Description

Technical Field

[0001] This invention belongs to the field of vehicle technology, and more specifically, relates to a wheel, a vehicle, and a method for adjusting the wheel width and track width of the vehicle. Background Technology

[0002] The relevant vehicle has an adjustment component between the two wheels located in the width direction of the vehicle. By adjusting the component, the wheel is pushed outward to make the two wheels move away from each other, or pulled inward to make the two wheels move closer to each other, so as to adjust the distance between the two wheels and thus change the required road width of the two wheels.

[0003] However, the vehicle can only adjust the road width required by the two wheels, while the wheel width cannot be adjusted. Summary of the Invention

[0004] In view of this, the present invention provides a vehicle with an adjustable wheel track to solve the technical problem that while the required road width for two wheels can be adjusted, the width of a single wheel cannot be adjusted.

[0005] The technical solution of this invention is implemented as follows:

[0006] This invention provides a wheel, comprising: a hub for connecting a vehicle body; a rim surrounding the hub; an outer side of the rim for mounting a tire; and an adjusting assembly disposed between the hub and the rim, and capable of telescoping; a first distance between the hub and the rim in the width direction of the rim increases as the adjusting assembly extends and decreases as the adjusting assembly shortens.

[0007] In some embodiments, the adjustment assembly includes: a plurality of hydraulic cylinders, one end of which is hinged to a wheel hub and the other end of which is hinged to a wheel rim in the extension direction; and the plurality of hydraulic cylinders are arranged around the width direction and within a conical surface; wherein the apex angle of the conical surface decreases as the first distance increases and increases as the first distance decreases.

[0008] In some embodiments, the apex angle α of the conical surface is greater than or equal to 80 degrees and less than or equal to 160 degrees.

[0009] In some embodiments, the piston rod of the hydraulic cylinder is provided with a first universal joint ball joint, which is hinged to the wheel rim; the cylinder body of the hydraulic cylinder is provided with a second universal joint ball joint, which is hinged to the wheel hub.

[0010] In some embodiments, the first hinge point where the first universal joint ball joint head is hinged to the rim is near the outer side of the rim, and the second hinge point where the second universal joint ball joint head is hinged to the hub is near the inner side of the rim.

[0011] In some embodiments, the adjustment assembly further includes a connecting pipe comprising a plurality of retractable pipe segments, the pipe segments and the hydraulic cylinder being arranged alternately in sequence in the circumferential direction of the rim, the interior of the pipe segments being in communication with the interior of the hydraulic chamber of the hydraulic cylinder.

[0012] In some embodiments, the regulating assembly further includes: a controller electrically connected to the oil pump of the regulating assembly to control the steering and switching of the oil pump; and a monitor electrically connected to the controller to obtain information about the road surface ahead of the vehicle.

[0013] This invention also provides a vehicle, including: a wheel; and a drive shaft connected to the wheel hub to transmit torque to the wheel hub.

[0014] This invention also provides a method for adjusting the wheel width and track width of a vehicle, comprising the following steps: S1, obtaining the road conditions in front of the vehicle; S2, controlling the direction and switch of the oil pump according to the obtained road conditions.

[0015] In some embodiments, step S2 includes: S21, if the road surface condition is smooth or the road surface is widened, extract the liquid from the hydraulic cylinder; S22, if the road surface condition is uneven or the road surface is narrowed, inject liquid into the hydraulic cylinder.

[0016] The wheel of this invention includes a hub, a rim, and an adjustment assembly. The hub connects to the vehicle body; the rim surrounds the hub; the outer side of the rim is used to mount a tire; the adjustment assembly is disposed between the hub and the rim and is telescopic; a first distance between the hub and the rim in the width direction of the rim increases as the adjustment assembly extends and decreases as the adjustment assembly shortens. By disposing the adjustment assembly between the hub and the rim, the telescopic movement of the adjustment assembly causes a change in the first distance between the hub and the rim in the width direction of the rim, thereby adjusting the width of the wheel. Because the wheel width changes, the outer surface of the wheel moves in the width direction, changing the distance between the outer surfaces of the two wheels, thus changing the required road width for both wheels in the width direction. Therefore, the wheel of this invention can adjust not only the width of a single wheel but also the required road width for both wheels. Attached Figure Description

[0031] This invention provides a wheel. This wheel can be applied to vehicles such as automobiles, electric vehicles, and bicycles; that is, the application scenario of this wheel does not limit its structure. However, for ease of explanation, all embodiments of this invention are described using the application of the wheel to an automobile as an example.

