Description

Technical Field

[0001] The present invention relates to the field of off-road vehicle engineering, and in particular to an installation assembly for an off-road vehicle stabilizer bar and an off-road vehicle. Background Art

[0002] In off-road vehicle engineering, especially within vehicle chassis systems, stabilizer bars play a crucial role in preventing lateral roll during cornering and enhancing stability and safety. However, off-road stabilizer bars are typically thicker and more rigid. In harsh operating conditions such as cross-axles, deserts, and muddy conditions, where there is a significant difference in the up-and-down bounce of the left and right wheels, the stabilizer bar can twist, causing the bushing to twist and compress slightly, and the mounting bracket to twist and deform slightly. This micro-deformation of the bushing can easily allow impurities such as mud and sand to enter the contact surface between the bushing and the frame crossbar, causing unusual noises in the bushing. Micro-deformation of the mounting bracket can also increase the stress in the bracket where the fixing bolts and mounting bracket are fixed, potentially causing the bushing to crack or fall out of the bracket, impacting the driving experience and vehicle performance.

[0003] The current common method for installing a stabilizer bar is to vulcanize the bushing assembly onto the stabilizer bar body. The bushing assembly is then wrapped around a mounting bracket and mounted on the frame crossmember. A concave-convex retaining structure is provided between the bushing and the bracket, and the stabilizer bar bushing is secured by the tightening force of the mounting bracket and frame crossmember mounting bolts. The mounting bracket has two symmetrical through-holes at the bottom, and corresponding nylon clamps are integrally formed with the bushing assembly. These clamps, positioned within the mounting bracket through-holes, prevent the bushing and bracket from rotating axially and radially about the stabilizer bar, thus preventing the bushing assembly from dislodging from the bracket and ensuring a secure fit between the bushing and the frame crossmember. However, the existing technology has many problems under harsh working conditions such as off-roading and rock climbing: First, the off-road vehicle stabilizer bar has high stiffness (about 230N·m) and large wheel rim jump stroke (total stroke of about 300mm). The nylon clamp has insufficient limiting capacity and is easy to disengage from the bracket limiting through-hole. When the stabilizer bar is twisted, the nylon clamp returns to the through-hole. Under repeated movement, the nylon clamp rubs against the mounting bracket, producing abnormal noise. After the nylon clamp is worn off, it loses its limiting function, and the bushing's torsional and axial limiting capacity is reduced, causing the bushing to disengage. Second, the stabilizer bar has a large torsional stroke and torsional stiffness. When twisted, it drives the bushing assembly to compress, causing sliding between the bushing assembly and the frame, and mud and sand enter the frame, causing abnormal noise. Third, when the stabilizer bar is twisted, it causes the bracket to deform slightly, and the stress at the bolt tightening position increases, causing the bracket to crack. Summary of the Invention

[0004] The present application provides an installation assembly for an off-road vehicle stabilizer bar and an off-road vehicle, which can solve the technical problem in the prior art that the nylon clamp is easily dislodged from the limiting through hole of the installation bracket under harsh working conditions.

[0005] In a first aspect, an embodiment of the present application provides a mounting assembly for an off-road vehicle stabilizer bar, comprising: a bushing for being sleeved on the stabilizer bar and a mounting bracket arranged around the outer peripheral side of the upper portion of the bushing, the bottom of the mounting bracket comprising an opening, through which the bottom of the bushing extends out of the mounting bracket; a limiting plate fixedly connected to the bottom of the mounting bracket, the limiting plate covering the portion of the bushing extending out of the mounting bracket, the limiting plate comprising a bottom plate in contact with the mounting bracket and the bushing, and side plates arranged at opposite sides of the bottom plate and extending upward to surround portions of the mounting bracket and the bushing, wherein a side of the bottom plate facing the mounting bracket is provided with an anti-slip structure.

[0006] In combination with the first aspect, in one embodiment, the anti-slip structure is a plurality of square grooves arranged in an array, the intervals between adjacent grooves are equal, and square protrusions of the same shape are formed between adjacent grooves.

[0007] In combination with the first aspect, in one embodiment, an anti-slip coating is provided on the contact surface between the bushing and the limiting plate, and the anti-slip coating is interference fit with the groove.

[0008] In combination with the first aspect, in one embodiment, the heights of both ends of the side panels continuously decrease from the edge to the center, and the decreasing path is a smoothly transitioned curve.

