Description

Technical Field

[0001] This utility model relates to the field of tractor technology, specifically to an adjustable tractor bushing assembly. Background Technology

[0002] A tractor is a type of power machinery that uses an internal combustion engine as its core power source, is equipped with a powerful traction system and multi-functional operating interfaces. Its core definition lies in providing efficient power support for agricultural production and engineering operations. Through switchable implement or equipment interfaces, it achieves power transmission and expands operational functions. In the agricultural field, it is a core piece of equipment ensuring food production. It can perform basic farmland operations such as tilling, harrowing, and sowing, as well as tow harvesters for crop harvesting. Furthermore, it can be integrated with irrigation equipment and fertilization machinery to automate field management, significantly reducing labor costs and improving farming efficiency.

[0003] A tractor bushing assembly is an integrated component installed at key connection points in the tractor's transmission system, suspension system, or power take-off device. It consists of a bushing body, connecting flanges, seals, and reinforcement structures. Its core function is to provide stable structural support and protection for power transmission and mechanical connections between various functional components of the tractor. An adjustable tractor bushing assembly is a type of bushing assembly designed to adjust the wheel track. By adjusting the fixed position of the drive wheel hub, which is secured using arc-shaped clips, on the wheel hub adjustment shaft, the wheel track can be adjusted.

[0004] Considering that existing adjustable tractor bushing assemblies typically require tightening multiple fixing bolts to install and remove the two arc-shaped slips in order to adjust the position of the drive hub, and that the pre-tightening and positioning of the two arc-shaped slips during installation is poor, the torque of the multiple fixing bolts is not uniform during installation, and the fixing bolts are prone to loosening after long-term use, which reduces the fixing effect of the arc-shaped slips and thus reduces the performance of the tractor bushing assembly. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable tractor sleeve assembly.

[0006] To achieve this objective, the present invention adopts the following technical solution: An adjustable tractor bushing assembly is provided, including a half-shaft sleeve, a hub adjusting shaft, a drive hub, a fixing mechanism, and a reinforcing mechanism. The hub adjusting shaft is fixedly installed on one end of the half-shaft sleeve, the drive hub is sleeved on the hub adjusting shaft, the fixing mechanism is used to fix the drive hub, and the reinforcing mechanism is used to reinforce the fixing mechanism. The fixing mechanism includes an arc-shaped slip one, an arc-shaped slip two, and a pressing block. Arc-shaped slip one is fixedly installed on the drive wheel hub and has a through groove. Arc-shaped slip two is inserted into the through groove via a snap-fit. The pressing block is slidably installed on arc-shaped slip one and is inserted into the snap-fit. Through the insertion of the pressing block and the snap-fit, the snap-fit ​​is compressed, allowing arc-shaped slip one and arc-shaped slip two to perform pre-tightening and positioning functions.

[0007] Furthermore, the fixing mechanism also includes a moving mechanism and a limiting mechanism. The arc-shaped slip one and the arc-shaped slip two are connected by fixing bolts. The moving mechanism is used to drive the extrusion block to move, and the limiting mechanism is used to limit the moving mechanism.

[0008] Furthermore, the moving mechanism includes a moving plate and a hinge block. The pressing block has an inclined groove. The moving plate is slidably mounted on the arc-shaped clamp. The moving plate passes through the inclined groove through a fixing rod. The hinge block and the moving plate are connected by a connecting column, and the connecting column passes through the arc-shaped clamp.

[0009] Furthermore, the moving mechanism also includes a telescopic rod, a support column, and an arc-shaped frame. One end of the telescopic rod is hinged to a hinge block, and the telescopic rod is hinged to the support column via a cylindrical block. The support column is fixedly mounted on an arc-shaped latch, and the arc-shaped frame is fixedly mounted to the other end of the telescopic rod. Pulling the arc-shaped frame moves the telescopic rod, thereby moving the moving plate and causing the pressing block to move, engaging or disengaging with the latch. The arc-shaped frame is also connected to the reinforcement mechanism, and it drives the reinforcement mechanism to move.

[0010] Furthermore, the limiting mechanism includes a fixed block and a locking block. The fixed block is fixedly installed on the arc-shaped locking plate, and the locking block and the fixed block are connected by a spring. The locking block and the fixed block are slidably connected, and the locking block is engaged with the arc-shaped frame.

[0011] Furthermore, the reinforcement mechanism includes a ring and a rubber pad. The ring is hinged to the arc-shaped frame via a hinge rod, and the ring is slidably mounted on the arc-shaped clamp via a guide rod. The rubber pad is fixedly mounted on the ring. Pulling the arc-shaped frame can move the ring.

