AI Technical Summary
In the suspension system, the lack of positioning during the installation of the air spring leads to assembly failure, especially due to the insufficient length of the guide column, making it difficult to accurately insert into the mounting positioning hole of the guide bushing.
A suspension positioning component was designed. By setting a telescopic first guide post and a second guide post, the overall length of the guide post is increased. A limiting structure and a mating structure are set in the positioning hole to ensure that the guide post remains stably positioned during the air spring lifting process.
This improves the assembly accuracy of air springs and the success rate of guide bushing assembly, ensuring accurate docking between air springs and guide bushings, preventing circumferential rotation, and promoting stable installation of the suspension system.

Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle component manufacturing technology, and in particular to a suspension positioning component, a suspension system, and a vehicle. Background Technology
[0002] The suspension system is a crucial component of a vehicle, connecting the body and axles. It supports the vehicle, transmits forces and torques, dampes and cushions vibrations, and maintains driving stability. The suspension system mainly includes components such as elastic elements, shock absorbers, guide bushings, stabilizer bars, and cantilever arms. During installation, the elastic elements need to be pre-positioned with the guide bushings before being connected to the vehicle body using bolts and other fasteners.
[0003] Figure 1 This is a simplified structural diagram of the suspension positioning component in a related technical solution. (Example:) Figure 1 As shown, in the related technical solution, the suspension positioning assembly includes an air spring 10 and a guide bushing 20. One end of the air spring 10 is fixed to the axle, and the other end of the air spring 10 is provided with a mounting positioning hole 11. The guide bushing 20 is fixed to the vehicle body, and a guide post 21 is provided on the guide bushing 20. During installation, air needs to be inflated into the air spring 10 to lift it, so that the air spring 10 gradually approaches the guide bushing 20, and finally the guide post 21 is inserted into the mounting positioning hole 11.
[0004] However, in the related technical solutions, due to the limited depth of the mounting positioning hole 11, the guide column 21 is relatively short, and the air spring 10 lacks positioning during the lifting process, which makes it easy for the air spring 10 to be installed in the wrong position, thus leading to assembly failure. Utility Model Content
[0005] In view of this, the present application provides a suspension positioning component, a suspension system and a vehicle. The present application is beneficial to improving the positioning accuracy during air spring assembly and improving the assembly success rate of air spring and guide bushing.
[0006] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:
[0007] This application provides a suspension positioning component, including:
[0008] An air spring, one end of which is provided with a positioning hole, the positioning hole including a first positioning hole and a second positioning hole that are connected to each other, the first positioning hole being far away from the opening of the positioning hole, and the diameter of the first positioning hole being smaller than the diameter of the second positioning hole;
[0009] A guide pad, the guide pad including a pad body and a guide post disposed on one side of the pad body, the guide post including a first guide post and a second guide post, the second guide post being sleeved on the first guide post, the first guide post being away from the pad body, and the first guide post being movable relative to the second guide post.
[0010] The air spring and the guide pad have a first state and a second state relative to each other; in the first state, at least a portion of the first guide post is inserted into the first positioning hole and is fixedly connected to the first positioning hole, and the air spring can drive the first guide post to move into the second guide post; in the second state, the second guide post is inserted into the second positioning hole, and the air spring abuts against the pad body.
[0011] This embodiment of the application increases the overall length of the guide post by setting a retractable and movable first guide post. The first guide post can be inserted into the first positioning hole before the air spring is inflated and lifted, thus achieving guiding and positioning. During the air spring lifting process (i.e., in the first state), the first guide post is gradually compressed into the second guide post by the air spring, and the second guide post is inserted into the second positioning hole to continue guiding and positioning the air spring. After the air spring is lifted to its final position (i.e., in the second state), the second guide post is fully inserted into the second positioning hole, and the air spring abuts against the gasket body. This application helps improve the positioning accuracy during air spring assembly and increases the success rate of assembling the air spring and guide gasket.
[0012] In one possible implementation of this application, the first guide post is interference-fitted with the first positioning hole.
[0013] In this embodiment, by interfering with the first guide post and the first positioning hole, the stability of the connection between the first guide post and the first positioning hole is ensured, and the first guide post will not fall out of the first positioning hole during the air spring lifting process. Thus, the guide post plays a guiding and positioning role throughout the entire lifting process of the air spring.
