[0002] With the rapid development of new energy non-road mining truck technology, the reliability requirements for motors are getting higher and higher, and all components of the motor should be able to meet the use environment and working conditions of non-road mining trucks. As an important component of the motor, the breather valve can balance the pressure inside and outside the motor cavity, prevent condensation, and allow breathing. Especially during the operation of an oil-cooled motor, the pressure inside its cavity will increase instantaneously due to the influence of oil and oil gas, and the role of the breather valve is particularly crucial. The breather valves of existing oil-cooled motors are generally directly assembled on the motor housing, and are easily blocked by external sediment and dust in the use environment of mining trucks, ultimately resulting in the breather valve being blocked and losing its function, further leading to various problems such as oil leakage from the oil seal of the oil-cooled motor, oil leakage at the plug-in part, and high temperature of the motor.

[0026] [First Embodiment]

[0027] As Figure 1 shown, a motor breather valve assembly provided by the first embodiment of the present invention includes a breather valve 10. The breather valve 10 in this embodiment is preferably a waterproof and oil-proof valve, which can not only balance the internal and external air pressures but also prevent the internal oil and gas from overflowing.

[0028] A housing 1 is installed outside the breather valve 10. In the form of the housing, the functions of anti-pollution, anti-salt spray, dust and sand prevention of the internal breather valve are enhanced, meeting the use requirements of the harsh external working conditions of non-road mining trucks and improving its service life.

[0029] One end of the housing 1 is connected to the motor housing through a gas guide pipe 2 and an adapter 3 to communicate with the internal cavity of the motor. As Figure 1 shown, the end of the gas guide pipe 2 connected to the motor housing is horizontally arranged, and the end of the gas guide pipe 2 connected to the housing 1 is vertically arranged. By guiding the gas upward, the functions of condensing oil and gas and preventing oil accumulation can be achieved, blocking a large amount of oil and gas from entering the breather valve and reducing the oil filtering load of the oil-cooled breather valve.

[0030] The other end of the housing 1 is connected to the atmosphere through a breather pipe 4, and the vent of the breather valve is led out through the breather pipe, improving the layout flexibility and anti-pollution function of the vent. One end of the breather pipe 4 is connected to the housing, and the other end is arranged at the inner groove position of the vehicle frame. By arranging the outlet of the breather pipe 4 at a position on the vehicle where mud and water are not likely to accumulate, the layout flexibility and anti-pollution function of the breather pipe 4 are improved.

[0031] As Figures 1-3 shown, the housing 1 includes a base 11 and a cover 12, and the cover 12 is fixed to the top of the base 11. By arranging the housing 1 to completely cover and wrap the breather valve 10, it plays a role in dust and sand prevention, avoiding the pollution challenge of the breather valve from the external environment, ensuring that the breather valve will not be blocked, and improving the service life of the breather valve.

[0032] As Figure 2 shown, the base 11 in this embodiment includes a base body 111 and a guide head 112 fixed to the bottom of the base body 111. The guide head 112 is connected to the air guide pipe 2, so that the gas inside the motor can enter the breather valve 10 through the adapter and the air guide pipe.

[0033] As Figure 3 shown, the cover 12 in this embodiment includes a cover body 121 and a joint 122 fixed to one side of the cover body 121. The joint 122 is connected to the breather pipe 4, and a breather valve external cavity 13 is formed between the top of the breather valve 10 and the cover 12. The breather valve external cavity 13 is connected to the atmosphere through the breather pipe 4, and interactive breathing with the atmosphere is realized through the breather pipe.

[0034] As a further preference, a base installation part 113 is provided at the outer edge of the top of the base body 111, and a cover installation part 123 is provided at the outer edge of the bottom of the cover body 121. The base installation part 113 and the cover installation part 123 are correspondingly installed and matched, and the base 11 and the cover 12 can be fixedly connected by fixing parts such as external screws or bolts passing through the base installation part 113 and the cover installation part 123.

[0035] The motor breather valve assembly provided in this embodiment can, while ensuring the functions of air permeability, waterproofness, and anti-oil leakage of the oil-cooled motor, also achieve dust prevention, sand prevention, and anti-salt spray under the operating conditions of non-road mining trucks, overall improving the reliability of motor operation.

[0036] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
