Description

Technical Field

[0001] This utility model belongs to the field of control arm bushing technology. Specifically, this utility model relates to a control arm assembly with adjustable bushing direction. Background Technology

[0002] Currently, both the control arm bushings and the control arm body of passenger vehicle chassis suspensions adopt an interference fit structure.

[0003] A patent application with patent number 201720661200.0, published on February 6, 2018, discloses a control arm bushing. The bushing includes an inner tube, an outer tube, a central skeleton disposed between the inner and outer tubes, and a rubber component vulcanized on the central skeleton and bonded to both the inner and outer tubes. The central skeleton has an inlet hole for the rubber to enter. This invention, by providing an inlet hole on the central skeleton to connect the rubber component, improves the pull-out force of the rubber, thereby enhancing the bushing's durability and axial pull-out force.

[0004] Currently, bushings with interference fit structures cannot have their assembly angles changed quickly and easily. When it is necessary to change the bushing angle to change the bushing stiffness for purposes such as chassis adjustment, special equipment is required to replace the bushing, which is inconvenient to operate and may also cause some damage to the control arm body. Utility Model Content

[0005] The present invention aims to provide a bushing direction adjustable control arm assembly that can quickly adjust the bushing stiffness direction and save adjustment time.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a control arm assembly with adjustable bushing direction, including an outer sleeve disposed inside the control arm, an adjusting shim that cooperates with the outer sleeve at the end of the outer sleeve, and a locking cover plate for fixing on the adjusting shim.

[0007] The ends of the outer tube and the adjusting shim are toothed, and the ends of the outer tube and the adjusting shim are engaged.

[0008] The outer sleeve is provided with an inner sleeve on the inside.

[0009] A rubber bushing is provided between the outer sleeve and the inner sleeve.

[0010] The outer sleeve and inner sleeve are assembled in a vulcanization mold, and the outer sleeve, inner sleeve and bushing rubber are connected by a vulcanization process.

[0011] The adjusting shim and the locking cover are connected by threads.

[0012] The outer surface of the adjusting shim is conical, and the inner surface of the locking cover is conical.

[0013] The locking cover is located on both sides of the control arm.

[0014] The locking cover plate is divided into a ring and a cylinder, with threads on the outer surface of the cylinder.

[0015] The technical advantages of this invention are as follows: during the vehicle chassis tuning process, the bushing angle can be adjusted, the bushing hollow direction can be changed, and the bushing stiffness direction can be quickly adjusted, saving the tuning cycle. Vehicle users can also change the bushing direction according to their needs, providing customers with a space for independent choice and enhancing the driving experience.

[0026] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution, and to facilitate its implementation.

[0027] Please see Figure 1-8 A bushing-direction adjustable control arm assembly includes an outer sleeve 2 disposed within a control arm 1. An adjusting shim 3, which mates with the end of the outer sleeve 2, is provided at its end. A locking cover 4 is provided on the adjusting shim 3 for fixing. By utilizing the interaction between the outer sleeve 2 and the adjusting shim 3, the angle of the bushing can be adjusted. The locking cover 4 secures the outer sleeve 2 and the adjusting shim 3 within the control arm 1. During vehicle chassis tuning, the bushing angle can be adjusted, the bushing hollow direction can be changed, and the bushing stiffness direction can be quickly adjusted, saving tuning time. Vehicle users can also change the bushing direction according to their needs, providing them with a choice and enhancing the driving experience.

[0028] The ends of the outer tube 2 and the adjusting shim 3 are toothed, and the ends of the outer tube 2 and the adjusting shim 3 are engaged. The toothed ends can be used to fix and lock each other in place, and can also be used to adjust the angle. The teeth can be used to quickly fix the angle after adjustment.

[0029] The inner sleeve 5 is provided on the inner side of the outer sleeve 2; the inner sleeve 5 is usually a steel or aluminum tube.

[0030] A bushing rubber 6 is provided between the outer sleeve 2 and the inner sleeve 5; the bushing rubber 6 is usually made of natural rubber or neoprene rubber, and the cross-section of the bushing rubber 6 is arc-shaped, which is used to absorb shock and reduce the application and release of pressure.

[0031] The outer sleeve 2 and the inner sleeve 5 are assembled in a vulcanization mold. The outer sleeve 2, the inner sleeve 5 and the bushing rubber 6 are connected by a vulcanization process. This process can enhance the elasticity, hardness and other properties of the bushing rubber 6, effectively improve the performance of the bushing rubber 6, and improve its moldability, so that the bushing rubber 6 can fit more tightly with the outer sleeve 2 and the inner sleeve 5.

[0032] The adjusting shim 3 and the locking cover 4 are connected by threads; the threaded connection facilitates installation and disassembly.

[0033] The outer surface of the adjusting shim 3 is conical, and the inner surface of the locking cover plate 4 is conical; the taper is 1:6. The conical fit makes the threaded connection tighter and easier to tighten.

[0034] Locking cover 4 is located on both sides of control arm 1; the locking cover 4 is used to fix the bushing inside control arm 1, and it is also convenient for personnel to remove the locking cover 4.

[0035] The locking cover plate 4 is divided into a ring and a cylinder, with threads set on the outer surface of the cylinder; the outer ring can cover the inner bushing structure, increasing aesthetics.

[0036] The technical advantages of this invention are as follows: during the vehicle chassis tuning process, the bushing angle can be adjusted, the bushing hollow direction can be changed, and the bushing stiffness direction can be quickly adjusted, saving the tuning cycle. Vehicle users can also change the bushing direction according to their needs, providing customers with a space for independent choice and enhancing the driving experience.

[0037] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
