A pattern tire which is used for a driving wheel traveling on common and high-quality road surfaces in long-distance transportation has excellent ground holding capacity and traction performance, themogenesis is low, due to the wide traveling face design, ground pressure of the tire is uniformly distributed, and the tire is endowed with excellent anti-sideslip performance.
Description
Technical field
The invention belongs to motor tire technical field, be specifically related to heavy-duty truck tyre tread.
Background technology
Because the performance of existing automobile improves constantly, and the applying of radial-ply tyre, the performance requriements of tire is improved further, particularly under running at high speed, higher requirement is proposed to the road-holding property of automobile, ground tack, driving safety, saving fuel, resistance to abrasion and low noise.Therefore the performance of design to tire of decorative pattern has vital effect.In prior art, band tire decorative pattern is numerous, is usually divided into and drives decorative pattern, guiding decorative pattern and trailer decorative pattern.Generally adopt cros-rib tread to combine with circumferential pattern to the design of tire tread pattern, the decorative pattern of design needs the performances such as consideration is wear-resisting, adherence properties, drainage, and requires that tire has stable startup and deceleration and stopping performance.Existing market requires that motor tire is green, environmental protection, the large quantifier elimination that domestic and international Tire production producer carries out in Pattern Design, and to reaching low noise, rolling resistance is low, the in-use performance of the excellences such as safety performance is high, long service life.When designing tyre tyre surface, tread designer needs to combinationally use pattern block and groove, to optimize the tread properties of tire.
Under normal circumstances, circumferential pattern has good guidance quality and drainage performance, and noise of running at high speed is low, rolling resistance is little; Cros-rib tread driveability is more excellent than circumferential pattern with deceleration and stopping performance, but lateral sliding is larger than circumferential pattern, and noise is high, rolling resistance is large; Dual purpose tread pattern has the advantage of above two kinds of decorative patterns concurrently, is to ensure tyre performance, often by cros-rib tread and circumferential pattern with the use of.Compared with the Light-duty Vehicle such as autotruck and car, control ability, the treadwear degree of road pavement require higher.Therefore, how to research and develop a kind of novel heavy-duty truck tyre tread, make it have and there is more fully performance, have important practical significance.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide heavy-duty truck tyre tread, tread contour is applicable to autotruck whole steel wire radial tyre, uses best at the axle drive shaft of vehicle.Decorative pattern is crisscross mixed type decorative pattern, can improve the road-holding property of vehicle, and comfort property is good, low noise.
The technical solution used in the present invention is:
