Description

Technical Field

[0001] This utility model relates to the field of vehicle body parts technology, and more specifically, to a lateral stabilizer bar device for mountain tractors. Background Technology

[0002] The lateral stabilizer bars used in current mountain tractors are mostly made of high-strength alloy steel (such as 40Cr, 20Mn2, etc.) through forging, welding, and heat treatment processes to ensure mechanical performance in resisting lateral loads and deformation during mountain operations. Regarding the connection to the chassis, the stabilizer bar has a symmetrical U-shaped structure. Its two ends are connected to the left and right supports of the tractor's front axle (or suspension system) and the frame crossbeams via ball joints, rubber bushings, or pin assemblies, achieving a rigid-flexible connection. The rubber bushings buffer some high-frequency vibrations, while the ball joints or pins ensure the stabilizer bar can rotate flexibly when the vehicle body tilts laterally, avoiding stress concentration at the connection points. From the perspective of function and principle, the lateral stabilizer bar is the core component that ensures the lateral stability of the tractor: when the tractor is traveling or turning on a mountainous and sloping road, the suspension systems on both sides of the vehicle will have a height difference due to terrain differences or centrifugal force. At this time, the U-shaped stabilizer bar will undergo torsional deformation with the displacement of the suspensions on both sides, thereby generating an anti-torsional torque opposite to the lateral tilt direction of the vehicle body, offsetting part of the lateral tilt force, effectively suppressing excessive tilt of the vehicle body, and reducing the risk of rollover; at the same time, its rigid structure can help maintain the lateral positioning of the suspension system, ensuring the stability of the wheel contact posture, and providing a stable vehicle body foundation for agricultural implement operations.

[0003] While the integrated U-shaped stabilizer bar meets basic structural strength requirements, its design suffers from significant limitations in versatility and economy, making it unsuitable for the diverse applications of mountain tractors. Specifically, existing stabilizer bars employ a fixed, integrated structure. The span of the U-shaped bar (the distance between the two connection points) and its overall length are fixed dimensions predetermined during production, making adjustments impossible based on tractor model variations. Given the diverse range of mountain tractor models, with different tonnages (e.g., 20 hp, 40 hp, 60 hp) and wheelbases, there are significant differences in underbody front axle spacing and frame crossbeam mounting positions. This necessitates a stabilizer bar of corresponding length for each model – a single-size stabilizer bar can only accommodate one or two specific models, failing to meet the needs of multiple tractor types. This design not only causes great inconvenience to users—the vehicle model must be accurately matched when purchasing or replacing stabilizer bars, and misjudging the vehicle parameters can easily lead to purchasing the wrong model, making it impossible to install the stabilizer bar and delaying the work progress—it also puts cost pressure on manufacturers: to meet the needs of different vehicle models, companies need to develop stabilizer bar molds of various lengths, and at the same time, they need to organize the production, warehousing and logistics management of different models of stabilizer bars separately, which further increases the overall production cost and also causes the dispersion and waste of resources.

[0004] In summary, in order to overcome the limitations of existing integrated stabilizer bars in adapting to multiple vehicle models, reduce the risk of users purchasing the wrong product and reduce enterprise production costs, and improve resource utilization efficiency, it is necessary to solve the problems of fixed and non-adjustable length and low versatility of existing stabilizer bars. This would enable a single stabilizer bar to be adapted to mountain tractors of various tonnages and wheelbases, while reducing the mold development and management costs for enterprises, and providing users with a convenient and low-cost replacement solution. Summary of the Invention

