Description

 The invention relates to the field of transport, mainly to vehicle propulsion, and can be used in cross-country vehicles - in all-terrain vehicles, snowmobiles and swamps, in agricultural vehicles, in construction and road vehicles, etc., as well as in amphibians. In addition, it can be used to quickly convert vehicles of normal cross-country ability (mainly containing active suspension) into vehicles of increased and even high cross-country ability, and in the presence of a displacement hull or floats, also amphibians.

 Known propulsion vehicle (US Pat. France N 713978, CL 1, gr. 10, published. 1931), containing a rim of an even number of articulated joints supporting sections with the same distance between the geometric axes of the hinges of each of them (hereinafter referred to as caterpillar contour), the hub and an even number of rectilinear motion connecting devices between them, arranged with a uniform angular pitch relative to the geometric axis of the hub in the plane of rotation of the propulsion device or in a plane parallel to it, and their facing rim ends pivotally connected with him in the ground, evenly spaced along its length. These connecting devices are pivotally connected with both the bypass and the hub, and therefore cannot bear a vertical load, although they transmit torque from the hub to the bypass, which ensures its movement. Therefore, inside the caterpillar contour coaxially to the hub, there is a toothed wheel attached to the connecting devices, which rolls along the lower branch of the contour, engaging with teeth. At the same time, it perceives a vertical load.

 The disadvantages of this mover: insufficient fifth wheel due to the relatively small size of the contact spot; poor rowing properties due to the low height of the rowing profile; excessive weight and metal consumption due to the presence of a support wheel and a large (20) number of connecting devices; design complexity due to the presence of teeth on the support wheel and hinges on the hub.

 The closest in technical essence and in the achieved result (prototype) is the propulsion device of the vehicle, which contains a caterpillar contour, a hub and an even number of connecting devices of rectilinear movement located in the plane of rotation of the propulsion device or in a plane parallel to it and with their ends facing the hub connected to it in places located with equal angular steps relative to its geometric axis, and the ends facing the rim pivotally connected to it in places evenly spaced along its length. The ends of the connecting devices facing the hub are pivotally connected to it and at the same time can move along the slots in it. Although this propulsion device is simpler in design than the previous one (for example, the gear wheel has been replaced with a disk with a smooth periphery), nevertheless, the remaining disadvantages mentioned above are preserved in it.

 The purpose of the invention is the development of a propulsion device with an increased support-and-grip terrain, with improved rowing properties, with reduced mass and material consumption, with a simple design.

 In order to achieve the objective of the invention, in a vehicle propulsion device comprising a tracked contour, a hub and an even number of rectilinear motion devices connecting therebetween located in a plane of rotation of the propulsion device or in a plane parallel to it, and with their ends facing the hub connected to it in places located with equal in angular steps relative to its geometrical axis, and with the ends facing the contour pivotally connected to it in places evenly spaced along its length, four or six sole devices of the specified type. These devices are located radially and the ends facing the hub are rigidly connected to it or structurally combined with it. Due to this attachment or association, the hub assembly - connecting devices becomes self-supporting, which allows you to abandon the disk and reduce the radial size of the hub. The disk now does not prevent compression of the contour in the vertical direction. Lowering under the action of the load, the hub causes the lowering of the connecting devices, and therefore the contour is compressed in height. As a result, a significant part of the lower half of the contour approaches the soil, due to which the ratio of the contact length to the perimeter of the contour increases and thereby the locomotive traction is increased. In this case, the mover operates in caterpillar mode.

 In contrast to the usual caterpillar contour, the configuration of which remains unchanged theoretically during movement, in this mover the configuration of the caterpillar contour changes periodically. For example, with four connecting devices, configurations are possible for a vertical rhombus, an inclined rhombus, a square, etc. For six connecting devices, a regular triangle with a bottom-down base, a regular hexagon with a bottom-down base, etc. can be configured. With any track configuration, the geometric center of the propulsion hub is equidistant from the sides of the corresponding geometric figure.

 The ratio of the contact length to the track circumference can be 0.25-0.5 in the case of four connecting devices and 0.17-0.33 in the case of six connecting devices. This is more than 0.15 of the prototype.

 The above expression "... with their ends facing the hub, these (connecting) devices are rigidly attached to it (the hub) or are structurally combined with it..." means that the node of such attachment (association) is made in such a way that the translational, for example vertical, movement of the hub under the action of the load applied to it leads to the forced lowering of the hinges of the contour and a change in its configuration.

 When the contour is compressed, the height of its rowing profile increases, which leads to an improvement in its rowing properties. In this case, the mover operates in rowing mode.

 The mover becomes self-supporting and the drive is no longer needed. In addition, the number of connecting devices and sections of the caterpillar rim is reduced (from 20 to 4 or 6).

 A rigid connection by design is always easier than a movable, including articulated.

 These differences ensure the achievement of the claimed positive effect. These differences are also significant.

 The essence of the differences is also confirmed by the fact that from the distinguishing features “the number of connecting devices between the caterpillar rim and the hub is four or six” and “the connecting devices are arranged radially and their ends facing the hub are rigidly attached to it or structurally combined with it” does not logically aggregate property: increase in the ratio of the length of the contact spot to the perimeter of the caterpillar contour. This property appears only as a result of the interaction of the signs of the restrictive and distinctive parts of the claims.

 The mover can work in caterpillar and rowing modes and therefore ensures the movement of the vehicle both on land and on water. Traffic is provided both on roads and without roads (for example, on soft soils and rough terrain), as well as overcoming water barriers (both afloat and ford, including approach to them, forcing and getting out of them).

 The proposed mover can be used in a variety of vehicles, from a car to an ordinary cart. For brevity, the term "vehicle" is used instead of the term "vehicle".

