Description

Technical Field

[0001] This application belongs to the field of automotive suspension system technology, and more specifically, relates to a split leaf spring pressure block and a vehicle. Background Technology

[0002] The leaf spring clamping block tightly connects multiple leaf springs into a whole using bolts and lugs, forming a dynamic support structure. When the vehicle is in motion, the leaf spring clamping block can tightly connect the frame and the axle, ensuring the transmission of longitudinal, lateral, and vertical forces, while guiding the wheel trajectory and preventing loss of vehicle control due to the lack of a guiding mechanism.

[0003] Due to the complex and relatively harsh operating conditions of heavy-duty vehicles, the thickness of the leaf spring assembly varies to adapt to different conditions, and the bolt hole spacing on the leaf spring pressure block also needs to be adjusted. Currently, the leaf spring pressure block is integrally cast, and the bolt hole spacing cannot be adjusted according to the leaf spring pressure block of different thicknesses, resulting in poor versatility. This requires the use of multiple different molds to cast multiple different leaf spring pressure blocks, which to some extent increases material costs and raises the production costs for automakers. Utility Model Content

[0004] The purpose of this application is to provide a split leaf spring pressure block and vehicle, which aims to solve the problems of poor versatility of leaf spring pressure blocks, the large variety of molds required, and the resulting high material and production costs.

[0005] To achieve the above objectives, the technical solution adopted in this application is: to provide a split-type leaf spring pressure block, including: a connecting block and four bolt mounting blocks symmetrically arranged in pairs on both sides of the connecting block, wherein the bolt mounting blocks are provided with bolt holes; the bolt mounting blocks and the connecting block are detachably assembled so that the hole spacing of the bolt holes between two bolt mounting blocks on the same side is adjustable.

[0006] The beneficial effects of the split-type leaf spring pressure block provided in this application are as follows: Compared with the prior art, the split-type leaf spring pressure block of this application, by detachably assembling the bolt mounting block and the connecting block, allows for flexible adjustment of the bolt hole spacing between the two bolt mounting blocks on the same side according to actual needs when the bolt hole spacing on the same side increases or decreases, greatly improving the versatility of the leaf spring pressure block. This split structure can better adapt to the usage requirements of vehicles under different operating conditions, providing a more reliable guarantee for the stable operation of vehicles.

[0007] Furthermore, the split-type leaf spring pressure block eliminates the need for multiple different molds and castings, reducing the variety and quantity of molds and thus lowering material costs. Simultaneously, this reduces production costs for automakers, improving production efficiency and economic benefits.

[0008] In conjunction with the first aspect, in one possible implementation, a concave-convex fitting connection structure is provided between the connecting block and the bolt mounting block; the concave-convex fitting connection structure includes a universal protrusion disposed on the side of the bolt mounting block, and an adapter groove that can be machined on the side of the connecting block according to the hole spacing of the bolt holes; the adapter groove adapts to the universal protrusion.

[0009] In the above technical solution, the four bolt mounting blocks are general-purpose parts that can be directly cast without any machining to change their basic shape. The connecting block, as a common part that connects the four bolt mounting blocks together, only requires four matching grooves to be machined on the side of the connecting block after casting, based on the different bolt hole spacing required between the two symmetrical bolt mounting blocks. This design allows for flexible adjustment of the bolt hole spacing according to assembly needs. Furthermore, this process is simple, easy to manufacture, requires no complex equipment or procedures, and simplifies assembly.

[0010] In conjunction with the first aspect, in one possible implementation, the universal protrusion is a dovetail tenon; the adapter groove is a dovetail groove that mates with the dovetail tenon.

[0011] The dovetail groove and dovetail tenon connection structure enables the connecting block and bolt mounting block to form a self-positioning. The dovetail tenon and dovetail groove have good stability, which can ensure that the connection between the components is firm and not easy to loosen or fall off, thereby improving the reliability of the entire structure.

[0012] In conjunction with the first aspect, in one possible implementation, the general protrusion is a T-shaped protrusion; the adapter groove is a T-shaped groove that mates with the T-shaped protrusion.

[0013] This connection structure, as an implementation method parallel to the dovetail groove design, also enables the connecting block and bolt mounting block to form a self-positioning mechanism. The fit of the T-shaped protrusion and T-groove has good stability, ensuring that the connection between components is firm and not easy to loosen or fall off, thereby improving the reliability of the entire structure.

[0014] In conjunction with the first aspect, in one possible implementation, the side of the bolt mounting block has a mating surface that conforms to the side of the connecting block, the mating surface being located on both sides of the universal protrusion.

