A threeway is connected, and water tank, preceding driving motor and rear driving motor are connected by a threeway, cold in rear drive motor controller
But runner is connected with the coolant flow channel on rear driving motor, coolant flow channel correspondence and solenoid valve in preceding drive motor controller
And the coolant flow channel on preceding driving motor is connected.
A kind of cooling means of bi-motor 4 wheel driven pure electric coach cooling system, includes the following steps：
1) in vehicle operational process, when vehicle operation needed for torque be less than 300Nm when, at this time only after driving motor
Operating, if rear drive motor controller or the temperature of rear driving motor reach 40 DEG C or more, water pump and water tank start
Work, is reached for rear drive motor controller and rear driving motor is cooled down；
2) when required torque is greater than 300Nm, preceding driving motor participates in driving at this time, if preceding drive motor controller
Or the temperature of preceding driving motor when reaching 40 DEG C or more, then solenoid valve is opened, while water pump can improve revolving speed, increases flow,
With this come reach and meanwhile to preceding drive motor controller, preceding driving motor, rear drive motor controller, rear driving motor carry out it is cold
But effect.
The present invention has the advantages that：

Specific embodiment：
The present invention will be further described below with reference to the drawings.
As shown in Figure 1, a kind of bi-motor 4 wheel driven pure electric coach cooling system of the present invention, including water tank 1, deputy tank 2, three
Logical 3, water pump 4, solenoid valve 5, preceding drive motor controller 6, preceding driving motor 7, rear drive motor controller 8 and rear driving motor
9, cooling stream is equipped on preceding drive motor controller 6, preceding driving motor 7, rear drive motor controller 8 and rear driving motor 9
Road, water tank 1, deputy tank 2 and water pump 4 are connected by a threeway 3, and water pump 4, solenoid valve 5 and rear drive motor controller 8 pass through
One threeway 3 is connected, and water tank 1, preceding driving motor 7 and rear driving motor 9 are connected by a threeway 3, drives motor control afterwards
Coolant flow channel on device 8 is connected with the coolant flow channel on rear driving motor 9, the coolant flow channel in preceding drive motor controller 6
Correspondence is connected with the coolant flow channel on solenoid valve 5 and preceding driving motor 7.
Bi-motor four-wheel drive before and after the dynamical system of integral new-energy passenger equipped with subsystem is, it can be achieved that in due course 4 wheel driven, just
It is rear motor driven (torque needed for vehicle operation is when being less than 300Nm) in normal situation, before VCU can be controlled according to road conditions
Whether driving motor, which participates in, drives.According to the conventional method, the independent cooling system in two sets of front and back is needed, then needs two water tanks
Radiator, two water pumps.And in the present invention, forward and backward cooling line road is in parallel, an electromagnetism is added before preceding cooling line
Valve controls the on-off in water route, thus achievees the effect that cooling to preceding driving motor.The present invention is compared with traditional mode, it is only necessary to
One water tank, one water pump, greatly reduces manufacturing cost, while can reduce the energy consumption of vehicle again.
The cooling means of cooling system of the present invention, includes the following steps：
