Description

Technical Field

[0001] This utility model belongs to the field of shock absorber top adhesive technology, specifically, it relates to a shock absorber top adhesive assembly. Background Technology

[0002] The shock absorber top mount is a core buffer component in the automotive suspension system. Made of rubber, it is located between the shock absorber spring and the vehicle body, bearing more than 1 / 4 of the dynamic impact force of the vehicle body. When passing over speed bumps or potholes, it absorbs vibrations through viscoelastic deformation, preventing rigid collisions between metal parts (the impact sound without the top mount is a "clang," while with the top mount it is a "thump"), significantly improving driving comfort, blocking the transmission of noise generated by tire-road friction into the cabin, improving ride quietness, absorbing road impact energy, and preventing damage to shock absorber oil seals, wheel hubs, etc., from direct impacts.

[0003] Chinese utility model patent CN215928205U discloses a shock absorber top rubber assembly. The frame includes a support frame protruding from its center and a mounting frame surrounding the support frame. The end of the support frame is recessed to form a mounting groove. A basin frame is provided on the back of the mounting groove. The bottom of the mounting groove and the bottom of the basin frame are provided with interconnected through holes. There are two rubber pads, which are installed in the mounting groove and the basin frame respectively. The bottom surface of the rubber pad is provided with a deformation groove and a through hole. The deformation groove, the bottom of the mounting groove, and the bottom of the basin frame form a cavity. The through hole communicates with the cavity and the through hole. A buffer sleeve is set in the through hole and passes through the cavity and the through hole. The length of the buffer sleeve is less than the distance between the top surfaces of the two rubber pads after assembly.

[0004] Although the top mount can be installed with rubber pads and buffer sleeves, eliminating the need for bonding rubber to the frame, the springs of the shock absorber need to be fixed when replacing the top mount assembly to prevent them from springing outwards during disassembly. However, this method is extremely troublesome, making the replacement of the top mount very inconvenient. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problem mentioned in the background art that although the top rubber can be installed with rubber pads and buffer sleeves without the need for bonding rubber to the frame, the spring of the shock absorber needs to be fixed when replacing the top rubber assembly to prevent it from springing outward during disassembly, which is extremely cumbersome and makes replacing the top rubber very inconvenient, the present invention adopts the following technical solution.

[0007] A shock absorber top rubber assembly includes a connecting frame, a rubber pad is bonded to the outside of the connecting frame, a plurality of protruding plates are fixedly connected to the outer wall of the rubber pad, the connecting frame is detachably connected to the shock absorber, the rubber pad is detachably connected to the connecting frame, and when the rubber pad is removed, the connecting frame limits the spring of the shock absorber.

[0008] Preferably, the shock absorber screw passes through the center of the connecting frame and the rubber pad, the upper end of the connecting frame is provided with a concave part, the shock absorber screw passes through the center of the concave part, and the shock absorber screw is threaded to the outer wall of the concave part of the connecting frame with a second hexagonal nut.

[0009] Preferably, the end of the shock absorber screw is inserted into the recess of the rubber pad, and the end of the shock absorber screw is threaded with a first hexagonal nut.

[0010] Preferably, a rotating bearing is rotatably connected to the bottom of the connecting frame.

[0011] Preferably, the bottom of the first hexagonal nut has the same curvature as the concave part of the rubber pad.

[0012] Preferably, the shock absorber screw passes through the concave part of the connecting frame and is threadedly connected to a third hexagonal nut. The bottom of the third hexagonal nut is provided with an arc that fits the concave part of the connecting frame. The upper end of the third hexagonal nut is fixedly connected to a threaded post. The threaded post passes through the rubber pad and is threadedly connected to the first hexagonal nut.

[0013] Preferably, the bottom of the third hexagonal nut is fixedly connected to an arc-shaped base plate, which fits against the inner wall of the concave part of the connecting frame. The threaded post passes through the rubber pad and is threadedly connected to a fourth hexagonal nut. The bottom of the fourth hexagonal nut is fixedly connected to an arc-shaped pressure plate, which fits against the concave part of the rubber pad.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The second hex nut connects the frame to the shock absorber, preventing the shock absorber spring from extending outwards and rebounding when replacing the rubber pads, thus making the replacement of the rubber pads more convenient.

[0015] 2. The rubber pad is fixed to the connecting frame by the first hexagonal nut. When the rubber pad needs to be replaced, simply remove the first hexagonal nut and tear the rubber pad off the outside of the connecting frame to complete the removal of the rubber pad. When installing the rubber pad, put the rubber pad on the outside of the connecting frame and thread the first hexagonal nut to the end of the shock absorber screw to fix the rubber pad.

[0016] 3. The rotating bearing reduces the steering resistance of the car. The rotating bearing and the rubber pad share the cushioning task, and the rotating bearing disperses the lateral stress during steering.

