Description

Technical Field

[0001] This utility model belongs to the field of forklift technology, and specifically relates to a high-strength heavy-duty forklift drive axle housing that is easy to assemble. Background Technology

[0002] Currently, in the industrial logistics and warehousing sector, forklifts, as core industrial handling vehicles, are mainly used for loading, unloading, stacking, and short-distance transportation of palletized goods. Their operational stability and structural reliability directly affect warehousing and transportation efficiency. Forklifts are typically driven by fuel engines or batteries, and their technical parameters are key indicators for measuring structural characteristics and working performance. These include rated lifting capacity, load center distance, maximum lifting height, mast tilt angle, maximum travel speed, minimum turning radius, minimum ground clearance, wheelbase, and track width. These parameters collectively determine the forklift's adaptability under different working conditions. As the core component of the forklift's transmission and load-bearing systems, the drive axle housing must withstand the enormous forces and torques during vehicle movement and cargo handling. Its structural strength and ease of assembly and disassembly are crucial to the overall performance of the forklift.

[0003] To improve the load-bearing capacity and service life of drive axle housings, targeted designs have been developed in related technical fields. For example, Chinese patent CN220053398U discloses a high-strength heavy-duty forklift drive axle housing. This drive axle housing, through the arrangement of a transmission device, drive shaft, support block, fixing plate, connecting plate, screws, load-bearing axle housing, and load-bearing column, achieves two core functions: Firstly, by utilizing the cooperation of the support block, fixing plate, and load-bearing column, the stress on the axle housing is effectively distributed, alleviating the problem of structural damage or even breakage of traditional drive axle housings due to excessive forces and torques, thus improving the structural strength and durability of the axle housing. Secondly, the cooperation of the connecting plate and screws, along with nuts, enables the quick installation and disassembly of some components, to some extent solving the problem of inconvenient disassembly when parts of traditional drive axle housings are damaged, providing convenience for daily maintenance. Therefore, it has certain application value in the field of heavy-duty forklifts.

[0004] However, the existing high-strength heavy-duty forklift drive axle housing still has significant structural design flaws in practical applications, resulting in insufficient flexibility in overall disassembly and assembly. Its overall structure is relatively simple, and the core disassembly and assembly method still relies on bolt connections: when disassembly and maintenance of the drive axle housing is required, only one side of the axle housing can be removed by unscrewing the bolts on one side, while the other half of the axle housing remains fixed to the transmission. This design significantly limits subsequent maintenance operations. If the entire transmission needs to be removed, or the other half of the axle housing needs to be removed from the transmission, additional complex bolt removal operations are required. This is not only cumbersome and time-consuming, but repeated disassembly may also cause bolt stripping and wear on the connection points, further increasing maintenance difficulty and cost. In summary, while existing high-strength heavy-duty forklift drive axle housings have improved in terms of structural strength and ease of disassembly and assembly, they have not solved the problem of cumbersome disassembly and assembly processes and cannot meet the demand for efficient maintenance of drive axle housings in industrial scenarios. Therefore, there is still room for improvement in structural design, and it is urgent to optimize its disassembly and assembly structure to improve the overall ease of disassembly and assembly in order to adapt to the actual maintenance needs of heavy-duty forklifts.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A high-strength, heavy-duty forklift drive axle housing that is easy to assemble includes a transmission device body and two half-axle housings. A main shaft is provided in the middle of the transmission device body. A connecting frame is fixedly connected to the top of the main shaft.

[0010] As a preferred technical solution, an external rail is fixedly installed on the middle of the outer side of the half-bridge housing, and an external locking block is slidably connected inside the external rail. A reinforcing arm is fixedly installed on the top of the external locking block, and the top of the reinforcing arm is fixedly connected to the outer side of the support ring.

[0011] As a preferred technical solution, the top view shape of the inner connecting block is I-shaped, and the top view shapes of the inner connecting rail, the outer connecting rail, and the outer connecting block are all convex.

[0012] As a preferred technical solution, the limiting module includes a lead screw and a slot. The lead screw is rotatably connected to the inside of the mounting rail. The two ends of the lead screw have opposite thread directions. Both ends of the lead screw are threadedly connected to sliders. The sliders are slidably connected to the two ends inside the mounting rail. Limiting arms are fixedly installed on the outside of the sliders. The slots are opened on both sides of the bridge housing. The outer ends of the limiting arms are inserted into the slots.

