Description

Technical Field

[0001] The invention belongs to the technical field of automobile suspension structures, and in particular relates to a ball head seat used in an automobile suspension system. Background Art

[0002] The automobile suspension system is one of the key components to ensure the driving stability and ride comfort of the vehicle. As an important part of the suspension system, the ball head seat connects the steering knuckle with the control arm or other components, and bears various impacts and loads from the road. The traditional ball head seat design usually includes a fixed seat body and a rotatable ball shaft, which realizes free rotation in multiple directions through the spherical contact surface. However, this traditional design is prone to wear on the contact surface between the ball shaft and the seat body under long-term use or under the action of large external forces. At the same time, the traditional ball head seat design lacks an effective buffer design. When the vehicle is driving on a bumpy road, the ball shaft will directly bear the impact force, resulting in greater stress on the internal structure of the ball head seat, thereby accelerating material fatigue and damage, and may also cause the ball head seat to fail, thereby affecting the performance of the entire suspension system.

[0003] Therefore, based on some of the above prior art situations, the present application has been further designed and improved. Summary of the invention

[0004] In order to solve the above technical problems, the present invention is solved by the following technical solutions.

[0005] A ball head seat for an automobile suspension system comprises a seat body and a ball shaft, wherein the seat body is provided with an assembly cavity and an assembly opening for the ball shaft to extend into the assembly cavity, wherein an assembly block is provided in the assembly cavity, wherein a spherical groove is provided on the assembly block, and wherein the ball shaft is assembled in the spherical groove; wherein limit sliders are provided on the front and rear sides of the assembly block, wherein a slide groove cooperating with the limit slider is provided on the inner wall of the assembly cavity, and wherein a spring is provided at the bottom of the limit slider. By assembling a spring at the bottom of the limit slider, when the ball shaft is impacted, the assembly block can automatically adjust its position, thereby reducing the wear caused by direct impact. This design not only improves the service life of the ball head seat, but also ensures the stability and comfort of the automobile suspension system.

[0006] As a preferred technical solution for the ball head seat of the automobile suspension system, the assembly block is equipped with a limit plate to limit the ball shaft from leaving the spherical groove, and the left and right sides of the assembly block are provided with limit blocks for limiting the limit plate. Such a double insurance mechanism effectively prevents the ball shaft from accidentally falling out due to external force, and enhances the safety performance of the entire structure.

[0007] As a preferred technical solution for a ball head seat for an automobile suspension system, the seat body includes an assembly seat and a shell, the assembly seat and the shell cooperate to form an assembly cavity, and compression blocks are installed on both sides of the shell, the compression blocks extend into the assembly cavity and abut against the limit blocks. This design can press the limit plate tightly against the assembly block, reducing the loosening of the limit plate caused by vibration and other reasons, thereby reducing the loosening of the ball shaft, and further improving the reliability and durability of the product.

[0008] As a preferred technical solution for a ball head seat for an automobile suspension system, the length of the limit slider is greater than the width, and the width of the limit slider is equal to the width of the limit slot. This can ensure that the assembly block moves smoothly along the predetermined track and avoid unnecessary shaking or jamming, thus achieving a balance between precise positioning and smooth movement.

[0009] As a preferred technical solution for a ball head seat for an automobile suspension system, it also includes a dust cover, which is sleeved and assembled with the ball shaft, one end of the dust cover is assembled on the ball shaft, and the other end of the dust cover is assembled at the assembly port. The dust cover can prevent external pollutants such as dust and moisture from entering the assembly cavity to damage the surface of the parts, and can also buffer the impact of external impact on the ball shaft to a certain extent, thereby extending the overall service life of the component. At the same time, a good sealing effect is also conducive to maintaining the lubrication state and reducing friction loss.

