Description

The tread contour of all-steel load-bearing radial tire

Technical field

The utility model is related to automobile tire decorative patterns, and in particular to a kind of tread contour of all-steel load-bearing radial tire.

Background technology

With the fast development of auto industry, the demand of all-steel load-bearing radial tire is on the increase, and influences tire Performance is mainly the design of tread contour.The design of tread contour will according to wheel position, road conditions, the demand of vehicle and client, And to meet the conditions such as low rolling resistance, low noise, wearability.Technical research shows, it is generally the case that annular ribs has good Good guidance quality and drainage performance, low noise when running at high speed, rolling resistance is small；The driveability and braking of transverse pattern It can be more excellent than annular ribs；The lateral sliding of transverse pattern is bigger than annular ribs, and the high noise of transverse pattern, rolling resistance Greatly；Dual purpose tread pattern has both the advantages of both the above decorative pattern, to ensure the comprehensive performance of tire, often by transverse pattern and longitudinal flower Line is used cooperatively.

All steel load tyre tread is broadly divided into driving decorative pattern, guidance type decorative pattern and trailer decorative pattern in the prior art, The driving decorative pattern of truck generally use, good brake force, driving force can preferably be competent at the load-carrying work of truck Make.The tread structure of tire is generally made of pattern block and groove.General driving decorative pattern is lateral circumferential on tire tread Several pattern blocks of arrangement, groove lateral direction penetrating, although tire increases with contact area of ground, the road for being suitble to road conditions poor Road, but noise is big, rolling resistance is big, and lateral earth-grasping force is weaker, and wet-sliding resistant performance is poor.

Invention content

In order to overcome existing all steel load tire noise big, rolling resistance is big, and lateral earth-grasping force is weaker, and wet-sliding resistant performance difference is asked Topic, the utility model provide a kind of tread contour of all-steel load-bearing radial tire, good driving can be provided for truck Power, earth-grasping force, wet-sliding resistant performance and lower noise.

The utility model is achieved through the following technical solutions：

A kind of tread contour of all-steel load-bearing radial tire, including center running lug, side pattern block and tire shoulder decorative pattern Block, center running lug setting are entreated in the tread, and the left and right sides sets gradually side pattern block and pattern block on tire shoulder from the inside to the outside, First longitudinal direction groove is set along tire circumferential direction between center running lug and side pattern block, is set in first longitudinal direction groove Set irregular boss；First longitudinal direction groove and second is respectively provided with lateral siping on the furrow bank of groove；Side decorative pattern Second longitudinal direction groove is set along tire circumferential direction between block and pattern block on tire shoulder, it is laterally auxiliary that center running lug is equipped with first Groove, side is helped to be equipped with the second transverse auxiliary decorative patterned groove on pattern blocks, the first transverse auxiliary decorative patterned groove and second laterally assist Groove is respectively to being obliquely installed at left and right sides of tire, between the first adjacent transverse auxiliary decorative patterned groove, the second lateral auxiliary flower Z-shaped siping is respectively set between groove；Lateral shallow slot decorative pattern, the outside of pattern block on tire shoulder are designed on pattern block on tire shoulder Setting heat dissipation groove.

Further, the lateral siping is vertical to groove with first longitudinal direction groove, second respectively.

Further, the lateral siping width is 3-5mm, depth 5-15mm.

Further, the furrow bank of the main groove of the first longitudinal direction and tyre surface normal are in 10-15 ° of angle.

Further, first transverse auxiliary decorative patterned groove, the second transverse auxiliary decorative patterned groove width be 2-3mm.

Further, the depth of the Z-shaped siping is 5-10mm.

Further, the lateral shallow slot decorative pattern width is 2-3mm, depth 2-4mm.

Advantageous effect：The tread contour of all-steel load-bearing radial tire provided by the utility model, passes through pattern block and flower Mutual cooperation between groove provides good driving force, earth-grasping force, wet-sliding resistant performance for truck and lower makes an uproar Sound.Four annular ribs ditches along the circumferential direction extend straight, and are in 0 ° of angle with circumferential line, substantially reduce the rolling of tire Resistance；By the way that irregular boss is arranged in first longitudinal direction groove, groove bottom is partitioned into broken line shape, can effectively be kept away Exempt to carry stone secretly, excellent self-cleaning property is provided；Tread block rigidity can be effectively reduced by transverse auxiliary decorative patterned groove, is increased Texture mapping is grounded flexibility, has good wet-sliding resistant performance；By the way that Z-shaped siping is arranged, tyre surface is substantially reduced in high speed Heat in driving process improves control stability；By in the both sides of first longitudinal direction groove and second longitudinal direction groove Lateral siping is set on furrow bank, keeps pattern block distribution of force uniform；By the way that lateral shallow slot flower is arranged on pattern block on tire shoulder Line improves tyre surface earth-grasping force and wet-skid road surface handling.
