Description

Technical Field

[0001] This utility model relates to the field of shock absorber top adhesive technology, specifically a top adhesive for automotive shock absorbers. Background Technology

[0002] In a car's driving system, shock absorbers play a crucial role, effectively absorbing and cushioning various vibrations and impacts from the road surface during vehicle operation, providing a comfortable and smooth driving experience for passengers. The shock absorber top mount, as a key component of the damping system, works closely with the shock absorber to collaboratively perform its damping function. It not only bears the vertical loads during vehicle operation but also copes with complex dynamic forces caused by uneven surfaces, making it an indispensable component for ensuring vehicle stability and comfort.

[0003] However, existing automotive shock absorber top mounts perform poorly when used on ATVs, with the most prominent problem being their short lifespan. ATVs experience significant bumps during operation, subjecting the shock absorber top mount to forces far exceeding normal levels. Since the top mount is primarily composed of rubber, it is highly susceptible to stress tearing under excessive stress, leading to its failure. Once damaged, its shock absorption performance is greatly reduced, resulting in significantly increased vibration and noise during ATV operation, severely impacting the riding experience.

[0004] Furthermore, during prolonged use, the bearings inside the top mount continuously rub against the rubber body. This friction gradually wears down the rubber body, causing a decline in its performance and ultimately leading to top mount failure. Moreover, replacing a damaged top mount is relatively complicated. It requires not only professional repair personnel and tools but may also involve the disassembly and installation of other parts of the ATV, consuming significant time and labor costs. Frequent top mount replacements not only increase operating costs but also cause inconvenience to the normal use of the ATV. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a top mount for automotive shock absorbers, which has the following characteristics:

[0017] Beneficial effects:

[0018] 1. This car shock absorber uses a top rubber mount, which is equipped with a shell, top sleeve, anti-slip structure and reserved deformation structure. The device can be installed at the end of the shock absorber and works with the shock absorber to perform the shock absorption function of ATV. The device has a very long service life, is suitable for use on ATVs, can reduce the amount of maintenance work on ATVs, and has great practicality.

[0019] 2. It is equipped with an anti-slip structure, which can limit the movement of the pressure bearing and prevent the pressure bearing from rotating loosely. The bearing's rotation and friction with the outer shell can easily lead to damage to the outer shell. Limiting its rotation can prevent the outer shell from being cut and can improve the service life of the device.

[0020] 3. It is equipped with a pre-deformation structure. When the top sleeve is subjected to excessive pressure, the deformation convex deforms first. The deformation groove leaves a certain space for deformation, which can prevent the top sleeve from being damaged by stress due to excessive compression. Moreover, the deformation convex bears a large deformation. Even if the deformation convex is damaged due to excessive compression, the disc-shaped base can still cooperate with the outer shell to complete the top adhesive function. The service life of the device is very long. Attached Figure Description

[0026] 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.

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] A top mount for an automotive shock absorber includes a housing 1, a top sleeve 2 on one side of the housing 1, a pressure bearing 3 between the housing 1 and the top sleeve 2, three sets of mounting bolts 4 on the edge of the housing 1, an anti-slip structure 9 inside the housing 1 to prevent the pressure bearing 3 from rotating, and a pre-deformation structure on the top sleeve 2.

[0029] Furthermore, the outer shell 1 includes a covering ring 5, a triangular fixing edge 6, and a perforated cap 7. The outer side of the covering ring 5 is provided with a triangular fixing edge 6, and one end of the covering ring 5 is provided with a perforated cap 7. Three sets of fixing holes 8 are provided on the triangular fixing edge 6, and an anti-slip structure 9 is provided inside the covering ring 5.

[0030] Furthermore, a metal threaded sleeve 10 is provided in the fixing hole 8, and an anti-slip triangular base block 11 is provided on one side of the metal threaded sleeve 10. A triangular groove 12 is provided on the side of the fixing hole 8 away from the covering ring 5. The anti-slip triangular base block 11 is snapped into the triangular groove 12. An installation bolt 4 is threadedly connected to the metal threaded sleeve 10.

