technical field

The utility model relates to the technical field of tires, in particular to a radial tire for mining.

Background technique

Tires are annular elastic rubber products that roll on the ground and are assembled on various vehicles or machinery. Usually installed on the metal rim, it can support the body, buffer the external impact, realize the contact with the road surface and ensure the driving performance of the vehicle.

With the development of open-pit mining and engineering construction in China, medium-sized dump trucks are widely used in mine transportation due to their large load capacity and strong applicability. The tire used in medium-sized dump trucks is a radial tire. At present, in mine transportation, the radial tires used in medium-sized dump trucks are basically composed of outer carcass layer, inner carcass layer, reinforced rubber and steel wire layers in the inner and outer carcass layers. This is achieved by reinforced rubber. Due to the large force of the reinforced rubber, the tire is prone to damage. Therefore, we urgently need to design a radial tire to solve the above problems.

There are blocks, and the outer carcass layer and the inner carcass layer are filled with a reinforced rubber body connection.

When the tire is subjected to a large force, a part of the force is applied to the whole composed of the reinforced rubber body and the belt layer, and deformation occurs, and a part of the force is applied to the whole composed of the elastic arc layer and the reinforced rubber body, and the deformation occurs. Through the joint action of the above two, when driving on complex roads, the shape variable of the tire is reduced, the probability of internal tire blowout is reduced, and the joint force of the elastic arc layer and the reinforced rubber layer is reduced accordingly. A reinforced rubber layer conforms. The design of the utility model solves the problem that the existing radial tires for mines are easily damaged due to the fact that the radial tires are easily damaged during the process of deformation and recovery of the radial tires only by reinforcing the rubber.

The exposed toe wire is dangerous.

(3) The utility model is made of relatively thick steel wire through the belt layer. The working road of mine tires is much more complicated than that of ordinary tires, and the thicker steel wire has the effect of strengthening mine tires.

(4) The utility model is made of elastic steel through the elastic arc layer, and the angle opposite to the elastic arc layer is π/2. The arc-shaped layer made of elastic steel has the advantages of stable structure and strong deformability. The angle opposite to the elastic arc-shaped layer is π/2, which avoids the bending angle of the arc-shaped part being too small and is not easy to deform, resulting in a relatively low tire structure. Hard, with low cushioning capacity.