[0009] In combination with the first aspect, in one embodiment, the mounting bracket includes: a bearing portion, which is arranged around the outer peripheral side of the upper portion of the bushing, and the shape of the bearing portion matches the shape of the upper portion of the bushing; and a mounting portion, which is located at both ends of the bearing portion, and a first mounting hole is provided on the mounting portion.

[0010] In combination with the first aspect, in one embodiment, a second mounting hole coaxial with the first mounting hole is provided at both ends of the limit plate along the length direction, and fasteners are sequentially passed through the first mounting hole and the second mounting hole to enable the mounting bracket to be installed on the frame assembly of the off-road vehicle.

[0011] In combination with the first aspect, in one embodiment, the fastener is a bolt or a screw.

[0012] In combination with the first aspect, in one embodiment, flanges extending radially outward are provided at the front and rear ends of the bearing portion. In combination with the first aspect, in one embodiment, the bearing portion and the mounting portion are an integrally formed structure.

[0014] The beneficial effects of the technical solutions provided in the embodiments of the present application include: (1) In the embodiment of the present application, the bottom plate of the limit plate covers the protruding part of the bushing, blocks the axial displacement path, and uses its own strength and rigidity to prevent the bushing from falling out. At the same time, the side plate extends upward to surround the mounting bracket and the bushing part, forming a wrapping constraint and enhancing the axial limit. Even when the off-road vehicle stabilizer bar has high rigidity and large wheel side runout stroke, the axial slippage of the bushing caused by the torsion of the stabilizer bar and the difference in wheel side runout can be prevented, thereby ensuring the stability and safety of the stabilizer bar installation assembly.

[0015] (2) The anti-skid structure of the bottom plate of the limit plate in the embodiment of the present application can increase the friction between the contact surface with the mounting bracket and the bushing. When the stabilizer bar is twisted, the anti-skid structure prevents the bushing from sliding relative to each other, thereby improving the radial anti-skid performance, reducing the risk of mud and sand intrusion, and ensuring the stability of the connection between the stabilizer bar and the frame crossbeam.

[0016] (3) In the embodiment of the present application, after the limit plate is fixedly connected to the mounting bracket, its strength and rigidity can partially bear the force generated by the torsion of the stabilizer bar, reduce the local stress concentration of the mounting bracket, reduce the risk of micro-deformation of the mounting bracket and increased stress at the bolt fixing point caused by torsion, thereby reducing the probability of cracking of the mounting bracket and improving the service life and reliability of the entire stabilizer bar installation assembly.

[0017] (4) In the embodiment of the present application, the bushing is limited and fixed directly by the limiting plate, which reduces the number of parts, thereby reducing the number of parts and the complexity of the production process, reducing manufacturing costs and assembly difficulty, and improving production efficiency.

[0021] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] In off-road vehicle engineering, especially within vehicle chassis systems, stabilizer bars play a crucial role in preventing lateral roll during cornering and enhancing stability and safety. However, off-road stabilizer bars are typically thicker and more rigid. In harsh operating conditions such as cross-axles, deserts, and muddy conditions, where there is a significant difference in the up-and-down bounce of the left and right wheels, the stabilizer bar can twist, causing the bushing to twist and compress slightly, and the mounting bracket to twist and deform slightly. This micro-deformation of the bushing can easily allow impurities such as mud and sand to enter the contact surface between the bushing and the frame crossbar, causing unusual noises in the bushing. Micro-deformation of the mounting bracket can also increase the stress in the bracket where the fixing bolts and mounting bracket are fixed, potentially causing the bushing to crack or fall out of the bracket, impacting the driving experience and vehicle performance.

[0023] The current common method for installing a stabilizer bar is to vulcanize the bushing assembly onto the stabilizer bar body. The bushing assembly is then wrapped around a mounting bracket and mounted on the frame crossmember. A concave-convex retaining structure is provided between the bushing and the bracket, and the stabilizer bar bushing is secured by the tightening force of the mounting bracket and frame crossmember mounting bolts. The mounting bracket has two symmetrical through-holes at the bottom, and corresponding nylon clamps are integrally formed with the bushing assembly. These clamps, positioned within the mounting bracket through-holes, prevent the bushing and bracket from rotating axially and radially about the stabilizer bar, thus preventing the bushing assembly from dislodging from the bracket and ensuring a secure fit between the bushing and the frame crossmember. However, the existing technology has many problems under harsh working conditions such as off-roading and rock climbing: First, the off-road vehicle stabilizer bar has high stiffness (about 230N·m) and large wheel rim jump stroke (total stroke of about 300mm). The nylon clamp has insufficient limiting capacity and is easy to disengage from the bracket limiting through-hole. When the stabilizer bar is twisted, the nylon clamp returns to the through-hole. Under repeated movement, the nylon clamp rubs against the mounting bracket, producing abnormal noise. After the nylon clamp is worn off, it loses its limiting function, and the bushing's torsional and axial limiting capacity is reduced, causing the bushing to disengage. Second, the stabilizer bar has a large torsional stroke and torsional stiffness. When twisted, it drives the bushing assembly to compress, causing sliding between the bushing assembly and the frame, and mud and sand enter the frame, causing abnormal noise. Third, when the stabilizer bar is twisted, it causes the bracket to deform slightly, and the stress at the bolt tightening position increases, causing the bracket to crack.