[0015] In the above technical solution, by having the bolt mounting block's side surfaces separately positioned on both sides of the universal protrusion, the contact area between the bolt mounting block and the connecting block is increased. After the leaf spring pressure block is tightened with bolts to secure the leaf spring, the friction between the two is increased, greatly enhancing the connection stability between the bolt mounting block and the connecting block. This effectively reduces the possibility of loosening between the two during use, thereby ensuring that the entire structure remains stable under various working conditions and improving the reliability of equipment operation.

[0016] In conjunction with the first aspect, in one possible implementation, the bolt mounting block is provided with a mounting ramp for mounting bolts, and the bolt hole is provided on the mounting ramp; the upper surface of the connecting block is higher than the mounting ramp, and the lower surface of the connecting block is flush with the lower surface of the bolt mounting block.

[0017] The design of the above technical solution makes the connecting block between the bolt mounting blocks thicker than the bolt mounting blocks, thereby improving the structural strength of the leaf spring pressure block and ensuring the firmness of the compression of the leaf spring.

[0018] The lower surface of the connecting block is flush with the lower surface of the bolt mounting block, so that the lower surface of the leaf spring pressure block is pressed flat against the flat steel leaf spring, ensuring surface-to-surface contact between the leaf spring pressure block and the steel leaf spring, and improving the firmness and stability of the pressing.

[0019] In conjunction with the first aspect, in one possible implementation, the upper surface of the connecting block is a plane, and the upper surface of the universal protrusion is flush with the upper surface of the connecting block.

[0020] In conjunction with the first aspect, in one possible implementation, the upper surface of the connecting block is an arc-shaped curved surface, and the upper surface of the universal protrusion is an arc-shaped curved surface that connects to the upper surface of the connecting block.

[0021] The upper surface of the connecting block is designed as a flat surface or an arc-shaped surface, which are two structural forms of the connecting block. Based on the reinforcing effect of the connecting block protruding between the bolt mounting blocks, these two structural forms can be selected according to the space reserved around them. Under the premise of reducing costs and weight, both can maximize the bending section modulus of the leaf spring pressure block, which is beneficial to enhancing the bending deformation resistance of the leaf spring pressure block.

[0022] In conjunction with the first aspect, in one possible implementation, the lower surface of the connecting block is provided with a positioning pin hole.

[0023] During the installation of the leaf spring pressure block, the position of the connecting block can be accurately determined, allowing it to quickly and accurately align with the locating pins on the leaf spring, effectively improving installation efficiency and precision. The positioning function achieved through the cooperation of the locating pin holes and corresponding locating pins also reduces loosening or instability caused by positional deviations, greatly enhancing the stability and reliability of the entire structure.

[0024] Secondly, this application also provides a vehicle in which multiple leaf springs are connected into a whole using the aforementioned split leaf spring pressure block.

[0025] The vehicle provided in this application, by employing this split-type leaf spring pressure block, eliminates the need for multiple different molds and the casting of various leaf spring pressure blocks, thereby reducing the types and number of molds and lowering material costs. Simultaneously, this reduces the production costs for automakers, improving production efficiency and economic benefits. Attached Figure Description

[0028] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0029] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on that other element. It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0030] Regarding the left and right and side orientations used in this application, please refer to... Figure 1 , Figure 5 and Figure 7 The directions are marked in the middle.

[0031] Regarding the issue of varying thicknesses in the leaf spring assembly 3 as proposed in this application, and the need to adjust the bolt hole spacing 21 on the leaf spring pressure block, combined with... Figure 7 The installation of the leaf spring clamping block is explained as follows: Heavy-duty vehicle rear suspension systems generally employ a balanced suspension. A balance shaft assembly is located in the middle of the balanced suspension system. The leaf spring assembly 3 is positioned on the balance shaft housings 4 on both sides of the balance shaft assembly, with its ends freely resting on the sliding plate seats of the middle and rear axles, thus connecting the frame assembly and the axle assembly. As the main load-bearing component of heavy-duty vehicles, the leaf spring assembly 3 is tightened onto the balance shaft housings 4 by bolts that pass through the leaf spring clamping block.

[0032] Due to space constraints and the clamping stiffness requirements of the leaf spring assembly 3, the bolt holes 21 on the balance shaft housing 4 are arranged symmetrically on both sides with the center line of the balance shaft housing 4 as the reference and inclined towards the center line b of the balance shaft housing 4. Therefore, the bolts also need to be arranged in a fixed angle of inclination. The upper threaded end of the bolt passes through the corresponding hole of the leaf spring pressure block and is tightened and fixed by the nut. Therefore, the nut mounting surface of the leaf spring pressure block must also be set with a certain inclination angle, specifically forming an inverted V-shape with the nut mounting surface on the same side inclined towards the center line of the balance shaft housing 4. At the same time, the bolts arranged symmetrically on both sides form a V-shape.

