Technical Field
[0001] This utility model relates to the field of automotive parts technology, and more specifically, to an automotive control arm assembly. Background Technology
[0002] The suspension is a general term for the force transmission connection device between the car wheels and the car body. The suspension includes elastic elements, shock absorbers and force transmission devices. The force transmission devices include control arms, tie rods and stabilizer bars, etc. However, the control arm assembly and the installed rubber bushing are limited by the bushing boss in actual use, and its limiting strength is insufficient. In addition, after the bushing is connected to the connecting rod, the anti-slip part restricts the rotation of the connecting rod's threaded sleeve, which is not stable enough and reduces the safety of connection and use.
[0003] For example, CN220594568U discloses an automotive control arm assembly. This automotive control arm assembly includes an arm body, on which a ball joint assembly, a rubber sleeve assembly, and a bushing assembly are connected. The rubber sleeve assembly includes an inner tube, an outer tube, and an elastomer. The elastomer is fixed between the inner tube and the outer tube, and the length of the inner tube is greater than the length of the outer tube.
[0004] As can be seen from the above-disclosed scheme, the rubber sleeve assembly is connected to the arm body through an elastomer. Due to the insufficient resistance to compression and impact of the elastomer, the elastomer will become thinner under the mutual tension between the connecting rod and the arm body, which will lead to a larger gap at the connection and thus cause it to fall off, reducing the stability of the rubber sleeve in use. Furthermore, the rubber sleeve assembly uses the first anti-slip tooth to prevent the threaded sleeve on the surface of the connecting rod from rotating automatically, but its limiting effect is poor. It may cause the threaded sleeve to rotate automatically due to vibration or strip and loosen, thereby reducing the connection safety of the connecting rod. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1: Please refer to Figure 1-4A vehicle control arm assembly includes a control arm assembly body 1. The specific shape, dimensions, and manufacturing method of the control arm assembly body 1 are well known to those skilled in the art and belong to the prior art. The surface of the control arm assembly body 1 is provided with weight reduction holes 11, a ball joint assembly 2, a bushing assembly 3, and a rubber sleeve 5. The composition and working principle of the ball joint assembly 2 and the bushing assembly 3 are well known to those skilled in the art and will not be described in detail here. A reinforcing sleeve 51 is provided on the outer side of the rubber sleeve 5. The material and manufacturing method of the rubber sleeve 5 are prior art. A connecting rod 6 is connected to the inner wall of the rubber sleeve 5. The surface of the connecting rod 6 is connected to a first fastening sleeve 7 and a second fastening sleeve 8 by threads. The first fastening sleeve 7 and the second fastening sleeve 8 are used to connect and fix the connecting rod 6 to the rubber sleeve assembly, and then to the control arm assembly body 1, to ensure... To ensure the stability of the control arm assembly, both the first fastening sleeve 7 and the second fastening sleeve 8 are provided with connecting parts 71. A connecting hole 72 is provided at the center of the connecting part 71. An anti-detachment block 73 is fixedly connected to the outer surface of the connecting part 71. One end of the first fastening sleeve 7 and the second fastening sleeve 8 is in contact with and pressed against an anti-detachment sleeve 4. One end of the anti-detachment sleeve 4 is fixedly connected to a reinforcing part 12. Both ends of the rubber sleeve 5 and the reinforcing sleeve 51 are provided with folded edges. The folded edges are circular. One end of the anti-detachment sleeve 4 is provided with an anti-detachment groove 41. One end of the anti-detachment groove 41 is provided with an anti-detachment cover plate. The opening 42 is located inside the cover plate. The cover plate is made of elastic stainless steel and has serrations on its surface. This not only increases the friction but also allows the opening 42 to have an elastic deformation function, making it easy for the user to control the anti-detachment block 73 to move in and out of the anti-detachment groove 41 when rotating.
[0025] The inner wall of the anti-detachment groove 41 is connected to an opening 42. The anti-detachment block 73 is located inside the anti-detachment groove 41. There is a gap between one end of the anti-detachment block 73 and the inner wall of the anti-detachment groove 41. Both the anti-detachment block 73 and the opening 42 are rectangular in shape. The anti-detachment block 73 can only enter the anti-detachment groove 41 through the opening 42, so that the connecting part 71 of the first fastening sleeve 7 and the second fastening sleeve 8 will not arbitrarily detach from the anti-detachment groove 41. The surface of the connecting rod 6 is provided with a connecting thread 61. The inner wall of the connecting hole 72 is provided with an internal thread that matches the connecting thread 61. The surface of the connecting thread 61 contacts and presses against the inner wall of the rubber sleeve 5, so that the connecting rod 6 can be connected and fixed to the control arm assembly 1 through the two fastening sleeves.
[0026] A limiting groove 43 is provided at the bottom center of the anti-detachment groove 41. The inner wall of the limiting groove 43 contacts and presses against the surface of the reinforcing sleeve 51. A center hole 44 is provided at the bottom center of the limiting groove 43. The limiting groove 43 can limit the position of both ends of the rubber sleeve 5 and the reinforcing sleeve 51, ensuring the installation stability and firmness of the rubber sleeve assembly. The end face of the rubber sleeve 5 is within the limiting groove 43. The inner diameter of the limiting groove 43 is larger than the outer diameter of the connecting part 71. One end of the connecting part 71 contacts and presses against the end face of the rubber sleeve 5. The inner wall of the center hole 44 contacts and connects with the side of the reinforcing sleeve 51. The reinforcing sleeve 51 is made of metal material, ensuring the connection strength and support strength of the rubber sleeve assembly.
[0027] When installing the control arm assembly body 1 and the connecting rod 6, one end of the connecting rod 6 is first passed through the rubber sleeve 5. Then, the first fastening sleeve 7 and the second fastening sleeve 8 are threaded together from both ends of the connecting rod 6. At this time, the first fastening sleeve 7 rotates clockwise and the second fastening sleeve 8 rotates counterclockwise, causing the first fastening sleeve 7 and the second fastening sleeve 8 to move closer to each other. This brings the connecting part 71 closer to the two anti-detachment sleeves 4. Under the control of the number of turns of the connecting thread 61, the anti-detachment block 73 is screwed into the limiting groove 43 through the opening 42 and continues to rotate, thereby bringing the end face of the connecting part 71 closer to the end of the rubber sleeve 5. The surface contacts and presses together, and the end faces of the first fastening sleeve 7 and the second fastening sleeve 8 contact and press with the end face of the anti-detachment sleeve 4 to complete the action. The reinforcement part 12, the anti-detachment sleeve 4 and the reinforcement sleeve 51 can greatly increase the connection stability and firmness between the rubber sleeve 5 and the control unit 1, effectively improving the stability of the rubber sleeve 5. Furthermore, the anti-detachment blocks 73 set in the two fastening sleeves and the anti-detachment grooves 41 set in the two anti-detachment sleeves 4 can prevent the fastening sleeves from loosening due to vibration rotation or stripping, thereby preventing the connecting rod 6 from separating from the control unit 1, greatly improving the connection safety of the connecting rod 6.
