Description

Technical Field

[0001] The present invention relates to the technical field of off-road vehicles, and in particular to an off-road vehicle anti-rollover active hydraulic stabilization device and a vehicle. Background Art

[0002] With the popularity of off-road sports and the growing demand for outdoor adventures, off-road vehicles are increasingly used in complex terrain environments. Whether crossing the desert, climbing steep slopes, or wading across rivers, vehicles must not only have powerful power and a high chassis ground clearance, but also have excellent stability and anti-rollover capabilities. However, in actual off-road scenarios, the balance between the vehicle's anti-roll performance and off-road performance has always been a major challenge facing the industry.

[0003] Traditional lateral stabilizer bars rigidly connect the left and right suspensions, which can effectively suppress body roll on flat roads or when cornering at high speeds, significantly improving the vehicle's handling and safety. However, when the vehicle is driving on an off-road road full of deep pits and boulders, this rigid connection will severely limit the suspension's up and down travel, causing the wheels to be unable to fully adhere to the ground, weakening the vehicle's grip, and even causing the wheels to hang in the air, greatly reducing the vehicle's passability and putting the vehicle in trouble.

[0004] Although some existing active or semi-active stabilizers have alleviated the contradiction between anti-roll and passability to a certain extent, most of them have complex structures and high costs. Some devices use a large number of precision electronic components and complex hydraulic pipeline systems, which not only increase the vehicle's curb weight and energy consumption, but also in extreme environments, electronic components are easily affected by dust and moisture and fail. Complex hydraulic structures may also cause loose connections and oil leakage due to vibration and impact, and reliability is difficult to guarantee. Therefore, the development of an off-road vehicle anti-rollover active hydraulic stabilizer that can effectively improve anti-rollover capabilities while taking into account off-road passability, with a simple structure and high reliability, has become an issue that the industry urgently needs to solve. Summary of the invention

[0005] The purpose of the present invention is to provide an off-road vehicle anti-rollover active hydraulic stabilizer and a vehicle, which has a simple structure, good reliability, strong anti-rollover capability without reducing off-road performance, so as to ensure the safety of the driver and passengers and overcome the complex structure and insufficient reliability of the prior art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions: In a first aspect, the present invention provides an active hydraulic stability device for off-road vehicles to prevent rollover, which includes a connecting shaft. A plurality of leaf springs are arranged on the connecting shaft. Two first connecting sleeves are arranged between the leaf springs and on the side of the connecting shaft. One end of the first connecting sleeve is rotatably connected to a fixed block. A buffer mechanism is connected to the side of the first connecting sleeve through a rotatably connected first rotating shaft. An auxiliary mechanism is provided at one end of the connecting shaft.

[0007] Further, the buffer mechanism includes a connecting rod. The first end of the connecting rod is installed on the side of the first rotating shaft. A first spring is connected to the connecting rod. The second end of the connecting rod is connected to one end of a sliding disk. The other end of the sliding disk is provided with a hydraulic cylinder. A piston is slidably arranged in the hydraulic cylinder and the piston is connected to the second end of the connecting rod. The second end of the connecting rod is slidably installed in the hydraulic cylinder. A perforation is formed on the side of the piston. Hydraulic oil is provided in the hydraulic cylinder.

[0008] Further, the auxiliary mechanism includes third connecting sleeves arranged on both sides of the connecting shaft. One end of the third connecting sleeve is rotatably connected to a second rotating shaft. The side of the second rotating shaft is connected to the first end of a movable sleeve provided with a cylindrical groove. The second end of the movable sleeve is connected to an anti-roll bar. A fixed rod is provided on one side of the fixed block. The anti-roll bar is connected to the fixed rod.

[0009] Further, a central bolt column is installed in the leaf spring. Both ends of the central bolt column penetrate through the leaf spring and are respectively connected with a limit plate. The limit plates are fixedly connected by a plurality of bolts and nuts are correspondingly arranged at one ends of the bolts; a second connecting sleeve is provided on the limit plate close to the connecting shaft, and the second connecting sleeve is connected to the connecting shaft.

[0010] Further, a top cover is provided at the end of the hydraulic cylinder far from the sliding disk. A fixed piston is provided in the hydraulic cylinder, and the top cover abuts against the fixed piston.

