the electric machine 2 is coupled via a transmission stage 21 to the transmission input of the dual-clutch transmission.
• a belt drive could also be provided.
• Figure 4 shows a variant of the embodiment of Figure 3, wherein in Figure 4, the torsional vibration damper 8 is arranged analogously as in the embodiment of Figure 1 between the clutch 7 and the transmission input 9.
