Detailed Implementation

[0053] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0054] Reference Figures 1 to 2 As shown, the first type of suspension assembly provided in this application includes: a connecting arm and a shock absorber assembly.

[0055] The connecting arm 100 is used to connect directly or indirectly to the wheels of the vehicle 1 (not shown in the figure), thereby transmitting the forces acting on the vehicle 1 to the shock absorber assembly 200. The shock absorber assembly 200 is disposed between the vehicle body and the connecting arm 100, thereby buffering the vibrations transmitted to the vehicle body.

[0056] Reference Figures 1 to 2 As shown, as a specific solution, the shock absorber assembly 200 mainly includes: an air spring 210, an actuator 220, a connecting cable 230, an electrical device 240, a plug-in terminal 250, a sealing device 260, a mounting flange 270, and an inner support component 280.

[0057] Specifically, the air spring 210 has an air chamber 210a; the actuator 220 is used to adjust the height of the air spring 210; wherein, the electrical device 240 can be set in the air chamber 210a. As a specific embodiment, the electrical device 240 can be a position sensor. Of course, the electrical device 240 can also be other types of sensors or control devices of the actuator 220, etc.

[0058] This effectively utilizes the space inside the air chamber 210a, ensuring the functionality of the electrical device 240 while also providing some protection for it. For example, the sensor can detect the actuator's action nearby or establish wiring and communication nearby, while the space where the sensor is located is enclosed to prevent dust and other factors from affecting its detection.

[0059] The air chamber 210a of the air spring 210 is mainly used to contain the pressure medium for shock absorption, which is generally a gaseous medium. As an option, the air spring 210 can be equipped with a corresponding valve, such as a solenoid valve, to control the amount of pressure medium in the air chamber 210a. More specifically, the air spring 210 can be a sleeve-type air spring.

[0060] The actuator 220 can be a cylinder mechanism or a linear motor. Generally, an electrical device 240 is installed in the damper assembly 200 to detect or actuate the movement of the actuator 220. In a damper assembly 200 that uses a coil spring as the damping element, the coil spring and the electrical device 240 are often staggered in the extension and contraction direction of the coil spring to avoid interference. This results in an excessively large overall size and difficult wiring. In a damper assembly 200 that uses an air spring 210 as the damping element, the electrical device 240 is often placed outside the air spring 210. However, this makes the electrical device 240 very susceptible to external influences, and similar to the damper assembly 200 using a coil spring, it also increases the overall size of the damper assembly 200.

[0061] The technical solution provided in this application covers and protects the electrical device 240 by placing the electrical device 240 in the air chamber 210a of the air spring 210. At the same time, the size of the shock absorber assembly 200 is reduced due to the spatial overlap between the electrical device 240 and the air spring 210.

[0062] Reference Figures 1 to 2 As shown, the shock absorber assembly 200 of this application has a wiring channel 230a formed between the air spring 210 and the actuator 220 for the connection cable 230 to pass through. To allow the connection cable 230 to enter the air chamber 210a, the air chamber 210a of the air spring 210 is connected to the wiring channel 230a. Furthermore, the air chamber 210a of the air spring 210 is isolated from the external space by a sealing device 260.

[0063] In order to enable external devices to be connected to the electrical device 240, the vibration damper assembly 200 of this application is provided with a plug-in terminal 250, which is electrically connected to the connecting cable 230 for the external device to be plugged in.

[0064] As a specific embodiment, the actuator 220 of this application includes: an actuator housing 221 and an actuator link 222. The actuator housing 221 has a receiving cavity 221a, which can accommodate the internal components of the actuator 220. For example, when the actuator 220 is a linear motor, the receiving cavity 221a can accommodate the stator of the linear motor. The actuator link 222 is movably connected to the actuator housing 221.

