Abstract
Description
Technical Field
[0001] This invention relates to the field of truck suspension system technology, and more specifically to a truck front suspension bracket that is easy to install and its installation method. Background Technology
[0002] Both the front and rear suspension brackets are core components of the truck suspension system. Their main functions are to connect the truck cab to the frame, support the weight of the cab, and work with the airbags to suspend and buffer the cab, reducing the impact of road bumps on the cab during vehicle operation and improving driving comfort. At the same time, they provide installation support for components such as cylinders and airbags, ensuring the normal operation of related truck components. Their ease of installation, structural stability, and performance directly affect the truck's driving experience, maintenance efficiency, and service life.
[0003] In existing technologies, truck front and rear suspension supports are mostly separate, independent designs with unreasonable structural designs, failing to achieve synergistic effects and fully utilize the four airbags in the cab, making it difficult to achieve true four-point suspension. Specifically, existing truck front suspension supports are typically made of thin sheet metal, resulting in insufficient structural strength and susceptibility to deformation and damage. The upper holes for accommodating the hydraulic cylinders are often ordinary round holes without anti-noise structures, easily generating noise during cylinder floating. Furthermore, there is no dedicated anti-interference structure, or the anti-interference structure is poorly designed, and the support's bending angle is inappropriate, easily causing friction and wear with the truck's intercooler pipes. Additionally, the existing front suspension supports have short sliding rails, failing to effectively improve cab suspension comfort, and limiting the cab's lifting angle. During engine lifting and maintenance, and the disassembly and cleaning of the radiator and intercooler, the support needs to be disassembled, making the operation cumbersome and affecting maintenance efficiency.
[0004] Existing truck rear suspension brackets also suffer from insufficient structural strength. The sheet metal used is too thin, making it unsuitable for various working conditions and installation requirements. Furthermore, the diameter of the connection holes is unreasonable, resulting in poor compatibility with the mounting holes of existing truck components and inconvenient installation. Additionally, the rear suspension bracket's design is flawed, failing to alter the stress point and installation angle of the rear airbag. This causes the airbag to be mostly positioned at an angle, unable to bear force vertically, thus failing to fully utilize its original performance. Consequently, the cab's suspension comfort is poor, making it difficult to meet the needs of truck drivers, repair shops, and parts suppliers.
[0005] In addition, the existing methods for installing truck front and rear suspension brackets are quite cumbersome. The installation process often requires modification of existing truck parts, which not only increases the difficulty and cost of installation, but may also damage the original structure of the truck and affect the overall safety of the truck. At the same time, the lack of standardized debugging procedures after installation can easily lead to problems such as poor cylinder floating, abnormal noise, wear of intercooler pipes, and abnormal stress on the rear suspension airbag, resulting in a decline in the performance of the bracket and an inability to operate stably for a long time.
[0006] To address the shortcomings of the existing technology, this invention provides an easy-to-install truck front suspension bracket and its installation method, thereby solving the problems in the prior art, improving the structural stability, ease of installation, and performance of the bracket, while simplifying the installation process and reducing installation costs. Summary of the Invention
[0007] The purpose of this invention is to overcome the defects in the prior art and provide a truck front suspension bracket and its installation method that are easy to install. This invention solves the problems of inconvenient installation, insufficient structural strength, easy abnormal noise, easy wear of intercooler pipes, limited cab lifting, inability of rear suspension airbags to bear force properly, and poor four-point suspension effect of existing brackets. At the same time, it solves the problems of cumbersome installation methods, the need to modify the original truck structure, and non-standard debugging, thereby improving the performance, ease of installation, and installation quality.
