Background technique
Within the scope of this specification, simple double-planet group is interpreted as following planetary set, and the planetary set is in addition to sun part, sky
Other than the first subgroup and the second subgroup of heart wheel and bridge part and planetary gear (planetary gear is so supported on bridge part, so that
The planetary gear and sun part of first subgroup, the planetary gear of the second subgroup are mutually nibbled with the planetary gear of hollow wheel and the two subgroups
Close), it does not include other transmission mechanism relevant element topologically.Such planetary set is also synonymously referred to as simple herein and adds
Formula planetary set.
Such driving assembly is as known to 10 2,014 215 092 A1 of DE.
Within the scope of this specification, " connection " this concept with constant rotating ratio for example via being fixedly connected
Or it is used under the connection meaning realized of immutable speed change grade.In contrast, " coupling " this concept not only includes this kind of turn
The constant connection of speed ratio, and including connection that is changeable or changing.If referring specifically to latter case, usually at large say
Bright corresponding switching element.But if referring specifically to first situation, usually abandon advantageous using " coupling " this concept
In " connection " this specific concept." coupling " this concept is used usually to anticipate in the case where not illustrating specific switching element
Taste two situations are included intentionally.When referring to the torque temporarily realized under the special switching state of switching element
When transmitting or support, " temporarily connecting " this statement also can be used.The differentiation is carried out only to be conducive to better understand simultaneously especially
It is in order to illustrate, and mandatory requirement is arranged changeable or variation connection rather than can usually be easier the rotating ratio realized at this
Constant connection.Therefore the definition of the upper surface of " connection " this concept also so should not be explained straitly under any circumstance, make
Obtaining the switching element being arbitrarily embedded in detour purpose will be implemented by its literal meaning.
The published document for starting the internus referred to discloses a kind of epicyclic transmission mechanism, in the feelings of the epicyclic transmission mechanism
Under condition, simple double-planet group and La Weinaierhe group are arranged on common bridge part.The sun part and sky of first planetary set
The first sun part or the first hollow wheel should be simplifiedly known as below heart wheel.According to definition, La Weinaierhe group has La Weinai
The conspicuous hollow wheel of that, the intermeshing row of small La Weinaierhetai male part, big La Weinaierhetai male part and two subgroups
Star-wheel.Here, small La Weinaierhetai male part is engaged with the planetary gear that the construction of the first subgroup is short planetary member.La Weinaier
Conspicuous hollow wheel is engaged with the planetary gear that the construction of the second subgroup is long planetary member.Big La Weinaierhetai male part is equally with second
The long planetary member of subgroup engages.The two hollow wheels are respectively via direct gear stage and common intermediate axis connection, among this
The output shaft of axis and driving assembly is identical.The two hollow wheels are fixed to one another in terms of its rotating ratio and with not as a result,
Same speed change and jackshaft or output axis connection.The common bridge part of epicyclic transmission mechanism is via main connecting piece and internal combustion engine-
Input shaft couples.Via switching element more than two (different cut may be implemented using more switching elements in these three sun parts
Change situation) with internal combustion engine-input shaft, with electric motor-input shaft, with transmission mechanism shell and each other couple.Four changes
Fast grade can respectively by electric motor power, combustion engine powered ground or it is parallel mixed realize and can be realized dynamicly it is multiple stepless
Operational mode.Powerful the mixing of power that this kind of driving assembly is best suitable for the maximum speed that band has more than 250km/h is moved
Vehicle.However, the driving assembly requires not being inapparent axial arrangement space, the structure space is in lower vehicle rank
(most of the lateral of setting combustion power machine are packed into the vehicle rank) is often disabled.However, this kind of vehicle
On the other hand most of all conceptual designs are powerful at less power, thus be not strictly required yet a large amount of different operational modes,
Especially with the operational mode of the speed change grade of four relative high numbers.
Summary of the invention
Task of the invention lies in the significant size reductions of known driving assembly, thus abandoning high-speed cruising mould
Axial arrangement space can be saved in the case where formula, without generating disadvantage in low speed and moderate speed range.
The feature of the preamble of the task combination claim 1 solves in the following way: the second planetary set is same
It is configured to simple double-planet group.
The preferred embodiments of the present invention is the theme of dependent claims.