[0033] At this point, along the vertical direction perpendicular to the leaf spring pressure block, the spacing between the symmetrical bolts on both sides is different at different positions along the vertical direction. This results in the following: when the thickness of the leaf spring assembly 3 (along the vertical direction) increases, the nut mounting surface rises, and the hole spacing of the symmetrical bolt holes 21 on both sides of the leaf spring pressure block becomes shorter; when the thickness of the leaf spring assembly 3 decreases, the nut mounting surface descends, and the hole spacing of the symmetrical bolt holes 21 on both sides of the leaf spring pressure block becomes longer (e.g., Figure 7In this case, the hole spacing L1 is smaller than the hole spacing L2. This results in the need to stock various types of leaf spring blocks, and correspondingly, various different molds are required. This not only increases material costs but also processing costs, and also requires more storage space for these molds and leaf spring blocks.

[0034] To address this problem, this application identifies and extracts the common structural features of leaf spring pressure blocks from individual characteristics. The design concept of the split leaf spring pressure block is as follows: the overall leaf spring pressure block is divided into five parts. The middle part without bolt holes 21 is the connecting block 1. Taking the center line of the balance shaft housing 4 as a reference, the parts that are inclined in different directions and have fixed hole spacing are divided into four parts, namely bolt mounting blocks 2. By adjusting the distance between two bolt mounting blocks 2 on the same side, the distance between the bolt holes 21 on the left and right sides and the center line of the balance shaft housing 4 can be adjusted, that is, the hole spacing of the bolt holes 21 between two bolt mounting blocks 2 on the same side can be adjusted.

[0035] Please refer to the following: Figures 1 to 6 The split-type leaf spring pressure block provided in this application will now be described. The split-type leaf spring pressure block includes: a connecting block 1 and four bolt mounting blocks 2 symmetrically arranged in pairs on both sides of the connecting block 1. The bolt mounting blocks 2 are provided with bolt holes 21. The bolt mounting blocks 2 and the connecting block 1 can be detachably assembled so that the hole spacing of the bolt holes 21 between two bolt mounting blocks 2 on the same side is adjustable.

[0036] The beneficial effects of the split-type leaf spring pressure block provided in this application are as follows: Compared with the prior art, this application, by detachably assembling the bolt mounting block 2 and the connecting block 1, allows for flexible adjustment of the bolt hole 21 distance between the two bolt mounting blocks 2 on the same side according to actual needs when the distance between the bolt holes 21 on the same side increases or decreases, greatly improving the versatility of the leaf spring pressure block. This split-type structure can better adapt to the usage requirements of vehicles under different working conditions, providing a more reliable guarantee for the stable operation of vehicles.

[0037] Furthermore, the split-type leaf spring pressure block eliminates the need for multiple different molds and castings, reducing the variety and quantity of molds and thus lowering material costs. Simultaneously, this reduces production costs for automakers, improving production efficiency and economic benefits.

[0038] The versatility of the split leaf spring pressure block lies in the fact that the bolt mounting block 2 can be used in any heavy-duty vehicle and can be applied to different working conditions without adjustment. In other words, the bolt mounting block 2 is a universal part because the suspension system of any heavy-duty vehicle uses bolts of the same specification to tightly connect the leaf spring pressure block to the multi-leaf spring assembly 3 into a whole. Therefore, the hole spacing of the two bolt holes 21 on each bolt mounting block 2 will not change, and the size of the bolt holes 21 will not change. This hole spacing and the size of the bolt holes 21 are determined by the bolt holes 21 on the balance shaft housing 4 of the suspension system. Only one mold needs to be configured for different bolt mounting blocks 2, and there is no need to prepare multiple molds. The hole spacing between the two bolt mounting blocks 2 can be adjusted simply by installing the two bolt mounting blocks 2 on the same side closer or further apart.

[0039] For different operating conditions, such as in some mining areas where the road surface is relatively flat, the selected heavy truck configuration can simply reduce the stiffness of the leaf spring assembly 3 and use a leaf spring assembly 3 with a smaller thickness, which can reduce operating costs. For mining areas with bumpy roads, a leaf spring assembly 3 with stronger anti-deformation performance and a thicker leaf spring assembly 3 is required for tightening, in order to reduce the vibration and impact caused by changes in the road surface.

