Description

Technical Field

[0001] This invention relates to the field of vehicle vibration damping technology, and in particular to a vibration damping structure and an active lateral stabilizer bar. Background Technology

[0002] When a vehicle experiences bumps or rolls, the active stabilizer bar generates a torque to resist the body roll, thus maintaining vehicle stability. Dampers are used in active stabilizers to buffer the gear output and the external environment during transmission, preventing gear wear and damage. Typically, damper rubber is selected with high hardness to ensure fatigue durability, resulting in high damping during deformation. However, the damper's stiffness and the magnitude of damping during deformation cannot be adjusted, failing to meet different target stiffness requirements. Summary of the Invention

The first connecting hole is disposed facing the concave side, and the extension portion is connected to the convex side. The second deformation hole is formed as a strip-shaped hole extending in a direction perpendicular to the first direction.

[0009] Preferably, the direction perpendicular to the first direction includes a second direction, a third direction, a fourth direction, and a fifth direction, wherein the second direction is perpendicular to the third direction, the fourth direction is perpendicular to the fifth direction, the angle between the fourth direction and the second direction is 45°, a plurality of first deformation holes are arranged at intervals along the second direction and the third direction, and a plurality of second deformation holes are arranged at intervals along the fourth direction and the fifth direction.

[0010] Preferably, the first connector is interference-fitted with the first connecting hole, and the second connector is interference-fitted with the second connecting hole; And / or, the number of the first connecting holes on the damping member is the same as the number of the second connecting holes.

[0011] Preferably, both the first connector and the second connector have protruding limiting bosses on their circumferential sidewalls.

[0013] A second aspect of the present invention provides an active lateral stabilizer bar, comprising the vibration damping structure described in any of the above technical solutions.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: In the vibration damping structure of the present invention, the vibration damping component includes a plurality of damping elements arranged along a first direction. Each damping element has a first hole group and a second hole group. The first hole group includes a plurality of deformation holes arranged at intervals along the circumference of the damping element. The second hole group includes a first connecting hole and a second connecting hole. The connecting component includes a first connecting member that mates with the first connecting hole and a second connecting member that mates with the second connecting hole. Two adjacent damping elements are connected by the same first connecting member or the same second connecting member, such that a damping element is connected to a damping element adjacent to it on one side of the first direction by the first connecting member, and a damping element is connected to a damping element adjacent to it on the other side of the first direction by the second connecting member. In this way, when the vibration damping structure rotates, the stress generated by the deformation of each damping element can work together with the adjacent damping elements to generate a torsional force, thereby generating resistance in the direction of rotation and playing a damping role. Because each damping component has deformation holes, the damping is reduced during deformation. Therefore, the damping magnitude during rotation of the damping structure can be controlled by adjusting the shape and size of the deformation holes and / or the number of the first and second connectors in the damping components and connecting assemblies, according to the target stiffness requirements of the damping structure. Furthermore, the damping structure of this application does not require vulcanization injection molding of the metal; it can be directly assembled with the connecting assemblies after the damping components are manufactured, reducing manufacturing processes, facilitating product production, and meeting the needs of mass production and industry applications of fully automated active lateral stabilizer bars.

[0028] According to a first aspect of the present invention, a vibration damping structure is provided, which includes a vibration damping component 1 and a connecting component 2.

[0029] The specific structure of the above-mentioned components according to the vibration damping structure of this embodiment will be described below.

[0030] In this embodiment, as Figure 1 and Figure 2 As shown, the vibration damping assembly 1 includes multiple damping elements 10 arranged along the first direction D1, i.e., the number of damping elements 10 is ≥2. The damping elements 10 can be rubber blocks, such as disc-shaped rubber blocks. Each damping element 10 has a first group of holes 11 and a second group of holes 12. The number of damping elements 10 in the vibration damping assembly 1 can be even, such as 4, 6, etc., or it can be odd.

[0031] Specifically, such as Figure 3 and Figure 4 As shown, the first hole group 11 includes a plurality of deformation holes arranged at intervals along the circumference of the damping member 10. The deformation holes reduce the damping of the damping member 10 during rotation. In this embodiment, the damping magnitude during rotation can be controlled by adjusting the shape and / or size of the deformation holes according to the target stiffness requirements of the damping structure. Preferably, the deformation holes are through holes, for example, through holes penetrating the damping member along the first direction D1.

