Description

Technical Field

[0001] This utility model belongs to the field of heavy vehicle technology, and specifically relates to a steering adjustment joint for heavy vehicles. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] Currently, heavy-duty vehicles, especially mining dump trucks and highway heavy trucks, basically adopt hydraulic steering adjustment mechanisms. The steering adjustment structure is mostly a threaded steering joint with a groove in the middle. The groove is a half groove, and it is fixed by tightening bolts and nuts.

[0004] The semi-groove bolt and nut tightening structure inevitably produces uneven stress, meaning that the size of the semi-groove will inevitably be inconsistent after the bolt and nut are tightened. This means that the semi-groove will have a smaller gap at the front end and a larger gap at the rear end. If the front thread is tight and the rear thread is loose, after long-term operation, the front thread will inevitably strip or decay, causing heavy vehicles to be unable to steer and posing a safety hazard. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides a heavy-duty vehicle steering adjustment joint that ensures both uniform force distribution and robust connection, enabling long-term stable operation and preventing slippage or rotten teeth, thereby avoiding safety hazards.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A heavy-duty vehicle steering adjustment joint includes a docking device, a connecting flange, connecting bolts, and connecting nuts. The docking device is located at one end of an adjustment rod and is installed by connecting bolts and connecting nuts. The docking device includes an arc-shaped plate, which is symmetrically arranged. Square plates are provided at both ends of the arc-shaped plate, and a semi-circular plate is provided at the lower end of the arc-shaped plate. The lower end of the semi-circular plate is connected to the connecting flange, and a docking structure is provided at the lower end of the connecting flange.

[0008] Furthermore, the arc-shaped plate is fixedly connected to the square plate, and the semi-circular plate is fixedly connected to the arc-shaped plate.

[0009] Furthermore, the connecting bolt includes a first connecting bolt and a second connecting bolt, and the connecting nut includes a first connecting nut and a second connecting nut.

[0010] Furthermore, the square plate is provided with a threaded hole, a first connecting bolt is provided in the threaded hole of the square plate, and a first connecting nut is provided at the end of the first connecting bolt.

[0011] Furthermore, the square plate has several threaded holes spaced apart.

[0012] Furthermore, the semicircular plate is provided with a plurality of threaded holes spaced apart, and a second connecting bolt is provided in the threaded holes of the semicircular plate, and a second connecting nut is provided at the end of the second connecting bolt.

[0013] Furthermore, the second connecting bolt is screwed into the threaded hole on the semi-circular plate and the threaded hole on the connecting flange in sequence.

[0014] Furthermore, the number of threaded holes on the semicircular plate is the same as the number of threaded holes on the connecting flange.

[0015] Furthermore, the inner wall surface of the arc-shaped plate of the docking device is provided with internal threads, and the end of the adjusting rod is provided with external threads. The adjusting rod and the docking device are connected by threads.

[0016] Furthermore, the arc-shaped plates are symmetrically arranged at both ends of the adjusting rod, and there is a gap between the symmetrically arranged arc-shaped plates.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are:

[0018] This utility model is equipped with a docking device. The docking device consists of symmetrically arranged arc-shaped plates that dock together. The arc-shaped plates have a gap between them to form a through groove. After docking, the first connecting bolt and the first connecting nut are used to connect the square plates. Then, the adjusting rod is screwed into the threaded hole formed after the arc-shaped plates dock. Because a through groove is formed after docking, the two ends of the through groove are tightened at the same degree, which will not cause the problem of inconsistent groove width. This makes the thread of the adjusting rod evenly stressed, enabling it to work stably for a long time and avoiding stripping or rotting of the threads, thereby avoiding safety hazards.

[0019] Furthermore, a semi-circular plate is provided at the lower end of the arc plate, which is connected to the connecting flange, thereby realizing the connection between the docking mechanism and the adjusting rod. The docking is firm, ensuring both uniform force distribution and strong connection. Attached Figure Description

[0023] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0024] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a heavy-duty vehicle steering adjustment joint, such as... Figure 1 As shown, it includes a docking device, a connecting flange 5, connecting bolts, and connecting nuts; the docking device is located at one end of the adjusting rod 1, and the docking device is installed by connecting bolts and connecting nuts; the docking device includes an arc plate 2, which is symmetrically arranged; square plates 3 are provided at both ends of the arc plate 2, and a semi-circular plate 4 is provided at the lower end of the arc plate 2. The lower end of the semi-circular plate 4 is connected to the connecting flange 5, and a docking structure 6 is provided at the lower end of the connecting flange 5.

[0025] Specifically, the connecting flange 5 and the docking structure 6 are an integrated structure, a single structural component; the docking structure 6 is used to dock or connect with the rear vehicle parts, and the adjusting rod 1 is also used to connect the parts on the vehicle. By turning the adjusting rod 1 to adjust the depth of screwing into the docking device, the connection length can be adjusted, thereby connecting two parts on the vehicle. The length can be adjusted according to the distance between the parts, improving applicability.