[0040] In some embodiments, see Figures 1 to 6 As shown, a concave-convex fit connection structure is provided between the connecting block 1 and the bolt mounting block 2; the concave-convex fit connection structure includes a universal protrusion 23 provided on the side of the bolt mounting block 2, and an adapter groove 12 that can be machined on the side of the connecting block 1 according to the hole spacing of the bolt holes 21; the adapter groove 12 is adapted to the universal protrusion 23.

[0041] In the above technical solution, the four bolt mounting blocks 2 are general-purpose parts, which can be directly cast without any machining to change their basic shape. The connecting block 1, as a common part that connects the four bolt mounting blocks 2 together, only requires machining four matching grooves 12 on the side of the connecting block 1 after casting, based on the different bolt hole spacing 21 required between two symmetrical bolt mounting blocks 2. This design allows for flexible adjustment of the bolt hole spacing 21 according to assembly needs. Furthermore, this machining method is simple, easy to manufacture, requires no complex equipment or procedures, and simplifies assembly.

[0042] During assembly, simply align the universal protrusions 23 of the four bolt mounting blocks 2 with the adapter slots 12 on the connecting block 1 and insert them. Assembly is simple and convenient.

[0043] After the bolts are fastened to the leaf spring assembly 3, the contact surface between the connecting block 1 and the bolt mounting block 2 generates friction, which can clamp the connecting block 1 between the four bolt mounting blocks 2 on both sides.

[0044] In some embodiments, see Figures 1 to 6 As shown, the general protrusion 23 is a dovetail tenon; the adapter groove 12 is a dovetail groove that mates with the dovetail tenon. The dovetail groove and dovetail tenon connection structure allows the connecting block 1 and the bolt mounting block 2 to form a self-positioning system. The dovetail tenon and dovetail groove fit provides good stability, ensuring a firm connection between components, preventing loosening or detachment, thus improving the overall reliability of the structure. This connection method maintains a tight fit even under certain external forces, effectively reducing the risk of failure due to unstable connections. Moreover, this mortise and tenon structure using dovetail grooves and dovetail tenons is simple in structure, easy to assemble, and the processing of dovetail tenons and dovetail grooves is relatively convenient, allowing for standardized manufacturing processes, which helps improve production efficiency and reduce production costs.

[0045] At the same time, this fitting method has certain precision requirements, which enables the components to be precisely aligned during installation, helps to improve the overall assembly quality of the product, ensures the coordination and consistency between various components, and thus improves the overall performance and quality of the product.

[0046] As a parallel embodiment of connecting block 1 and bolt mounting block 2, the bottom of the dovetail groove is a gradually sloping adapting slope from top to bottom in the vertical direction, and the adapting dovetail tenon has a pressing slope that fits the adapting slope (not shown, but can be referenced). Figure 3 When the bolts tighten the leaf spring pressure block, in addition to the frictional tightening between the connecting block 1 and the bolt mounting block 2, the pressing slope of the bolt mounting block 2 also exerts a downward pressing force on the connecting block 1 to enhance the firmness of the connecting block 1 clamped between the four bolt mounting blocks 2.

[0047] Based on the above, the inclination angle of the adapting bevel and the pressing bevel can be less than 5°. The bevel of the dovetail tenon on the bolt mounting block 2 can be directly formed by the design of the mold; the bevel of the adapting bevel on the connecting block 1 can be machined.

[0048] As a parallel implementation of the connecting block 1 and the bolt mounting block 2, this concave-convex mating connection structure can also be designed such that a limiting lower step is provided on the adapter groove 12 on both sides of the connecting block 1 near the lower surface, and a limiting upper step is provided on the corresponding universal protrusion 23 pressing against the limiting lower step (not shown, but can be referenced). Figure 3 In this way, when the bolts tighten the leaf spring pressure block, in addition to the frictional tightening between the connecting block 1 and the bolt mounting block 2, the upper limiting step of the bolt mounting block 2 presses against the lower limiting step, which also exerts a downward pressing force on the connecting block 1, thereby improving the firmness of the connecting block 1 clamped between the four bolt mounting blocks 2.

[0049] In some embodiments, the general protrusion 23 is a T-shaped protrusion; the adapter groove 12 is a T-shaped groove that mates with the T-shaped protrusion (not shown in the figure, but can be referenced). Figure 1 This connection structure also allows the connecting block 1 and the bolt mounting block 2 to form a self-positioning mechanism. The T-shaped protrusion and T-groove have good stability, ensuring a firm connection between components that is not easily loosened or detached, thereby improving the reliability of the entire structure. This connection method can maintain a tight fit even when subjected to certain external forces, effectively reducing the risk of failure due to unstable connections.