[0024] The present application provides an installation assembly for an off-road vehicle stabilizer bar and an off-road vehicle, which can solve the technical problem in the prior art that the nylon clamp is easily dislodged from the limiting through hole of the installation bracket under harsh working conditions.

[0025] Figure 1 A schematic diagram of the installation of the off-road vehicle stabilizer bar mounting assembly provided in an embodiment of the present application at the off-road vehicle chassis. Figure 2 A structural diagram of the mounting assembly of the off-road vehicle stabilizer bar provided in the embodiment of the present application. Figure 1 and Figure 2 In the first aspect, an embodiment of the present application provides a mounting assembly for an off-road vehicle stabilizer bar, comprising: a bushing 2 for being sleeved on the stabilizer bar 1 and a mounting bracket 3 arranged around the outer peripheral side of the upper portion of the bushing 2, the bottom of the mounting bracket 3 comprising an opening, through which the bottom of the bushing 2 extends out of the mounting bracket 3; a limiting plate 4 fixedly connected to the bottom of the mounting bracket 3, the limiting plate 4 covering the portion of the bushing 2 extending out of the mounting bracket 3, the limiting plate 4 comprising a bottom plate 41 in contact with the mounting bracket 3 and the bushing 2, and side plates 42 arranged on opposite sides of the bottom plate 41 and extending upward to surround portions of the mounting bracket 3 and the bushing 2, wherein a side of the bottom plate 41 facing the mounting bracket 3 is provided with an anti-slip structure 43.

[0026] Specifically, two bushings 2 are symmetrically located at each end of the stabilizer bar 1 to provide balanced support. When the vehicle is driving, especially around corners or on bumpy roads, the stabilizer bar 1 is subjected to complex forces. These bushings 2 symmetrically support radial and axial forces, preventing excessive displacement or deformation of the stabilizer bar 1 and maintaining vehicle stability.

[0027] The bottom plate 41 of the limit plate 4 is welded to the contact surface between the mounting bracket 3 and the bushing 2. The bottom plate 41 covers the protruding portion of the bushing 2, blocking the axial displacement path and preventing the bushing 2 from dislodging due to its own strength and rigidity. Simultaneously, the side plates 42 extend upward to surround the mounting bracket 3 and bushing 2, forming a wrapping constraint and enhancing axial restraint. Even in the case of an off-road vehicle with high stabilizer bar rigidity and large wheel runout, this prevents axial slippage and dislodgment of the bushing 2 caused by torsion of the stabilizer bar 1 and differential wheel runout, thereby ensuring the stability and safety of the stabilizer bar 1.

[0028] Furthermore, an anti-skid coating is provided on the contact surface between the bushing 2 and the limiting plate 4 , and the anti-skid coating is interference-fitted with the groove 44 .

[0029] Specifically, the anti-slip coating can be rubber lagging. A 3mm thick rubber lagging is added to the bottom of the bushing 2 and vulcanized with the nylon frame at the bottom of the bushing 2. When the stop plate 4 is welded to the stabilizer bar 1 mounting bracket 3, the 3mm thick rubber lagging creates an interference fit with the stop plate 4. The groove 44 on the reinforced stop plate 4 engages with the 3mm thick rubber lagging, preventing slippage between the bushing 2 and the crossbeam when the stabilizer bar 1 is twisted. Because there is a certain amount of compression margin between the rubber lagging and the stop plate 4, no gap is created regardless of the stabilizer bar 1's twisting, preventing the ingress of mud and sand.

[0030] Figure 5 This is a schematic diagram of the structure of the limit plate 4 provided in the embodiment of the present application. Figure 5 In the embodiment of the present application, the anti-slip structure 43 is a plurality of square grooves 44 arranged in an array, the intervals between adjacent grooves 44 are equal, and square protrusions of the same shape are formed between adjacent grooves 44.

