Description

Technical Field

[0001] This utility model relates to the field of automotive suspension technology, specifically an automotive suspension spring assembly. Background Technology

[0002] Automotive suspension spring assemblies refer to the collective term for elastic elements and their related support structures in a vehicle's suspension system used to store, release, and absorb energy. They are not only key components connecting the vehicle body and wheels, but also directly determine the vehicle's ride comfort, handling stability, and safety. When a vehicle travels on uneven roads, the springs absorb the impact energy from the road surface through their own deformation, reducing the impact force transmitted to the vehicle body. They operate based on the principle of elastic deformation—when subjected to external force, they deform and store potential energy; after the external force is removed, they return to their original shape and release energy. In the suspension system, this process repeats continuously, transforming concentrated and severe impacts into smooth and continuous vibrations.

[0003] Regarding the aforementioned technologies: Automotive suspension spring assemblies mainly consist of shock absorbers and buffer springs hinged to the lower control arm. They filter vibrations and bumps generated by the wheels during driving, making the vehicle smoother and reducing the force of vibration transmitted to the passenger compartment. The springs are directly fitted onto the outside of the shock absorber. When the vehicle is on muddy or even mountainous roads, flying stones and mud may adhere to the piston rod of the shock absorber. As the shock absorber extends and contracts, the piston cylinder will rub against the mud adhering to the piston rod, affecting the service life of the shock absorber.

[0004] Therefore, this utility model provides an automotive suspension spring assembly to solve the above-mentioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automotive suspension spring assembly that solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an automotive suspension spring assembly, including a lower control arm, which is composed of a V-arm and an extension arm. The right end of the V-arm is fixedly connected to one end of the extension arm. An internal support structure for strengthening the structural strength of the lower control arm is installed inside the V-arm, and a spring mechanism is installed at the top of the extension arm. The spring mechanism includes a hinge seat fixedly mounted on the top of the extended arm, a connecting seat hinged to the inner wall of the hinge seat, two fixed seats arranged symmetrically above and below the connecting seat on the top wall, and a hinge joint for hinged mounting with the frame on the top wall of the fixed seat located at the top. Shock absorbers are installed between the fixed seats, buffer springs are installed between the fixed seats and outside the shock absorbers, and telescopic sleeves are installed between the fixed seats and outside the shock absorbers. The telescopic sleeves are located inside the buffer springs, and telescopic protective sleeves are installed on the outer walls of the telescopic sleeves.

[0007] Through the above technical solution, the spring mechanism can provide stable protection for the shock absorber and buffer spring, preventing structural friction caused by mud and stones adhering to them.

[0008] Furthermore, the internal support structure includes a primary internal support frame and a secondary internal support frame.

[0009] Through the above technical solutions, the primary and secondary inner support frames can mainly strengthen the internal structure of the V-arm, thereby providing a stabilizing effect on the entire vehicle suspension.

[0010] Furthermore, the primary inner support is fixed to the outer end of the inner wall of the V-arm, and the secondary inner support is fixedly installed at the included angle of the inner wall of the V-arm.

[0011] Through the above technical solution, both the primary and secondary internal support frames provide multi-point support for the interior of the V-arm.

[0012] Furthermore, reinforcing members are fixedly installed between the primary and secondary internal support frames, with the right end of the reinforcing member extending to the angle of the inner wall of the V-shaped arm for fixation.

[0013] Through the above technical solution, the reinforcing components are simultaneously used to connect the primary and secondary internal support frames for comprehensive stress distribution.

[0014] Furthermore, the primary inner support frame, the secondary inner support frame, and the reinforcing members are all located below the top wall of the V-arm, and the top wall of the V-arm is provided with a drainage groove.

[0015] The drainage channel, as described above, is mainly used to drain water that may accumulate on the top wall of the V-arm (which may accumulate on rainy days or when washing the car).

[0016] Furthermore, a connecting cylinder is fixedly installed at the outer end of each V-arm, and a connecting shaft is rotatably installed on the inner wall of each connecting cylinder. An installation shaft is rotatably installed inside the extended arm.

[0017] With the above technical solution, both the connecting cylinder and the mounting shaft are rotatably connected to the vehicle suspension, thereby maintaining the structural connection stability. Beneficial effects

[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. 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.

[0022] Example 1: Please see Figures 1-4 A car suspension spring assembly includes a lower control arm 1, which is composed of a V-arm 2 and an extension arm 3.

