[0003] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art:

[0004] After prolonged use, existing automotive chassis bushings may crack or break due to repeated twisting of the internal rubber sleeve. In such cases, workers need to remove the damaged automotive chassis bushings for inspection. However, the shattered internal rubber sleeves are difficult to remove, which reduces the efficiency of automotive chassis bushing inspection.

[0005] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0006] The purpose of this invention is to provide a quick-change bushing for an automotive chassis, thereby solving the problems mentioned in the background section.

[0007] By adopting the above technical solution, the problem of reduced maintenance efficiency of the automotive chassis bushing is solved, which is caused by the inner rubber sleeve sticking to the inner wall of the main body of the chassis bushing after damage and being inconvenient to remove.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] A quick-change bushing for an automobile chassis includes an automobile chassis bushing body, an inner rubber sleeve disposed inside the automobile chassis bushing body, and an inner shaft fixedly installed inside the inner rubber sleeve. The top of the automobile chassis bushing body has a groove, and the front and rear ends of the inner wall of the automobile chassis bushing body have sliding grooves, with the top of the sliding grooves communicating with the grooves. A fixing rod fixedly connected to the inner rubber sleeve is slidably installed inside the sliding grooves, and there are two sets of fixing rods at each end. A reinforcing plate is fixedly connected between each set of fixing rods.

[0010] Preferably, a sealing plate is movably installed on the top of the groove, and a stop block is fixedly installed at the front and rear ends of the bottom of the sealing plate, with the stop block located at the top of the fixing rod.

[0011] Preferably, fixing blocks are fixedly installed on both sides of the bottom of the sealing plate, and limiting plates extending into the limiting groove of the fixing blocks are fixedly installed on both sides of the inner wall of the groove.

[0012] Preferably, a spring is fixedly installed inside the fixing block, a first limiting hole is opened inside the limiting plate, and second limiting holes are opened on both sides of the sealing plate. A limiting block extending into the first limiting hole and the second limiting hole is movably installed inside the fixing block.

[0013] Preferably, a soft layer is fixedly disposed inside the inner sleeve, and the soft layer is made of synthetic rubber.

[0014] Preferably, a wear-resistant layer is fixedly installed on the inner side of the inner rubber sleeve, and the material of the wear-resistant layer is polyurethane rubber.

[0015] Compared with the prior art, this utility model provides a quick-replacement bushing for automobile chassis, which has the following advantages: When the inner rubber sleeve of the automobile chassis bushing body is damaged after long-term use, the staff needs to remove it for inspection. By sliding the fixing rod and the reinforcing plate upward inside the slide groove, the fixing rod drives the inner rubber sleeve to move outward inside the automobile chassis bushing body and pull it out, which makes it convenient for the staff to replace the new inner rubber sleeve. This avoids the problem that the inner rubber sleeve is difficult to remove after being damaged and sticking to the inner wall of the automobile chassis bushing body, which reduces the maintenance efficiency of the automobile chassis bushing.

Detailed Implementation

[0022] 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.

[0023] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a quick-change bushing for automobile chassis.

[0024] Please see Figures 1-5 A quick-change bushing for an automobile chassis includes an automobile chassis bushing body 1, an inner rubber sleeve 101 disposed inside the automobile chassis bushing body 1, and an inner shaft 102 fixedly installed inside the inner rubber sleeve 101. A groove 103 is provided on the top of the automobile chassis bushing body 1, and sliding grooves 104 are provided at the front and rear ends of the inner wall of the automobile chassis bushing body 1, with the top of the sliding groove 104 communicating with the groove 103. A fixing rod 105 fixedly connected to the inner rubber sleeve 101 is slidably installed inside the sliding groove 104, and there are two sets of fixing rods 105 at each end. A reinforcing plate 106 is fixedly connected between each set of fixing rods 105.

[0025] With the above-described structural design, when the quick-change bushing for the automotive chassis needs replacement after prolonged use, the inner rubber sleeve 101 may crack or break after long-term use. Workers can pull the fixing rod 105 upwards, causing the fixing rod 105 and the reinforcing plate 106 to slide upwards within the slide groove 104. This allows the fixing rod 105 to pull the inner rubber sleeve 101 upwards within the automotive chassis bushing body 1 and out, facilitating the replacement of the new inner rubber sleeve 101. This improves the maintenance efficiency of the automotive chassis bushing body 1 and avoids the problem of the inner rubber sleeve 101 sticking to the inner wall of the automotive chassis bushing body 1 after damage, making it difficult to remove and reducing the maintenance efficiency of the automotive chassis bushing. The reinforcing plate 106 is fixedly connected between the fixing rods 105, allowing the fixing rods 105 to be more firmly fixed inside the slide groove 104.

[0026] Furthermore, a sealing plate 107 is movably installed on the top of the groove 103, and a stop block 108 is fixedly installed on the front and rear ends of the bottom of the sealing plate 107, with the stop block 108 located on top of the fixing rod 105. When the sealing plate 107 covers the top of the groove 103 for sealing, the stop block 108 is positioned on top of the fixing rod 105 to limit its movement, thereby limiting and fixing the fixing rod 105 and the reinforcing plate 106 inside the slide groove 104, making the inner rubber sleeve 101 more securely installed.

[0027] Furthermore, fixing blocks 2 are fixedly installed on both sides of the bottom of the sealing plate 107, and limiting plates 109 extending into the limiting grooves of the fixing blocks 2 are fixedly installed on both sides of the inner wall of the groove 103. A spring 201 is fixedly installed inside the fixing block 2. A first limiting hole 110 is opened inside the limiting plate 109, and a second limiting hole 111 is opened on both sides of the sealing plate 107. A limiting block 202 extending into the first limiting hole 110 and the second limiting hole 111 is movably installed inside the fixing block 2. When the sealing plate 107 is sealed at the top of the groove 103, the limiting plate 109 slides into the limiting groove inside the fixing block 2. At this time, under the elastic force of the spring 201, the limiting block 202 extends upward and extends into the first limiting hole 110 and the second limiting hole 111 for limiting, thereby fixing the sealing plate 107 at the top of the groove 103.

[0028] Furthermore, a soft layer 3 is fixedly disposed inside the inner bushing 101, and the soft layer 3 is made of synthetic rubber. Since the soft layer 3 is made of synthetic rubber, it has excellent oil resistance and good elasticity, thereby increasing the service life of the bushing.

[0029] Furthermore, a wear-resistant layer 4 is fixedly installed on the inner side of the inner rubber sleeve 101, and the material of the wear-resistant layer 4 is polyurethane rubber. Since the wear-resistant layer 4 is made of polyurethane rubber, it has strong wear resistance and extremely high tear strength, thereby improving the toughness of the inner rubber sleeve 101 and extending its service life.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