[0065] As a more specific embodiment, the execution housing 221 can be a single, complete housing, meaning that all parts forming the receiving cavity 221a are constituted by the execution housing 221. Alternatively, the receiving cavity 221a can also be composed of the execution housing 221 and other parts. (Refer to...) Figure 1 and Figure 2As shown, in a specific embodiment, the bottom of the actuator housing 221 is open, and the top of the connecting arm 100 forms an end cap 101 with a flange. It is then installed to the actuator housing 221 by mounting bolts 102 to form a complete air chamber 210a, which also achieves a fixed connection of the connecting arm 100.

[0066] As a specific embodiment, the air spring 210 of this application includes: an air spring piston 211, an air spring base 212, an air spring bladder 213, an air spring cylinder 214, a support ring 215, a first pressure ring 216, a second pressure ring 217, and a dust cover 218.

[0067] The air spring base 212 is fixedly connected to the actuating link 222. The air spring base 212 is used to connect to the vehicle body, and multiple connecting bolts 219 are connected to the air spring base 212 to facilitate the connection of the shock absorber assembly 200 to the vehicle body. This is equivalent to setting the connection interface of the shock absorber assembly 200 at the end and reusing the structure of the air spring 210, which facilitates installation and simplifies the structure.

[0068] The air spring piston 211 is fixedly connected to the actuator housing 221; the air spring bladder 213 is connected to both the air spring piston 211 and the air spring base 212; wherein the air spring bladder 213 surrounds at least a portion of the actuator 220 to form an air cavity 210a around the actuator 220. This effectively reuses the space of the air spring 210 in part of the actuator 220, reducing the height dimension of the damper assembly 200 and saving installation space.

[0069] Reference Figures 1 to 2 As shown, in a more specific embodiment, the first pressure ring 216 is used to fix the air spring bladder 213 to the air spring base 212; the second pressure ring 217 is used to fix the air spring bladder 213 to the air spring piston 211; the first pressure ring 216 and the second pressure ring 217 can be configured as clamps.

[0070] As a more specific embodiment, the spring retainer 214 is fitted onto the outside of the spring bladder 213; a support ring 215 is used to fix the spring bladder 213 to the spring retainer 214; wherein, the support ring 215 is disposed inside the spring bladder 213; the spring bladder 213 is at least partially disposed between the support ring 215 and the spring retainer 214. The spring retainer 214 is mainly used to limit the expansion range of the spring bladder 213. A dust cover 218 is fixedly installed to the spring retainer 214, and its main function is to prevent foreign objects from entering the folds of the spring bladder 213.

[0071] As a specific embodiment, the air spring piston 211 includes a piston portion 211a and a sleeve portion 211b. The piston portion 211a connects to the air spring housing 213; the sleeve portion 211b surrounds at least a portion of the actuator 220 to form a space 211c around the actuator 220. The wiring channel 230a of this application is at least partially formed in the space 211c, meaning that the connecting cable 230 is routed through the channel (i.e., wiring channel 230a) formed by a portion of the space in the space 211c. In this way, the sleeve portion 211b can protect the actuator 220 and also constitutes a relatively enclosed space.

[0072] Reference Figure 4 As shown, in a specific embodiment, a wire groove 221c is formed on the outer side of the housing 221; the wire groove 221c forms at least a portion of the wiring channel 230a. Furthermore, the wire groove 221c includes a first extension segment 221d and a second extension segment 221e having opposite extending directions. More specifically, the extending directions of the first extension segment 221d and the second extension segment 221e intersect perpendicularly. In this way, the connecting cable 230 can be routed along the wiring channel 230a to the corresponding circumferential position.

[0073] Reference Figures 1 to 2 As shown, in order to seal the interlayer space 211c by closing the ends of the actuator housing 221 and the air spring piston 211, the damper assembly 200 of this application is provided with a mounting flange 270. The mounting flange 270 forms a flange cavity 270a and is fixedly mounted to the actuator housing 221. The mounting flange 270 can effectively connect the plug terminal 250 to the whole formed by the air spring 210 and the actuator 220.

[0074] The flange cavity 270a is connected to the wiring channel 230a so that the connecting cable 230 can extend into the flange cavity 270a; the end of the sleeve portion 211b abuts against the mounting flange 270; more specifically, the mounting flange 270 is formed with a positioning step 273; the end of the sleeve portion 211b is engaged with the positioning step 273.

