[0021] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting", "fixing" and the like should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or integrated; can be mechanical connection, can also be electrical connection, or communication; can be directly connected, or indirectly connected through an intermediate medium; can be the communication or interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0022] In the present application, unless otherwise explicitly specified and limited, the terms "first", "second" are only for description purpose, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly specified and limited.

[0023] Reference Figures 1 to 5The embodiment discloses an air spring structure, which comprises a gas bag 1, a rotating cover 2, a mounting seat 3, an upper buffer pad 4, an upper 3M adhesive pad 5, a lower buffer pad 6 and a lower 3M adhesive pad 7, rotating covers 2 and mounting seats 3 are arranged at the upper and lower ends of the gas bag 1 respectively, the upper surface of the rotating cover 2 is bonded to the upper buffer pad 4 through the upper 3M adhesive pad 5, and the bottom surface of the mounting seat 3 is bonded to the lower buffer pad 6 through the lower 3M adhesive pad 7.

[0024] In the embodiment, the upper buffer pad 4 has a circular structure and a thickness of 2 mm, and the upper buffer pad 4 is a rubber pad, but is not limited to the material, and any material having a buffering effect can be used. Specifically, the upper 3M adhesive pad 5 is uniformly bonded to the upper buffer pad 4, the bonding thickness is not less than 0.27 mm, dust and impurities are removed from the surface of the buffer pad before bonding, and the overflow width of the adhesive pad after bonding is not greater than 0.5 mm. The material grade of the upper 3M adhesive pad 5 is 3M 9448A, the adhesive tape thickness is 0.15 mm, the bonding strength is not less than 1.05 N / mm, and the adhesive tape can resist high temperature, that is, long-term resistance to temperature of 70 DEG C and short-term resistance to temperature of 150 DEG C.

[0025] The lower buffer pad 6 is provided with petal-shaped structures around, so that notches are formed between adjacent petal-shaped structures, and the lower 3M adhesive pad 7 corresponds to the shape of the lower buffer pad 6. The notches formed between adjacent petal-shaped structures are beneficial to air exhaust of the gas bag 1. If the lower buffer pad 6 and the lower 3M adhesive pad 7 do not have four notches, air in the gas bag 1 cannot be exhausted when the mounting seat 3 is assembled with the vehicle body and the gas bag 1 is restored from a lower jump position to a design position, so that the gas bag 1 appears to be concave.

[0026] In the embodiment, the thickness of the lower buffer pad 6 is 8 mm, and the lower buffer pad 6 is a polyurethane rubber pad, which has strong molecular bonding capacity, resistance to hydrolysis, resistance to low temperature and excellent elastic properties, but is not limited to the material, and any material having a buffering effect can be used. The bonding method of the lower 3M adhesive pad 7 and the lower buffer pad 6 is the same as the bonding method of the upper 3M adhesive pad 5 and the upper buffer pad 4.

[0027] In the embodiment, the upper buffer pad 4 cooperates with the rotating cover 2, so that air spring abnormal sound caused by low flatness of a vehicle body connecting surface can be solved when the vehicle is in motion. The lower buffer pad 6 cooperates with the mounting seat 3, so that stress concentration can be effectively prevented, air spring axial and radial stiffness can be decoupled, small-amplitude high-frequency vibration in the process of vehicle driving can be effectively filtered, and vibration filtering effect can be achieved.

[0028] In addition, the upper buffer pad 4 and the lower buffer pad 6 have simple structures and are easy to assemble, can buffer and disperse the energy of the air spring, and improve the riding comfort. In addition, the upper buffer pad 4 and the lower buffer pad 6 have buffering and vibration filtering effects, and can participate in vehicle driving evaluation and adjustment, so that the vehicle comfort can be improved.
