Description

Technical Field

[0001] The invention relates to the technical field of air springs, and in particular to a mounting structure, an air spring and an automobile suspension. Background Art

[0002] At present, the rear air spring bearing seat positioning method on the market adopts the rear pin type, that is, after the bearing seat is assembled, the fixing pin is inserted into the positioning hole separately for rotation positioning, to ensure the correct position of the bearing seat during transportation and assembly, and to accurately match the vehicle body mounting hole during assembly, and remove the positioning pin at a special station after the vehicle assembly is completed.

[0003] However, this method will increase the requirements for assembly and disassembly. If the positioning pins are omitted, the torsional angle of the vehicle suspension cannot be released and can only be directly borne by the bladder skin, causing the bladder skin to fatigue and damage quickly. Summary of the invention

[0004] Based on this, the present invention aims to provide an improved mounting structure, an air spring and a vehicle suspension to solve at least one of the above problems.

[0005] In a first aspect, the present application provides a mounting structure for an air spring, the mounting structure comprising a bearing seat, a piston, and a bearing arranged between the bearing seat and the piston, the bearing seat and the piston being configured to move relative to each other under the action of an external force and change the coupling state so as to be in a first coupling state and a second coupling state in sequence; wherein, when the bearing seat and the piston are in the first coupling state, the bearing seat and the piston are limited to each other; when the bearing seat and the piston are in the second coupling state, the bearing seat and the piston are released from the limit and are rotationally connected to the piston through the bearing.

[0006] The above-mentioned installation structure changes the coupling state between the bearing seat and the piston through the relative movement between the bearing seat and the piston, so that the bearing seat and the piston can limit each other when the first coupling state is satisfied, thereby limiting the rotation of the bearing seat, and meeting the limiting requirements for the bearing seat and the piston during transportation, handling and assembly of the air spring; and, when the bearing seat and the piston meet the second coupling state, the bearing seat can rotate relative to the piston through the bearing, thereby facilitating the release of the torsion angle generated during the suspension movement through the rotation of the bearing, without the need for additional disassembly action, thereby avoiding the impact on the life of the bladder skin due to the inability to release the torsion angle due to the omission of disassembly of the locating pin.

[0007] In one of the embodiments, during the process in which the bearing seat and the piston are successively in the first coupling state and the second coupling state, the bearing seat and the piston are configured to move toward each other along the height direction of the mounting structure under the action of an external force.

[0008] In one embodiment, the bearing seat is configured to move toward the piston under the action of a first external force until the bearing seat and the piston are in the first coupling state; the piston is configured to move toward the bearing seat under the action of a second external force until the bearing seat and the piston are in the second coupling state.

[0009] In one embodiment, the bearing seat has a main body and at least one first coupling part arranged along the circumference of the main body, and the piston has at least one second coupling part corresponding to the first coupling part one by one; when the bearing seat and the piston are in the first coupling state, the first coupling part is coupled with the limiting part of the second coupling part; in the process of switching the bearing seat and the piston from the first coupling state to the second coupling state, the first coupling part disengages from and moves away from the limiting part.

[0010] In one embodiment, the first coupling part includes a limit block connected to the main body, and the limit part includes a limit groove; when the first coupling part is coupled with the limit part, the limit block is engaged in the limit groove; when the first coupling part is disengaged from and moves away from the limit part, the limit block moves out of the limit groove and moves away from the limit groove.

[0011] In one of the embodiments, a first inclined surface is provided on a side of the limiting block facing the limiting groove, and a second inclined surface matching the first inclined surface is provided on at least one groove wall of the limiting groove facing the limiting block.

[0012] In one embodiment, the first coupling portion further includes a connecting member having one end connected to the main body and the other end connected to the limiting block, and a length of the connecting member in the height direction of the mounting structure is greater than or equal to a length of the limiting portion in the height direction of the mounting structure.

[0013] In a second aspect, the present application provides an installation method of the installation structure as described in any of the preceding embodiments, comprising: aligning the bearing seat with the piston; moving the bearing seat toward the piston until the bearing seat and the piston are in the first coupling state; inflating the air spring after the entire vehicle is assembled to move the piston toward the bearing seat until the bearing seat and the piston are in the second coupling state.

[0014] The above-mentioned installation method limits the rotation of the bearing seat by allowing the bearing seat and the piston to limit each other when they satisfy the first coupling state, thereby meeting the limiting requirements for the bearing seat and the piston during transportation, handling and assembly of the air spring; further, by allowing the bearing seat to rotate relative to the piston when the bearing seat and the piston satisfy the second coupling state, it is beneficial to release the torsion angle generated during the suspension movement through bearing rotation, without the need for additional disassembly action, thereby avoiding the impact on the life of the air spring due to the inability to release the torsion angle due to omitted disassembly of the locating pin.

