Description

Technical Field

[0001] This utility model belongs to the technical field of heavy truck accessories, specifically relating to an air spring bracket for heavy trucks that is easy to maintain. Background Technology

[0002] Air spring brackets are key components in heavy-duty truck chassis systems. They are mainly used to fix air springs and ensure that the air springs can stably perform their functions of buffering and shock absorption, adjusting vehicle height, etc. during heavy-duty truck operation. This directly affects the smoothness of the heavy-duty truck's ride, handling stability, and load-bearing safety.

[0003] However, in traditional heavy-duty truck air spring brackets, the air springs are typically fixed to the bracket body by independent bolt assemblies. Each air spring requires the removal of 2-4 sets of bolts to complete the assembly and disassembly. Since heavy-duty trucks are often equipped with multiple air springs (e.g., 4-6) to meet load-bearing requirements, maintenance requires the removal of each set of fixing bolts one by one. This repetitive and tedious operation not only consumes a lot of time but also significantly increases the labor intensity of maintenance personnel, leading to extended downtime maintenance cycles for heavy-duty trucks.

[0004] Meanwhile, existing mounting brackets are mostly fixed to the main body of the bracket by welding, and the height of the mounting bracket cannot be adjusted according to the chassis structure of heavy trucks and the installation height requirements of air springs. When facing the differences in chassis of different models (such as light trucks, medium and heavy trucks), or when heavy trucks undergo body modifications or air spring upgrades and replacements, it is necessary to customize the entire bracket to fit the specific height, resulting in insufficient versatility of the bracket. Utility Model Content

[0005] The purpose of this utility model is to provide an air spring bracket for heavy trucks that is easy to maintain. It solves the technical problems of traditional heavy truck air spring brackets, which require disassembling multiple sets of bolts one by one, which is cumbersome, time-consuming and significantly increases the labor intensity of maintenance personnel, resulting in a longer downtime maintenance cycle for heavy trucks. At the same time, the mounting bracket height cannot be adjusted and the versatility is insufficient, requiring customized brackets for different vehicle models or modification and upgrade needs.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An air spring bracket for heavy trucks, designed for easy maintenance, includes a rectangular tube. First circular holes are provided on both the upper and lower sides of the rectangular tube. A circular fixing block is fitted into the inner wall of each first circular hole. An air spring body is fixedly connected to the upper surface of each circular fixing block. A locking hole is provided inside the circular fixing block. A locking bracket is slidably connected to the inner wall of the rectangular tube. Hollow blocks are fixedly connected to both the upper and lower sides of the inner wall of the rectangular tube. The inner walls of the hollow blocks and the inner walls of the locking holes are both fitted into the surface of the locking bracket. A second rectangular hole is provided on the upper surface of the rectangular tube. The inner wall of the second rectangular hole is slidably connected to the surface of the locking bracket. A first nut is fixedly connected to the upper surface of the rectangular tube. A first bolt is threaded onto the inner wall of the first nut. The surface of the first bolt is fitted into the inner wall of the locking bracket.

[0008] The present invention is further configured such that the locking bracket includes a lower horizontal plate, a first rectangular hole, a locking post, a slider, an upper horizontal plate, and a second circular hole. The surface of the lower horizontal plate is slidably connected to the inner wall of the rectangular tube. The first rectangular hole is opened in the lower horizontal plate. The end of the locking post is fixedly connected to the inner wall of the first rectangular hole. The inner wall of the locking hole and the inner wall of the hollow block are both in contact with the surface of the locking post. The upper and lower sides of the slider are fixedly connected to the upper surface of the lower horizontal plate and the bottom of the upper horizontal plate, respectively. The surface of the slider is slidably connected to the inner wall of the second rectangular hole. The second circular hole is opened in the upper horizontal plate. The inner wall of the second circular hole and the upper surface of the upper horizontal plate are both in contact with the surface of the first bolt.

[0009] The present invention is further configured such that limiting rings are fixedly connected to both the left and right sides of the rectangular tube, a vertical plate is fitted to the inner wall of the limiting ring, a mounting bracket is fixedly connected to the bottom of the vertical plate, a third circular hole is opened inside the vertical plate, a second bolt is fitted to the inner wall of the third circular hole and the side of the vertical plate, a second nut is threaded to the surface of the second bolt, and a first connecting block is fixedly connected to the side of the second nut and the upper surface of the rectangular tube.

[0010] The present invention is further configured such that a ring is fixedly connected to the upper surface of the rectangular tube, the inner wall of the ring is in contact with the surface of the circular fixing block, a positioning groove is provided on the upper surface of the ring, a fourth circular hole is provided inside the circular fixing block, a positioning post is fixedly connected to the inner wall of the fourth circular hole, and the surface of the positioning post is in contact with the inner wall of the positioning groove.

[0011] The present invention is further configured such that a groove is provided on the back of the lower horizontal plate, a first magnetic block is fixedly connected to the inner wall of the groove, and a second connecting block is fixedly connected to both the upper and lower sides of the inner wall of the rectangular tube.

