[0033] Reference below Figure 1-Figure 5 A stabilizer bar 100 for a vehicle according to an embodiment of the present invention will be described.

[0034] Reference Figure 1 、 Figure 2 and Figure 5 According to an embodiment of the present invention, a stabilizer bar 100 for a vehicle includes a first arm assembly 10 , a second arm assembly 20 , a first magnetic member 30 , and a second magnetic member 40 .

[0035] The first arm assembly 10 is used to connect to the first wheel of the vehicle. The second arm assembly 20 is used to connect to the second wheel of the vehicle, and the second wheel and the first wheel are arranged on the left and right sides of the vehicle. The first magnetic member 30 is arranged on the first arm assembly 10, and the second magnetic member 40 is movably arranged on the second arm assembly 20. At least one of the first magnetic member 30 and the second magnetic member 40 is configured as a controllable electromagnetic member. Among them, the second magnetic member 40 can be moved to the working position, the second magnetic member 40 is connected to the first magnetic member 30, so that the second arm assembly 20 is stationary relative to the first arm assembly 10, and the second magnetic member 40 can be moved to the disconnection position, the second magnetic member 40 is disconnected from the first magnetic member 30, so that the second arm assembly 20 is suitable for rotating relative to the first arm assembly 10.

[0036] The second magnetic member 40 has a working position and an off position, referring to Figure 5 , the second magnetic member 40 is located in the working position, and the second magnetic member 40 is connected to the first magnetic member 30, so that the second arm assembly 20 is stationary relative to the first arm assembly 10, referring to Figure 2 , the second magnetic member 40 is located in the disconnected position, and the second magnetic member 40 is disconnected from the first magnetic member 30 , so that the second arm assembly 20 is suitable for rotating relative to the first arm assembly 10 .

[0037] The vehicle has a first wheel and a second wheel facing each other. Specifically, the first wheel and the second wheel are opposite each other on the left and right sides. A magnetic force is generated between the first magnetic member 30 and the second magnetic member 40. The first magnetic member 30 is mounted on the first arm assembly 10, and the second magnetic member 40 is mounted on the second arm assembly 20. Under the action of the force, the second magnetic member 40 switches between the working position and the disconnected position, thereby switching the mode of the stabilizer bar 100 to adapt to different operating conditions.

[0038] At least one of the first magnetic member 30 and the second magnetic member 40 is configured as a controllable electromagnetic member, so as to control the second magnetic member 40 to approach or move away from the first magnetic member 30 and switch between different modes.

[0039] Stabilizer bar 100, as an elastic component, plays an auxiliary role in the vehicle's suspension system, suppressing excessive lateral roll during cornering and preventing the vehicle from rolling over. Prior art stabilizer bars have complex structures and can only be disconnected on level surfaces, placing high demands on the environment.

[0040] In the embodiment of the present invention, through the cooperation of the first magnetic part 30 and the second magnetic part 40, the first magnetic part 30 is connected to the second magnetic part 40, so that the second arm assembly 20 is stationary relative to the first arm assembly 10. The stabilizer bar 100 in the present invention plays the role of a conventional stabilizer bar, and the first magnetic part 30 is disconnected from the second magnetic part 40, so that the second arm assembly 20 is suitable for rotating relative to the first arm assembly 10. The first arm assembly 10 and the second arm assembly 20 have a larger swing angle, which can adjust the tilt angle of the vehicle.

[0041] Specifically, the second magnetic member 40 moves along the axial direction of the second arm assembly 20 , and the second magnetic member 40 rotates coaxially with the second arm assembly 20 .

[0042] Specifically, the second magnetic member 40 moves away from or close to the first magnetic member 30, thereby switching between the disconnected position and the working position. The first magnetic member 30 and the second magnetic member 40 can be attracted or repelled by magnetic force; magnetic force can also be used alone for attraction, and other forces can be used for repulsion. For example, the second magnetic member 40 is connected to a spring, and the spring pulls the second magnetic member 40 away from the first magnetic member 30. The magnetic force between the first magnetic member 30 and the second magnetic member 40 makes the second magnetic member 40 close to the first magnetic member 30. The magnetic force can also be used alone for repulsion, and other forces can be used for attraction. For example, the second magnetic member 40 is connected to a spring, and the spring pulls the second magnetic member 40 close to the first magnetic member 30. The magnetic force between the first magnetic member 30 and the second magnetic member 40 makes the second magnetic member 40 away from the first magnetic member 30.