[0031] Specifically, the anti-slip structure 43 is integrally formed with the base plate 41 to ensure structural stability and reliability. In the embodiment of the present application, the anti-slip structure 43 significantly increases friction by increasing the roughness and microscopic roughness of the contact surface, effectively preventing relative sliding. When the stabilizer bar 1 is twisted, the anti-slip structure 43 prevents the bushing 2 from sliding relative to the stabilizer bar 1, improving the bushing 2's radial anti-slip performance and ensuring the stability of the connection between the stabilizer bar 1 and the frame crossbar.

[0032] Furthermore, hard particles can be embedded in the raised surface, thereby significantly improving the hardness and wear resistance of the surface and enhancing the anti-slip effect. At the same time, the shape of the groove 44 of the anti-slip structure 43 can be not only square, but also triangular, semicircular or polygonal, etc., which can be selected according to different force requirements and contact surface characteristics, and is not limited here.

[0033] In a specific embodiment, the groove 44 can also be triangular in shape, and the thickness of the limit plate 4 is 3 mm. As a result, the limit plate 4 has good flexibility and impact resistance while ensuring its own strength. The anti-slip structure 43 is composed of 13 grooves 44, and the anti-slip structure 43 runs through both sides of the limit plate 4, so that the anti-slip effect is more uniform. The angle between the two sides of each groove 44 is 120°, the depth is 1.5 mm, the distance between the bottoms of two adjacent grooves 44 is 6 mm, the distance between the upper edges is 1 mm, and the total length of the 13 grooves 44 is 75 mm. Therefore, on the one hand, sufficient anti-slip performance can be provided in a limited space, and on the other hand, the overall structural stability and installation convenience of the limit plate 4 are not affected.

[0034] Figure 6 This is a side view of the limiting plate 4 provided in the embodiment of the present application. Figure 6 In the embodiment of the present application, the heights of both ends of the side panel 42 decrease continuously from the edge to the center, and the decreasing path is a smoothly transitioned curve.

[0035] Specifically, for the thickness of the side plate 42, a setting with thinner edges and thicker centers can be adopted. On the one hand, this can ensure that the bushing 2 is better pressed into the limiting plate 4 when the limiting plate 4 is welded to the bracket. On the other hand, it can also reduce the weight of the side plate 42 while ensuring the strength of the limiting plate 4.

[0036] In a specific embodiment, the minimum height at the center of the side plate 42 is 4.5 mm, and a 45° chamfer is provided at the edge of the side plate 42. The 45° chamfer serves as a guide during assembly, facilitating precise docking and rapid assembly of the stop plate 4, the mounting bracket 3, and the bushing 2, thereby improving production efficiency. In specific applications, the minimum height at the center of the side plate 42 can be set according to actual needs, as long as the mounting bracket 3 and the bushing 2 are partially enclosed. This is not a limitation here.

[0037] Figure 3 This is another structural diagram of the mounting assembly of the off-road vehicle stabilizer bar provided in an embodiment of the present application. Figure 3 In the embodiment of the present application, the mounting bracket 3 includes: a bearing portion 31, the bearing portion 31 is arranged around the outer peripheral side of the upper portion of the bushing 2, and the shape of the bearing portion 31 matches the upper shape of the bushing 2; a mounting portion 32, the mounting portion 32 is located at both ends of the bearing portion 31, and a first mounting hole 33 is opened on the mounting portion 32.

[0038] Specifically, the shape of the load-bearing portion 31 matches the shape of the upper portion of the bushing 2, thereby ensuring the load-bearing capacity and stability of the mounting bracket 3 on the stabilizer bar 1. The first mounting hole 33 is used to connect the stabilizer bar 1 to the upper cross member of the off-road vehicle's frame assembly, ensuring the entire stabilizer bar 1 is fixed. As a result, the stabilizer bar 1 can effectively improve the vehicle's roll stiffness, reducing the roll amplitude and slowing the roll gradient when the vehicle turns, thereby improving the vehicle's handling performance.

[0039] In the embodiment of the present application, a second mounting hole 45 coaxial with the first mounting hole 33 is provided at both ends of the limit plate 4 along the length direction, and fasteners are sequentially passed through the first mounting hole 33 and the second mounting hole 45 so that the mounting bracket 3 can be installed on the frame assembly of the off-road vehicle.

