Description

Technical Field

[0001] This utility model relates to the field of maintenance technology for military vehicle transmission systems, specifically a tool for quickly aligning the friction plates of a military vehicle steering clutch. Background Technology

[0002] In the steering clutches of military vehicles, the friction plates are key transmission components, and their gear alignment accuracy directly affects the clutch's engagement performance and operational stability.

[0003] Traditional friction plate installation methods primarily rely on manual alignment. This involves stacking the friction plates of the steering clutch together, then attaching iron rods to the sidewalls of the friction plates from different positions, and finally hammering them into the teeth of the friction plates to complete the alignment. However, this method, due to the direct collision between the iron rods and the friction plate teeth, can cause deformation of the friction plate teeth, thus affecting the clutch's transmission efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a tool for quickly aligning the friction plates of a military vehicle steering clutch.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A tool for quickly aligning friction plates of a steering clutch in a military vehicle includes a tooth-aligning ring and a collar located below the tooth-aligning ring, wherein the tooth-aligning ring and the collar are coaxially arranged.

[0007] The aforementioned toothed ring has several connecting blocks fixed to the bottom of its outer side wall, and the aforementioned collar has connecting pieces fixed to the connecting blocks on its outer side wall. A gap is provided between the connecting blocks and the connecting pieces to allow the collar to rotate relative to the toothed ring.

[0008] The bottom of the inner wall of the aforementioned toothed ring is provided with a chamfer for guidance, and a locking block is fixedly provided on the inner wall of the aforementioned collar. When the locking block rotates with the collar to the maximum angle, the top side wall of the locking block aligns with the chamfer side, forming the guide area of ​​the friction plate.

[0009] Preferably, the connecting block has a rod-shaped structure in the middle and plate-shaped structures on both sides. The connecting piece is slidably engaged with the rod-shaped structure of the connecting block, and the plate-shaped structure of the connecting block restricts the rotation of the connecting piece relative to the connecting block.

[0010] Preferably, there are four connecting blocks, and the four connecting blocks are set at equal angles.

[0011] Preferably, the size of the bottom cross-section of the card block is smaller than the size of the top cross-section.

[0012] Preferably, handles for applying force to the toothed ring are fixed on both sides of the top of the toothed ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. When aligning the friction plates of the steering clutch, move the toothed ring and collar in the direction of the friction plates. Under the action of the friction plates and the locking block, the friction plates will rotate with the locking block. When the locking block rotates to its maximum angle, if you continue to move the toothed ring and collar in the direction of the friction plates, the locking block can drive the friction plates to rotate and move the friction plates into the toothed ring through the chamfer at the bottom of the toothed ring, thus completing the tooth alignment operation of the friction plates. This reduces the resistance encountered by the friction plates during the tooth alignment process, reduces the probability of deformation of the friction plate teeth due to direct collision, and reduces the impact on the transmission efficiency of the clutch.

[0015] 2. By limiting the rotation angle of the connecting piece relative to the connecting block through the connection relationship between the connecting block and the connecting piece, the rotation angle of the collar relative to the toothed ring can be limited. This allows the friction piece on the clamping block to smoothly transition into the chamfer after the collar and the clamping block rotate, reducing the squeezing force of the clamping block on the friction piece.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0025] Example

[0026] like Figures 1-4 As shown, a tool for quickly aligning friction plates of a military vehicle steering clutch includes a toothed ring 11 and a collar 21 located below the toothed ring 11. The toothed ring 11 and the collar 21 are coaxially arranged. The inner sidewall of the toothed ring 11 is provided with teeth. The teeth on the inner sidewall of the toothed ring 11 are used to hold the teeth of the friction plate and constrain the aligned friction plate after being acted upon by the collar 21 to the aligned state.

[0027] Handles 13 are fixed on both sides of the top of the toothed ring 11 to apply force to the toothed ring 11. The toothed ring 11 can be pulled up or down by the handles 13. In addition, the toothed ring 11 can be rotated by the handles 13 to move the position of the toothed ring 11, thereby achieving more flexible operation and improving the ease of use of the tool and the efficiency of tooth setting.

[0028] In one embodiment, such as Figures 2-4 As shown, several connecting blocks 12 are fixed to the bottom of the outer side wall of the toothed ring 11, and a connecting piece 22 that engages with the connecting blocks 12 is fixed to the outer side wall of the collar 21. A gap is provided between the connecting blocks 12 and the connecting piece 22 to allow the collar 21 to rotate relative to the toothed ring 11. A chamfer 111 for guidance is provided at the bottom of the inner side wall of the toothed ring 11, and a locking block 23 is fixed to the inner side wall of the collar 21. When the locking block 23 rotates with the collar 21 to the maximum angle, the top side wall of the locking block 23 aligns with the side edge of the chamfer 111, forming a friction. Under the action of connecting block 12 and connecting plate 22, the guide area of ​​the friction plate allows the collar 21 to rotate only slightly relative to the toothed ring 11. After the collar 21 rotates with the connecting plate 22, when the connecting plate 22 rotates to its maximum angle, the top side wall of the locking block 23 aligns with the side edge of the chamfer 111. At this time, the friction plate, after being acted upon by the collar 21 and locking block 23, will enter the toothed ring 11 from the chamfer 111 at the bottom of the toothed ring 11 and then be locked in the toothed ring 11, maintaining the alignment of the stacked friction plates. The effect is that, through the alignment of the locking block 23 with the side edge of the chamfer 111, the friction plate can smoothly transition from the position of the locking block 23 into the toothed ring 11, reducing the resistance encountered by the friction plate during the tooth alignment process, reducing the probability of deformation of the friction plate teeth due to direct collision, and reducing the impact on the transmission efficiency of the clutch.

[0029] In one embodiment, such as Figures 2-3As shown, the connecting block 12 has a rod-shaped structure in the middle and plate-shaped structures on both sides. The connecting piece 22 is slidably engaged with the rod-shaped structure of the connecting block 12. The plate-shaped structure of the connecting block 12 restricts the rotation of the connecting piece 22 relative to the connecting block 12. By setting the rod-shaped structure on the connecting block 12, the connecting piece 22 can slide along the rod-shaped structure. At the same time, the plate-shaped structure plays a limiting role to prevent the connecting piece 22 from undergoing additional angular displacement, thereby ensuring that the rotation range of the collar 21 relative to the toothed ring 11 is controllable and improving the accuracy and stability of the friction plate alignment.

[0030] In one embodiment, such as Figures 1-4 As shown, there are four connecting blocks 12. The four connecting blocks 12 are set at equal angles. The four connecting blocks 12 distributed at equal angles can provide uniform force support, making the collar 21 rotate more smoothly relative to the toothed ring 11, reducing skew and shaking, improving the coaxiality of the overall structure, and thus ensuring that the friction plates can be aligned more accurately.

[0031] In one embodiment, such as Figures 2-4 As shown, the bottom cross-section of the locking block 23 is smaller than the top cross-section. The locking block 23 adopts a design where the bottom dimension is smaller than the top dimension, so that when it is rotated to the maximum angle, it can form a smoother transition area with the chamfer 111 of the inner sidewall of the tooth ring 11, reducing the resistance encountered by the friction plate during tooth alignment, improving the guiding and alignment efficiency of the friction plate, and at the same time reducing the squeezing effect of the locking block 23 on the friction plate to avoid deformation.

[0032] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