[0011] Further, a movable groove is formed in the fixed rod, and a second spring is provided in the movable groove; a connecting column adapted to the movable groove is provided on the side of the anti-roll bar. One end of the second spring is installed on the inner wall of the movable groove, and the other end of the second spring is installed on the connecting column.

[0012] Further, both ends of the leaf spring are provided with eyelets.

[0013] Further, a sealing groove is provided on the side of the hydraulic cylinder close to the sliding disk, and a sealing ring adapted to the sealing groove is installed at the second end of the connecting rod.

[0014] Further, one end of the first spring is installed on the connecting rod, and the other end is installed on the sliding disk.

[0015] In a second aspect, the present invention provides a vehicle, including the above-mentioned active hydraulic anti-rollover device for off-road vehicles.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention provides an active hydraulic anti-rollover device for off-road vehicles. Through the cooperation of a linkage shaft, a plurality of leaf springs, a buffer mechanism and an auxiliary mechanism, the shock absorption and buffering performance of the off-road vehicle is improved, the anti-rollover ability is increased, and the layout of the components of the stabilization device is reasonable, and the overall structure is compact, without occupying too much vehicle space. At the same time, the connection methods of the components are simple and clear, which is convenient for installation and later maintenance.

[0017] Specifically, in the buffer mechanism of the present invention, by setting a connecting rod and a first spring, etc., when the vehicle is turning, the forces received at both ends of the wheels are different, and one end of the vehicle will tilt. At this time, the first spring will be compressed to drive the piston in the hydraulic column to slide in the hydraulic column. The hydraulic oil in the hydraulic column slides through the perforation to the other end of the hydraulic column. When the first spring rebounds, the hydraulic oil at the other end slides back to the initial position through the perforation. Since the aperture of the perforation is small, it can prevent the first spring from rebounding quickly, thereby forming a buffering effect.

[0018] Specifically, in the auxiliary mechanism, by setting a second rotating shaft and an anti-roll bar, when the vehicle turns and tilts, one end of the anti-roll bar is subjected to a certain extrusion and twists, and the anti-roll bar fixed at the other end counteracts the twisting force, generating a reverse torsion force, which is transmitted to the wheels through the suspension system, providing a reverse supporting force to the vehicle body, pulling one end of the vehicle straight, and preventing the vehicle from tipping over. When the anti-roll bar drives the second rotating shaft to rotate, one end of the connecting column slides in the movable groove, and the second spring is stretched or compressed. Through the deformation and rebound of the second spring, the anti-roll bar is driven to return to its position, helping the anti-roll bar to return to its position more easily, helping the operator to stabilize the vehicle, and improving the applicability of the device.