[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a truck front suspension bracket that is easy to install, comprising a front suspension bracket body and a rear suspension bracket body, wherein the front suspension bracket body and the rear suspension bracket body cooperate to adapt to the existing truck cab and four airbag installation structure, and jointly realize the four-point suspension of the truck cab; the bottom of the front suspension bracket body is provided with a flip rod connecting hole for screws to be threaded and fixed with the front suspension flip rod hole; the middle of the front suspension bracket body is provided with a support shaft pin connecting hole for threading and fixing with the front suspension support shaft pin; the upper part of the front suspension bracket body is provided with a cylinder sliding hole, i.e., a cylinder sliding groove, wherein the cylinder sliding hole is a sliding track structure for accommodating the cylinder and allowing it to float up and down; The rear suspension bracket body is provided with an airbag bottom connection hole, a rear suspension support connection hole, and a rear suspension lower hole connection hole. The airbag bottom connection hole is used for through-mounting with the bottom of the airbag, the rear suspension support connection hole is used for through-mounting with the original airbag position of the rear suspension support, and the rear suspension lower hole connection hole is used for connection with the lower hole position of the rear suspension. The design of the rear suspension bracket body can change the stress point and installation position of the rear suspension airbag, so that the rear airbag is in a straight up-down stress state, giving full play to the original buffering performance of the airbag. The front suspension bracket body is provided with an anti-interference slide rail communicating with the cylinder sliding hole. The anti-interference slide rail and the cylinder sliding hole work together to realize the anti-interference and anti-noise floating of the cylinder. Both the front suspension bracket body and the rear suspension bracket body are made of thickened manganese plate to improve structural strength and adaptability.
[0009] Furthermore, the front suspension bracket body is integrally molded from 6mm thick manganese plate neutral sheet, forming a thickened and heavy-duty structure. The manganese plate neutral sheet undergoes rust-proofing treatment, which improves the corrosion resistance, structural strength, and stability of the front suspension bracket body, extending its service life and preventing deformation and damage during use. The integral molding structure reduces splicing gaps, avoids stress concentration, and further enhances the bracket's load-bearing capacity and structural stability, extending its service life by more than 30% compared to existing spliced front suspension brackets.
[0010] Furthermore, the anti-interference slide rail is lengthened to 9cm, and by optimizing the bending angle of the front suspension bracket body, a preset safe distance is maintained between the anti-interference slide rail and the intercooler pipe, completely avoiding wear on the intercooler pipe. Simultaneously, it allows the cab to be raised to its maximum angle, enabling engine lifting and maintenance, as well as water tank and intercooler disassembly and cleaning operations, without disassembling the bracket. This significantly improves maintenance efficiency and reduces the workload of maintenance personnel. The preset safe distance is 5-8mm, which both prevents intercooler pipe wear and ensures the structural compactness of the bracket, without occupying additional installation space.
[0011] Furthermore, the slide rail structure of the cylinder sliding hole features an upgraded anti-noise design. The inner wall of the slide rail is equipped with a smooth, wear-resistant layer made of polytetrafluoroethylene (PTFE). This layer reduces noise interference during cylinder floating, lowers the coefficient of friction between the cylinder and the inner wall of the slide rail, allowing the cylinder to move freely up and down within the slide rail groove. It also provides dual protection against interference and noise during the up-and-down movement of the cab, further enhancing driving comfort. Simultaneously, the smooth, wear-resistant layer improves the wear resistance of the slide rail, extending the service life of the cylinder and its support.
[0012] Furthermore, the rear suspension bracket body is integrally formed from a 10mm thick manganese plate. The diameter of the connecting holes at the bottom of the airbag, the rear suspension support, and the lower rear suspension support is 14mm, precisely matching the mounting holes and connectors of existing truck components. This allows for direct installation without modifying existing truck parts, improving installation convenience and compatibility. Compared to the plates used in existing rear suspension brackets, the 10mm thick manganese plate offers over 50% increased structural strength, enabling it to adapt to installation and usage requirements under various conditions such as high and low temperatures and bumpy roads, and is less prone to deformation and damage.
[0013] Furthermore, the overall appearance of the rear suspension bracket body is optimized to meet the installation requirements of various working conditions. Its curvature precisely matches the existing truck rear suspension installation space, enabling smooth installation under various conditions such as high and low temperatures and bumpy roads. The structure also features uniform stress distribution, avoiding damage caused by localized stress concentration. Through this optimized design, the installation efficiency of the rear suspension bracket body is improved by more than 40% compared to existing rear suspension brackets, and its stability after installation is significantly enhanced.
[0014] Furthermore, the front suspension bracket body is adaptable to existing truck single-bracket or double-bracket installation methods. Regardless of the installation method, it can work in conjunction with the rear suspension bracket body to enable all four airbags in the truck cab to operate simultaneously, achieving true four-point suspension and improving cab comfort by approximately two times compared to existing brackets. This adaptability design expands the scope of application of the invention, meeting the installation needs of different truck models and structures, eliminating the need for separately designed brackets for different trucks, and reducing production costs.
