Embodiment
One embodiment of motor-gearbox dynamic unit is as shown in Fig. 2 ~ Fig. 4, including gearbox 10, motor 11
And the end cap 6 between gearbox 10 and motor 11 is arranged on, motor 11, which includes being provided with casing 9, casing 9, to be determined
Sub- iron core 8 and rotor assembly 7, motor shaft 1, which runs through on motor 11 and end cap 6, end cap 6, to be provided with for supporting motor shaft 1
Bearing 3.The lubricating system of gearbox 10 is splash lubrication, the i.e. gear by being sealed in gear box 4（Do not show in figure
Go out）, gear box oil 5 is spilt from oil droplet by gear ratio larger rotary speed to be atomized into droplet and take to be formed on friction pair and moistened
It is sliding.In order to prevent that gear box oil 5 from being penetrated into inside motor 11 by the gap between motor shaft 1 and end cap 6, in end cap 6
Upper setting oil sealing 2 does encapsulation process come the interface to motor 11 and gearbox 10, this part-structure and prior art
In motor-gearbox dynamic unit be identical.
In addition, motor-gearbox dynamic unit also include connecting inside one end and motor 11, the other end and change
The oil return circuit of the inside of fast case 10 connection, the oil return circuit is by being opened in the casing 9, end cap 6 and gearbox of motor
Casing 4 in the oil duct 14 of connection formed, oil duct 14 is included positioned at casing 9 and the cathetus oil duct part of casing 4, positioned at end cap
N shape oil ducts part in 6.
Wherein, the connection end connected with the inside of gearbox 10 of oil duct 14 is connected with oil pump 12, so when in gearbox 10
Gear box oil 5 when penetrating into the inside of motor 11 and reaching certain aggregate amount, it is possible to open oil pump 12, the work of oil pump 12
When making, the interface of oil duct 14 and oil pump 12 produces negative pressure, so as to so as to be flowed back into the gear box oil in motor 11
To inside gearbox 10.Meanwhile, the height of n shape oil ducts part is more than the liquid level of gear box oil 5, so when the not work of oil pump 12
When making, gear box oil 5 will not be entered inside motor 11 by oil duct 14.
The recess groove directed downwardly through each stator punching is offered on stator core 8, the groove is dovetail groove
13, one end connected with the inside of motor 11 of oil duct 14 is arranged towards dovetail groove 13, when gear box oil 5 enters motor
Behind 11 inside, the bottom of casing 9 can be deposited to, or the bottom of casing 9 is fallen on along under each stator punching following current, these
Fluid can be flowed into oil duct 14 along dovetail groove 13, and is back in the presence of oil pump 12 inside gearbox 10, so as to protect
Demonstrate,prove the insulating properties of motor 11, it is to avoid the operational failure of motor 11.
Why the dovetail groove 13 that runs through is opened up on stator core 8, and it between stator core 8 and casing 9 is tight to be due to
What contiguity was touched, if only one of which oil-passage inlet, positioned at the change of the left side of stator core 8 or right side area in casing 9
Fast case oil can not be just back in oil duct 14, while the fluid that following current is fallen on each stator punching can not also be back to oil duct
In 14, therefore dovetail groove 13 is opened up in the bottom of stator core 8, with regard to solving this problem well, otherwise can only just set
Multiple arrival ends, the structure of such oil duct just becomes sufficiently complex.
Another embodiment of motor-gearbox dynamic unit is as shown in figure 5, the knot of the motor-gearbox dynamic unit
Structure is identical with the structure in above-described embodiment, only difference is that, oil return circuit is not by being opened in motor
The oil duct of connection in the casing of casing, end cap and gearbox is formed, but by being arranged on outside motor-gearbox dynamic unit
The return line 15 in portion is constituted, and one end of return line 15 is connected with the inside of motor 11, inside the other end and gearbox 10
Connection, is at this moment again provided with oil pump, stator core equally offering dovetail groove in gearbox 10.
In the other embodiment of motor-gearbox dynamic unit：Oil duct can be linear oil duct, and now oil pump is needed
Want normally opened to prevent that gear box oil is back in motor；Groove on stator core can also be rectangular channel；Stator core
On can not open up groove, can now open up groove on electric machine casing, or be located on casing the both sides of stator core
It is respectively provided with oil-passage inlet.
The implementation of dynamical system is for example shown in Fig. 2 ~ Fig. 5, dynamical system include motor-gearbox dynamic unit and with it is described
The connected transmission device of motor-gearbox dynamic unit（Not shown in figure）, the other end of transmission device is connected with wheel, electric
The concrete structure of machine-gearbox dynamic unit is identical with the structure in above-mentioned motor-gearbox dynamic unit embodiment, herein not
It is described in detail again.
The implementation of automobile is for example shown in Fig. 2 ~ Fig. 5, and the automobile is a kind of pure electric automobile, including vehicle frame（Not shown in figure）
With the dynamical system being arranged on vehicle frame, dynamical system includes motor-gearbox dynamic unit and dynamic with the motor-gearbox
The connected transmission device of power unit（Not shown in figure）, the other end of transmission device is connected with wheel, motor-gearbox dynamic list