[0032] like Figure 1 As shown, the wheel 1 includes a hub 11 and a rim 12. The hub 11 is used to connect to the vehicle body; specifically, the hub 11 can be used to connect to the crossbeam of the vehicle body to form a driven wheel; the hub 11 can also be used to connect to the drive shaft of the vehicle body to form a drive wheel. The outer side of the rim 12 is used to mount the tire 13; the rim 12 is commonly referred to as a steel rim, that is, the rim 12 is an annular ring with an inner diameter and an outer diameter, so the outer side of the rim 12 can be understood as the side close to the outer diameter of the rim 12. The tire 13 used to mount the outer side of the rim 12 can be a combination of an inner tube and an outer tire, or it can be a tubeless tire (i.e., a tire without a tube), but no matter what kind of tire 13 is mounted on the outer side of the rim 12, the tire 13 and the rim 12 are fixed together, that is, the tire 13 and the rim 12 can be regarded as a whole; thus, the movement of the rim 12 will inevitably drive the movement of the tire 13.

[0033] like Figure 1 As shown, the rim 12 surrounds the hub 11. Specifically, the rim 12 and the hub 11 are spaced apart in the radial direction. Since the shapes of the rim 12 and the hub 11 are fixed, the radial spacing between them is constant. This radial direction is exemplarily represented by multiple dashed lines b in the figure.

[0034] like Figure 1As shown, the adjusting component 14 is disposed between the hub 11 and the rim 12, that is, one end of the adjusting component 14 is connected to the hub 11, and the other end of the adjusting component 14 is connected to the rim 12. Thus, the adjusting component 14 provides support between the rim 12 and the hub 11. The adjusting component 14 of the wheel 1 in this embodiment is similar to the corresponding wheel spoke, but the adjusting component 14 in this embodiment is telescopic (i.e., the length of the adjusting component is adjustable), while the length of the corresponding wheel spoke is fixed. Furthermore, the first distance between the hub 11 and the rim 12 in this embodiment (this first distance is the first distance between the rim 12 and the hub 11 in the width direction of the rim 12, the width direction is represented by the dashed line a in the figure, and the first distance is identified by d in the figure) is adjustable; specifically, as shown... Figure 2 As shown ( Figure 2 To facilitate demonstration of the extension and retraction of the adjustment component 14 (the wheel rim is not shown), when the adjustment component 14 extends, the first distance d between the hub 11 and the wheel rim increases; for example... Figure 3 As shown ( Figure 3 (The wheel rim is not shown to facilitate demonstration of the extension and retraction of the adjustment component 14.) If the adjustment component 14 is shortened, the first distance d between the hub 11 and the rim decreases. However, the first distance between the hub and the rim of the relevant wheel in the width direction of the rim remains constant.

[0035] like Figures 1 to 3 As shown, the principle of adjusting the width of a single wheel 1 in this embodiment of the invention is as follows: When the adjusting component 14 extends, the first distance d between the hub 11 and the rim 12 increases, causing the hub 11 and the rim 12 to move closer to each other in the width direction, thus narrowing the width of the wheel 1. When the adjusting component 14 shortens, the first distance d between the hub 11 and the rim 12 decreases, causing the hub 11 and the rim 12 to move further apart in the width direction, thus widening the width of the wheel 1.

[0036] like Figure 1 As shown, the principle of adjusting the required road width of the two wheels 1 in this embodiment of the invention is as follows: during the process of widening or narrowing a single wheel 1, the outer side of the single wheel 1 (the outer side can be understood as a vertical side exposed to the outside world and easily observed after the wheel is installed on the vehicle body, marked with M in the figure) moves in the width direction, and the distance between the outer sides of the two wheels 1 in the width direction changes, so that the required road width of the two wheels 1 changes.

