Description

Technical Field

[0001] The utility model belongs to the technical field of automobiles, and in particular relates to a structure for eliminating the regulating sound of a distribution valve of an air suspension vehicle and a vehicle. Background Art

[0002] The air distribution valve plays a vital role in the delicate process of height adjustment of air-suspension vehicles. When the vehicle needs to adjust its height according to road conditions or the needs of the driver, the air distribution valve responds quickly and accurately, and finely distributes and adjusts the air path by controlling the opening and closing of the valve port. In this process, the opening and closing of the valve port is not silent. As the valve port opens, high-pressure air flows through the narrow channel, producing a unique air flow sound. When the valve port closes, the air is quickly cut off, and this rapid change in air pressure also produces a short impact sound. Although these sounds seem insignificant in the context of mechanical operation, they will still be transmitted along the air path, the body structure, and finally into the vehicle's cabin.

[0003] Conventional air suspension vehicles are often faced with the challenge of eliminating the sound of air supply unit adjustment when designing, see Figure 1 Specifically, when the air supply unit receives the adjustment instruction, the valve port of the distribution valve will open and close. The mechanical vibration generated by this action will be directly transmitted to the vehicle body through the distribution valve bracket and the air supply unit main bracket. Since almost all of these connection parts are hard-connected and there are no effective buffering and shock-absorbing measures, the vibration can easily be transmitted to the driver's cabin. The driver and passengers will clearly feel this vibration in the car, which not only affects the ride comfort, but also may lead to a significant decline in the driving experience. Especially on bumpy roads or when driving at high speeds, this problem is particularly prominent, and the driver and passengers may feel uncomfortable or even irritated. Therefore, for traditional air suspension vehicles, how to effectively reduce the vibration and noise generated by the adjustment of the air supply unit has become one of the key issues to improve the user experience.

[0004] In summary, the noise of the distribution valve not only affects the driving and riding experience, but may also cause damage to the vehicle itself and related equipment, and even increase energy consumption. Therefore, during the design and manufacturing process, measures should be taken to reduce the noise level of the distribution valve as much as possible. Utility Model Content

[0034] The utility model is further described in detail below with reference to the accompanying drawings:

[0035] Example

[0036] As mentioned in the background technology, there are some problems in adjusting the distribution valve of air suspension vehicles at present, such as: the mechanical parts inside the distribution valve generate friction during the adjustment process due to insufficient lubrication, aging or wear of parts, failure of the shock absorber or wear of the internal parts of the shock absorber resulting in weakened damping effect, aging, damage or improper installation of the seals of the distribution valve, resulting in gas leakage. These problems will cause the air suspension vehicle to generate noise when the distribution valve is adjusted, affecting the driving experience of the passengers in the vehicle, so it is necessary to find a new structure to solve this problem.

[0037] In order to solve the above technical problems, the embodiment of the utility model proposes a structure for eliminating the adjustment sound of a distribution valve of an air suspension vehicle and a vehicle.

[0038] like Figure 2 As shown, this embodiment provides a structure for eliminating the adjustment sound of the distribution valve of an air suspension vehicle, including a suspension 5, wherein the suspension 5 is located at two symmetrical points on the side of the distribution valve 1. By arranging the suspension 5 at two symmetrical points on the side of the distribution valve 1, it can be ensured that the vibration to which the distribution valve 1 is subjected during the driving of the vehicle is significantly reduced, thereby improving its working performance. The design of the suspension 5 can enable the distribution valve 1 to maintain a relatively stable position during the driving of the vehicle, thereby reducing the position deviation caused by vehicle bumps or acceleration / deceleration.

[0039] In this embodiment, the distribution valve 1 is located on the distribution valve bracket 2, and gaskets 7 are arranged on both symmetrical sides of the line connecting the bottom surface of the distribution valve 1 and the suspension 5. The gasket 7 can fill the small gap between the two contact surfaces to form a sealing layer to prevent gas or liquid leakage. In the distribution valve of the air suspension vehicle, the gasket 7 ensures the sealing between the bottom surface of the distribution valve 1 and the suspension 5, ensuring the normal operation of the air suspension system.

[0040] In this embodiment, Figure 3 As shown, the number of the suspensions 5 is two.

[0041] In this embodiment, a suspension core 6 is disposed inside the suspension 5 , and the number of the suspension core 6 is the same as the number of the suspensions 5 .

[0042] In this embodiment, Figure 4 As shown, the gasket 7 includes a first gasket 7 - 1 and a second gasket 7 - 2 , wherein the first gasket 7 - 1 is located on two symmetrical sides of the suspension 5 connection line, and the second gasket 7 - 2 is located on the bottom surface of the distribution valve 1 .

