Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive universal control arm technology, and in particular to an automotive universal control arm mechanism. Background Technology
[0002] The control arm (also known as the swing arm) is a key component of a car's suspension system. It is responsible for transmitting various forces from the wheels to the vehicle body and ensuring that the wheels move stably along a predetermined trajectory. The control arm is connected to the wheels and the vehicle body via ball joints or bushings, providing a flexible connection while ensuring the rigidity and strength of the connection, as well as a long service life.
[0003] The control arm bushing is an important component of the suspension system, playing a role in cushioning and stabilizing the vehicle, reducing vibration and noise when driving on uneven roads. As the vehicle ages and mileage increases, the control arm bushing may gradually age, crack, or even fall off. Current control arm bushings are pressed into the control arm through a stamping process. When the control arm bushing ages or cracks and needs replacement, it is difficult to remove the bushing from the control arm without specialized stamping equipment.
[0004] Therefore, we propose a universal automotive control arm mechanism to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a universal control arm mechanism for automobiles.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A universal automotive control arm mechanism includes an annular outer peripheral plate. Annular base plates are fixedly connected to both ends of the annular outer peripheral plate. Two first support plates, arranged symmetrically to the left and right, are fixedly connected between the two annular base plates. A threaded rod is rotatably connected between the two first support plates. A first bevel gear is rotatably connected to the end of one of the first support plates away from the other. The first bevel gear is coaxially fixedly connected to the threaded rod. A rotating rod passes through and rotatably connects to the annular outer peripheral plate. A second bevel gear is fixedly connected to the lower end of the rotating rod, and the second bevel gear meshes with the first bevel gear. A knob is fixedly connected to the upper end of the rotating rod.
[0008] Preferably, the threaded rod is provided with two L-shaped blocks arranged symmetrically on the left and right sides. The L-shaped block on the left side is threadedly fitted onto the threaded part of the threaded rod, and the L-shaped block on the right side is rotatably fitted onto the unthreaded part of the threaded rod. A rectangular rod is fixedly connected to the left end of the first support plate on the right side, and two fixing blocks are fixedly fitted onto the rectangular rod. The two fixing blocks are located at the left and right ends of the L-shaped block on the right side, respectively.
[0009] Preferably, each of the two L-shaped blocks has a connecting block fixedly connected to one end of each block that is close to the other, and a semi-circular block fixedly connected to the lower end of each of the two connecting blocks. The two semi-circular blocks are symmetrically arranged. Two second support plates, which are arranged on the left and right sides respectively, are fixedly connected together between the two annular base plates. A sliding rod is fixedly connected together between the two second support plates. A sliding plate is fixedly connected to the lower end of each of the two semi-circular blocks. The two sliding plates are slidably sleeved on the sliding rod.
[0010] Preferably, both connecting blocks and both sliding plates are provided with fastening mechanisms, the fastening including bolts, wedge-shaped washers are fitted on the bolts, and nuts are threaded onto the bolts.
[0011] Preferably, a rubber sleeve is provided between the two semicircular blocks.
[0012] Preferably, the right end of the semicircular block on the right side is fixedly connected to the main body of the control arm, which penetrates the annular outer peripheral plate.
[0013] Compared with existing technologies, the advantages of this device are:
[0014] 1. By rotating the knob, the L-shaped block on the left side of the threaded rod moves to the left, causing the semicircular block on the left side to move to the left, thus separating the two semicircular blocks and easily removing the rubber sleeve. Unlike traditional control walls, it does not require professional equipment to remove the rubber sleeve.
[0015] 2. The wedge-shaped gasket is locked by a mechanical mechanism, which can effectively prevent the bolts and nuts from loosening due to vibration, making the structure more robust.
