Studying in great detail before motor EM is attached to transmission components 3 or 4 place via planetary gearbox level 9, first allow the other parts that hybrid drive assembly 1,2 is described in detail.
The efferent 7 of transmission components 3,4 is functionally connected effectively with change-speed box 14.In particularly preferred design plan, hybrid drive assembly 1,2 is at outgoing side and be linked (see Fig. 1 and 3) with the change-speed box 14 of the form of double-clutch speed changer.To this, efferent 7 is functionally connected effectively with double-clutch 15.Double-clutch 15 has two friction clutches K1, K2.Friction clutch K1, K2 such as can be configured to lamella clutch.Efferent 7 can be formed by common outer plate carrier (Au enlamellentr ger) at this.Therefore common outer plate carrier is the part of transmission components 3,4.
Hybrid drive assembly 1,2 is configured to mixing module, and wherein, when assembling, this mixing module forms a structural unit.This mixing module or hybrid drive assembly 1,2 have double-clutch 15.Mixing module can be arranged between combustion engine 8 and change-speed box 14 at this.Double-clutch 15 to be connected with two input shafts 16,17 at outgoing side and maybe can be connected.
These two input parts (i.e. combustion engine input part 5 and motor input part 6) and efferent 7 torsionally interconnect into and combustion engine input part 5 and motor input part 6 and efferent 7 rotating speed are operated in the same manner.Transmission components 3,4 can be made up of multiple component or parts at this, itself however when without speed change level (ü bersetzungsstufe) in the middle of connect form torque transfer element (Drehmoment ü bertragungsglied) or torque transfer chain (Drehmoment ü bertragungskette).
Shortcoming mentioned by beginning is avoided now thus, and namely sun wheel 10 forms motor input part 6.There is provided a kind of hybrid drive assembly 1,2 of compact structure thus, its combination especially meets structural limitations with the change-speed box 14 of the form of double-clutch speed changer.Hysteresis loss in this loss relevant to rotating speed, sheet group (Blechpaket) such as at motor EM or copper loss are lost and are driven skin effect (Stromverdr ngung) by the electric current in the coil of motor EM and at least reduce.Motor EM can be designed in narrower rotating speed band (Drehzahlband), so to obtain higher efficiency and power density.The efficiency optimization of motor EM and the design that power density is high is possible, to reduce the working speed of motor EM.
Next allow to study the hybrid drive assembly 1 according to Fig. 1 in great detail:
Hollow wheels 12 is arranged in housing 18 place with being fixed on housing place.Thus bridging part 13 and with the motor input part 6 of the form of sun wheel 10 can with regulation speed ratio relative to each other rotate.The rotor of unshowned motor EM is connected with the bridging part 13 of planetary gearbox level 9 in FIG.Corresponding speed change is there is now between bridging part 13 to sun wheel 10.Sun wheel 10 is torsionally attached to or is integrally configured to transmission components 3 place.In particularly preferred design plan, be provided with now electric motor clutch 19, wherein, bridging part 13 can torsionally be connected with transmission components 3 with electric motor clutch 19.By closed electric motor clutch 19, realize motor EM and be directly attached to transmission components 3 place.Bridging part 13 and sun wheel 10 at this with identical rotation speed operation.
Can realize now different traveling strategies thus.Time in, scope such as between 0 and 80km/h lower at moving velocity, the closed and motor EM of electric motor clutch 19 runs in lower, medium range of speed.This range of speed such as can between 0 and about 3000 rpms.Corresponding torque characteristic curve 20 is shown in Figure 3.Because motor EM is directly linked with transmission components 3, shown torque characteristic curve 20 not only corresponding to the torque sent by motor EM and also corresponding to provided by motor EM, the torque of the transmission components 3 that is present in efferent 7.Bridging part 13 and sun wheel 10 are pinned and synchronous rotary via electric motor clutch 19 at this.Open now electric motor clutch 19 when being greater than 80km/h and so cause the rotating speed speed change between motor EM and transmission components 3 when moving velocity is higher, such as.The rotating speed producing motor EM thus reduces.Torque is raised corresponding to speed change.