[0032] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the second hole group 12 includes a first connecting hole 121 and a second connecting hole 122, which are through holes penetrating the vibration damper. The connecting assembly 2 includes a first connecting member 21 that mates with the first connecting hole 121 and a second connecting member 22 that mates with the second connecting hole 122. The first connecting member 21 and the second connecting member 22 can be formed into rod-shaped, column-shaped, or other structures, and are preferably made of metal, so that the first connecting member 21 can extend into the first connecting hole 121 and the second connecting member 22 can extend into the second connecting hole 122.

[0033] Specifically, in this embodiment, two adjacent damping members 10 are connected by the same first connector 21 or the same second connector 22, such that the damping member 10 is connected to the damping member 10 adjacent to it on one side of the first direction D1 by the first connector 21, and the damping member 10 is connected to the damping member 10 adjacent to it on the other side of the first direction D1 by the second connector 22. That is, the damping member 10 is connected to the damping members 10 on both sides of the first direction D1 by the first connector 21 and the second connector 22 respectively. In this way, when the damping structure rotates, the stress generated by the deformation of each damping member can work together with the adjacent damping members to generate torsional force, thereby generating resistance in the direction of rotation, so as to play a damping role.

[0034] In this invention, each damping element 10 has deformation holes, which reduces the damping of each damping element 10 compared to rubber without holes when it deforms. Each pair of adjacent damping elements 10 is connected by a first connector 21 or a second connector 22 to form a combination. When the damping structure is torsional, each damping element 10 rotates, and the internal stress from the deformation of each damping element 10 provides damping. Furthermore, the deformation of each element can be transferred to the next damping element 10 through the connecting first connector 21 or second connector 22, and so on, thus achieving a damping effect throughout the entire damping structure.

[0035] In this embodiment, the damping magnitude generated during the rotation of the vibration damping structure can be controlled by adjusting the shape and size of the deformation hole, the number and size of the damping elements 10 in the vibration damping assembly 1, and / or the number of the first connector 21 and the second connector 22 in the connecting assembly 2, according to the target stiffness requirements of the vibration damping structure.

[0036] Furthermore, the damping structure does not require vulcanization injection molding of the metal and can be directly assembled with the connecting component 2 after the damping component 10 is produced, reducing manufacturing processes, facilitating product production, and meeting the needs of mass production and industry applications of fully automated active lateral stabilizer bars.

[0037] In this embodiment, the first direction D1 is the extension direction of the axis of rotation of the damping structure. Preferably, the projections of the first hole group 11 and the second hole group 12 on all damping members 10 in the direction perpendicular to the first direction D1 are the same.

[0038] Furthermore, in this embodiment, as Figure 3 and Figure 4 As shown, the damping member 10 is provided with a first connecting area 101 and a second connecting area 102. The first connecting area 101 is formed into an annular region, and the second connecting area 102 is located within the annular region of the first connecting area 101. A first connecting hole 121 is opened in the first connecting area 101, and a second connecting hole 122 is opened in the second connecting area 102. That is, the installation position of the first connecting member 21 on the damping member 10 is closer to the edge of the damping member 10 than the installation position of the second connecting member 22 on the damping member 10, so that the installation positions of the first connecting member 21 and the second connecting member 22 on the damping member 10 are different. In this way, different damping members 10 are arranged continuously, and are connected sequentially by the connection of the first connecting member 21 and the second connecting member 22 which are separated in a direction perpendicular to the first direction D1, so as to ensure that the deformation is continuous. Since the first connector 21 and the second connector 22 are arranged in the first direction D1 as close to the outer side, close to the inner side, close to the outer side, and close to the inner side respectively, each damping member 10 has a different rotation angle after being connected by the first connector 21 and the second connector 22, which in turn pulls and squeezes the damping member 10.

[0039] Furthermore, some of the multiple deformation holes are at least partially disposed on the inner side of the first connecting area 101, and some of the multiple deformation holes are at least partially disposed on the outer side of the second connecting area 102, so that deformation holes are disposed on the inner side of the first connecting hole 121 and on the outer side of the second connecting hole 122.