[0031] Furthermore, the anti-slip structure 9 includes slots 13 and anti-slip protrusions 14. Three sets of slots 13 are provided on the inner side of the covering ring 5. The outer ring of the pressure bearing 3 is provided with anti-slip protrusions 14 corresponding to the slots 13. The pressure bearing 3 is engaged inside the covering ring 5, with one side of the pressure bearing 3 abutting against the perforated cap 7. The anti-slip protrusions 14 are engaged within the slots 13. The anti-slip protrusions 14, engaged within the slots 13, prevent the pressure bearing 3 from sliding and rotating relative to the outer shell 1. Friction between the pressure bearing 3 and the outer shell 1 generates heat, which could easily cause the pressure bearing 3 to damage the outer shell 1.

[0032] Furthermore, the top sleeve 2 includes a disc-shaped base 15 and a central top protrusion 16. A shock absorber clearance hole is provided in the center of the disc-shaped base 15, and the central top protrusion 16 is located on the outer side of the shock absorber clearance hole. The central top protrusion 16 abuts against the side of the pressure bearing 3 away from the perforated cap 7. A gasket 17 is provided between the central top protrusion 16 and the perforated cap 7. The gasket 17 prevents the central top protrusion 16 from directly contacting the pressure bearing 3, and the gasket 17 increases the contact area, preventing wear on the central top protrusion 16.

[0033] Furthermore, the pre-reserved deformation structure includes a deformation groove 18 and a deformation protrusion 19. The disc-shaped substrate 15 has a deformation groove 18 on the side adjacent to the outer shell 1, and a corresponding deformation protrusion 19 is provided on the side of the disc-shaped substrate 15 away from the deformation groove 18. When subjected to a large impact force, the deformation protrusion 19 deforms, and the deformation groove 18 provides a certain space for deformation, which can prevent stress tearing damage to the material. Moreover, the deformation protrusion 19 has a large deformation, so even if stress tearing damage occurs, the disc-shaped substrate 15 can still cooperate with the outer shell 1 to complete the top adhesive function after the damage.

[0034] Furthermore, the deformation groove 18 is provided with a bolt head relief 20 corresponding to the mounting bolt 4.

[0035] Structural Description:

[0036] Outer shell 1: The external structure of the top adhesive, with a top sleeve 2 connected to one side, a pressure bearing 3 installed inside, and three sets of mounting bolts 4 on the edge, providing protection and a mounting base for the top adhesive as a whole;

[0037] Top sleeve 2: Located on one side of the outer shell 1, it includes a disc-shaped base 15 and a central top protrusion 16. It receives the impact force of the shock absorber through the pressure bearing 3 and is a key component for top rubber buffering and shock absorption.

[0044] Anti-slip structure 9: includes a slot 13 and an anti-slip protrusion 14, which are set inside the housing 1. The two are engaged to restrict the rotation of the pressure bearing 3 and improve the service life of the device.

[0045] Metal threaded sleeve 10: Installed in the fixing hole 8, it is threadedly connected to the mounting bolt 4 to enhance the stability of the connection of the mounting bolt 4 and ensure that the top adhesive is firmly installed;

[0046] Anti-slip triangular base block 11: Set on one side of the metal threaded sleeve 10, it is snapped into the triangular groove 12 to further prevent the mounting bolt 4 from loosening and improve the stability of the top adhesive installation.

[0047] Triangular groove 12: It is formed on the side of the fixing hole 8 away from the covering ring 5, and cooperates with the anti-slip triangular base block 11 to enhance the anti-slip effect when the top adhesive is installed;

[0048] Slot 13: It is opened on the inner side of the covering ring 5 and is engaged with the anti-slip protrusion 14 of the outer ring of the pressure bearing 3. It is a key part of the anti-slip structure 9 and prevents the pressure bearing 3 from rotating.

