The invention relates to the automotive industry and is designed to equip vehicles with the purpose of short-term use in the process of operation to overcome the sections of road on which there is slipping wheels and termination for this reason, the vehicle is in motion.

Known devices and methods of their application designed to eliminate slipping, for example antiskid chain, spiking or traction control cuff, traction control devices, called lugs, rubber snow chains (Gornushkin YG Practical advice to the owner of the car. - M.: the Patriot, 1991, 207 S., ill., Fig 64, 65, 66, respectively)

The spikes on the bus ineffective on the road, covered in mud, or snow.

All the above devices and methods of their application have a common drawback: their installation is not possible in situations when the car is stopped on the uphill on slippery, uneven road, in the recesses of the road, in the rain, i.e. in situations when the antiskid device is absolutely necessary. Thus the lugs and rubber snow chains are characterized by a small length of contact with the road and therefore ineffective.

A significant drawback of these devices and methods of their use is that they zatrudnienie is set on the road in a situation stop vehicle due to wheel slip. For installation it is necessary to raise the car Jack that the bus was on the road surface, which is often impossible on rough roads with ditches, slopes and other irregularities.

The known method of overcoming sections of road with low friction, consisting installed on the drive wheels of the vehicle devices, increasing the degree of adhesion of the wheels and the road, such as traction control devices installed on the leading wheel of the vehicle, covering the part of the working surface of the tire with the outer surface of the teeth, but such antiskid device made of a metal rim of a G-shaped cross-section, curved in the longitudinal direction along the arc of a circumference of the tire, the United motionless with radially located with respect thereto by a strip having the side of the free end of the radial through groove, and a special screw, one end of which is a copy of the screws used for fastening the disk to the axis, and the cylinder, perform the screw hole for fixing the device on the screw with a plate groove and screw the wheels to the axis (Patent RF №2238855, IPC WV 15/22, VS 27/04 - prototype).

This method is implemented as follows.

Proven traction control device is sobesedyvaniyu with radially located strip rim, mounted on the working surface of the tire, which occupies a significant portion of its perimeter, with the teeth, providing a secure grip the rim with either way. Can be installed in any situation provided by the fact that rim device is installed on the upper part of the tyre which is always free. To install, for example, on the bus VAZ, Unscrew the top screw of fastening of a disk, instead install the screw and fix it with the screw drive on the half-axis. Tightly install rim device on the upper part of the tire so that the band took radial location relative to the tires, and fix the stripe on the head of a special screw fastening screw drive, turning it into a threaded hole of a special screw with the specified torque. With an installed device to go on the car forward or backward, and cross the road, experiencing slippage of the wheels. After leaving for a favorable stretch of road, the traction control device is removed.

The disadvantages of this method is the lack of contact protozanova element with a road and a substantial length of protozanova element that sufficiently strong off-road will lead to clogging of the soil of all elements of this device and will not allow travel on the section of road and paved.

The invention aims to remedy these disadvantages and to provide a method for overcoming sections of road with low friction by applying protivobuksovochnaya device with increased surface contact with the supporting surface and can be installed in any situation.

The solution of the stated problem is achieved by the fact that in the proposed method of overcoming sections of road with low friction, consisting installed on the drive wheels of the vehicle devices, increasing the degree of adhesion of the wheels and the road, such as traction control device that contains metallic bracket D-shaped cross-section, curved in the longitudinal direction along the arc of a circumference of the tire at one end of the bracket include fasteners for securing it to the drive wheel, for example a hole for installation of the bracket on the bolt that secures the disc to the hub, and the other main grundsatze elements according to the invention on the peripheral portion of each bracket place with the formation of the triangle for more gerontotherapy element with the locking plate, and additional gerontotherapy element is the base of the triangle.

In a variant of application of this method, the diameter of the location will complement the selected lug perform less than the diameter of the arrangement of the main lug.

The invention is illustrated in the drawings, where figure 1 shows a General view of the wheel with mounted grundsatzen element, figure 2 - view of the wheel from the side, figure 3 - General view of the wheel with mounted grundsatzen element and an additional element in the form of a triangle, 4 - wheel sideways with additional grundsatzen element.

The method may be implemented, for example, using a traction device comprising a metal bracket 1 G-shaped cross-section, curved in the longitudinal direction along the arc of a circumference of the tire. At the end 2 of the bracket 1 has fastening elements 3 for securing it to the drive wheels, for example the 4 hole for installation of the bracket on the bolt 5, to secure the wheel disc to the hub. At the end of the 6 main grundsatze elements 7. On the peripheral portion 2 of the bracket 1 is placed with the formation of a triangle 8 additional grundsatze elements 9 with the locking plate 10, with additional gerontotherapy element 9 is the base of a triangle 8. Between the brackets can be connected by means of plates 11.

This method is implemented as follows.

The sharp deterioration of the adhesion of the surface of the wheel with the surface of the roadway, for example, with abundant snowfall or skid roads, snow, etc is hit on the sodden dirt road, on the drive wheels of the vehicle set grundsatze elements, for example, by alternately turning the bolts 5, to secure the drive wheel to the hub, and install between the bolt and the drive bracket 1 protozanova element and screwing the bolt 5.

Gerontotherapy item significantly, in some times, due to the protrusion protosalanx elements 7, above the surface of the wheel, allows to increase the engagement of the wheel and the road surface that allows you to drive traffic to the site with a reduced coefficient of adhesion of the tires and the roadway. When he gets on the road with normal coating grundsatze elements alternately removed.

When he gets on the road with a very damaged coating, for example on a wet dirt road or in a rut, on the peripheral portion 2 of the bracket 1 place with the formation of a triangle 8 additional grundsatze elements 9 with the locking plate 10, with additional gerontotherapy element 9 is the base of a triangle 8. Additional protosalanx elements 9 can reduce the pressure of the vehicle on the ground due to the additional support surface protozanova element 9 and to increase the patency of the vehicle due to the formation of additional surface of the clutch wheel g is Tom, since the wheel contact with the ground will occur not only on the end surface of the wheel, but on the side, for example on the inner surface of the gauge.

The best is the application in the case of a long drive on roads with normal coating and brief Congress on the road without coating, with a sudden abundant snowfall, rain, when forced to ride in the rain on dirt roads.

The proposed method of overcoming sections of road with low friction will significantly reduce the size and weight protosalanx elements to significantly reduce the time and cost of installation/dismantling.