[0043] For example, both the first magnetic component 30 and the second magnetic component 40 are electromagnetic components. The direction of the magnetic field is controlled by controlling the direction of the current, and then the second magnetic component 40 is controlled to move away from or close to the first magnetic component 30. The specific principle is existing technology and will not be repeated here.

[0044] Alternatively, the first magnetic member 30 is an electromagnetic member, the second magnetic member 40 is a permanent magnet, the first magnetic member 30 is energized, and the direction of the current is controlled to control the second magnetic member 40 to approach or move away from the first magnetic member 30. Alternatively, the first magnetic member 30 is an electromagnetic member, the second magnetic member 40 is a permanent magnet, the first magnetic member 30 is energized, and the direction of the current is controlled to control the second magnetic member 40 to approach the first magnetic member 30, and accordingly, other forces are used to control the second magnetic member 40 to move away from the first magnetic member 30. Alternatively, the first magnetic member 30 is an electromagnetic member, the second magnetic member 40 is a permanent magnet, the first magnetic member 30 is energized, and the direction of the current is controlled to control the second magnetic member 40 to move away from the first magnetic member 30, and accordingly, other forces are used to control the second magnetic member 40 to move toward the first magnetic member 30.

[0045] Alternatively, the first magnetic member 30 is a permanent magnet, the second magnetic member 40 is an electromagnetic member, the second magnetic member 40 is energized, and the direction of the current is controlled to control the second magnetic member 40 to approach or move away from the first magnetic member 30. Alternatively, the first magnetic member 30 is a permanent magnet, the second magnetic member 40 is an electromagnetic member, the second magnetic member 40 is energized, and the direction of the current is controlled to control the second magnetic member 40 to approach the first magnetic member 30, and accordingly, other forces are used to control the second magnetic member 40 to move away from the first magnetic member 30. Alternatively, the first magnetic member 30 is a permanent magnet, the second magnetic member 40 is an electromagnetic member, the second magnetic member 40 is energized, and the direction of the current is controlled to control the second magnetic member 40 to move away from the first magnetic member 30, and accordingly, other forces are used to control the second magnetic member 40 to move toward the first magnetic member 30.

[0046] According to the stabilizer bar 100 of the vehicle in the embodiment of the present invention, through the cooperation of the first magnetic part 30 and the second magnetic part 40, the electromagnetic effect of like poles repelling each other and opposite poles attracting each other is utilized to achieve switching of multiple modes. The overall structure is simpler. Compared with the electronically controlled semi-active stabilizer bar solution in the related art, the stabilizer bar 100 in the embodiment of the present invention can be operated on any road surface and is not affected by the environment. At the same time, the structure is simplified. Compared with the related art, there is no noise problem when the gears rotate, thereby reducing vehicle noise.

[0047] In some embodiments, the first magnetic component 30 is configured as a first electromagnetic component, and the second magnetic component 40 is configured as a second electromagnetic component. The first electromagnetic component and the second electromagnetic component are respectively connected to a control component.

[0048] The first magnetic component 30 is constructed as a first electromagnetic component, and the second magnetic component 40 is constructed as a second electromagnetic component. The first electromagnetic component and the second electromagnetic component are respectively connected to a control component, which controls the direction of the current in the first electromagnetic component and the second electromagnetic component, thereby controlling the direction of the magnetic field.

[0049] In the above solution, by constructing the first magnetic component 30 as a first electromagnetic component and the second magnetic component 40 as a second electromagnetic component, the directions of the magnetic fields generated by the first electromagnetic component and the second electromagnetic component can be adjusted, making the control of the stabilizer bar 100 more convenient and improving operability.

[0050] Specifically, there may be one control component, which is respectively connected to the first electromagnetic component and the second electromagnetic component; or there may be two control components, each of which is independently electrically connected to a corresponding electromagnetic component.

[0051] Specifically, the first electromagnetic component is a first magnetic yoke, and the second electromagnetic component is a second magnetic yoke, which generate a magnetic field when energized.

[0052] Reference Figure 2 and Figure 3In some embodiments, the surface of the first magnetic component 30 facing the second magnetic component 40 is configured as a first friction surface 31, and the surface of the second magnetic component 40 facing the first magnetic component 30 is configured as a second friction surface 41, and the first friction surface 31 and the second friction surface 41 are frictionally matched.

[0053] Among them, the surface of the first magnetic part 30 facing the second magnetic part 40 is constructed as a first friction surface 31, and the surface of the second magnetic part 40 facing the first magnetic part 30 is constructed as a second friction surface 41. The first magnetic part 30 is connected to the second magnetic part 40, and the first friction surface 31 is attached to the second friction surface 41. There is friction between the two, so that the first magnetic part 30 and the second magnetic part 40 are relatively stationary.

[0054] In the above scheme, the surface of the first magnetic component 30 facing the second magnetic component 40 is constructed as the first friction surface 31, and the surface of the second magnetic component 40 facing the first magnetic component 30 is constructed as the second friction surface 41. The friction force between the first friction surface 31 and the second friction surface 41 is utilized to keep the first magnetic component 30 and the second magnetic component 40 relatively stationary. The overall structure is simple and switching is convenient.

[0055] In other embodiments, one of the first magnetic member 30 and the second magnetic member 40 is provided with a protrusion, and the other is provided with a groove, and the protrusion cooperates with the groove so that the two remain relatively stationary.

[0056] In some embodiments, the first friction surface 31 is a first plane, the second friction surface 41 is a second plane, and the first plane is in contact with the second plane.

[0057] The entire surface of the first magnetic component 30 facing the second magnetic component 40 is a plane without protrusions, and the entire surface of the second magnetic component 40 facing the first magnetic component 30 is a plane without protrusions. The two planes fit together and are in full contact.

[0058] In the above scheme, by constructing the first friction surface 31 as a first plane and the second friction surface 41 as a second plane, the first plane and the second plane are fully fitted together, thereby increasing the friction force and facilitating the connection between the first magnetic part 30 and the second magnetic part 40. It can be understood that the surface-to-surface matching method can be quickly connected and disconnected in any working conditions.

[0059] Reference Figure 2 、 Figure 3 In some embodiments, the second arm assembly 20 is provided with a guiding portion 21 , and the second magnetic member 40 is provided with a matching portion 42 , and the matching portion 42 matches the guiding portion 21 to guide the movement of the second magnetic member 40 .

[0060] The matching portion 42 matches the guiding portion 21 , and the guiding portion 21 guides the movement of the matching portion 42 , so that the second magnetic member 40 moves along a predetermined trajectory.

[0061] In the above solution, through the cooperation between the guiding portion 21 and the matching portion 42 , the guiding portion 21 guides the matching portion 42 , thereby making the second magnetic member 40 move more stably, thereby improving the working stability of the stabilizing bar 100 .

[0062] Specifically, the mating portion 42 is configured as an extension post, and the guide portion 21 is configured as a guide hole. The extension post is inserted into the guide hole, and the guide hole guides the movement of the extension post. Alternatively, the mating portion 42 is configured as a mating hole, and the guide portion 21 is configured as a guide post. The guide post is inserted into the mating hole, and the guide post guides the movement of the second magnetic member 40. Of course, the mating portion 42 and the guide portion 21 can also have other specific structures, which will not be repeated here.

[0063] In some embodiments, the guide portion 21 is configured as a guide hole, and the matching portion 42 is configured as an extension column, which is suitable for being inserted into the guide hole.

[0064] The extension column is inserted into the guide hole, and the inner wall of the guide hole limits the movement of the extension column, so that the movement of the extension column follows a predetermined trajectory, and the second magnetic member 40 moves along the predetermined trajectory.

