Description
Technical Field
The utility model relates to the technical field of new energy automobile driving unit valves, in particular to a novel waterproof oil-filtering ventilation valve for a new energy automobile driving unit.
Background
The driving unit of the new energy automobile usually adopts lubricating oil to lubricate the temperature of parts such as gears and bearings, cooling the surfaces of the gears, bearings, stator and rotor and the like, thereby ensuring the performance and functions of the system. When the driving unit operates, heat is necessarily generated by rotation of the motor stator/rotor, the gear, the bearing and the like, the air pressure of the cavity in the system is increased, the real-time balance between the cavity pressure and the external atmospheric pressure is required to be maintained through the air-permeable valve, otherwise, a sealing system (such as an oil seal, a plug and the like) of the driving unit faces challenges, leakage occurs in severe cases, and the performance and the service life of the driving unit are endangered. The gas components generated inside the drive unit are relatively complex and mainly include air (O2, N2, etc.) molecules (0.0004 μm in size), water vapor molecules (0.0004 μm in size), and aerosols generated by the operation of parts and stirring of lubricating oil, and the particle size thereof is generally between 0.1 and 100 μm. The detection of the aerosol generated by the new energy driving unit has three main characteristics: high concentration (tens of millions/liter), low flow (typically less than 1L/min), small particle size (most particles less than 1 μm).
The waterproof and breathable valve structure described in the Chinese patent publication No. CN214425204U can only rely on a spiral channel formed by a spiral column to prevent the pollution of the waterproof and breathable film caused by the direct impact of liquid oil in the cavity, but cannot prevent the pollution of the waterproof and breathable film caused by the increase of the pressure of the oil aerosol along with the cavity and the removal of gas. Further, in the patent of publication No. CN107289165A and the patent of CN207049387U, the so-called "filter block is provided with a plurality of filter holes, which can block most of the oil molecules from entering the through air holes without blocking the circulation of gas", the construction of the filter medium scheme is not described in detail, and the effect of blocking the oil aerosol molecules is not provided, and the detection means of the effect of blocking the oil aerosol is not provided, so that it cannot be described that it has a function of efficiently intercepting the oil aerosol. Further, in the CN110345287a patent and the CN211779237U patent, the so-called filtering polymer fiber material has a good oleophobic and breathable effect, but the filtering effect, the test method and the like are not further described in the patent, so that the filtering polymer fiber material cannot be described as having a function of effectively intercepting the aerosol. In summary, the waterproof ventilation valve described in the prior patent can either rely on a labyrinth structure design to prevent certain oil from splashing, but cannot filter the aerosol, or claims to have certain aerosol filtering capability but no effective detection means to prove the filtering capability.
