Description

Technical Field

[0001] This invention relates to the field of automotive vibration damping components, and more particularly to a cross-wheel passive conversion anti-torsion chassis and its application in vehicles. Background Technology

[0002] Currently, most vehicles use leaf springs, coil springs, hydraulic systems, and air suspensions for shock absorption. All these systems and suspensions have some excess constraint in their vertical travel. When a vehicle travels on uneven ground, the pressure from the higher wheels on the ground is uneven compared to the other wheels, causing torque to be generated in the chassis. When the ground elevation difference is significant, the lower wheels may become suspended and lose traction, resulting in significant bumps or tilting when attempting to pass over uneven surfaces, posing a risk of rollover. While some vehicles increase spring length to improve ground clearance, excessive spring travel leads to a relatively soft spring force, causing the vehicle to pitch forward and backward or tilt excessively during starting, braking, and turning, resulting in a loss of rigidity and stability, significantly reducing safety and speed. Summary of the Invention

[0003] To address the technical problems existing in the background art, this invention proposes a cross-wheel roller passive conversion anti-torsion chassis and its application in vehicles.

[0004] The present invention proposes a cross-roller passive conversion torque-eliminating chassis, comprising a chassis body, on which a front suspension and a rear suspension for mounting axles are mounted, and further comprising a cross-lift conversion longitudinal rocker arm, which is laterally rotatably mounted on the outside of the chassis body. One end of the cross-lift conversion longitudinal rocker arm is connected to the front suspension, and the other end of the cross-lift conversion longitudinal rocker arm is connected to the rear suspension. The cross-lift conversion longitudinal rocker arm is provided in two sets, one set of which is mounted on the first side of the chassis body, and the other set of which is laterally rotatably mounted on the second side of the chassis body, with the first side and the second side opposite to each other.

[0005] It also includes a cross-lifting and converting transverse rocker arm, which is longitudinally rotatably mounted on the chassis body. One end of the cross-lifting and converting transverse rocker arm supports the bottom of a set of cross-lifting and converting longitudinal rockers, and the other end of the cross-lifting and converting transverse rocker arm supports the bottom of another set of cross-lifting and converting longitudinal rockers.

[0006] The supporting cross-lift conversion lateral rocker arm is provided in two sets, and the two sets of supporting cross-lift conversion lateral rocker arms are distributed on both sides of the axis of rotation of the cross-lift conversion longitudinal rocker arm relative to the chassis body.

[0007] Preferably, it also includes a mounting shaft, which is longitudinally rotatably mounted on the chassis body, and the supporting cross lifting conversion lateral rocker arm is longitudinally rotatably mounted on the mounting shaft.

[0008] Preferably, it also includes a connecting block, on which the supporting cross lifting conversion lateral rocker arm is rotatably mounted laterally, and the mounting shaft is rotatably mounted longitudinally on the connecting block.

[0009] In some preferred embodiments, an intermediate shaft is also included, which is laterally rotatably mounted on the chassis body, and both sets of the cross lifting and conversion longitudinal rocker arms are rotatably mounted on the intermediate shaft.

[0010] Preferably, the chassis body has a limiting notch, and the supporting cross lifting conversion lateral rocker arm is located in the limiting notch and is used to limit the swing of the supporting cross lifting conversion lateral rocker arm in the vertical direction.

[0011] In some preferred embodiments, a connecting shaft is further included. The cross-lift conversion longitudinal rocker arm is fixed on the connecting shaft. The connecting shaft is laterally rotatably mounted on the chassis body. The chassis body has a support space in the middle. One end of the connecting shaft away from the cross-lift conversion longitudinal rocker arm extends into the support space. A longitudinal auxiliary rocker arm is fixed to one end of the connecting shaft away from the cross-lift conversion longitudinal rocker arm. The supporting cross-lift conversion lateral rocker arm supports the longitudinal auxiliary rocker arm.

[0012] Preferably, a longitudinal roller is mounted on the longitudinal rocker arm for cross-lift conversion, and a transverse roller is mounted on the transverse rocker arm for cross-lift conversion. The transverse roller is located below the longitudinal roller and supports the longitudinal roller. The longitudinal roller and the transverse roller are in point contact and form a cross roller support.