[0010] Compared with the prior art, the present application has the following beneficial effects: the movable design of the assembly block assembled with the ball shaft can greatly reduce the problems of wear or component deformation caused by direct impact. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Reference Figures 1 to 5 A ball head seat for automobile suspension system, comprising a seat body 100 and a ball shaft 200, wherein the seat body 100 is provided with an assembly cavity 101 and an assembly opening 102 for the ball shaft 200 to extend into the assembly cavity 101, wherein an assembly block 111 is provided in the assembly cavity 101, wherein the assembly block 111 is provided with a spherical groove, wherein the ball shaft 200 is assembled in the spherical groove; wherein limit sliders 112 are provided at the front and rear sides of the assembly block 111, wherein a slide groove 103 cooperating with the limit slider 112 is provided on the inner wall of the assembly cavity 101, wherein a spring 130 is provided at the bottom of the limit slider 112. By assembling the spring 130 at the bottom of the limit slider 112, when the ball shaft 200 is impacted, the assembly block 111 can automatically adjust its position, thereby reducing the wear caused by direct impact. This design not only improves the service life of the ball head seat, but also ensures the stability and comfort of the automobile suspension system.

[0023] In order to further improve the performance and adaptability of the ball head seat, the assembly block 111 is made of a metal alloy with high hardness and low friction coefficient, which can not only ensure sufficient strength to support the ball shaft 200 and disperse the load, but also reduce the wear between the moving parts and extend the service life. At the same time, the key parts that are subjected to large stress, such as the contact surface between the limit slider 112 and the slide groove 103, are surface hardened to enhance their wear resistance and fatigue resistance.

[0024] Furthermore, the assembly block 111 is equipped with a limit plate 140 for limiting the ball shaft 200 from escaping from the spherical groove, and the assembly block 111 is provided with limit blocks 113 on the left and right sides for limiting the limit plate 140. Such a double insurance mechanism effectively prevents the ball shaft 200 from accidentally coming out due to external force, thereby enhancing the safety performance of the entire structure. For the convenience of assembly, the seat body 100 includes an assembly seat 110 and a shell 120, wherein the assembly seat 110 and the shell 120 cooperate to form an assembly cavity 101, and clamping blocks 121 are installed on both sides of the shell 120, wherein the clamping blocks 121 extend into the assembly cavity 101 and abut against the limit blocks 113. This design can press the limit plate 140 tightly against the assembly block 111, thereby reducing the loosening of the limit plate 140 caused by vibration and the like, thereby reducing the loosening of the ball shaft 200, thereby further improving the reliability and durability of the product. Taking into account the space limitations that may be encountered during the actual installation process, the bottom of the clamping block 121 in the present invention is equipped with an elastic pad, which can adjust the clamping force within a certain range to flexibly cope with the subtle differences that may exist between different car models or different versions of the same car model, thereby greatly improving the product's scope of application.

[0025] Furthermore, the length of the limit slider 112 is greater than the width, and the width of the limit slider 112 is equal to the width of the limit slot 103. This can ensure that the assembly block 111 moves smoothly along the predetermined track, and avoid unnecessary shaking or jamming problems, thus achieving a balance between precise positioning and smooth movement. Considering various complex conditions that may exist in actual application scenarios, such as temperature changes, humidity influences and other factors, the limit slider 112 is surface hardened to enhance its wear resistance and fatigue resistance, ensuring that even in extreme environments, the device can still maintain its proper function and accuracy.

[0026] Furthermore, the present application also includes a dust cover 210, which is sleeved and assembled with the ball shaft 200, one end of the dust cover 210 is assembled on the ball shaft 200, and the other end of the dust cover 210 is assembled at the assembly port 102. The dust cover 210 can prevent external pollutants such as dust and moisture from entering the assembly cavity 101 to damage the surface of the parts, and can also buffer the impact of external impact forces on the ball shaft 200 to a certain extent, thereby extending the overall service life of the component. At the same time, a good sealing effect is also conducive to maintaining a lubricated state and reducing friction loss. Among them, the dust cover 210 is made of high-performance rubber material that is resistant to aging and tearing, and a layer of special lubricant is coated on its inner side, which not only provides a better sealing effect, but also helps to reduce the friction resistance when the ball shaft 200 rotates, thereby further reducing energy loss and improving overall efficiency.

[0027] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention shall be based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present invention.