In the first example of a practical embodiment of the invention (Fig. 1), the propulsion device comprises a hub 1, a caterpillar contour consisting of four sections 2, 3, 4 and 5 and four connecting devices between the hub and the contour of the rectilinear movement (for example, telescopic) 6, 7, 8 and 9 (hereinafter referred to as telescopes). These telescopes are radially arranged with a uniform angular pitch (about 90 ^° ) relative to the geometrical axis (not shown) of the hub 1 in the plane of rotation of the propulsion (or parallel to it) and are rigidly connected to the hub with their ends facing it (or structurally combined with it). With their ends facing the caterpillar contour, the telescopes are pivotally connected to it at places 10, 11, 12 and 13, evenly spaced along its length. The telescope contains a knee: the root 14, intermediate 15 and 16, as well as the final 17. The root knee 14 of the telescope is rigidly connected to the hub 1 inseparably (for example, welded) or detachably (for example, mounted on hairpins), or structurally combined with it (cast, molded and etc.).

 Each knee of the telescope (Fig. 2) is made in the form of a pipe with a flange at the end remote from the hub 1. In the flanging zone there are wiper and o-rings with stuffing box nut, as well as rolling elements 18, for example two, in the plane of the mover and two in the plane perpendicular to it. Rolling bodies are used to reduce friction, which is necessary to prevent distortions, seizing, etc. in contact between adjacent surfaces of the knees. On the ends facing the hub in the knee are other rolling bodies 19 of a similar purpose. Rolling bodies are located in recesses in the walls of the knees. Between the flanges of the knees, compression springs or tension springs equipped with reversers can be located, and inside the springs, compression buffers (not shown), for example rubber ones. At least one of the buffers can be made in the form of a rubber hollow body operating on a slice (which is necessary for the perception of high-frequency vibrations).

 The spring, covering the final elbow 17 of the telescope, at one end abuts the flanging on the intermediate elbow 16 of the telescope, the other rests on the cup at a portion of this elbow remote from the hub. This section is equipped with a thread on which a nut and a lock nut are mounted to regulate the position of the cup and the degree of preliminary preloading of the spring during operation of the mover. The length of the cut section is selected with a margin sufficient to fully unclench the spring, for example, for the period of storage of the mover in the warehouse. This section is connected with a fork 20, which is pivotally connected to adjacent sections 2 and 5 of the caterpillar contour. Outside the telescope is covered by a removable or opening protective cover 21 of variable length, for example a bellows. Instead of a bellows 21, a telescopic lightweight tube may be used. In either case, a detachable connection (e.g. a bayonet mount) may be provided to facilitate access to telescopes. To prevent accidental (when the bellows is open) contamination of the telescope knees, their surface can be coated with a water-repellent composition, for example, based on polyethylene or polyolefin.

 In FIG. Figure 2 shows a telescope consisting of four tribes, but there can be more or less of them, which depends on the required maximum compression ratio of the track contour (the ratio of the lengths of the diagonals of a rhombus in the most compressed state when the mover is operating). The magnitude of this degree depends on factors such as permissible clearance, hub diameter, etc. With a sufficiently large thickness of the walls of the hub, the root knee can function as a radial channel in it, and then the telescope can have only one movable knee. Instead of pipes, box-shaped profiles, for example, square, rectangular or triangular cross-section, including with cut corners for convenient location of rolling elements in the form of cylindrical rollers in them, can be used. Other profiles can be used, for example, a hollow I-beam having maximum rigidity with minimum weight. Instead of a multi-telescope, a single telescopic spring, for example a conical one, from a sheet blank can be used.

 In order for the end section of this spring not to bend, deviating from its rectilinear geometric axis, a hard short one can be inserted inside (corresponding to the length of this section (core), for example, conical with a smooth or screw surface). When the spring is stretched, this core supports the indicated section, and when compressed, it limits the limits of its compression, abutting against the hub wall. This core may be hollow and provided with internal stiffeners and lightweight cutouts. The core end facing the hub is free, and the other is connected to the plug 20.

 A multi-telescope is possible, in which only some knees, for example the root, are made in the form of telescopic springs. In any case, the terminal knee can be solid or hollow, but with reinforcing diagonal struts. A telescope is possible in the form of several flat knees interconnected like elements of a slide rule (body - one knee, engine - another, etc.). A prefabricated telescope is possible, consisting of elbows of various profiles and / or) types. A telescope is possible with hollow wheels screwed into each other with a non-self-locking screw thread. Instead of a telescope, devices of rectilinear motion of any other design can be used, for example, in the form of a flat articulated poly-linker or in the form of a translational pair (translational mechanism of several such pairs), so long as they ensure the straight movement of the fork 20 in the direction from the hub on the working section of their path 1 or to her.

 A connecting device taken from the prototype (tubular spoke) may also be used.

 The root knee of the telescope can be equipped with external stiffeners, and the final one with internal diagonal struts. The strength and rigidity of the intermediate elbows are provided by a rational choice of cross-sectional configuration, dimensions, material, hardening treatment, etc.

 The telescope can be equipped with a device, such as a key, to prevent axial rotation of the knees. Lightening cuts can be made in the walls of the knees.

 Balls can be used as rolling bodies, or even better, corset or barrel-shaped rollers with a radius of curvature equal to the radius of curvature of the inner surface of the mating knee. In the case of flat knee walls, cylindrical rollers can be used.

 In the outer surface of the knees, longitudinal grooves of the desired profile can be extruded, in which rolling bodies are conveniently located and / or moved. These bodies can be made of an elastic material, for example, fluoroplastic.

 Instead of individual rolling bodies, group ones can be used, for example, in the form of many balls or rollers embedded in many nests in one of the mating surfaces, as well as in the form of machine-type ball loops that are especially conveniently located in the relatively thick root knee of the telescope or in a special this knee rush (local thickening).

 Instead of rolling bodies, antifriction gaskets made of carboplasts or self-lubricating from porous bronze with a thin layer of fluoroplastic with lead filler deposited on it can be used. In the manufacture of at least some non-ferrous metal elbows, simplified anti-friction measures can be dispensed with. But a particularly great simplification at the same time as reducing the mass of the telescope is achieved by using anti-friction durable structural plastics, for example reinforced. You can do without anti-friction linings, using a treatment that simultaneously increases both slipperiness and hardness (against scuffing, seizing, etc.), for example sulfocyanation, or applying grease.

