Definitions
- the present invention relates to a wheel, in particular a vehicle wheel.
- Various wheels are known for driving vehicles. Vehicles using known wheels have limited flotation.
- the cross-country ability of a vehicle is usually understood as its ability to move on low-quality roads and off the road network, as well as to overcome obstacles.
- caterpillar propellers are often used, containing a caterpillar belt moved by a driving wheel along a system of rollers.
- the track is elongated to provide a greater contact area with the surface on which it travels. This is due to the low specific pressure on this surface and, accordingly, high permeability.
- the disadvantage of the tracked mover is its low operational reliability due to the complexity of the design and rapid wear of the rubbing parts.
- Wheels with a variety of spoke configurations are also known. Typically, these wheels are designed to absorb shock and vibration when the vehicle is moving. Such solutions practically do not bring improvements in the cross-country ability of the vehicle.
- the spoke parts attached to the rim are telescopic.
- the task of the known wheel is to absorb shock and vibration during vehicle movement. At the same time, the passability of such a vehicle remains limited.
- there is an obvious need for further improvement of the known wheels in particular for improving the passability of vehicles using such wheels.
- the object of the present invention is to provide a wheel that provides increased permeability to the vehicle in which it is used.
- each spoke consists of at least two parts connected to each other with the ability to rotate with respect to each other, and one of these parts is connected with the possibility of rotation to the hub , and the other is connected with the possibility of rotation to the rim, while the rim has a limited flexibility in the plane of the wheel, and the distance between the wheel axis and the rim is variable around the wheel circumference.
- the proposed wheel under the action of its own weight and the weight of a vehicle using such a wheel, acquires an elongated shape similar to that of a caterpillar track.
- curved, essentially semicircular, sections of the rim are located in the front and rear parts of the wheel in the direction of travel.
- the curvature of the rim of such a wheel in its upper and lower parts is usually close to zero, i.e. the wheel rim has substantially straight sections at these locations.
- the proposed wheel provides a technical result, which consists in increasing the permeability.
- Parts of the spoke can be connected to each other with the possibility of limited rotation with respect to each other. This can be achieved, for example, by installing a stop bar on one of the spoke parts. In this case, when the spoke portions are pivoted with respect to each other after the predetermined pivot angle has been reached, further pivoting is prevented by the abutment of the other spoke portion against the stopper bar, as described in more detail below. Due to the limitation of the rotation of the spoke parts with respect to each other, the structure of the spoke and rim parts acquires rigidity in those spoke positions in which the spoke parts are rotated with respect to each other at a minimum predetermined angle. Thus, the wheel in this version has increased strength. It should be obvious to a person skilled in the art that limiting the rotation of the spoke parts with respect to each other can be achieved in other ways, for example, using a hinge of an appropriate design with an integrated stop.
- One end of the rod can be pivotally attached to each spoke at the junction of its parts, and the other end of this rod can be pivotally attached to the rim at a certain circumferential distance from the point of attachment of the spoke to the rim. This solution increases the stability of the wheel during rotation.
- the rod and the spoke portion attached to the rim are identical and form a Y-configuration with the spoke portion attached to the hub.
- the distance between the points of attachment of the rod and the spoke to the rim can be equal to the total length of the rod and the part of the spoke attached to the rim.
- the end of the spoke and the corresponding rod attached to the rim diverge to the maximum distance, essentially forming a flat angle. Due to the impossibility of increasing this distance, further rotation of the spoke parts in relation to each other is not possible, so that other limiting means, such as stop bars, become unnecessary.
- the spoke parts and the rod are mainly in tension, so the needles and rods can be flexible.
- the end of the spoke and the corresponding rod attached to the rim converge again and, accordingly, the angle between them decreases.
- the spoke parts and / or the rod can be made in the form of rods or elongated plates, and the joints of these rods or elongated plates with the rim, hub and between themselves can be hinged or flexible.
- the ability of the spokes and rods to withstand compressive loads is absent, because Despite the rigidity of the rods themselves or the elongated plates, the hinges provide flexibility and prevent the spoke with the rod attached to it from forming a rigid structure.
- the rim in the proposed wheel can be made of segments, with each two adjacent segments connected to each other with the possibility of limited rotation with respect to each other. Thus, limited wheel compliance is ensured.
- the rim segments can be pivotally connected. Also, the rim segments can be connected flexibly, for example by means of flexible links.
- the angle of rotation of each two adjacent segments can be limited, for example, in the range from - 360 / N to 360 / N, where N is a number from 10 to the number of rim segments.
- N is a number from 10 to the number of rim segments.
- the hub of the proposed wheel can be made with the possibility of mounting the wheel on a standard vehicle axis, and for this purpose, corresponding holes can be made in the hub.
- An embodiment of the present invention is also possible, in which the proposed wheel is mounted on a standard vehicle wheel.
- the standard vehicle wheel is entirely used as a hub, or the proposed wheel is rigidly attached to the standard vehicle wheel.
- This solution allows the proposed wheel to be used as an attachment in those situations when it is required to increase the cross-country ability of a vehicle, for example, when leaving the road on unstable ground or snow.
- the rim is continuous, and its limited flexibility is provided due to its structure and / or the material from which it is made.
