[0046] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.

[0047] The following is in conjunction with the appendix Figures 1-9 The housing component 101 of the air spring assembly 10 of this embodiment will be described in detail.

[0048] The air spring assembly 10 of this disclosure includes a housing component 101, which includes a first chamber 1011 and a second chamber 1012 arranged at intervals. The first chamber 1011 is used to house the shock absorber 102. The first chamber 1011 and the second chamber 1012 are communicable and detachable. The housing component 101 is a plastic part and includes a housing 1 and a housing seat 7 arranged sequentially from top to bottom. The top end of the housing seat 7 is connected to the bottom end of the housing 1. The housing 1 and the housing seat 7 are separately disposed. The first chamber 1011 includes an upper chamber 111 and a lower chamber 73 that are opposite to and communicate with each other in the vertical direction. The upper chamber 111 is formed in the housing 1, and the lower chamber 73 is formed in the housing seat 7. The second chamber 1012 is formed in at least one of the housing 1 and the housing seat 7.

[0049] The housing component 101 of the air spring assembly 10 of this disclosure is configured as a separate housing 1 and housing 7, which allows the housing 1 and housing 7 to be manufactured separately, reducing the manufacturing difficulty of the housing component 101. Moreover, the housing component 101 is made of plastic, which makes it easy to make the housing 1 and housing 7 into different shapes to meet diverse needs. This makes the outer peripheral shape of the housing component 101 more diverse, which is conducive to the adaptation of the housing component 101 to other components and also to the weight reduction of the housing component 101.

[0050] Specifically, such as Figures 1-7 As shown, the housing component 101 is sleeved on the outer periphery of the shock absorber 102, the upper chamber 111 is located above the lower chamber 73, the upper end of the inner wall surface of the upper chamber 111 is sealed to the shock absorber 102, and the lower end of the inner wall surface of the lower chamber 73 is sealed to the shock absorber 102, so that the inner peripheral surface of the housing component 101 and the outer peripheral surface of the shock absorber 102 form a first chamber 1011.

[0051] The second chamber 1012 is formed in at least one of the housing 1 and the housing base 7. This can be understood as: the second chamber 1012 is formed in the housing 1; or, the second chamber 1012 is formed in the housing base 7; or, the second chamber 1012 is formed in both the housing 1 and the housing base 7. In this embodiment, the second chamber 1012 is formed in both the housing 1 and the housing base 7.

[0052] Optionally, when the first chamber 1011 is connected to the second chamber 1012, the air spring assembly 10 operates in a low-stiffness mode, suitable for complex road conditions or curves. When the first chamber 1011 is disconnected from the second chamber 1012, the air spring assembly 10 operates in a high-stiffness mode, suitable for acceleration and high-speed straight-line driving conditions. By connecting and disconnecting the first chamber 1011 and the second chamber 1012, the different stiffnesses of the air spring assembly 10 can be adjusted.

[0053] Optionally, the first chamber 1011 and the second chamber 1012 can be connected and disconnected via a solenoid valve.

[0054] In some embodiments, such as Figures 6-9 As shown, the housing 1 includes a body portion 12 and a flange portion 13. The flange portion 13 extends radially outward from the bottom end of the body portion 12, forming the bottom end of the housing 1. The outer peripheral contour of the bottom end of the housing 1 is adapted to the outer peripheral contour of the top end of the housing base 7. By providing the flange portion 13 at the bottom end of the body portion 12, the outer peripheral contour of the bottom end of the housing 1 is adapted to the outer peripheral contour of the top end of the housing base 7, facilitating the connection between the bottom end of the housing 1 and the top end of the housing base 7.

[0055] In some embodiments, such as Figures 6-8 As shown, in the longitudinal section of the housing component 101, the flange portion 13 includes a first protrusion 131 and a second protrusion 132 arranged radially opposite to each other in the body portion 12. The distance between the outer end of the second protrusion 132 and the bottom end of the body portion 12 is greater than the distance between the outer end of the first protrusion 131 and the bottom end of the body portion 12. By setting the outward extension distance of the first protrusion 131 to be less than the outward extension distance of the second protrusion 132, it is easier to make the housing component 101 irregularly shaped, so that the housing component 101 can be better adapted to other components and adapt to complex and varied peripheral clearance requirements.

