Abstract
The invention discloses a drive axle cooling system, in particular to a novel 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.

Technical field
The present invention relates to the drive axle cooling system, be specifically related to a kind of novel hydraulic system of drive axle cooling system.
Background technology
In construction machinery and equipment as the drive axle of loader, road grader, roller etc., can produce a large amount of heat in the working process of machinery, part and lubricating oil temperature in the drive axle are constantly raise, lubricating oil is at high temperature apt to deteriorate for a long time, performance descends, and parts such as gear also damage easily.
On drive axle heat-dissipation problem, people have also found out a lot of ways, but always undesirable, or radiating effect is not good, or do not have automatically to detect the oil temperature and increased a large amount of equipment besides and make machinery integral too huge.Wherein the application number that proposed on March 9th, 2006 is that the utility model " construction machinery and equipment driving heat abstractor " of CN200620033361.7 is that present radiating effect is relatively good, also can detect the device of oil temperature automatically, comprise drive axle, radiator, the oil suction pipe that is communicated with drive axle and radiator, oil return pipe, be arranged on oil pump and an end and oil pump bonded assembly transmission shaft on the oil suction pipe, its principal character is that the transmission shaft other end is provided with the magnetic clutch that is mated, this magnetic clutch is connected with engine installation through driving band, be to utilize temperature sensor to detect the switching that oily temperature is controlled magnetic clutch, make cooling system work, realize heat sinking function.But this system has increased equipment such as radiator, driving band more, has increased machinery integral volume and the cost on making.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, and a kind of novel hydraulic system of drive axle cooling system is provided, and solves the problem that the drive axle cooling system that uses at present can not satisfy radiating effect, automatic guidance simultaneously and not increase equipment.
For solving above-mentioned technical matters, the present invention by the following technical solutions:
A kind of novel hydraulic system of drive axle cooling system is provided, and this system is become by full power hydraulic brake system, three groups of subsystems of drive axle radiator liquid pressing system and fan radiator liquid pressing system:
Wherein all-hydraulic is that brake system is formed and is connected successively with driving rear axle by hydraulic reservoir, brake pump, prefill valve, driving energy storage, hand brake valve, foot brake valve, service brake switch, driving propons; Drive axle radiator liquid pressing system comprises electromagnetic relief valve, drives propons, driving rear axle, temperature sensor, filter, cooling vessel, motor-pump assembly and filter; Fan radiator liquid pressing system is formed and is connected successively by hydraulic reservoir, pump, hydraulic fan assembly, radiator and cooling vessel.
All-hydraulic is in the brake system prefill valve to be preset pressure and topping up speed range value, and when topping up reached this scope, commutation was to the electromagnetic relief valve fuel feeding in the drive axle cooling system.
Be arranged on the temperature sensor control electromagnetic relief valve in the drive axle in the drive axle radiator liquid pressing system, lubricating oil temperature just often in drive axle, hydraulic oil is directly got back to hydraulic reservoir through electromagnetic relief valve, when lubricating oil temperature is too high in the drive axle, electromagnetic valve dead electricity in the electromagnetic relief valve, hydraulic oil process and the motor that drives in motor-pump assembly return hydraulic reservoir, motor drives the pump rotation in motor-pump assembly, the lubricating oil that drives in propons and the driving rear axle is got back in driving propons and the driving rear axle after the cooling vessel cooling through motor-pump assembly, finished cooling lubricating oil;
In drive axle heat radiation hydraulic work system, fan radiator liquid pressing system is also worked simultaneously, and pump sucks hydraulic oil in the radiator from hydraulic reservoir, enters cooling vessel after the cooling of hydraulic fan assembly radiating, finishes the cooling to hydraulic oil.
For better reaching the invention effect:
The temperature that described temperature sensor is set is 70 ℃.
Described temperature sensor has one, is used for detecting the temperature of the lubricating oil that drives propons, and motor-pump assembly has two pumps, respectively the gear lubricant in controlling and driving propons and the driving rear axle.
Compared with prior art, the invention has the beneficial effects as follows:
1. owing to there is fan radiator liquid pressing system that the hydraulic oil in the hydraulic reservoir is cooled off, to carry out the hydraulic fluid temperature of interchange of heat relative on the low side with lubricating oil in cooling vessel, and effectiveness of regenerator is big, and radiating effect then of the present invention is splendid.
2. the temperature detection of temperature sensor to the lubricating oil in the drive axle arranged, of the present inventionly start working and quit work, do not need manual operation fully, reached the automatic guidance effect thereby control.
With transfer of heat in hydraulic oil, utilize the heat abstractor heat radiation of hydraulic pressure cooling system, unified heat radiation, thereby be issued to the heat-dissipation effect in the situation that does not increase equipment.
