[0032] like Figures 1-3As shown in the accompanying drawings, the stabilizer bar 1 according to an embodiment of the present invention will be described below.

[0033] According to an embodiment of the present invention, the stabilizer bar 1 includes a torsion bar 100 and two swing arms 200.

[0034] The torsion bar 100 extends in a straight line, and two swing arms 200 are respectively provided at both ends of the torsion bar 100 and are set at an angle to the torsion bar 100. The swing arms 200 are provided with a first connecting part 210, and the torsion bar 100 is provided with a second connecting part 110. The first connecting part 210 and the second connecting part 110 are connected.

[0035] For example, the material of the swing arm 200 can be cast iron, and the material of the torsion bar 100 can be alloy structural steel.

[0036] The stabilizer bar 1, also known as the anti-roll bar, has a torsion bar 100 that can be connected to the vehicle frame. The two control arms 200 of the stabilizer bar 1 can be connected to the shock absorbers on the left and right sides of the vehicle, or directly to the axle. Specifically, when the vehicle body moves only vertically, the suspensions on both sides deform equally, and the stabilizer bar 1 has no effect. However, when the vehicle is turning or traveling on uneven surfaces, the stabilizer bar 1 prevents body roll. When the vehicle turns, the body is tilted outwards due to centrifugal force, causing the outer shock absorber to be compressed. The control arms 200 connected to the outer shock absorber transmit this pressure to the torsion bar 100. The torsion bar 100 generates a counterforce through its own torsion, which is applied to the inner shock absorber via the inner control arms 200. This allows the wheels on both sides to have better contact with the ground, reducing body roll and maintaining the vehicle's balance, thus providing lateral stability and ensuring stable turning. Furthermore, during vehicle operation, the stabilizer bar 1 can be used to reduce vehicle body sway, thereby improving vehicle handling stability and ride comfort, and providing a better driving experience, which is beneficial to improving user experience.

[0037] In addition, the two swing arms 200 are respectively located at both ends of the torsion bar 100 and are set at an angle to the torsion bar 100. This means that when the two swing arms 200 are connected to the torsion bar 100, the swing arms 200 and the torsion bar 100 are not collinear. This makes it easier for the torsion bar 100 and the swing arms 200 to be connected to the frame and axle or shock absorber respectively, and can optimize the force transmission path between the swing arms 200 and the torsion bar 100 to enhance the anti-roll capability of the stabilizer bar 1.

[0038] According to the present invention, the stabilizer bar 1 is constructed by making the torsion bar 100 extend in a straight line, for example, the torsion bar 100 extends in the left-right direction of the vehicle, and two swing arms 200 are respectively connected to the two ends of the torsion bar 100. This configuration eliminates the need to bend the torsion bar 100, which helps to reduce stress concentration on the torsion bar 100. Compared with the related technology that sets a bending structure on the torsion bar, the structural strength of the torsion bar 100 in the present invention embodiment can be higher, which helps to reduce fatigue damage of the torsion bar 100. This can extend the service life of the stabilizer bar 1, thereby enhancing the reliability and stability of the overall structure of the stabilizer bar 1.

[0039] Furthermore, by dividing the stabilizer bar 1 into a torsion bar 100 and two swing arms 200, and connecting the torsion bar 100 and the swing arms 200 to the second connecting part 110 through the first connecting part 210, the structure of the stabilizer bar 1 of this utility model is simpler than that formed by bending a single integral steel pipe. This not only facilitates processing but also avoids stress concentration at the connection between the torsion bar 100 and the swing arms 200, further improving the reliability of the stabilizer bar 1.

[0040] Thus, the stabilizer bar 1 according to the present utility model embodiment is assembled from a torsion bar 100 and a swing arm 200, and the torsion bar 100 extends in a straight line, which can effectively avoid stress concentration and has the advantages of simple structure, easy processing and high reliability.

[0041] In some specific embodiments of this utility model, such as Figure 2 As shown, one of the first connecting portion 210 and the second connecting portion 110 is a first insertion hole 211, and the other of the first connecting portion 210 and the second connecting portion 110 is a insertion post 111, which is inserted into the first insertion hole 211 with an interference fit.