[0015] The present invention also provides an easy-to-install truck front suspension bracket installation method, based on any of the above-described easy-to-install truck front suspension brackets, the installation method comprising the following steps: Step 1: Positioning and installing the front suspension bracket body. Align the flip rod connection hole at the bottom of the front suspension bracket body with the corresponding hole of the existing truck front suspension flip rod, insert the adapter screw and tighten it to fix it, thus completing the positioning of the bottom of the front suspension bracket body; then align the support pin connection hole in the middle of the front suspension bracket body with the pin of the existing truck front suspension support, and insert the pin into the support pin connection hole to complete the positioning and installation of the middle of the front suspension bracket body. Step 2: Hydraulic cylinder installation. Place the existing truck hydraulic cylinder into the hydraulic cylinder sliding hole on the upper part of the front suspension bracket body, adjust the position of the hydraulic cylinder to ensure that the hydraulic cylinder can float freely up and down along the slide of the hydraulic cylinder sliding hole, and that the hydraulic cylinder does not interfere with the anti-interference slide. Step 3: Positioning and installing the rear suspension bracket body. Align the bottom connection hole of the airbag on the rear suspension bracket body with the bottom of the existing truck airbag, align the connection hole of the rear suspension support with the original airbag position of the existing truck rear suspension support, and align the lower hole connection hole of the rear suspension with the position of the lower hole of the existing truck rear suspension. Insert the matching connectors and tighten them to fix them. This completes the overall installation of the rear suspension bracket body. Step 4: Debugging and inspection. Start the truck cab floating test and check whether the hydraulic cylinder floats smoothly along the hydraulic cylinder sliding hole without obvious abnormal noise; check whether there is any contact risk between the anti-interference slide and the intercooler pipe to ensure that there is no friction or wear; check whether the rear suspension airbag is in a straight up and down force state; check the connection stability between the front suspension bracket body and the rear suspension bracket body to ensure that there is no looseness. Step 5: Optimization and Adjustment. If abnormal noise is found in the hydraulic cylinder floating mechanism during Step 4, grind and lubricate the inner wall of the hydraulic cylinder sliding hole until the abnormal noise is eliminated. If a potential contact problem is found between the anti-interference slide and the intercooler pipe, fine-tune the installation angle of the front suspension bracket body. If the rear suspension airbag is not in a straight up-down force state, fine-tune the installation position of the rear suspension bracket body. If the bracket connection is loose, tighten the corresponding connecting parts until the usage requirements are met, and complete the overall installation.
[0016] Furthermore, the screws used in step 1 are precisely matched with the connecting holes of the tilting rod and the front suspension tilting rod, and the axle pins used in step 1 are precisely matched with the connecting holes of the support axle pins and the front suspension support axle pins; the connectors used in step 3 are precisely matched with the connecting holes at the bottom of the airbag, the connecting holes of the rear suspension support, the connecting holes of the lower hole of the rear suspension, and the corresponding truck installation parts. During the installation process, there is no need to cut or drill existing truck parts, which avoids damage to the original truck structure, reduces installation difficulty and cost, and ensures the overall safety of the truck.
[0017] Furthermore, in step 4, during the cab floating test, the connection stability between the front suspension bracket body and the rear suspension bracket body is checked to ensure there is no looseness; in step 5, after the fine adjustment is completed, the floating test is performed again until the cylinder floats smoothly, there is no abnormal noise, the intercooler pipe is unworn, the rear suspension airbag is under normal force, and the cab can be raised to the maximum angle to ensure the bracket installation quality and ensure the long-term stable operation of the bracket.
[0018] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages compared with the prior art: A. Easy and efficient installation without modifying existing parts: The flip rod connection hole and support pin connection hole of the front suspension bracket body are precisely matched with the existing truck front suspension flip rod and front suspension support.

During installation, it can be directly connected and fixed without cutting, drilling or other modifications to existing truck parts. At the same time, the supporting installation method is standardized and orderly, and the installation efficiency is improved by more than 40% compared with the existing bracket.
