Description

Technical Field

[0001] The invention relates to the technical field of automobile suspension, and in particular to a gas spring and damper assembly, automobile suspension and vehicle. Background Art

[0002] The air spring is a sealed container filled with compressed air, which uses the compressibility of gas to achieve its elastic effect. The air spring has ideal nonlinear elastic characteristics. After the height adjustment device is installed, the height of the vehicle body does not change with the increase or decrease of the load. The spring stiffness can be designed to be lower, and the ride comfort is good.

[0003] Air springs are usually used with shock absorbers. The current mainstream product on the market is a double wishbone suspension equipped with air springs. However, this structure requires more parts, which is not conducive to the cost control of the car. The McPherson air spring is a type of air spring that can automatically adjust the shock absorption force according to the road conditions, so that the wheels always maintain good contact with the ground, thereby improving grip and steering accuracy. In addition, the McPherson air spring can also effectively absorb the vibration and noise of the road, so that the passengers in the car can feel a smoother and quieter driving experience.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

[0026] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0028] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element.

[0029] CN114302816B (hereinafter referred to as Patent 1) discloses a gas spring and damper assembly. As can be seen from Figure 7 of the specification, the top of the gas spring assembly 300 is sealed and arranged above the elastic element 244 through a seal 448, and the seal 448 is sealed and connected to the connector housing 410 and the sealing cover 442. In this way, the installation space of the vehicle body structure in the axial direction of the damper rod will be compressed, resulting in the horizontal arrangement of elements such as bearings that can make the gas spring assembly 300 and the vehicle body structure rotate relative to each other, occupying the horizontal space, which is not conducive to the expansion of the cabin space; at the same time, the top of the gas spring assembly 300 is raised, and it will be constrained by other parts during installation. For example, it is necessary to add a sealing cover 442, and after the sealing cover 442 is added, the seal 448 will be sealed and connected to the connector housing 410 and the sealing cover 442, making it difficult to fix it, and then it is necessary to add additional elements (such as the first support assembly 414 in Patent 1) to reinforce the gas spring assembly, which will undoubtedly increase the structural complexity and cost of the gas spring and damper assembly.

[0030] The present application provides a gas spring and damper assembly, wherein the top of the gas spring is arranged between the first elastic member and the damper housing along the axial direction of the damper rod, so that the sealing position of the top of the gas spring and the damper rod can be moved downward, which is beneficial for the vehicle body structure to be directly and firmly connected to the damper rod as a whole through the first coupling part, and the gas spring is sealed and connected to the damper rod, thereby reducing the coupling parts between the vehicle body structure and the damper rod in the McPherson air spring, reducing the structural complexity and cost, and at the same time, it is also beneficial to reduce the space occupied by the assembly and facilitate the space expansion of the cabin.

[0031] like Figures 1 to 3As shown, the embodiment of the present application provides a gas spring and damper assembly 10, which is arranged between a vehicle body structure and a wheel, and includes: a damper 110, having a damper housing 111, and a damper rod 112 with one end arranged in the damper housing 111 and the other end extending out of the damper housing 111; a mounting assembly 120, having a first coupling portion 121 coupled to a portion of the damper rod 112 extending out of the damper housing 111, and a second coupling portion 122 coupled to the vehicle body structure, the first coupling portion 121 including a first outer fixing member 1211, a first inner fixing member 1212 and a second fixing member 1211 arranged opposite to each other. and a first elastic member 1213 between the first inner fixing member 1212; and a gas spring 130, which is rotatably connected to the mounting assembly 120; wherein the gas spring 130 has a bladder skin 131, which is arranged around the damper rod 112 and extends longitudinally between the opposite first end 1311 and the second end 1312 to form a spring chamber 1310, and the central axis AX2 of the bladder skin is not coaxial with the central axis AX1 of the damper rod 112; and, the top of the gas spring 130 is sealed and connected to the damper rod 112, and the top of the gas spring 130 is arranged between the first elastic member 1213 and the damper housing 111 along the axial direction of the damper rod 112.

