[ background of the invention ]
The operating principle of existing wet brake braking systems is to utilize the mutual friction between non-rotating elements connected to the vehicle body (or frame) and rotating elements connected to the wheels (or drive shaft) to resist rotation or the tendency of the wheels to rotate. A common non-rotating component is a brake shoe and the corresponding rotating component is a brake drum. When a driver steps on a brake pedal to enable the piston to compress brake fluid, the wheel cylinder piston presses the brake shoe to the brake drum under the action of hydraulic pressure, and the brake drum reduces the rotation speed or keeps the brake drum still. When the brake works, the temperature of the brake can be increased by heat generated by friction between the non-rotating element and the rotating element, the temperature of the brake can be continuously increased due to the closed brake oil cavity of the brake, and the braking performance can be attenuated when the temperature is too high, so that the driving safety is influenced, and the brake needs to be cooled to ensure the braking performance.
In the existing external circulation cooling system, a power source is taken from a main speed reducer of a drive axle, and a fan of an oil pump and a radiator is driven to work through the rotation of a gear of the main speed reducer, so that the flowing of an external circulation system and the cooling function of the radiator are realized. However, such prior art techniques have some disadvantages. Firstly, the power source of the external circulation system is taken from a main speed reducer of a drive axle, the rotating speed of the drive axle correspondingly changes along with the start-up and stop of the vehicle in the running process of the vehicle, and the external circulation system stops working in the state that the rotating speed of the drive axle is extremely low and stops, so that a brake cannot be continuously cooled; secondly, the fan of radiator is got power from transaxle final reduction gear, and the transaxle rotational speed constantly changes and makes the fan can not work under stable rotational speed, influences the cooling effect. Finally, in the prior art, power is taken from a main speed reducer gear of a drive axle, a transmission device needs to be added in an axle housing, the process is complex, and the cost is high.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention.

[ detailed description ] embodiments
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
As shown in fig. 1 and 2, the present invention provides an integrated wet brake external circulation cooling system, which includes an oil pump 3, a cooler 4, and a hydraulic motor 2. As shown in fig. 1 and 2, an inlet of the oil pump 3 is connected with the cooling oil storage through an oil pipe, and an outlet of the oil pump 3 is connected with an inlet of the cooler 4 through an oil pipe, so that the oil pump 3 can pump the oil in the cooling oil storage into the cooler 4 for cooling, and the temperature of the oil is reduced to the allowable temperature of the brake. The outlet of the cooler 4 is connected with the inlet of the cooling cavity 10 of the brake 9 through an oil pipe, and the outlet of the cooling cavity 10 of the brake 9 is connected with the cooling oil storage through an oil pipe, so that the components are connected in a closed loop, and are connected through pipelines. The oil liquid cooled by the cooler 4 enters the cooling cavity 10 of the brake 9 to cool the brake 9, and finally flows back to the cooling oil storage. The cooler 4 may include a cooling pipe and a cooling fan, and optionally, a motor of the cooling fan of the cooler 4 is directly powered by a vehicle-mounted power supply on the vehicle to operate, and the cooling fan can operate after the vehicle is powered on, and has a stable rotation speed and is not influenced by the vehicle running speed. The cooling pipe is spirally bent to be corrugated, and the cooling fan blows air to cool the cooling pipe, so that the oil is cooled. The motor of the cooling fan is connected with the vehicle-mounted power supply, and if the cooling fan adopts the electronic fan, the speed of the rotating speed of the fan can be adjusted along with the temperature of the brake, so that the temperature stability of the brake is ensured. Optionally, a filter 5 is arranged on an oil pipe connecting an inlet of the oil pump 3 with the cooling oil reservoir, and a filter 5 is also arranged on an oil pipe connecting an outlet of the cooling chamber 10 of the brake 9 with the cooling oil reservoir. A filter 5 is arranged in front of the cooler 4, so that impurities in the oil can be removed, the impurities are prevented from being brought into the cooler 4 by the oil, and a pipeline of the cooler cannot be blocked. And because the fluid in the stopper 9 is easy to be polluted by the impurity that the friction produced, so after fluid flows out from the cooling chamber 10 of stopper 9, return to the coolant oil accumulator after filter 5 filters earlier to guarantee the cleanliness of fluid in the coolant oil accumulator.
As further shown in fig. 1, the hydraulic motor 2 is connected to the oil pump 3 for driving the oil pump 3 to operate, so that oil circulates in the cooling system.

A gear pump 7 in the hydraulic brake system of the automobile pumps oil from an oil tank 6, and high-pressure oil enters a liquid filling valve 8 after passing through a filter 5. When the vehicle normally runs, high-pressure oil enters a brake cavity 11 of a brake 9 shown in fig. 2 through a normally-open working position of a pedal valve to finish the action of releasing the brake of the brake 9; the oil then flows back from the oil return of the charge valve 8 to the tank 6. When the vehicle brakes, the pedal valve is shifted to a working position corresponding to braking, a passage for high-pressure oil to enter a brake cavity 11 of the brake 9 is closed, and the high-pressure oil directly flows back to the oil tank 6 from an oil return port of the liquid filling valve 8. Therefore, when the automobile is in a starting state, oil flows back to the oil tank 6 from the return port of the liquid charging valve 8 in any working state of the automobile hydraulic brake system 1, and the oil can drive the hydraulic motor 2 to continuously work, so that the brake 9 is continuously cooled by the cooling system. Optionally, an inlet of the oil pump 3 is connected to an oil tank 6 in the hydraulic brake system 1 of the vehicle, so that the oil tank 6 in the hydraulic brake system 1 of the vehicle is used as a cooling oil reservoir, that is, the cooling system and the brake system share the same oil tank 6, thereby further simplifying the structure and making the structure more compact.

In order to meet the use condition of the brake 9, the maximum pressure of the integrated wet brake external circulation cooling system in the cooling cavity 10 of the brake 9 is not more than 0.2MPa, because the oil directly enters the oil tank 6 after flowing out of the cooling cavity 10, the oil tank 6 is communicated with the atmosphere, the backpressure of the oil in the cooling cavity 10 is 0.1MPa, the back end pipeline is considered to be short, the pressure loss is negligible, and therefore the backpressure of the oil in the cooling cavity 10 is not more than 0.2MPa, and the use condition of the brake 9 can be met. The thermal power of a cooler 4 adopted by the brake external circulation cooling system can be 10-15KW, namely, when the maximum flow does not exceed 200L/min, the temperature of the oil can be reduced to exceed 40 ℃. The displacement of an oil pump 3 adopted by the external circulation cooling system of the brake is 20ml/r, a power source is a hydraulic motor 2, the hydraulic motor 2 is driven by return oil of the hydraulic braking system 1 of the automobile, and the rotating speed is usually not more than 4000r/min, so the maximum flow of the external circulation cooling system of the brake is not more than 80L, and the power of the hydraulic motor 2 can meet the maximum flow requirement of a cooler 4.
