Tread pattern for truck mine tyre

Abstract

The invention discloses a tread pattern for a truck mine tyre. The tread pattern comprises transverse corrugated main pattern grooves which are circumferentially and uniformly distributed in a tread. Transverse corrugated large pattern blocks are formed between the adjacent transverse corrugated main pattern grooves. Each transverse corrugated main pattern groove comprises a crest pattern groove body and a trough pattern groove body which are located in the left side and the right side of the center line of the tread. The crest pattern groove bodies and the trough pattern groove bodies of the adjacent transverse corrugated main pattern grooves are connected through oblique auxiliary pattern grooves which are the same in oblique direction. The oblique auxiliary pattern grooves divide the corresponding transverse corrugated large pattern blocks into left small pattern block bodies and right small pattern block bodies. The centers of the bottoms of all the transverse corrugated main pattern grooves are provided with reinforcing rib blocks. The reinforcing rib blocks are connected with the small pattern block bodies opposite in oblique direction of the adjacent transverse corrugated large pattern blocks. The transverse corrugated main pattern grooves are wide and deep while the oblique auxiliary pattern grooves are narrow and shallow. The tread pattern for the truck mine tyre is high in ground gripping force, enough in rigidness, small in creeping temperature rise, good in heat dissipation performance and long in service life.

Description

technical field [0001] The invention relates to an engineering machinery tire structure, in particular to a tread pattern of a truck mining tire. Background technique [0002] Truck mining tires, due to their heavy load, large traction, complex road conditions and other factors, in order to take into account the requirements of grip, wear resistance and heat dissipation, the tread of mining tires usually adopts different types of patterns structure to suit its performance requirements. [0003] For example, the tread pattern of the most common truck mining tire adopts wavy pattern grooves, and the pattern grooves are arranged at intervals on the tread surface (in the axial direction of the tire) to divide the tread into circumferentially uniform patterns. Block, this kind of truck radial tire has the following defects found in use: [0004] 1. The direction of the pattern groove is more in the horizontal direction and less in the vertical direction, which makes the tire's ...

AI Technical Summary

Problems solved by technology

[0004] 1. The direction of the pattern groove is more in the horizontal direction and less in the vertical direction, which makes the lateral grip of the tire insufficient and easy to slip

[0005] 2. Each pattern block is relatively independent and has a large area, which is easy to creep and cause temperature rise and slow heat dissipation, resulting in thermal peeling damage to the tire
