In figure: 1, hydraulic efficiency pressure system, 2, electromagnetic valve, 3, fan assembly, 4, the empty check valve of anti-suction, 5, radiator panel, 6, propons, 7, fil group, 8, bridge oil suction pump group, 9, back axle.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises hydraulic efficiency pressure system 1, electromagnetic valve 2, fan assembly 3, the empty check valve 4 of anti-suction, radiator panel 5, bridge oil suction pump group 8, fil group 7, propons 6 and back axle 9.
Wherein: described hydraulic efficiency pressure system 1 is the hydraulic efficiency gear of car body, after electromagnetic valve 2, fan assembly 3 and anti-suction empty check valve 4 fuel feeding, then hydraulic efficiency pressure system 1 is flowed back to.
Described fan assembly 3 comprises fan with motor and by pass valve, and the oil return line of the empty check valve 4 of anti-suction flows into the motor of fan assembly 3.
The empty check valve 4 of described anti-suction is used for preventing fan motor from damaging, and during parking, fan is rotated further due to inertia, and the pump housing can not provide fluid, now motor can from oil return line again oil suction carry out the circulation of motor internal, prevent motor from inhaling empty;
Described electromagnetic valve 2 is bi-bit bi-pass normally closed valve, and wheel limit temperature sensor is electrically connected this electromagnetic valve 2 by controller, and carrys out the opening and closing of Controlling solenoid valve 2 according to the oil temperature detected.If the oil temperature that wheel limit temperature sensor detects is too low, as during lower than 70 DEG C, that is just opened by controller Controlling solenoid valve 3, makes part fluid get back to fuel tank, to ensure oil liquid temperature, also control the highest temperature of fluid by the hommization of temperature alarming switch simultaneously.
Described radiator panel 5 comprises propons radiator and back axle radiator, described bridge oil suction pump group 8 comprises propons oil suction pump and back axle oil suction pump, and propons 6, back axle 9 respectively by forward and backward bridge oil suction pump forward, after back axle radiator fuel feeding, flow back to propons 6, back axle 9 again, without the need to re-using heat radiation oil box, fluid is at pontic repeats itself.
Described fil group 7 comprises the front fil respectively carrying check valve, rear fil, described bridge oil suction pump group 8 comprises propons oil suction pump and back axle oil suction pump, bridge oil suction pump group 8 is respectively from propons 6, self oil suction of back axle 9, after the impurity of fil group 7 elimination fluid, oil is provided in radiator panel 5.If oil circuit pressure reaches check valve response pressure, then illustrate that forward and backward fil blocks, no longer directly entered in radiator panel 5 by corresponding check valve through forward and backward fil.
When using native system, fluid circulates in radiator panel 5, and by fan assembly 3 to its cooling, then gets back to respectively in propons 6, back axle 9.And the respective wheel limit of propons 6, back axle 9, master subtracts and the fluid of drg communicates, the element of cooled fluid to inside cools, and prepares to enter next circulation simultaneously.Whole drive axle cooling system is without the need to the valve group of fuel tank and complexity, and heat radiation oil is in drive axle inner loop, and oily leak point is few, and the reliability of complete machine increases.