[0042] For example, the first connecting portion 210 can be configured as a first insertion hole 211, and the second connecting portion 110 can be configured as a insertion post 111; or, the first connecting portion 210 can be configured as a insertion post 111, and the second connecting portion 110 can be configured as a first insertion hole 211.

[0043] In this way, the insertion post 111 can be cold-pressed into the first insertion hole 211 using an interference fit, making the connection between the rocker arm 200 and the torsion bar 100 more stable, avoiding relative swaying between the rocker arm 200 and the torsion bar 100, thereby improving the reliability of the stabilizer bar 1. Moreover, this arrangement can avoid stress concentration at the connection between the rocker arm 200 and the torsion bar 100, thus extending the service life of the stabilizer bar 1 and making the stabilizer bar 1 more reliable. Furthermore, it is understandable that by designing the stabilizer bar 1 as a combination structure of the rocker arm 200 and the torsion bar 100 and then cold-pressing them together with an interference fit, it is easier to process the torsion bar 100 and the rocker arm 200, which is beneficial to improving the processing efficiency of the stabilizer bar 1.

[0044] Furthermore, such as Figure 2 As shown, the first connecting part 210 is configured as a first insertion hole 211, which is located at the end of the swing arm 200, and the axial direction of the first insertion hole 211 is parallel to the length direction of the torsion bar 100.

[0045] With this configuration, the first insertion hole 211 and the torsion bar 100 can extend in the same direction, making the assembly between the first insertion hole 211 and the torsion bar 100 more convenient. Furthermore, the torsion bar 100 and the swing arm 200 are connected by insertion through the insertion post 111 and the first insertion hole 211, which can better avoid stress concentration at the connection between the torsion bar 100 and the swing arm 200, thereby improving the stability of the connection between the swing arm 200 and the torsion bar 100 and making the stability bar 1 more reliable.

[0046] Furthermore, the force generated when the vehicle is turning can be transmitted to the torsion bar 100 more efficiently through the swing arm 200. This improves the force transmission efficiency and allows the stabilizer bar 1 to respond more quickly according to the vehicle's driving conditions, thereby reducing body sway and improving the vehicle's ride comfort.

[0047] In some specific embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the swing arm 200 also includes a main body 220, a first connecting part 210 connected to one end of the main body 220, and the main body 220 extends in a direction perpendicular to the torsion bar 100.

[0048] By extending the main body 220 in a direction perpendicular to the torsion bar 100, the swing arm 200 can be vertically connected to the torsion bar 100, which helps to optimize the force transmission path on the torsion bar 100 and the swing arm 200. When the vehicle is turning, the torsion bar 100 can transmit the torsional force to the axle or shock absorber through the swing arm 200, thereby effectively resisting body roll and ensuring the vehicle's handling and ride comfort.

[0049] In addition, it is understandable that in practice, in order to take into account the movement trajectory of other components and avoid motion interference between the stabilizer bar 1 and other components, the swing arm 200 and the torsion bar 100 can also be set to be non-perpendicular.

[0050] Furthermore, such as Figure 3 As shown, the first connecting portion 210 is configured as a first insertion hole 211, and along the axial direction of the first insertion hole 211, the length of the first connecting portion 210 is greater than the thickness of the main body portion 220.

[0051] In this way, the length of the first insertion hole 211 can be relatively long along the axial direction of the torsion bar 100, thereby increasing the contact area between the first insertion hole 211 and the insertion post 111, so that the connection between the first insertion hole 211 and the insertion post 111 is more stable, thereby improving the connection strength between the swing arm 200 and the torsion bar 100, and improving the reliability and stability of the overall structure of the stabilizer bar 1.

[0052] In some specific embodiments of this utility model, such as Figure 3 As shown, the cross-sectional shape of the main body 220 is I-shaped. In this way, while improving the structural strength of the main body 220, the weight of the main body 220 can be significantly reduced, and the weight of the swing arm 200 can be lighter, thereby achieving the weight reduction of the stabilizer bar 1 and facilitating the assembly and use of the stabilizer bar 1.