[0032] Since the central axis AX2 of the bladder skin in the McPherson air spring is not coaxial with the central axis AX1 of the damper rod 112, when the vehicle body structure is adapted to the road conditions for shock absorption, the vehicle body structure usually undergoes a large twist relative to the gas spring 130, so that the mounting assembly 120 relatively fixed to the vehicle body structure needs to be rotatably connected to the gas spring 130 to release the twisting angle; at the same time, by sealing the connection position between the gas spring 130 and the damper rod 112, gas outflow can be avoided, thereby ensuring the shock absorption effect; further, by sealing the top of the gas spring 130 with the damper housing 112 and the sealing position (such as Figure 2 The position indicated by the dotted line P shown in the figure) is located between the first elastic member 1213 and the damper housing 111. In this way, the installation space at the top of the gas spring 130 for connecting the damper 110 to the vehicle body structure can be increased, thereby facilitating the arrangement of other parts in the axial direction of the damper rod 112, reducing the lateral space occupied by the component 10, facilitating the expansion of the vehicle cabin space, and also helping to reduce the coupling parts between the component 10 and the vehicle body structure, thereby reducing the structural complexity and cost of the suspension.

[0033] Optionally, the angle between the central axis AX2 of the bladder skin in the McPherson air spring and the central axis AX1 of the damper rod 112 is less than or equal to 45°, for example, the angle may be one of 0.1°, 1°, 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, and 45°.

[0034] Optionally, the gas spring 130 can be rotatably connected to the mounting assembly 120 through structures such as bearings and rotating shafts. Exemplarily, when a bearing is used, since the top of the gas spring 130 is disposed between the first elastic member 1213 and the damper housing 111, the top of the gas spring 130 can be rotatably connected to the mounting assembly 120 through a bearing in the axial direction of the damper rod 112, and the top of the gas spring 130 is already sealed and connected to the damper rod 112, so there is no need to set other components to reinforce the gas spring 130.

[0035] Optionally, the component 10 may also be provided with a locking structure to lock the first coupling portion 121 and the damper rod 112, so that the damper 110 is relatively fixed to the vehicle body structure. At this time, when the mounting component 120 rotates relative to the gas spring 130, the damper rod 112 will also rotate relative to the gas spring 130, so that an element capable of absorbing the displacement of the damper rod 112 may be provided between the gas spring 130 and the damper rod 112 to reduce the interference between the damper rod 112 and the gas spring 130, thereby ensuring the service life of the component 10.

[0036] It should be pointed out that, in a conventional double wishbone air spring, the central axis of the damper rod is coaxial with the central axis of the bladder skin, so that during the driving of the vehicle, the air spring and the vehicle body structure basically do not undergo relative torsion (even if a very small torsion occurs, it can be absorbed by the bladder skin itself), so the coupling position between the air spring and the damper rod can be sealed by static sealing. However, the component 10 of the present application belongs to a McPherson air spring, and the central axis AX1 of the damper rod 112 is not coaxial with the central axis AX2 of the bladder skin 131, so during the driving of the vehicle, the air spring 130 and the vehicle body structure need to be able to undergo relative torsion, so the coupling position between the air spring 130 and the damper rod 112 cannot be sealed by static sealing, but needs to be sealed by dynamic sealing.

[0037] In some embodiments, see Figure 2 , the assembly 10 also includes a bearing assembly 140 disposed between the top of the gas spring 130 and the first coupling portion 121 along the axial direction of the damper rod 112; the bearing assembly 140 includes a first support ring 141 coupled to the gas spring 130, a second support ring 142 coupled to the mounting assembly 120, and a sliding element (not shown) disposed between the first support ring 141 and the second support ring 142, the sliding element abutting against at least one of the first support ring 141 and the second support ring 142 for sliding connection, so that the first support ring 141 and the second support ring 142 can rotate relative to each other around the central axis AX1 of the damper rod 112. Optionally, the first support ring 141 and the second support ring 142 are respectively located at different axial height positions of the damper rod 112, that is, as shown in FIG. Figure 2As shown, the first support ring 141 is located above the second support ring 142. With this arrangement, the bearing assembly 140 can be removed from the damping force transmission chain from the damper rod 112 to the vehicle body structure, thereby extending the service life of the bearing assembly 140 to a certain extent.

[0038] In some embodiments, the first support ring 141 includes a first support surface 1411 extending along the axial direction of the damper rod 112, and a second support surface 1412 connected to the first support surface 1411 and extending in a direction close to or away from the damper rod 112; the top of the gas spring 130 abuts the first support surface 1411 and the second support surface 1412. By setting the first support surface 1411 extending along the axial direction, the bearing assembly 140 can offset the lateral force received by the vehicle during driving, thereby preventing the generated lateral force from causing damage to the assembly 10. Optionally, the second support surface 1412 can be along a direction perpendicular to the axis AX1, so that even if the bearing assembly 140 is worn during use and a gap is generated, the gas spring 130 can be kept in abutment with the bearing assembly 140 through the inflation operation of the gas spring 130 itself, thereby avoiding the generation of abnormal noise.