[0037] The wheel of this invention includes a hub, a rim, and an adjustment assembly. The hub connects to the vehicle body; the rim surrounds the hub; the outer side of the rim is used to mount a tire; the adjustment assembly is disposed between the hub and the rim and is telescopic; a first distance between the hub and the rim in the width direction of the rim increases as the adjustment assembly extends and decreases as the adjustment assembly shortens. By disposing the adjustment assembly between the hub and the rim, the telescopic movement of the adjustment assembly causes a change in the first distance between the hub and the rim in the width direction of the rim, thereby adjusting the width of the wheel. Because the wheel width changes, the outer surface of the wheel moves in the width direction, changing the distance between the outer surfaces of the two wheels, thus changing the required road width for both wheels in the width direction. Therefore, the wheel of this invention can adjust not only the width of a single wheel but also the required road width for both wheels.

[0038] Regarding the application scenarios of this wheel adjustment, the following three adjustment methods can be referenced, but are not limited to: First, when changing tires, the width formed by the rim and hub of a single wheel can be adjusted to match the width of the tire to be replaced; this expands the tire's compatibility range, facilitating wheel maintenance and replacement. Second, before traversing uneven road surfaces, the two wheels can be moved further apart to improve vehicle stability. Third, when traversing narrow roads, the two wheels can be moved closer together to facilitate passage.

[0039] In some embodiments, such as Figure 2 and Figure 3 As shown, the adjustment assembly 14 includes a plurality of hydraulic cylinders 141. One end of the hydraulic cylinder 141 in the extension / retraction direction is hinged to the hub 11, and the other end is hinged to the rim 12. Exemplarily, the piston rod 1411 of the hydraulic cylinder 141 is hinged to the rim 12, and the cylinder body 1412 of the hydraulic cylinder 141 is hinged to the hub 11. The plurality of hydraulic cylinders 141 are arranged in a conical surface (shown as a dashed triangle in the figure) about the width direction. The apex angle α of the conical surface decreases as the first distance increases and increases as the first distance decreases.

[0040] It is understandable that, since the shapes of the rim 12 and the hub 11 are constant, if the extension and retraction direction of the hydraulic cylinder 141 is perpendicular to the width direction, then the hydraulic cylinder 141 cannot extend or shorten. Because the outer diameters of the rim 12 and the hub 11 are different, there must be a radial misalignment between them, meaning that the hydraulic cylinder 141 connecting the rim 12 and the hub 11 cannot extend or retract solely along the width direction.

[0041] Therefore, in this embodiment of the invention, by arranging the hydraulic cylinders within a conical surface, the hydraulic cylinders are able to extend and retract. Since the apex angle of the conical surface is greater than 0 degrees and less than 180 degrees, the hydraulic cylinders will inevitably exert a force along the width direction during the extension and retraction process. This force in the width direction causes the rim and hub to move closer together or further apart.

[0042] In some embodiments, such as Figures 1 to 3 As shown, the hydraulic cylinders 141 are evenly arranged in the circumferential direction. The hub 11 is located at the center of the rim 12, and the multiple hydraulic cylinders 141 are evenly arranged around the hub 11 in the circumferential direction (the circumferential direction is the circumferential direction around the radial direction b, which is represented by the dashed line c in the figure). In this way, the rim and hub are evenly stressed in the circumferential direction, thereby reducing the risk of rim and hub misalignment during the adjustment of the first distance.

[0043] In some embodiments, such as Figure 2 and Figure 3 As shown, the vertex angle α of the cone is greater than or equal to 80 degrees and less than or equal to 160 degrees. Figure 4 and Figure 5 As shown, when the hydraulic cylinder 141 is considered as a line segment along the extension and retraction direction of the hydraulic cylinder 141, the angle β between the hydraulic cylinder 141 and the width direction is half of α.

