[0002] The steering oil pot of the car is used in the hydraulic power steering system of the car to store oil and provide the hydraulic steering system with working oil smoothly. The steering oil pot needs to be sealed. This design must have a venting hole design to ensure that the air sucked in by the back pressure formed by the oil inlet of the system is discharged; and a sealing design is required so that the oil cannot leak through the vent. Therefore, the steering oil pots currently used in the market have a single vent hole on the oil pot cover, mostly for ventilation function considerations, but lack a reasonable design structure. Even if leakage prevention is considered, the steering oil pot will either have poor ventilation effect or leak oil through the vent hole during use due to its structural design defects.

During the use of the steering oil pot, the aging of metal parts and rubber, and the failure of sealants will not only pollute the system oil and affect the service life of the steering oil, but also cause the failure of the seal, and the leakage of oil will bring other safety hazards or pollute the environment.

[0021] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings:

[0022] The utility model proposes a steering oil pot ventilation and sealing structure using a funnel-type oil pot cover, a multi-layer compass-type oil baffle plate and a multi-way labyrinth valve structure design. This patented design can well solve the problem of poor ventilation effect without oil leakage, as shown below Figure 2 .

[0023] This utility model patent designs a funnel-type steering oil pot cover 7 main structure, and integrates a multi-layer compass-type oil baffle plate and a multi-way labyrinth-type ventilation valve 8 structure, which effectively ensures the ventilation and sealing functions of the steering oil pot. Figure 2 .

[0024] The funnel-type steering oil pot cover 7 is shown in Figure 3 below. The inner center is designed to be a cone of appropriate size. The appropriate cone external structure 9 and cone height are determined according to the volume of the oil pot. The cone is designed with a through hole of appropriate size. This design can not only reduce the contact area of ​​the steering oil, prevent the oil level from tilting when the vehicle breaks the road and the high-temperature working oil level from rising, causing the oil to overflow from the through hole, but also discharge the gas formed by the high-temperature working of the oil. The inner structure 10 of the cone is matched with the multi-layer compass oil baffle plate and the multi-way labyrinth valve 8, and the depth size is combined with the height design of the multi-layer compass oil baffle plate. This structural design plays the first role in preventing the oil from overflowing.

[0025] The multi-layer compass oil baffle plate and multi-way labyrinth valve 8 are designed as shown in Figure 4 below. The bottom of this valve is designed to be a compass 11 of different sizes, which cooperates with the gap between the vertebral body of the funnel-shaped pot cover, allowing oil and gas to pass through the vent 12 smoothly, and forming a multi-layer umbrella-like barrier for the oil, which is the second further effective barrier for the oil. At this time, basically only gas can pass through. The top of the valve is designed to be a multi-way labyrinth 13 path of different heights, and vents 14 are opened in different directions of the labyrinth wall. The oil and gas can only be discharged to the atmosphere through the vents 14 of each labyrinth path, and after the working oil temperature drops, the very little condensed oil can also flow back to the oil pot through the labyrinth path.

[0026] The design scheme of the ventilation and anti-leakage sealing structure of the automobile steering oil pot integrates the funnel-type steering oil pot cover structure with the multi-layer compass-type oil baffle plate and the multi-way labyrinth valve assembly, and then adds a dust cover 15 to the ventilation hole, as shown below Figure 5 This design of sealing structure can give full play to the advantages of the structure, is easy to process and mold, has high quality and precision, and can give full play to the smooth exhaust of the structure design and effectively seal to prevent oil leakage.

[0027] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any person familiar with the technology can understand and think of any changes or substitutions within the technical scope disclosed by the present invention, which should be included in the scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