[0005] The present invention provides a lateral stabilizer bar device for mountain tractors, which aims to solve the problem that existing lateral stabilizer bars are of a fixed size and their length cannot be adjusted to match different vehicle models, resulting in limited installation and low versatility.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lateral stabilizer bar device for a mountain tractor, comprising an adjusting cylinder, lateral stabilizer bar bodies symmetrically distributed on both sides of the adjusting cylinder, a first circular hole, a second circular hole, a third circular hole, a fourth circular hole, an arc-shaped connecting hole, a straight connecting hole, and an enlarged hole opened on the inner side of the adjusting cylinder, two positioning push disks movably disposed in the first and second circular holes, and a displacement control mechanism mounted on the adjusting cylinder. The first, second, third, and fourth circular holes are arranged in a circumferential array, the first and second circular holes are arranged opposite each other, and the openings on both sides extend through the surface of the adjusting cylinder. The number of arc-shaped connecting holes is set to two, one of which is connected to the first and third circular holes, and the other is connected to the second circular hole. The two transverse stabilizer bars are connected to each other, and the two transverse stabilizer bars are connected to each other. The two transverse stabilizer bars are bent, and the bent parts of the two transverse stabilizer bars are respectively inserted into the corresponding first or third transverse stabilizer bars and fixed to the corresponding positioning push disks by hexagonal bolts. The displacement control mechanism includes an execution module, a power transmission module and a drive module installed in the adjustment cylinder. The output end of the execution module is connected to the input end of the power transmission module. The output end of the power transmission module is connected to the two positioning push disks. The output end of the drive module is connected to the input end of the execution module. The drive module synchronously controls the two positioning push disks to move closer or further apart through the execution module and the power transmission module.

[0007] In a preferred embodiment, the execution module includes a bidirectional screw rotatably connected in a fourth circular hole and push rings symmetrically threaded to the outer sides of both ends of the bidirectional screw. Rotating the bidirectional screw drives the two push rings to move closer or further apart.

[0008] In a preferred embodiment, the power transmission module includes two straight connecting plates movably connected in the straight connecting hole, a guide rod fixedly connected in the third circular hole, transition rings symmetrically and movably connected to the outer sides of both ends of the guide rod, and arc-shaped connecting plates movably connected in the two arc-shaped connecting holes. The push ring on the same side and the corresponding transition ring are fixedly connected by the straight connecting plate, and the transition ring on the same side and the corresponding positioning push plate are fixedly connected by the arc-shaped connecting plate.

[0009] In a preferred embodiment, the drive module includes a first bevel gear fixedly connected to the outer side of the middle of the bidirectional screw, a second bevel gear rotatably connected to the enlarged hole, and a knob rotatably connected to the outer wall of the adjusting cylinder. The first bevel gear and the second bevel gear are meshed together, and the knob is fixedly connected to the second bevel gear via a shaft.

[0010] In a preferred embodiment, a protective sleeve is provided on the outer side of the knob, and a pressure plate that is tightly attached to the inner side of the protective sleeve is fixedly connected to the knob surface.

[0011] In a preferred embodiment, a mounting bracket is fixedly connected to the outer wall of the regulating cylinder, and the protective sleeve and the mounting bracket are fixedly connected by multiple sets of screws.

[0012] In a preferred embodiment, rubber sealing plugs are provided at the perforations of the first and second circular holes on the side away from the insertion end of the transverse stabilizer bar body, and a fixing ring is fixedly connected to the surface of the rubber sealing plug.

[0013] In a preferred embodiment, mounting sleeves are provided on the outer sides of the two lateral stabilizer bar bodies, and ear plates are fixedly connected to the mounting sleeves.

[0014] The beneficial effects of this utility model are as follows: This invention splits the integrated transverse stabilizer bar body into two independent units and sets an adjustment cylinder with a multi-hole structure in the middle, which allows for free adjustment of the insertion depth of the two transverse stabilizer bar bodies, realizing adaptive adjustment of the overall length. Operators can adjust the insertion depth according to the difference in tractor models, eliminating the need for a special stabilizer bar, reducing the risk of incorrect purchase, reducing mold and management costs at the production end, and improving the versatility of the device.

[0015] This utility model uses a displacement control mechanism to operate the positioning push plate, thereby achieving reliable fixing and symmetrical adjustment of the rod body. The push plate is bolted to lock the rod body, and the mechanism can drive its movement synchronously, maintaining the symmetrical distribution of the rod body, avoiding imbalance of the center of gravity, ensuring balanced lateral force on the tractor, and improving operational stability.