An inner support structure 5 for reinforcing the structural strength of the lower control arm 1 is installed inside the V-arm 2. A spring mechanism 7 is installed at the top of the extension arm 3. The spring mechanism 7 includes a hinge seat 71 fixedly installed on the top of the extended arm 3. A connecting seat 72 is hingedly installed on the inner wall of the hinge seat 71. Two fixed seats 74 are symmetrically arranged on the top wall of the connecting seat 72. A hinge joint 73 for hinged installation with the frame is installed on the top wall of the fixed seat 74 located at the top. A shock absorber 76 is provided between the fixed seats 74. A buffer spring 75 is installed between the fixed seats 74 and sleeved on the outside of the shock absorber 76. A telescopic sleeve 77 is installed between the fixed seats 74 and sleeved on the outside of the shock absorber 76. The telescopic sleeve 77 is located inside the buffer spring 75. A telescopic protective sleeve 78 is installed on the outer wall of the telescopic sleeve 77. In this embodiment of the utility model, the purpose of this arrangement is that the spring mechanism 7 can protect the outside of the shock absorber 76. By setting the telescopic sleeve 77 and the telescopic protective sleeve 78, it prevents stones or mud from adhering to the piston rod of the shock absorber 76 after the car has passed through muddy roads, which would cause serious friction when the shock absorber 76 is extended and retracted. This has the effect of stabilizing the operation of the shock absorber 76 and extending its service life.

[0023] Example 2: Please see Figures 1-4 This embodiment provides a technical solution based on embodiment one: the inner support structure 5 includes a primary inner support frame 51 and a secondary inner support frame 52. The primary inner support frame 51 and the secondary inner support frame 52 are arranged symmetrically on the left and right and are fixedly connected to the inner wall of the V-shaped arm 2. The length of the primary inner support frame 51 is greater than that of the secondary inner support frame 52. The primary inner support frame 51 is fixed at the outer end of the inner wall of the V-shaped arm 2. The secondary inner support frame 52 is fixedly installed at the included angle of the inner wall of the V-shaped arm 2. A reinforcing member 53 is fixedly installed between the primary inner support frame 51 and the secondary inner support frame 52. The right end of the reinforcing member 53 extends to the included angle of the inner wall of the V-shaped arm 2 and is fixed thereto. The primary inner support frame 51, the secondary inner support frame 52 and the reinforcing member 53 are all lower than the top wall of the V-shaped arm 2. A drainage groove 54 is opened on the top wall of the V-shaped arm 2. A connecting cylinder 4 is fixedly installed at the outer end of the V-shaped arm 2. A connecting shaft 8 is rotatably installed on the inner wall of the connecting cylinder 4. An installation shaft 6 is rotatably installed inside the extended arm 3. In this embodiment of the utility model, the purpose of this arrangement is that the inner support structure 5 can support and strengthen the internal structure of the V-arm 2 during operation. Through the connection and cooperation of the primary inner support frame 51, the secondary inner support frame 52 and the reinforcing member 53, the lower control arm 1 is supported at multiple points, and the V-arm 2 in the lower control arm 1 is constructed into a triangular stable structure, which has an improving effect on the safe and stable operation of the entire vehicle suspension.

[0024] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0025] The working principle of this device is as follows: The lower control arm 1 is mainly constructed by integrally molding the V-shaped arm 2 and the extended arm 3. At the same time, the connecting cylinder 4 installed in the connecting shaft 8 is connected to the vehicle suspension mechanism. Meanwhile, the mounting shafts 6 on the extended arm 3 are all installed and connected to the vehicle suspension mechanism. The inner support structure 5 installed inside the V-shaped arm 2, through the connection and cooperation of the primary inner support frame 51, the secondary inner support frame 52 and the reinforcing member 53, provides a stable support structure inside the V-shaped arm 2. At the same time, as the lower control arm 1 is an important part of the vehicle suspension, the setting of the inner support structure 5 can improve the structural strength of the entire vehicle suspension. Meanwhile, the spring mechanism 7 installed on the lower control arm 1 mainly buffers and absorbs the force generated by the vibration after the car passes over a bumpy road. When the lower control arm 1 is under force, it drives the connecting seat 72 to rotate inside the hinge seat 71. At the same time, the shock absorber 76 and the buffer spring 75 undergo continuous extension and contraction dynamic operation. Simultaneously, the fixed seat 74 and the hinge joint 73 are synchronously connected to the car suspension. When the shock absorber 76 and the buffer spring 75 extend and contract, they will drive the telescopic sleeve 77 and the telescopic protective sleeve 78 to extend and contract synchronously. The telescopic sleeve 77 can provide external protection and structural strength enhancement for the shock absorber 76. The telescopic protective sleeve 78 can provide external protection for the telescopic sleeve 77 and the shock absorber 76, preventing stones and mud from adhering to the piston rod of the shock absorber 76 and causing wear when the car passes over muddy roads.