[0065] In the above solution, the movement of the second magnetic member 40 is guided by the cooperation between the guide hole and the extension column, so that the movement of the second magnetic member 40 is more stable, the overall structure is simpler, and molding and manufacturing are convenient.

[0066] Reference Figure 2 、 Figure 3 In some embodiments, the second arm assembly 20 includes: a second cross arm 22 and a chuck 23 .

[0067] The second magnetic member 40 is sleeved on the second cross arm 22. The chuck 23 is fixedly connected to the second cross arm 22 via a second spline 222, and the guide hole is provided on the chuck 23.

[0068] Among them, the chuck 23 is sleeved on the second cross arm 22, and a second spline 222 is provided between the chuck 23 and the second cross arm 22. The chuck 23 is fixed on the second cross arm 22, and the second magnetic part 40 is also sleeved on the second cross arm 22. The second magnetic part 40 corresponds to the chuck 23, and the extension part on the second magnetic part 40 is inserted into the guide hole on the chuck 23.

[0069] In the above scheme, through the cooperation between the second cross arm 22 and the chuck 23, the second magnetic part 40 does not need to be precisely matched with the second cross arm 22, and the chuck 23 is fixed to the second cross arm 22 through the second spline 222. The overall structure is easy to assemble, reduces precision requirements, and reduces costs.

[0070] Specifically, the second magnetic member 40 has a through hole, the second cross arm 22 is a columnar member, and the through hole is sleeved on the second cross arm 22 .

[0071] Reference Figure 2 、 Figure 3 and Figure 4 In some embodiments, the first arm assembly 10 includes: a first swing arm 11 and a first cross arm 12 .

[0072] The first swing arm 11 is used to connect to the first wheel. The first cross arm 12 is connected to the first swing arm 11, and the first magnetic member 30 is fixedly connected to the first cross arm 12 via a first spline 122. The second arm assembly 20 also includes a second swing arm 24, one end of which is connected to the second wheel and the other end is connected to the second cross arm 22. The stabilizer bar 100 also includes a housing 50, which is provided with a receiving space 51. The first cross arm 12 is partially provided in the receiving space 51. The first magnetic member 30 and the second magnetic member 40 are provided in the receiving space 51. The second cross arm 22 is partially provided in the receiving space 51.

[0073] Among them, the first swing arm 11 is connected to the first cross arm 12, the second swing arm 24 is connected to the second cross arm 22, the first swing arm 11 is connected to the first wheel, the second swing arm 24 is connected to the second wheel, and the first cross arm 12 and the second cross arm 22 are arranged in parallel and coaxially.

[0074] In the above scheme, a first spline 122 is provided between the first magnetic part 30 and the first cross arm 12, and a second spline 222 is provided between the chuck 23 and the second cross arm 22, so as to fix the first magnetic part 30 and the chuck 23, improve stability, and make the overall structure more stable. In addition, the first cross arm 12 and the first swing arm 11 are arranged separately, and the second cross arm 22 and the second swing arm 24 are arranged separately, which facilitates molding and reduces costs.

[0075] Specifically, the guide hole is provided on the chuck 23 , and the chuck 23 is mounted on the second cross arm 22 via the second spline 222 , which is more convenient for manufacturing and molding.

[0076] Specifically, the first swing arm 11 and the first transverse arm 12 are constructed as hollow structures, which effectively reduce the unsprung mass of the vehicle, improve the handling performance of the entire vehicle, and at the same time reduce fuel consumption.

[0077] Specifically, the first swing arm 11 is fixedly connected to the first transverse arm 12 via a third spline, and the second swing arm 24 is fixedly connected to the second transverse arm 22 via a fourth spline.

[0078] Furthermore, the housing 50 has an accommodating space 51 therein for accommodating the first magnetic component 30 and the second magnetic component 40 . The first cross arm 12 partially extends into the accommodating space 51 , and the second cross arm 22 partially extends into the accommodating space 51 .

[0079] In the above solution, the housing 50 is provided to accommodate the first magnetic component 30 and the second magnetic component 40 , so that the components are isolated from the outside world to avoid interference, thereby improving reliability.