- Limited flexibility of the rim can also be achieved when the rim is made of at least one flexible tape on which at least At least on one side, there are persistent protrusions of such a configuration that when a given curvature of the tape is reached, they, closing, prevent further bending of the tape.
- the wheel When the wheel is wide, i.e. has a certain length in the axial direction, it may contain an additional set of spokes so that the two sets of spokes are axially spaced apart from each other.
- the latter can contain an additional set of spokes, while the attachment point of each spoke to the hub and the attachment point of this spoke to the rim are axially spaced from each other.
- FIG. 1 shows an example of an implementation of a wheel according to the present invention.
- FIG. 2 is a schematic perspective view of a portion of the wheel rim of FIG. 1.
- FIG. 3 schematically shows another example of a Y-spoke wheel.
- FIG. 4 is a schematic illustration of an embodiment of a rim with limited flexibility.
- FIG. 5 schematically illustrates the operation of the inner abutment tabs of the rim of FIG. 4.
- FIG. 5 schematically illustrates the operation of the outer abutment lips of the rim of FIG. 4.
- FIG. 6 schematically shows the proposed wheel mounted on a standard vehicle wheel, which is used as a hub.
- FIG. 1 schematically shows one of the embodiments of the wheel 100 according to the present invention, containing the hub 1 and the rim 2 of segments 3 made in the form of plates of different thickness with rounded ends, pivotally connected to each other like links of a bicycle chain.
- thinner segments alternate with thicker ones, with the ends of the thinner segments located in the gaps at the ends of the thicker segments.
- the axis 4 Through the overlapping ends of the adjacent segments are passed by the axis 4, which provides the possibility of their articulation with respect to each other.
- Each two adjacent segments 3 have a limited rotation angle ranging from (- 360 / N) to (360 / N), where N is a number from 10 to the number of segments 3 forming rim 2.
- Spokes 5 are connected to the hub 1 at one end with the possibility of pivoting on the hinge 7.
- the other end of the spokes 5 are each attached to the rim 2 with the possibility of pivoting on the hinge 6.
- Each spoke 5 consists of at least two parts: 5.1, connected to the hub, and 5.2 attached to the rim. Parts 5.1, 5.2 of the spokes are connected to each other with the possibility of pivoting on the hinge 8. At the end of the part 5.1 of the spokes near the hinge there is a stop bar 9.
- parts 5.1, 5.2 of the spokes are made in the form of elongated plates.
- parts of the spokes can be made in another way, for example, in the form of rods.
- Other embodiments of the spokes are possible and should be obvious to a person skilled in the art.
- the structure of the spoke and rim parts acquires rigidity in those spoke positions in which parts of the spoke are rotated relative to each other by the minimum specified angle.
- the wheel resists well the loads directed from top to bottom, i.e. has a high carrying capacity.
- FIG. 3 schematically shows another embodiment of the proposed wheel.
- one end is pivotally attached to a rod 10, the other end of which is pivotally connected to the rim 2 at a certain circumferential distance from the point of attachment of the said spoke 5.
- FIG. 3 shows only two spokes 5, the rest are not shown for clarity.
- the linkage J0 and the spoke section 5.2 attached to the rim are identical and form a Y-configuration with the spoke section 5.1 attached to the hub.
- a wheel made in this way maintains an elongated shape with high stability.
- one spoke 5 with a rod 10 attached to it extends from the hub 1 towards the curved portion of the side part of the wheel.
- Part 5.2 of this spoke, attached to the rim, and the rod 10 diverge at a minimum angle to achieve the maximum total length of the spoke in accordance with the maximum distance from hub 1 to rim 2.
- the second spoke 5 with rod 10 attached to it passes from hub 1 to the upper section parts of a wheel that is essentially straight. In this position, the angle between part 5.2 of this spoke and the rod 10 is increased to its maximum, reaching the minimum overall spoke length in accordance with the minimum distance from the hub to the rim.
- spokes and rods can be made not only rigid, in the form of elongated plates or rods, but also flexible, for example, in the form of cables.
- the spoke parts there is no need for articulated connection of the spoke parts with the hub, with the rim and with each other, because the possibility of relative rotation of parts of the spokes and rods in relation to each other, as well as to the hub and rim, is realized due to their flexibility.
- the rim of the proposed wheel can be made of a flexible tape 1 1, on which at least one side, in this example, on both sides, stop protrusions 13, 14 of such a configuration are placed at intervals that when a given curvature of the tape is reached, they are closed , prevent further bending of the tape.
- the belt 1 1 is made of a strong, flexible, essentially inextensible material, for example, glass fiber, enclosed in an elastic shell 12, for example of elastomer, and the abutment protrusions 13, 14 are made of a rigid material.
- the outer abutment protrusions 14 must be resistant to wear. As shown in FIG.
- the inner abutment protrusions 13 can be made trapezoidal.
- FIG. 7 schematically shows another embodiment of a wheel according to the present invention. As in FIG. 3, FIG. 7 shows only two spokes 5, the rest are not shown for clarity.
- the structure of the wheel 200 shown in FIG. 7 differs from the above-described structure of the wheel 100 shown in FIG. 1, in that the standard vehicle wheel 15 is used as the hub 1, to which the spokes 5 are connected at one end thereof. For this, the corresponding fastening means are installed on the wheel.