[0019] B. Wide adaptability and strong practicality: The front suspension bracket body can be adapted to the existing single bracket and double bracket installation forms of trucks.

[0021] D. Scientific and reasonable structural design, uniform and stable stress distribution: The front suspension bracket body is integrally molded to reduce splicing gaps and avoid stress concentration; the rear suspension bracket body has an optimized curvature that precisely matches the installation space of the truck's rear suspension, resulting in uniform structural stress distribution, avoiding damage caused by local stress concentration, and ensuring long-term stable operation of the bracket.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0028] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.
[0029] Unless otherwise defined, 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; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0030] like Figure 1-4 As shown, the present invention provides a truck front suspension bracket that is easy to install, including a front suspension bracket body 1 and a rear suspension bracket body 2. The front suspension bracket body 1 and the rear suspension bracket body 2 work together to achieve four-point suspension of the truck cab, improving driving comfort and ease of installation. At the same time, it is compatible with existing truck structures, requiring no modification to existing parts and reducing installation costs.
[0031] The front suspension bracket body 1 is made of 6mm thick manganese plate neutral sheet metal, forming a thickened and heavy-duty structure. The manganese plate neutral sheet metal is galvanized for rust prevention, which effectively improves the corrosion resistance, structural strength, and stability of the front suspension bracket body 1, preventing deformation and damage during use. Compared with existing spliced front suspension brackets, its service life is extended by more than 30%. The one-piece molding structure reduces splicing gaps, avoids stress concentration, and further improves the bracket's load-bearing capacity and structural stability, making it suitable for various working conditions.
[0032] The bottom of the front suspension bracket body 1 is provided with a flip rod connection hole 11. During installation, the flip rod connection hole 11 is aligned with the corresponding hole of the existing truck front suspension flip rod, and the adapter screws are tightened to fix the bottom of the front suspension bracket body 1. The middle of the front suspension bracket body 1 is provided with a support axle pin connection hole 12. This hole is aligned with the axle pin of the existing truck front suspension support, and the axle pin is inserted into the support axle pin connection hole 12 to complete the positioning and installation of the middle of the front suspension bracket body 1. The overall installation does not require modification of existing truck parts, making the operation convenient and the installation efficiency high.
[0033] The upper part of the front suspension bracket body 1 is provided with a cylinder sliding hole 13, which is the cylinder sliding groove. It adopts a sliding track structure to accommodate the existing truck cylinder and allow the cylinder to float freely up and down. The sliding track structure of the cylinder sliding hole 13 is designed to prevent abnormal noise. The inner wall of the sliding track is provided with a smooth and wear-resistant layer made of polytetrafluoroethylene, which can reduce friction and abnormal noise between the cylinder and the inner wall of the sliding track during the floating process and reduce the coefficient of friction. When the cab floats up and down, it can not only ensure the normal stroke of the cylinder, but also play a dual role of preventing interference and abnormal noise, further improving driving comfort. At the same time, the smooth and wear-resistant layer can also improve the wear resistance of the sliding track and extend the service life of the cylinder and bracket.
[0034] In addition, an anti-interference slide is integrally set on the front suspension bracket body 1. This anti-interference slide is connected to the cylinder sliding hole 13 and is extended to 9cm, which can further improve the comfort performance of the cab suspension. At the same time, by optimizing the bending angle of the front suspension bracket body 1, the anti-interference slide maintains a preset safety distance of 5-8mm from the intercooler pipe, which completely avoids friction and wear between the bracket body and the existing truck intercooler pipe. It can also raise the cab to the maximum angle. When performing engine hoisting and maintenance, and disassembling and cleaning the water tank and intercooler, there is no need to disassemble this bracket, which greatly improves the convenience and efficiency of maintenance operations and reduces the labor intensity of maintenance personnel.
[0035] The front suspension bracket body 1 can be adapted to the single-bracket or double-bracket installation of existing trucks. Regardless of the installation method, it can work with the rear suspension bracket body 2 to enable the four airbags in the truck cab to work simultaneously, achieving true four-point suspension. This improves the comfort of the cab by about 2 times compared to existing brackets. The adaptability design expands the scope of application of this invention, meeting the installation needs of different models and structures of trucks. It eliminates the need to design brackets separately for different trucks, reducing production costs.