[0014] In one possible implementation of this application, at least one limiting structure is provided in the positioning hole, and at least one mating structure is provided on the guide post. The limiting structure and the mating structure cooperate to restrict the relative rotation of the air spring and the guide pad along the circumferential direction of the air spring.
[0015] This embodiment of the application sets a limiting structure in the positioning hole and a mating structure on the guide post. The limiting structure and the mating structure cooperate to restrict the relative rotation of the air spring and the guide pad in the circumferential direction of the air spring. This can prevent the air spring from rotating in the circumferential direction during the lifting process, and ensure that the installation angle does not change after the air spring is lifted into place, which facilitates the subsequent connection of the air spring with other components.
[0016] In one possible implementation of this application, the limiting structure includes a groove disposed in the positioning hole, and the mating structure includes a protrusion disposed on the guide post;
[0017] Alternatively, the limiting structure may include a protrusion disposed within the positioning hole, and the mating structure may include a groove disposed on the guide post.
[0018] In this embodiment, the positioning hole groove engages with the corresponding protrusion on the guide post; or, the positioning hole protrusion engages with the corresponding groove on the guide post, thereby limiting the air spring and guide pad in the circumferential direction. This prevents the air spring from rotating circumferentially during the lifting process, ensuring that the installation angle does not change after the air spring is lifted into place, which facilitates the subsequent connection of the air spring with other components.
[0019] In one possible implementation of this application, the limiting structure includes a first groove disposed within the first positioning hole; the mating structure includes a first protrusion disposed on the first guide post.
[0020] In this embodiment, the first groove in the first positioning hole engages with the first protrusion on the first guide post, thereby limiting the air spring and guide pad in the circumferential direction, preventing the air spring from rotating circumferentially during lifting, ensuring that the installation angle does not change after the air spring is lifted into place, and facilitating the subsequent connection of the air spring with other components.
[0021] In one possible implementation of this application, the limiting structure further includes a second groove disposed in the second positioning hole, and the mating structure further includes a second protrusion disposed on the second guide post, wherein a guide groove is formed in the second protrusion, and at least a portion of the first protrusion passes through the guide groove.
[0022] In this embodiment, the second groove in the second positioning hole engages with the second protrusion on the second guide post, thereby further strengthening the circumferential limiting of the air spring and guide pad. Furthermore, the guide groove in the second protrusion can also allow the first protrusion to pass through, guiding the sliding of the first and second protrusions. By having the first protrusion pass through the guide groove of the second protrusion, relative movement in the circumferential direction between the first and second guide posts can also be prevented.
[0023] In one possible implementation of this application, the guide post further includes at least one intermediate guide post located between the first guide post and the second guide post; the intermediate guide post is sleeved on the first guide post, and the first guide post is movable relative to the intermediate guide post; the second guide post is sleeved on the intermediate guide post, and the intermediate guide post is movable relative to the second guide post.
[0024] This embodiment of the application provides at least one intermediate guide post between the first guide post and the second guide post, thereby reducing the length of each guide post segment and ensuring that the length of each guide post segment does not exceed the length of the second guide post. During the air spring lifting process, other guide posts outside the second guide post can be compressed one by one into the second guide post, thereby better guiding and positioning the air spring.
[0025] In one possible implementation of this application, the intermediate guide post includes a third guide post and a fourth guide post; the third guide post is sleeved on the first guide post, and the first guide post is movable relative to the third guide post; the fourth guide post is sleeved on the third guide post, and the third guide post is movable relative to the fourth guide post; the second guide post is sleeved on the fourth guide post, and the fourth guide post is movable relative to the second guide post.
[0026] In this embodiment, by setting a third and fourth guide post between the first and second guide posts, the lengths of the first, third, and fourth guide posts all exceed the length of the second guide post. During the air spring lifting process, the first, third, and fourth guide posts can be compressed one by one into the second guide post, thereby achieving better guidance and positioning of the air spring.
[0027] This application also provides a suspension system including any of the suspension positioning components described above.
[0028] The suspension system of this application embodiment adopts the above-mentioned suspension positioning components, which helps to improve the positioning accuracy during air spring assembly and increase the success rate of air spring and guide bushing assembly.
[0029] This application also provides a vehicle including the suspension system described above.
[0030] The vehicle in this embodiment of the application uses the above-described suspension system, which helps to improve the positioning accuracy during air spring assembly and increase the success rate of air spring and guide bushing assembly. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.
