Description

Technical Field

[0001] The utility model belongs to the technical field of automobile accessories, and in particular relates to an impact-resistant automobile swing arm bushing. Background Art

[0002] When a car is driving, it will vibrate due to the uneven road surface. Part of the impact force generated by the vibration is absorbed by the tires, but another part needs to be absorbed by the suspension device between the tires and the car body. The bushing structure is more commonly used in the suspension system. The bushing structure can attenuate and cushion the impact and vibration from the ground, so that the car body has better handling stability and ride comfort.

[0003] According to the search, most existing bushing bodies are composed of two layers of metal skeletons and a rubber layer, with the rubber layer placed between the two layers of metal skeletons. The bushing body itself has a certain impact resistance effect, which can effectively reduce the spread of vibration and improve driving comfort. At the same time, it can support and protect automobile parts, which helps to improve the stability, safety and durability of the automobile.

[0004] However, in reality, since the automobile swing arm bushing will be subjected to a greater impact force when the automobile vibrates, the two inner and outer metal skeleton layers will be squeezed toward the middle rubber layer. When the rubber layer is squeezed for a long time, it will eventually crack, causing damage to the bushing and affecting the safety of vehicle driving. In addition, since the bushing is directly installed in the automobile swing arm, after long-term use, the outermost metal skeleton layer will wear and tear, affecting the service life of the bushing.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: it includes a bushing body 1, the outer part of the bushing body 1 is detachably covered with a protective shell 3, four groups of buffer pads 4 are fixed around the inner wall of the protective shell 3, four groups of positioning grooves 5 are opened on the inner wall of the protective shell 3, and the positioning grooves 5 are located between two adjacent groups of buffer pads 4, and a fixing column 2 fixedly connected to the outer wall of the bushing body 1 is slidably arranged in the positioning groove 5, two fixing grooves 9 are symmetrically opened on the innermost inner wall of the positioning groove 5, and a fixing component is arranged in the fixing groove 9, and covering components for protecting the buffer pads 4 are arranged at both ends of the bushing body 1.

[0007] It should be noted in the scheme that the fixing component includes a fixing slider 8 slidably arranged inside the fixing groove 9, a rectangular groove corresponding to the fixing groove 9 is opened on the side wall of the fixing column 2, one end of the fixing slider 8 is inserted into the rectangular groove, and a spring 10 is fixed between the other end of the fixing slider 8 and the innermost inner wall of the fixing groove 9.

[0008] It is further worth explaining that the covering component includes a protective cover plate 6 which is annularly fitted to the end face of the protective shell 3, the inner wall of the protective cover plate 6 is tightly fitted to the outer wall of the bushing body 1, and a plurality of fixing rods 7 are arranged around and penetrate the top face of the protective cover plate 6. A plug-in hole 11 which is adapted to the fixing rod 7 is provided on the end face of the protective shell 3, and the plug-in hole 11 is connected to the inside of the fixing groove 9.

[0009] It is further worth noting that the end of the fixed slider 8 away from the rectangular groove is in a hypotenuse shape, and one end of the fixed rod 7 penetrates into the fixed groove 9 and abuts against the hypotenuse of the fixed slider 8.

[0010] Compared with the prior art, the impact-resistant automobile swing arm bushing provided by the utility model has at least the following beneficial effects:

[0011] (1) The utility model provides a protective shell and a buffer pad. When used in practice, the protective shell can protect the bushing body and can replace the bushing body in contact with the outside, thereby protecting the outermost metal skeleton layer of the bushing body from wear and tear, thereby increasing the service life of the bushing body. The buffer pad on the inner wall of the protective shell can play a buffering role. When the bushing body is subjected to an impact force, the buffer pad will be squeezed first, thereby achieving a buffering and shock-absorbing effect.

[0012] (2) The utility model can protect the cushion by setting the covering component, and prevent the cushion from being affected by dust and moisture that enter the cushion during the driving of the car, causing the cushion to get damp, causing the glue inside the cushion to soften and become gelatinized, and ultimately causing the cushion to be unable to play a normal cushioning and shock-absorbing effect. By setting the fixing component, the protective cover can be further fixed to the protective shell after the fixing rod is inserted into the fixing groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 and Figure 2 As shown, the utility model provides an impact-resistant automobile swing arm bushing, comprising a bushing body 1;

[0022] According to the search, the existing bushing body 1 is mostly composed of two layers of metal skeleton and rubber layer, and the rubber layer is placed between the two layers of metal skeleton. The setting of the bushing body 1 can effectively reduce the propagation of vibration and improve driving comfort. At the same time, it can support and protect the automobile parts, which helps to improve the stability, safety and durability of the automobile.

