Problems solved by technology

The sidewall of the tire on the side half of the outside of the vehicle is highly likely to be scrapped due to severe wear or cutting and puncturing by sharp objects, and when the tire encounters such damage, it will not only reduce the service life of the tire, but also waste The raw materials are not only increased, but also the production and use costs of the tire are increased; secondly, the degree of wear on the left and right halves of the tire is inconsistent, which will cause left and right uneven shapes that damage the performance of the tire, thereby affecting the stability of the tire , there will be a rollover accident in severe cases

Embodiment Construction

[0014] Such as figure 1 It is a sectional view of a tire in the width direction according to the present invention. A hypothetical axis of symmetry 1 divides the tire into two halves, each of which includes a crown, a shoulder, a sidewall and a bead from top to bottom. The upper surface of the crown is the tread 4 of the tire. The tire has an asymmetrical profile in cross-section, that is, the above-mentioned two half areas are asymmetrical with respect to the axis of symmetry 1, and one half area is set as a normal sidewall 3-2, the other half area is the reinforced sidewall 3-1, the thickness of the reinforced sidewall 3-1 measured in the tire width direction is greater than that of the normal sidewall 3-2 on the same plane relative to the tire width direction The thickness measured above. For this embodiment, the thickness measured at the horizontal axis 2 of the normal sidewall 3-2 of the tire is 8-15 mm, while the thickness measured at the horizontal axis 2 of the reinfo...

Abstract

The invention discloses a tire that comprises two half sections which are divided by a symmetry axis of the tire; wherein, the two half sections mainly consist of a tire tread and a tire side and are different in that the two half sections are asymmetric, that is to say, the half section of one side is a normal tire side and the half section of the other side is a strengthening tire side; the thickness of the strengthening tire side measured in the direction of the tire width is bigger than that of the normal tire side on a relative surface measured in the direction of the tire width. The tire of the construction machinery is particularly suitable for being applied to construction machinery vehicles running under a mine or pit and is characterized by long service life and raw material saving.

Description

(1) Technical field: [0001] The invention relates to a tire, in particular to a tire. (two) background technology: [0002] Construction machinery tires are installed on construction machinery vehicles for special operations, such as loaders, bulldozers, excavators, land levelers, road rollers and stonework machines. The driving speed is not high, but the road conditions used are harsh and the load performance requirements are high. Especially for construction machinery vehicles used in mines or underground mines, the working environment is narrow tunnels such as coal mines and tunnels. When the vehicle is running inside, the tire wall on the outer side of the entire vehicle often touches the tunnel wall. And easy to wear and cut. If according to the existing tire design scheme, the tire is designed so that the thickness of the sidewalls of the left and right halves separated along the axis of symmetry is equal, then the sidewalls of the side half of the tire located on th...
