Description

VEHICLE AND VEHICLE VEHICLE ELEMENT

FIELD OF THE INVENTION The invention relates to transport engineering, in particular, to support and running elements of cross-country ability. BACKGROUND

Known support elements, including a cylinder with a screw located on its outer surface. The auger support elements rotate around their longitudinal axes, the augers cut into the group and provide extremely high adhesion with it, which ensures a very significant cross-country ability of a vehicle equipped with an action support elements. Such support elements are disclosed in the patent.

GB 2300842 A. This technical solution is taken as a prototype of the present invention.

However, this device has a number of significant: disadvantages.

First of all, it should be noted that it is intended mainly for moving off-road. In the case of movement on the road, the road surface is destroyed by a screw. Thus, the scope of use of the prototype is very limited. It should also be noted that the vehicle can only move in the direction of the longitudinal axis of the cylinders with axial elements, which makes it very small maneuverability. Therefore, the vehicle has to be transported on roads on special platforms. The intrinsic speed of the known supporting-running element is in any case small. If there is a need to move off-road, on dense stable soil, the device moves at the same low speed as on loose, unstable. It should also be noted that in case of failure of one of the two cylinders with screw elements, the vehicle loses the ability to move in a straight line and can only move in a circle, which causes its low survivability.

However, from the patent RU 2229997 a screw supporting-running element is known made of separate parts provided with axes, and holes are made in the cylinder, into which axes of the parts of the gansky are inserted with the possibility of rotation item. In addition, from the patent RU 2229998 known screw supporting-running element made of separate parts, which are installed with the possibility of extension from the screw slot made in the body of the cylinder. The ability to rotate these individual parts is provided by a mechanical drive or any known drive. Thus, due to the fact that the screw blade of the screw is divided into independent parts, this supporting-running element can operate in the screw mode, when the segments form a rigid screw blade, and in the rolling mode, when the segments are rotated about its axis. In addition, the above devices have amphibious properties. The disadvantages of these inventions are the complexity and a large number of parts of the structure, which indicates the unreliability of the structure, and therefore the complex and expensive process of its manufacture. To move along the road surface, some parts of the auger blades are equipped with rubber pads, which, however, do not help to avoid damage to the road surface. The present invention is based on the solution of the problem of reducing the cost of technology for the manufacture and maintenance of a vehicle, including a screw support element; ensuring a simple and lightweight construction of the vehicle as a whole, and in particular, of the supporting element; providing increased maneuverability and speed at low energy costs; providing the ability to move the vehicle both off-road and on the road surface, without causing the latter significant harm, while absorbing dynamic loads when moving on an uneven surface of the ground or road surface; providing a quick transition of the supporting-traveling element from the r-gear mode to the rolling mode; survivability in the event of failure of the parts of the running gear.

SUMMARY OF THE INVENTION According to the invention, this problem is achieved by creating a support element of a vehicle, including a peg, having a helical blade, in which there is a tank in the inter-turn space, made with the possibility of expansion upon receipt of the working substance and narrowing upon exit of the working substance.

The working substance that enters the reservoir may be air, gas or liquid. An expanded tank containing air as a working substance provides good amphibious properties of the supporting element. This makes it possible to move the vehicle off-road, on a flat and uneven road surface or in places of unstable soil.

The supporting element may include a pipe on which the said blade is mounted, and inside which a rotation drive of the supporting element and a control for expanding or narrowing the reservoir are located.

The drive for expanding and narrowing the tank may be a compressor.

In a preferred embodiment, the reservoir is at least partially closed by a flexible bridge, the edges of which are fixed to the auger blades. For this fixing the jumpers on the blades of the speck, on each side of the latter, a groove can be made, passing at a constant distance from the base of the blade, and each edge can be made with the possibility of installation in the specified groove. The specified jumper and tank can be made of elastic air and waterproof material that is resistant to abrasion. The material of the tank has a small mass, so the mass of the supporting-running element is small but compared with the known supporting-running elements. When expanding, the reservoir occupies the entire inter-turn volume, turning the supporting-running element into a rolling drum, which ensures the movement of the supporting-moving element in the direction perpendicular to the axis of the supporting-moving element, and its speed, as well as maneuverability, increase significantly. When the tank expands, the jumper stretches simultaneously with it, and when the tank narrows, the jumper shrinks simultaneously with it, which ensures a quick transition of the support element from the screw mode to the rolling mode. When expanding, the tank also serves as a damper, absorbing dynamic loads on the supporting-traveling element when it collides with unevenness of the moving surface, and also to a lesser extent damages the road surface (no more than tires of automobile wheels). Depending on the degree of expansion, the tank may go beyond the volume of the inter-turn space, in this case, damage to the road surface when moving the proposed bearing element will not occur.

