RU2266825C2 - Tire with abrasive elements on tread - Google Patents

Abstract

FIELD: automotive industry.

SUBSTANCE: proposed tire has V-shaped grooves of tread with top pointed forwards, with interval up to 50 mm and greater, and width and depth up to 20 mm depending on mass of vehicle (bus, truck, aircraft). Tire is provided with V-shaped abrasive element fitted in and made of abrasive material consisting of silicon carbide, titanium carbide, fillers and binders. Lower layer of element is made of more cheap material, particularly, of titanium alloy.

EFFECT: increased antislip and wear-resistant properties of tire tread.

Description

Wheel transport - buses and heavy vehicles are widely used for transporting passengers and goods, as well as in the defense industry. The safety and reliability of which are stringent requirements, because life and health of people and preservation of material values depend on their operational qualities.

The running gear, especially the wheels, as organs for converting rotational motion into translational motion, developing large inertial forces of the cargo masses, largely determine road safety. The increase in cargo mass and speed are accompanied by a large inertial force. The possibilities of slowing down this force and stopping the moving wheeled transport depends on the design and material used on the running surface of the tread tire. To do this, various patterns with grooves and protrusions are made on the tread, studs are made of carbide materials. Patents of the Russian Federation No. 2098284 (IPC: B 60 on 11/14. Bull. No. 34, 12.97), No. 1071460 (Bull. No. 5, 02/07/84), copyright certificates: No. 495218 (Bull. 46, 15.12.75) , No. 495218 (Bull. No. 46, 12.15.75) are aimed at solving the traction and braking properties of the tire tread.

In the prototype described in the patent of the Russian Federation No. 2098284, spikes are used as tire anti-skid elements, which are embedded and fixed on the basis of the tread belt.

Provided in the prototype and in the above inventions, technical solutions partially improve the anti-slip, traction properties of the tire. But on buses weighing more than 15,000 kg and on heavy vehicles and heavy aircraft on the run, they are not effective, in addition, prematurely wear the tread surfaces.

The purpose of the present invention is to provide the wheels of buses, trucks and heavy aircraft with reliable, high anti-slip and wear-resistant qualities that ensure the safety of passengers and the safety of expensive equipment and valuable goods.

The goals are achieved in that as a material that creates increased traction, braking and other positive qualities, an abrasive material is used, consisting of silicon carbide, titanium carbide, fillers and binders, in particular abrasive material according to copyright certificate No. 594149 (IPC : From 09 to 3/14, Bull. No. 7, 02/25/78) or on the basis of abrasive material and a titanium alloy widely used in the national economy.

It is important that the abrasive material has an emery quality, and that the titanium alloy is used to form the non-working part of the element.

The invention provides for the introduction of V-shaped elements of abrasive material (and of titanium alloy) on the V-shaped grooves of the tread with the top forward, counterclockwise. Elements are formed in abrasive production, dimensions: width, thickness depend on the features of the wheel, and can have a thickness and width of 20 mm or more and a span angle of generators (wings) of 45 degrees or more. The interval between the V-shaped elements can be up to 50 mm or more, but able to take on all the grip load on the ground. The lower, non-working layer of the element, to reduce the consumption of expensive material, may consist of a titanium alloy that does not allow overheating of the rubber base of the tread. The reliability of their introduction into the grooves of the tread is provided by the scope of the V-shaped abrasive elements.

A tire with abrasive elements on the tread is illustrated by drawings, where FIG. 1 shows a general view of tire 3, FIG. 2 shows a V-shaped abrasive element 2, tread 1, tire 3, forming surface 4, lower surface 5, width 6, thickness 7 item.

V-shaped elements 2 are embedded in the grooves of the tread 1 with a 2-3 ^x mm protrusion, so that the surface of the treadmill 1 (new) is not rubbed on the hard surface of the road. The wings of the forming elements have a convexity corresponding to the radial rounding of the tread 1 of the tire 3. A tire with abrasive elements on the tread is used until the clamping force of the tread grooves is weakened, and by loosening the clamping force, glue made of composite materials can be poured into the grooves of the abrasive elements, and after a certain wear of the forming tires abrasive element can be used on a less responsible mode of transport.

Claims (1)

Tire with abrasive elements on the tread, characterized in that, in order to increase the anti-slip and wear-resistant qualities of the tire tread, onto the V-grooves of the tread with the apex forward with an interval of up to 50 mm or more, width and depth up to 20 mm, depending on the cargo weight of the transport means (bus, truck, plane) V-shaped abrasive elements are introduced, made of abrasive material consisting of silicon carbide, titanium carbide, fillers and binders, and the lower layer of the element is made of cheaper m material, in particular titanium alloy.