[0053] Furthermore, such as Figure 3 As shown, the main body 220 includes a first reinforcing section 221, a connecting section 222, and a second reinforcing section 223.

[0054] The first reinforcing section 221, the connecting section 222, and the second reinforcing section 223 extend along the length direction of the main body 220, and the first reinforcing section 221 and the second reinforcing section 223 are located on opposite sides of the connecting section 222.

[0055] The width of the first reinforcing section 221 and the width of the second reinforcing section 223 are greater than the width of the connecting section 222, and the first reinforcing section 221, the connecting section 222 and the second reinforcing section 223 are arranged radially along the first connecting portion 210.

[0056] In other words, both sides of the first reinforcing section 221 and the second reinforcing section 223 can protrude from the connecting section 222, thus the first reinforcing section 221, the connecting section 222, and the second reinforcing section 223 can be constructed as an I-beam structure. Furthermore, by setting the width of the first reinforcing section 221 and the second reinforcing section 223 to be larger, the structural strength of the main body 220 can be improved, thereby increasing the bending stiffness and strength of the overall structure of the swing arm 200. This can improve the load-bearing capacity of the swing arm 100 and improve the force transmission efficiency between the swing arm 200 and the torsion bar 100, so that the stabilizer bar 1 can adjust the vehicle body state more quickly to ensure driving stability.

[0057] Furthermore, by arranging the first reinforcing section 221, the connecting section 222, and the second reinforcing section 223 radially along the first insertion hole 211, that is, arranging the first reinforcing section 221, the connecting section 222, and the second reinforcing section 223 in a direction perpendicular to the axial direction of the torsion bar 100, this arrangement not only improves the connection strength between the main body 220 and the first connecting part 210, but also allows the swing arm 200 to support the torsion bar 100 more stably, so that the torsion bar 100 can quickly recover after torsional deformation, thereby improving the reliability of the stabilizer bar 1.

[0058] In some specific embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the swing arm 200 also includes a third connecting part 230, which is connected to the end of the main body 220 away from the first connecting part 210. The third connecting part 230 is configured as a second insertion hole 231, and a ball joint 300 is provided in the second insertion hole 231. The ball joint 300 and the second insertion hole 231 are interference-fitted.

[0059] For example, the ball joint 300 can be a combination of metal and rubber.

[0060] The stabilizer bar 1 can be connected to the axle or shock absorber via a ball joint 300. This allows the swing arm 200 to be flexibly connected to the axle or shock absorber. Understandably, the ball joint 300 has a large degree of freedom, which allows the swing arm 200 to move together with the axle or shock absorber. This ensures a smoother and more stable force transmission between the axle or shock absorber and the stabilizer bar 1, thereby ensuring driving stability. This is beneficial for enhancing the driver's control and the passenger's ride comfort. Furthermore, the ball joint 300 has a relatively simple and compact structure, making it easy to install and disassemble, reducing maintenance difficulty and time costs.

[0061] In some specific embodiments of this utility model, such as Figure 2 and Figure 3 As shown, torsion bar 100 is a hollow component, and swing arm 200 is a solid component.

[0062] For example, the torsion bar 100 can be a hollow steel pipe, and the swing arm 200 can be a cast iron I-beam structure.

[0063] By designing the torsion bar 100 as a hollow steel tube, the ratio of the inner and outer diameters and the wall thickness of the hollow steel tube can be adjusted to adjust the structural strength of the torsion bar 100, so that the stabilizer bar 1 can be matched with different vehicle models, thereby enhancing the versatility of the stabilizer bar 1.

[0064] In addition, by constructing the swing arm 200 as a solid part, the injection molding difficulty of the swing arm 200 can be reduced, making it easier to process. Furthermore, the structural strength of the swing arm 200 as a solid part is more uniform throughout, which further improves the structural stability of the swing arm 200 and makes the stability bar 1 more reliable.

[0066] The vehicle according to the present invention utilizes the stabilizer bar 1 according to the above embodiment of the present invention. The stabilizer bar 1 is assembled from a torsion bar 100 and a swing arm 200, and the torsion bar 100 extends in a straight line, which can effectively avoid stress concentration and has the advantages of simple structure, easy processing and high reliability.