[0056] In some embodiments, the housing 1 includes a first segment 5 and a second segment 6 connected sequentially from top to bottom. The first segment 5 and the second segment 6 are separately disposed. The bottom end of the second segment 6 is connected to the top end of the housing base 7, and the bottom end of the second segment 6 forms a flange portion 13. The remaining portion of the second segment 6 and the first segment 5 form a body portion 12. By setting the housing 1 as separate first segment 5 and second segment 6, it is convenient to manufacture the first segment 5 and the second segment 6 separately, further reducing the manufacturing difficulty and cost of the housing component 101. Moreover, when repairing the housing component 101, partial replacement is possible instead of replacing the entire housing component 101, reducing maintenance costs and expenses, and increasing the service life of the housing component 101.

[0057] Specifically, such as Figures 6-8As shown, the bottom end of the first segment 5 is connected to the top end of the second segment 6, and the bottom end of the second segment 6 is connected to the top end of the housing 7. That is to say, the housing component 101 includes the first segment 5, the second segment 6 and the housing 7 connected from top to bottom to form a three-segment structure. The three-segment structure can match the irregular gaps of the chassis peripheral components, avoid interference between the housing component 101 and other components, and improve the structural compactness.

[0058] In some embodiments, the top end of the housing 7 is welded to the bottom end of the housing 1. By welding the top end of the housing 7 to the bottom end of the housing 1, the connection strength and sealing performance between the housing 7 and the housing 1 can be improved.

[0059] In some embodiments, the first segment 5 and the second segment 6 are welded together. By welding the first segment 5 and the second segment 6, the connection strength and sealing between the first segment 5 and the second segment 6 can be improved.

[0060] In some embodiments, such as Figures 3-7 As shown, the housing 1 also has an air intake channel 112, which is located on the outer periphery of the upper chamber 111. The second chamber 1012 includes the air intake channel 112. The upper end of the air intake channel 112 is adjacent to the upper end of the housing 1 and communicates with the outside. The lower end of the air intake channel 112 extends along the axial direction of the housing 1 to the lower end of the housing 1.

[0061] In this embodiment, an air intake channel 112 is provided on the outer periphery of the upper chamber 111, so that the air intake channel 112 and the upper chamber 111 are arranged radially spaced apart in the housing 1, making full use of the space inside the housing 1. Moreover, the upper end of the air intake channel 112 is connected to the outside, and the lower end of the air intake channel 112 extends to the lower end of the housing 1, which facilitates the entry of external gas into the lower end of the housing 1 through the upper end of the air intake channel 112, thereby improving the gas flow efficiency.

[0062] In some embodiments, such as Figure 7 As shown, in the longitudinal section of the housing component 101, the air intake passage 112 is located on one side of the upper chamber 111 in the radial direction of the housing 1. By setting the air intake passage 112 on one side of the upper chamber 111 in the radial direction of the housing 1, that is, by having the air intake passage 112 only surround a portion of the upper chamber 111 in the circumferential direction of the housing 1, rather than surrounding it completely, the volume of the upper chamber 111 is increased while still satisfying the requirement of communication and disconnection between the second chamber 1012 and the first chamber 1011. This improves the performance of the air spring assembly 10 and thus enhances user comfort.

[0063] In some embodiments, such as Figure 7As shown, the lower end of the intake passage 112 extends radially away from the upper chamber 111 in the housing 1. By extending the lower end of the intake passage 112 radially away from the upper chamber 111 in the housing 1, the space inside the housing 1 can be fully utilized, increasing the volume of the second chamber 1012.

[0064] In some embodiments, the housing 7 has a first connecting cavity 71 and a second connecting cavity 72 that can be connected and disconnected by a solenoid valve. The first connecting cavity 71 and the second connecting cavity 72 are located on the outer periphery of the lower chamber 73. The lower end of the second connecting cavity 72 and the air intake passage 112 are opposite to each other in the vertical direction and communicate with each other to form at least a portion of the second chamber 1012. The first connecting cavity 71 communicates with the upper end of the lower chamber 73. The lower end of the inner wall surface of the lower chamber 73 is sealed to the shock absorber 102.