[0013] Preferably, the cross-lift conversion longitudinal rocker arm includes a mounting part, a connecting part, and a universal joint. The mounting part is laterally rotatably mounted on the chassis body, and the supporting cross-lift conversion lateral rocker arm supports the bottom of the mounting part. The connecting part is laterally rotatably mounted on the mounting part, and the universal joint is laterally rotatably mounted on the connecting part. An elastic telescopic member is installed between the connecting part and the mounting part, and the universal joint is connected to the front suspension or the rear suspension.

[0014] Preferably, the universal joint includes a connecting rod, one end of which is laterally rotatably mounted on the connecting part, and the other end of which is laterally rotatably connected to an upper universal ball connector. A vertical support rod is fixed on the upper universal ball connector, and a lower universal ball connector is fixed at the lower end of the vertical support rod. The lower universal ball connector is laterally rotatably connected to the front suspension or the rear suspension.

[0015] A vehicle comprising the cross-roller passive conversion torque-eliminating chassis described in any of the above technical solutions.

[0016] In this invention, the proposed cross-wheel roller passive conversion anti-torsion chassis and its application in vehicles enable the wheels to switch significantly in the vertical direction through the configuration of a cross-lift conversion longitudinal rocker arm and a supporting cross-lift conversion lateral rocker arm. When the vehicle travels on uneven ground with significant elevation differences, the wheels can rise and fall vertically with the undulations of the ground. The elevation of any one wheel has minimal impact on the grip of the other wheels, ensuring that the wheels are always in contact with the ground and preventing them from being suspended in the air. Even at high speeds, there will be no significant bumps. Furthermore, the configuration of the cross-lift conversion longitudinal rocker arm and the supporting cross-lift conversion lateral rocker arm ensures mutual restraint among the four wheels. Wheels on the same side of the chassis are connected by the cross-lift conversion longitudinal rocker arm, while wheels on different sides of the chassis are restrained by the supporting cross-lift conversion lateral rocker arm. This allows the wheel load to be passively transferred with the undulations of the uneven ground, resulting in a relatively uniform wheel load at different elevations. This ensures that the wheels always have relatively uniform support and grip on the ground, preventing any single wheel from sinking into the ground when the vehicle is traveling on desert or soft surfaces.

[0017] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] Example 1

[0029] like Figure 1-6 The diagram illustrates a cross-wheel passive conversion torsion-eliminating chassis and its application in a vehicle. It includes a chassis body 1, on which are mounted a front suspension 4 and a rear suspension 5 (the front suspension 4 is an independent suspension, and the rear suspension 5 is a non-independent suspension; the front suspension 4 and non-independent suspension 5 are merely schematic diagrams and not the focus of this invention; their specific structures should be understood by those skilled in the art as existing independent and non-independent suspension structures). It also includes a cross-lift conversion longitudinal rocker arm 2, which is laterally rotatably mounted on the outside of the chassis body 1. One end of the cross-lift conversion longitudinal rocker arm 2 is connected to the front suspension 4, and the other end is connected to the rear suspension 5. Specifically, the cross-lift conversion longitudinal rocker arm 2 is universally connected to the rear suspension 5 and the front suspension 4. Two sets of cross-lift conversion longitudinal rocker arms 2 are provided, with one set mounted on the first side of the chassis body 1 and the other set laterally rotatably mounted on the second side of the chassis body 1, with the first and second sides opposite each other.

[0030] Specifically, the two sets of cross-lifting and conversion longitudinal rocker arms 2 are defined as the first cross-lifting and conversion longitudinal rocker arm 2 and the second cross-lifting and conversion longitudinal rocker arm 2. The first cross-lifting and conversion longitudinal rocker arm 2 and the second cross-lifting and conversion longitudinal rocker arm 2 form two sets of cross-lifting and conversion longitudinal rocker arms 2. The first cross-lifting and conversion longitudinal rocker arm 2 is laterally rotatably mounted on one side of the chassis body 1, and the second cross-lifting and conversion longitudinal rocker arm 2 is laterally rotatably mounted on the other side of the chassis body 1. The first cross-lifting and conversion longitudinal rocker arm 2 and the second cross-lifting and conversion longitudinal rocker arm 2 are parallel to each other.