[0026] The symmetrically arranged arc-shaped plates 2 of the docking device are docked together, and there is a gap between the arc-shaped plates 2 to form a through groove. After docking, the first connecting bolt 7 and the first connecting nut 8 are used to connect the square plate 3. Then, the adjusting rod 1 is screwed into the threaded hole formed after the arc-shaped plates 2 are docked. Because a through groove is formed after docking, the two ends of the through groove are tightened at the same degree, and there will be no problem of inconsistent groove width. This makes the thread of the adjusting rod 1 evenly stressed, and can work stably for a long time, avoiding stripping or rotting of the thread, thereby avoiding safety hazards.

[0027] The arc-shaped plate 2 is fixedly connected to the square plate 3, and the semi-circular plate 4 is fixedly connected to the arc-shaped plate 2. The arc-shaped plate 2, the semi-circular plate 4, and the square plate 3 are an integrated structure, forming a single structural component. The lower end of the arc-shaped plate 2 is provided with the semi-circular plate 4, which is connected to the connecting flange 5, thereby realizing the connection between the docking mechanism and the adjusting rod 1. The docking is firm, ensuring both uniform force distribution and strong connection.

[0028] The connecting bolts include a first connecting bolt 7 and a second connecting bolt 9, and the connecting nuts include a first connecting nut 8 and a second connecting nut 10. A threaded hole is provided on the square plate 3, and the first connecting bolt 7 is installed inside the threaded hole of the square plate 3. The first connecting nut 8 is installed at the end of the first connecting bolt 7. Several threaded holes are spaced apart on the square plate 3.

[0029] Specifically, two arc-shaped plates 2 are set, with a square plate 3 at each end of each arc-shaped plate 2 and a semi-circular plate 4 at the bottom of each arc-shaped plate 2.

[0030] When in use, align the square plates 3 of the arc plate 2, ensuring that the threaded holes on the square plates 3 are aligned. After alignment, screw the first connecting bolt 7 into the threaded holes of the square plates 3. After screwing it in, screw the first connecting nut 8 onto the end of the first connecting bolt 7, so that the bottom of the first connecting nut 8 is in close contact with the surface of the square plates 3. This will align the two arc plates 2. A certain gap is left on the inner side of the two arc plates 2. This gap ensures that the middle of the docking device has a through groove after installation, thereby ensuring that the tightening degree of both ends of the docking device is consistent.

[0031] Conventional adjusting joints are semi-grooved, which can easily lead to one end being tight and the other loose after the bolt is screwed in. The through-groove design makes installation more convenient and ensures that the tightening degree at both ends is consistent. It also prevents damage to the threads at the end of adjusting rod 1 after it is screwed in.

[0032] A number of threaded holes are spaced apart on the semicircular plate 4. A second connecting bolt 9 is installed in each of the threaded holes on the semicircular plate 4, and a second connecting nut 10 is installed at the end of the second connecting bolt 9. The second connecting bolt 9 is screwed into the threaded holes on the semicircular plate 4 and the threaded holes on the connecting flange 5 in sequence. The number of threaded holes on the semicircular plate 4 is the same as the number of threaded holes on the connecting flange 5.

[0033] Specifically, during use, align the threaded holes on the semicircular plate 4 and the threaded holes on the connecting flange 5, screw the second connecting bolt 9 into the threaded holes on the semicircular plate 4 and the connecting flange 5 in sequence, and then screw the second connecting nut 10 into the end of the second connecting bolt 9 to connect the semicircular plate 4 and the connecting flange 5, thus realizing the connection between the docking device and the connecting flange 5.

[0034] The inner wall of the arc-shaped plate 2 of the docking device is provided with internal threads, and the end of the adjusting rod 1 is provided with external threads. The adjusting rod 1 and the docking device are connected by threads. The arc-shaped plates 2 are symmetrically arranged at both ends of the adjusting rod 1, and there is a gap between the symmetrically arranged arc-shaped plates 2.

[0035] Specifically, screw the semicircular plate 4 and connecting flange 5 on but not tighten them completely. Then, align the adjusting rod 1 and the arc-shaped plate 2, ensuring accurate thread alignment. Finally, tighten the semicircular plate 4 and connecting flange 5 completely. Note that the semicircular plate 4 and connecting flange should not be tightened prematurely, otherwise thread alignment problems will occur.

[0036] How to use the steering adjustment joint for heavy vehicles:

[0037] In use, the arc-shaped plates 2 are joined together to form a circular hole between them. Since the inner wall of the arc-shaped plates 2 is provided with internal threads, the circular hole formed after the two arc-shaped plates 2 are joined together is a threaded hole. The square plates 3 on the arc-shaped plates 2 are connected by the first connecting bolt 7 and the first connecting nut 8. A certain gap is left at the joint position to form a through groove. The distance between the front and rear ends of the through groove is consistent. The adjusting rod 1 is screwed into the threaded hole formed after the joint. Then, the connecting flange 5 and the semi-circular disc are connected by the second connecting bolt 9 and the second connecting nut 10, thereby realizing the connection between the adjusting rod 1 and the joint structure 6.

[0038] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