Through the cooperation of a rectangular tube, a first circular hole, a circular fixing block, a locking hole, a locking bracket, a hollow block, a second rectangular hole, a first nut, and a first bolt, maintenance personnel only need to tighten the three first bolts used to fix the locking bracket to complete the disassembly and assembly of all air spring bodies on the bracket, thus making the maintenance process more convenient. At the same time, when the locking pin on the locking bracket separates from the locking hole, the attraction between the first and second magnetic blocks prevents the locking bracket from sliding after being vibrated. Therefore, when disassembling the air spring body, the locking pin will not be reinserted into the locking hole due to vibration, thus preventing the disassembly of the remaining air spring bodies from being affected.

[0015] This utility model provides an air spring bracket for heavy trucks that is easy to maintain. Through the cooperation of a limiting ring, a vertical plate, a mounting bracket, a third circular hole, a second bolt, a second nut, and a first connecting block, the mounting bracket can be fixed below a rectangular tube. At the same time, by setting multiple third circular holes on the vertical plate, the user can adjust the distance between the mounting bracket and the rectangular tube according to different installation requirements by changing the position of the second bolt on the vertical plate.

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.

[0032] like Figures 1 to 12As shown, an air spring bracket for heavy trucks that is easy to maintain includes a rectangular tube 1. First circular holes 2 are provided on both the upper and lower sides of the rectangular tube 1. A circular fixing block 3 is fitted into the inner wall of the first circular hole 2. An air spring body 4 is fixedly connected to the upper surface of the circular fixing block 3. A locking hole 5 is provided inside the circular fixing block 3. A locking bracket 6 is slidably connected to the inner wall of the rectangular tube 1. Hollow blocks 7 are fixedly connected to both the upper and lower sides of the inner wall of the rectangular tube 1. The inner walls of the hollow blocks 7 and the inner walls of the locking holes 5 are both fitted into the surface of the locking bracket 6. A second rectangular hole 8 is provided on the upper surface of the rectangular tube 1. The inner wall of the second rectangular hole 8 is slidably connected to the surface of the locking bracket 6. A first nut 9 is fixedly connected to the upper surface of the rectangular tube 1. A first bolt 10 is threadedly connected to the inner wall of the first nut 9. The surface of the first bolt 10 is fitted into the inner wall of the locking bracket 6.

[0033] The locking bracket 6 includes a lower horizontal plate 61, a first rectangular hole 62, a locking post 63, a slider 64, an upper horizontal plate 65, and a second circular hole 66. The surface of the lower horizontal plate 61 is slidably connected to the inner wall of the rectangular tube 1. The first rectangular hole 62 is opened in the lower horizontal plate 61. The end of the locking post 63 is fixedly connected to the inner wall of the first rectangular hole 62. The inner wall of the locking hole 5 and the inner wall of the hollow block 7 are both in contact with the surface of the locking post 63. The upper and lower sides of the slider 64 are fixedly connected to the upper surface of the lower horizontal plate 61 and the bottom of the upper horizontal plate 65, respectively. The surface of the slider 64 is slidably connected to the inner wall of the second rectangular hole 8. The second circular hole 66 is opened in the upper horizontal plate 65. The inner wall of the second circular hole 66 and the upper surface of the upper horizontal plate 65 are both in contact with the surface of the first bolt 10.

[0034] A ring 18 is fixedly connected to the upper surface of the rectangular tube 1. The inner wall of the ring 18 is in contact with the surface of the circular fixing block 3. A positioning groove 19 is provided on the upper surface of the ring 18. A fourth circular hole 20 is provided inside the circular fixing block 3. A positioning post 21 is fixedly connected to the inner wall of the fourth circular hole 20. The surface of the positioning post 21 is in contact with the inner wall of the positioning groove 19.

[0035] A groove 22 is provided on the back of the lower horizontal plate 61. A first magnetic block 23 is fixedly connected to the inner wall of the groove 22. A second connecting block 24 is fixedly connected to both the upper and lower sides of the inner wall of the rectangular tube 1. The second connecting block 24 is located in the groove 22. A second magnetic block 25 is fixedly connected to the front of the second connecting block 24. The first magnetic block 23 and the second magnetic block 25 are aligned. The back of the first magnetic block 23 is the S pole, and the front of the second magnetic block 25 is the N pole.

[0036] It should be noted that when the circular fixing block 3 is inserted into the first circular hole 2, the circular fixing block 3 is limited by the first circular hole 2. Through the cooperation of the ring 18, the positioning groove 19 and the positioning post 21, the locking hole 5 can be aligned with the locking post 63 on the locking bracket 6 after the circular fixing block 3 is inserted into the first circular hole 2 of the post.