[0039] In some embodiments, Figure 3 As shown, the first outer fixing member 1211 is coupled with the second support ring 142, and at least a portion of the first outer fixing member 1211 is located between the bottom of the first elastic member 1213 and the second support ring 142, and the first inner fixing member 1212 is coupled with the damper rod 112. Such a configuration is, on the one hand, conducive to fixing the mounting assembly 120 with the damper rod 112, and on the other hand, conducive to absorbing the rotation of the damper rod 112 by the first elastic member 1213, so that the first coupling portion 121 as a whole can follow the damper rod 112 without relative displacement, thereby ensuring the fixed connection between the mounting assembly 120 and the damper rod 112.

[0040] Optionally, the material of the first elastic member 1213 may be any combination of one or more of natural rubber, synthetic rubber (eg, EPDM, polychloroprene) and / or thermoplastic elastomer (eg, thermoplastic polyurethane, thermoplastic vulcanized rubber, thermoplastic polyolefin).

[0041] In some embodiments, Figure 4As shown, the gas spring 130 further includes: an upper seat 132, which is disposed on the top of the bladder skin 131 and is provided with a through hole for the damper rod 112 to pass through; a sealing assembly 133, which is disposed in the through hole and supported by the upper seat 132, and is configured to be sealed and connected to the upper seat 132 and the damper rod 112. In some embodiments, the upper seat 132 abuts against the first support surface 1411 and the second support surface 1412. Through the above arrangement, the sealing position of the gas spring 130 can be moved downward, which is conducive to reducing the number of bearings and mounting parts in the McPherson air spring, reducing costs and simplifying the structure while ensuring performance.

[0042] Optionally, the sealing assembly 133 includes a first sealing member 1331 sealedly connected to the damper rod 112 and a second sealing member 1332 sealedly connected to the upper seat 132, wherein the first sealing member 1331 is configured to form a dynamic seal with the damper rod 112, and the second sealing member 1332 is configured to form a static seal with the upper seat 132; or, the first sealing member 1331 is configured to form a static seal with the damper rod 112, and the second sealing member 1332 is configured to form a dynamic seal with the upper seat. Through the above arrangement, the damper rod 112 can effectively ensure the sealing between the gas spring 130 and the damper rod 112 while rotating relative to the upper seat 132, and the reliability of the sealing can be ensured by the cooperation of the dynamic and static seals.

[0043] Optionally, the first sealing member 1331 includes a first fixing member 13311 and a first sealing ring 13312 disposed on the side of the first fixing member 13311 facing the damper rod 112, the first sealing ring 13312 abuts against the first fixing member 13311 and the damper rod 112 at least in the radial direction of the through hole; the second sealing member 1332 includes a second fixing member 13321 and a second sealing ring 13322 disposed on the side of the second fixing member 13321 facing the upper seat 132, the second sealing ring 13322 abuts against the upper seat 132 and the second fixing member 13321 at least in the radial direction of the through hole. The first sealing ring 13312 can be disposed in the groove formed in the first fixing member 13311 to form a dynamic seal (or static seal) with the damper rod 112, and the second sealing ring 13322 can be disposed in the groove formed in the second fixing member 13321 to form a static seal (or dynamic seal) with the upper seat 132.

[0044] Optionally, a second elastic member 1333 is provided between the first sealing member 1331 and the second sealing member 1332 for absorbing the displacement of the damper rod 112 relative to the upper seat 132. Optionally, the material of the second elastic member 1333 may be any combination of one or more of natural rubber, synthetic rubber (e.g., EPDM, polychloroprene) and / or thermoplastic elastomer (e.g., thermoplastic polyurethane, thermoplastic vulcanized rubber, thermoplastic polyolefin).

[0045] The embodiment of the present application also provides a vehicle suspension, comprising the gas spring and damper assembly as described in the above embodiment. The above vehicle suspension is conducive to reducing the number of parts used while ensuring the relative rotation of the gas spring and the vehicle body structure, thereby reducing the cost and space occupied by the vehicle suspension.

The above vehicle, by providing the above automobile suspension, is conducive to widening the internal space of the cabin while ensuring the buffering performance of the suspension, and reducing the manufacturing cost of the vehicle.
