Description

Technical Field

[0001] This utility model relates to the field of automotive shock absorber components technology, specifically to an auxiliary module rubber suspension. Background Technology

[0002] In the automotive industry, rubber mounts in auxiliary modules are components used for vibration damping and isolation, primarily applied in automotive systems where reduced vibration transmission is required. The function of rubber mounts is to absorb and isolate vibrations generated by the powertrain (such as engines and auxiliary components) through their elastic properties, preventing these vibrations from being transmitted to other structural parts, thereby improving equipment stability, extending service life, and reducing noise.

[0003] Existing automotive auxiliary module rubber suspension structures are mainly hydraulic suspension structures. Although this type of auxiliary module rubber suspension can dampen the powertrain and corresponding connecting parts in the vehicle, its complex structure leads to high overall manufacturing costs. Furthermore, when encountering sudden stress that causes the rubber suspension to displace beyond the preset displacement, this type of auxiliary module rubber suspension will fail, resulting in excessive displacement of the powertrain and collision damage to other mechanisms. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to provide an auxiliary module rubber suspension that is simple in structure, easy to manufacture, and can prevent the rubber suspension from failing due to excessive compression damage when encountering sudden stress that causes the displacement to exceed the preset displacement. This is achieved by the wrist support making rigid contact with the upper limit end cap and the lower limit end cap.

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes an auxiliary machine module rubber suspension, including shock-absorbing rubber, an upper limit end cap installed at the top of the shock-absorbing rubber, a lower limit end cap installed at the bottom of the shock-absorbing rubber, a connecting bolt connected to the middle of the upper limit end cap and the lower limit end cap, and a wrist support frame connected to one end of the shock-absorbing rubber by a fixing nut, and a limit protrusion installed around the fixing nut.

[0008] Furthermore, a sign is also installed on one side of the top of the shock-absorbing rubber.

[0009] By adopting the above technical solution, the label records the model information of the rubber suspension, so as to facilitate the convenient installation and use of the rubber suspension.

[0010] Furthermore, both the upper limit end cap and the lower limit end cap are welded to the corresponding connecting bolts, and the connecting bolts penetrate the corresponding upper limit end cap and the lower limit end cap.

[0011] By adopting the above technical solution, the welding and fixing method makes the installation of the connecting bolts more stable, while the connecting bolts facilitate the connection of the rubber suspension to the transmission components and other components on the vehicle.

[0012] Furthermore, the fixing nut is threadedly connected to the connecting bolt, and the limiting protrusion is formed on the fixing nut.

[0013] By adopting the above technical solution, the fixing nut can achieve reliable installation and positioning of the wrist support frame.

[0014] Furthermore, the wrist support frame, the fixing nut, and the limiting protrusion are all located inside the shock-absorbing rubber.

[0015] By adopting the above technical solution, the wrist support frame, the fixing nut, and the limiting protrusion are all located inside the shock-absorbing rubber, which can ensure the integrity of the rubber suspension structure.

[0016] Furthermore, both the upper limit end cap and the lower limit end cap are bonded to the shock-absorbing rubber, which has a cylindrical structure.

[0017] By adopting the above technical solution, the shock-absorbing rubber is the main shock-absorbing structure of the rubber suspension, so as to buffer and dampen the power components and other components of the vehicle.

[0018] Furthermore, both the upper limit end cap and the lower limit end cap are disc-shaped structures, and both are made of stainless steel.

[0019] By adopting the above technical solution, the stainless steel material makes the upper limit end cap and the lower limit end cap have better structural strength and will not be easily deformed or damaged.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, this utility model has the following advantages:

