Description

Technical Field

[0001] This utility model belongs to the field of pure rubber suspension technology, specifically, it relates to a pure rubber suspension structure based on riveting. Background Technology

[0002] A suspension mount is an elastic support device used to isolate and dampen mechanical vibrations, typically installed between the powertrain (such as an engine or electric motor) and the vehicle body or chassis. Its core function is to absorb vibration energy through the deformation of elastic elements (such as rubber, hydraulic, or pure rubber structures), effectively reducing the transmission of vibration and noise to the vehicle body. Modern suspension mounts employ multi-directional stiffness designs to simultaneously handle vibration excitations of different frequencies, while also meeting support, limiting, and vibration isolation requirements.

[0003] Pure adhesive suspension is a novel flexible connection technology that uses high-performance elastic adhesives to replace traditional metal suspensions, aiming to provide excellent shock absorption and vibration isolation effects. It achieves effective absorption of vibration and impact through the viscoelastic properties of the adhesive, significantly reducing noise and vibration transmission.

[0004] Currently, the pure rubber suspension widely used in the automotive industry generally adopts a composite process structure of metal skeleton and rubber vulcanization. It requires a complex side-pressure assembly process to combine the metal insert and rubber material. This traditional manufacturing method not only increases the cost of mold development, but also makes the production process complicated due to the composite of multiple materials, resulting in high unit production costs and pushing up the procurement costs of OEMs, which has certain limitations. Utility Model Content

[0005] To address the technical problem that current pure rubber suspension systems are assembled by side pressing with a metal frame, which is complex and leads to increased production costs, this utility model provides a pure rubber suspension structure based on riveting.

[0006] The objective of this utility model can be achieved through the following technical solutions: A pure rubber suspension structure based on riveting includes an aluminum bracket, a rubber body, and an aluminum support arm that are assembled with each other; the aluminum support arm is inserted into the rubber body; the rubber body is inserted into the aluminum bracket; a rubber inner skeleton is embedded inside the rubber body; a sheet metal lower support is provided at the lower part inside the rubber body, and the rubber body, the rubber inner skeleton, and the sheet metal lower support are vulcanized as a whole.

[0007] Furthermore, the aluminum bracket has a first groove; the upper wall of the first groove has an M-shaped structure; both ends of the sheet metal lower support have bent portions; the bent portions at both ends of the sheet metal lower support are engaged with the two sides of the first groove on the aluminum bracket.

[0008] Furthermore, the aluminum bracket has a cutout at the position corresponding to the upper part of the first groove; the front and rear sides of the aluminum bracket have two triangular grooves and one trapezoidal groove with openings at the position corresponding to the upper part of the first groove; three hooks are equidistantly arranged on both sides of the sheet metal lower support; the rubber body is inserted into the first groove, so that the hooks are bent and extended into the triangular groove and trapezoidal groove to form a snap-fit ​​riveting structure.

[0009] Furthermore, a second groove is formed on the rubber body; a groove is formed on the bottom wall of the second groove; an integral connecting part is provided on the left side of the aluminum support arm; a protrusion is provided on the end face of the connecting part; the protrusion on the end face of the connecting part is inserted into the groove at the bottom of the second groove on the rubber body.

[0010] Furthermore, the rubber body is provided with a plurality of first protrusions and second protrusions at equal intervals; the first protrusions are in contact with the bottom wall of the first groove; and the second protrusions are in contact with the M-shaped groove wall at the top of the first groove.

[0011] Furthermore, multiple third protrusions are equidistantly arranged on the inner wall of the second groove; the third protrusions are in contact with the outer surface of the connecting part.

[0012] Furthermore, the rubber inner skeleton is embedded in the periphery of the second groove.

[0013] Furthermore, the rubber inner skeleton has multiple first circular holes; the sheet metal lower support has multiple second circular holes.

[0014] The beneficial effects of this utility model are: 1. This utility model assembles the aluminum bracket, rubber body, and aluminum support arm into one unit by riveting. It further enhances the stability of the riveting by utilizing the cooperation of structures such as hooks, triangular grooves and trapezoidal grooves, protrusions and grooves, and bending parts and the two sides of the first groove. The process is simple, simplifies the assembly process, reduces production costs, and improves utilization. It solves the technical problem that the current pure rubber suspension is assembled by side pressure of metal frame, which is complicated and leads to increased production costs.

[0015] 2. The sheet metal lower support in this utility model adopts a sheet metal structure. Compared with a metal frame, sheet metal is lighter and cheaper, making it more suitable for the production of pure rubber suspension. In addition, the sheet metal lower support is wrapped inside the rubber body, avoiding direct collision with metal, reducing metal impact noise, and increasing practicality.

[0016] 3. This utility model has multiple first, second, and third protrusions on the rubber body. The protrusions fit tightly with the relevant structures, increasing the contact area and improving the sealing performance through deformation compensation, effectively preventing the structure from falling off. In addition, the multi-directionally distributed protrusions form a three-dimensional support network, which disperses stress when subjected to radial and axial loads, avoiding local deformation. Furthermore, the special arrangement of the protrusions can guide the transmission path of vibration waves. Combined with the damping characteristics of the rubber material itself, it can achieve a wide-band vibration suppression and damping effect, thereby improving the vibration reduction effect.

[0017] 4. This utility model optimizes the local stiffness of the rubber inner skeleton and the sheet metal lower support by opening multiple first and second round holes on the rubber inner skeleton and the sheet metal lower support respectively through the distribution of holes. This reduces the overall weight while ensuring structural strength and enhances the deformation capacity in a specific direction. In addition, the round holes can be filled with cured rubber, and the mechanical interlocking improves the peel strength of the adhesive interface. Attached Figure Description