[0013] As a preferred technical solution, the adjustment module includes a fixed plate, which is fixedly installed on one end of the mounting rail.

[0016] First, during the application of this technical solution, by setting up a transmission device body, a half-bridge housing, an installation mechanism, an adjustment module, and a reinforcing structure, the transmission device body can be positioned first during use. The half-bridge housing is fixed by the cooperation of the limiting module and the adjustment module of the installation mechanism. The reinforcing structure enhances the connection strength, the support ring and the support arm ensure the stability of the main shaft, and the internal and external structures achieve precise positioning. Thus, it achieves the effects of convenient installation, structural stability, and strong load-bearing capacity, and solves the problems of the existing technology where the drive axle housing installation relies on a large number of bolts, the structure is easily damaged under stress, and the positioning accuracy is insufficient.

[0017] Secondly, during the application of this technical solution, by setting up an adjustment module, installation mechanism and detachable connection structure, when maintenance is required during use, it is only necessary to operate the adjustment module to release the limit and push the external structure to separate, so that the two half-bridge housings can be removed. Disassembling the transmission device body only requires removing the connecting frame, without the need for complicated bolt disassembly. This achieves the effects of quick disassembly and assembly, efficient maintenance and less wear on parts, and solves the problems of existing technologies where only one side of the drive axle housing can be disassembled, the whole disassembly is cumbersome, and repeated bolt disassembly can easily damage parts.

[0025] Example

[0026] refer to Figures 1 to 6 This embodiment provides a high-strength, heavy-duty forklift drive axle housing that is easy to assemble, comprising a transmission device body 1 and two half-axle housings 2. A main shaft 3 is provided in the middle of the transmission device body 1, and a connecting frame 4 is fixedly connected to the top of the main shaft 3. Support arms 5 are fixedly installed on the upper ends of both sides of the transmission device body 1, and support rings 6 are fixedly installed on the top of the support arms 5. The main shaft 3 is rotatably connected to the inner side of the support ring 6. The main shaft 3 is rotatably connected to the inside of the support ring 6. Mounting mechanisms 7 are fixedly installed on the lower ends of both sides of the support arms 5. The half-axle housings 2 are mounted on both sides of the transmission device body 1 through the mounting mechanisms 7.

[0027] The mounting mechanism 7 includes a mounting rail 71, which is fixedly mounted on the lower outer side of the support arm 5. A limiting module 72 is movably mounted inside the mounting rail 71. The two limiting ends of the limiting module 72 are engaged with the half-bridge housing 2. One end of the mounting rail 71 is fixedly connected to an adjustment module 73, the inner side of which is connected to the outer end of the limiting module 72. During application, the transmission device body 1 is first placed in the preset installation position. The main shaft 3 in the middle of the transmission device body 1 serves as the core of power transmission, and can subsequently be connected to the forklift transmission system to achieve power transmission. The connecting bracket 4 at the top of the main shaft 3 is used for docking with other forklift structures. The transmission device body can be lifted through the connecting bracket 4. 1. Overall stability after installation: To prevent the transmission device body 1 from shifting during forklift operation, the upper support arms 5 on both sides of the transmission device body 1 provide the mounting base for the mounting mechanism 7. The support ring 6 at the top of the support arm 5 is sleeved on the outside of the main shaft 3. The main shaft 3 is rotatably connected to the inside of the support ring 6. The support ring 6 can limit the radial displacement of the main shaft 3, ensuring that the main shaft 3 remains stable during rotation and preventing the main shaft 3 from deviating from the preset trajectory due to vibration, thus affecting the power transmission efficiency. When it is necessary to install the half-bridge housing 2, the operator aligns the two half-bridge housings 2 with the two sides of the transmission device body 1 respectively, and completes the fixation through the mounting mechanism 7 at the lower ends of both sides of the support arm 5. The mounting rail 71 of the mounting mechanism 7 is a limit. Module 72 provides movement space. The two limiting ends of the limiting module 72 can be engaged with the half-axle housing 2. The inner side of the adjusting module 73 at one end of the mounting rail 71 is connected to the outer end of the limiting module 72. The operator can control the movement of the limiting module 72 by operating the adjusting module 73. In specific operation, the adjusting module 73 drives the limiting module 72 to move inside the mounting rail 71, causing the two limiting ends of the limiting module 72 to move towards the half-axle housing 2 until the limiting ends are engaged with the half-axle housing 2, thus completing the fixation of the half-axle housing 2 and the transmission device body 1. The entire installation process does not rely on a large number of bolts, reducing the tedious steps of bolt disassembly compared with existing technologies, greatly improving installation efficiency, and making it more convenient for forklift daily operation. During the travel phase, the main shaft 3 smoothly transmits power to the half-axle housing 2 through the transmission device body 1, driving the forklift to travel. During this process, the support ring 6 continuously limits the main shaft 3 to ensure stable rotation of the main shaft 3. The limiting end of the limiting module 72 is always locked with the half-axle housing 2 to prevent the half-axle housing 2 from disengaging from the transmission device body 1 during the stress process, ensuring reliable connection of the overall structure. If the position of the half-axle housing 2 needs to be adjusted later, simply operate the adjustment module 73 to drive the limiting module 72 to release the locking from the half-axle housing 2, and the half-axle housing 2 can be moved. The operation is convenient and provides convenience for subsequent maintenance or adjustment, effectively solving the problem of the existing technology where the disassembly and assembly of the drive axle housing relies on bolts and the operation is cumbersome.