 To increase the cyclic strength in the propulsor, tubes and rolling elements can be used subjected to hardening technological processing (polishing or rolling) along the surface of mutual contact. Cyclic strength is also enhanced by the use of said springs and / or compression buffers to mitigate shock loads.

 The springs can be and are located not only on telescopes, but also between adjacent sections of the bypass and / or between telescopes and adjacent sections of the bypass. Instead of compression springs, tension springs can be installed. Instead of tension springs (compression) or together with them, twisting springs can be used on the hinges of the bypass or inside them. If the telescope is reliably sealed, then pneumatic ones can be used instead of mechanical springs: compressed gas or air pumped into the internal cavity of the telescope. By adjusting its pressure, you can adjust the stiffness of the springs.

 Instead of coil springs, plate-shaped ones can be used to reduce dimensions. Coil springs may have varying stiffness, shaped springs may also be used.

 Any two telescope elbows that enter into each other can be connected by a torocylinder (an elastic cylindrical tube that turns out during mutual translational movement of the elbows). With sufficient sealing, such a torocylinder made of an antifriction material, for example fluoroplastic, not only prevents or substantially reduces friction between the telescope’s knees, but also provides the telescope with elastic properties (due to the air compressed in the telescope’s knee cavities when it is compressed), so you can refuse from the springs.

 Sometimes the spring and / or buffers can be discarded for any telescope design if the propulsion device is used only for a short time and / or works on soft ground, for example, on marshy, including in the tundra, peatlands, etc.

 The hub can be made not only in the form of a cylindrical sleeve, but also in the form of a flat disk, and then the root knees of the telescopes are attached to it not with their ends, but with their sides.

 Located on the final elbow 17 of the telescope 6, the fork 20 with its eyes is located coaxially with the eyes of the hinge on adjacent sections 2 and 5 of the caterpillar contour and connected to them by means of a finger 2 with a stopper (not shown). In this case, a hinge assembly is formed, which, depending on specific conditions, can be equipped with a lubricating device or anti-friction elements and / or sealed or self-cleaning (a. From. USSR N 1066874, class B 62 D 55/20, 1981). But if the mover is designed to work on low abrasive soil, such as black soil, then the hinge can be open. Elastic elements, for example rubber gaskets, can be inserted into the hinge assembly.

 Although the number of eyes is minimal in this design, the assembly can be multi-eye. In any case, the surface of the hinge unit when driving on the road can be blocked by a removable cover (not shown) to protect the road surface from mechanical damage. If, on the contrary, it is necessary to strengthen adhesion to the supporting surface, for example, when moving on ice, then a pointed tip (not shown) is put on the hinge unit in the form of one or several spurs or a serrated plate, etc.

 Each section of the caterpillar rim is made in the form of a frame covered by a supporting surface, for example, a metal flat supporting sheet to which lugs, spurs, etc. are attached or stamped in it, which can be of any desired configuration, permanent or interchangeable depending on type of soil and made of metal or other material, for example elastic, allowing movement on the road without destroying its coating. Lugs, spurs, etc. are located on the supporting surface of the sheet, and sometimes also on the supporting surface of the frame. The ends of the frame can be equipped with through holes (channels) for extruding dirt (self-cleaning).

 The frame can be not only a rectangular frame in terms of a frame, but also another suitable shape, for example, an H-shaped one. In the latter case, the crossbar of the frame is in the plane of rotation of the mover or in a parallel plane. The crossbar can be straight, concave, convex or have any other shape.

 The frame, when viewed from the side, may not be straight, but have some other configuration, for example, convex, including curved along the rolling radius, concave or wavy.

 Possible execution (Fig. 5), in which the support sheet is concave to improve soil compaction and thereby to further increase the permeability. In this case, the frame can also be concave.

 In FIG. Figures 4 and 5 show frames with the bell facing down, but frames facing the bell up are also possible. In this case, the eyes will not be located at the lower edge of the end of the frame, but at its upper edge. A frame is possible not with flat edges, but with edges in the form of a dihedral angle and with the arrangement of eyes on the edges of these corners. It is also possible to have a frame with eyes significantly raised above the ground to reduce their clogging with dust, dirt, etc.

 In FIG. Figures 4 and 5 show frames with a constant distance between the geometric axes of the hinges, but this distance can be adjusted by making the frame in the form of two parts connected by the principle of a slide. The adjusted distances during the operation of the propulsion device must remain constant.

 The support sheet can be only simple (Fig. 4) or concave (Fig. 5), but also convex or curved along the rolling radius of the propulsion device to improve ride smoothness when driving on the road. It may also have some other configuration, e.g. , wavy in the form of a washboard. The support sheet can also be made in the form of a section of a concave spherical surface or a concave surface of a part of a polyhedron, for example, have a roof-shaped configuration. The support sheet can be made not only of metal, but also of plastics, including reinforced, as well as from metal sandwich type.

 Depending on the properties of the soil, the backing sheet can be not only continuous, but also openwork or trellised. When moving on the ground, holes in the sheet contribute to the extrusion of dirt, i.e. self cleaning. When moving afloat, the perforated sheet, if necessary, is blocked by an overhead light sheet, for example fiberglass, or the holes are blocked by plugs.

 The support sheet may not be rigid, but elastic, as well as freely deformable with copying of the soil profile. It can be made of an elastic material, for example, of sheet steel or sheet rubber, or is composed of a plurality of adjacent rubber rope or coil springs. It can be equipped with several small tracked tracks. It can also be made of rigid material, but attached to the frame by means of elastic elements. The backing sheet can be not only permanent, but also adjacent or removable.

 A variant is possible in which the frame is completely absent, and sections 2 - 5 of the caterpillar contour are made flexible or made of flexible material and pivotally connected to telescopes in places 10 - 13.

 For any performance of the tracked section, it can be worn on a paved shoe made of solid or perforated rubber or in the form of a pneumatic with a configuration similar to the known configuration of the tracked chain pneumatic drive when driving on a paved road. With frequent gathering on asphalt, the section can be made in the form of non-replaceable pneumatic blower under any operating mode.

