Source can be engine 4, dynamotor etc., secondly can be speed changer (including multiple input shafts, multiple output shafts, gear tooth
Wheel set etc.), speed changer is used to realize the speed changing function for exporting power source power, meets vehicle driving requirements or charging requirement
Deng.
For example, in certain embodiments, as Figure 1-Figure 2, power-driven system 100 can include engine 4, first
Dynamotor 51 and speed changer, but not limited to this.
With reference to shown in Fig. 1, in certain embodiments, speed changer mainly includes multiple input shafts (for example, the first input shaft
11st, the second input shaft 12), multiple output shafts (for example, the first output shaft 21, second output shaft 22), phase on reverse gear shaft 3 and each axle
Close gear and shifting element (e.g., synchronizer).
When entering action edge between engine 4 and input shaft and transmitting, engine 4 is arranged to be selectively engageable multiple defeated
Enter at least one in axle.In other words, for example, when engine 4 transmits power to input shaft, engine 4 can be optionally
Engaged with one in multiple input shafts to transmit power, or engine 4 can also optionally with multiple input shafts
Two or more input shafts are simultaneously engaged with to transmit power.
For example, in Fig. 1-Fig. 2 example, multiple input shafts can include 12 liang of the first input shaft 11 and the second input shaft
Root input shaft, engine 4 can be engaged optionally to transmit power with one of the first input shaft 11 and the second input shaft 12.Or
Person, especially, engine 4 can also be simultaneously engaged with to transmit power with the first input shaft 11 and the second input shaft 12.Certainly, should
Understand, engine 4 can also disconnect with the first input shaft 11 and the second input shaft 12 simultaneously.
For the ordinary skill in the art, the engagement state and power-driven system of engine 4 and input shaft
100 specific operating mode is related, and this will in conjunction with specific embodiments be described in detail, no longer describes in detail here below.
It can be driven between input shaft and output shaft by shift gear pair.For example, it is respectively provided with each input shaft
There is gear driving gear, gear driven gear, gear driven gear and gear driving gear pair are provided with each output shaft
Ground engagement is answered, so as to form multipair speed than different gear pairs.
The differential mechanism power input gear 7 of multiple output shafts and vehicle can be driven.Wherein, it is respectively provided with each output shaft
There is an output gear, one of output gear empty set is defeated to form the output shaft empty set of the output shaft on an output shaft wherein
Go out gear, output shaft empty set output gear is arranged to that the output shaft can be engaged.It is provided with remaining each output shaft defeated
Shaft fixes output gear, and wherein output shaft empty set output gear and output shaft fixes the output gear difference with the vehicle respectively
Fast device power input unit engagement.

On one of output shaft.As Figure 1-Figure 2, reverse output gear 39 is fixed on the second output shaft 22, can so be made
It is reasonable to obtain the position of reverse output gear 39, can further reduce the volume of power-driven system 100.
It should be noted that above-mentioned " linkage " can be understood as multiple parts (for example, two) coupled movements, with two
Exemplified by part linkage, wherein during a part motion, another part also moves therewith.
For example, in some embodiments of the invention, gear and axle linkage can be understood as when gear rotates and it
The axle of linkage also will rotation, or when the axle rotate, the gear that is linked with it will also rotate.
And for example, when the linkage of axle and axle can be understood as that an axle rotates wherein, another axle being linked with it also general
Rotation.
For another example, linked when gear and gear-linked can be understood as that a gear rotates wherein, with it another
Gear also will rotation.
In the description about " linkage " below the present invention, if without specified otherwise, it is understood in this way.