[0040] Specifically, the fasteners can be bolts, screws or pins that match the first mounting hole 33 and the second mounting hole 45, thereby ensuring a tight fit between the mounting bracket 3 and the limit plate 4, and preventing the two from loosening or shifting due to vibration or other external forces during vehicle driving.

[0041] Figure 4 This is a schematic diagram of the structure of the off-road vehicle stabilizer bar provided in the embodiment of the present application. Figure 4 In the embodiment of the present application, after the limit plate 4 is fixedly connected to the mounting bracket 3, its strength and rigidity can partially bear the force generated by the torsion of the stabilizer bar 1, reduce the local stress concentration of the mounting bracket 3, and reduce the risk of micro-deformation of the bracket caused by torsion and increased stress at the bolt fixing point, thereby reducing the probability of bracket cracking and improving the service life and reliability of the entire stabilizer bar 1.

[0042] In the embodiment of the present application, flanges 34 extending radially outward are provided at the front and rear ends of the bearing portion 31 .

[0043] Specifically, flange 34 extends radially outward along the shape of bearing portion 31, thereby increasing the structural strength of mounting bracket 3 and effectively dissipating stress. Furthermore, the middle portion of bearing portion 31 is thinner than the front and rear ends where flange 34 is located, significantly reducing the weight of the entire mounting bracket 3 and making the vehicle more maneuverable and responsive during driving.

[0044] In the embodiment of the present application, the bearing portion 31 and the mounting portion 32 are integrally formed. Thus, the overall strength and rigidity of the mounting bracket 3 are higher, and the mounting bracket 3 can be made of high-strength aluminum alloy or magnesium alloy.

[0045] Figure 7 This is another structural diagram of the mounting assembly of the off-road vehicle stabilizer bar provided in the embodiment of the present application. Figure 7As shown, limit blocks are circumferentially provided at the front and rear ends of the bushing 2. The limit blocks further limit the movement range of the bushing 2 in the axial direction, preventing the bushing 2 from axially displacing between the stabilizer bar 1 and the mounting bracket 3.

[0046] In summary, in the embodiment of the present application, the bottom plate 41 of the limit plate 4 covers the protruding part of the bushing 2, blocks the axial displacement path, and uses its own strength and rigidity to prevent the bushing 2 from falling out. At the same time, the side plate 42 extends upward to surround the mounting bracket 3 and the bushing 2, forming a wrapping constraint, enhancing the axial limit, and even when the stabilizer bar 1 has a large rigidity and a large wheel side runout stroke, it can prevent the bushing 2 from axially slipping and falling out due to the torsion of the stabilizer bar 1 and the difference in wheel side runout, thereby ensuring the stability and safety of the stabilizer bar 1 assembly; the anti-skid structure 43 provided on the bottom plate 41 of the limit plate 4 in the embodiment of the present application can increase the friction with the contact surface of the mounting bracket 3 and the bushing 2. When the stabilizer bar 1 is twisted, the anti-skid structure 43 prevents the bushing 2 from Relative slippage improves radial anti-slip performance, reduces the risk of mud and sand intrusion, and ensures the stability of the connection between the stabilizer bar 1 and the frame crossbeam; in the embodiment of the present application, after the limit plate 4 is fixedly connected to the mounting bracket 3, its strength and rigidity can partially bear the force generated by the torsion of the stabilizer bar 1, reduce local stress concentration in the mounting bracket 3, reduce the risk of micro-deformation of the bracket caused by torsion and increased stress at the bolt fixing point, thereby reducing the probability of cracking of the mounting bracket 3 and improving the service life and reliability of the entire stabilizer bar 1; in the embodiment of the present application, the bushing 2 is limited and fixed directly by the limit plate 4, which reduces the number of parts, thereby reducing the number of parts and the complexity of the production process, reducing manufacturing costs and assembly difficulty, and improving production efficiency.

[0047] In a second aspect, an embodiment of the present application provides an off-road vehicle, comprising a mounting assembly for an off-road vehicle stabilizer bar according to any one of the above embodiments.

[0048] When driving an off-road vehicle, if you encounter a situation where you need to make sharp turns or climb a slope, the limit plate can limit excessive torsion of the stabilizer bar, maintain the vehicle's handling stability, and prevent axial displacement of the bushing, ensuring a reliable connection between the stabilizer bar and the mounting bracket, blocking the intrusion of mud and sand, and reducing the risk of wear and corrosion, thereby improving the off-road vehicle's passability and handling in harsh road conditions and ensuring stable and safe driving.