[0040] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.
[0041] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.
[0042] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.
[0043] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0044] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.
[0045] As described in the background section, in the related art solutions, the air spring lacks proper positioning during the lifting process when assembling the suspension positioning component, which can easily lead to improper installation of the air spring and thus assembly failure. Specifically, Figure 1 An exploded view of a suspension positioning assembly in the related art is shown, such as Figure 1 As shown, in the related technical solution, the suspension positioning assembly includes an air spring 10 and a guide bushing 20. One end of the air spring 10 is fixed to the axle, and the other end of the air spring 10 is provided with a mounting positioning hole 11. The guide bushing 20 is fixed to the vehicle body, and a guide post 21 is provided on the guide bushing 20. During installation, air needs to be inflated into the air spring 10 to lift it, so that the air spring 10 gradually approaches the guide bushing 20, and finally the guide post 21 is inserted into the mounting positioning hole 11.
[0046] Understandably, due to the limited depth of the mounting positioning hole 11, the length of the guide post 21 is relatively short (the length of the guide post 21 is less than or equal to the depth of the mounting positioning hole 11). When the air spring 10 is lifted, it can only play its guiding and positioning role on the air spring 10 after contacting the guide post 21. Before that, the air spring 10 may experience problems such as offset or deflection, which will prevent the air spring 10 from successfully assembling with the guide pad 20.
[0047] In view of this, the embodiments of this application aim to provide a suspension positioning component, a suspension system, and a vehicle. By setting a telescopically movable first guide post and a second guide post, the overall length of the guide post is increased. The first guide post can be inserted into the first positioning hole before the air spring is inflated and lifted, thereby achieving guiding positioning. During the air spring lifting process, the first guide post is gradually compressed into the second guide post by the air spring, and the second guide post is inserted into the second positioning hole to continue guiding and positioning the air spring. After the air spring is lifted into position, the second guide post is fully inserted into the second positioning hole, and the air spring abuts against the bushing body. This application helps to improve the positioning accuracy during air spring assembly and increases the success rate of assembly of the air spring and guide bushing.
[0048] The embodiments of this application are described in detail below with reference to the accompanying drawings, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.
[0049] This application provides a suspension positioning component, a suspension system, and a vehicle for assisting in the assembly of the suspension system. It should be noted that the vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Vehicles generally have wheels, a body, and a suspension system installed between the wheels and the body. The suspension system can transmit the forces and torques acting between the wheels and the body, buffer the impact forces transmitted from uneven road surfaces to the frame or body, and dampen the resulting vibrations to ensure smooth vehicle operation.
[0050] Please refer to Figure 2 and Figure 3 ,in, Figure 2 An exploded view of the suspension positioning assembly before assembly is shown, and Figure 3 shows a simplified structural diagram of the guide bushing after the suspension positioning assembly is in place. Embodiments of this application provide a suspension positioning assembly, including:
[0051] An air spring 100 has a positioning hole at one end, which is located at the end of the air spring 100 furthest from the axle. The positioning hole includes a first positioning hole 110 and a second positioning hole 120 that are connected. The first positioning hole 110 is located away from the opening of the positioning hole, and its diameter is smaller than that of the second positioning hole 120. The first positioning hole 110 and the second positioning hole 120 together form a stepped hole structure. The air spring 100 may also have an air pipe interface 130 for connecting to an external inflation device to inflate the air spring 100 and thus lift it.
[0052] A guide liner 200 includes a liner body 210 and a guide post disposed on one side of the liner body 210. It is understood that the liner body 210 is used to connect to the vehicle body, and the guide post can be disposed on the side of the liner body 210 opposite to the vehicle body. The guide post includes a first guide post 220 and a second guide post 230. The second guide post 230 is sleeved on the first guide post 220, the first guide post 220 is away from the liner body 210, and the first guide post 220 is movable relative to the second guide post 230. Exemplarily, in this embodiment, the second guide post 230 is fixedly connected to the liner body 210, and at least a portion of the first guide post 220 is slidably disposed inside the second guide post 230. The sliding fit structure between the first guide post 220 and the second guide post 230 can be determined as needed.