The tank can be divided by partitions into independent chambers, each of which has an opening connecting the chamber to the compressor.

The edge of the helical blade is preferably provided with a replaceable elastic element.

In addition, according to the present invention, there is provided a vehicle comprising at least one supporting element according to the invention, and comprising a frame having two parts that are articulated to each other. Each of the two parts of the vehicle frame may be provided with at least one supporting element. These parts of the frame are interconnected with the possibility of separation. The swivel joint increases the maneuverability of the vehicle.

Each part of the frame can be equipped with folding wheel supports, while the wheel supports can be individually equipped with a braking system. Thanks to the hinged wheel bearings, the vehicle can be moved in case one of the supporting-traveling elements fails. Each of the two parts of the frame can be equipped with one supporting-running element, including a screw, moreover, the blade of one supporting-running element is left-handed, and the blade of the other is right-handed, and a reservoir made with the possibility of expansion upon receipt of the working substance and constriction upon exit of the working substance.

Each of the two parts of the frame may contain a pair of supporting-running elements, including a screw having a helical blade, in the inter-turn space of which a tank is installed, made with the possibility of expansion upon receipt of the working substance and narrowing upon exit of the working substance; moreover, the screw blades of one pair of support-running elements are left-handed, and the screw blades of the other pair are right-handed, and each pair of supporting-travel elements rotates with the same angular velocity.

DETAILED DESCRIPTION OF THE INVENTION WITH REFERENCES TO THE DRAWINGS The supporting element 1 shown in FIG. 1 includes a screw that includes a pipe 2 and a screw blade 3 connected to the pipe 2. The pipe 2 may have ends 4 in the form of a truncated cone. In the inter-turn space of the blade 3, a reservoir 5 is installed, shown in FIG. 1 narrowed. The reservoir 5 is made of rubber with high elasticity and high tensile and abrasion resistance. Preferably, the reservoir 5 occupies the inter-turn space of the blade 3 along its entire length and width, but it can occupy at least some part of it. From Fig. 1 it can be seen that the reservoir 5 in a constricted state occupies a small volume of the inter-turn space of the blade 3, but its entire width is almost its entire length. Figure 2 shows the supporting element 1 with an expanded tank 5, which occupies the entire volume of the inter-turn space. From FIG. 1 and 2 it is seen that the tank 5 is spirally wound in the inter-turn space of the blade 3, and the ends b of the tank 5 are fixed on the cylindrical part of the pipe 2 by means of a plate 7 and screws (not shown in the drawing), so that the tank 5 is tensioned between those parts of the pipe 2 on which it is fixed. The ends 6 of the tank 5 can also be fixed at the ends 4 of the pipe 2. The fixing of the ends 6 of the tank 5 can be ensured by any suitable mechanical means. The tank 5 as a whole has a tubular shape, but may have some narrowing at its ends 6 for the convenience of its fastening on the pipe 2.

On both sides of the blade 3, grooves 8 of the same cross section are made, one on each side of the blade 3. The grooves 8 extend along the entire length of the screw blade 3 at a constant distance from the base 9 of the screw blade 3, which is located on the surface of the screw pipe 2. The distance at which the grooves 8 are removed from the base of the screw blade, and hence the surface of the pipe 2 of the screw, is constant. In Fig. 3a, this distance is indicated by a. For clarity, the proportions in the drawings are changed.

