Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and more specifically, it relates to a reinforced shock absorber mounting bracket. Background Technology

[0002] As a key component of the off-road vehicle suspension system, the performance of the shock absorber's mounting bracket directly affects the vehicle's handling stability, ride comfort, and safety. Shock absorber mounting brackets typically need to withstand complex, multi-directional impact loads transmitted from the wheels, especially under harsh road conditions where the loads are even more severe. Therefore, the mounting brackets must possess sufficient strength, rigidity, and fatigue durability to prevent deformation, cracking, or failure, thus avoiding shock absorber malfunction.

[0003] Traditional shock absorber mounting brackets often employ a single-layer cylindrical structure or a simple plate structure. These structures have the following significant drawbacks:

[0004] Insufficient structural stiffness: When a single-layer cylinder or plate is subjected to complex alternating loads, especially lateral and torsional loads, it is prone to deformation or even fracture, which can cause the damper mounting points to loosen, affecting the damping effect and potentially producing abnormal noise.

[0005] Stress concentration: Significant stress concentration occurs at the installation point (usually fixed by bolts), which can easily lead to fatigue cracks around the bolt holes after long-term use. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a reinforced shock absorber mounting bracket.

[0007] The purpose and effect of this utility model's reinforced shock absorber mounting bracket are achieved through the following specific technical means:

[0008] A reinforced shock absorber mounting bracket includes a mounting sleeve, on one side of which a wire harness bracket is fixedly mounted.

[0009] The mounting sleeve includes

[0010] The inner cylinder has its two ends bent to form a first fixing part;

[0011] The outer cylinder has its two ends bent to form a second fixing part;

[0012] The inner cylinder is located inside the outer cylinder and is arranged in parallel; multiple ribs are evenly arranged between the inner cylinder and the outer cylinder.

[0013] Both the first fixing part and the second fixing part are provided with threaded holes.

[0014] Furthermore, the thickness of the second fixing part is greater than the thickness of the outer cylinder.

[0015] Furthermore, a first cylinder pad is also provided inside the inner cylinder.

[0016] Furthermore, a second gasket is provided between the first fixing part and the second fixing part.

[0017] Furthermore, a U-shaped frame is provided between the two first fixing parts.

[0018] Furthermore, the wire harness bracket includes a fixing part, which is fixedly disposed on the outside of the mounting sleeve; a first plate and a second plate are respectively disposed at both ends of the fixing part in the radial direction; an arc-shaped notch is provided on the first plate; and a through hole is provided on the second plate.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) By adopting a parallel double-layer structure with an inner cylinder and an outer cylinder nested together, and by uniformly setting multiple ribs between the two, a high-strength spatial truss support system is formed, which can effectively resist multi-directional impact loads from the shock absorber, significantly reduce the risk of support deformation, and avoid the shock absorber positioning misalignment or functional failure caused by deformation.

[0021] (2) By bending the inner and outer cylinders at both ends to form a first and second fixed part that are coaxially aligned, and threaded holes are provided through both for bolt fastening, the fastening force of the installation bolts can be borne by the double-layer cylinders, which greatly disperses the concentrated stress around the bolt holes of the traditional single-layer structure, effectively suppresses crack initiation and propagation, and significantly improves the fatigue resistance and long-term reliability of the support.

[0029] Example:

[0030] like Figures 1-3 As shown: A reinforced shock absorber mounting bracket includes a mounting sleeve 1, which comprises an inner cylinder 11 and an outer cylinder 12. The inner cylinder 11 is coaxially fitted inside the outer cylinder 12, and the two are arranged in parallel and spaced apart to form a double-layer cylinder load-bearing structure. Through the coordinated load-bearing of the inner and outer cylinders, the bracket's ability to resist bending and torsional loads is significantly improved, avoiding shock absorber positioning misalignment caused by deformation of a single-layer cylinder.

[0031] The inner cylinder 11 is bent at both ends to form a first fixing part 1101; the outer cylinder 12 is bent at both ends to form a second fixing part 1201; the two are coaxially aligned, and the threaded hole 2 passes through both the first fixing part 1101 and the second fixing part 1201. The double-layer fixing parts share the bolt preload, disperse the stress concentration of traditional single-point installation, and extend fatigue life; the coaxial design ensures that the bolt is subjected to vertical force, preventing eccentric wear.

[0032] Multiple ribs 13 are uniformly welded between the inner cylinder 11 and the outer cylinder 12, and are equidistantly distributed along the circumference. The ribs form a radial support network, connecting the two-layer cylinders into an integral rigid frame, suppressing vibration deformation; multi-directional loads are uniformly transferred to the inner and outer cylinders through the ribs, improving impact resistance.

[0033] A wire harness bracket 4 is fixedly installed on one side of the mounting sleeve 1; the wire harness bracket 4 includes a fixing part 41, which is fixedly installed on the outside of the mounting sleeve 1; a first plate 42 and a second plate 43 are respectively provided at both ends of the fixing part 41 in the radial direction; by adopting integrated welding, additional assembly is avoided, ensuring that the wire harness bracket and the shock absorber bracket are subjected to force synchronously; the double plate design provides multi-directional wire harness fixing positions to adapt to complex wiring requirements.

[0034] The first plate 42 is provided with an arc-shaped notch 45, which provides a quick snap-in fixation for the wire harness, preventing it from falling off and reducing shock. The second plate 43 is provided with a through hole 44, which supports secondary fastening with cable ties, providing double protection for the stability of the wire harness and preventing it from loosening and wearing off during driving.

[0035] The thickness of the second fixing part 1201 is greater than the thickness of the outer cylinder 12. Specifically, the thickness of the second fixing part 1201 of the outer cylinder 12 is increased to 1.5-2 times that of the outer cylinder 12. This localized thickening enhances the crush resistance around the bolt holes, prevents deformation under high preload, and improves installation reliability.

[0036] The inner cylinder 11 is also equipped with a first cylinder pad 33. This pad isolates the shock absorber rod from the metal cylinder, buffering high-frequency vibration and noise; it also seals and prevents dust, protecting the surface of the rod.

[0037] A second shim 31 is provided between the first fixing part 1101 and the second fixing part 1201. This compensates for machining tolerances on the mounting surface, ensures uniform distribution of bolt preload, suppresses fretting wear, and prevents bolt loosening and failure.

[0038] A U-shaped frame 32 is provided between the two first fixing parts 1101. It provides lateral support to both ends of the inner cylinder, improves the torsional stiffness of the double-layer sleeve, suppresses resonance deformation, and extends the overall structural life.

[0039] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