[0028] refer to Figures 3-6The limiting module 72 includes a lead screw 721 and a slot 722. The lead screw 721 is rotatably connected to the inside of the mounting rail 71. The two ends of the lead screw 721 have opposite thread directions. Both ends of the lead screw 721 are threadedly connected to sliders 723. The sliders 723 are slidably connected to the two ends inside the mounting rail 71. Limiting arms 724 are fixedly installed on the outer side of the sliders 723. The slots 722 are opened on both sides of the bridge housing. The outer ends of the limiting arms 724 are inserted into the slots 722. The adjusting module 73 includes a fixed plate 731. The fixed plate 731 is fixedly installed at one end of the mounting rail 71. An adjusting handle 732 is rotatably connected to the outer side of the fixed plate 731. A locking screw 733 is threadedly connected to one side of the adjusting handle 732. The end of the locking screw 733 passes through the adjusting handle. 732, the inner side of the adjusting handle 732 is connected to the outer end of the lead screw 721. The outer side of the fixed plate 731 has equally spaced ring-shaped locking holes 734. The end of the locking screw 733 is inserted into the inner side of the locking hole 734. During the application of this device, when fixing the half-bridge housing 2, the operator first rotates the adjusting handle 732 of the adjusting module 73. Since the inner side of the adjusting handle 732 is connected to the outer end of the lead screw 721 of the limiting module 72, rotating the adjusting handle 732 will drive the lead screw 721 to rotate inside the mounting rail 71. The threads at both ends of the lead screw 721 have opposite directions, and both ends are threadedly connected to sliders 723. When the lead screw 721 rotates, it will drive the two sliders 723 to move synchronously outward along the inside of the mounting rail 71. The limiting locking arms 724 on the outer side of the sliders 723 The slider 723 moves together until the outer end of the limiting arm 724 is inserted into the slots 722 on both sides of the half-bridge housing 2, completing the limiting and fixing of the half-bridge housing 2. The entire process does not require special tools; the limiting can be achieved simply by rotating the adjusting handle 732. Compared with the bolt-tightening method in the prior art, the operation is simpler and the fixing time is greatly shortened. After fixing, the locking screw 733 on one side of the adjusting handle 732 is turned so that the end of the locking screw 733 passes through the adjusting handle 732 and is inserted into the slot 734 on the outside of the fixing plate 731. The slots 734 on the outside of the fixing plate 731 are arranged in a ring at equal intervals. The locking screw 733 and the slot 734 cooperate to restrict the rotation of the adjusting handle 732, thereby fixing the position of the lead screw 721 and preventing it from rotating when the forklift is in motion. Vibration causes the lead screw 721 to rotate, preventing the limit arm 724 from dislodging from the slot 722 and ensuring a stable and reliable fixed state for the half-bridge housing 2. When it is necessary to disassemble or adjust the half-bridge housing 2, first turn the locking screw 733 in the reverse direction to pull the end of the locking screw 733 out of the slot 734, releasing the restriction on the adjusting handle 732. Then, turn the adjusting handle 732 in the reverse direction, causing the lead screw 721 to rotate in the reverse direction. The sliders 723 at both ends of the lead screw 721 move inward, and the sliders 723 drive the limit arm 724 to be pulled out of the slot 722, thus releasing the restriction on the half-bridge housing 2. This unlocking method does not require disassembling multiple parts, has fewer operation steps, and can quickly complete the disassembly of the half-bridge housing 2, reducing maintenance time and avoiding wear on parts caused by repeated bolt disassembly.Further improve the ease of maintenance of the equipment.