The supporting-traveling element is equipped with a jumper 10, which generally has the form of a tape, which can have tapers at the ends (not shown in the drawings) for convenience of its fastening on the pipe 2. The jumper 10 is made of rubber with high elasticity and high tensile and abrasion strength . The width of the bridge 10 is a certain amount greater than the width of the inter-turn space of the blade 3. This value corresponds to two depths of the groove 8. The edges of the bridge 10 have thickenings of the same cross section along its entire length. These thickenings have a cross-sectional shape corresponding to the cross-sectional shape of the groove 8. FIG. 36 shows how the thickenings of the bridge 10 are placed in the grooves 8, whereby the bridge is fixed in them and is parallel to the surface of the screw pipe 2. The jumper 10 is tightly tightened with an interference fit at the ends of the supporting element 1, so that it can hold the tank 5 when it is narrowed, in a compact form (Fig. Zb), to further protect the tank 5 when it is in the expanded state, and ensure the smooth running of the supporting-running element 1. The ends of the jumper 10 are mounted on the pipe 2 similarly to the ends b of the tank 5, namely by means of the plate 7 and screws (not shown in the drawing), while the jumper 5 is tensioned between those parts of the pipe 2 on which it is fixed. The fastening of the ends of the jumper 10 may be provided by any other suitable mechanical means. The jumper 10 can be reinforced with flexible strong threads oriented in the longitudinal and transverse directions.

When the reservoir is expanded, the jumper 10 is extended due to the expansion of the reservoir 5, comes into contact with it and repeats its contours in the area of contact. For clarity, in FIG. 2 and FIG. 1, the jumper is not shown, and the tank 5 is shown by a solid thick line, and the pipe 2, the ends 4 of the pipe, the blade 3 and the grooves 9 are shown by a dashed line.

The edges of the jumper 10 are installed in the grooves 9, which are shown by a solid line in the area of the drawing, where the surface of the tank 5 is cut off, and a dashed line in the area of the drawing, where the jumper and the tank completely cover the inter-blade space. In FIG. 36, the blade 3 is shown in section in an enlarged view, which shows how the jumper 10 is installed in the grooves 9, and the tank 5 is in a narrowed state.

In Fig. 3B, the blade 3 is shown in an enlarged section on which the tank 5 is shown in an expanded state and the bridge 10 The supporting-traveling element 1 can be filled with a replaceable elastic element 11 along its entire length (see Fig. Zb), which is placed on item 3. Element 11 is made of rubber, but may also consist of several layers of rubberized cord similar to that used in car tires. Replaceable elastic element 11 provides a smooth running of the support element and prevent unwanted damage to the movement surface.

Tank 5 may be continuous inside. However, an implementation option is advisable in which the tank 5 is divided into separate chambers 12 by partitions 13 (Fig. 4), since this increases the survivability of the tank 5, and, accordingly, of the supporting-traveling element 1. The partitions 13 are made of material similar to the material of the tank 5 and jumper 10 In FIG. 4 is a schematic longitudinal sectional view of the reservoir 5. Each chamber 12 is provided with an opening for the entry and exit of the working substance from it, and each the hole is equipped with a shut-off solenoid valve (not shown in the drawings).

Figure 5 shows the vehicle 14, containing two parts 15 and 16 of the frame, articulated to each other by means of a hinge 17, and two support elements 1, each installed in the corresponding part of the frame through axes 18 so that the longitudinal axes of the bearings elements 1 are parallel to each other.

Parts 15 and 16 of the frame are provided with a drive for rotating the screw pipe 2 and a drive for controlling the expansion or contraction of the tank 5 (not shown in the drawings). Each pipe 2 with the help of the axes 18 is installed in the corresponding part of the frame of the vehicle 14 and is driven into rotation by a drive (not shown in the drawings). The rotation drive of the screw pipe 2 is mounted on the frame. The rotation of the pipe 2 is due to the internal combustion engine of a sufficiently large power comparable to the engine power of a tracked vehicle. The drive control expansion and contraction is located inside the pipe 2 of the screw and is a compressor. The compressor can be driven from the same engine as the pipe rotation drive 2.