[0016] In summary, this utility model has a robust structure. When the rubber sleeve needs to be replaced due to aging or cracking, it can be easily removed without the need for specialized equipment as required by traditional control walls. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figures 1-3 A universal automotive control arm mechanism includes an annular outer peripheral plate 1. Annular base plates 2 are fixedly connected to both ends of the annular outer peripheral plate 1. Two first support plates 3, arranged left and right, are fixedly connected between the two annular base plates 2. A threaded rod 4 is rotatably connected between the two first support plates 3. A first bevel gear 5 is rotatably connected to the end of one first support plate 3 away from the other. The first bevel gear 5 is coaxially fixedly connected to the threaded rod 4. A rotating rod 6 passes through and rotatably connects to the annular outer peripheral plate 1. A second bevel gear 7 is fixedly connected to the lower end of the rotating rod 6. The second bevel gear 7 meshes with the first bevel gear 5. A knob 8 is fixedly connected to the upper end of the rotating rod 6. Rotating the knob 8 causes the rotating rod 6 to rotate, which in turn causes the second bevel gear 7 to rotate. The second bevel gear 7 then drives the first bevel gear 5, which meshes with it, to rotate, thereby causing the threaded rod 4 to rotate.
[0023] The threaded rod 4 is provided with two L-shaped blocks 9 arranged symmetrically on the left and right. The L-shaped block 9 on the left is threaded onto the threaded part of the threaded rod 4, and the L-shaped block 9 on the right is rotatably fitted onto the unthreaded part of the threaded rod 4. A rectangular rod 10 is fixedly connected to the left end of the first support plate 3 on the right side. Two fixing blocks 11 are fixedly fitted on the rectangular rod 10. The two fixing blocks 11 are located at the left and right ends of the L-shaped block 9 on the right side, respectively. The L-shaped block 9 slides against the two annular base plates 2. Under the limitation of the two annular base plates 2, when the threaded rod 4 rotates, the L-shaped block 9 on the left side, which is threaded onto the threaded part of the threaded rod 4, can move to the left or right, while the L-shaped block 9 on the right side is fixed in its original position under the limitation of the rectangular rod 10 and the two fixing blocks 11.
[0024] Two L-shaped blocks are fixedly connected to one end of each other with a connecting block 12. The lower ends of the two connecting blocks 12 are fixedly connected to a semi-circular block 13. The two semi-circular blocks 13 are symmetrically arranged. Two second support plates 14 are fixedly connected between the two annular base plates 2. A sliding rod 15 is fixedly connected between the two second support plates 14. The lower ends of the two semi-circular blocks 13 are fixedly connected to a sliding plate 16. The two sliding plates 16 are slidably sleeved on the sliding rod 15.
[0025] By moving the L-shaped block 9 on the left to the right, the two semicircular blocks 13 can be spliced into a ring block. Fastening mechanisms are provided on the two connecting blocks 12 and the two sliding plates 16. The fastening includes bolts 17, with wedge-shaped washers 18 fitted on the bolts 17 and nuts 19 threaded onto the bolts 17. A rubber sleeve 20 is provided between the two semicircular blocks 13. The two semicircular blocks 13 can be spliced into a ring block. The bolts 17 in the two fastening mechanisms pass through the two connecting blocks 12 and the two sliding plates 16 respectively. By tightening the bolts 17 and nuts 19 in the two fastening mechanisms, the ring block formed by the spliced two semicircular blocks 13 is fastened, thereby clamping the rubber sleeve 20. The wedge-shaped washers 18 are locked by a mechanical mechanism, effectively preventing the bolts 17 and nuts 19 from loosening due to vibration. The wedge-shaped washers 18 are existing technology, and their specific working principle will not be described in detail here.
[0026] The right end of the semicircular block 13 located on the right side is fixedly connected to the main body 21 of the control arm, which passes through the annular outer peripheral plate 1.
[0027] When using this utility model, the two semicircular blocks 13 are fastened together to form a ring block by two fastening mechanisms, thereby clamping the rubber sleeve 20. The wedge-shaped gasket 18 is locked by a mechanical mechanism, which can effectively prevent the bolts 17 and nuts 19 from loosening due to vibration. When the rubber sleeve 20 needs to be replaced due to aging, cracking, etc., the bolts 17 and nuts 19 in the two neck bone mechanisms are loosened. By rotating the knob 8, the L-shaped block 9 located on the left side of the threaded part of the threaded rod 4 moves to the left, which drives the semicircular block 13 located on the left side to move to the left, thereby separating the two semicircular blocks 13. The rubber sleeve 20 can then be easily removed without the need for professional equipment as with traditional control walls.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
