Description

Technical Field

[0001] The present application relates to the technical field of stabilizer bars, and in particular to a fixing member and a stabilizer bar assembly. Background Art

[0002] The stabilizer bar, also known as the anti-roll bar or balance bar, is an auxiliary elastic element on the vehicle, used to maintain the balance of the vehicle body and reduce the vibration and swaying of the vehicle body. The stabilizer bar is fixed to the frame through a clamp and a bushing, but the existing clamp has poor connection reliability with the stabilizer bar and the stabilizer bar is prone to shaking relative to the clamp. The shaking of the stabilizer bar relative to the clamp causes the bushing and the clamp to rub against each other continuously, which will produce abnormal noise and affect the user experience. On the other hand, it will also shorten the service life of the bushing and increase the maintenance cost. Utility Model Content

[0003] The present application provides a fixing member and a stabilizer bar assembly, which are used to solve the problems that the connection reliability between the existing fixing member and the stabilizer bar is poor and the stabilizer bar is easy to shake relative to the fixing member.

[0004] A fixing member provided in an embodiment of the present application is used to fix a stabilizer bar to a vehicle frame, the fixing member comprising a main body and side edges, the main body having a clamping space for clamping the stabilizer bar, the side edges being arranged on both sides of the main body along the axial direction of the stabilizer bar, the side edges protruding relative to the main body; a projection area of ​​at least a portion of the side edges in the axial direction of the stabilizer bar gradually decreases from the center of the main body to both sides of the main body.

[0005] In a possible design, the body includes an arc portion and an extension portion, the arc portion encloses at least a portion of the clamping space, and the extension portion is arranged on both sides of the arc portion along the radial direction for connection with the frame.

[0006] In a possible design, a first distance d1 is provided between two sides of the side edge along the extension direction of the extension portion, and the first distance d1 increases in a direction approaching the extension portion.

[0007] In a possible design, along the axial direction of the arc portion, there is a second distance d2 between the two side edges on both sides of the body, and along the direction approaching the extension portion, the second distance d2 increases.

[0008] In a possible design, a recessed portion is provided on the arc portion, and the recessed portion is recessed toward the clamping space.

[0009] In a possible design, the arc portion is U-shaped.

[0010] In a possible design, the side includes a first section and a second section, the first section is farther away from the extension portion than the second section, an edge of the first section is a straight line, and an edge of the second section is a spiral curve.

[0011] In a possible design, an angle α is formed between a projection of the first section along the extension direction of the extension portion and a horizontal direction, and the angle α satisfies: 45°≤α≤90°.

[0012] In a possible design, the thickness t of the body satisfies: 2.5 mm ≤ t ≤ 4 mm.

[0013] A stabilizer bar assembly provided in this embodiment includes: a stabilizer bar and a fixing member, wherein the fixing member clamps the stabilizer bar, and the fixing member is the fixing member described above.

[0014] In the present application, at least part of the stabilizer bar is accommodated in the clamping space, and the side edge abuts against the bushing, so that the bushing limits the movement of the stabilizer bar in the axial direction, improves the connection reliability between the fixing part and the stabilizer bar, and further reduces the abnormal noise generated by the movement of the stabilizer bar relative to the fixing part. The side edge is arranged on both sides of the body along the axial direction of the stabilizer bar, and the side edges on both sides can limit the movement of the stabilizer bar in the axial direction, further improving the connection reliability between the fixing part and the stabilizer bar. In addition, the side edge can also increase the strength and rigidity of the fixing part, improve the fatigue resistance of the fixing part, and extend the service life of the fixing part. The projection area of ​​at least part of the side edge in the axial direction of the stabilizer bar gradually decreases from the center of the body to the two sides of the body, which, on the one hand, makes the volume of the side edge smaller, which is conducive to the lightweight of the fixing part and the stabilizer bar assembly, and on the other hand, facilitates the demoulding of the fixing part when producing the fixing part, and improves the production yield and production efficiency of the fixing part.

[0034] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0035] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0037] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0038] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0039] like Figure 1 As shown, the stabilizer bar assembly includes a stabilizer bar 4, a bushing 3 and a fixing part. The bushing 3 is vulcanized onto the stabilizer bar 4 to form an integrated structure with the stabilizer bar 4. The fixing part is clamped on the outside of the bushing 3 and connected to the frame, thereby installing the stabilizer bar 4 on the frame.