 The surface of the shoe facing the support sheet (frame) can be smooth or provided with recesses for the entry of spurs (lugs) into them. In the first case, before placing the shoe on the mover, the spurs (lugs) are removed from the surface of the sheet (frame), for example, they are unscrewed, and in the second they remain in place.

 The removable shoe can be secured to the track contour section by means of bolts (studs) and nuts, or by means of a quick coupling, for example, articulated lever grip (AS USSR N 1152859, class B 62 D 55/28, 1982).

 The non-replaceable shoe can be made in the form of an elastic, for example rubber, structure fixed to an intermediate support, which is fixed to the frame of the contour section, or in the form of a rubber structure welded directly to the frame.

 A visor (for example, in the form of a comb) can be installed on both or on one of two adjacent sections of the contour in the region of its end to protect the hinge assembly from mechanical damage by its soil, stones, etc. The visor hangs over this node and not only protects it, but also improves the adhesion of the propulsion device with soil or ice, working as an additional lug (pore).

 On the plug 20 or on the end of one of the sections of the track contour attached to it, a permanent, removable or retractable, for example extendable, tip with a part buried in the ground can be fixed, the configuration of which ensures the formation of holes of the required shape with a conical, wedge-shaped, etc. Such holes serve for planting seedlings in them or for the accumulation of moisture. A tip of a different configuration can be fixed, for example, increasing the adhesion of the mover to ice. The geometric axis of the tip can be offset relative to the geometric axis of the connecting device.

 To improve the adhesion of the mover to the ground, teeth, protrusions, etc., can be made or fixed at the ends of the eyes. To reduce soil chipping and reduce turning resistance, the side edges of the frame and shoe can be beveled or rounded. The ends of the rubber part of the shoes can be reinforced with durable material, for example, equipped with a metal plate.

 On the hub and on the surfaces of the sections of the caterpillar contour facing it, sharp-toothed combs (such as saws), knives, etc. can be installed. for cutting stems of aquatic plants when moving afloat. When inoperative, these combs and knives are protected by removable covers.

 To increase durability, all parts of the caterpillar contour are made of wear-resistant materials and subjected to rational hardening treatment. Any part of the mover can be made of metal or structural plastic, including reinforced. In acceptable places lightening cutouts or holes can be made.

 The distances between the outer surface of the hub (in any place) and the surface of the caterpillar contour facing it, as well as the course of the telescopes, should provide the possibility of unhindered compression of the contour to the required value. However, there may be places on the hub and / or on the contour, for example, protrusions specifically designed to interact with the inner surface of the contour (or with the outer surface of the hub) when the contour reaches the maximum compression ratio. Such places play the role of stops and do not allow excessive compression of the contour, thereby facilitating the operation of the springs.

 Due to the rigid connection (or constructive union) of the telescope root knees with the hub, a truss was formed in the middle of the mover, giving it self-supporting properties. This allowed to abandon heavy disks. In addition, the number of connecting devices has decreased. Due to the long (elongated in the direction of travel) contact spot, it was possible to reduce the width of the caterpillar contour. All this led to a decrease in material consumption and mass of the mover in comparison with the prototype.

 For simplicity, the telescopes are depicted in ordinary straight lines, without highlighting the knees. When the mover is operating, its parts during the rotation of the hub are continuously mutually moving, and he himself takes a lot of cyclically changing configurations, among which several typical ones can be distinguished.

Suppose that at some point in time (Fig. 6), the mover when moving on a flat solid surface has the configuration “vertical rhombus” (shown by a solid thick line) and a load P is applied to its hub 1. Since each telescope is unidirectional and its root knee 14 (Fig. 1) is rigidly connected to the hub or structurally combined with it, then forces Q ₁ and Q ₂ are applied to the lateral vertices 11 and 13 of the rhombus and the condition Q ₁ = Q ₂ = P / 2 is met. Under the influence of these two forces, the lower sides 2 and 5 of the rhombus deviate downward, turning (relative to the fulcrum 10 on the ground) in the direction of the arc arrows 23 and 24, and the vertices 11 and 13 are described by arcs with a radius equal to the length of sections 2 and 5. This leads forced lowering and lengthening of the horizontal telescopes 7 and 9. Their lowering leads to a shortening of the lower telescope 6 and to the compression of its springs. Their lengthening leads to the forced release of their springs, lowering the peaks 12, shortening the upper telescope 8 and compressing its springs. As a result, the rhombus collapses vertically, acquiring the configuration of a square with a vertical diagonal (shown by a dashed line). With further lowering of the hub, this process continues, the mover becomes more flattened and at the end acquires the configuration of a horizontal rhombus (shown by a solid thin line). The rhombus is flattened until this process is suspended by springs compressed to the limit. The maximum allowable compression ratio is regulated by nuts on the telescope end bends, rubber buffers or other restraints, including interchangeable ones, for example mounted on the ends of adjacent sections of the caterpillar contour facing each other.

 If the maximum allowable compression ratio is incorrectly adjusted or if one or another limiter fails, excessive compression of the spring can occur with subsequent loss of elasticity. To prevent this phenomenon, protrusions are placed on the coil of the springs, welded or decorated in the manufacture of rods, from which springs are wound, directed parallel to the geometric axis and the springs. With extreme compression of the springs, these protrusions prevent the excessive convergence of the coils. The height of the protrusions corresponds to the minimum allowable clearance between the turns of the most compressed spring.

 The terms “rectilinear motion device” and “rigidly attached” are used not in an idealized, but in a purely technical sense. It is understood that the features of the invention in conjunction provide for the forced movement of the side hinges (Fig. 6) to the sides and down, and the upper hinge down when a vertical load is applied to the hub. In a real mover, the hub, connecting devices and hinges can be located not on a common geometric line, but on a certain line (for example, a broken line) with a certain deflection arrow. The permissible deflection can only be set functionally, as described above. Therefore, if in a real mover the geometric centers of the hub, connecting devices and hinges are not located on one straight line, i.e. if the connecting devices provide approximately rectilinear movement, the hub is connected to them almost rigidly, etc., then such a mover also falls within the claims of this application.

