It will be appreciated to those of skill in the art that oil pump 8 drives it typically by the motor being connected with its rotating shaft
Output hydraulic oil is rotated, in order to further simplify the structure of two shift transmissions power assembly of the present utility model, can be used
Integrated motor oil pump is that brake 6 and clutch 7 provide power respectively.Those skilled in the art are also understood that, are
The oil pump 8 is controlled respectively to brake 6 and clutch 7, also set between oil pump 8 and pipeline or on pipeline
Corresponding valve group is equipped with, the valve group includes but are not limited to reversal valve, unloading valve and overflow valve.
Further, pure electric automobile of the present utility model also includes control unit, the control with two shift transmission power assemblies
Portion is used to control but be not limited only to oil pump 8 and valve group, can make electric automobile according to road conditions to clutch by control oil pump 8 and valve group
Device 7 and brake 6 carry out sliding wear control, realize that electric automobile switches gearratio (gearshift) in the case where not interrupting power, from
And improve the power performance and comfortableness of vehicle.
With continued reference to Fig. 1, it is not difficult to find out from the figure, clutch 7 and brake 6 are all in disengaged position, and planet tooth
Take turns mechanism 5 has three degree of freedom in this condition (i.e. sun gear 51, external toothing 52 and planetary gear 53 can be rotated).Therefore
When input shaft 2 is rotated, in the presence of output resistance (load), sun gear 51 drives the original place of planetary gear 53 to rotate, external toothing
52 are forced to rotate along the direction opposite with the rotation direction of sun gear 51, cause the unpowered output of output shaft 3.Now, electric automobile
In neutral position state.Electric automobile is briefly explained with reference to Fig. 2 and Fig. 3, and two gears become in a gear state and when two keep off state
The power transmitting procedure of fast device.
As shown in Fig. 2 the figure shows the power transmitting procedure of electric automobile two shift transmissions in a gear state.This
When, the brake driving disc spacing pressing 61 and the phase of brake clutch plate 62 of brake 6 are caused in the presence of the hydraulic oil that oil pump 8 is exported
Engagement, and the clutch driving plate 71 and clutch driven plate 72 of clutch 7 are separated.In this case, the quilt of external toothing 52
It is locked on housing 1, the one degree of freedom in the three degree of freedom of planetary gears 5 is restrained, planetary gears 5 turns into
One single gear transmission device, its gearratio i=(Zr+Zs)/Zs, wherein, Zr is the number of teeth of external toothing 52, and Zs is sun gear
51 number of teeth.The output procedure of moment of torsion is specially：The moment of torsion that motor 9 is exported is transferred to output by planetary gears 5
Axle 3, the gearratio i of planetary gears 5 causes the speed of output shaft 3 to reduce moment of torsion increase, and specifically, motor 9 is exported
Moment of torsion is transferred to defeated through input shaft 2, sun gear 51, planetary gear 53, planet carrier 54 and input gear 41, output gear 42 successively
Shaft 3, is exported to the wheel of electric automobile eventually through power transmission mechanism (for example, differential mechanism).A gear is in speed changer
When, it is especially suitable for electric automobile and is in the state run at a low speed, the starting stage of such as automobile, or automobile in climbing, congestion
Etc. road conditions.
It will be readily appreciated by those skilled in the art that need to only change the direction of rotation of motor 9, in two gears with Fig. 2
On the premise of the power transmitting procedure of speed changer is essentially identical, you can realize the action of reversing gear of electric automobile.
As shown in figure 3, the figure shows the power transmitting procedure of electric automobile two shift transmissions in two gear states.This
When, the clutch driving plate 71 and the phase of clutch driven plate 72 of clutch 7 are caused in the presence of the hydraulic oil that oil pump 8 is exported
Engagement, and the brake driving disc spacing pressing 61 and brake clutch plate 62 of brake 6 are separated.In this case, the He of sun gear 51
Planet carrier 54 is locked into together, and the sun now can be derived according to the rotation speed relation of each part in planetary gears 5
Wheel 51, planet carrier 54 are identical with the rotating speed of external toothing 55, i.e., the gearratio of whole star gear mechanism 5 is 1.Motor 9 is exported
Moment of torsion after planetary gears 5, exported in the case of no reduction of speed to by 42 groups of input gear 41 and output gear
Into decelerator 4, and further power is exported to electronic vapour through power transmission mechanism (for example, differential mechanism) by output shaft 3
The wheel of car.When being in two gears in speed changer, be especially suitable for electric automobile and be in the state run at high speed, such as running car in
Substantially without the relatively small highway of traffic pressure or traffic pressure.
With further reference to Fig. 2 and Fig. 3, when electric automobile rises to two gears by a gear, clutch 7 is caused by oil pump 8
Master and slave Moving plate is gradually engaged, and at the same time the master and slave Moving plate of brake 6 is drifted apart from.Until the rotating speed of planet carrier 54
When consistent with the rotating speed of sun gear 51, the clutch 7 that master and slave Moving plate is fully engaged is by planet carrier 54 and the locking of sun gear 51, together
When brake 6 master and slave Moving plate also completely disengage from, automobile shifts to the gear shifting actions of two gears from a gear and is basically completed.Similarly, when two
The master and slave Moving plate that gear causes clutch 7 when being down to a gear, by oil pump 8 is progressively disengaged, at the same time cause brake 6 master,
Clutch plate is gradually combined, until the master and slave Moving plate of brake 6 is fully engaged, and brake 6 is by external toothing 55 and the locking of housing 1, together
When clutch 7 master and slave Moving plate also completely disengage from.The gear shifting action that automobile shifts to a gear from two gears is basically completed.
It will be readily appreciated by those skilled in the art that in shift process, due to each part of whole planetary gears 5
All in engagement, pass through the operational factor of control unit reasonably control oil pump 8 and valve group so that clutch 7 and brake
6 master and slave Moving plate smoothly can depart from or engage, so as to ensure that power of the electric automobile in shift process without in
It is disconnected, improve the dynamic property of automobile.The impact in shift process is simultaneously effective avoided, the comfortable of electric automobile is improved
Property.
So far, combined preferred embodiment shown in the drawings describes the technical solution of the utility model, still, this
Art personnel are it is easily understood that protection domain of the present utility model is expressly not limited to these embodiments.
On the premise of principle of the present utility model, those skilled in the art can make equivalent change to correlation technique feature
Or replace, the technical scheme after these are changed or replaced it is fallen within protection domain of the present utility model.