[0017] 4. The arc at the bottom of the first hexagonal nut can completely fit with the concave part of the rubber pad, thus making the fixing effect of the rubber pad better.

[0018] 5. By integrating the threaded post and the third hexagonal nut, the rubber pad can be clamped more tightly after the first hexagonal nut is tightened, in conjunction with the third hexagonal nut.

[0019] 6. The curved pressure plate and curved base plate can increase the contact area between the fourth and third hexagonal nuts and the concave part, resulting in a better fixing effect. Attached Figure Description

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0025] Example 1 like Figure 1 as well as Figure 4 The diagram shown is a schematic diagram of a preferred embodiment of the present invention for a shock absorber top mount assembly. The shock absorber top mount assembly of this embodiment includes a connecting frame 105, a rubber pad 100 is bonded to the outside of the connecting frame 105, a shock absorber screw 104 passes through the center of the connecting frame 105 and the rubber pad 100, and a plurality of protruding plates 101 are fixedly connected to the outer wall of the rubber pad 100. In this embodiment, the rubber pad 100 can reduce the friction between the shock absorber and the vehicle chassis, and the shock absorber is connected to the vehicle chassis by bolts passing through the protruding plates 101.

[0026] like Figure 3 as well as Figure 4 As shown, this is a schematic diagram of the second hexagonal nut structure in this embodiment. The upper end of the connecting frame 105 is provided with a concave portion. The shock absorber screw 104 passes through the center of the concave portion. The shock absorber screw 104 is threaded to the outer wall of the concave portion of the connecting frame 105 with a second hexagonal nut 106. In this embodiment, the connecting frame 105 and the shock absorber can be connected by the second hexagonal nut 106, so that when the rubber pad 100 is replaced, the spring of the shock absorber will not extend outward and rebound, thereby making the replacement of the rubber pad 100 more convenient.

[0027] like Figure 4As shown, the rubber pad 100 also has a concave portion at the top center. The end of the shock absorber screw 104 is inserted into the concave portion of the rubber pad 100. The end of the shock absorber screw 104 is threadedly connected to the first hexagonal nut 102. In this embodiment, the rubber pad 100 is fixed to the connecting frame 105 by the first hexagonal nut 102. When the rubber pad 100 needs to be replaced, it is only necessary to remove the first hexagonal nut 102 and tear the rubber pad 100 off the outside of the connecting frame 105 to complete the disassembly of the rubber pad 100. When installing the rubber pad 100, the rubber pad 100 is placed on the outside of the connecting frame 105, and the first hexagonal nut 102 is threadedly connected to the end of the shock absorber screw 104, thereby fixing the rubber pad 100.

[0028] like Figure 2 As shown, it is a schematic diagram of the connecting frame structure in this embodiment. The bottom of the connecting frame 105 is rotatably connected to a rotating bearing 103. In this embodiment, the steering resistance of the car is reduced by the rotating bearing 103. The rotating bearing 103 and the rubber pad 100 jointly undertake the buffering task. The rotating bearing 103 disperses the lateral stress during steering.

[0029] Example 2 like Figure 5 As shown, this is another preferred embodiment of the present invention. The difference between the top adhesive assembly in this embodiment and that in embodiment 1 is that the bottom of the first hexagonal nut 102 is provided with the same curvature as the concave part of the rubber pad 100. In this embodiment, the curvature provided at the bottom of the first hexagonal nut 102 can completely fit with the concave part of the rubber pad 100, thereby making the fixing effect of the rubber pad 100 better.

[0030] like Figure 5 As shown, the shock absorber screw 104 passes through the concave part of the connecting frame 105 and is threadedly connected to a third hexagonal nut 200. The bottom of the third hexagonal nut 200 is provided with an arc that fits the concave part of the connecting frame 105. The upper end of the third hexagonal nut 200 is fixedly connected to a threaded post 201. The threaded post 201 passes through the rubber pad 100 and is threadedly connected to the first hexagonal nut 102. In this embodiment, by the integral setting of the threaded post 201 and the third hexagonal nut 200, the rubber pad 100 can be clamped more tightly after the first hexagonal nut 102 is tightened.

[0031] Example 3 like Figure 6As shown, this is another preferred embodiment of the present invention. The difference between the top adhesive assembly in this embodiment and that in embodiment 2 is that the bottom of the third hexagonal nut 200 is fixedly connected to an arc-shaped base plate 202, which fits against the inner wall of the concave part of the connecting frame 105. The threaded post 201 passes through the rubber pad 100 and is threadedly connected to the fourth hexagonal nut 203. The bottom of the fourth hexagonal nut 203 is fixedly connected to an arc-shaped pressure plate 204, which fits against the concave part of the rubber pad 100. In this embodiment, the arc-shaped pressure plate 204 and the arc-shaped base plate 202 can increase the contact area between the fourth hexagonal nut 203 and the third hexagonal nut 200 and the concave part, thus improving the fixing effect.
