Embodiment Construction
[0019] Below in conjunction with accompanying drawing, the present invention will be further elaborated, in conjunction with figure 1 Schematic shown:
[0020] combine figure 1 The schematic diagram shown is a hydraulic system of the driving axle cooling system, which is composed of three subsystems: the full hydraulic braking system, the driving axle cooling system and the fan cooling hydraulic system:
[0021] The full hydraulic braking system consists of a hydraulic oil tank 1, a brake pump 2, a filling valve 4, a driving accumulator 6, a hand brake valve 7, a foot brake valve 8, a driving brake switch 9, and a drive front axle 10 and The drive rear axle 12 is formed and connected in sequence; the drive axle cooling system includes an electromagnetic overflow valve 5, a drive front axle 10, a drive rear axle 12, a temperature sensor 11, a first filter 13, a cooler 14, a motor-pump assembly 17 and The second filter 3; the cooling fan The hydraulic system is composed of a h...

The invention discloses a drive axle cooling system, in particular to a hydraulic system of a drive axle cooling system, which is characterized in that the system comprises three sub-systems, i.e. a full-hydraulic brake system, a drive axle cooling hydraulic system and a fan cooling hydraulic system. The system has the benefits that because the fan cooling hydraulic system cools the hydraulic oil in a hydraulic oil tank, the temperature of the hydraulic oil in a cooler which exchanges heat with lubricating oil is relatively lower, the heat exchange rate is high, and the cooling effect of the system is very good. A temperature sensor detects the temperature of the lubricating oil in a drive axle, so as to control the start and the stop of the system without manual operation, and achieve the automatic control effect. Heat is transferred to the hydraulic oil, a cooling device of a hydraulic cooling system cools in a unified way, so as to achieve the cooling effect under the condition of not adding equipment.
Description
technical field [0001] The invention relates to a driving axle cooling system, in particular to a hydraulic system of the driving axle cooling system. Background technique [0002] Drive axles in construction machinery such as loaders, motor graders, road rollers, etc. will generate a lot of heat during the working process of the machinery, which will make the parts and lubricating oil in the drive axle continue to rise in temperature, and the lubricating oil will easily Deterioration, performance decline, and parts such as gears are also easily damaged. [0003] On the problem of drive axle heat dissipation, people have also come up with many solutions, but they are always unsatisfactory, or the heat dissipation effect is not good, or there is no automatic detection of oil temperature, or a large number of equipment is added to cause the machine to be too large. Among them, the utility model "construction machinery drive cooling device" with the application number CN200620...