[0044] like Figure 4 and Figure 5 As shown, the forces exerted by the hydraulic cylinder 141 on the hub 11 and the rim 12 are equal in magnitude and opposite in direction. For simplicity, this embodiment of the invention will describe the force exerted by the hydraulic cylinder 141 on the rim 12. The force F exerted by the hydraulic cylinder 141 on the rim 12 can be decomposed into a force F1 in the width direction and a force F2 in the radial direction. F1 causes the rim 12 to move closer to or further away from the hub 11, and F2 enables the rim 12 to bear the weight of the vehicle body (it can also be understood that F2 keeps the rim 12 and the hub 11 radially stable). Assuming that the force exerted by the hydraulic cylinder 141 on the rim 12 is F, when the included angle β is equal to 40 degrees, as... Figure 4 As shown, the hydraulic cylinder 141 applies a force in the width direction to the rim 12. The hydraulic cylinder 141 applies a radial component of force to the rim 12. When the included angle β equals 80 degrees, such as Figure 5 As shown, the hydraulic cylinder 141 applies a force in the width direction to the rim 12. The hydraulic cylinder 141 applies a radial component of force to the rim 12. Therefore, the magnitudes of F1 and F2 are closely related to the included angle β, and the range of variation of this included angle β can be affected by multiple factors, including at least the outer diameter of the hub 11, the inner diameter of the rim 12, the extension and retraction of the hydraulic cylinder 141, and the specifications of the hydraulic cylinder 141. Therefore, in order for the hydraulic cylinder 141 to both push the rim 12 and / or the hub 11 and bear the weight of the vehicle body, the included angle β must be greater than or equal to 40 degrees and less than or equal to 80 degrees. Correspondingly, the apex angle α of the conical surface must be greater than or equal to 80 degrees and less than or equal to 160 degrees.

[0045] In this embodiment of the invention, by setting the apex angle of the conical surface to be greater than or equal to 80 degrees and less than or equal to 160 degrees, the hydraulic cylinder can both adjust the first distance between the wheel hub and the rim and stably support the wheel hub and the rim.

[0046] In some embodiments, such as Figure 4 and Figure 5 As shown, the piston rod 1411 is provided with a first universal joint ball head 14111, which is hinged to the rim 12; the cylinder body 1412 is provided with a second universal joint ball head 14121, which is hinged to the hub 11. In a specific implementation, the hub 11 and the rim 12 are respectively provided with spherical grooves adapted to the first universal joint ball head 14111 and the second universal joint ball head 14121, which extend into their respective spherical grooves. This embodiment of the invention, through the provision of two universal joint ball heads and two spherical grooves, makes the two ends of the hydraulic cylinder spherically hinged, facilitating the hydraulic cylinder to rotate both in the width direction and radially during extension and retraction, ensuring flexible rotation and preventing jamming.

[0047] In some embodiments, such as Figure 4 and Figure 5 As shown, the first hinge point Q1 where the first universal joint ball joint 14111 is hinged to the rim 12 is close to the outer side of the rim 12, and the second hinge point Q2 where the second universal joint ball joint 14121 is hinged to the hub 11 is close to the inner side of the rim 12. If the wheel is mounted on the vehicle body, the inner side of the rim 12 is not easily observed from the outer side of the vehicle, while the outer side of the rim 12 is easily observed from the outer side of the vehicle; that is, the inner and outer sides of the rim 12 correspond to the inner and outer sides of the vehicle.

[0048] In this embodiment of the invention, by placing the first hinge point near the outer side of the rim and the second hinge point near the inner side of the rim, the wheel widens and the two wheels move further apart in the width direction when the hydraulic cylinder extends; conversely, when the hydraulic cylinder retracts, the wheel narrows and the two wheels move closer together in the width direction. Thus, the widening of a single wheel is consistent with the widening of the distance between the two wheels, and the narrowing of a single wheel is consistent with the indirect narrowing of the two wheels, conforming to human thinking habits and improving the user experience.

[0049] Furthermore, the positioning of the first and second hinge points allows the hydraulic cylinder to be concealed from extending out of the wheel, reducing the risk of collision with the outside world.

[0050] In some embodiments, such as Figure 7 As shown, the hydraulic cylinder 141 may be provided with multiple piston rods 1411, and the extension and retraction directions of the multiple piston rods 1411 are consistent. For example, Figure 7 The hydraulic cylinder 141 has two piston rods arranged sequentially along its extension and retraction direction. Therefore, the extension and retraction of this hydraulic cylinder 141 are twice that of a hydraulic cylinder 141 with only one piston rod. By using multiple piston rods, this embodiment of the invention increases the extension or retraction of the hydraulic cylinder, thus doubling the adjustment range of the first distance of the wheel.

