Flow direction, flow through automobile primary drive system, tank for coolant, filter core, kinetic pump, wherein automobile primary drive system is by motor, speed change
Case, controller composition.The temperature feedback of automobile primary drive system is to Temperature Treatment analyzer, and Temperature Treatment analyzer-controller is on the one hand
The whole temperature rise situation for judging main drive system decides whether the circulation of input action signal to power pump controller adjustment coolant liquid
Speed；Still further aspect judges the respective temperature rise situation of three components of main drive system, decides whether input action signal to valve
Control unit adjusts the aperture of the first, second, and third control valve in every circulation branch road and then realizes the reasonable of coolant liquid
It shunts.Valve control unit, temperature analysis, branch road valve processor form closed loop one, power pump controller, temperature analysis processing
Device, kinetic pump formed closed loop two, closed loop first is that closed loop two subring.The present invention realizes in the main drive system of real time on-line monitoring
Temperature rise adjusts the circulation rate of coolant liquid according to the practical temperature rise situation of motor, gearbox, controller, and heat transfer effect is excellent, section
The about energy.
As shown in Figure 1, disclosing the mobility status that coolant liquid circulates in main drive system.From three tunnels of kinetic pump parallel connection point
Not Jin Ru main drive system, while in main drive system, motor and transmission gear are there are runner intercommunication, and coolant liquid is at transmission gear
Controller is flowed into after convergence, is flowing back into kinetic pump.
As shown in fig. 6, be more clear the case where disclosing main drive system function shell (as the control except shell in figure
System is not drawn), the liquid outlet of shell is connected with the inlet of controller, and thus figure is it can be seen that motor, transmission gear are set
In in same housing, thus the two may be implemented runner, coolant liquid it is shared, integrated level is more thorough, shares the scheme of shell
With compact-sized, the big advantage of system power/bulk density.And by the independent cooling system of three, being total to for runner is carried out
Enjoying realizes three-in-one integrated cooling.The coolant liquid that the present invention refers to is preferably oil.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