[0023] However, in reality, since the automobile swing arm bushing will be subjected to a greater impact force when the automobile vibrates, the two inner and outer metal skeleton layers will be squeezed toward the middle rubber layer. When the rubber layer is squeezed for a long time, it will eventually crack, causing damage to the bushing and affecting the safety of vehicle driving. In addition, since the bushing is directly installed in the automobile swing arm, after long-term use, the outermost metal skeleton layer will wear and tear, affecting the service life of the bushing.

[0024] To solve the above problems, refer to Figures 1 to 3 As shown, it is worth noting that the outer detachable cover of the bushing body 1 is provided with a protective shell 3, and four groups of buffer pads 4 are fixed around the inner wall of the protective shell 3;

[0025] By setting the protective shell 3 and the buffer pad 4, the protective shell 3 is sleeved on the bushing body 1 through the fixing column 2, and then the bushing is installed as a whole on the automobile swing arm. In actual use, the protective shell 3 can protect the bushing body 1 and can replace the bushing body 1 to contact the outside, thereby protecting the outermost metal skeleton layer of the bushing body 1 from wear and tear, thereby improving the service life of the bushing body 1. The buffer pad 4 on the inner wall of the protective shell 3 can play a buffering role. When the bushing body 1 is subjected to impact force, the buffer pad 4 will be squeezed first, thereby playing a buffering and shock-absorbing effect.

[0026] Further, refer to Figures 2 to 4 As shown, it is worth noting that four groups of positioning grooves 5 are opened on the inner wall of the protective shell 3, and the positioning grooves 5 are located between two adjacent groups of the buffer pads 4, and the fixing columns 2 fixedly connected to the outer wall of the bushing body 1 are slidably arranged in the positioning grooves 5;

[0027] By setting the positioning groove 5 and the fixing column 2, the protective shell 3 is rotated to adjust the positioning groove 5 to a position corresponding to the fixing column 2. At this time, the protective shell 3 can be sleeved on the bushing body 1 through the cooperation between the positioning groove 5 and the fixing column 2.

[0028] Further, refer to Figure 5 and Figure 6 As shown, it is worth noting that two fixing grooves 9 are symmetrically provided on the innermost inner wall of the positioning groove 5, and fixing components are provided in the fixing grooves 9, and covering components for protecting the buffer pad 4 are provided at both ends of the bushing body 1;

[0029] The fixing component includes a fixing slider 8 slidably arranged inside the fixing groove 9, a rectangular groove corresponding to the fixing groove 9 is opened on the side wall of the fixing column 2, one end of the fixing slider 8 penetrates into the rectangular groove, and a spring 10 is fixed between the other end of the fixing slider 8 and the innermost inner wall of the fixing groove 9;

[0030] The covering component includes a protective cover plate 6 in an annular shape and attached to the end surface of the protective shell 3. The inner wall of the protective cover plate 6 is tightly attached to the outer wall of the bushing body 1. A plurality of fixing rods 7 are circumferentially passed through the top surface of the protective cover plate 6. A plug-in hole 11 adapted to the fixing rod 7 is provided on the end surface of the protective shell 3. The plug-in hole 11 is connected to the inside of the fixing groove 9.

[0031] The end of the fixed slider 8 away from the rectangular groove is in a hypotenuse shape, and one end of the fixed rod 7 penetrates into the fixed groove 9 and abuts against the hypotenuse of the fixed slider 8;

[0032] When in use, first place the protective cover 6 above the protective shell 3 and adjust the protective cover 6 to a position corresponding to the insertion hole 11, then insert the fixing rod 7 through the insertion hole 11 and insert it into the fixing groove 9, and after the fixing rod 7 abuts against the hypotenuse of the fixing slide 8, the fixing rod 7 continues to move downward, at this time, the fixing rod 7 can drive the fixing slide 8 to move toward the rectangular groove on the side wall of the fixing column 2, and after the fixing rod 7 is completely inserted into the fixing slide 8, the protective cover 6 can be fixed above the protective shell 3 by the fixing slide 8. When the protective cover 6 needs to be removed, it is only necessary to pull the fixing rod 7 out of the protective cover 6. At this time, the fixing slide 8 will rebound to its original position under the rebound force of the spring 10, and the fixing of the protective cover 6 can be cancelled;

[0033] By setting the covering component, the buffer pad 4 can be protected to prevent the buffer pad 4 from being affected by dust and moisture entering during the driving of the car, causing the buffer pad 4 to get damp, causing the glue inside to soften and produce gelatinization, and ultimately causing the buffer pad 4 to be unable to play a normal buffering and shock-absorbing effect. By setting the fixing component, the protective cover plate 6 can be further fixed on the protective shell 3 after the fixing rod 7 is inserted into the fixing groove 9.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