[0075] The above structure allows for wiring routing on the mounting flange 270 and provides a relatively stable and reliable positioning for the air spring piston 211. To achieve a seal, the sealing device 260 includes a flange sealing ring 261. The flange sealing ring 261 seals the gap between the sleeve portion 211b and the mounting flange 270; wherein, the flange sealing ring 261 is disposed between the sleeve portion 211b and the mounting flange 270. To further enhance the seal, the sleeve portion 211b has a sealing rib 211d corresponding to the flange sealing ring 261 inside. The sealing rib 211d contacts the flange sealing ring 261 to ensure sealing performance.

[0076] As a specific embodiment, the mounting flange 270 is constructed with a first flange housing 271 and a second flange housing 272, meaning the mounting flange 270 is constructed as a two-part structure. A complete mounting flange 270 can be formed by mating the first flange housing 271 and the second flange housing 272. To achieve a seal between the first flange housing 271 and the second flange housing 272, the sealing device 260 also includes a half-shell sealing ring, which is used to seal the gap between the first flange housing 271 and the second flange housing 272; wherein the first flange housing 271 and the second flange housing 272 are disposed between the first flange housing 271 and the second flange housing 272. The two-part structure facilitates installation and disassembly.

[0077] Reference Figure 2 As shown, the inner support member 280 is disposed in the inner cavity 270a of the flange; wherein, the inner support member 280 is disposed between the actuator housing 221 and the mounting flange 270.

[0078] Reference Figure 2 As shown, the mounting flange 270 has a through hole for the plug-in terminal 250 to pass through the wall of the mounting flange 270. It should be noted that the plug-in terminal and the mounting flange 270 can be sealed by sealing ring or potting.

[0079] Reference Figure 2 As shown, the air spring base 212 includes a base bushing and a base positioning ring 212a, which can be made of metal. The base bushing and base positioning ring 212a are used to directly fit onto the actuating link 222. The sealing device 260 also includes a link sealing ring 264. The link sealing ring 264 is used to seal the gap between the link and the base bushing and the base positioning ring 212a. Furthermore, the base bushing and base positioning ring 212a is provided with a bushing groove and a positioning ring groove 212b for accommodating the link sealing ring 264. That is, the link sealing ring 264 is accommodated in the bushing groove and the positioning ring groove 212b, so that the actuating link 222 can have a smooth surface. More specifically, the actuating link 222 and the base bushing base positioning ring 212a form an anti-rotation connection; the actuating link 222 has a link groove and a link step 222a for the base bushing base positioning ring 212a to be inserted into, and there is also an anti-rotation structure (not shown in the figure) between the actuating link 222 and the base positioning ring 212a to prevent them from rotating, such as a spline or a groove and a protrusion that cooperate with each other. This prevents the relative rotation of the actuating link 222 with respect to the air spring base 212.

[0080] Reference Figure 2As shown, the execution housing 221 has a housing channel 221b that connects the receiving cavity 221a and the air cavity 210a, which enables the components in the receiving cavity 221a of the execution housing 221 to be cooled.

[0081] Reference Figures 3 to 5 As shown, the second type of suspension assembly 10 provided in this application is similar to... Figures 1 to 2 The difference in the first type of suspension assembly 10 shown is that the mounting flange 270 is eliminated. Instead, the positioning step 273 is directly formed by the actuator housing 221, and the actuator housing 221 directly forms a terminal groove 221g to accommodate the plug-in terminal 250 and a through hole (not shown in the figure) for the plug-in terminal 250 to be exposed. That is, the actuator housing 221 forms a terminal groove 221g; the terminal groove 221g communicates with the wiring channel 230a so that the connecting cable 230 can extend to the plug-in terminal 250 in the terminal groove 221g; in addition, in order to prevent leakage from the through hole through which the plug-in terminal 250 passes, a sealing ring (not shown in the figure) or potting compound can be provided in the terminal groove 221g to ensure the sealing effect at that point. This eliminates the need for the mounting flange 270, thereby improving the integration of the structure and reducing the installation difficulty.