[0031] It also includes a cross-lifting and converting transverse rocker arm 6, which is longitudinally rotatably mounted on the chassis body 1. One end of the cross-lifting and converting transverse rocker arm 6 supports the bottom of a set of cross-lifting and converting longitudinal rocker arms 2, and the other end of the cross-lifting and converting transverse rocker arm 6 supports the bottom of another set of cross-lifting and converting longitudinal rocker arms 2.

[0032] The cross-lifting and conversion transverse rocker arm 6 is provided in two sets, and the two sets of cross-lifting and conversion transverse rocker arms 6 are distributed on both sides of the axis of rotation of the cross-lifting and conversion longitudinal rocker arm 2 relative to the chassis body 1.

[0033] Specifically, one set of supporting cross-lift conversion lateral rocker arms 6 is defined as the first supporting cross-lift conversion lateral rocker arm 6, and another set of supporting cross-lift conversion lateral rocker arms 6 is defined as the second supporting cross-lift conversion lateral rocker arm 6. The first supporting cross-lift conversion lateral rocker arm 6 and the second supporting cross-lift conversion lateral rocker arm 6 are arranged parallel to each other. The first supporting cross-lift conversion lateral rocker arm 6 supports the side of the first cross-lift conversion longitudinal rocker arm 2 and the second cross-lift conversion longitudinal rocker arm 2 near the front suspension 4. The second supporting cross-lift conversion lateral rocker arm 6 supports the side of the first cross-lift conversion longitudinal rocker arm 2 and the second cross-lift conversion longitudinal rocker arm 2 near the rear suspension 5. The first supporting cross-lift conversion lateral rocker arm 6 and the second supporting cross-lift conversion lateral rocker arm 6 are located on both sides of the cross-lift conversion longitudinal rocker arm 2 rotating relative to the chassis body 1. The axes of the first supporting cross-lift conversion lateral rocker arm 6 and the second supporting cross-lift conversion lateral rocker arm 6 are parallel to the axis of rotation of the cross-lift conversion longitudinal rocker arm 2 relative to the chassis body 1.

[0034] Furthermore, when the axes of the first support cross-lift conversion lateral rocker arm 6 and the second support cross-lift conversion lateral rocker arm 6 are on the same horizontal plane, the first cross-lift conversion longitudinal rocker arm 2 and the second cross-lift conversion longitudinal rocker arm 2 are in a horizontal state.

[0035] During operation, when one of the vehicle's front wheels is raised, assuming that the wheel corresponds to the front end of the first cross-lifting and lowering longitudinal rocker arm 2, the first cross-lifting and lowering longitudinal rocker arm 2 swings up and down, and the rear end of the first cross-lifting and lowering longitudinal rocker arm 2 presses down. Then, the second cross-lifting and lowering longitudinal rocker arm 2 presses down on the part of the second supporting cross-lifting and lowering transverse rocker arm 6 located behind the first cross-lifting and lowering longitudinal rocker arm 2. The second supporting cross-lifting and lowering transverse rocker arm 6 swings and presses the rear end of the second cross-lifting and lowering longitudinal rocker arm 2 to swing upward, thereby pressing the front end of the second cross-lifting and lowering longitudinal rocker arm 2 downward. Through the arrangement of the first cross-lifting and lowering longitudinal rocker arm 2, the second cross-lifting and lowering longitudinal rocker arm 2, the first supporting cross-lifting and lowering transverse rocker arm 6, and the second supporting cross-lifting and lowering transverse rocker arm 6, the two wheels located on the diagonal line are raised or lowered simultaneously.

[0036] Preferably, the cross-lifting and conversion horizontal rocker arm 6 is also equipped with a torsion spring to ensure that the cross-lifting and conversion horizontal rocker arm 6 is in a horizontal state when it is not compressed.

[0037] Preferably, it also includes a mounting shaft 7, which is longitudinally rotatably mounted on the chassis body 1, and the cross-lift conversion transverse rocker arm 6 is longitudinally rotatably mounted on the mounting shaft 7. This further increases the vibration reduction effect and ensures the cross-lift effect of the vehicle.

[0038] Preferably, it also includes a connecting block 8, on which the cross lifting conversion horizontal rocker arm 6 is rotatably mounted laterally, and the mounting shaft 7 is rotatably mounted longitudinally on the connecting block 8.