[0037] The lower horizontal plate 61 can slide freely back and forth within the rectangular tube 1, and the slider 64 can slide freely back and forth within the second rectangular hole 8. After the locking pin 63 in the lower horizontal plate 61 is inserted into the locking hole 5 and the hollow block 7, the air spring body 4 can be fixed on the rectangular tube 1 by the cooperation of the locking pin 63, the locking hole 5, the circular fixing block 3 and the first circular hole 2. The hollow block 7 can limit the end of the locking pin 63. When the locking pin 63 is removed from the locking hole 5, the circular fixing block 3 can be directly removed from the first circular hole 2. At this time, the air spring body 4 can be removed from the rectangular tube 1. At the same time, when the locking pin 63 on the locking bracket 6 is separated from the locking hole 5, the attraction between the first magnetic block 23 and the second magnetic block 25 can prevent the locking bracket 6 from sliding after being vibrated. Therefore, when disassembling the air spring body 4, the locking pin 63 will not be reinserted into the locking hole 5 due to vibration, thus affecting the disassembly of the remaining air spring body 4.

[0038] When the locking pin 63 is inserted into the locking hole 5, the second round hole 66 is aligned with the first nut 9. Then, by passing the first bolt 10 through the second round hole 66 and screwing it into the first nut 9, the lower horizontal plate 61 can be fixed in the rectangular tube 1, and the locking pin 63 cannot be separated from the locking hole 5. When the first bolt 10 is separated from the first nut 9, the lower horizontal plate 61 can slide freely in the rectangular tube 1.

[0039] like Figures 1 to 11 As shown, limiting rings 11 are fixedly connected to both the left and right sides of the rectangular tube 1. A vertical plate 12 is fitted to the inner wall of the limiting ring 11. A mounting bracket 13 is fixedly connected to the bottom of the vertical plate 12. A third circular hole 14 is opened inside the vertical plate 12. A second bolt 15 is fitted to the inner wall of the third circular hole 14 and the side of the vertical plate 12. A second nut 16 is threaded to the surface of the second bolt 15. A first connecting block 17 is fixedly connected to the side of the second nut 16 and the upper surface of the rectangular tube 1.

[0040] It should be noted that when the vertical plate 12 is inserted into the limiting ring 11, the vertical plate 12 can be positioned by the limiting ring 11. When the second bolt 15 passes through the third round hole 14 and is screwed into the second nut 16, the mounting bracket 13 can be fixed below the rectangular tube 1 by the cooperation of the limiting ring 11, the vertical plate 12, the third round hole 14, the second bolt 15, the second nut 16 and the first connecting block 17. At the same time, by setting multiple third round holes 14 on the vertical plate 12, the user can adjust the distance between the mounting bracket 13 and the rectangular tube 1 according to different installation requirements by changing the position of the second bolt 15 on the vertical plate 12.

[0041] The working principle of this utility model is as follows: When disassembling the air spring body 4 on the bracket, firstly, by turning the first bolt 10, the first bolt 10 is separated from the first nut 9, and the first bolt 10 is pulled out from the second round hole 66. After the three first bolts 10 on the upper horizontal plate 65 are separated from the upper horizontal plate 65, the locking pin 63 is moved out from the locking hole 5 by pushing the upper horizontal plate 65. At this time, all the air spring bodies 4 on the bracket can be directly removed from the rectangular tube 1.

[0042] When the hollow spring body needs to be installed, first insert the circular fixing block 3 into the first circular hole 2 and make the positioning pin 21 contact the positioning groove 19. At this time, through the cooperation of the ring 18, the positioning groove 19 and the positioning pin 21, the locking hole 5 can be aligned with the locking pin 63 on the locking bracket 6. Then, by moving the upper horizontal plate 65, the locking pin 63 is inserted into the locking hole 5 and the hollow block 7. At this time, through the cooperation of the locking pin 63, the locking hole 5, the circular fixing block 3 and the first circular hole 2, the air spring body 4 can be fixed on the rectangular tube 1, and the hollow block 7 can limit the end of the locking pin 63. When the locking pin 63 is inserted into the locking hole 5, the second circular hole 66 is aligned with the first nut 9. Then, by passing the first bolt 10 through the second circular hole 66 and screwing it into the first nut 9, the lower horizontal plate 61 can be fixed in the rectangular tube 1, and the locking pin 63 cannot be separated from the locking hole 5.

[0043] When it is necessary to adjust the distance between the mounting bracket 13 and the rectangular tube 1, first, by turning the second bolt 15, the second bolt 15 is separated from the second nut 16, and the second bolt 15 is pulled out from the third round hole 14. Then, by moving the mounting bracket 13, the distance between the mounting bracket 13 and the rectangular tube 1 is adjusted. When the distance between the mounting bracket 13 and the rectangular tube 1 reaches a suitable value, the second bolt 15 is inserted into the corresponding third round hole 14, and the second bolt 15 is screwed into the second nut 16. At this time, through the cooperation of the limiting ring 11, the vertical plate 12, the third round hole 14, the second bolt 15, the second nut 16 and the first connecting block 17, the mounting bracket 13 can be fixed below the rectangular tube 1.

[0044] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
