Description

Technical Field

[0001] This utility model relates to the field of automotive control arm technology, and in particular to a control arm structure that improves the overall performance of an open bushing. Background Technology

[0002] In automotive suspension systems, control arm bushings play a crucial role, directly impacting vehicle stability, handling, and safety. However, current open-end control arm bushings exhibit numerous problems in practical applications. Firstly, after press-fitting and closing, the inner tube of the bushing lacks sufficient strength, leading to easy wear over long-term use and difficulty maintaining stable press-out force. This can cause bushing loosening, severely affecting suspension system performance and even posing safety hazards. Secondly, the open end of the bushing is prone to deformation under the complex stresses of vehicle operation, further reducing its reliability and lifespan. Therefore, an innovative structural design is urgently needed to effectively address these issues and improve the overall performance of control arm bushings. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a control arm structure that improves the overall performance of open bushings. Multiple reinforcing ribs are provided on the outer wall of each end of the inner tube. By increasing the strength of the inner tube end through the reinforcing ribs, the bushing pressing force can be effectively improved, and the vibration resistance performance can be improved. An embossed plane is arranged on the control arm body at the port in front of the assembly hole. Multiple embossed dimples are evenly arranged around the outer tube on the embossed plane. The evenly distributed embossed dimples can effectively improve multi-directional vibration and impact, and effectively reduce stress distribution problems. The embossed plane facilitates the processing of embossed dimples and reduces processing costs.

[0004] The technical solution adopted by this utility model to solve its technical problem is: to provide a control arm structure that improves the overall performance of an open bushing, including a control arm body and a bushing. The front end of the control arm body is provided with an assembly hole for accommodating the bushing. The bushing includes an outer tube installed in the assembly hole, an inner tube disposed in the outer tube, and rubber disposed between the inner tube and the outer tube. Both ends of the inner tube extend out of the outer tube, and multiple reinforcing ribs are provided on the outer side wall of each end of the inner tube. An embossed plane is arranged on the control arm body at the front port of the assembly hole. Multiple embossed recesses are evenly arranged around the outer tube on the embossed plane. One end of each embossed recess is connected to the inner wall of the assembly hole.

[0005] As a supplement to the technical solution described in this utility model, eight evenly distributed embossing indentations are provided on the embossed surface.

[0006] As a supplement to the technical solution described in this utility model, each of the embossed recesses is a square groove with a length of 4-5mm, a width of 3-4mm, and a depth of 1-1.5mm.

[0018] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0019] The embodiments of this utility model relate to a control arm structure that improves the overall performance of open bushings, such as... Figure 1-6 As shown, the device includes a control arm body 1 and a bushing 2. The control arm body 1 has an assembly hole 3 at its front end to accommodate the bushing 2. The bushing 2 includes an outer tube 21 installed in the assembly hole 3, an inner tube 22 disposed within the outer tube 21, and a rubber 23 disposed between the inner tube 22 and the outer tube 21. Both ends of the inner tube 22 extend beyond the outer tube 21, and multiple reinforcing ribs 221 are provided on the outer side wall of each end of the inner tube 22. The reinforcing ribs 221 increase the strength of the end of the inner tube 22, effectively improving its strength. The bushing pressing force is reduced, and the vibration resistance is improved. The control arm body 1 has a ring of embossed plane 11 at the front port of the assembly hole 3. Multiple embossed dimples 111 are evenly arranged around the outer tube 21 on the embossed plane 11. The evenly distributed embossed dimples 111 can effectively reduce multi-directional vibration impact and reduce stress distribution problems. The embossed plane 11 facilitates the processing of the embossed dimples 111 and reduces processing costs. One end of the embossed dimple 111 is connected to the inner wall of the assembly hole 3.

[0020] In this embodiment, as Figure 2 As shown, the embossed plane 11 is provided with eight evenly distributed embossed dimples 111. The evenly distributed embossed dimples 111 can effectively reduce stress distribution problems.

[0021] In this embodiment, as Figure 2 As shown, each of the embossed indentations 111 is a square groove with a length of 4-5mm, a width of 3-4mm, and a depth of 1-1.5mm. The edge spacing between adjacent embossed indentations 111 is ≥10mm, effectively buffering dynamic impacts during driving.

[0022] In this embodiment, as Figure 2As shown, the thickness of the reinforcing rib 221 is 1.0-1.5mm, and the width of the reinforcing rib 221 is 2-4mm. The setting of the reinforcing rib 221 can effectively improve the stability of the inner tube 22. The specifications of the above-mentioned reinforcing rib 221 have been tested and found to be quite good.

[0023] In this embodiment, as Figure 4 and Figure 5 As shown, the rear end of the assembly hole 3 is provided with a reduced diameter anti-slip opening 12. The outer tube 21 has an overall structure that is thick in the middle and thin at both ends. The outer tube 21 has a protruding ring 211 in the middle. During installation, the outer tube 21 is inserted from the front end of the assembly hole 3 so that the protruding ring 211 and the anti-slip opening 12 are engaged, so that it is installed in place during use and the positioning is stable.

[0024] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0025] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0026] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