[0019] Specifically, by setting leaf springs and limit plates, etc., after welding a plurality of leaf springs together, the leaf springs are fixed between each other through the limit plates and bolts, and the position of the limit plates is fixed by nuts. A plurality of leaf springs bear a certain load on the vehicle body, and the received shock force is offset by the elasticity of the leaf springs. When the vehicle is driving on an uneven road surface, the friction between the plurality of leaf springs provides a certain damping, reducing the rebound shock, and further reducing the vibration transmitted to the vehicle body, enabling the operator to maintain the balance of the vehicle and helping to better control the driving of the vehicle.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0036] Embodiment 1 Please refer to Figures 1-9, the present invention provides a technical solution: an active hydraulic stability device for off-road vehicles to prevent rollover, which includes a connecting shaft 4. A plurality of leaf springs 1 are arranged on the connecting shaft 4. Two first connecting sleeves 5 are arranged between the leaf springs 1 and on the side of the connecting shaft 4. One end of the first connecting sleeve 5 is rotatably connected to a fixed block 6. A buffer mechanism 2 is connected to the side of the first connecting sleeve through a rotatable first rotating shaft 11. One end of the connecting shaft 4 is provided with an auxiliary mechanism; the buffer mechanism 2 includes a connecting rod 21. The first end of the connecting rod 21 is installed on the side of the first rotating shaft 11. A first spring 22 is connected to the connecting rod 21. One end of the first spring 22 is installed on the connecting rod 21, and the other end is installed on a sliding disk 23. The second end of the connecting rod 21 is connected to one end of the sliding disk 23. The other end of the sliding disk 23 is provided with a hydraulic cylinder 24. A piston 25 is slidably arranged in the hydraulic cylinder 24 and the piston 25 is connected to the second end of the connecting rod 21. The second end of the connecting rod 21 is slidably installed in the hydraulic cylinder 24. A through hole 26 is opened on the side of the piston 25. Hydraulic oil 27 is arranged in the hydraulic cylinder 24; one end of the hydraulic cylinder 24 away from the sliding disk 23 is provided with a top cover 12. A fixed piston 13 is arranged in the hydraulic cylinder 24. The top cover 12 abuts against the fixed piston 13. When the off-road vehicle needs to turn, one end of the vehicle body will tilt to a certain extent, and the bottom of the vehicle will squeeze one end of the top cover 12, and at the same time drive the first spring 22 to be compressed. The top cover 12 drives the hydraulic cylinder 24 to slide, and then drives the piston 25 at one end of the connecting rod 21 to slide in the hydraulic cylinder 24, mobilizing the hydraulic oil 27 in the hydraulic cylinder 24 to slide. The hydraulic oil 27 slides through the through hole 26 on the piston 25 to the other end of the hydraulic cylinder 24, playing a shock-absorbing effect through the rebound of the first spring 22, and maintaining the stability of the vehicle body to prevent the vehicle from tipping over. When the first spring 22 rebounds, it drives the piston 25 to slide, and the hydraulic oil 27 slowly slides back to the initial position through the through hole 26. By adjusting the hydraulic oil 27, the rebound time of the first spring 22 can be adjusted, which can prevent the too-fast rebound from affecting the effect of vehicle adjustment. The aperture of the through hole 26 can be adjusted to achieve the effect of adjusting the rebound speed of the first spring 22. The hydraulic oil 27 in the hydraulic cylinder 24 is sealed by the fixed piston 13 and the sealing ring 29 to prevent leakage. Through the control of the first spring 22 and the hydraulic cylinder 24 during the turning of the off-road vehicle, the anti-rollover effect of the vehicle is improved.

[0037] In some preferred embodiments of the present invention, a sealing groove 28 is arranged on the side of the hydraulic cylinder 24 close to the sliding disk 23. A sealing ring 29 adapted to the sealing groove 28 is installed at the second end of the connecting rod 21.

[0038] Embodiment 2 Refer to Figure 5 and Figure 9, the auxiliary mechanism 3 is further defined. The auxiliary mechanism includes third connecting sleeves 31 arranged on both sides of the link shaft 4. One end of the third connecting sleeve 31 is rotatably connected to a second rotating shaft 32. The side of the second rotating shaft 32 is connected to the first end of a movable sleeve 33 provided with a cylindrical groove 34. The second end of the movable sleeve 33 is connected to an anti-roll bar 35. One side of the fixed block 6 is provided with a fixed rod 36. The anti-roll bar 35 is connected to the fixed rod 36. An activity groove 37 is provided in the fixed rod 36, and a second spring 38 is arranged in the activity groove 37; a connecting column 39 adapted to the activity groove 37 is arranged on the side of the anti-roll bar 35. One end of the second spring 38 is installed on the inner wall of the activity groove 37, and the other end of the second spring 38 is installed on the connecting column 39. When the off-road vehicle turns, due to the action of centrifugal force, one end of the anti-roll bar 35 is subjected to a certain extrusion and torsion, and the anti-roll bar 35 fixed at the other end counteracts the torsional force, generating a reverse torsion force, which is transmitted to the wheels through the suspension system, providing a reverse supporting force to the vehicle body, pulling one end of the vehicle straight, preventing the vehicle from tipping over. When the anti-roll bar 35 drives the second rotating shaft 32 to rotate, one end of the connecting column 39 slides in the activity groove 37, and the second spring 38 is stretched or compressed. The deformation and rebound of the second spring 38 drive the anti-roll bar 35 to return to its original position, helping the anti-roll bar 35 to return to its original position more easily, improving the maneuverability and stability of the vehicle, further enhancing the anti-roll effect of the vehicle, improving the applicability of the device, and the remaining features are the same as those in Embodiment 1.