[0036] The rear suspension bracket body 2 is integrally molded from a 10mm thick manganese plate, forming a thickened and reinforced structure. Compared to the plates used in existing rear suspension brackets, the 10mm thick manganese plate increases structural strength by more than 50%, making it suitable for installation and use under various conditions such as high and low temperatures and bumpy roads, and less prone to deformation and damage. The rear suspension bracket body 2 has three connection holes: an airbag bottom connection hole 21, a rear suspension support connection hole 22, and a rear suspension lower hole connection hole 23. The diameter of all three connection holes is set to 14mm, which is compatible with the corresponding mounting holes and connectors of the existing truck airbag bottom, the original airbag position of the rear suspension support, and the lower hole of the rear suspension. During installation, there is no need to modify existing truck parts; they can be directly threaded together for installation. The installation is convenient and efficient, with an installation efficiency that is more than 40% higher than that of existing rear suspension brackets.
[0037] The overall appearance of the rear suspension bracket body 2 has been specially optimized, with its curvature precisely matching the existing truck rear suspension installation space. This allows for smooth installation under various working conditions, such as high and low temperatures and bumpy roads, and ensures uniform stress distribution, avoiding damage caused by localized stress concentration. At the same time, the design changes the stress point position and installation angle of the existing rear suspension airbag, transforming it from an angled position to a vertically aligned position. This fully utilizes the original cushioning performance of the airbag. Combined with the function of the front suspension bracket body 1, it enables all four airbags in the truck cab to work simultaneously, achieving true four-point suspension and significantly improving driving comfort, thus solving the problem of poor comfort caused by existing brackets.
[0038] The present invention also provides an easy-to-install truck front suspension bracket installation method. Based on the above-mentioned easy-to-install truck front suspension bracket, the specific installation steps are as follows: Step 1: Positioning and installing the front suspension bracket body 1. Align the flip rod connection hole 11 at the bottom of the front suspension bracket body 1 with the corresponding hole of the existing truck front suspension flip rod, insert the matching screw and tighten it to fix it, thus completing the positioning of the bottom of the front suspension bracket body 1; then align the support pin connection hole 12 in the middle of the front suspension bracket body 1 with the axle pin of the existing truck front suspension support, and insert the axle pin into the support pin connection hole 12 to complete the positioning and installation of the middle of the front suspension bracket body 1; the screws used are precisely matched with the flip rod connection hole 11 and the front suspension flip rod hole, and the axle pins used are precisely matched with the support pin connection hole 12 and the front suspension support axle pin hole, without the need to modify the existing parts.
[0039] Step 2: Hydraulic cylinder installation. Place the existing truck hydraulic cylinder into the hydraulic cylinder sliding hole 13 on the upper part of the front suspension bracket body 1. Adjust the position of the hydraulic cylinder to ensure that the hydraulic cylinder can float freely up and down along the slide of the hydraulic cylinder sliding hole 13, and that the hydraulic cylinder does not interfere with the anti-interference slide, so as to avoid friction between the hydraulic cylinder and the anti-interference slide during the floating process, which would cause abnormal noise.
[0040] Step 3: Position and install the rear suspension bracket body 2. Align the airbag bottom connection hole 21 on the rear suspension bracket body 2 with the bottom of the existing truck airbag, align the rear suspension support connection hole 22 with the original airbag position of the existing truck rear suspension support, and align the rear suspension lower hole connection hole 23 with the position of the existing truck rear suspension lower hole. Insert the matching connectors and tighten them to fix them. This completes the overall installation of the rear suspension bracket body 2. The connectors used are precisely matched with the three connection holes and the corresponding truck installation parts, without the need to modify the existing truck parts.
[0041] Step 4: Debugging and inspection. Start the truck cab floating test and check whether the hydraulic cylinder floats smoothly along the hydraulic cylinder sliding hole 13 without obvious abnormal noise; check whether there is any contact risk between the anti-interference slide and the intercooler pipe to ensure that there is no friction or wear; check whether the rear suspension airbag is in a straight up and down force state; check the connection stability between the front suspension bracket body 1 and the rear suspension bracket body 2 to ensure that there is no looseness, and comprehensively check for possible problems during the installation process to ensure the performance of the bracket.