Core of the invention is to reduce the known La Weinaierhe planetary set in epicyclic transmission mechanism to having
Second simple double-planet group of the second hollow wheel and only one second sun part.I.e. compared to the prior art of internus, especially
Abandoning big La Weinaierhetai male part includes its connecting piece.The row of second subgroup of the planetary gear in the second planetary set as a result,
Star-wheel equally can be structured as short planetary member, thus correspondingly save axial arrangement space.Switching element, such
The cancellation for being responsible for component as the connection of big La Weinaierhetai male part in the prior art also brings further structure empty
Between save.Certainly, some operational modes are also cancelled by this saving of the second planetary set and simplification.However, only relating to herein
High-speed mode, the high-speed mode only extremely use less anyway in the powerful mixed motor-car of less power.According to the present invention
Driving assembly in the case where, which can also especially pass through operation to be moreed specifically explain, stepless further below
Mode substitutes.More inefficient operation due in the velocity interval of the stepless operational mode in high-speed range is lacked
It is sexual and energy it is overall consider under be unessential.More precisely, size reduction according to the present invention also due also to
This associated weight save and at priority level (Premiumklasse) gross efficiency of the lift pins to mixed motor-car.
As being also preferably provided in the prior art, the hollow wheels of the two planetary sets carry each outer toothed portion and by
This is via each gear stage and intermediate axis connection.The jackshaft can be identical with output shaft.However according to the present invention
In the case that driving assembly is laterally packed into a motor vehicle, this can cause about radially typically adjoining driven
The aforesaid structure space problem of component.Therefore, instead of the jackshaft that extends in the whole length of epicyclic transmission mechanism it is preferable that
At the hollow wheel that driven device is directly coupled in hollow wheel.In other words, be arranged in this embodiment, output shaft with
A hollow wheel in hollow wheel is identical.I.e. the outer toothed portion of the hollow wheel is directly engaged with driven device, especially differential carrier.
In this embodiment, jackshaft peripherally can be engaged movably at other positions with the outer toothed portion of hollow wheel in direction.It is right
This, can choose the position of structure space required for each offer along the periphery of epicyclic transmission mechanism in principle.
In order to switch between each operational mode, the switching element referred to beginning is needed to manipulate.This is general

Mode is illustrated by the power flow that it is accordingly realized.
Fig. 2 shows the modified embodiment of driving assembly according to the present invention, which should only borrow herein
Its difference with Fig. 1 is helped to illustrate.In the embodiment of Fig. 2, jackshaft 4 is not identical with output shaft 3.The latter is more precisely
Say that with the second hollow wheel 22 be identical in ground.Unshowned driven device can be radially compressed close to epicyclic transmission mechanism as a result,
This is especially in the case where driving assembly according to the present invention is laterally encased in motor vehicle in terms of required structure space
It is advantageous.It is intermediate in order to equally realize the fixation functionally of rotating ratio being illustrated above, between hollow wheel 21,22
Axis 4 is set as additional axis, and is placed along other angular positions of the periphery of epicyclic transmission mechanism.The jackshaft
Specific angle orientation can according to respectively in single situation existing structure space condition and largely freely

Axis 1 not instead of coaxially in the axis of centres arrangement of the carrying bridge part 30 of epicyclic transmission mechanism, is not radially staggered ground and via commutating tooth
Take turns grade connection.
Furthermore, it is possible to reference to the explaination for Fig. 1.It is next, with reference to Fig. 1 embodiment for achievable operation
The explaination that mode is carried out is easily transferred into the embodiment of Fig. 2 in which can also make necessary amendment.
Fig. 3 shows the driving assembly under the first switching condition of Fig. 1, presents in the case where first switching condition single
First gear of pure electric vehicle.Main connecting piece 61 is opened, so that internal combustion engine is decoupled.Here, more switching elements 62 are so adjusted, make
It obtains bridge part 30 to connect with electric motor-input shaft 2, and the first sun part 11 is fixed at transmission mechanism shell 70.And the
Two sun parts 12 can be freely rotated, so that only the first planetary set works on transmission technology.Due to first planetary set
The first sun part 11 for being kept fixed, first planetary set effect to be being imported for electric motor 80 via bridge part 30 and
The simple speed change grade of the torque at output shaft 3 is exported to via the first hollow wheel 21.
The switching condition of Fig. 4 is different from such switching condition of Fig. 3 by the closure of main connecting piece 61, thus additional
Torque can be guided to from bridge part 30 from internal combustion engine, and motor vehicle can be run under the parallel mode mixed and moved.At this
It also can be realized under mode: running to 80 generator-type of electric motor.
Fig. 5 shows the switching condition of simple the first combustion engine powered gear, and under first gear, main connecting piece 61 is aobvious
So it is closed for the coupling of internal combustion engine.And more switching elements 62 are in following switching position, and in the switching position, only
One sun part 11 is fixed at transmission mechanism shell 70.Electric motor-input shaft 2 is decoupled completely.Also without realization via more
Second sun part 12 of switching element 62 or the temporary connection of bridge part 30.
Fig. 6 is shown below switching condition, and simple the second electronic gear is realized in the case where the switching condition.Main connection
Part 61 in order to internal combustion engine decoupling and open.More switching elements 61 are in following switching position, in the switching position, first
Sun part 11 is temporarily connect with electric motor-input shaft 2, and the second sun part 12 is fixed at transmission mechanism shell 70.