Suppose that, rotating clockwise, the mover at some point in time is in the "inclined rhombus" configuration (Fig. 7), in which its large diagonal 12, 10 is located not vertically, but inclined at a certain angle α to the road. At the same time, the load R is still applied to the hub. The force P can be decomposed into two components P ₁ and P ₂ (Fig. 8), directed along the large and small diagonals of the rhombus. As a result of interaction with telescopes, friction forces P _t1 and P _t2 , conventionally shown on an enlarged scale, are also applied to the hub. Therefore, the difference of forces P ₁ - P _{t2 is} applied along the large diagonal, and the difference of forces P ₂ - P _t1 along the small diagonal. Moreover, P ₂ - P _t1 > P ₁ - P _t2 . The force difference P ₁ - P _t2 acts similarly to the applied vertical force P (Fig. 6), causing the rhombus to compress in the direction of the large diagonal, as a result of which it is flattened, and its lower base 2 approaches the ground. Springs on the long diagonal of the rhombus prevent its compression, and springs on its short diagonal help.

At the same time, the difference of the other two forces P ₂ - P _t1 creates a certain torque that rotates the rhombus relative to the top 10 counterclockwise, and thus also brings the base 2 of the rhombus closer to the ground. Thus, the base of the rhombus approaches the soil immediately for two reasons: due to the compression of the rhombus and due to its rotation.

When the base of the rhombus comes into contact with the soil, a support reaction occurs that compresses the rhombus along the small diagonal as well. Since P ₂ - P _t1 >> P ₁ - P _t2 , the compression along the small diagonal is stronger than the compression along the large diagonal and the base of the rhombus is firmly pressed to the ground (Figs. 9 and 10). The mover acquires a stable horizontal-base rhombus configuration. The upper acute angle of the rhombus (at apex 12) is turned to the left.

With further rotation of the hub clockwise, the rhombus under the action of a larger difference in forces P ₂ - P _t1 at first remains compressed more on the small diagonal than on the large. But as the hub turns, the steepness of the small diagonal decreases, and the steepness of the large increases. Therefore, there is a redistribution of forces, and the moment comes when P ₂ - P _t1 = P ₁ - P _t2 . In this case, the mover acquires the configuration "square with a horizontal base" (Fig. 11 and 12).

 With further rotation of the hub in the same direction, a further redistribution of forces occurs, as a result of which the mover again acquires the "rhombus with horizontal base" configuration, but with an acute-angled vertex facing right (Figs. 13 and 14).

 As a result, it turns out that in the motion phases shown in FIG. 7 - 13, section 3 of the caterpillar contour practically does not open from the ground, since the mover operates in caterpillar mode.

 The process of changing the configuration of the propulsion device depends on the amount of friction. If the friction is relatively small, then the base of the rhombus does not come off the ground. To reduce friction, appropriate antifriction measures are provided: the use of rolling bodies, sliding pads, etc. in telescopes.

 If the friction is relatively large, then the base of the rhombus is first somewhat detached from the ground (however, maintaining contact with it at the top of the rhombus), but then again falls on it.

 It follows from the foregoing that the configuration of FIG. 6 with a sufficiently small friction in the propulsion device is practically not achieved and was considered only to illustrate the principle of operation of the propulsion device. Instead, the construction of FIG. 7, and even more often in FIG. nine.

 Assume now that the hub of the propulsion device, which is in the stable configuration "rhombus with a horizontal base" (Fig. 13), continues to rotate clockwise. In this case (Fig. 15), the peaks 11, 12 and 13 move in a clockwise direction. Separate stages of movement (for example, for the vertex 11) are shown by the arc arrows 23 and 24. The mover is blocked at the top 10 of the obtuse angle, maintaining the “rhombus” configuration, but changing the support from the base 2 to the base 5 of the rhombus. In this case, the mover operates in a non-circular wheel mode. Then he begins to rise again, leaning on top 13 of an acute angle. The process described previously with respect to FIG. nine.

 As when passing through the “square with horizontal base” configuration (Fig. 11), and when rolling (Fig. 15), the direction of the rhombus vertex that is far from the ground changes to the opposite: if it was first turned to the left, it turns to the right, and vice versa.

 Thus, the propulsion cycle is accompanied by a periodic change in its configuration. The mode of its operation periodically changes: from tracked (Fig. 7-13) to non-circular (Fig. 15), then again to tracked, etc.

 The main phases of the resultant propulsion cycle during clockwise rotation of the hub are shown in FIG. 16. One of the sides of the rhombus is conditionally highlighted to make it easier to follow the process of movement.

 The following simplifications are introduced in this figure.

 Between the configurations “rhombus with a horizontal base" and "square with a horizontal base" the configuration "inclined rhombus" is omitted, because it is short-term, transitional and unstable.

 To save the area of the drawing, only the first half of the duty cycle is shown. Although the original support base has returned to its original support position, the upper sharp top of the rhombus is facing not to the right, but to the left. The second half of the working cycle, after processing of which all the elements return to their original position, is a mirror image of its first half.

 As can be seen from FIG. 9, 11, 13 and 15, a change in the configuration of the propulsor when the hub rotates clockwise is accompanied by a movement from left to right. In FIG. 9, the hub is located above the left end of the support section 2, in FIG. 11 - above its middle, and in FIG. 13 - above its right end. From FIG. 15 it is also seen that the hub moves from left to right (its three successive positions are clearly distinguished).

 When driving on the road (Fig. 17), the mover operates in the above order. To prevent damage to the road surface, as well as the road surface, asphalt-walking shoes are put on the track section, and asphalt-traveling covers are put on the hinges.

 When driving on rough terrain (Fig. 18), the mover works basically the same as when driving on a flat surface. When hit on a pothole or on a ledge, the bypass of the propulsion device, due to the dynamism of its design, is self-installing, which makes it easier for him to overcome them.