[0040] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the number of first connecting holes 121 on the damping member 10 is the same as the number of second connecting holes 122. For example, if there are four first connecting holes 121, there are also four second connecting holes 122. This ensures that the number of first connecting members 21 and second connecting members 22 installed on the damping member 10 is the same. The shape of the cross-section of the first connecting member 21 perpendicular to the first direction D1 is the same as the shape of the first connecting hole 121, and the shape of the cross-section of the second connecting member 22 perpendicular to the first direction D1 is the same as the shape of the second connecting hole 122. In this embodiment, the first connecting hole 121 and the second connecting hole 122 are circular. In other alternative embodiments, the shapes of the first connecting hole 121 and the second connecting hole 122 can be polygonal, etc.

[0041] In this embodiment, the first connector 21 is interference-fitted with the first connecting hole 121, and the second connector 22 is interference-fitted with the second connecting hole 122, thus realizing the transmission of force during torsion. In other alternative embodiments, the first connector 21 and the first connecting hole 121, and the second connector 22 and the second connecting hole 122 can also be assembled by means of bonding or other methods.

[0042] In this embodiment, as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, both the first connector 21 and the second connector 22 have protruding limiting bosses 20 on their circumferential sidewalls. The limiting bosses 20 can abut against the opposing surfaces of two adjacent damping members 10, so that the two adjacent damping members 10 are spaced apart in the first direction D1 to reduce damping. Specifically, the dimension of the limiting boss 20 on the first connector 21 in the direction perpendicular to the first direction D1 is greater than the diameter of the first connecting hole 121 in the direction perpendicular to the first direction D1, and the dimension of the limiting boss 20 on the second connector 22 in the direction perpendicular to the first direction D1 is greater than the diameter of the second connecting hole 122 in the direction perpendicular to the first direction D1. This ensures that the two adjacent damping members 10 are separated by the limiting bosses 20, preventing large frictional forces between the two adjacent damping members 10. Preferably, the limiting bosses 20 are formed into a ring structure to increase the contact area between the limiting bosses 20 and the surface of the damping member 10, ensuring the separation effect.

[0043] Furthermore, such as Figure 5 and Figure 6 As shown, the limiting boss 20 on the first connector 21 is disposed in the middle of the first connector 21 in the first direction D1, and the two ends of the first connector 21 in the first direction D1 are coplanar with the opposing surfaces of the two adjacent damping members 10; the limiting boss 20 on the second connector 22 is disposed in the middle of the second connector 22 in the first direction D1, and the two ends of the second connector 22 in the first direction D1 are coplanar with the opposing surfaces of the two adjacent damping members 10.

[0044] In a preferred embodiment, such as Figures 1 to 4 As shown, the deformation holes include a first deformation hole 111 and a second deformation hole 112. The first deformation hole 111 and the second deformation hole 112 have different shapes and / or sizes. The first deformation hole 111 and the second deformation hole 112 are arranged alternately and at equal intervals along the circumference of the damping member 10.

[0045] Preferably, at least two first deformation holes 111 and at least two second deformation holes 112 are provided. More preferably, the number of first connecting holes 121 is the same as the number of first deformation holes 111, and the number of second connecting holes 122 is the same as the number of second deformation holes 112.

[0046] Furthermore, such as Figure 3 and Figure 4 As shown, in the direction perpendicular to the first direction D1, that is, parallel to the plane perpendicular to the first direction D1, the first deformation hole 111 is located on the side of the first connecting hole 121 facing the center of the damping member 10, that is, the first deformation hole 111 is located on the side of the first connecting hole 121 facing away from the edge of the damping member 10, and the second deformation hole 112 is located on the side of the second connecting hole 122 facing the edge of the damping member 10, that is, the second deformation hole 112 is located on the side of the second connecting hole 122 facing away from the center of the damping member 10. In this way, different deformation holes are provided at the edge and center of the damping member 10.

[0047] Furthermore, such as Figure 3 and Figure 4 As shown, the first deformation hole 111 includes a bent portion 1111 and an extension portion 1112. The bent portion can be formed as an arc-shaped structure or a structure formed by bending a strip to form an angle. In a direction perpendicular to the first direction D1, one side of the bent portion 1111 is formed as a concave side and the other side is formed as a convex side. The first connecting hole 121 is disposed facing the concave side, and the extension portion 1112 is connected to the convex side. Preferably, the extension portion 1112 is formed as a strip-shaped structure extending in a direction perpendicular to the first direction D1. In this embodiment, the second deformation hole 112 is formed as a strip-shaped hole extending in a direction perpendicular to the first direction D1.