[0022] To address the issue that existing automotive auxiliary module rubber mount structures are primarily hydraulic mounts, which, while effective at damping the powertrain and connecting components, suffer from high manufacturing costs due to their complexity, and fail when subjected to sudden stress causing displacement exceeding pre-set limits, potentially leading to powertrain collisions and damage, this invention employs an upper limit end cap, a lower limit end cap, damping rubber, connecting bolts, and a wrist rest frame. With this main structure, the overall structure of the automotive auxiliary module rubber suspension is greatly simplified, facilitating rapid manufacturing and significantly reducing manufacturing costs. Simultaneously, when encountering sudden stress causing displacement exceeding a preset range, the rigid contact between the wrist support frame and the upper and lower limit end caps prevents damage to the damping rubber due to excessive compression. Furthermore, stiffness compensation effectively delays and stops vertical vibrations, resulting in smoother stiffness in the linear section. Additionally, limiting the powertrain's displacement to a certain range prevents excessive powertrain displacement from colliding and damaging other mechanisms. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] like Figures 1-2As shown, an auxiliary module rubber suspension in this embodiment includes a shock-absorbing rubber 4. An upper limit end cap 2 is installed at the top of the shock-absorbing rubber 4, and a lower limit end cap 5 is installed at the bottom of the shock-absorbing rubber 4. A connecting bolt 1 is connected to the middle of both the upper limit end cap 2 and the lower limit end cap 5. The connecting bolt 1 is located at one end of the shock-absorbing rubber 4 and is connected to a wrist support frame 3 by a fixing nut 7. A limiting protrusion 6 is installed around the fixing nut 7. The fixing nut 7 can reliably limit the installation of the wrist support frame 3. The shock-absorbing rubber 4 is the main shock-absorbing structure of this rubber suspension to buffer and dampen the vehicle's power components and other components. The wrist support frame 3, the fixing nut 7, and the limiting protrusion 6 are all located inside the shock-absorbing rubber 4, which can ensure the integrity of the rubber suspension structure.

[0029] like Figures 1-2 As shown in this embodiment, a label 8 is also installed on one side of the top of the shock-absorbing rubber 4. The label 8 records the model information of the rubber suspension to facilitate the convenient installation and use of the rubber suspension.

[0030] like Figures 1-2 As shown, in this embodiment, both the upper limit end cap 2 and the lower limit end cap 5 are welded to the corresponding connecting bolts 1. The connecting bolts 1 pass through the corresponding upper limit end cap 2 and lower limit end cap 5. The welding fixation method makes the installation of the connecting bolts 1 more stable. The connecting bolts 1 facilitate the connection of the rubber suspension to the transmission components and other components on the vehicle. The fixing nut 7 is threadedly connected to the connecting bolt 1. The limiting protrusion 6 is formed on the fixing nut 7. The wrist support frame 3, the fixing nut 7, and the limiting protrusion 6 are all located inside the shock-absorbing rubber 4. Both the upper limit end cap 2 and the lower limit end cap 5 are bonded to the shock-absorbing rubber 4. The shock-absorbing rubber 4 has a cylindrical structure. Both the upper limit end cap 2 and the lower limit end cap 5 have a disc-shaped structure. Both the upper limit end cap 2 and the lower limit end cap 5 are made of stainless steel. The stainless steel material makes the structure of the upper limit end cap 2 and the lower limit end cap 5 stronger and less prone to deformation and damage.

[0031] The specific implementation process of this embodiment is as follows: In use, the rubber suspension is first installed between the vehicle powertrain and other connecting components using the connecting bolt 1. Then the rubber suspension can be put into use. Since the main structure of this type of automotive auxiliary module rubber suspension is based on the upper limit end cap 2, lower limit end cap 5, shock-absorbing rubber 4, connecting bolt 1, and wrist support frame 3, the overall structure of this type of automotive auxiliary module rubber suspension is greatly simplified, making it easy to manufacture quickly and significantly reducing the manufacturing cost of the automotive auxiliary module rubber suspension. At the same time, when encountering sudden stress that causes the displacement to exceed the preset displacement, the wrist support frame 3 can rigidly contact the upper limit end cap 2 and the lower limit end cap 5, which can prevent the shock-absorbing rubber 4 from being damaged due to excessive compression. Moreover, the stiffness compensation has a good delaying and stopping effect on the vertical vibration of the vehicle, making the stiffness in the linear section smoother. In addition, limiting the powertrain to a certain displacement can prevent the powertrain from colliding and being damaged by other mechanisms due to excessive displacement.

[0032] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
