Description

The device and design of the present invention are shown in figures 1, 2, 3, 4, 5, 6.

Figure 1 shows: 1 - cap cover assembly, worn on the tire of a car wheel. 2 - power web (rim) of the casing - the main power connecting part of the casing. The canvas (rim) of the casing is made of steel (ordinary or improved), all the components of the casing are attached to it. It is made from a sheet of steel horizontally at a length equal to the diameter of a given car wheel, and a width equal to the width of a car wheel, 5-6 mm thick. It can be monolithic (along the length of the diameter of the wheel and its width), at the ends of the locks for connection and connector, or consist of sections - 2-4 interconnected locks at the ends of the sections. Figure 1 shows a cap casing consisting of 2 halves that are connected by locks. The canvas (rim) of the casing, like a horizontal metal sheet, is convex (not much) so that the canvas (with spikes) rests on the tire tire tread (tread). Thin steel sidewalls are riveted to the web (rim), which are adjacent to the side surfaces of the tire. The sidewalls (laps) are lowered on the sides of the tire tires to 1/3 of its height. This is important for the stable operation of the casing on the wheel tire. The power sheet (rim) of the casing is crimped by the diameter of the wheel (round). Upper spikes and lower spikes or caterpillars are attached to the power web (rim) with bolts with nuts, rivets and washers. The halves of the fabric (rim) of the casing are connected by two locks (hinges with a bolt and nut). Hinges (locks) are riveted to the web (rim) in three places - at the top and along the sides of the sleeve casing (also sections).

The power blade (rim) of the casing, having on itself the upper spikes and lower spikes or caterpillars, fully ensure the principle of the work of the union device to ensure the all-terrain vehicle tires of the wheels of the car. The upper spikes are pressed into the tire of the wheel during mass load, adhering firmly to it, the load is transmitted to the lower spikes or tracks, which also firmly adhere to the ground, which ensures the all-terrain vehicle tires with slip-on casings to overcome heavy ground roads (sand, ice, snow etc.). The casing, made of metal, fully provides the casing with special durability and trouble-free operation of the casing on the tire of the wheel.

Figure 1: 3 - the upper spikes (height 8-10 mm), are designed to create a strong and reliable grip of the casing with the wheel of the car. The mass load presses on the car wheel, the upper spikes are pressed into the tire cover (tread) and couple the casing to the wheel tire. The spikes are made of any steel, preferably of improved steel (they will work longer), they are attached to the casing blade (rim) either with external thread bolts, or rivets with washers, or with lower studs with headless bolts, or are cast in one piece with the casing power sheet (rim) .

In Fig.1: 4 - lower spikes or tracks (Fig.1 - casing with tracks), are designed to create a coupling of the cover casing with the ground. The mass load presses on the web (rim) of the casing, which presses on the upper and lower spikes of the track. The upper spikes adhere firmly to the tire, pressing into the tire rubber, and the lower spikes or tracks are pressed into the ground and firmly adhere the tire to the ground and a stable cross-country overcoming of heavy soils occurs. The lower spikes or caterpillars are made of any steel, 12-15 mm high, they are attached to the web (rim) with bolts and nuts or riveted with rivets with washers, which are then countered. In Fig.1: 5 - sidewalls (flaps 1/3 of the height of the tire), are intended for additional parallel, duplicating, reinforcing the fastening of the casing on the tire of the wheel. They are made of thin metal (sheet), inside to the tire are small spikes that are pressed into the tire sidewall rubber. The sidewalls (laps) are firmly pressed (pressed) into the tire rubber, enhancing the overall grip of the casing with the car’s tire. The sidewalls (laps) on the tire of the wheel are convex along the contour of the tire in order to better fit it. So that the inner spikes of the sidewalls (laps) are pressed into the rubber of the sidewalls of the tire, they are made at the angle of attachment of the sidewalls (laps) to the canvas (rim) of the casing, and then they constantly pressurize the tire sidewalls with great interference. Other fasteners are not needed, the design is successful and very reliable.

In Fig.1: 6 - tire (tread) of the tire of the wheel, where the upper spikes are pressed and engage the tire with the lower spikes (or tracks) and the ground.