[0065] Specifically, such as Figure 7 and Figure 9 As shown, the first connecting cavity 71 is located on the outer periphery of the lower chamber 73 and communicates with the upper end of the lower chamber 73, while the second connecting cavity 72 is located on the outer periphery of the lower chamber 73 and below the air intake channel 112. The first connecting cavity 71 communicates with the lower chamber 73, and the second connecting cavity 72 communicates with the air intake channel 112, facilitating the connection and disconnection of the first chamber 1011 and the second chamber 1012 through the connection and disconnection of the first connecting cavity 71 and the second connecting cavity 72.

[0066] Optionally, the first chamber 1011 and the second chamber 1012 can be connected and disconnected at the lower end of the housing component 101.

[0067] In some embodiments, such as Figure 3 and Figure 5 As shown, the inner wall of the upper chamber 111 is provided with an opening 3, which is connected to the upper end of the air intake channel 112. The top of the upper chamber 111 is open, and the upper end of the inner wall of the upper chamber 111 can be sealed with the shock absorber 102. The opening 3 is located above the sealing position of the wall of the upper chamber 111 and the shock absorber 102.

[0068] In this embodiment, by providing an opening 3 on the inner wall of the upper chamber 111, and the opening 3 being located above the sealing position of the damper 102, external gas can directly enter the air intake channel 112 through the opening 3 and flow to the second connecting cavity 72 through the lower end of the air intake channel 112. When the first connecting cavity 71 and the second connecting cavity 72 are connected, the gas in the second connecting cavity 72 can flow to the lower chamber 73 and the upper chamber 111, realizing rapid connection between the first chamber 1011 and the second chamber 1012, which is beneficial to improving the response speed of the air spring assembly 10.

[0069] The upper end of the inner wall of the upper chamber 111 is sealed to the vibration damper 102, and the lower end of the inner wall of the lower chamber 73 is sealed to the vibration damper 102. This makes the space between the lower part of the sealing position between the wall of the upper chamber 111 and the vibration damper 102 and the upper part of the sealing position between the wall of the lower chamber 73 and the vibration damper 102 sealed to the outside. In other words, outside gas can only enter the lower chamber 73 and the part of the upper chamber 111 connected to the lower chamber 73 through the air intake channel 112, the second connecting chamber 72 and the first connecting chamber 71.

[0070] In some embodiments, such as Figure 5 As shown, the inner wall of the upper chamber 111 has a protrusion 4, which is located below the opening 3 and is used to seal with the shock absorber 102.

[0071] In this embodiment, by placing the protrusion 4 below the opening 3 and sealing the protrusion 4 with the damper 102, the upper chamber 111 is divided into two parts in the vertical direction. The upper chamber 111 in the upper part is connected to the air intake channel 112 through the opening 3, and the upper chamber 111 in the lower part is connected to the lower chamber 73. The lower chamber 73 is connected to the first connecting cavity 71, and the air intake channel 112 is connected to the second connecting cavity 72. The connection and disconnection between the upper chamber 111 in the lower part and the second chamber 1012 are achieved by connecting and disconnecting the first connecting cavity 71 and the second connecting cavity 72.

[0072] Specifically, such as Figures 7-9 As shown, the lower chamber 73 and the first connecting chamber 71 are arranged radially spaced apart in the housing component 101. The inner wall surface of the lower chamber 73 is provided with a connecting groove 74, and the lower chamber 73 and the first connecting chamber 71 are connected through the connecting groove 74. The lower chamber 73 is sealed to the outside by the sealing fit between the lower end of the inner wall surface of the lower chamber 73 and the vibration damper 102.

[0073] Optionally, the housing component 101 further includes a spacer 61 disposed within the lower end of the second segment 6. The upper end of the spacer 61 is connected to the inner wall surface of the lower end of the second segment 6, and the lower end of the spacer 61 is spaced apart from the inner wall surface of the second segment 6. The spacer 61 is used to divide the upper chamber 111 into a main body segment and a connecting segment. The connecting segment is located outside the main body segment and is vertically opposite to and connected to the first connecting cavity 71. The lower chamber 73 is vertically opposite to and connected to the main body segment.

[0074] Optionally, the lower end of the isolation member 61 is provided with a mating groove 611 that is opposite to and communicates with the communicating groove 74. By setting the mating groove 611, the airflow area between the first communicating cavity 71 and the first chamber 1011 is increased, thereby improving the communication efficiency.

