Steel disc for truck and bus tires and tire manufactured by using the same

Abstract

A steel disc for truck and bus tires is integrally a three-dimensional design, which is reflected in a three-dimensional space of length, width and thickness; the steel disc is designed as wavy curved planes in both two vertical directions of a length direction and a width direction of the steel disc; in the width direction, the wavy curved plane extends to a position which is 2-5 mm from the edge of the steel disc; in the length direction, the wavy curved plane is arranged at a middle part and accounts for 70-95 % of the whole length; two end parts of the steel disc are designed as planes; in the length direction of the steel disc, each part is designed with unequal length; and in the width direction of the steel disc, each part is designed with unequal width. In a tire tread manufactured by using the steel disc, a plurality of three-dimensional grooves, which are manufactured by using the steel disc as a mold, are formed in each side pattern block and each should pattern block; and angles between the three-dimensional grooves and the central line of the tire tread are 35-90 DEG. According to the invention, as the snow coefficient of a tire manufactured by using the steel disc is 1.25-2.43, excellent braking and driving performances of the truck and bus tires on ice snow covered pavements or snow slush pavements are ensured.

Description

technical field [0001] The invention relates to truck and bus tires used on ice, snow or slush roads, in particular to a steel sheet and a tire tread pattern structure made of the steel sheet. Background technique [0002] Ordinary all-steel radial truck tires used by trucks and buses are prone to problems such as skidding and increased braking distance due to the reduced friction coefficient between the tire and the ground when driving on ice, snow or slush roads, which have a great impact on the safe driving of the vehicle. At present, the anti-skid measures used by truck and bus tires on ice, snow or slush roads are mostly winding anti-skid chains on the tire surface or placing straw mats on the road surface, throwing snow melting agent, industrial salt, etc., which not only damage the tires, but also take time and effort. Great impact on the environment. The driving of the vehicle is mainly guaranteed by the friction between the tire and the ground to provide driving an...