[0016] This utility model uses a detachable protective sleeve on the outside of the knob and a pressure plate on the inside to protect the drive component and prevent accidental operation. The protective sleeve blocks impurities and extends the service life; the pressure plate resists vibration, prevents the knob from turning accidentally and causing length deviation, reduces safety risks, and improves reliability in mountainous environments.

[0025] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] Refer to the instruction manual appendix Figures 1 to 7A lateral stabilizer bar device for a mountain tractor includes an adjusting cylinder 1, lateral stabilizer bar bodies 2 symmetrically distributed on both sides of the adjusting cylinder 1, a first circular hole 301, a second circular hole 302, a third circular hole 303, a fourth circular hole 304, an arc-shaped connecting hole 305, a straight connecting hole 306, and an enlarged hole 307 opened on the inner side of the adjusting cylinder 1, two positioning push disks 4 movably disposed in the first circular hole 301 and the second circular hole 302, and a displacement control mechanism mounted on the adjusting cylinder 1. The first circular hole 301, the second circular hole 302, the third circular hole 303, and the fourth circular hole 304 are arranged in a circumferential array. The first circular hole 301 and the second circular hole 302 are arranged opposite each other, and the openings on both sides extend out of the surface of the adjusting cylinder 1. The number of arc-shaped connecting holes 305 is set to two, one of which is connected to the first circular hole 301 and the third circular hole 303, and the other arc-shaped connecting hole... 305 is connected to the second circular hole 302 and the third circular hole 303. The direct connection hole 306 is connected to the third circular hole 303 and the fourth circular hole 304. The enlarged hole 307 is connected to the fourth circular hole 304. The two transverse stabilizer bodies 2 are provided with bent parts, and the bent parts of the two transverse stabilizer bodies 2 are respectively inserted into the corresponding first circular hole 301 or third circular hole 303, and are fixed to the corresponding positioning push disk 4 by hexagonal bolts. The displacement control mechanism includes an execution module, a power transmission module and a drive module installed in the adjusting cylinder 1. The output end of the execution module is connected to the input end of the power transmission module. The output end of the power transmission module is connected to the two positioning push disks 4. The output end of the drive module is connected to the input end of the execution module. The drive module synchronously controls the two positioning push disks 4 to move closer or farther away from each other through the execution module and the power transmission module.

[0027] It should be noted that the adjusting cylinder 1, as the main frame, forms an adjustment channel through a variety of circular holes inside. The total length of the lateral stabilizer bar bodies 2 on both sides can be adjusted by changing the insertion depth. The shifting control mechanism is the core adjustment component. Through the drive module, it drives the execution module and the power transmission module, and can synchronously control the relative movement of the two positioning push disks 4, thereby accurately adjusting the insertion depth of the lateral stabilizer bar bodies 2 to meet the length adaptation requirements of different vehicle models. The bolt fixing method between the positioning push disks 4 and the lateral stabilizer bar bodies 2 not only ensures the connection strength, but also provides an operational basis for subsequent length adjustment.

[0028] Refer to the instruction manual appendix Figure 4 The execution module includes a bidirectional screw 501 rotatably connected in the fourth circular hole 304 and push rings 502 symmetrically threaded to the outer sides of both ends of the bidirectional screw 501. Rotating the bidirectional screw 501 drives the two push rings 502 to move closer or further apart.

[0029] It should be noted that the execution module is the power execution component that realizes the length adjustment. The rotation of the bidirectional screw 501 in the fourth circular hole 304 can drive the two push rings 502 to move closer or further apart through the threaded transmission. This symmetrical adjustment method can ensure that the extension and retraction of the transverse stabilizer body 2 on both sides are consistent, avoid the shift of the device's center of gravity caused by unilateral adjustment, and ensure the stability and symmetry of the length adjustment.