 When moving on soft ground (swamp, peat, arable land, approaching and moving away from the water barrier), the mover adopts configurations with it similar to those that it takes when moving on hard ground, for example, “horizontal rhombus”, “square with horizontal base "or" rhombus with a horizontal base ". Due to the small resistance from the ground, the mover can take the configuration of a "vertical rhombus" and "square with a vertical diagonal."

 The configurations “horizontal rhombus” and “square with a vertical diagonal” with a sufficiently large supporting area of the sections provide a sufficient reaction of the soil and prevent excessive penetration of the mover into the soil. The configurations “square with horizontal base” and “rhombus with horizontal base” under this condition also provide a sufficient response of the soil and prevent burial into the soil. The greatest concern regarding deepening is the “vertical rhombus” configuration. It all depends on the combination of the bearing capacity of the soil, the supporting area of the sections, their length, characteristics of the lugs (height, configuration, location, etc.), including spurs.

 With an unfavorable combination of these factors, the mover is buried in the ground until the lower peak of the rhombus abuts against a sufficiently strong layer (which, depending on the type of soil, can be at different depths). With an emphasis, the "vertical rhombus" is compressed and transformed into the "horizontal rhombus" configuration, which is accompanied by an increase in the reaction of the soil. If the lower apex of the rhombus does not reach a strong layer, then after 1/4 of the hub revolution, the mover, interacting with the ground, acquires the next configuration, for example, a “rhombus with support on the lower side”. In this case, the supporting surface of the contour increases significantly, due to which the depth of the mover decreases or stops and it "gets up." In a real car, several propulsors are used. It is unlikely that they would all be in a vertical rhomb configuration at the same time. Therefore, the car as a whole in any case has sufficient cross-country ability.

 In the initial “square with vertical diagonal” configuration, the mover works, as in the previous case, but in more favorable conditions, since the right angle is greater than the acute angle, and therefore the initial depth is less. The foregoing applies to soil with a very low bearing capacity. The mover works successfully on it. With a higher bearing capacity of the soil, the mover is even more successful.

 When driving on snow in winter (and on the tundra - and in summer), the mover ensures the movement of the machine due to the compaction of snow by sections of the caterpillar contour and / or adhesion of spurs to snow or to the soil of the tundra. In this case, the machine has a view similar to that shown in FIG. 17 and 18. The movement continues even if the machine rests on the snow or ground of the tundra (Fig. 19).

 The transfer of the mover from one operating mode to another, for example, from the road to the terrain and back, from marshy soil to snow and back, etc., occurs without any readjustment in it. In any of the above ground modes of movement, the machine is controlled in any known manner (for example, by slowing down the propulsion of one side). Shocks during movement are absorbed by the springs and buffers of the propulsion device, as well as the suspension of the machine.

 When driving in snow, ice or a swamp (tundra), when the car lies on its bottom, and also when moving afloat, it is necessary that the propulsion hub is located slightly above the bottom level. This requires lifting it, for example, by means of a suspension. Suspension can be used on the longitudinal, swivel in the vertical plane, levers (balancers) associated with a controlled power drive (hydraulic or pneumatic cylinder). Such a suspension is especially suitable if the machine is equipped with an automatic control or stabilization system for the body level. The balancers are made hollow and inside them there is a transmission (for example, chain) to the propulsors. In the case of a hydro- or electric drive of the mover, the motor may be located in its hub.

 When moving afloat (Fig. 20), the mover operates as a two-bladed paddle wheel and can take the configuration “horizontal rhombus”, “vertical rhombus”, “square with a vertical diagonal”, “square with a horizontal base” and “rhombus with a horizontal base”. As can be seen from FIG. 21-26, when the propulsion device rotates (for example, counterclockwise) with an angular velocity ω, any of these configurations, when interacting with the water flow in the sections of the bypass sections immersed in it, a left-handed reactive force H appears at any moment normal to the section plane. Its horizontal projection T is also directed to the left and is a stubborn force that provides translational movement to the left of the section (vector V), the hub, and with it the whole propeller, and hence the machine. For any of these configurations, the thrust force T is directed in the same direction (to the left). The efficiency of the propeller as a paddle wheel increases significantly in the case of a concave configuration section (Fig. 5) or with a flexible backing sheet. Alfer'ev M.Ya. Ship propulsion. M .: Water transport, 1938, p. 105 and 430.

 When moving afloat, the car is controlled in the same ways as when moving on land (for example, braking the propulsion of one side), but in combination with them or instead they can be used boat steering wheel.

 When overcoming water barriers, shoals, rifts, etc. are often found (especially in river deltas). The mover overcomes them on the go, without interrupting the movement.

 Although in FIG. 17, 18, 19 and 20 propulsors are shown in different configurations, they can be in the same configurations.

 This mover does not cause harmful soil compaction during agricultural work and therefore is environmentally friendly.

In the second example of a practical embodiment of the invention, the proposed propulsion device is equipped not with four, but with six telescopes to improve ride smoothness. By design, it is similar to a mover with four telescopes. The mover (Fig. 27) contains a hub 25, a caterpillar contour (not indicated) consisting of six sections 26, 27, 28, 29, 30 and 31 and six connecting devices of rectilinear movement, for example telescopic (hereinafter referred to as telescopes) 32, 33 , 34, 35, 36, and 37. These telescopes are located with a uniform angular pitch (about 60 ^° ) relative to the geometrical axis (not shown) of the hub 25 and in the plane of rotation of the mover (or parallel to it) and are rigidly connected to the hub) (or structurally with united) with their ends facing her, and with their tracks at the rim ends telescopes are articulated with them in places 28, 39, 40, 41, 42 and 43, evenly spaced along its length. The design of the telescopes and other parts of the propulsion device is similar to their design in the propulsion system with four telescopes.

 The operation of a six-telescopic propulsion device is basically similar to that of a four-telescopic propulsion. In the drawings, for simplicity, the telescopes are conventionally shown in straight lines, without highlighting the knees. When the mover is operating, its parts can take many configurations, which are reduced to several typical ones.