[0049] Anti-slip protrusion 14: Located on the outer ring of the pressure bearing 3, it engages with the slot 13 to restrict the sliding and rotation of the pressure bearing 3 relative to the outer shell 1, and protect the outer shell 1 from damage;

[0050] The disc-shaped base 15 is a component of the top sleeve 2. It has a shock absorber clearance hole in the center, a deformation groove 18 on the side near the outer shell 1, and a deformation protrusion 19 on the side away from it. It is the main structure of the top sleeve 2.

[0051] The central top protrusion 16 is located on the outside of the shock absorber clearance hole of the disc-shaped base 15, and abuts against the side of the pressure bearing 3 away from the perforated top 7, playing an important role in transmitting impact force.

[0052] Gasket 17: It is placed between the central top protrusion 16 and the perforated top 7 to increase the contact area, prevent the central top protrusion 16 from wearing, and play a role in buffering and protection;

[0053] Deformation groove 18: It is formed on the side of the disc-shaped base 15 near the outer shell 1 to provide deformation space for the deformation protrusion 19 and prevent stress tearing damage to the top sleeve 2;

[0054] Deformation convex 19: Located on the side of the disc-shaped base 15 away from the deformation groove 18, it deforms first when the top sleeve 2 is under pressure, bears a large deformation, and ensures the function of the top adhesive.

[0055] Bolt head clearance 20: It is set in the deformation groove 18 to correspond to the installation of bolt 4, leaving space for the bolt head.

[0056] Working Principle: From the overall installation perspective, the top mount is securely installed on the corresponding part of the ATV using three sets of mounting bolts 4 on the edge of the outer shell 1 and metal threaded sleeves 10 set in the fixing holes 8. The anti-slip triangular base block 11 is engaged in the triangular groove 12, further enhancing the stability of the installation and ensuring that the top mount will not loosen due to vibration or other factors during the operation of the ATV. During shock absorption, when the ATV is bumpy, the shock absorber is subjected to impact force. At this time, the top sleeve 2 of the top mount plays a key role. The top sleeve 2 consists of a disc-shaped base 15 and a central top protrusion 16. The central top protrusion 16 abuts against the side of the pressure bearing 3 away from the perforated top 7. Under the transmission of the pressure bearing 3, the top sleeve 2 bears the impact force transmitted from the shock absorber. The anti-slip structure 9 plays an important auxiliary role. The anti-slip protrusion 14 set on the outer ring of the pressure bearing 3 is engaged in the groove 13 opened on the inner side of the covering ring 5. This design effectively limits the rotation of the pressure bearing 3. If the pressure bearing 3 rotates, it will frequently rub against the outer shell 1, which will not only reduce the service life of the device but may also damage the outer shell 1. The anti-slip structure 9 ensures that the pressure bearing 3 remains stable during force transmission, allowing the entire top adhesive device to operate normally. When encountering a large impact and the top sleeve 2 is subjected to excessive pressure, the reserved deformation structure begins to function. The reserved deformation structure includes a deformation groove 18 and a deformation protrusion 19. The deformation groove 18 on the side of the disc-shaped base 15 adjacent to the outer shell 1 provides deformation space for the deformation protrusion 19 on the side of the disc-shaped base 15 away from the deformation groove 18. When the pressure is too high, the deformation protrusion 19 deforms first. Since the deformation protrusion 19 bears most of the deformation, even if the deformation protrusion 19 is damaged due to excessive compression, the disc-shaped base 15 can still cooperate with the outer shell 1, continuing to transmit and buffer the impact force of the shock absorber through the central top protrusion 16 and the pressure bearing 3, maintaining the basic function of the top adhesive, thereby greatly improving the durability of the top adhesive device. Throughout the entire operation, the gasket 17 is positioned between the central top protrusion 16 and the perforated top seal 7, serving as a buffer and protector, reducing direct friction and wear between components, and further improving the working stability and service life of the top mount device. The tight cooperation of all components enables this automotive shock absorber top mount to efficiently and reliably complete its shock absorption task, providing strong support for the smooth operation of the ATV.