[0029] refer to Figures 1-3 Both ends of the transmission device are rotatably connected to internal connecting blocks 8. Internal connecting rails 9 are fixedly installed on both inner ends of the half-bridge housing 2, with the internal connecting blocks 8 inserted inside the internal connecting rails 9. External connecting rails 10 are fixedly installed on the middle of the outer side of the half-bridge housing 2. External connecting blocks 11 are slidably connected inside the external connecting rails 10. A reinforcing arm 12 is fixedly installed on the top of the external connecting block 11, and the top of the reinforcing arm 12 is fixedly connected to the outer side of the support ring 6. The internal connecting blocks 8 have an I-shaped top view, while the internal connecting rails 9, external connecting rails 10, and external connecting blocks 11 all have a convex top view. During the application of this device, when installing the half-bridge housing 2, first align the two inner ends of the half-bridge housing 2 with the two ends of the transmission device, so that the two ends of the transmission device... The inner connecting block 8 is inserted into the inner rails 9 at both ends of the inner side of the half-bridge housing 2. Through the cooperation of the inner connecting block 8 and the inner rail 9, the initial positioning of the half-bridge housing 2 and the transmission device can be quickly achieved, avoiding lateral displacement of the half-bridge housing 2 during the subsequent fixing process. This lays the foundation for the precise fixing of the subsequent installation mechanism 7. The top view of the inner connecting block 8 is I-shaped, and the top view of the inner rail 9 is T-shaped. This shape adaptation design can increase the contact area between the two, enhance the connection tightness, and prevent the half-bridge housing 2 from sliding relative to the transmission device when subjected to force or vibration, further improving the stability of the initial positioning. After the initial positioning is completed, the operator pushes the outer connecting block 1 inside the outer rail 10 at the middle of the outer side of the half-bridge housing 2. 1. The external locking block 11 slides along the external rail 10 to the designated position. Both the external rail 10 and the external locking block 11 have a convex shape when viewed from above. This convex structure restricts the sliding direction of the external locking block 11, preventing it from detaching from the external rail 10 and ensuring a stable and controllable sliding process. After the top of the reinforcing arm 12 on the top of the external locking block 11 is fixedly connected to the outside of the support ring 6, the reinforcing arm 12 connects the half-axle housing 2 and the support ring 6 into a whole, distributing the load on the half-axle housing 2 and reducing the risk of deformation or damage due to excessive local stress. Simultaneously, it further strengthens the connection between the half-axle housing 2 and the transmission device, improving the overall load-bearing capacity. During the daily operation of the forklift, the internal... The engagement of the connecting block 8 and the inner rail 9 continuously ensures the stability of power transmission between the half-bridge housing 2 and the transmission device, preventing power transmission interruption. The engagement of the outer connecting block 11 and the outer rail 10 restricts the longitudinal displacement of the half-bridge housing 2, while the reinforcing arm 12 continuously distributes the load. The I-shaped and convex shapes maintain the tightness of each connection part, preventing loosening due to vibration. If the half-bridge housing 2 needs to be disassembled later, simply release the reinforcing arm 12 from the support ring 6, push the outer connecting block 11 back along the outer rail 10, and then pull the half-bridge housing 2 outward to disengage the inner connecting block 8 from the inner rail 9. Compared with the bolt-fixed method in the prior art, the operation is more convenient, reducing disassembly and assembly time and component wear.

