As shown in Figure 1, the hydraulic cooling system of a kind of electric power wheel self-discharging vehicle that the utility model provides comprises fuel tank 100, the hydraulic oil of the control system of dumping car passes back into fuel tank 100, namely the hydraulic oil of the oil return circuit of each executive component of dumping car passes back into fuel tank 100, and stored by fuel tank 100 and circulate and feed to each executive component, the control system of dumping car refers to the other system being different from cooling system.
This hydraulic cooling system also comprises cooler and oil pump, in-line 200 and oil circuit 300 is connected between this cooler and fuel tank 100, in-line 200 refers to the oil circuit from fuel tank 100 to cooler fuel feeding, oil circuit 300 refers to the oil circuit from cooler to fuel tank 100 oil return, correspondingly, oil pump is arranged on in-line 200, by the hydraulic-pressure pump of fuel tank 100 to cooler.
Cooler as herein described refers to have radiating component, as coiler, fin, Heat sink etc., thus can increase a kind equipment of the area of contact of internal hydraulic pressure oil and outside air, this kind equipment commercially more easily obtains, further, optional model is more, and cost is lower.
Visible, the utility model provides a kind of hydraulic cooling system independent of control system, and namely hydraulic cooling system is not controlled systematic influence, and relative to control system, this belongs to external circulating system, and this hydraulic cooling system has the following advantages:
The first, hydraulic cooling system is set specially, adopts the mode of outer installment cooler, thus increase the area of contact of hydraulic oil and external environment condition, obtain better radiating effect, the defect low with the radiating efficiency overcoming existing dumping car, oil temperature is high;
The second, hydraulic cooling system directly gets oil from fuel tank 100, and independent of control system, the oil mass change of the oil return circuit of control system does not impact hydraulic cooling system, ensures that cooling system has stable, reliable cooling performance.
Further, the hydraulic cooling system of electric power wheel self-discharging vehicle also comprises the filter 103 be connected on the oil circuit of cooler, filter 103 is a kind of mini-plants can removing a small amount of solid particle in hydraulic oil, particulate pollutant by filtering in filter 103, thus avoid particulate matter to enter fuel tank 100 in the cool cycles of hydraulic oil, the confession luboil cleanness of Guarantee control system, improves the whole work efficiency of dumping car.
Further, above-mentioned filter 103 can be arranged on the in-line 200 of cooler, hydraulic oil pumps from fuel tank 100, entering before cooler cools, first enter filter 103 to filter out impurities, like this, the impurity in hydraulic oil is just retained in filter 103, and can not enter cooler.
Not bery high due to the bearing capacity of cooler self, and impurity enters filter and will form resistance, therefore filter is arranged on cooler in-line instead of is arranged on cooler oil circuit to avoid forming elevated pressures in cooler.
Can also following examples be had:
The fuel tank 100 of hydraulic cooling system comprises steering oil vessel and lifting fuel tank, the in-line 200 of cooler comprises the first oil circuit 201 and the second oil circuit 202, oil pump comprises the first oil pump 1041 and the second oil pump 1042, first oil pump 1041 and the second oil pump 1042 and is located at respectively on described first oil circuit 201 and the second oil circuit 202.
Steering system, namely controls the hydraulic system of working of the executive component of dumping car go to action, to steering oil vessel oil return; Hoisting system, namely control the hydraulic system of working of the executive component of Tipper Lifting action, to lifting tank drainback, steering oil vessel and lifting fuel tank are integrated in a total fuel tank 100.
Between steering oil vessel and cooler, and between lifting fuel tank and cooler, be connected to the first oil circuit 201 and the second oil circuit 202 respectively.Hydraulic oil in steering oil vessel and lifting fuel tank flows to cooler by the first oil pump 1041 through the first oil circuit 201 respectively, flows to cooler by the second oil pump 1042 through the second oil circuit 202.
The steering system of dumping car and hoisting system are most important two control system, the hydraulic oil demand of these two control system is large, circulation fast, and, higher to the quality requirements of hydraulic oil, therefore, these two systems are all carried out to the method for external cooling system, effectively can improve working efficiency and the workmanship of dumping car.
Further, cooler can also have two, namely comprises the first cooler 101 and the second cooler 102, first cooler 101 is connected on the first oil circuit 201, second cooler 102 is connected on the second oil circuit 202, and two coolers are connected to respective oil circuit 300 respectively.
Like this, hoisting system, steering system have respective cooling subsystem, by respective cooler cooling liquid force feed, further improve cooling effectiveness.
Certainly, steering oil vessel and lifting fuel tank also can be made to share a cooler, just, by contrast, the cooling effectiveness of this mode is inevitable lower.
Further, this hydraulic cooling system can also comprise filter 103, and this filter 103 is only arranged on and is connected on the first oil circuit 201 of steering oil vessel, with the impurity in filtering hydraulic oil.
Steering pump is that plunger pump is high to cleanliness of hydraulic oil requirement, therefore, arranges filter 103 in the present embodiment at the first oil circuit 201.
Certainly, also can be equipped with filter 103 at the first oil circuit 201 of the second oil circuit 202 of lifting fuel tank and steering oil vessel, just may cause the wasting of resources.
In the respective embodiments described above, the oil pump be connected on in-line 200 can be gear pump.