[0015] In a third aspect, the present application provides an air spring, comprising a mounting structure as described in any of the foregoing embodiments.

[0016] The above-mentioned air spring can not only meet the limiting requirements for the bearing seat and the piston during transportation, handling and assembly, but also release the torsion angle generated during the suspension movement through bearing rotation during subsequent use, without the need for additional disassembly, thereby avoiding the impact on the life of the air spring due to the inability to release the torsion angle due to omitted disassembly of the locating pin.

[0017] In a fourth aspect, the present application provides a vehicle suspension, comprising an air spring as described in the foregoing embodiment.

[0018] The above-mentioned automobile suspension can release the torsion angle generated by the rotation of the bearing during its movement without additional disassembly, thereby avoiding the impact on the life of the bladder skin caused by the failure to release the torsion angle due to the omission of disassembly of the positioning pin.

DETAILED DESCRIPTION

[0021] 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. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0022] In the description of the present invention, it is to 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”, etc., indicating orientations or positional relationships are 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 device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0023] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. 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.

[0024] 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. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0025] At present, the rear air spring bearing seat positioning method on the market adopts the rear pin type, such as Figure 1As shown, after the bearing seat 110' is assembled, the fixing pin 130' is separately inserted into the positioning holes of the bearing seat 110' and the piston 140' for rotational positioning, so as to ensure that the relative position of the bearing seat 110' and the piston 140' is correct during the transportation and assembly process, and that it can accurately match the mounting hole of the vehicle body during the assembly process. After the whole vehicle is assembled, the positioning pin needs to be removed at a special station. This method adds additional assembly and disassembly requirements. If the disassembly is omitted, the life of the bladder skin will be shortened, thereby affecting the use of the vehicle suspension.

[0026] Based on the above problems, the present application provides an installation structure, which utilizes the relative movement between the bearing seat and the piston to change the coupling state between the bearing seat and the piston, so that when the bearing seat and the piston meet the first coupling state, the bearing seat and the piston can limit each other, thereby limiting the rotation of the bearing seat, and meeting the limiting requirements of the bearing seat and the piston during transportation, handling, and assembly of the air spring; and, when the bearing seat and the piston meet the second coupling state, the bearing seat can rotate relative to the piston, which is conducive to releasing the large torsional angle generated by the bladder skin during the suspension movement through the rotation of the bearing, without the need for additional disassembly action, thereby avoiding the inability to release the torsional angle due to the omission of disassembly of the locating pin, thereby affecting the life of the bladder skin. like Figures 2 to 5 As shown, an embodiment of the present application provides a mounting structure, which is applied to an air spring, and the mounting structure includes a bearing seat 110, a piston 140, and a bearing (not shown) arranged between the bearing seat 110 and the piston 140. The bearing seat 110 and the piston 140 are configured to move relative to each other under the action of an external force to change the coupling state so as to be in a first coupling state and a second coupling state in sequence; wherein, when the bearing seat 110 and the piston 140 are in the first coupling state, the bearing seat 110 and the piston 140 are limited to each other; when the bearing seat 110 and the piston 140 are in the second coupling state, the bearing seat 110 and the piston 140 are released from the limit and can rotate relative to the piston 140.

[0027] like Figure 2 As shown, a plurality of connectors 150 are provided along the axial direction of the bearing seat 110, and the conventional fixing method is usually to limit the bearing seat 110 by passing a positioning pin through a positioning hole on the connector 150. Optionally, the embodiment of the present application can further modify the connector 150 so that the modified connector 150 can automatically release the limitation on the bearing seat 110 through the subsequent inflation step of the air spring, thereby avoiding the omission of the positioning pin from being disassembled; optionally, the connector 150 used for modification can be one or more, for example, two connectors symmetrical about the plane where the axis of the bearing seat 110 is located. In other embodiments, the above-mentioned coupling state can also be achieved by adding one or more coupling components, which is not limited by the present application.

[0028] Illustratively, before being in the first coupling state, the bearing seat 110 and the piston 140 can be in a coupled state or an uncoupled state. Through relative movement, the bearing seat 110 and the piston 140 can interact with each other to be in the first coupling state and then in the second coupling state.

[0029] Exemplarily, "mutual limitation" may mean that the bearing seat 110 and the piston 140 are fixed to each other; in other embodiments, "mutual limitation" may also mean that the bearing seat 110 and the piston 140 leave a small amount of displacement space (such as a gap) for the bearing seat 110 and the piston 140 to move, as long as the two have not moved out of the predetermined area.