[0043] In this embodiment, the number of the first gaskets 7 - 1 and the number of the second gaskets 7 - 2 are the same.

[0044] The present invention is further explained below in conjunction with a group of examples and drawings:

[0045] like Figure 2 and Figure 3 As shown, suspensions 5 are arranged at two symmetrical points on the side of the distribution valve 1, and the number of the suspensions 5 is 2. A suspension inner core 6 is arranged inside each of the two suspensions 5. The suspension inner core 6 is used to support and fix the entire suspension system. The suspension inner core 6 can play a good guiding and rough positioning role. Through the suspension inner core 6, the distribution valve 1 and other components can be flexibly connected to the frame or chassis to achieve the effect of vibration reduction and vibration isolation.

[0046] Another example Figure 2 As shown, two suspensions 5, two suspension cores 6, four gaskets 7 and a distribution valve 1 together constitute a suspension system, and the suspension system is arranged on the main support 3 of the air supply unit.

[0047] like Figure 4As shown, gaskets 7 are arranged on both symmetrical sides of the bottom surface of the distributing valve 1 and the line connecting the suspension 5, and the gaskets 7 include a first gasket 7-1 and a second gasket 7-2, wherein the first gasket 7-1 is located on both symmetrical sides of the line connecting the suspension 5, and the second gasket 7-2 is located on the bottom surface of the distributing valve 1, the number of the first gaskets 7-1 is 2, and the number of the second gaskets 7-2 is 2.

[0048] Another example Figure 4 As shown, the gasket 7 is a rubber gasket that can absorb and reduce vibration and impact.

[0049] In summary, this embodiment provides a structure with a simple structure for eliminating the adjustment sound of the distribution valve of an air suspension vehicle, which can not only effectively reduce the generation and transmission of noise, but also significantly reduce the vibration transmission from the distribution valve 1 through the carefully designed suspension 5 and gasket 7, thereby reducing the noise generated thereby and providing passengers with a quieter and smoother riding experience.

[0050] The present embodiment also provides an air suspension vehicle that eliminates the sound of distribution valve adjustment. The vehicle adopts a structure of an air suspension vehicle that eliminates the sound of distribution valve adjustment, which can effectively reduce the generation and transmission of noise when the distribution valve is adjusted. The vehicle that adopts an air suspension system to eliminate the sound of distribution valve adjustment has obvious advantages in improving driving comfort, reducing noise, enhancing vehicle stability, extending component life and increasing vehicle value.

[0051] Working principle:

[0052] In the process of height adjustment of the air suspension vehicle of the utility model, in order to eliminate noise, a suspension system is added, and the suspension system includes two suspension 5 structures, which are respectively located at symmetrical points on the side of the distribution valve 1, and are used to provide stable support during the driving process of the vehicle. In addition, two suspension cores 6 are equipped inside each suspension 5 to ensure that sufficient damping effect can be provided when subjected to vibrations in different directions.

[0053] In order to further enhance the vibration isolation capability of the system, a high-performance rubber gasket 7 is designed on both symmetrical sides of the suspension 5 structure connection line. These gaskets 7 not only have good elasticity, but also can effectively absorb and disperse vibration energy, thereby greatly reducing the generation and transmission of noise when the distribution valve 1 is working. In particular, when the valve port of the distribution valve 1 is opened and closed, the suspension 5 and the gasket 7 work together to prevent the vibration from being transmitted to the vehicle body 4 through the distribution valve bracket 2 and the air supply unit main bracket 3, thereby forming an efficient vibration isolation barrier and effectively blocking the propagation path of the sound.

[0054] At the same time, considering that the vehicle may encounter bumps during driving, two rubber gaskets 7 are added under the distribution valve 1. These two gaskets 7 can not only provide additional support in the Z direction to enhance the stability of the suspension system, but also further absorb and disperse vibration energy when the vehicle bumps, thereby protecting the distribution valve 1 and the entire suspension system from damage. This design not only improves the durability of the system, but also extends the service life of the suspension system and the distribution valve 1.

[0055] In general, this suspension system can maintain perfect isolation between the distribution valve 1 and the entire vehicle under various working conditions, and its vibration isolation effect is significant and lasting no matter what state the vehicle is in. More importantly, the added suspension 5 and gasket 7 are both lightweight in design, with a small size and moderate weight, which has little impact on the overall weight and manufacturing cost of the vehicle. This cost-effective design not only improves the comfort and quietness of the vehicle, but also brings a more pleasant driving experience to the owner.