[0082] Reference Figure 5 As shown, to achieve the sealing of the air chamber 210a, a shell sealing ring 263 is provided between the actuator housing 221 and the sleeve portion 211b in the second type of suspension assembly 10. The shell sealing ring 263 is used to seal the gap between the sleeve portion 211b and the actuator housing 221. To ensure the sealing effect, multiple shell sealing rings 263 can be provided. Compared with the first type of suspension assembly 10, the second type of suspension assembly 10 only needs to seal the space between the actuator housing 221 and the air spring piston 211 to achieve the sealing of the air chamber 210a, and the structure is more reliable.

[0083] Reference Figures 6 to 7 As shown, the third type of suspension assembly 10 provided in this application is similar to... Figures 3 to 5 The difference in the second type of suspension assembly 10 shown is that the air spring piston 211 is eliminated, and instead, the actuator housing 221 of the actuator 220 serves as the air spring piston 211. Specifically, the air spring bladder 213 of the air spring 210 is directly connected to the actuator 220. At the same time, the wiring channel 230a is directly formed by the actuator housing 221, which reduces the complexity of the sealing device 260.

[0084] use Figures 6 to 7 In the illustrated scheme, the second pressure ring 217 directly fixes the air spring bladder 213 to the actuator housing 221.

[0085] In Adoption Figures 6 to 7In the solution shown, it is only necessary to effectively seal the end of the wiring channel 230a (that is, the part that connects with the electrical device 240) to achieve effective sealing of the air chamber 210a.

[0086] Reference Figures 8 to 11 As shown, the first type of electrical device 240 provided in this application specifically includes: an electrical component 241 and a device housing 242. The electrical component 241 is used to perform electrical functions, such as the probe of a magnetic encoder; the device housing 242 has a first device cavity 242a for accommodating the electrical component 241; wherein the first device cavity 242a communicates with a wiring channel 230a, so that the connecting cable 230 and the electrical component 241 are electrically connected.

[0087] Reference Figures 8 to 11 As shown, in a more specific embodiment, the device housing 242 forms a device channel 242g that communicates with the first device cavity 242a; the device channel 242g is disposed between the first device cavity 242a and the wiring channel 230a and communicates with the wiring channel 230a; that is, the first device cavity 242a and the wiring channel 230a are indirectly connected.

[0088] To achieve a sealing effect, the sealing device 260 also includes a channel sealing ring 265; the channel sealing ring 265 is used to seal the gap between the actuator housing 221 and the device housing 242. The channel sealing ring 265 is disposed between the actuator housing 221 and the device housing 242; the actuator housing 221 has a channel sealing groove 221f on its end face that contacts the device housing 242 to accommodate the channel sealing ring 265.

[0089] Furthermore, the interior of the device housing 242 can be filled with sealing glue through methods such as potting, thereby sealing both the chamber and the passage of the electrical device 240.

[0090] In addition, in order to install the electrical device 240 to the actuator housing 221, the damper assembly 200 also includes: a fixing bolt (not shown in the figure); the fixing bolt is used to fix the device housing 242 to the actuator housing 221; wherein the device housing 242 is formed with a device through hole 242f; the actuator housing 221 is formed with a fixing screw hole; the fixing bolt passes through the device through hole 242f and is screwed into the fixing screw hole.

[0091] The device housing 242 has a device through hole 242f; the actuator housing 221 has a fixing screw hole; the fixing bolt passes through the device through hole 242f and is screwed into the fixing screw hole; this allows the electrical device 240 to be installed securely.

[0092] Reference Figures 12 to 15 As shown, the second type of electrical device 240 provided in this application is related to... Figures 8 to 11 The difference between the first type of electrical device 240 shown is that the device housing 242 of the second type of electrical device 240 forms a second device cavity 242b for accommodating electrical components 241; the device housing 242 also forms an internal channel 242c that communicates with the first device cavity 242a and the second device cavity 242b.