Figure 1: 7 - locks of the connection and connector of the canvas (rim) of the casing. They are designed to connect and disconnect (connector) the power web (rim) of the casing on the tire when it is put on and removed from the tire:

1) if the web (rim) of the casing is monolithic, then the locks are placed at the ends of the power web (rim) of the casing,

2) if they consist of two halves, then locks (4 pieces) are placed at the ends of the halves of the power web (rim),

3) if the casing consists of sections (3-4 sections), then locks are placed at all ends of the casing section.

The main locks of the connection and connector of the power web (rim) of the casing are locks-hinges (by the type of door, window hinges). The metal loop of one end of the casing blade (rim) enters the other loop of the other end of the casing blade (rim), insert bolts into the holes, tighten with nuts and counter. The locks themselves loops with their planks-cases are riveted to the ends of the web (rim) of the casing. You can use ring locks, ring locks, snap-in locks (like parachutes).

In Fig.1: 8 - tire wheel of the car.

Figure 1: 9 is a housing (drum) of a car wheel.

Figure 2 shows the sidewalls (flaps) of the casing, their device and features.

In Fig.2: 2 - sidewalls (flaps) of the casing, attached to the canvas (rim) of the casing. Their feature is that, made at an angle to the sidewalls of the tire wheels and having spikes, they firmly hold the casing on the wheel tire. In figure 2: 10 - the sidewalls (laps) on the tire of the wheel have a bulge along the contour of the sidewalls of the tire, so that they fit better on the rubber of the tire. In Fig.2: 3 - on the inner sides of the sidewalls (inlets) there are spikes that fit snugly against the sidewalls of the tire rubber, having angles of inclination towards the sidewalls of the tire wheels (upper spikes).

Figure 2: 4 - the lower spikes of the casing. When putting the casing on the tire of the wheel, the sidewalls (laps) are squeezed to the sides of the sidewalls of the wheel tire, and when released, they are pressed tightly into the rubber of the sidewalls of the wheel tire. The sidewalls (laps) start from the web (rim) of the casing, go at an angle to each other and taper at the end - this design principle ensures that the sidewalls (laps) tightly compress the tire rubber of the wheel.

Figure 3 shows in section how the casing is held (in principle) on the tire of a car wheel during movement. Figure 3: 9 - wheel housing, figure 3: 8 - wheel tire, figure 3: 6 - tire cover (tread) of the wheel tire, figure 3: 3 - upper casing spikes, figure 3: 4 - lower casing spikes or caterpillar casing, figure 3: 5 - sidewalls (laps) of the casing, which are pushed onto the sidewalls of the tire wheels 1/3 of the height of the tire wheels.

The principle of operation of the casing during movement - the upper spikes under the weight-load are pressed into the tire tire tread, creating a strong grip of the casing and tire of the wheel, through the web (rim) of the wheel, the mass-load presses on the lower spikes or tracks, which are also very firmly engaged with soil, and the car’s wheel becomes cross-country.

Figure 4 shows the caterpillar section of the casing and its attachment to the casing web (rim). Figure 4: 11 - soil track-mounted caterpillar hook, made of steel, cone-shaped, has a platform, as a support and for mounting. In Fig.4: 12 - the track platform as a support for the caterpillar hook and for attaching the track to the canvas (rim) of the casing. In Fig.4: 2 - the canvas (rim) of the casing, on which all the components of the union casing are mounted. In Fig.4: 13 - the mounting bolts with nuts, counter, or rivet pins with washers, fasten the hooks of the tracks to the canvas (rim) of the wheel. Caterpillar hooks on the slats can be mounted in sections in 3 places, at the ends and in the middle.

Figure 5 shows a fragment of the mounting and device lower (upper) spikes. In Fig.5: 4 - the lower spikes (upper, less in height), are made of steel. In Fig.5: 14 - washers or spike strips (if stud sections, then strips are used). In Fig. 5: 2, the web (rim) to which the lower (and upper) spikes are attached. In Fig. 5: 15, the bolt pins without heads and nuts, at both ends have an external thread, the spike has an internal thread (as shown in Fig. 5), and the upper and lower studs are screwed onto the bolt rods (pins) and are locked through holes in rods and spikes. The studs are very secure.

