Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in figure 1, a kind of loading machine fans drive liquid with auxiliary braking and hydraulic oil heating function of the utility model
Pressure system, including hydraulic oil container 1, automatically controlled Variable plunger pump 2, ECU control box 3, solenoid directional control valve 4, temperature sensor 5, gear
Motor 6, radiator 7 and brakes 8；The automatically controlled oil inlet of Variable plunger pump 2 is connected with hydraulic oil container 1, and oil-out is changed with electromagnetism
It is connected to the P mouths of valve 4；The A hydraulic fluid ports of solenoid directional control valve 4 are connected with the oil inlet of gear motor 6, the oil-out of gear motor 6 with
The oil inlet of radiator 7 is connected, and the leakage hydraulic fluid port L that gear turns motor 6 is connected with hydraulic oil container 1；The oil-out of the radiator 7 with
Hydraulic oil container 1 is connected；ECU control box 3 by wire harness respectively with temperature sensor 5, solenoid directional control valve 4, automatically controlled Variable plunger pump 2
It is connected with brakes 8.The utility model provides a kind of mounting means of automatically controlled variable pump 2, and automatically controlled variable pump 2 is directly installed in
On engine.
Wherein the output of ECU control box 3 electric signal controls the automatically controlled discharge capacity of Variable plunger pump 2 to control rotation speed of the fan, to realize
Can only function of temperature control.The output electric signal control spool position of solenoid directional control valve 4 of ECU control box 3, to realize that hydraulic oil is quickly heated
Function and auxiliary brake function.
Operation principle of the present utility model is as follows：After loading machine starts, the meeting collecting temperature of ECU control box 3 sensor 5
Signal, and automatically controlled Variable plunger pump 2 is outputed it to, when the temperature of hydraulic oil is relatively low, ECU control box 3 can export an electricity
Stream makes automatically controlled Variable plunger pump 2 be in small displacement, and gear motor 6 and fan are operated with relatively low rotating speed；With loading
The increase of machine working time, hydraulic fluid temperature rises, and now ECU control box 3 goes out signal to automatically controlled Variable plunger pump 2, arranges it
Amount increase, exports the flow increase to gear motor 6, and rotation speed of the fan increase realizes medium temperature rise, rotation speed of the fan increase
Intelligent temperature control function；Conversely, the discharge capacity of automatically controlled Variable plunger pump 2 reduces, rotation speed of the fan declines.
When the temperature of hydraulic oil is less than 15 DEG C, ECU control box 3 can output signal to solenoid directional control valve 4, make its commutation extremely
Zuo Wei, allows hydraulic oil to flow to gear motor 6 by choke valve, while ECU control box 3 outputs signal to automatically controlled Variable plunger pump 2,
Increase its discharge capacity, now whole system makes its pressure rise because of the presence of choke valve, hydraulic oil temperature is increased rapidly.When
When oil temperature rises to 50 DEG C, ECU control box 3 can stop the output of the current signal of solenoid directional control valve 4, make its valve element in the effect of spring
Under be back to right position, terminate hydraulic oil heating function.
When driver's brake pedal, brakes 8 can transmit signals to ECU control box 3, ECU control box meetings
Signal transmission makes its valve element commutate to left position to solenoid directional control valve 4.ECU control box 3 outputs signal to automatically controlled variable piston simultaneously
Pump 2, increases its discharge capacity.Now pump output is the moment of torsion that now automatically controlled Variable plunger pump 2 needs in high-pressure high-flow hydraulic oil
Increase, is braked by it to engine.To reach the purpose of auxiliary braking.
The utility model above three function, its priority is that auxiliary brake function is optimal, hydraulic oil rapid heating function
Take second place, intelligent temperature control function is basic function.
Certainly, above-described embodiment is only preferred scheme of the present utility model, is specifically not limited thereto, and on this basis may be used
Make according to actual needs with targetedly adjusting, so as to obtain different embodiments.Due to mode in the cards compared with
It is many, just no longer illustrate one by one here.