[0048] Furthermore, the directions perpendicular to the first direction D1 include the second direction D2, the third direction D3, the fourth direction D4, and the fifth direction D5. The second direction D2 is perpendicular to the third direction D3, and the fourth direction D4 is perpendicular to the fifth direction D5. The angle between the fourth direction D4 and the second direction D2 is 45°. This divides the damping element 10 into eight equal parts. Multiple first deformation holes 111 are arranged at intervals along the second direction D2 and the third direction D3. For example, two first deformation holes 111 are arranged opposite each other along the second direction D2, and two first deformation holes 111 are arranged opposite each other along the third direction D3. Multiple second deformation holes 112 are arranged at intervals along the fourth direction D4 and the fifth direction D5. For example, two second deformation holes 112 are arranged at intervals along the fourth direction D4 and the fifth direction D5. Two deformation holes 112 are arranged opposite each other along the fourth direction D4, and two second deformation holes 112 are arranged opposite each other along the fifth direction D5. In this way, when the first deformation hole 111 includes a bent portion 1111 and an extension portion 1112 and the second deformation hole 112 is formed as an elongated hole, the angle between the length direction of the extension portion 1112 on the first deformation hole 111 and the length direction of the second deformation hole 112 is 45°. In this way, by setting the shape of the deformation hole, it can be ensured that the damping generated by the damper 10 during rotation is linear. Furthermore, the deformation hole is set on the side of the connecting assembly 2 so that the damper 10 can generate deformation and linear damping along the X and Y directions of the line connecting the first direction D1 and the third direction D3.

[0049] In a preferred embodiment, the first direction D1 is the YX direction on the vehicle, i.e., the longitudinal and transverse directions of the vehicle; the second direction D2 is the Z direction on the vehicle, i.e., the height direction of the vehicle; the third direction D3 is the YX direction on the vehicle, i.e., the longitudinal and transverse directions of the vehicle; the angle between the fourth direction D4 and the second direction D2 and the third direction D3 is 45°; and the fourth direction D4 and the fifth direction D5 are perpendicularly arranged.

[0050] It should be noted that deformation and vibration will occur when transmitting torsional damping. The damping in the corresponding directions can be adjusted by designing the position, shape and / or size of the deformation holes on the second direction D2, the third direction D3, the fourth direction D4 and the fifth direction D5. This adjustment design can ensure that the damping structure transmits torque with smaller damping, reduced vibration and larger torsional stiffness in the first direction D1.

[0051] According to the vibration damping structure of the present invention, the vibration damping assembly 1 includes a plurality of damping elements 10 arranged along a first direction D1. Each damping element 10 has a first hole group 11 and a second hole group 12. The first hole group 11 includes a plurality of deformation holes arranged at intervals along the circumference of the damping element 10. The second hole group 12 includes a first connecting hole 121 and a second connecting hole 122. The connecting assembly 2 includes a first connecting member 21 that mates with the first connecting hole 121 and a second connecting member 22 that mates with the second connecting hole 122. Two adjacent damping elements 10 are made of the same material. The first connecting member 21 or the same second connecting member 22 are connected, such that the damping member 10 is connected to the damping member 10 adjacent to it on one side of the first direction D1 by the first connecting member 21, and the damping member 10 is connected to the damping member 10 adjacent to it on the other side of the first direction D1 by the second connecting member 22. In this way, when the damping structure rotates, the stress generated by the deformation of each damping member can work together with the adjacent damping members to generate torsional force, thereby generating resistance in the direction of rotation and playing a damping role. Since each damping member 10 has a deformation hole, the damping of each damping member 10 is reduced due to the deformation hole when it deforms. Therefore, the damping magnitude generated when the damping structure rotates can be controlled by adjusting the shape and size of the deformation hole and / or the number of damping members 10, the first connecting member 21 and the second connecting member 22 in the connecting assembly 2, according to the target stiffness requirements of the damping structure. Furthermore, the damping structure of this application does not require vulcanization injection molding of the metal, and can be directly assembled with the connecting component 2 after the damping component 10 is produced, reducing the manufacturing process, facilitating product production, and meeting the needs of mass production and industry applications of fully automated active lateral stabilizer bars.

[0052] A second aspect of the present invention provides an active lateral stabilizer bar, including the damping structure as described above, and thus possessing all the beneficial effects of the damping structure, which will not be repeated here.