[0040] The present application provides a fixing member for fixing the stabilizer bar 4 to the vehicle frame. Figure 2 As shown, the fixing member includes a main body 1 and a side 2, the main body 1 has a clamping space 13 for clamping the stabilizing bar 4, the side 2 is arranged on both sides of the main body 1 along the axial direction of the stabilizing bar 4, and the side 2 protrudes relative to the main body 1; the projection area of ​​at least part of the side 2 in the axial direction of the stabilizing bar 4 gradually decreases from the center of the main body 1 to both sides of the main body 1.

[0041] In this embodiment, if Figure 1 and Figure 2 As shown, at least part of the stabilizer bar 4 is accommodated in the clamping space 13, and the side edge 2 abuts against the bushing 3, so that the movement of the stabilizer bar 4 in the axial direction is limited by the bushing 3, thereby improving the connection reliability between the fixing part and the stabilizer bar 4, and further reducing the abnormal noise generated by the movement of the stabilizer bar 4 relative to the fixing part. The side edges 2 are arranged on both sides of the body 1 along the axial direction of the stabilizer bar 4, and the side edges 2 on both sides can limit the movement of the stabilizer bar 4 in the axial direction, further improving the connection reliability between the fixing part and the stabilizer bar 4. In addition, the side edges 2 can also increase the strength and rigidity of the fixing part, improve the fatigue resistance of the fixing part, and extend the service life of the fixing part.

[0042] The projected area of ​​at least part of the side edge 2 in the axial direction of the stabilizer bar 4 gradually decreases from the center of the main body 1 to both sides of the main body 1. On the one hand, this makes the volume of the side edge 2 smaller, which is beneficial to the lightweight of the fixing part and the stabilizer bar assembly. On the other hand, it is convenient to demould the fixing part during production, thereby improving the production yield and production efficiency of the fixing part.

[0043] In a specific embodiment, Figure 2 As shown, the body 1 includes an arc portion 11 and an extension portion 12. The arc portion 11 encloses at least a portion of a clamping space 13. The extension portion 12 is disposed on both sides of the arc portion 11 along the radial direction for connection with the vehicle frame.

[0044] In this embodiment, if Figure 2 As shown, the inner side of the arc portion 11 abuts against the bushing 3, so that the contact area between the fixing member and the bushing 3 is larger, and further makes it difficult for the bushing 3 and the stabilizer bar 4 to shake in the axial direction or radial direction relative to the fixing member, preventing the fixing member from scratching the bushing 3 or generating abnormal noise, thereby improving the installation effect of the stabilizer bar 4. The extension portion 12 is in a flat plate shape and can fit tightly with the frame, so as to achieve a reliable connection between the fixing member and the frame.

[0045] Specifically, Figure 2 As shown, the arc portion 11 is U-shaped, so it is easy to form the arc portion 11 by stamping, which has the advantages of simple process, high material utilization, easy production and low production cost. In addition, the U-shaped arc portion also makes the stabilizer bar assembly easy to assemble and has high assembly efficiency.

[0046] In a specific embodiment, Figure 3 As shown, the extension portion 12 is provided with a connecting hole 121 , and the connecting holes 121 on the two extension portions 12 are one circular hole and the other waist-shaped hole.

[0047] In this embodiment, if Figure 3 As shown, the fixing member can be connected to the frame by passing the connecting member through the connecting hole 121, thereby realizing a reliable connection between the fixing member and the frame. Among them, the circular connecting hole 121 can play a positioning role, thereby improving the installation accuracy of the fixing member on the frame, and the waist-shaped connecting hole 121 can reduce the installation difficulty of the fixing member and prevent the fixing member from being unable to be installed due to dimensional errors. In addition, the connecting member can be a bolt, a screw, etc.

[0048] In a specific embodiment, Figure 2 and Figure 3 As shown, a recessed portion 111 is provided on the arc portion 11 , and the recessed portion 111 is recessed toward the clamping space 13 .