[0039] Preferably, it also includes an intermediate shaft 9, which is laterally rotatably mounted on the chassis body 1. Both sets of cross-lifting and converting longitudinal rocker arms 2 are rotatably mounted on the intermediate shaft 9. That is, the first cross-lifting and converting longitudinal rocker arm 2 and the second cross-lifting and converting longitudinal rocker arm 2 are coaxial with the axis of rotation relative to the chassis body 1, which further increases the overall vibration reduction effect.

[0040] In some preferred embodiments, the cross-lift conversion longitudinal rocker arm 2 includes a mounting part 20, a connecting part 21, and a universal joint 22. The mounting part 20 is laterally rotatably mounted on the chassis body 1, and the supporting cross-lift conversion transverse rocker arm 6 supports the bottom of the mounting part 20. The connecting part 21 is laterally rotatably mounted on the mounting part 20, and the universal joint 22 is laterally rotatably mounted on the connecting part 21. An elastic telescopic member 23 is installed between the connecting part 21 and the mounting part 20. The universal joint 22 is connected to the front suspension 4 or the rear suspension 5, increasing the service life of the cross-lift conversion longitudinal rocker arm 2.

[0041] Specifically, the elastic telescopic component 23 includes an elastic element, which is a spring 230. One end of the elastic element is fixed to the limiting component 232. The limiting component 232 has a sliding hole, and a sliding rod 231 is slidably installed in the sliding hole. A limiting plate 234 is fixed to the end of the sliding rod 231 away from the limiting component 232. The other end of the spring 230 is fixed to the limiting plate 234 and located outside the sliding rod 231. Specifically, the spring 230 is sleeved on the outside of the limiting component 232 and fixed to the end of the limiting component 232 away from the sliding rod 231. The limiting component 232 is laterally rotatably installed on the mounting part 20, and the limiting plate 234 is laterally rotatably installed on the connecting part 21 through a connector, further increasing the overall vibration reduction effect.

[0042] Preferably, the mounting part 20 and the supporting cross-lifting conversion horizontal rocker arm 6 are in point contact, which further increases the overall service life and the vibration reduction effect.

[0043] Preferably, a transverse roller 10 is rotatably mounted on the transverse rocker arm 6 supporting the cross lifting conversion, and a longitudinal roller 11 is rotatably mounted on the mounting part 20. The transverse roller 10 is located below the longitudinal roller 11 and supports the longitudinal roller 11. Specifically, a mounting groove is opened on the bottom surface of the mounting part 20, and a longitudinal shaft 12 is rotatably mounted on the mounting groove. The longitudinal roller 11 is rotatably mounted on the outside of the longitudinal shaft 12. The longitudinal roller 11 is coaxial with the longitudinal shaft 12. During the vibration reduction process, both the longitudinal roller 11 and the transverse roller 10 rotate relative to the chassis body 1, and the transverse roller moves relative to the longitudinal roller 11.

[0044] Preferably, the universal joint 22 includes a connecting rod 220. One end of the connecting rod 220 is laterally rotatably mounted on the connecting part 21, and the other end of the connecting rod 220 is laterally rotatably mounted with an upper universal ball connector 221. The upper universal ball connector 221 is fixed on the vertical support rod 222, and the lower end is fixed with a lower universal ball connector 223. The lower universal ball connector 223 is laterally rotatably connected to the front suspension 4 or the rear suspension 5. That is, the axis of rotation of the lower universal ball connector 223 relative to the upper suspension, the axis of rotation of the lower suspension relative to the upper universal ball connector 221 relative to the connecting rod 220, and the axis of rotation of the connecting part 21 relative to the mounting part 20 are all parallel. Furthermore, the aforementioned axes are parallel to the axis of rotation of the mounting part 20 relative to the chassis body 1. The connecting rod 220 is located above the front suspension 4 or the rear suspension 5, and the lower universal ball connector 223 is rotatably connected to the front suspension 4 and the rear suspension 5, thereby increasing the vibration reduction effect.

[0045] Preferably, the chassis body 1 has a limiting notch 3, and the supporting cross lifting conversion lateral rocker arm 6 is located in the limiting notch 3 and is used to limit the vertical swing of the supporting cross lifting conversion lateral rocker arm 6, so as to avoid the supporting cross lifting conversion lateral rocker arm 6 swinging too much relative to the chassis body 1.

