Known antiskid device mounted on a driving 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 consists of a metal rim of a G-shaped cross section curved in the longitudinal direction along the arc of a circumference of the tire, United still 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 in the head of the threaded 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)
The disadvantages of this invention is the significant 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 to go on the road with hard surface.
The closest in technical essence (prototype) is antiskid device (patent No. 2449896)containing a metal bracket D-shaped cross-section, curved in the longitudinal direction along the arc of a circumference of the tire. On one end of the bracket is made 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. On the peripheral part of the bracket is placed with the formation of the triangle for more grundsatze items fiksiruyuschimi, additional gerontotherapy element is the base of the triangle.
The disadvantages of this invention is the manufacturing complexity and bulkiness of the structure.
The technical result of the invention is to simplify the design and reduce the time of installation in any situation when the vehicle is on any road due to the slipping wheels.
The technical result is achieved by the fact that in the proposed antiskid device grossetana element made in the form of synthetic rope, the free end of which is rigidly fixed metal strip with perforations, interconnected by springs.
The invention is illustrated by drawings, where figure 1 shows a General view of the wheel with mounted grundsatzen element (section across); figure 2 type wheel side; figure 3 is a side view (in difficult road conditions).
Antiskid device includes synthetic rope 1, at the free end of which is rigidly fixed metal strip 2 with perforation, interconnected by means of a spring 3 and mounted on the driving wheel 4 with the formation of protozanova item 5.
The proposed device operates as follows.
The sharp deterioration of the adhesion of the surface of the wheel 4 with the road surface p of the pilot, for example, with abundant snowfall or skid road is snow falling on the wet dirt road, the drive wheels of the vehicle are installing synthetic ropes 1. Each rope is passed first through one window of the wheel rim with a stretch to education protozanova element 5. Then the rope in the same way several times passed in the opposite window of the wheel rim. The free ends of metal strips 2 are inside the outside rim of the wheel. By means of a spring 3 they are drawn together, forming a traction control device, ready to work. When he gets on the road with normal floor antiskid device alternately removed.
In the case of very complex traffic conditions on the wheel can be installed several traction devices (figure 3).
The optimal application in the case of a long drive on the road without coating, with a sudden abundant snowfall, rain, when forced to ride in the rain on dirt roads. The proposed construction protosalanx elements will significantly reduce the size and weight protosalanx elements to significantly reduce the time and cost of their installation and removal.
Antiskid device containing mounting and grundsatze elements, characterized in that grossetana ELEH the UNT made in the form of synthetic rope at the free end of which is rigidly fixed metal strip with perforations, interconnected by springs.