[0080] Reference Figure 2 、 Figure 3 and Figure 4 In some embodiments, the housing 50 includes a first shell 52 and a second shell 53 .

[0081] The first shell 52 has a first avoidance hole 521 through which the first cross arm 12 is inserted. The second shell 53 has a second avoidance hole 531 through which the second cross arm 22 is inserted. The second shell 53 is connected to the first shell 52.

[0082] Among them, the first shell 52 and the second shell 53 are matched, for example, by threaded fit or interference fit, to connect the first shell 52 and the second shell 53. The split structure is convenient for molding, and is provided with a first avoidance hole 521 and a second avoidance hole 531. The first shell 52 is sleeved on the first cross arm 12, and the second shell 53 is sleeved on the second cross arm 22, which is more reliable as a whole.

[0083] Specifically, a bushing is provided between the first shell 52 and the first cross arm 12 , and the bushing is vulcanized integrally with the first cross arm 12 and the second cross arm 22 , thereby improving product reliability and effectively avoiding abnormal noise problems caused by the split bushing.

[0084] Reference Figure 3 In some embodiments, a first sealing ring 121 is provided between the first cross arm 12 and the first shell 52, and a second sealing ring 221 is provided between the second cross arm 22 and the second shell 53, thereby improving the sealing performance.

[0085] Specifically, the stabilizer bar 100 is an electromagnetic friction type semi-active stabilizer bar. When the electromagnetic friction type semi-active stabilizer bar is in the disconnection mode, Figure 3, the electromagnetic coils of the first electromagnetic component and the second electromagnetic component inside the accommodating space 51 are energized, and the first electromagnetic component and the second electromagnetic component are disconnected due to the principle of like poles repelling each other; the first electromagnetic component is fixed to the first cross arm 12 through the first spline 122, and the second electromagnetic component slides through the guide hole of the chuck 23 to generate movement, and the chuck 23 is fixedly connected to the second cross arm 22 through the second spline 222. When the vehicle is driving on an uneven road, the connecting rod of the automobile stabilizer bar 100 drives the second swing arm 24 to swing, and the second swing arm 24 is fixedly connected to the second transverse arm 22, so the second transverse arm 22 and the second swing arm 24 rotate together, and the second transverse arm 22 drives the chuck 23 to rotate through the second spline 222, and the chuck 23 drives the second electromagnetic component to rotate; the relatively first swing arm 11 drives the first transverse arm 12 to rotate through the first spline 122, and the first transverse arm 12 drives the first electromagnetic component to rotate through the first spline 122; when the electromagnetic friction semi-active stabilizer bar is disconnected on such an uneven road, the first swing arm 11 and the second swing arm 24 have a larger swing angle, which can adjust the roll angle of the vehicle.

[0086] Specifically, when the electromagnetic friction semi-active stabilizer bar is in the connection mode, the electromagnetic coils of the first electromagnetic component and the second electromagnetic component in the accommodating space 51 are energized. Figure 5 Due to the principle of opposite poles attracting each other, the first and second electromagnetic components are connected, and the friction at the connection is extremely high and cannot rotate. The first electromagnetic component is fixed to the first cross arm 12 via a first spline 122. The second electromagnetic component and the guide hole of the chuck 23 cannot slide. The chuck 23 is fixedly connected to the second cross arm 22 via a second spline 222. The first swing arm 11 and the second swing arm 24 cannot rotate relative to each other, functioning as a conventional stabilizer bar 100.

[0087] A vehicle according to an embodiment of the present invention includes the stabilizer bar 100 described above.

[0088] According to the vehicle of the embodiment of the present invention, the above-mentioned stabilizer bar 100 is installed. Through the cooperation of the first magnetic part 30 and the second magnetic part 40, the electromagnetic effect is utilized to realize switching of multiple modes due to like poles repelling each other and opposite poles attracting each other. The overall structure is simpler. Compared with the electronically controlled semi-active stabilizer bar solution in the related art, the stabilizer bar 100 in the embodiment of the present invention can be operated on any road surface and is not affected by the environment. At the same time, the structure is simplified. Compared with the related art, there is no noise problem when the gears rotate, thereby reducing vehicle noise.