[0051] In some embodiments, such as Figure 7 and Figure 8 As shown, the regulating component 14 also includes a connecting pipe 142. (As indicated...) Figure 7 As shown, the connecting pipe 142 can be a complete ring, and the interior of the connecting pipe 142 communicates with the interior of the hydraulic chambers of each hydraulic cylinder 141. Figure 8 As shown, the connecting pipe 142 includes multiple retractable pipe sections 1421, which are arranged alternately with the hydraulic cylinder 141 in the circumferential direction of the rim 12. The interior of the pipe section 1421 is connected to the interior of the hydraulic chamber of the hydraulic cylinder 141. In a specific implementation, an oil pump is connected to the pipeline between the connecting pipe 142 and the oil tank 143. The oil pump can allow oil in the oil tank 143 to enter the connecting pipe 142 and then enter the hydraulic cylinder 141, and can also allow oil in the hydraulic cylinder 141 to enter the oil tank 143 through the connecting pipe 142.

[0052] The present invention, through the arrangement of the connecting pipe, facilitates the simultaneous extension and retraction of each hydraulic cylinder, thereby distributing the force on the rim and hub evenly in the circumferential direction, which is beneficial for the movement of the hub and hub in the width direction, and reduces the risk of hub and rim misalignment.

[0053] In some embodiments, the adjustment assembly 14 further includes a controller (not shown) and a monitor (not shown). The controller is electrically connected to the oil pump to control the direction and switching of the oil pump. The monitor is electrically connected to the controller to obtain the road conditions in front of the vehicle. The monitor can be a camera, radar, or other device capable of detecting road conditions. For example, after the monitor obtains the road conditions, it sends information to the controller. The controller determines that the wheel width needs to be increased based on the road conditions and turns on the oil pump, causing it to rotate forward, increasing the hydraulic volume in the hydraulic chamber of the hydraulic cylinder. After the wheel width adjustment is complete, the oil pump is turned off. This embodiment of the invention, through the setting of the controller and monitor, can conveniently obtain road conditions and enable the wheels to automatically adjust their width based on the road conditions.

[0054] This invention also provides a vehicle. The vehicle includes a driveshaft 2 and, as shown in the figure... Figures 1 to 8 The wheel 1 is shown. The drive shaft 2 is connected to the wheel hub 11 to transmit torque to the hub 11. This torque is transmitted to the rim 12 and tire 13 through the adjusting assembly 14, thereby causing the tire 13 to rotate and the vehicle to move forward.

[0055] This invention also provides a method for adjusting the wheel width and track width of a vehicle. The method includes the following steps: S1, acquiring the road conditions ahead of the vehicle; specifically, this can be achieved through devices such as cameras or radar. S2, controlling the steering and switching of an oil pump based on the acquired road conditions; the oil pump is controlled by a controller that receives road information. Thus, the wheel width and track width are adjusted according to the road conditions.

[0056] In some embodiments, step S2 includes: S21, if the road surface condition is flat or the road surface is widened, extract the liquid from the hydraulic cylinder; S22, if the road surface condition is uneven or the road surface is narrowed, inject liquid into the hydraulic cylinder.

[0057] For example, the monitor acquires road surface data in front of the vehicle and sends it to the controller. After receiving the data, the controller compares it with a preset value. If the road surface is determined to be smooth, the controller controls the oil pump to rotate in the reverse direction to extract liquid from the hydraulic cylinder, thereby shortening the hydraulic cylinder and reducing the first distance between the rim and the hub, ultimately narrowing the wheel. If the road surface is determined to be uneven, the controller controls the oil pump to rotate in the forward direction and inject liquid into the hydraulic cylinder, thereby extending the hydraulic cylinder and increasing the first distance between the rim and the hub, ultimately widening the wheel.

[0058] When wheels become wider, the distance between the outer sides of the two wheels increases, meaning the required road width for the two wheels increases, or the wheelbase increases. Conversely, when wheels become narrower, the distance between the outer sides of the two wheels decreases, meaning the required road width for the two wheels decreases, or the wheelbase decreases.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