[0039] Embodiment 3 As Figure 2 and 6 shown, a central bolt column 10 is installed in the leaf spring 1. Both ends of the central bolt column 10 penetrate through the leaf spring 1 and are respectively connected with a limiting plate 7. The limiting plates 7 are fixedly connected by a plurality of bolts 8, and nuts 9 are correspondingly arranged at one ends of the bolts 8; a second connecting sleeve 15 is arranged on the limiting plate 7 close to the link shaft 4. The second connecting sleeve 15 is connected to the link shaft 4. Both ends of the leaf spring 1 are provided with eyelets 14. The leaf spring 1 is installed at the bottom of the off-road vehicle through the eyelets 14 at both ends. When the operator controls the movement of the off-road vehicle, the vibrations of the vehicle are buffered by a plurality of leaf springs 1 at the bottom. When the vehicle travels on an uneven road surface, through the superimposed design among the plurality of leaf springs 1, a certain load is carried on the vehicle body, and the elastic force of the leaf spring 1 offsets the received vibration force, ensuring that the tires of the off-road vehicle are in full contact with the ground, reducing the vibrations transmitted to the vehicle body. The friction among the plurality of leaf springs 1 can also provide a damping effect, suppressing the rebound shock, ensuring the stability of the vehicle body, and enabling the operator to drive better. The remaining features are the same as those in Embodiment 1.

[0040] The working principle is as follows: The leaf spring 1 is installed at the bottom of the off-road vehicle through the eyelets 14 at both ends. When the operator controls the movement of the off-road vehicle, the vibrations of the vehicle are buffered by multiple leaf springs 1 at the bottom. When the vehicle travels on an uneven road surface, through the stacking design between multiple leaf springs 1, a certain load is borne on the vehicle body. The elastic force of the leaf spring 1 offsets the received vibration force, ensuring that the tires of the off-road vehicle are in full contact with the ground and reducing the vibration transmitted to the vehicle body. The friction between multiple leaf springs 1 can also provide a damping effect to suppress the rebound shock and ensure the stability of the vehicle body, enabling the operator to drive better. When the off-road vehicle needs to turn, one end of the vehicle body will tilt to a certain extent, and the bottom of the vehicle will squeeze one end of the top cover 12, simultaneously driving the first spring 22 to be compressed. The top cover 12 drives the hydraulic column 24 to slide, and then drives the piston 25 at one end of the connecting rod 21 to slide within the hydraulic column 24, mobilizing the hydraulic oil 27 within the hydraulic column 24 to slide. The hydraulic oil 27 slides through the perforation 26 on the piston 25 to the other end of the hydraulic column 24, achieving a shock-absorbing effect through the rebound of the first spring 22 and maintaining the stability of the vehicle body to prevent the vehicle from tipping over. When the first spring 22 rebounds, it drives the piston 25 to slide, and the hydraulic oil 27 slowly slides back to the initial position through the perforation 26. By adjusting the hydraulic oil 27, the rebound time of the first spring 22 can be adjusted to prevent the rebound from being too fast and affecting the vehicle adjustment effect. The aperture of the perforation 26 can be adjusted to achieve the effect of adjusting the rebound speed of the first spring 22. The hydraulic oil 27 within the hydraulic column 24 is sealed by the fixed piston 13 and the sealing ring 29 to prevent leakage. Through the control of the first spring 22 and the hydraulic column 24 during the turning of the off-road vehicle, the anti-rollover effect of the vehicle is improved. At the same time, when the off-road vehicle turns, due to the action of centrifugal force, one end of the anti-roll bar 35 is subjected to a certain extrusion and torsion, and the anti-roll bar 35 fixed at the other end counteracts the torsional force, generating a reverse torsional force, which is transmitted to the wheels through the suspension system, providing a reverse supporting force to the vehicle body and pulling one end of the vehicle back to prevent the vehicle from tipping over. When the anti-roll bar 35 drives the second rotating shaft 32 to rotate, one end of the connecting column 39 slides within the movable groove 37, causing the second spring 38 to be stretched or compressed. Through the deformation and rebound of the second spring 38, the anti-roll bar 35 is driven to return to its position, helping the anti-roll bar 35 to return to its position more easily, improving the maneuverability and stability of the vehicle, further enhancing the anti-rollover effect of the vehicle, and improving the applicability of the device.

[0041] The present invention provides a vehicle, including the above-mentioned off-road vehicle anti-rollover active hydraulic stability device.
