Off-the-road tyre tread pattern

Abstract

The invention discloses tread patterns of construction machinery rubber tires and the patterns comprise transverse tread blocks and tread grooves; wherein, the transverse tread blocks and tread grooves dislocate in the circumferential direction and take a center line of the tread as the reference to be antisymmetric; the transverse tread grooves are stripy tread grooves which are arranged from the place close to the center line to a tire shoulder and extend to the tire side, and each tread block is repeatedly allocated into the form of equal interval, and upper groove edges and lower groove edges of the tread grooves are both of the shape of S and the curvature of the upper groove edges is smaller than that of the lower groove edges; the upper groove edges at groove heads of the tread grooves are convex outside a groove and the upper grooves edges of the rest part on a tire tip are concave inside the groove; the lower groove edges which are in the corresponding projection length of the upper groove edges which are convex outside the groove are concave inside the groove and the lower groove edges in the corresponding projection length of the upper groove edges which are concave inside the groove are convex outside the groove; the upper groove edges and lower groove edges of the tread grooves at the tire side are two straight lines which are approximately parallel. The tread patterns of construction machinery rubber tires are high in self-cleanness and good in wear resistance and piercing resisting performance and are particularly suitable for skew tires used in engineering vehicles such as dump trucks, bulldozers or wheel loaders.

Description

(1) Technical field: [0001] The invention relates to a tire tread pattern, in particular to an engineering machinery tire tread pattern. (two) background technology: [0002] Depending on the purpose of the tire and the environment in which it is used, the tire is required to have different performances. For example, for high-speed car tires, the heat dissipation and grip performance of the tire are high, but the requirements for other such as traction performance are not very high; Excellent handling stability, suitable for driving in wild road conditions and widely welcomed by off-road vehicle drivers, but its wet road skid performance is worse than other types of tires. The performance of the tire depends largely on the tread structure of the tire in direct contact with the ground. The tread structure of the tire is mainly the tread pattern, which is composed of grooves and blocks. It can be seen that the design of the tire tread pattern has a great influence on the use...

AI Technical Summary

Problems solved by technology

It can be seen that the design of the tire tread pattern has a great influence on the use of the tire, that is, the environment in which the tire is used. Driving under the conditions of driving, and there are a lot of sand, gravel and silt on the driving road, so it is necessary to have a tread pattern with strong self-cleaning ability, ideal wear resistance and puncture resistance, and will not cause stress concentration and lead to chipping and chipping. However, the tread pattern of existing construction machinery bias tires is generally easy to trap sand and stones, easy to collapse, not resistant to cutting, not resistant to puncture and not wear-resistant, which not only causes early damage to the tire, but also affects To the maneuverability of engineering vehicles, it cannot meet the requirements of the above-mentioned engineering vehicles