[0012] Furthermore, the reinforcement mechanism also includes a plug rod, with a plug hole on the arc-shaped clamp, the plug rod is fixedly installed on the ring, and the plug rod is plugged into the plug hole.

[0013] Furthermore, the reinforcement mechanism also includes a wear-resistant pad and a wedge. A groove is provided on the ring, and the wear-resistant pad passes through the ring through a T-shaped rod. The wear-resistant pad is slidably connected to the groove. The wedge is fixedly installed on the arc-shaped clamp and is used to compress the T-shaped rod.

[0014] The beneficial effects of this utility model are as follows: This adjustable tractor sleeve assembly, through the setting of a fixing mechanism, a moving mechanism, and a limiting mechanism, enables the extrusion block to extrude and fix the buckle inserted in the through groove, thereby achieving pre-tightening and positioning of the arc-shaped collet and the arc-shaped collet, and at the same time playing a fixing and anti-disengagement role, thus improving the performance of the tractor sleeve assembly. In addition, through the setting of a reinforcement mechanism, the ring can be driven to move, thereby allowing the insertion rod to be inserted into the insertion hole, further limiting the arc-shaped collet, and at the same time driving the wear-resistant pad to extrude and fix the hub adjusting shaft, thereby further improving the fixing effect of the drive hub.

[0019] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0020] Reference Figure 1 and Figure 2 The adjustable tractor bushing assembly shown includes a half-shaft sleeve 1, a hub adjusting shaft 2, a drive hub 3, a fixing mechanism 4, and a reinforcing mechanism 5. The hub adjusting shaft 2 is fixedly installed at one end of the half-shaft sleeve 1 and is used to transmit power to the drive hub 3. The drive hub 3 is sleeved on the hub adjusting shaft 2 and is used to drive the tractor wheel to rotate. At the same time, by adjusting the fixed position of the drive hub 3 on the hub adjusting shaft 2, the wheel track can be adjusted. The fixing mechanism 4 is used to fix the drive hub 3. The fixing mechanism 4 can fix or release the drive hub 3, thereby facilitating the adjustment of the position of the drive hub 3. The reinforcing mechanism 5 is used to reinforce the fixing mechanism 4, thereby further improving the fixing effect of the drive hub 3.

[0021] Reference Figures 2 to 5The fixing mechanism 4 includes an arc-shaped locking slip 41, an arc-shaped locking slip 42, and a pressing block 45. The arc-shaped locking slip 41 is fixedly installed on the drive wheel hub 3, and a through groove 43 is provided on the arc-shaped locking slip 41. The through groove 43 is used to position the arc-shaped locking slip 42, improving the installation efficiency of the arc-shaped locking slip 42. The arc-shaped locking slip 42 is inserted into the through groove 43 through a buckle 44. By inserting the arc-shaped locking slip 42 into the arc-shaped locking slip 41, the arc-shaped locking slip 42 can be installed on the drive wheel hub 3. The arc-shaped locking slip 41 and the arc-shaped locking slip 42 can press and fix the hub adjusting shaft 2, thereby driving the hub 3 to remain fixed. The pressing block 45 is slidably installed on the arc-shaped locking slip 41 and is inserted into the buckle 44. The pressing block 45 is wedge-shaped. Through the movement of the pressing block 45, the pressing block 45 can press the buckle 44, thereby causing the arc-shaped locking slip 42 and the arc-shaped locking slip 41 to produce a pressing and fixing effect.

[0022] Reference Figure 2 The fixing mechanism 4 also includes a moving mechanism 47 and a limiting mechanism 48. The arc-shaped clamp 41 and the arc-shaped clamp 42 are connected by a fixing bolt 46. The fixing bolt 46 further fixes the arc-shaped clamp 41 and the arc-shaped clamp 42. The moving mechanism 47 is used to drive the pressing block 45 to move, so that the pressing block 45 can be inserted into or released from the buckle 44. The limiting mechanism 48 is used to limit the moving mechanism 47, so that the moving mechanism 47 and the pressing block 45 remain fixed.

[0023] Reference Figures 5 to 7 The moving mechanism 47 includes a moving plate 473 and a hinge block 475. The pressing block 45 has an inclined groove 471, which guides the fixed rod 472. The moving plate 473 is slidably mounted on the arc-shaped clamp 41, and the moving plate 473 passes through the inclined groove 471 through the fixed rod 472. The movement of the moving plate 473 can drive the fixed rod 472 to move along the inclined groove 471, thereby driving the pressing block 45 to move. The hinge block 475 is connected to the moving plate 473 by a connecting column 474, which passes through the arc-shaped clamp 41. The movement of the hinge block 475 can drive the connecting column 474 to move, thereby driving the moving plate 473 to move.