[0053] In this embodiment, the air spring 100 and the guide pad 200 have relative first and second states. In the first state, at least a portion of the first guide post 220 is inserted into the first positioning hole 110 and fixedly connected to it. When the air spring 100 is lifted, it can be guided and positioned using the first guide post 220, and the first guide post 220 is moved into the second guide post 230. In the second state, the second guide post 230 is inserted into the second positioning hole 120, and the air spring 100 abuts against the pad body 210, thereby completing the assembly of the air spring 100 and the guide pad 200.
[0054] This embodiment of the application increases the overall length of the guide post by providing a retractable and movable first guide post 220. Before the air spring 100 is inflated and lifted, the first guide post 220 can be inserted into the first positioning hole 110, thus achieving guiding and positioning of the air spring 100 during lifting. During the lifting process of the air spring 100 (i.e., in the first state), the first guide post 220 is gradually compressed by the air spring 100 into the second guide post 230, and the second guide post 230 is inserted into the second positioning hole 120 to continue guiding and positioning the air spring 100. After the air spring 100 is lifted to its position (i.e., in the second state), the second guide post 230 is fully inserted into the second positioning hole 120, and the air spring 100 abuts against the pad body 210.
[0055] Since the air spring 100 is guided and positioned throughout the lifting process, this application helps to improve the positioning accuracy of the air spring 100 during assembly and increase the success rate of assembling the air spring 100 and the guide pad 200.
[0056] Preferably, the first guide post 220 and the first positioning hole 110 in this embodiment of the application can be interference-fitted. For example, the size of the first guide post 220 can be set to be slightly larger than the inner diameter of the first positioning hole 110. Before the air spring is inflated and lifted, it presses part of the first guide post 220 into the first positioning hole 110, thereby achieving an interference fit between the first guide post 220 and the first positioning hole 110.
[0057] In this embodiment, by interfering with the first guide post 220 and the first positioning hole 110, the stability of the connection between the first guide post 220 and the first positioning hole 110 is ensured, and the first guide post 220 will not fall out of the first positioning hole 110 during the lifting process of the air spring 100. Thus, the guide post plays a guiding and positioning role throughout the entire lifting process of the air spring 100.
[0058] Please continue to refer to Figure 2 In this embodiment of the application, at least one limiting structure is provided in the positioning hole, and at least one matching structure is provided on the guide post. The limiting structure and the matching structure cooperate to restrict the air spring 100 and the guide pad 200 from rotating relative to each other in the circumferential direction of the air spring 100.
[0059] This embodiment of the application sets a limiting structure in the positioning hole and a mating structure on the guide post. The limiting structure and the mating structure cooperate to restrict the relative rotation of the air spring 100 and the guide pad 200 in the circumferential direction of the air spring 100. This can prevent the air spring 100 from rotating in the circumferential direction during the lifting process, and ensure that the installation angle of the air spring 100 does not change after it is lifted into place, which facilitates the subsequent connection of the air spring 100 with other components.
[0060] Optionally, the limiting structure in this application embodiment includes a groove disposed in the positioning hole, and the mating structure includes a protrusion disposed on the guide post.
[0061] Alternatively, the limiting structure includes a protrusion disposed in the positioning hole, and the mating structure includes a groove disposed on the guide post.
[0062] In this embodiment, the positioning hole groove engages with the corresponding protrusion on the guide post; or, the positioning hole protrusion engages with the corresponding groove on the guide post, thereby limiting the air spring 100 and the guide pad 200 in the circumferential direction. This prevents the air spring 100 from rotating circumferentially during the lifting process, ensuring that the installation angle of the air spring 100 does not change after it is lifted into place, which facilitates the subsequent connection of the air spring 100 with other components.
[0063] Specifically, the limiting structure of this application embodiment includes a first groove 111 disposed in the first positioning hole 110; the mating structure includes a first protrusion 221 disposed on the first guide post 220.
[0064] In this embodiment, the first groove 111 in the first positioning hole 110 cooperates with the first protrusion 221 on the first guide post 220, thereby limiting the air spring 100 and the guide pad 200 in the circumferential direction, preventing the air spring 100 from rotating circumferentially during the lifting process, ensuring that the installation angle of the air spring 100 will not change after it is lifted into place, and facilitating the subsequent connection of the air spring 100 with other components.