[0030] Refer to the instruction manual appendix Figure 4 and Figure 6 The power transmission module includes two straight connecting plates 503 movably connected in the straight connecting hole 306, a guide rod 506 fixedly connected in the third circular hole 303, transition rings 504 symmetrically movably connected to the outer sides of both ends of the guide rod 506, and arc-shaped connecting plates 505 movably connected in the two arc-shaped connecting holes 305. The push ring 502 on the same side and the corresponding transition ring 504 are fixedly connected by the straight connecting plate 503, and the transition ring 504 on the same side and the corresponding positioning push disk 4 are fixedly connected by the arc-shaped connecting plate 505.

[0031] It should be noted that the power transmission module plays a role in force transmission and guidance. The straight connecting plate 503 transmits the power of the push ring 502 to the transition ring 504. The guide rod 506 provides stable guidance for the movement of the transition ring 504, preventing deviation and jamming during the adjustment process. The arc-shaped connecting plate 505 adapts to the path of the arc-shaped connecting hole 305, converting the linear movement of the transition ring 504 into the corresponding movement of the positioning push disk 4, realizing the efficient transmission of power between different channel structures and ensuring the continuity of the adjustment action.

[0032] Refer to the instruction manual appendix Figure 4 The drive module includes a bevel gear 507 fixedly connected to the outer side of the middle part of the bidirectional screw 501, a bevel gear 508 rotatably connected to the enlarged hole 307, and a knob 509 rotatably connected to the outer wall of the adjusting cylinder 1. The bevel gear 507 and the bevel gear 508 are meshed together, and the knob 509 is fixedly connected to the bevel gear 508 through a shaft.

[0033] It should be noted that the drive module is the power input component of the entire adjustment system. Rotation of the knob 509 drives the second bevel gear 508 to rotate via a shaft transmission, and then, through meshing with the first bevel gear 507, drives the bidirectional screw 501 to rotate. This bevel gear transmission structure changes the direction of force transmission, allowing the operator to easily perform rotational operations from the side of the adjustment cylinder 1, reducing the difficulty of adjustment and improving operational convenience.

[0034] Another improved embodiment based on the drive module design replaces the combination of knob 509 and bevel gear 508 with a "worm gear drive + hand crank" structure. A worm, worm wheel, and hand crank are added. The worm wheel is fixed in the middle of the bidirectional screw 501. The worm meshes with the worm wheel and its end is connected to the hand crank. This structure, through the self-locking characteristics of the worm gear, replaces the limiting function of the original pressure plate 7. After adjustment, it automatically locks, preventing loosening caused by vibration. Simultaneously, the worm gear transmission ratio reaches 1:20, amplifying the lever arm during hand cranking by 20 times. The operator only needs to apply 1 / 20th of the force required to operate the knob 509 to complete the adjustment, making it particularly suitable for scenarios where hand strength is difficult in low-temperature environments, significantly improving operational convenience.

[0035] Refer to the instruction manual appendix Figure 7 A protective sleeve 6 is provided on the outside of the knob 509, and a pressure plate 7 that is tightly attached to the surface of the knob 509 is fixedly connected to the inside of the protective sleeve 6.

[0036] It should be noted that the protective sleeve 6 provides physical protection for the knob 509, preventing damage to the knob 509 caused by external collisions and dust erosion. The pressure plate 7 is in close contact with the surface of the knob 509, and restricts the free rotation of the knob 509 through friction. This effectively avoids the length deviation caused by the knob 509 rotating unexpectedly due to vibration when the tractor is operating on bumpy mountain terrain, and ensures the stability of the device after adjustment.

[0037] Refer to the instruction manual appendix Figure 5 An installation bracket 8 is fixedly connected to the outer wall of the regulating cylinder 1, and the protective sleeve 6 and the installation bracket 8 are fixedly connected by multiple sets of screws.

[0038] It should be noted that the mounting bracket 8 provides a fixed base for the protective sleeve 6. The protective sleeve 6 is firmly connected to the adjusting cylinder 1 by multiple sets of screws, ensuring that the protective sleeve 6 will not loosen or fall off under the severe vibration environment of the tractor. This fixing method not only facilitates the disassembly and maintenance of the protective sleeve 6, but also ensures the long-term effectiveness of its protective function.