[0030] For example, “the bearing seat 110 can rotate relative to the piston 140” can be represented by Figures 2 to 6 In the perspective shown, the bearing seat 110 can rotate horizontally relative to the piston 140. Optionally, the bearing seat 110 can be rotatably connected to the piston 140 via a bearing, so as to achieve horizontal rotation of the bearing seat 110 relative to the piston 140.

[0031] Illustratively, in the process of switching the coupling state of the bearing seat 110 and the piston 140 from the first coupling state to the second coupling state, the interaction force between the bearing seat 110 and the piston 140 gradually weakens, so that the mutual limiting effect between the two also gradually weakens, and at a certain time point the mutual limiting effect disappears, and the bearing seat 110 can rotate freely relative to the piston 140.

[0032] Optionally, during the process that the bearing seat 110 and the piston 140 are in the first coupling state and the second coupling state in sequence, the bearing seat 110 and the piston 140 are configured to move along the height direction D (such as Figure 3 ) move toward each other. Here, "move toward each other" means that the bearing seat 110 can move toward the piston 140 under the action of a first external force (until the bearing seat 110 and the piston 140 are in a first coupling state), or the piston 140 can move toward the bearing seat 110 under the action of a second external force (until the bearing seat 110 and the piston 140 are in a second coupling state). Optionally, the first external force can be applied to the bearing seat 110 through an external device, which is conducive to controlling the pressure. In addition, the bearing seat 110 can also be moved slowly by the first external force to avoid large friction during the movement and affect the structural performance. Optionally, the second external force can be formed by the subsequent inflation action of the air spring to move the piston 140 toward the bearing seat 110, so as to change the coupling state of the bearing seat 110 and the piston 140, thereby releasing the limit of the bearing seat 110.

[0033] Exemplarily, before the bearing seat 110 and the piston 140 are in the first coupling state, as shown in FIG. Figure 2 and Figure 3 As shown, the bearing seat 110 is in a free state. Optionally, in order to facilitate subsequent docking, the coupling portion of the bearing seat 110 and the coupling portion of the piston 140 can be aligned before relative movement.

[0034] In some embodiments of the present application, Figures 3 to 5 As shown, the bearing seat 110 has a main body 111 and at least one first coupling part 112 arranged along the circumference of the main body 111, and the piston 140 has at least one second coupling part 141 corresponding to the first coupling part 112; when the bearing seat 110 and the piston 140 are in the first coupling state, the first coupling part 112 is coupled with the limiting part of the second coupling part 141; when the bearing seat 110 and the piston 140 are switched from the first coupling state to the second coupling state, the first coupling part 112 is disengaged from and moves away from the limiting part.

[0035] Optional, such as Figures 3 to 5 As shown, the first coupling portion 112 can be symmetrically arranged on both sides of the bearing seat 110, and the second coupling portion 141 corresponds to the first coupling portion 112 one by one. Figure 3 As shown, before the bearing seat 110 and the piston 140 are in the first coupling state, the first coupling portion 112 may be slightly higher than the second coupling portion 141 and aligned with the second coupling portion 141. Optionally, as Figure 4 As shown, when the bearing seat 110 and the piston 140 are in the first coupling state, the first coupling portion 112 can be coupled with the limiting portion of the second coupling portion 141 to limit the bearing seat 110 and the piston to each other through the interaction between the two. Figure 5 As shown, during the process of the bearing seat 110 and the piston 140 switching from the first coupling state to the second coupling state, the air spring is inflated, and an upward pressure is generated inside, the piston 140 is lifted and moves upward, thereby driving the limiting part to move upward, so that the first coupling part 112 is disengaged and away from the limiting part; optionally, as Figure 5 As shown, when the bearing seat 110 and the piston 140 are in the second coupling state, there is a gap between the coupling part (such as the limiting block 1122) of the first coupling portion 112 and the limiting part.

[0036] In some embodiments of the present application, Figures 3 to 5 As shown, the first coupling part 112 includes a limit block 1122 connected to the main body 111, and the limit part includes a limit groove 1411; when the first coupling part 112 is coupled with the limit part 1411, the limit block 1122 is clamped in the limit groove 1411; when the first coupling part 112 is disengaged from and away from the limit part, the limit block 1122 moves out of the limit groove 1411 and away from the limit groove 1411.