[0024] Reference Figures 5 to 7The moving mechanism 47 also includes a telescopic rod 476, a support column 478, and an arc-shaped frame 479. One end of the telescopic rod 476 is hinged to the hinge block 475, and the telescopic rod 476 is hinged to the support column 478 via a cylindrical block 477. By rotating the telescopic rod 476 around the hinge point of the support column 478, the hinge block 475 can be moved. The support column 478 is fixedly installed on the arc-shaped clamp 41. The support column 478 is used to support the telescopic rod 476 and also serves as the rotation center of the telescopic rod 476. The arc-shaped frame 479 is fixedly installed at the other end of the telescopic rod 476. By pulling the arc-shaped frame 479, the telescopic rod 476 can be rotated. The arc-shaped frame 479 is connected to the reinforcement mechanism 5 and is used to move the reinforcement mechanism 5.

[0025] Reference Figure 2 and Figure 8 The limiting mechanism 48 includes a fixing block 481 and a locking block 482. The fixing block 481 is fixedly installed on the arc-shaped locking plate 41, which supports and fixes the fixing block 481. The locking block 482 is connected to the fixing block 481 by a spring 483, and the locking block 482 is slidably connected to the fixing block 481. Through the elastic force of the spring 483, the locking block 482 is always locked with the arc-shaped frame 479 when no external force is applied. The locking effect between the locking block 482 and the arc-shaped frame 479 limits the arc-shaped frame 479, thus keeping the pressing block 45 fixed.

[0026] Reference Figure 9 and Figure 10 The reinforcing mechanism 5 includes a ring 52 and a rubber pad 53. The ring 52 is hinged to the arc frame 479 via a hinge rod 51, and the ring 52 is slidably mounted on the arc-shaped slip 41 via a guide rod 54. By pulling the arc frame 479, the hinge rod 51 can be moved, thereby moving the ring 52. The guide rod 54 is used to guide the ring 52. The rubber pad 53 is fixedly mounted on the ring 52. The rubber pad 53 is used to improve the friction and compression fixing effect between the ring 52 and the arc-shaped slip 41 and the arc-shaped slip 42. The reinforcement mechanism 5 also includes a plug rod 55. The arc-shaped latch 42 has a plug hole 510. The plug rod 55 is fixedly installed on the ring 52 and is plugged into the plug hole 510. The movement of the ring 52 can drive the plug rod 55 to move, so that the plug rod 55 can be plugged into or unplugged from the plug hole 510. When the plug rod 55 is plugged into the plug hole 510, it can further limit and reinforce the arc-shaped latch 42.

[0027] Reference Figure 9 and Figure 10The reinforcement mechanism 5 also includes a wear-resistant pad 57 and a wedge 59. A groove 58 is provided on the ring 52, which guides the wear-resistant pad 57. The wear-resistant pad 57 passes through the ring 52 via a T-shaped rod 56, and the wear-resistant pad 57 is slidably connected to the groove 58. The movement of the T-shaped rod 56 can drive the wear-resistant pad 57 to move, so that the wear-resistant pad 57 contacts and presses against the wheel hub adjusting shaft 2, thereby increasing the friction between the wear-resistant pad and the wheel hub adjusting shaft 2 and further reinforcing the drive wheel hub 3. The wedge 59 is fixedly installed on the arc-shaped clamp 41. The wedge 59 is used to press against the T-shaped rod 56. The movement of the ring 52 can drive the T-shaped rod 56 to move, so that the wedge 59 presses against the T-shaped rod 56.

[0028] Reference Figures 1 to 10 This adjustable tractor sleeve assembly, through its fixed, moving, and limiting mechanisms, allows the pressing block to press and fix the buckle inserted into the through slot, thereby pre-tightening and positioning the arc-shaped slip and the arc-shaped slip together, while also providing a fixing and anti-detachment function, thus improving the performance of the tractor sleeve assembly. In addition, the reinforcing mechanism can drive the ring to move, thereby allowing the insert rod to be inserted into the insertion hole, further limiting the arc-shaped slip, and simultaneously pressing and fixing the wear-resistant pad to the wheel hub adjusting shaft, thereby further improving the fixing effect of the drive wheel hub.