Show in phantom now torque characteristic curve 21 in fig. 2.Torque characteristic curve 21 is corresponding to the torque being present in transmission components 3 place of motor EM.Transmission components 3 at this to be greater than 3000 turns, rotating speed especially between 3000 and 7000 rpms rotates.Owing to carrying out rotating speed speed change by means of planetary gearbox level 9 now, motor EM, that is the actual speed of the rotor of motor EM less and treat that the torque applied by motor EM is higher, as by torque characteristic curve 22 appreciiable for this reason.Especially large between 1500 rpms and 3500 rpms at the rotating speed of these higher speed lower rotor parts or bridging part 13.The rotating speed of motor EM is lowered relative to directly engaging at this.Utilize the transmission system-topology of hybrid drive assembly 1 can produce rotating speed speed change by opening electric motor clutch 19 between motor EM and transmission components 3 now.Thus, motor EM can facilitate required moment with reducing corresponding to this speed change rotating speed.Between bridging part 13 and sun wheel 10, such as can there is the speed ratio of i=2.87 at this, produce the torque characteristic curve 20,21,22 according to Fig. 2 with this.By this branched power of planetary gearbox level 9, motor EM can two grades be attached to transmission components 3.At this, motor EM and combustion engine 8 can run parallel.In addition, this assembly has this advantage, and the oily spatter loss relevant to rotating speed that can reduce in the air gap of motor EM loses.
Allow below to study hybrid drive assembly 2 in detail according to Fig. 3 and 5.In this design plan, present bridging part 13 is arranged in housing 18 place with being fixed on housing place.The rotor 26 of motor EM is connected with hollow wheels 12.Speed change is there is thus between sun wheel 10 and hollow wheels 12 or between motor input part 6 and rotor 26.This design plan relates to the single grade link of motor EM to transmission components 4 place.Be not provided with electric motor clutch.This has this advantage, has namely saved component and has therefore saved structure space.The torque of motor EM be preferably designed so that in this design plan than at motor EM according to higher in the design plan of Fig. 1 and 2.This realizes by improving the quantity of the volume circle in coil.From transmission components 4, for motor EM rotating speed by reduction of speed, the mensuration voltage of motor EM does not change pulling in operation thus.
Stator 27 is arranged in housing 18.Housing 18 has sidewall 28 at this.Be configured with multiple pin 29 extended in the axial direction at sidewall 28 place, wherein, pin 29 at this as the bridging part 13 being fixed on housing place.Satellite gear 11 can be rotated to support on pin place and is in and engages with sun wheel 10 and hollow wheels 12 and engage.Hand of rotation between sun wheel 10 with hollow wheels 12 is contrary, and the hand of rotation thus between combustion engine with motor EM is also oppositely contrary in other words.
The maximum torque about rotating speed motor EM is shown in the diagram by characteristic curve 23.The torque (it is present in transmission components 4 place) of the corresponding attenuating of motor EM is shown by characteristic curve 24.At this, rotating speed of motor EM is reduced by planetary gearbox level 9.Maximum required rotating speed or design speed are preferably in the scope of 5000 rpms, especially and are less than 5000 rpms.The design speed of motor EM especially can be less than 5000 rpms, especially be less than 4000 rpms.The maximum rotating speed of transmission components 4 in this case about 7000 rpms.
Planetary gearbox level 9 especially can realize i be greater than 2.5 especially i=2.87 from motor EM to the speed ratio (i) of transmission components 3,4.The loss with frequency dependence in motor EM is at least reduced by hybrid drive assembly 1,2 described herein.To this, motor EM is attached to transmission components 3,4 place like this via planetary gearbox level 9, makes to avoid high engine speed range in the operation of motor EM.Centnifugal force in rotor 26 and rotating speed square proportional.Reduce therefore also to reduce centnifugal force by rotating speed.
Realize inserting neutral for the motor EM structure space of the branched power with less design speed in existing driving-topology (see Fig. 1).By application planetary gearbox level 9, this can be diverted to double-clutch speed changer in current structure space convention.Compared with hybrid drive assembly 1, hybrid drive assembly 2 has this advantage, does not namely need other electric motor clutch.But hybrid drive assembly 1 has this advantage, namely in the branched power with transmission components 4 or transmission components 3, there is larger clearance envelope about the traveling strategy of motor EM.
Owing to being provided with an only planetary gearbox level 9, hybrid drive assembly 1,2 can manufacture and build compactly in cost advantages ground.By applying the change-speed box 14 of subordinate, there is the possibility that synchronization is provided via motor EM in change-speed box 14.
Because the design speed of motor EM is lowered, the structure of the change of motor EM may be selected.Such as can consider that the corresponding coil of motor EM has the conductor be made up of rectangular metal line.Conductive wire cross-section can be enhanced at this.Effective cross section such as can be 2.5mm
2.Owing to can apply the wire with larger cross-sectional plane, the assembling of motor EM is simplified, because must provide less wire and corresponding interface for coil.By larger conductors cross, less conductor must be arranged in the corresponding groove of coil.Reduce thus for connecting up and the expending of insulation of coil.Because the rotating speed of rotor 26 reduces, rotor 26 is not loaded by so large centnifugal force.The sheet of rotor 26 may be designed so that the magnetic degree of utilization of fragment is enhanced thus.