[0030] Operating principle and advantages: When applying this device, the first step is installation. The transmission device body 1 is placed in the preset installation position. The main shaft 3 inside the transmission device body 1 serves as the core component for power transmission, connecting to the forklift transmission system to ensure stable power transmission to subsequent structures. A connecting frame 4 is provided on the top of the main shaft 3, allowing it to connect with other forklift structures, thereby improving the overall stability of the transmission device body 1 after installation and preventing displacement during subsequent operations. Support arms 5 are provided on the upper ends of both sides of the transmission device body 1, providing a stable mounting carrier for the installation mechanism 7 and ensuring its proper fixing function. A support ring 6 is provided on the top of the support arm 5, fitted onto the outside of the main shaft 3. The main shaft 3 is rotatably connected to the inside of the support ring 6, limiting the radial displacement of the main shaft 3 and ensuring its stability during rotation, preventing positional displacement due to vibration that could affect power transmission.

[0031] Then, align the two half-bridge housings 2 with both sides of the transmission device body 1. Internal connecting blocks 8 are provided at both ends of the transmission device, and internal connecting rails 9 are provided at both ends of the inner side of the half-bridge housing 2. By setting the internal connecting blocks 8 and the internal connecting rails 9, the internal connecting blocks 8 can be inserted into the inner connecting rails 9, thereby achieving initial positioning of the half-bridge housing 2 and the transmission device body 1, preventing lateral displacement of the half-bridge housing 2 during subsequent installation. The internal connecting blocks 8 are I-shaped when viewed from above, and the internal connecting rails 9 are U-shaped when viewed from above. This shape design further enhances the tightness of their fit, ensuring a more reliable initial positioning effect. Next, an external connecting rail 10 is provided in the middle of the outer side of the half-bridge housing 2, and an external connecting block 11 is provided inside the external connecting rail 10. By setting the external connecting rail 10 and the external connecting block 11, the external connecting rail 10 is positioned so that the half-bridge housing 2 is properly positioned. The connecting block 11 can slide along the outer rail 10 to a designated position; the top of the outer connecting block 11 is provided with a reinforcing arm 12, the top of the reinforcing arm 12 is fixedly connected to the outside of the support ring 6. By providing the reinforcing arm 12, it can connect the half-bridge housing 2 and the support ring 6, thereby enhancing the connection strength between the half-bridge housing 2 and the support ring 6, dispersing the force borne by the half-bridge housing 2, and avoiding excessive local stress on the half-bridge housing 2, which could lead to structural damage. Then, the half-bridge housing 2 is fixed by the installation mechanism 7. The lower ends of both sides of the support arm 5 are provided with installation rails 71. By providing the installation rails 71, the limit module 72 is provided with installation and operating space, ensuring that the limit module 72 can move within a specified range; the limit module 72 is provided with a lead screw 721, which is rotatably connected to the support ring 6. Inside the mounting rail 71, the threads at both ends of the lead screw 721 rotate in opposite directions. This threaded structure allows the sliders 723 at both ends to slide synchronously in opposite directions along the mounting rail 71 when the lead screw 721 is rotated. Limiting arms 724 are provided on the outer side of the sliders 723, and slots 722 are provided on both sides of the half-bridge housing 2. By setting the limiting arms 724 and the slots 722, the limiting arms 724 can move with the sliders 723 and insert into the slots 722, thus fixing the half-bridge housing 2. The mounting mechanism 7 is also equipped with an adjustment module 73, which includes a fixing plate 731 and an adjustment handle 732. The fixing plate 731 is fixed to one end of the mounting rail 71, and the inner side of the adjustment handle 732 is connected to the lead screw 723. The outer end of the rod 721 is connected to an adjustment handle 732. By rotating the adjustment handle 732, the operator can drive the lead screw 721 to rotate without the need for special tools, thus simplifying the operation. A locking screw 733 is provided on one side of the adjustment handle 732. The outer side of the fixed plate 731 has a locking hole 734. The locking holes 734 are arranged in a ring at equal intervals. By setting the locking screw 733 and the locking hole 734, turning the locking screw 733 so that its end is inserted into the locking hole 734 can restrict the rotation of the adjustment handle 732, thereby preventing the lead screw 721 from rotating due to vibration and causing the limiting arm 724 to loosen. This ensures the stable fixed state of the half-bridge housing 2. The entire installation process does not rely on a large number of bolts, greatly reducing the installation steps and improving the installation efficiency.