[0042] Step 5: Optimization and Adjustment. If abnormal noise is found in the cylinder floating process in Step 4, polish and lubricate the inner wall of the cylinder sliding hole 13 slide until the abnormal noise is eliminated. If a potential contact hazard is found between the anti-interference slide and the intercooler pipe, fine-tune the installation angle of the front suspension bracket body 1 to ensure a safe distance of 5-8mm between them. If the rear suspension airbag is not in a straight up-down force state, fine-tune the installation position of the rear suspension bracket body 2. If the bracket connection is loose, tighten the corresponding connecting parts. After fine-tuning, perform the floating test again until the cylinder floats smoothly, there is no abnormal noise, the intercooler pipe is unworn, the rear suspension airbag is under normal force, and the cab can be raised to the maximum angle to complete the overall installation.
[0043] In this embodiment, the front suspension bracket body and the rear suspension bracket body are designed collaboratively. This retains the installation compatibility of the existing brackets while solving many defects in the prior art through structural optimization. The front suspension bracket body is made of thickened manganese plate in one piece, with anti-interference extended slide rails and anti-noise cylinder sliding holes to avoid intercooler pipe wear, reduce noise, and improve comfort performance and structural stability. The rear suspension bracket body is also made of thickened manganese plate in one piece, and the optimized shape design allows the rear suspension airbag to bear force vertically, giving full play to the airbag performance. The two work together to achieve true four-point suspension of the cab, greatly improving driving comfort.
[0044] Specifically, this invention designs the front suspension bracket body and the rear suspension bracket body in a coordinated manner. It retains the installation compatibility of the existing brackets while solving many defects in the prior art through structural optimization. The front suspension bracket body is made of thickened manganese plate in one piece, and is equipped with anti-interference extended slide rails and anti-noise cylinder sliding holes to avoid intercooler pipe wear, reduce abnormal noise, and improve comfort performance and structural stability. The rear suspension bracket body is also made of thickened manganese plate in one piece, and the optimized shape design allows the rear suspension airbag to bear force directly up and down, giving full play to the airbag performance. The two work together to achieve true four-point suspension of the cab, greatly improving driving comfort.
[0045] Meanwhile, the installation method provided by this invention is standardized and convenient, requiring no modification to existing truck parts, and has high installation efficiency. Through standardized debugging and optimization adjustment steps, the installation quality of the bracket is ensured, avoiding various malfunctions after installation and guaranteeing the long-term stable operation of the bracket. This invention has strong adaptability, can be adapted to single and double bracket installation forms, has a wide range of applications, reasonable structural design, and strong practicality, and can meet the needs of truck drivers, repair shops and parts suppliers, and has good market application prospects.
[0046] Based on the above specific implementation methods, combined with existing truck suspension systems and related components, this device can be adapted to different installation forms and various working conditions in practical applications. The following details its different usage scenarios, the usage status of each structure, as well as the effective connection and installation linkage details with existing technology devices, clarifying the collaborative working logic of each component.
[0047] Scenario 1: Single-frame installation (compatible with existing single-frame trucks) This design is compatible with existing trucks using a single-bracket mounting system. Installation requires no modification to the truck's original suspension structure; simply connect the device to the existing truck components for rapid adaptation. During installation, first precisely align the flip-rod connection hole 11 at the bottom of the front suspension bracket body 1 with the corresponding hole on the existing truck's front suspension flip-rod. Insert the existing screws that fit the hole and tighten them to secure the bottom of the front suspension bracket body 1, ensuring a firm and secure connection. Next, align the support pin connection hole 12 in the middle of the front suspension bracket body 1 with the existing truck's front suspension support pin. Insert the existing pin into the support pin connection hole 12 to complete the positioning and installation of the middle part of the front suspension bracket body 1. At this point, the front suspension bracket body 1 is vertically fixed to the truck's front suspension. The thickened and heavy-duty one-piece molded structure fits the existing installation space, ensuring even stress distribution. Subsequently, the existing truck hydraulic cylinder is placed in the hydraulic cylinder sliding hole 13 on the upper part of the front suspension bracket body 1, and the position of the hydraulic cylinder is adjusted to ensure that the hydraulic cylinder can float freely up and down along the slide of the hydraulic cylinder sliding hole 13, and that the hydraulic cylinder does not interfere with the anti-interference slide on the front suspension bracket body 1. The smooth wear-resistant layer on the inner wall of the hydraulic cylinder sliding hole 13 fits with the outer wall of the hydraulic cylinder, providing noise prevention and wear resistance for subsequent floating.