[0049] In this embodiment, if Figure 2 and Figure 3 As shown, the recessed portion 111 can provide an escape space for the installation of the connecting piece, preventing the fixing piece from being unable to be installed due to the arc portion 11 hindering the rotation of tools such as a wrench. At the same time, the recessed portion 111 can also improve the rigidity of the body 1, making it difficult for the fixing piece to be deformed or damaged when impacted, and cooperate with the bushing 3 to limit the shaking of the stabilizing rod 4 relative to the fixing piece, preventing abnormal noise.

[0050] Specifically, the recessed portions 111 are symmetrically arranged on both sides of the arc portion 11 , thereby providing avoidance space for fixing the two extension portions 12 .

[0051] More specifically, the recessed portion 111 is located at the end of the arc portion 11 close to the extending portion 12 , so that the recessed portion 111 can provide support for the bushing 3 in the radial direction and limit the movement of the bushing 3 relative to the fixing member in the radial direction.

[0052] In a specific embodiment, Figure 4 and Figure 5 As shown, there is a first distance d1 between the two sides of the side edge 2 along the extension direction of the extension portion 12, and the first distance d1 increases in the direction close to the extension portion 12. Along the axial direction of the arc portion 11, there is a second distance d2 between the two side edges 2 on both sides of the body 1, and the second distance d2 increases in the direction close to the extension portion 12.

[0053] In this embodiment, if Figure 4 As shown, along the direction close to the extension portion 12, the first distance d1 increases so that the side edge 2 can guide the installation of the bushing 3 and the stabilizer bar 4, thereby facilitating the installation of the bushing 3 and the stabilizer bar 4. Figure 5 As shown, the second distance d2 increases in the direction approaching the extension portion 12 , and the side edge 2 can guide the installation of the bushing 3 and the stabilizer bar 4 , thereby facilitating the installation of the bushing 3 and the stabilizer bar 4 .

[0054] In a specific embodiment, Figure 4 and Figure 5 As shown, the side edge 2 includes a first section 21 and a second section 22 , the first section 21 is farther away from the extension portion 12 than the second section 22 , the edge of the first section 21 is a straight line, and the edge of the second section 22 is a spiral curve.

[0055] In this embodiment, if Figure 4 and Figure 5 As shown, the first section 21 can abut against the bushing 3, thereby providing a better limiting effect on the bushing 3; the edge of the second section 22 is a spiral curve, which reduces the contact area between the side 2 and the bushing 3, so that the shearing effect of the side 2 on the bushing 3 is smaller.

[0056] Furthermore, if Figure 5 As shown, the projection of the first section 21 along the extension direction of the extension portion 12 has an angle α with the horizontal direction, and the angle α satisfies: 45°≤α≤90°. For example, the angle α can be 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, 90°, etc.

[0057] like Figure 5As shown, the angle α should not be too large or too small. If the angle α is too large (for example, greater than 90°), the second distance d2 gradually decreases along the direction close to the extension portion 12, which increases the difficulty of installing the bushing 3 and the stabilizer bar 4, is not conducive to the installation of the bushing 3 and the stabilizer bar 4, and greatly increases the difficulty of producing the fixing part by stamping; if the angle α is too small (for example, less than 45°), the second distance d2 increases too much along the direction close to the extension portion 12, which is not conducive to the limiting effect of the side 2 on the bushing 3. Therefore, the angle α should be selected within an appropriate range.

[0058] In a specific implementation, the thickness t of the body 1 satisfies: 2.5 mm ≤ t ≤ 4 mm. For example, the thickness t of the body 1 can be 2.5 mm, 2.8 mm, 3 mm, 3.2 mm, 3.5 mm, 3.8 mm, 4 mm, etc.

[0059] In this embodiment, the thickness t of the body 1 should not be too thick or too thin. If the thickness t of the body 1 is too thick (for example, t>4mm), the weight of the fixing part is too heavy, which is not conducive to achieving lightweight of the fixing part and also makes the cost of the fixing part high. If the thickness t of the body 1 is too thin (for example, t<2.5mm), the strength and rigidity of the body 1 are poor, and the fatigue durability of the fixing part is poor and easy to be damaged. Therefore, the thickness t of the body 1 should be selected within an appropriate range. Preferably, the thickness t of the body 1 is 3.5mm.

[0060] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
