Shown in reference picture 1- Fig. 3, power engagement device 65a is arranged for engaging the first power output
Axle 43a and the second power output shaft 44a, so that the first power output shaft 43a and the second power
Formed between output shaft 44a and be rigidly connected, and then the first power output shaft 43a and the second power output
Axle 44a can be rotated in the same direction, at the same speed.That is, being in joint shape in power engagement device 65a
During state, the first power output shaft 43a and the second power output shaft 44a keeps synchronization action state,
When power engagement device 65a is off, the first power output shaft 43a and the second power output
Axle 44a can carry out differential rotation, i.e. the first power output shaft 43a and the second power output shaft 44a
Can respectively with different rotational speed (can certainly same rotational speed rotate).
Here, it is necessary to explanation, power engagement device 65a is for engaging the first power output shaft 43a
Should be broadly understood with the second power output shaft 44a, such as power engagement device 65a can directly connect
Close or disconnect the first power output shaft 43a and the second power output shaft 44a, alternatively of course, power
Engagement device 65a can also indirectly realize that the first power is defeated by engaging or disconnecting other two parts
The engagement of shaft 43a and the second power output shaft 44a with disconnect, two parts can be and first
The part that power output shaft 43a is connected with the second power output shaft 44a, such as the first planet carrier 14a
With the second planet carrier 24a.
Vehicle with power-driven system 100a according to embodiments of the present invention, such as vehicle 1000a
When traveling is in flat road surface and along straight ahead, the first brake apparatus 63a and the second brake apparatus 64a can
The first gear ring 13a and the second gear ring 23a, the first dynamotor 31a and the second dynamoelectric and power generation are braked respectively
Machine 32a can export power with identical rotating speed, right so by the decelerating effect of respective planetary gears
It is theoretically equal to answer wheel to obtain rotating speed, thereby guarantees that vehicle 1000a can smoothly along linear rows
Enter.
And for example, when vehicle 1000a travelings are in uneven road surface or turning driving, the first brake apparatus 63a
With the second brake apparatus 64a the first gear ring 13a and the second gear ring 23a can be respectively braked, now both sides
Can there is speed discrepancy in theory in the rotating speed of wheel, by taking left-hand bend as an example, the radius of turn of left side wheel it is smaller and
The radius of turn of right side wheels is larger, in order to ensure to make PURE ROLLING between wheel and ground, left side wheel
Rotating speed be less than the rotating speed of right side wheels, now the output speed of the first dynamotor 31a can be less than
The output speed of the second dynamotor 32a, and between specific speed discrepancy can be by the steering angle of steering wheel
Connect and calculate, such as driver rotates counterclockwise steering wheel (turning left) certain angle, vehicle 1000a
Controller be based on the steering angle and can calculate the radius of turn of vehicle 1000a, vehicle 1000a turns
After radius determines, the relative rotation speed difference of both sides wheel is also determined, now controller controllable first is electronic
Generator 31a and the second dynamotor 32a externally export power with the rotating speed for matching respectively so that the two
Speed discrepancy can be matched with the speed discrepancy needed for wheel, so made by the decelerations of two planetary gears
With rear, two wheels are obtained in that desired rotating speed, so as to realize pure rolling turning driving.
Above-mentioned is using the first dynamotor 31a and the second dynamotor 32a as explanation as a example by motor
, certain first dynamotor 31a and the second dynamotor 32a can also be used as generator operations.
Now, similarly, the first brake apparatus 63a and the second brake apparatus 64a can respectively brake the first gear ring
13a and the second gear ring 23a, the first dynamotor 31a and the second dynamotor 32a can then generate electricity
Machine form works, so as to reclaim braking energy.
It is, of course, understood that above-mentioned the first planetary gears 1a and the second planetary gears
2a can use identical gearratio, that is to say, that with sun crop rotation as power intake and planet carrier make
For for clutch end, two planetary gears can use identical gearratio.That is, first sun
Take turns 11a and the second sun gear 21a the number of teeth, the first planetary gear 12a and the second planetary gear 22a the number of teeth with
And first the number of teeth (internal tooth) of gear ring 13a and the second gear ring 23a can be identical respectively.
Especially, when vehicle 1000a travelings are under poor load conditions, for example vehicle 1000a is comparing
When being travelled on the road surface such as muddy or soft gravel road or sandy soil, by taking muddy road conditions as an example, vehicle
1000a may be absorbed in soil and cause idle running, that is to say, that vehicle 1000a there occurs that skidding (is beaten
Sliding phenomenon and the reason for cause skidding be well known to a person skilled in the art).
For differential mechanism of the tradition with auto-lock function, after skidding occurs in wheel, control is only needed
Differential mechanism self-lock, so as at least can to a certain extent improve the ability of getting rid of poverty of vehicle 1000a.
Because power-driven system 100a according to embodiments of the present invention has on differential function, but structure again
There is bigger difference with conventional carrier, it is impossible to using traditional differential self-locking structure.In order to improve vehicle
1000a by property, improve adaptability of the vehicle 1000a to poor road conditions, some embodiments of the invention
Power-driven system 100a on the premise of differential function is realized, moreover it is possible to further realize auto-lock function.
Some embodiments of the invention, for example, can combine shown in Fig. 1-Fig. 3, occur one in vehicle
During the wheel-slip of side, power engagement device 65a engagement the first power output shaft 43a and the second power output
Axle 44a, and the first brake apparatus 63a and the second brake apparatus 64a brake the first gear ring 13a respectively
With the second gear ring 23a, thus the first dynamotor 31a and the second dynamotor 32a will can be produced
The output of single wheel that raw power never skids, improves wheel-slip phenomenon, improve vehicle by energy
Power.
To sum up, power-driven system 100a according to embodiments of the present invention, by the first brake apparatus 63a
With the second brake apparatus 64a braking actions, it is possible to achieve the first dynamotor 31a and the second electronic hair
The electric-only mode or Brake energy recovery pattern of motor 32a, and by individually the first dynamoelectric and power generation of control
Machine 31a and the second dynamotor 32a output speeds, can make the wheel of both sides obtain different moments of torsion,
Realize differential function.Additionally, power-driven system 100a parts according to embodiments of the present invention it is few, knot
Structure is compact simple, takes small volume, arrangement of being more convenient for.