[0048] The installation of the rear suspension bracket body 2 is carried out simultaneously. The airbag bottom connection hole 21 on the rear suspension bracket body 2 is aligned with the mounting hole position of the existing truck airbag bottom, and the existing adapter connector is inserted for through-and-fix, ensuring that the airbag bottom is tightly connected to the rear suspension bracket body 2. The rear suspension support connection hole 22 is aligned with the hole position of the original airbag position of the existing truck rear suspension support, and the existing adapter connector is also used for through-and-fix. The rear suspension lower hole connection hole 23 is aligned with the corresponding position of the existing truck rear suspension lower hole, and the through-and-fix is completed. At this time, the rear suspension bracket body 2 forms a stable connection with the existing rear suspension components through the three connection holes. Its optimized shape fits the existing truck rear suspension installation space, so that the original inclined rear suspension airbag becomes a straight up and down force state, fully activating the original cushioning performance of the airbag.
[0049] During use, the anti-interference slide of the front suspension bracket body 1 maintains a preset safety distance of 5-8mm from the existing truck intercooler pipe. Due to the optimized bending angle, even if the cab moves up and down, the anti-interference slide will not rub against the intercooler pipe. When the hydraulic cylinder moves up and down along the hydraulic cylinder sliding hole 13, the smooth wear-resistant layer effectively reduces friction noise. The anti-interference slide and the hydraulic cylinder sliding hole 13 work together to achieve anti-interference and noise-proof floating of the hydraulic cylinder. The front suspension bracket body 1 and the rear suspension bracket body 2 work together to drive the four airbags of the existing truck cab to work simultaneously, achieving true four-point suspension. The comfort performance of the cab is about twice that of the existing bracket. When it is necessary to lift and repair the engine, or disassemble and clean the water tank and intercooler, it is not necessary to disassemble the front suspension bracket body 1 and the rear suspension bracket body 2. The cab can be directly lifted to the maximum angle. Thanks to the extended design of the anti-interference slide, there is no interference from any parts during the lifting process, which greatly improves maintenance efficiency.
[0050] Scenario 2: Dual-bracket installation (compatible with existing dual-bracket structure trucks) This configuration is adapted to existing trucks using a dual-bracket mounting system. The installation logic is the same as for the single-bracket mounting configuration, with the key difference being the number of front suspension bracket bodies 1 installed. Other connection and linkage details remain unchanged in terms of compatibility with existing truck components. During installation, one front suspension bracket body 1 is installed on each side of the existing truck's front suspension. Each front suspension bracket body 1 is fixed by passing through the corresponding hole in the existing front suspension tilting rod via the tilting rod connecting hole 11, and by passing through the existing front suspension support pin via the support axle pin connecting hole 12, ensuring symmetrical installation and balanced force distribution of the two front suspension bracket bodies 1. The cylinder sliding holes 13 of the two front suspension bracket bodies 1 respectively accommodate the cylinders on both sides of the existing truck. Adjusting the cylinder positions ensures smooth and uninterrupted movement of the cylinders on both sides.
[0051] The rear suspension bracket body 2 still adopts single-sided or double-sided installation (adapted to the existing truck rear suspension structure). Its connection method and installation details with the existing rear suspension components are completely consistent with the single bracket case. That is, it is connected to the existing airbag bottom, rear suspension support, and rear suspension lower hole through the airbag bottom connection hole 21, rear suspension support connection hole 22, and rear suspension lower hole connection hole 23 to ensure that the rear suspension airbag maintains a straight up and down force state.