[0039] Refer to the instruction manual appendix Figure 5 A rubber sealing plug 9 is provided at the perforation of the first round hole 301 and the second round hole 302 on the side away from the insertion end of the transverse stabilizer bar body 2, and a fixing ring 10 is fixedly connected to the surface of the rubber sealing plug 9.

[0040] It should be noted that the rubber sealing plug 9 is inserted into the exposed holes of the first round hole 301 and the second round hole 302, which can effectively prevent external dust, moisture and other impurities from entering the channel, and avoid the internal transmission components from being worn or stuck due to contamination. The fixing ring 10 facilitates the installation and removal of the rubber sealing plug 9, and at the same time enhances the tightness of the sealing plug and the channel, thus improving the sealing effect.

[0041] Refer to the instruction manual appendix Figure 1 and Figure 2 Two transverse stabilizer bar bodies 2 are provided with mounting sleeves 11 on their outer sides, and ear plates 12 are fixedly connected to the mounting sleeves 11.

[0042] Another improved embodiment based on the design of rubber sealing plug 9 and fixing ring 10 replaces rubber sealing plug 9 and fixing ring 10 with a combination of "telescopic metal dust cover + lip seal". One end of the metal dust cover is fixed to the outer wall of the transverse stabilizer bar body 2, and the other end is connected to the surface of the adjusting cylinder 1. The lip seal is embedded in the groove of the hole wall of the first round hole 301 and the second round hole 302 and closely adheres to the surface of the transverse stabilizer bar body 2. In the new structure, the metal dust cover can deform synchronously with the extension and retraction of the transverse stabilizer bar body 2, always maintaining a sealed state, solving the problem that the original rubber sealing plug 9 needs to be repeatedly disassembled during adjustment. The lip seal is made of polyurethane material, and the lip structure of the cross section forms an interference fit with the bar body, which significantly improves the dustproof level. At the same time, the seal has a built-in spring ring, which can still maintain the clamping force after long-term wear, extending the service life.

[0043] It should be noted that the mounting sleeve 11 and the ear plate 12 together constitute the connecting parts between the device and the tractor body. The ear plate 12 can be fixed to the tractor frame or suspension system by bolts or other connecting parts. The mounting sleeve 11 plays a role in reinforcing and positioning the end of the lateral stabilizer bar body 2, ensuring that the lateral stabilizer bar device can stably transmit lateral force and ensure the lateral stability of the tractor during operation.

[0044] Working principle: When it is necessary to replace or adapt to different vehicle models, first operate the knob 509 in the drive module. The power transmission module drives the bidirectional screw 501 of the execution module to rotate, causing the two positioning push disks 4 in the first and second round holes 301 and 302 to move synchronously to the outermost position, reserving the maximum space for the insertion of the lateral stabilizer bar body 2. Then, insert the bent parts of the two lateral stabilizer bar bodies 2 from both sides of the adjusting cylinder 1 into the corresponding first round hole 301 or third round hole 303, until the end of the bar abuts against the positioning push disk 4. Fix the two with hexagonal bolts to complete the initial connection. According to the length required by the actual vehicle model, operate the drive module again, via the bevel gear 507, The bevel gear 508 drives the bidirectional screw 501 to rotate, causing the push ring 502 to push the positioning push disk 4 to move through the straight connecting plate 503, transition ring 504 and arc-shaped connecting plate 505, thereby adjusting the insertion depth of the lateral stabilizer bar body 2 until the appropriate length is reached. After adjustment, the protective sleeve 6 is fixed to the surface of the mounting bracket 8 on the adjusting cylinder 1, so that the internal pressure plate 7 is tightly attached to the knob 509 to prevent vibration and loosening. At the same time, the rubber sealing plug 9 is inserted into the exposed holes of the first round hole 301 and the second round hole 302, and the fixing ring 10 ensures a seal to prevent dust from entering. Finally, the device is fixed to the tractor body through the mounting sleeve 11 and ear plate 12, completing the entire replacement and adaptation process.

[0045] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