[0075] Optionally, there are multiple connecting grooves 74, and correspondingly, there are multiple mating grooves 611. The multiple connecting grooves 74 are arranged at intervals in the circumferential direction of the housing component 101.

[0076] The air spring assembly 10 of this disclosure includes the housing component 101 of the air spring assembly 10 of the above-described embodiments.

[0077] The air spring assembly 10 of this disclosure includes the housing component 101 of the air spring assembly 10 of the above embodiments, which can reduce the manufacturing difficulty of the air spring assembly 10 and improve the performance of the air spring assembly 10.

[0078] In some embodiments, the air spring assembly 10 further includes a top cover 104, a bladder 105, and a shock absorber 102. The top cover 104 is located above the housing component 101. The bladder 105 is disposed between the housing component 101 and the top cover 104 and defines a main cavity 109. The shock absorber 102 is sleeved in the main cavity 109 and a first chamber 1011 in the vertical direction. The inner wall surface of the top of the first chamber 1011 and the outer peripheral surface of the shock absorber 102 are spaced apart to form an annular channel 103. The main cavity 109 communicates with the annular channel 103. Gas in the main cavity 109 can enter the air intake channel 112 of the housing component 101 through the annular channel 103 and the opening 3 of the housing component 101. The air intake channel 112 and the lower chamber 73 can be disconnected and connected at the lower end of the housing component 101.

[0079] Specifically, such as Figures 1-3 As shown, the upper end of the bladder 105 is sealed to the top cover 104, and the lower end of the bladder 105 is sealed to the housing component 101. The inner circumferential surface of the bladder 105 defines the main cavity 109 between the lower end surface of the top cover 104 and the upper end surface of the housing component 101. The main cavity 109 is connected to the upper chamber 111 located in the upper part through an annular channel 103. The upper chamber 111 located in the upper part is connected to the air intake channel 112 through the opening 3, which increases the overall volume of the air spring assembly 10 and helps to improve the performance of the air spring assembly 10.

[0080] Optionally, the top cover 104 is made of aluminum and is used to connect to the vehicle to meet the requirements of high strength and high impact, thereby improving the impact resistance of the air spring assembly 10.

[0081] Compared to the method of setting a secondary cavity in the top cover 104 in related technologies, the arrangement of forming a first chamber 1011 and a second chamber 1012 by the housing component 101 in this embodiment makes the required tower space of the air spring assembly 10 smaller, which is conducive to the installation of the air spring assembly 10 and can be adapted to the chassis of compact vehicles.

[0082] Optionally, the top cover 104 is provided with an installation port, and the sealing cover 1041 is sealed and fitted inside the installation port to seal the main cavity 109 from the outside. For example, a third sealing element 1042 is provided between the sealing cover 1041 and the top cover 104.

[0083] In this embodiment, the shell component 101 is made of plastic and the top cover 104 is made of aluminum. By combining aluminum and plastic, lightweighting is achieved while ensuring connection strength, and environmental adaptability is improved by compensating for the difference in thermal expansion coefficients of the materials.

[0084] Optionally, such as Figures 1-2 As shown, the air spring assembly 10 also includes a protective sleeve 106 and a dust cover 107. The protective sleeve 106 is fitted around the outer periphery of the bladder 105 and connected to the bladder 105, while the protective sleeve 106 is connected to the dust cover 107. The protective sleeve 106 prevents the bladder 105 from over-expanding, improving the safety of the bladder 105. The dust cover 107 protects the housing component 101, extending its service life.

[0085] Specifically, the sleeve 106 is fitted around the outer periphery of the skin 105, wherein the upper part of the skin 105 is outside the sleeve 106, and the lower part of the skin 105 is inside the sleeve 106. The upper end of the sleeve 106 is connected to the skin 105, and the lower end of the sleeve 106 is connected to the upper end of the dust cover 107, the lower end of the dust cover 107 overlapping the shell component 101.

[0086] In some embodiments, such as Figure 3 and Figure 5 As shown, the air spring assembly 10 also includes a first seal 1081, which is disposed between the protrusion 4 of the housing component 101 and the outer peripheral surface of the shock absorber 102. By providing the first seal 1081 between the protrusion 4 and the outer peripheral surface of the shock absorber 102, a seal is achieved between the upper portion and the lower portion of the upper chamber 111.