[0052] During use, the two front suspension bracket bodies 1 work together to further enhance the structural stability and load-bearing capacity of the front suspension. Their anti-interference tracks maintain a safe distance from the existing intercooler pipes to avoid wear. The two hydraulic cylinders float synchronously along the corresponding hydraulic cylinder sliding holes 13, resulting in a more uniform anti-noise effect. The cab's suspension stability is further improved compared to the single-bracket installation. The front suspension bracket bodies 1 (both sides) and the rear suspension bracket bodies 2 work together to still drive the four airbags to work simultaneously, achieving stable four-point suspension. This meets the load-bearing requirements of existing dual-bracket trucks while retaining the advantages of lifting the cab without disassembling the brackets and convenient maintenance. The rear suspension bracket body 2, made of 10mm thick manganese plate, and the front suspension bracket body 1, made of 6mm thick manganese plate, can withstand the additional force of the dual-bracket structure, preventing deformation and damage during use, and significantly extending the service life compared to existing brackets.
[0053] Scenario 3: Complex working conditions (suitable for existing trucks operating under complex conditions such as high and low temperatures and bumpy roads) This scenario focuses on trucks that operate under complex conditions such as high and low temperatures and bumpy roads. It describes the performance of each component of this device under extreme conditions and its stability in conjunction with existing truck parts. Existing supports for these trucks generally suffer from insufficient structural strength, easy deformation, loose installation, and noticeable noise. This device, through structural optimization, achieves a more stable connection with existing truck parts, adapting to the needs of complex operating conditions.
[0054] During installation, the connection between the front suspension bracket body 1 and the existing front suspension tilting bar and front suspension support, and the connection between the rear suspension bracket body 2 and the existing rear suspension components, all use existing high-strength connectors to ensure that the connection points do not loosen or shift when driving on bumpy roads. The 6mm thick manganese plate neutral sheet of the front suspension bracket body 1 is rust-proofed, and the 10mm thick manganese plate of the rear suspension bracket body 2 is integrally formed, which can adapt to high and low temperature conditions and will not cause the plate to become brittle or deformed due to temperature changes, thus meeting the usage requirements of existing trucks with complex working conditions.
[0055] During use, the impact from bumpy roads is transmitted through the existing truck frame to the front suspension bracket body 1 and the rear suspension bracket body 2. Since both are thickened and reinforced one-piece molded structures, the force is evenly distributed without local stress concentration, which can effectively buffer the impact and prevent the bracket from deforming and being damaged. The optimized shape of the rear suspension bracket body 2 allows the rear suspension airbag to bear the force vertically. Even under severe bumps, the airbag can fully play its buffering role. Combined with the hydraulic cylinder floating buffer of the front suspension bracket body 1, it further improves the suspension stability of the cab and reduces the impact of bumps on the driver.
[0056] Under high and low temperature conditions, the anti-interference slide rail of the front suspension bracket body 1, the smooth and wear-resistant layer of the cylinder sliding hole 13, and the connection hole structure of the rear suspension bracket body 2 will not experience performance degradation due to temperature changes. When the cylinder floats along the cylinder sliding hole 13, it can still maintain a noise-free state, and the safe distance between the anti-interference slide rail and the intercooler pipe remains stable, avoiding component wear caused by temperature deformation. At the same time, the optimized appearance of the rear suspension bracket body 2 can adapt to the installation space under complex working conditions. Even if the truck drives on bumpy roads for a long time, the connection between the rear suspension bracket body 2 and the existing rear suspension components will not loosen. The three connection holes always fit precisely with the existing components, ensuring that the rear suspension airbags maintain a straight up-and-down force state. The front suspension bracket body 1 and the rear suspension bracket body 2 work together to always drive the four airbags to work stably, ensuring driving comfort and safety.
[0057] In summary, regardless of the usage scenario, this device can achieve precise adaptation and stable connection with existing truck suspension systems and related components without requiring modification of existing truck parts, making installation convenient and efficient. Each structure performs its specific function during use. The tilting rod connection hole 11, support pin connection hole 12, cylinder sliding hole 13, and anti-interference slide of the front suspension bracket body 1 work in concert with the airbag bottom connection hole 21, rear suspension support connection hole 22, and rear suspension lower hole connection hole 23 of the rear suspension bracket body 2, forming a complete linkage system with existing truck components. This not only solves many pain points of existing brackets but also fully adapts to existing technical devices, achieving a stable structure, convenient use, and excellent comfort performance.

Therefore, the scope of protection of the present invention should be determined by the claims.