Suppose (Fig. 28) that when moving on a flat solid surface, the mover at some point in time has the configuration “vertically positioned regular triangle resting on top” 40 (indicated by a solid thick line) and that a vertical load P is applied to its hub. As a result, the forces Q ₁ , Q ₂ , Q ₃ and Q ₄ will be applied to its joints 38, 39, 41 and 42. Moreover, Q ₁ = Q ₂ = Q ₃ = Q ₄ = -P / 4. Under the influence of these forces, the mover will first go into the unstable configuration “regular hexagon resting on the top” (shown by the dashed line), and then into the stable configuration “regular triangle resting on the base” (shown by a solid thin line) with the corresponding lowering of the hub. During the rotation of the hub, the mover alternately changes from the stable configuration “regular triangle with support on the base” to the stable configuration “regular hexagon with support on the base”.

 Unlike a four-telescopic propulsion, the six-telescopic propulsion does not have a rolling phase (similar to Fig. 15) and it operates in a purely caterpillar mode.

When operating a six-telescopic propulsion device, it is possible to jam if two adjacent sections are not located on one straight line in the “right triangle” configuration, but “slip” through this position, as a result of which the propulsion acquires the “three-beam star” configuration. In order to prevent this from happening, limiters are provided that prevent the passage through an imaginary straight line connecting every three sequentially located hinges of the caterpillar contour. Even better, if these stops do not allow the sections to open at an angle that exceeds a certain maximum allowable value less than 180 ^° , for example 175 ^° . Such stops can be made in the form of protrusions or adjustable stops on facing each other ends of adjacent sections of the contour.

 The main phases of the propulsion duty cycle are shown schematically in FIG. 29. One of the sections of the contour is conventionally allocated to make it easier to monitor the process of movement.

 When driving on rough terrain, the mover works the same way as when driving on a flat surface. When hit on a pothole or on a ledge, the mover, due to the dynamism of its design, self-installs, which makes it easier to overcome bumps.

 When driving on the road, the mover works in a similar way. To prevent damage to the road surface, as well as the road surface, asphalt-walking shoes are put on the track section, and asphalt-traveling covers are put on the hinges.

 When moving on soft ground (including swampy ground, when approaching and exiting a water barrier, and also on plowing), the mover adopts the same previously indicated stable configurations with respect to the ground that it takes when moving on hard ground, and also unstable "right triangle with a vertex down" and "regular hexagon with a vertex down." With stable configurations, the area of the supporting surface of the mover is sufficient to prevent its penetration into the ground. With unstable configurations, the mover with its lower peak either reaches a relatively deep solid soil layer or does not reach it. In the first case, upon abutment in the solid layer, the mover changes its configuration to a stable one, after which the deepening stops. In the second case, its lateral sections come into action, cordoned off by their lugs with soil and create an additional reaction of the soil. If this for some reason does not occur or the additional reaction of the soil is insufficient, then after 1/6 of the turn of the hub the mover switches to the next stable configuration, creating sufficient supporting force and crawling out of the soil.

 When driving on snow in winter (and on the tundra - and in summer), the mover ensures the movement of the machine due to compaction of snow by sections of tracked contour or coupling spurs with snow or with tundra soil. As in the case of a four-telescopic propulsion, the movement continues even when the car rests on the snow or ground of the tundra.

 In any of the land modes of movement, the machine is controlled in any known manner, for example, by braking the propellers of one side. Shocks during collisions with unevenness and non-circularity of the mover are mitigated by its springs and buffers, as well as the suspension of the machine.

 Afloat, the propulsion system operates in the paddle wheel mode and can take the configurations previously indicated (for movement on soft soils). As can be seen from FIG. 30-33, when the propeller rotates counterclockwise with an angular velocity ω in any of these configurations, when the track sections are immersed in water and interact with the water, the normal force H and its horizontal projection T. The latter is a persistent force and provides forward movement to the left in the direction arrows V. The propulsion efficiency in rowing mode is significantly increased in the case of sections with a concave (Fig. 5) or flexible supporting surface.

 When overcoming water barriers, shoals, rifts, etc. are often found (especially in river deltas). The mover overcomes them on the go, without any readjustments in it. When moving afloat, the car is controlled in the same ways as when moving on land. But in combination with them or instead of them, a boat-type steering wheel can be used.

 The mover can have 4 or 6 telescopes. Their number may be large, but it is of little use, since while the configuration of the track contour approaches the circle. Although this is accompanied by improved ride smoothness, patency is deteriorating.

 In both the four-telescopic and six-telescopic propulsors, to ensure optimal elastic characteristics of at least some springs in the telescopes, they are made composite (of several springs that come into one another with different elastic characteristics), shaped (for example, in the form of a compression screw spring, the middle part of which has an increased pitch and increased elasticity), etc.

 In the simplest cases, the oscillations of these springs can not be damped. Such cases include movers constantly operating at low speed (in irrigation installations, in machines for working in fields littered with stones, at a speed of 0.1 km / h, in potato harvesters at a speed of 1.6-3 km / h, and t .d.).

 If necessary, damping the oscillations of these springs can be provided (depending on the specific operating conditions of the propulsion) separately or together in the following design measures. Between the coils of the spring, shock-absorbing blocks of viscoelastic material are located, which, when compressed, consume energy to produce heat. The telescope cavity is filled with viscoelastic elastomeric particles or elastic elements of a porous elastomer impregnated with a liquid (for example, compressible silicone), resulting in liquid friction. In order that these particles or elements do not interfere with the passage of the rolling bodies, they are equipped in the form of a hollow cylinder (sleeve) with longitudinal slots or grooves for these bodies, and viscoelastic elastomeric particles are enclosed in cages.