[0050] In some embodiments, see Figure 3 As shown, the side of the bolt mounting block 2 has a mating surface 24 that fits the side of the connecting block 1, and the mating surface 24 is located on both sides of the general protrusion 23.

[0051] By using the contact surfaces 24 of the bolt mounting block 2 located on both sides of the universal protrusion 23, the contact area between the bolt mounting block 2 and the connecting block 1 is increased. After the leaf spring pressure block is tightened into the leaf spring assembly 3 by bolts, the friction between the two can be increased, which greatly enhances the connection stability between the bolt mounting block 2 and the connecting block 1, effectively reducing the loosening that may occur between the two during use, thereby ensuring that the entire structure remains stable under various working conditions and improving the reliability of equipment operation.

[0052] In some embodiments, see Figures 1 to 5 As shown, the bolt mounting block 2 is provided with a mounting ramp 22 for mounting bolts, and the bolt hole 21 is provided on the mounting ramp 22; the upper surface of the connecting block 1 is higher than the mounting ramp 22, and the lower surface of the connecting block 1 is flush with the lower surface of the bolt mounting block 2. The design of the above technical solution makes the connecting block 1 between the bolt mounting blocks 2 have a greater thickness than the bolt mounting blocks 2, thereby improving the structural strength of the leaf spring pressure block and ensuring the firmness of the clamping of the leaf spring assembly 3.

[0053] The lower surface of the connecting block 1 is flush with the lower surface of the bolt mounting block 2, so that the lower surface of the leaf spring pressure block is pressed flatly onto the flat leaf spring assembly 3, ensuring surface-to-surface contact between the leaf spring pressure block and the leaf spring assembly 3, and improving the firmness and stability of the pressing.

[0054] In some embodiments, see Figures 1 to 5 As shown, the upper surface of the connecting block 1 is a plane, and the upper surface of the general protrusion 23 is flush with the upper surface of the connecting block 1.

[0055] In some embodiments, the upper surface of the connecting block 1 is an arc-shaped curved surface, and the upper surface of the general protrusion 23 is an arc-shaped curved surface that connects to the upper surface of the connecting block 1 (not shown in the figure, see...). Figure 1 ).

[0056] The upper surface of the connecting block 1 is designed as a flat surface or an arc-shaped surface, which are two structural forms of the connecting block 1. Based on the reinforcing effect of the connecting block 1 protruding between the bolt mounting blocks 2, these two structural forms can be selected according to the space reserved around it. Under the premise of reducing cost and weight, both can maximize the bending section modulus of the leaf spring pressure block, which is beneficial to enhancing the bending deformation resistance of the leaf spring pressure block.

[0057] Specifically, this arc-shaped surface can be an arc-shaped surface that is high in the middle and gradually decreases at both ends from left to right, or it can be an arc-shaped surface that is high in the middle and low at both ends from both sides of the connecting block 1.

[0058] In some embodiments, see Figure 2 As shown, the lower surface of the connecting block 1 is provided with a locating pin hole 11. During the installation of the leaf spring pressure block, the position of the connecting block 1 can be accurately determined, allowing it to quickly and accurately align with the locating pin on the leaf spring assembly 3, effectively improving installation efficiency and accuracy. The positioning function achieved by the locating pin hole 11 in cooperation with the corresponding locating pin also reduces loosening or instability caused by positional deviations, greatly enhancing the stability and reliability of the entire structure. Simultaneously, the locating pin hole 11 facilitates quick location and disassembly / reinstallation of the connecting block 1 during maintenance or replacement, saving maintenance time and costs, and improving the ease of maintenance and service life of the equipment.

[0059] In this application, positioning pin holes 11 are respectively provided at the left and right ends of the lower surface of the connecting block 1. The positioning of the connecting block 1 by the two positioning pin holes 11 also serves to prevent the connecting block 1 from rotating during installation.

[0060] Based on the same inventive concept, this application also provides a vehicle in which the split leaf spring pressure block is used to connect the leaf spring assembly 3 composed of multiple steel leaf springs into a whole.

[0061] The vehicle provided in this application, by employing this split-type leaf spring pressure block, eliminates the need for multiple different molds and the casting of various leaf spring pressure blocks, thereby reducing the types and number of molds and lowering material costs. Simultaneously, this reduces the production costs for automakers, improving production efficiency and economic benefits.

[0062] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
