Description

Technical Field

[0001] This utility model relates to the field of tensioner adjustment technology, specifically a bidirectional adjustable timing tensioner device for LADA engines. Background Technology

[0002] The LADA engine bidirectional adjustable timing tensioner is a device used in engine timing chain or timing belt systems to ensure accurate and reliable engine valve timing. In addition, LADA brand engines are not typically designed with extremely high adjustment precision as their core design goal, so mechanical adjustment is suitable for LADA engines.

[0003] Without a smooth operating drive mechanism, the tensioner may experience frequent adjustment fluctuations, resulting in uneven tension of the timing chain, which in turn affects the engine's operating accuracy and may even generate unnecessary noise.

[0004] Secondly, without an adaptive adjustment function, the tensioner cannot automatically adjust according to the belt tension, which may cause the chain to be too loose or too tight, thus affecting the normal operation of the engine.

[0005] Finally, if the tensioner cannot be installed quickly, it may take a long time to disassemble and install, increasing maintenance costs and downtime. Utility Model Content

Detailed Implementation

[0028] 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.

[0029] Example 1:

[0030] Please see Figures 1-5 A bidirectional adjustable timing tensioner device for a LADA engine includes a main body 1, a drive mechanism, an adaptive component, and a mounting mechanism. The drive mechanism includes a mounting bracket 2, a motor 3, a drive rod 4, and a first bearing 5. The mounting bracket 2 is mounted on both sides of the main body 1. The motor 3 is fixedly mounted in the mounting bracket 2. The drive rod 4 is mounted on the main body 1 and rotatably connected to the main body 1. The first bearing 5 is mounted on both sides of the main body 1 and rotatably connected to the main body 1 and the drive rod 4, respectively. The adaptive component includes an adjusting block 6, a mating block 7, and a first spring 8. The adjusting block 6 is mounted on the main body 1 and slidably connected to the main body 1. The mating block 7 is mounted inside the adjusting block 6 and slidably connected to the adjusting block 6 and matingly connected to the drive rod 4, respectively. The first spring 8 is mounted on the adjusting block 6, and its other end is fixedly connected to the main body 1.

[0031] In this embodiment, the driving mechanism includes a mounting frame 2, a motor 3, a drive rod 4, and a first bearing 5. In use, the motor 3 in the mounting frame 2 directly drives the active member 14 to rotate, causing the driven member 15, which is meshed with the active member 14, to rotate and drive the drive rod 4 to rotate inside the main body 1. The rotation of the drive rod 4 means that the first bearing 5 installed in the mounting sleeve 19 also starts to rotate due to the cooperation between the first limiting block 16 and the first limiting groove 18. In order to make the drive rod 4 rotate more smoothly inside the main body 1, the limiting plate 17 on the drive rod 4 also rotates inside the main body 1. The presence of the limiting plate 17 also protects the position of the drive rod 4 from displacement when the adjusting block 6 on the drive rod 4 is subjected to force.

[0032] In this embodiment, the adaptive component includes an adjusting block 6, a mating block 7, and a first spring 8. During use, the rotation of the drive rod 4 causes the mating block 7, which is threadedly engaged with the drive rod 4, to be subjected to force. It is also affected by the second limiting block 21 on the mating block 7 and the second limiting groove 20 inside the adjusting block 6, allowing the mating block 7 to slide inside the adjusting block 6. When the mating block 7 reaches one end of the adjusting block 6, it pushes the adjusting block 6 to slide on the through rod 23 on the main body 1. At the same time, the first spring 8 installed in the mounting groove 22 is stretched, so that when the adjusting block 6 faces the high frequency of belt tightening, it can be adjusted under the action of the mating block 7 and the second limiting groove 20. Furthermore, under the action of the first spring 8, the adjusting block 6 can reset after a brief and small-distance positional change.

[0033] In this embodiment, the installation mechanism includes a fixing bolt 9, a placement plate 10, a tensioning wheel 11, a second spring 12, and a positioning frame 13. During use, after replacing the tensioning wheel 11, a second installation is required. First, the placement plate 10 is placed on the adjusting block 6. Then, the fixing bolt 9 is inserted into the placement plate 10 and tightened. The fixing bolt 9 is then forced into the adjusting block 6 and engages with the threaded hole 26 on the positioning frame 13, allowing the positioning rod 25 on the positioning frame 13 to slide within the adjusting block 6. As the fixing bolt 9 rotates, the positioning frame 13 moves a greater distance within the adjusting block 6, compressing the second spring 12. The positioning rod 25 on the positioning frame 13 is also inserted into the positioning hole 27 in the placement plate 10. When the fixing bolt 9 engages with the threaded hole 26 on the adjusting block 6, the fixing bolt 9 stops rotating. The placement plate 10 is then fixed in position, and the tensioning wheel 11 is limited to the placement plate 10. The second bearing 24 further facilitates smoother rotation of the tensioning wheel 11.

[0034] Example 2:

[0035] In summary, during use, first check the tensioning wheel 11. If the tensioning wheel 11 is damaged, it needs to be replaced. After replacing the tensioning wheel 11, it needs to be reinstalled. At this time, first place the placement plate 10 on the adjusting block 6, then insert the fixing bolt 9 into the placement plate 10, and then tighten the fixing bolt 9. At this time, the fixing bolt 9 is forced into the interior of the adjusting block 6 and connects with the threaded hole 26 on the positioning frame 13, so that the positioning rod 25 on the positioning frame 13 can slide in the adjusting block 6. As the fixing bolt 9 rotates, the positioning frame 13 moves up and down a greater distance in the adjusting block 6. Furthermore, the positioning frame 13 compresses the second spring 12, and the positioning rod 25 on the positioning frame 13 is also inserted into the positioning hole 27 in the placement plate 10. When the fixing bolt 9 engages with the threaded hole 26 on the adjusting block 6, the fixing bolt 9 stops rotating, and the position of the placement plate 10 is fixed at this time. The tension wheel 11 is limited to the placement plate 10, and the second bearing 24 acts to make the rotation of the tension wheel 11 smoother. At this time, the main body 1 can be installed in place. Then, according to the needs of the drive device, the motor 3 in the mounting frame 2 drives the active component 14 to rotate, so that it engages with the active component 14. The driven member 15 rotates, causing the drive rod 4 to rotate inside the main body 1. The rotation of the drive rod 4 means that the first bearing 5 installed in the mounting sleeve 19 also begins to rotate due to the engagement between the first limiting block 16 and the first limiting groove 18. In order to make the rotation of the drive rod 4 inside the main body 1 more stable, the limiting plate 17 on the drive rod 4 also rotates inside the main body 1. The presence of the limiting plate 17 also protects the position of the drive rod 4 from displacement when the adjusting block 6 on the drive rod 4 is subjected to force. The rotation of the drive rod 4 causes the mating block 7, which is threadedly engaged with the drive rod 4, to be subjected to force. Furthermore, due to the action of the second limiting block 21 on the mating block 7 and the second limiting groove 20 inside the adjusting block 6, the mating block 7 can slide inside the adjusting block 6. When the mating block 7 reaches one end of the adjusting block 6, it pushes the adjusting block 6 to slide on the through rod 23 on the main body 1. At the same time, the first spring 8 installed in the mounting groove 22 is stretched, so that when the adjusting block 6 faces the high frequency of belt tightening, it can be adjusted under the action of the mating block 7 and the second limiting groove 20. And due to the action of the first spring 8, the adjusting block 6 can be reset after a short and small distance position change.

[0036] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