 The seals between the telescope arms are reinforced so that it can operate in the pneumatic shock absorber mode. Due to heating of compressed air (or other gas pumped into the shock absorber), such a shock absorber can be used on snowmobiles, as well as in other machines for working in cold climate zones (Zapolyarye, Siberia, Far East, Antarctica). Inside the telescope cavity, one or more conventional hydraulic shock absorbers (e.g. MKZ) are arranged in series. In particular, a new type of self-adjusting shock absorber that fits into the dimensions of a serial product can be used (Automotive Industry, 1985, No. 1, p. 13). A new single-tube shock absorber with an outer diameter of only 28-60 mm / cm can also be used (Automotive, 1985, No. 7, p. 13). Since they are protected from mechanical damage by the walls of the telescope, skirt-type safety covers can be removed from them. For better cooling of the shock absorbers in the hub and in the walls of the knees there may be cutouts or holes.

 Shock absorbers of the usual type are located outside the knees of the telescope, next to it. In the hollow hub of the mover, a rotary, for example lever-blade, shock absorber is located. Magnets are installed on the telescope’s male knee, and a winding connected to electrical resistance is installed on the female knee. During reciprocating mutual movement of the knees in the winding, an electric current is induced, heating the resistance and thereby dissipating the energy of the spring oscillations. Friction washers are located between the cheeks of the eyes in the hinge.

 If the connecting fingers in the hinges are of sufficient size and are hollow, then at least some springs in the telescopes can be twisted and placed inside them. There are no rotary shock absorbers, such as hydraulic ones.

 If not a multi-telescope is used, but in the form of a telescopic spring, then the above devices, except the first, are used to damp vibrations. Instead, between the turns of the spring is a friction, for example polyamide, gasket.

 In any case, shock absorbers can be installed not on all telescopes (hinges), but only on some, for example, located mutually opposed to the hub. Instead of a mechanical spring and shock absorber, a delayed-action hydraulic spring integrated in the telescope or a delayed-action pneumo-hydraulic elastic element can be used. If the telescope has rubber buffers that work not on compression, but on a slice, especially a multilayer one, then sometimes you can do without shock absorbers, since they themselves serve as shock absorbers.

 The machine may have a conventional suspension, as a significant part of the oscillations is damped in the propulsion itself. However, with increased requirements for smoothness (for example, in ambulances), a well-known system of automatic stabilization (regulation) of the vehicle level and / or suspension specially designed for non-circular wheels can be used (AS USSR N 1034827, class B 60 C 3/02, 1980).

 It is advisable that when driving on land, the hubs of the propulsors are located below the level of the bottom of the machine body, and when moving afloat - above it. Therefore, the suspension should provide a sufficiently large adjustable stroke of the hub. This requirement is met by the suspension on controlled rotary (lifting and lowering) link balancers with a power drive. Balancers can be both longitudinal and transverse, both single-arm and two-arm. They can be hollow with the placement of the drive hydraulic or electric motor in the hub. Although the height-adjustable (controllable) balancing suspension is optimal, other types of height-adjustable suspension, such as a vertical cylindrical type of candle used in portal cars, can also be used instead.

 In any case, for afloat movement, it is possible to eliminate or at least reduce the flow running onto the apical part of the mover, not by lifting the latter, but using hydrodynamic (water-reflecting) screens (shields, covers, etc.). As such screens, wheel housing niches, anti-mud shields, mudguards, etc. can be used. To increase efficiency, they hide behind a side screen, such as a bulwark. In the presence of such screens, the mover provides movement afloat even if not only its hub, but also he (and even the entire screen) is immersed in water. To further increase the efficiency of the working surface of a niche, a mudguard, etc., a special configuration is attached (US Pat. No. 3,688,731, class B 60 F 3/00).

 The type of suspension required also depends on the draft of the vehicle afloat. In the case of small-sitting (with a small landing of the hull) machines, it may turn out that the hub is automatically afloat above the water level, and then the question of adjusting the suspension in height disappears.

 When using this mover for the conversion of serial road vehicles, for example, off-road, their standard suspension can be used.

 As indicated above, in the mover it is possible to adjust the degree of maximum compression of the track contour in the rhombus configuration. By adjusting the compression ratio, depending on the specific road conditions, you can change the relationship between ride and patency. When passing difficult terrain, sometimes you have to temporarily sacrifice smoothness to improve patency. This mover can be both leading and non-leading, both rotary and non-rotary, etc.

 On the same machine, only four-telescopic or only six-telescopic or four- and six-telescopic propulsors can be used together (as well as in any case in combination with traditional propulsion).

 The mover is easily mounted on the standard axis (semi-axis) and is easily removed from it like a traditional wheel. The mover can be installed on the axles connected with the differential, with an overrunning clutch (including a controlled one), etc.

 The machine with this mover can be controlled by any of the known methods, for example, by turning the movers of both sides relative to the vertical axes (similar to turning ordinary wheels), braking (or accelerating) movers of one side, reversing movers of one side, or sharing these methods. When using these propulsors only instead of uncontrolled, for example, rear wheels, rotation is performed using steered wheels (front). When moving afloat, control is carried out either only by this mover, or only by the steering wheel (for example, of a boat type), or jointly.

 Movers can be mounted on standard suspensions and controlled in traditional ways. Therefore, they can be used to quickly convert existing wheeled vehicles of normal cross-country ability to cars of increased and even high cross-country ability, and in the presence of a displacement hull or floats - in amphibian. Sometimes it’s enough to replace with this mover not all wheels, but only the drive wheels.

 With four connecting devices, at least 1/4 = 0.25 of the contour length is constantly in contact with the ground, and with six, at least 1/6 = 0.17. This is more than in the prototype, in which this value is constantly equal to 0.15. With a highly compressed horizontally located rhombus, the contact length approaches 0.5 bypass length, i.e. almost equal to the corresponding value for a traditional caterpillar mover. When placing a triangle on the long side, the contact length is about 0.33 of the length of the rim, which is twice as much as in the prototype.

 This mover is environmentally friendly, lightweight, simple in design and can work in caterpillar and rowing modes (with automatic transition from one to another), providing a high fifth wheel coupling and sufficient thrust force, and therefore is almost universal. This allows you to use it in dramatically different road and ground conditions. A car with such an engine is really (and not just by name) an all-terrain vehicle.