Fig. 6 shows a vehicle 14 comprising two frame parts 15 and 16, articulated to each other by means of a pivot joint 17, and two supporting-travel elements including a screw. Two supporting-traveling elements are installed each in a separate part of the vehicle frame 14 by means of axles 18. When fastening the supporting-moving elements of each in a separate frame, the longitudinal axes of the supporting-running elements are parallel to each other. One of the supporting elements is a supporting element 1 according to the invention, and the other supporting element 19 is a screw pipe with a continuous helical blade, the screw blade of one of the supporting elements is left-handed and the screw blade of the other supporting elements right-handed.

7 shows a vehicle 14, which contains two parts 15 and 16 of the frame articulated to each other by means of a swivel joint 17, each of the parts of the frame contains a pair of support elements 1 according to the present invention, the blades 3 of one pair of support elements 1 left-handed, and helical blades 3 of the other pair right-handed, and each pair rotates at the same angular velocity.

To move in difficult terrain conditions, the tank 5 is in a narrowed state as shown in Fig. L, that is, the vehicle, including the supporting-traveling element 1, moves like a regular auger. The screw pipe 2 rotates with its drive, the screw blade 3 penetrates the ground, and the vehicle moves in the direction along the longitudinal axes of the pipe 2.

In the case when two supporting-traveling elements, one of which has a left-side blade and the other right-side one, are each installed in a separate part of the frame, which are articulated to each other via a swivel joint 17, the vehicle trajectory in the auger mode is controlled without a swivel 17, by stopping and fixing one of the supporting-running elements, while the other supporting-running element 1, rotating, rotates the vehicle 14 (Figure 5).

Similarly, they control the vehicle’s trajectory in the auger mode, in the case when two supporting-traveling elements, one of which has a left-hand blade and the other is right-sided, and one of which is the proposed supporting-running element 1, and the other is a screw pipe with a continuous helical blade, each is installed in a separate part of the frame, which are articulated to each other by means of a swivel joint 17 (Fig.6); and in the case when two pairs of support-running elements 1, one pair of which has a left-side blade and the other right-hand, are each installed in a separate part of the frame, which are articulated to each other by means of a hinge 17 (Fig.7).

If necessary, change the movement of the vehicle 14 to the opposite (reverse) change the direction of rotation of the supporting-running elements 1 to the opposite. For a sharp change in the axial direction of movement of the vehicle 14 to a direction perpendicular to the longitudinal axes of the supporting elements 1, the working medium, for example, air is pumped through the compressor through the inlets available in each chamber 12 of the tank 5. When the tank 5 is completely filled with air, it fills the entire volume of the inter-turn space of the blade 3. The jumper 10 is stretched together with the tank 5, providing additional sealing of the tank 5, as well as cushioning when moving the supporting-traveling element. Thus, the supporting element moves in the rolling mode, which is the main mode of operation of the proposed vehicle

In the case when two supporting-traveling elements, one of which has a left-hand blade and the other right-hand, are each installed in a separate part of the frame, which are articulated to each other by means of a swivel joint 17, the vehicle trajectory in the rolling mode is controlled by turning the swivel joint . The swivel allows the vehicle to easily maneuver on the moving surface.

In addition, in this case, there is another option for controlling the vehicle’s trajectory in rolling mode, which is carried out by stopping and fixing one of the support elements 1, the release of the working substance from the other support elements 1, which continue to rotate, so provide turning of the vehicle. Similarly, they control the vehicle’s trajectory in rolling mode in the case when two supporting-running elements, one of which is the proposed supporting-running element 1, and the other is a screw pipe with a continuous helical blade, are each installed in a separate part of the frame, which articulated by hinge 17.

In the case when two pairs of supporting-traveling elements 1, one pair of which has a left-hand blade and the other right-hand, are each installed in a separate part of the frame, which are articulated to each other by means of a swivel joint 17, the control of the trajectory of movement is carried out by rotating the swivel joint, as in the first case indicated, driving a vehicle in rolling mode. In the event of a pressure drop in one chamber or some chambers, the leaky chamber is closed by a shut-off solenoid valve, if the pressure drops slowly, the compressor starts. In the event of failure of one of the support-running elements, it becomes necessary to disconnect one of the parts of the frame, so each part of the frame is equipped with folding wheel supports (not shown in the drawings) individually equipped with a braking system.