[0046] Preferably, the limiting notch 3 is provided with an elastic element on the side opposite to the supporting cross lifting and conversion horizontal rocker arm 6, which can be a spring 230 plate.

[0047] The present invention has the following effects:

[0048] First, by setting up the longitudinal rocker arm 2 for cross-lift conversion and the lateral rocker arm 6 for cross-lift conversion, the suspension can achieve the function of cross-lift torsion reduction. The wheels can switch between each other significantly during the vertical lifting process. When the vehicle is driving on uneven ground with large height differences, the wheels can change vertically with the undulation of the ground. The lifting of any wheel has little impact on the grip of other wheels on the ground. That is, the wheels can always be in contact with the ground, avoiding the wheels from being suspended in the air. Even at high speeds, there will be no large bumps.

[0049] Secondly, the cross-lifting and conversion longitudinal rocker arm 2 and the supporting cross-lifting and conversion lateral rocker arm 6 ensure that the four wheels are mutually constrained. The wheels located on the same side of the chassis body 1 are connected by the cross-lifting and conversion longitudinal rocker arm 2, and the wheels located on different sides of the chassis body 1 are mutually constrained by the supporting cross-lifting and conversion lateral rocker arm 6. This allows the wheel load to be passively transferred to each other as the uneven ground undulates, so that the wheel load at high and low positions is basically uniform. This ensures that the wheels have relatively uniform support and grip on the ground, so that no single wheel will sink into the ground when the vehicle is driving on the desert or soft ground.

[0050] Secondly, the pivot point for the vehicle's lateral and vertical lifting conversion is between the two wheels. Therefore, when any wheel of the vehicle travels to a high position, within the range of the vertical lifting conversion height of the wheels, the vehicle body will not tilt excessively due to the increase in wheel height. This cross-lifting technology reduces the tilt angle of the vehicle body by half compared to the tilt angle of the existing vehicle chassis body 1, which means that this vehicle has higher comfort and stability when driving on uneven terrain.

[0051] Furthermore, this cross-wheel passive displacement conversion and torque reduction device can passively convert the load to each other with the undulations of uneven ground, so that when any single wheel rises over an obstacle, the wheel load will not gradually increase as the wheel rises. On the contrary, the load will gradually decrease, which means that any wheel can rise over an obstacle effortlessly.

[0052] Finally, this cross-shaped roller displacement conversion and torque reduction device makes the vehicle more flexible when driving on uneven ground. It reduces the power consumption of the vehicle caused by torque and the fatigue damage to the frame steel, extends the vehicle's range and service life, and improves the smoothness, comfort and safety of the vehicle when driving off-road.

[0053] Example 2

[0054] like Figure 7-8 As shown, the difference between this embodiment and the above embodiment is that the cross roller support position is located inside the chassis body: the above also includes a connecting shaft 13, the cross lifting conversion longitudinal rocker arm 2 is fixed on the connecting shaft 13, the connecting shaft 13 is laterally rotatably mounted on the chassis body 1, the chassis body 1 has a support space in the middle, one end of the connecting shaft 13 away from the cross lifting conversion longitudinal rocker arm 2 extends to the support space, and a longitudinal auxiliary rocker arm 14 is fixed to one end of the connecting shaft 13 away from the cross lifting conversion longitudinal rocker arm 2. The longitudinal auxiliary rocker arm 14 is perpendicular to the connecting shaft 13 and parallel to the cross lifting conversion longitudinal rocker arm 2, and the supporting cross lifting conversion transverse rocker arm 6 supports the longitudinal auxiliary rocker arm 14;

[0055] Specifically, the longitudinal auxiliary rocker arm 14 is cylindrical, and the longitudinal roller 11 is mounted on the longitudinal auxiliary rocker arm 14 for longitudinal rotation.

[0056] Two sets of cross-lifting and conversion transverse rocker arms 6 are mounted on the chassis via a mounting shaft 7. The mounting shaft 7 is mounted on the chassis with longitudinal rotation. During the cross-lifting process, since the two transverse rocker arms rotate in opposite directions relative to the mounting shaft 7, the vibration reduction effect is further increased and the chassis deformation is reduced.