Figure 6 shows schematically the lock of the connection and the connector of the sleeve casing in sections as a whole. The lock is a hinge-hinges that enter one another, with holes in which a bolt is inserted for their fastening. Fig.6: 16 - the case of the lock-loop. 6: 17 - rivets connecting the lock with a cloth (rim) of the casing. Fig.6: 18 - hinges on the axes, are attached to the castle body, holes in them. Fig.6: 19 - holes in the hinges for bolts. Fig.6: 20 - a bolt securing the hinges when they enter each other. Locks for connection and connector of the casing can be bolted, ring with bolts, snap. The bar goes into the lock case and snaps into place using a spring. Locks are attached at the ends of a half or section of the casing, in 3 places - at the top (cloth-rim) and on the sides of the casing-sidewalls (laps) on the left and right.

WORK OF AN ATTRACTIVE SHOES.

When driving a car with a cover, the mass-load of the car presses on the canvas (rim) of the casing. The upper studs firmly adhere to the tire (tire) of the wheel, pressing into the tire rubber. The mass-load pressure through the web (rim) of the casing is transmitted to the lower spikes (or tracks) of the casing, and under load they firmly adhere to the ground. And the wheel with the casing acquires all-terrain, working very reliably to overcome the heavy soils of roads, snow, ice, sand, etc.

NOTE. Production technical and technological solutions in the manufacture of cross-country all-terrain device:

1. Factory production and manufacturing of all-terrain cover cases for automobile tire tires is the most rational and cheap, because all the components and parts of the cover device will be cast in molds or other equipment. All will be immediately cast - the web (rim), the upper spikes, the lower spikes (or ground hooks of the caterpillar type) directly on the cloth (rim) of the casing, the sidewalls (laps) of the casing will also be molded together with the cloth (rim) and their inner spikes adjacent to the sidewalls of the tire wheels. At the factory, it is also rational and very profitable to use stamping for the manufacture of sleeve covers for all components of the sleeve cover. After casting, the appropriate technical processing of the parts of the sleeve cover.

2. To produce and make cap metal casings in workshops - this will be more expensive than at the factory. It is necessary to apply welding and stamping, as well as turning and metalwork. The canvas (rim) of the casing must be cut from a sheet of steel or stamped. For the upper and lower spikes (or tracks), you need to make holes for attaching them to the canvas (rim) of the casing. Sidewalls (inlets) of the casing - first stamp the inner spikes on the sidewalls (inlets), then the left and right sidewalls (inlets) on the tire tires in diameter to weld to the canvas (rim) of the casing. Welded at an angle (taper to the bottom for interference on the tires). The production of casings in workshops, although it will be more expensive than at the factory, can provide a return on investment due to the individual approach to the wheels of a particular customer, as well as due to the increased quality and elite of the materials used (also at the request of each specific customer).

3. The issue of the versatility of the cover of automobile covers - universality will be double - separately for the wheels of passenger cars and for the wheels of trucks. The universality of the length of the cover casing is solved (the length of the casing according to the diameter of the wheel is 1200 mm, 1500 mm, etc.) in that the cover casing can be collapsible, consist of 2 or 4 sections, and additional sections enable the length of the casing per wheel pick up from a passenger car or truck using sections of the casing - connecting or disconnecting them for the desired length along the diameter of the tire of the wheel of the car. The width of the casing, as universal, is solved as follows for casings only with spikes. With tracks, the width of the casing should be constant. The power sheet (rim) of the casing is cut in length (sections or parts of the casing), and compression springs are inserted between them, or over the entire diameter (length) of the casing.

In this case, the upper and lower spikes will be located along the length (diameter) of the casing (respectively, the width of the tire tires) separately in two rows.

The manufacturing technology of universal casings, as shown above, in a factory way or in workshops - casting, welding, stamping, turning and metalwork for the manufacture of casings. In order to put the casing on the tire of a larger wheel width, it is necessary to pull the casing with effort on the tire and sidewalls of the tire of the wheel, the compression springs will be wide and the casing will be firmly put on the tire of the car wheel. In this case, the casing with compression springs - a blade (rim) cut along the length of the blade - will also be firmly attached to the tire of the wheel and ensure its cross-country ability.
