Types of tires

Toroidal tubeless tires. Tubeless tires structurally simpler chamber. Puncture the tire air comes out of it slowly, allowing the driver time to stop the car and avoid accidents (increased safety). Tubeless tires have several specific elements: a sealing layer with a thickness of 1.5-3 mm, the sealing rubber and rim board a special form of valve. Sealing layer has high air impermeability and is made of denser varieties of rubber such as butyl-rubber, for example, etc. As a consequence of a more moderate temperature conditions at work and use the best varieties of cord average lifespan of tubeless tires are 20% higher than conventional tires, in turn spares maz 15% more durable than others. Tyres type R and RL. Bus Type R and RS fundamentally different from conventional construction of a new frame and belt. These tire carcass has a radial arrangement of cords and brekerny zone - the hoop. Filaments a skeleton only accept radial loads, which reduces the number of layers of cord almost doubled and increased to 25-30% of the radial elasticity of the tires. Tangential forces are transmitted malorastyazhimym breaker (bus type F) or movable in two or three rings tread (tire of the RS), which are to increase the tangential (circumferential) stiffness of reinforced steel cord. As a result of tire under consideration (eg, bus type F) as compared to conventional tires have a higher (1.5-2 times) the term of service, lower losses in the rolling wheels and fuel consumption (8-12%), more favorable temperature mode (the heating temperature is reduced by 20 - 30 ° C). With respect to the mass equivalent of the R bus standard, but tires of the RS even more difficult. Removable ring mounted on the tire of the RS in nenakachannom state. After inflating tires ring firmly adhere to the surface of the profiled groove skeleton. The main drawback of the RS tires - the possibility of jumping removable rings with a decrease in air pressure in the tires while driving on bad roads. Wide-bus. Wide-tire relative to the toroid, with an equal outer diameter have a greater capacity and better operational and technical quality. They are lighter than conventional double (for the rear drive wheels) toroidal tires at 10-15%. The use of wide-tire reduces rolling resistance, vehicle, reduces fuel consumption and improves throughput (due to the wider tread of the tread and a better contact with the road) and resistance, increases the average vehicle speed. Arched bus. Arched bus used as a means of increasing cross-trucks. His name arched tires received from the profile form. The width of the arched profile tires is 2-2.5 times higher toroidal profile tires. Arched tires at work have large radial deformation and transmit large torques, so they are made of high strength nylon cord and rubber based on natural rubber. Tread depth of 30-60 mm, 100-250 mm Grouser step. Arched tubeless tires are made. Low internal pressure, wide profile frame and elastic arch tires are responsible for a large area of ??prints at 1.5-2 times the area of ??toroid tire prints, and therefore much less pressure in the contact. As a result, and due to the presence of large increases permeability Grouser cars. For the motion on a hard road in the middle of the tread has a running track. Good softening and damping properties of the arched tires improve the conditions of the suspension vehicle. Pnevmokatki. Application pnevmokatkov enables dramatically improve the throughput of cars on soils with low bearing capacity (snow, loose sand, marsh, etc.). Pnevmokatki have a greater width of the profile with a relatively small and very small bore diameter. Internal adjustable air pressure in pnevmokatkah very low (20-70 kPa). This air pressure and width provides more contact area and good traction. Slim frame and a small air pressure in pnevmokatke make it resilient, therefore he wraps bumps well and resists shock, at the same time a lot easier parts KAMAZ tolerate changes in temperature. A significant amount of air in pnevmokatkah and their high flexibility allows in some cases to abandon the elastic elements in the suspension vehicle. Tire pressure-regulated. Tire pressure-regulated differ from regular toroid tire increased by 25-40% of section width less than 1.5-2 times the internal air pressure, reduced stiffness due to frame a smaller number of layers of cord, high elasticity of the tread and the lack of a spool valve. Tires with adjustable air pressure mounted on all terrain vehicles, which can be installed spares ZIL. The tread has a large, widely spaced lugs, the depth is equal to 20-30 mm. Lugs are cut by transverse grooves for greater flexibility and better self-cleaning by scoring them with mud and snow.