[0065] Furthermore, the limiting structure in this embodiment further includes a second groove 121 disposed within the second positioning hole 120, and the mating structure further includes a second protrusion 231 disposed on the second guide post 230. A guide groove is formed within the second protrusion 231, and at least a portion of the first protrusion 221 passes through the guide groove. Exemplarily, the guide groove in this embodiment includes an opening facing the first guide post 220 and a stop portion opposite to the opening. The first protrusion 221 can pass through the opening into the guide groove, and the stop portion can abut against the first protrusion 221, thereby limiting the length by which the first guide post 220 slides into the second guide post 230.
[0066] In this embodiment, the second groove 121 in the second positioning hole 120 engages with the second protrusion 231 on the second guide post 230, thereby further strengthening the circumferential limiting of the air spring 100 and the guide pad 200. Furthermore, the guide groove in the second protrusion 231 allows the first protrusion 221 to pass through, guiding the sliding of the first protrusion 221 and the second protrusion 231. The passage of the first protrusion 221 through the guide groove of the second protrusion 231 also prevents relative circumferential movement between the first guide post 220 and the second guide post 230.
[0067] Please continue to refer to Figure 2 In this embodiment of the application, the guide post further includes at least one intermediate guide post, which is located between the first guide post 220 and the second guide post 230. The intermediate guide post is sleeved on the first guide post 220, and the first guide post 220 is movable relative to the intermediate guide post. The second guide post 230 is sleeved on the intermediate guide post, and the intermediate guide post is movable relative to the second guide post 230.
[0068] In this embodiment, by setting at least one intermediate guide post between the first guide post 220 and the second guide post 230, the length of each guide post segment can be reduced, so that the length of each guide post segment does not exceed the length of the second guide post 230. During the lifting process of the air spring 100, other guide posts outside the second guide post 230 can be compressed one by one into the second guide post 230, thereby better achieving the guiding and positioning of the air spring 100.
[0069] Specifically, the intermediate guide post in this embodiment includes a third guide post 240 and a fourth guide post 250. The third guide post 240 is sleeved on the first guide post 220, and the first guide post 220 is movable relative to the third guide post 240. The fourth guide post 250 is sleeved on the third guide post 240, and the third guide post 240 is movable relative to the fourth guide post 250. The second guide post 230 is sleeved on the fourth guide post 250, and the fourth guide post 250 is movable relative to the second guide post 230. Exemplarily, this is to ensure smooth sliding between adjacent guide posts and to limit circumferential rotation during assembly. In this embodiment, a third protrusion 241 is provided on the third guide post 240, and a guide groove is formed within the third protrusion 241. The guide groove includes an opening facing the first guide post 220 and a stop portion opposite to the opening. The first protrusion 221 can pass through the opening into the guide groove, and the stop portion can abut against the first protrusion 221, thereby limiting the length of the first guide post 220 sliding into the third guide post 240. Similarly, a fourth protrusion 251 is provided on the fourth guide post 250, and a guide groove is formed within the fourth protrusion 251. The guide groove includes an opening facing the third guide post 240 and a stop portion opposite to the opening. The third protrusion 241 can pass through the opening into the guide groove, and the stop portion can abut against the third protrusion 241, thereby limiting the length of the third guide post 240 sliding into the fourth guide post 250. The guide groove formed within the second protrusion 231 can correspondingly limit the length of the fourth guide post 250 sliding into the second guide post 230.
[0070] In this embodiment, by setting a third guide post 240 and a fourth guide post 250 between the first guide post 220 and the second guide post 230, the lengths of the first guide post 220, the third guide post 240, and the fourth guide post 250 can all be less than the length of the second guide post 230. During the lifting process of the air spring 100, the first guide post 220, the third guide post 240, and the fourth guide post 250 can be compressed one by one into the second guide post 230, thereby better guiding and positioning the air spring 100.
[0071] It is understood that the number of the first groove 111, the second groove 121, the first protrusion 221, and the second protrusion 231 in the embodiments of this application can be set as needed, for example, there can be two or three. The material of the guide pad 200 can be selected as needed, for example, it can be metal, high-hardness rubber, or plastic.

[0073] The suspension system of this application embodiment adopts the above-mentioned suspension positioning components, which helps to improve the positioning accuracy during air spring assembly and increase the success rate of air spring and guide bushing assembly.

[0075] The vehicle in this embodiment of the application uses the above-described suspension system, which helps to improve the positioning accuracy during air spring assembly and increase the success rate of air spring and guide bushing assembly.