[0032] During normal use, when the forklift is running, the main shaft 3 transmits power to the half-axle housing 2 through the transmission device body 1, driving the forklift. During this stage, the continuous cooperation of the inner connecting block 8 and the inner connecting rail 9 ensures a stable connection between the half-axle housing 2 and the transmission device body 1 during power transmission, preventing power interruption from affecting forklift operation. The synergistic effect of the reinforcing arm 12, the outer connecting block 11, and the outer connecting rail 10 disperses the load on the half-axle housing 2, reducing the risk of deformation due to concentrated stress. The limiting arm 724 of the limiting module 72 is continuously inserted into the slot 722. The support ring 6 and the support arm 5 work together to prevent the half-bridge housing 2 from detaching from the transmission device body 1 during stress, ensuring structural safety. The support ring 6 and the support arm 5 work together to ensure the continuous rotational stability of the main shaft 3, preventing the main shaft 3 from shifting and affecting power transmission efficiency. Through the coordinated work of all components, the overall structure enhances the load-bearing capacity and operational stability of the device, enabling it to meet the needs of heavy-duty forklifts and adapt to high-intensity operating scenarios. When disassembly and maintenance are required, first operate the locking screw 733 on the adjusting handle 732. By loosening the locking screw 733, its end is pulled out of the locking hole 734. The rotation restriction on the adjusting handle 732 is released; then the adjusting handle 732 is rotated in the opposite direction, which drives the lead screw 721 to rotate in the opposite direction. Because the threads at both ends of the lead screw 721 turn in opposite directions, the rotation of the lead screw 721 drives the sliders 723 at both ends to move inward. The sliders 723 simultaneously drive the limiting arm 724 to be pulled out of the slot 722, thereby releasing the fixation restriction on the half-bridge housing 2; then the external locking block 11 is pushed to slide along the external rail 10, so that the reinforcing arm 12 is separated from the support ring 6, breaking the connection between the half-bridge housing 2 and the support ring 6; then the half-bridge housing 2 is pulled outward, so that the inner The connecting block 8 can be pulled out from the inner connecting rail 9, and the half-bridge housings 2 on both sides can be easily removed, making it convenient to inspect and maintain a single half-bridge housing 2. If it is necessary to disassemble the entire transmission device body 1, it is only necessary to remove the connection between the connecting frame 4 and other structures of the forklift, and the entire transmission device body 1 can be moved away without additional disassembly of complex parts, simplifying the overall disassembly process. This technical solution effectively solves the problems of existing technologies that rely on bolt connections, can only disassemble one side of the axle housing, and are cumbersome to disassemble as a whole, by reducing operation steps and time consumption, while reducing the risk of component wear caused by repeated disassembly of bolts, and improving maintenance convenience.

[0033] It is evident that the various structures of this technical solution demonstrate significant advantages through synergistic action: the I-shaped design of the inner connecting block 8 and the convex design of the inner connecting rail 9 and the outer connecting rail 10 enhance the stability of the fit between the components, prevent loosening of the connections, thereby extending the service life of the device and reducing failures caused by loose components; the adjustment handle 732 allows for operation without special tools, further improving the ease of disassembly and assembly and reducing the difficulty of operation for operators; the cooperation between the locking screw 733 and the locking hole 734 ensures reliable limit status, preventing the adjustment handle 732 from rotating and the lead screw 721 from rotating due to vibration during forklift operation, thereby preventing the limit arm 724 from loosening and affecting structural stability. These designs not only specifically address the shortcomings of existing technologies but also further enhance the structural strength and operational flexibility of the device, making it more adaptable to the actual maintenance and use needs of heavy-duty forklifts and suitable for disassembly and operation requirements in different scenarios.

[0034] The scope of protection of this application does not involve improvements to the electronic components of the device or equipment. Therefore, the working principles of each electronic component are not described in detail here. The electronic components in this application are all conventional electronic components used in the prior art. They are all conventional technical means in the prior art, and the application of the prior art is very mature. Therefore, they will not be elaborated here.