[0037] Optional, such as Figure 6As shown, the first inclined surface 11221 is provided on one side of the limiting block 1122 facing the limiting groove 1411, and the second inclined surface 14111 cooperating with the first inclined surface 11221 is provided on at least one groove wall of the limiting groove 1411 facing the limiting block 1122. In this way, in the process of the limiting block 1122 disengaging from the limiting portion (such as the limiting groove 1411), the limiting block 1122 can be slightly enclosed to disengage from the limiting groove 1411, and it is also beneficial to reduce the resistance during the relative movement of the bearing seat 110 and the piston 140. Optionally, the first inclined surface 11221 and the second inclined surface 14111 are parallel and can be obtained by rotating the horizontal plane clockwise at an acute angle. Optionally, the two opposite groove walls of the limiting groove 1411 can be provided with the second inclined surface 14111, so that it is not only beneficial to facilitate the limiting block 1122 to be clamped to the limiting groove 1411, but also beneficial to the limiting block 1122 to be disengaged from the limiting groove 1411.

[0038] Optionally, the limiting portion may be composed of an upper groove wall (including wall thickness) of the limiting groove 1411 , the limiting groove 1411 , and a lower groove wall (including wall thickness) of the limiting groove.

[0039] In some embodiments of the present application, Figure 5 As shown, the first coupling portion 112 further includes a connecting member 1121 connected to the main body 111 at one end and connected to the stop block 1122 at the other end, and the length H1 of the connecting member 1121 in the height direction of the mounting structure 100 is greater than or equal to the length H2 of the stop portion in the height direction of the mounting structure 100. In this way, it is beneficial to ensure that during the relative movement of the bearing seat 110 and the piston 140, the stop portion will not interfere with the lower surface of the main body 111, thereby ensuring that when the bearing seat 110 and the piston 140 are in the second coupling state, the bearing seat 110 can maintain a free rotation state.

[0040] The present application also provides a method for installing the installation structure 100 as described in any of the above embodiments, including: S100, aligning the bearing seat 110 and the piston 140; S200, moving the bearing seat 110 toward the piston 140 until the bearing seat 110 and the piston 140 are in a first coupling state; S300, after the whole vehicle is assembled, the air spring is inflated to move the piston 140 toward the bearing seat 110 until the bearing seat 110 and the piston 140 are in the second coupling state.

[0041] The above-mentioned installation method limits the rotation of the bearing seat 110 by limiting the mutual position of the bearing seat 110 and the piston 140 when the bearing seat 110 and the piston 140 satisfy the first coupling state, thereby meeting the limiting requirements for the bearing seat 110 and the piston 140 during transportation, handling and assembly of the air spring; further, by allowing the bearing seat 110 to rotate relative to the piston 140 when the bearing seat 110 and the piston 140 satisfy the second coupling state, it is beneficial to release the large torsional angle generated by the bladder skin during the suspension movement through bearing rotation, without the need for additional disassembly action, thereby avoiding the impact on the life of the bladder skin due to the inability to release the torsional angle due to the omission of disassembly of the locating pin.

[0042] Exemplarily, the bearing seat 110 has a first coupling portion 112, and the piston has a second coupling portion 141. To facilitate subsequent docking, the first coupling portion 112 of the bearing seat 110 and the second coupling portion 141 of the piston 140 may be aligned before relative movement.

[0043] An embodiment of the present application also provides an air spring, comprising a mounting structure as described in any of the above embodiments.

[0044] The above-mentioned air spring can not only meet the limiting requirements for the bearing seat and the piston during transportation, handling and assembly, but also release the torsion angle generated during the suspension movement through bearing rotation during subsequent use, without the need for additional disassembly, thereby avoiding the impact on the life of the air spring due to the inability to release the torsion angle due to omitted disassembly of the locating pin.

[0045] An embodiment of the present application also provides a vehicle suspension, comprising the air spring as described in the above embodiment.

[0046] The above-mentioned automobile suspension can release the torsion angle generated by the rotation of the bearing during its movement without additional disassembly, thereby avoiding the impact on the life of the bladder skin caused by the failure to release the torsion angle due to the omission of disassembly of the positioning pin.

[0047] It should be noted that the numbers representing quantities or properties used to describe and claim certain embodiments of the present application should be understood to be modified by the terms "roughly", "about", "approximately" or "substantially" in some cases. For example, unless otherwise specified, "roughly", "about", "approximately" or "substantially" can indicate a ±20% variation of the value described. Accordingly, in some embodiments, the numerical parameters used in the specification and claims are approximate values, which may change according to the required features of individual embodiments. In some embodiments, the numerical parameters should take into account the specified significant digits and adopt the general method of retaining digits. Although the numerical domains and parameters used to confirm the breadth of their range in some embodiments of the present application are approximate values, in specific embodiments, the setting of such numerical values ​​is as accurate as possible within the feasible range.

[0048] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