It is fixed by this, the effect of the second planetary set is relevant speed change grade, the torque warp with preset pre- speed change of electric motor 80
It is directed in the speed change grade by the first sun part 11 and bridge part 30.By the torque of speed change via second in the second planetary set
Hollow wheel 22 directs at output shaft 3.
The switching condition of Fig. 7 is different from the switching condition of Fig. 6 by the closure of main connecting piece 61.Additional torque as a result,
It can be imported from internal combustion engine via bridge part 30, to realize that the parallel of motor vehicle mixes dynamic operation.Also can in this mode
Realize the operation of the generator-type of electric motor 80.
Fig. 8 is shown below switching condition, and simple the second combustion engine powered gear is realized in the case where the switching condition.
Here, main connecting piece 61 is clearly to be closed.More switching elements 62 are in following switching position, in the switching position, only
Second sun part 12 is fixed at transmission mechanism shell 70.Electric motor-input shaft 2 is decoupled completely.Similarly for first sun
Part 11 and bridge part 30 do not realize temporary connection in more switching elements 62.
Fig. 9 is shown below switching condition, and simple electronic direct gear is realized in the case where the switching condition.Here,
Main connecting piece 61 in order to internal combustion engine decoupling and open.More switching elements 62 are in following switching position, in the switching position
In, bridge part 30 and the second sun part 12 are fixed on each other.Cause the complete locking of epicyclic transmission mechanism as a result, thus
Two planetary sets are surround in the case where not internal relative rotation as block.This is real around being come with the revolving speed of electric motor 80
It is existing, because electric motor-input shaft 2 is temporarily connect with the second sun part 12 or bridge part 30 by means of more switching elements 62.
The switching condition of Fig. 4 is closed to be different from switching condition as Fig. 9 by main connecting piece 61.It is additional as a result,
Torque can be imported from internal combustion engine.Obviously, internal combustion engine and electric motor 80 can only be with phases under the parallel mixed dynamic direct gear
With der Geschwindigkeitkreis around.It also can be realized the operation of the generator-type of electric motor 80 herein.
Other than the operational mode with fixed speed change being illustrated above, also it may be implemented with infinitely variable
The operational mode of speed change.
These operational modes illustrated in figs. 11 and 12 are to mix dynamic property respectively.It is interior under the switching condition of Figure 11
The torque of combustion engine is imported into bridge part 30 via the main connecting piece of closure.More switching elements 62 are in following switching position,
In the switching position, the first sun part 11 is connect with electric motor-input shaft 2, and for the second sun part 12 and bridge part
30 are not provided with temporary connection in more switching elements 62.The second sun part 12 that second planetary set is freely rotated due to it is therefore
It does not work on transmission technology.And the speed change of the combustion engine powered torque in the first planetary set depends on the first sun part
11 rotation status, the rotation status are determined by the operation of electric motor 80.When electric motor 80 is static, which is corresponded to
Fig. 3 such situation.But in the case where electric motor 80 (just or instead) rotation, the revolving speed of the electric motor can acted on
It is used for the stepless variation of its initial speed in the first planetary set to be added formula transmission mechanism.
Under the switching condition of Figure 12, the situation is similar, and with following difference: the second planetary set is used as being added herein
Formula transmission mechanism, mode are that the second sun part is temporarily connect with electric motor-input shaft 2 by means of more switching elements 62.
Combustion engine powered torque herein is also directed in bridge part 30 via the main connecting piece 61 of closure.Under the switching condition,
First planetary set does not work on transmission technology, because the first sun part 11 of first planetary set is due to more switching elements 62
Switching position and can be freely rotated.Temporary connection is not provided in more switching elements similarly for bridge part 30.
Figure 13 is finally shown below switching condition, not shown in the figure, via power electric device under the switching condition
The energy accumulator connecting with electric motor 80 passes through the case where vehicle for operating in stopping of the generator-type of electric motor 80
Under can charge.Here, more switching elements 62 are in following position, in this position, only bridge part 30 and electric motor-are defeated
Enter axis 2 temporarily to connect.And two sun parts 11,12 are not provided with connecting in more switching elements 62, thus these elements
It is freely rotated, thus entire epicyclic transmission mechanism does not work on transmission technology.Being imported via the main connecting piece 61 of closure,
Therefore combustion engine powered torque is not delivered on output shaft 3.More precisely, torque revolving speed driven generator formula in the same manner
The electric motor 80 of ground operation.
Certainly, of the invention be used as only is presented discussed in the special description and in embodiment shown in figure
The embodiment of explanation.In scope of the disclosure herein, the modification feasible program of wide type can give art technology
Personnel.The switching condition realized herein by means of main connecting piece 61 and more switching elements 62 also especially can additionally, especially be led to
