Abstract
The invention discloses tire tread patterns for an all-wheel tire of a motor lorry. A plurality of longitudinal serrated grooves are uniformly formed in a tire tread at the position of a tire crown at intervals; transverse grooves which form the included angles of 5 to 15 degrees with the axial direction are uniformly formed in the circumference of the tire tread at the combined position of a tire shoulder and a tire side at intervals; the longitudinal serrated grooves are narrow and deep; the transverse grooves are wide and shallow. According to the tire tread patterns for the all-wheel tire of the motor lorry disclosed by the invention, the structure adopts a serrated longitudinal groove design; the tire can run on a road surface for a long distance; the tire is applicable to running on a muddy road surface because of transverse pattern grooves in the side; the traction performance, the operation performance and the road surface adaptation performance of the tire are good.
Description
Technical field
The present invention relates to tire tread structure, particularly autotruck all position tyre tread contour.
Background technology
Because the performance of existing automobile improves constantly, and the applying of radial-ply tyre, performance requriements to tire further improves, particularly, under running at high speed, the road-holding property of automobile, ground tack, driving safety, saving fuel, resistance to abrasion and low noise are all had higher requirement.Therefore the design of decorative pattern has vital effect to tyre performance.
In prior art, band tire decorative pattern is divided into driving decorative pattern, guiding decorative pattern and trailer decorative pattern conventionally.Tire tread pattern can divide cros-rib tread, circumferential pattern and have in length and breadth decorative pattern concurrently.The common feature of circumferential pattern is that tyre surface is longitudinally continuous, laterally disconnect, thereby tyre surface longitudinal rigidity is large, and lateral stiffness is little, tire anti-slide performance presents horizontal strong and a little less than vertical, the rolling resistance of this rib tire is less, perfect heat-dissipating, but decorative pattern groove easily embeds blinding; Cros-rib tread common feature is that tyre surface is laterally continuous, longitudinally disconnect, thereby tyre surface lateral stiffness is large, and longitudinal rigidity is little, therefore that tire anti-slide performance presents is vertical strong and a little less than horizontal stroke, when automobile turns at a relatively high speed, easily break away, tire drag is also larger, and treadwear is more serious; Have in length and breadth decorative pattern concurrently between circumferential pattern and cros-rib tread, at tyre surface middle part, generally there is zigzag circumferential pattern, on the both sides that approach tire shoulder, be shaped with cros-rib tread, the anti-slide performance in length and breadth of table top is relatively good, therefore the tire of this pattern decorative pattern is adaptable, have wide range of applications, it had both been applicable to different hard pavements, also suitable and in car and lorry.The performances such as the design of decorative pattern is wear-resisting except considering, adherence properties, drainage, also to consider the aesthetic property of tire, and require tire to there is stable startup and deceleration and stopping performance.Research shows, under the same conditions, the resistance to abrasion of cros-rib tread and braking ability are better than the performance of circumferential pattern; But the lateral sliding of cros-rib tread is larger than circumferential pattern, and the oil consumption of cros-rib tread is large, easily falls piece.So common design is that cros-rib tread is combined with by groove with circumferential pattern.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of autotruck all position tyre tread contour, it adopts tortuous longitudinal groove design, tire can long-distance road surface is up be sailed, limit portion cross groove makes tire be adapted at travelling on muddy road surface, and tire traction and operation and road surface conformability are better.
For achieving the above object, the present invention adopts following technical scheme:
Autotruck all position tyre tread contour, its technical scheme is that many longitudinal serration grooves even interval on the tyre surface at crown position is offered, offer with the lateral trench even interval on the tyre surface circumference of tire shoulder and sidewall binding site that is axially 5 °～15 ° of angles, described longitudinal serration groove is narrow and dark, and described lateral trench is wide and shallow.
The lateral trench of tire shoulder and sidewall binding site setting be axially 5 °～15 °, its design has improved driving comfort, increases tyre surface softness.
For guaranteeing the width of groove, in conventional design, longitudinally the ditch edge lengths of the sawtooth ditch of serration groove is unequal.
In preferred version, long ditch edge lengths is short limes marginis 2～3 times.
Three longitudinal serration grooves are preferably set, can have greatly reduced the rolling resistance of tire, can also improve draining and the heat-sinking capability of tire simultaneously, be conducive to reduce noise, also make tire appearance attractive in appearance, generous.
For making tire be adapted at travelling on muddy road surface, the length of tire shoulder position lateral trench is chosen as 2～3 times of position, sidewall lateral trench length.
In conventional design, longitudinally the sawtooth ditch of serration groove is divided into 40～60, lateral trench be divided into 40～60, with guaranteed tire stressed evenly, reduce rolling resistance and the noise that travels.
In conventional design, longitudinally the degree of unsaturation of serration groove and lateral trench is 25%～35%.
Longitudinally trench wall and the angle between tyre surface normal of serration groove and lateral trench are 8 °～25 °, and angle is suitable, and tire has good clean-up performance, is not easy inclusion.
Beneficial effect of the present invention:
Autotruck all position tyre tread contour of the present invention adopts jagged longitudinal groove design, tire can long-distance road surface is up be sailed, and limit portion lateral trench makes tire be adapted at travelling on muddy road surface, and tire traction and operation and road surface conformability are good, tire cost is low, economical and practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the present invention.
Number in the figure is: 1, longitudinal serration groove; 2, lateral trench; 3, long limes marginis; 4, short limes marginis.
The specific embodiment
Below in conjunction with embodiment, the invention will be further described, but the present invention is not limited to described embodiment.
The technical scheme of autotruck all position tyre tread contour of the present invention is:
Article three, longitudinal serration groove 1 even interval on the tyre surface at crown position is offered, longitudinally serration groove 1 is narrow and dark, longitudinally the sawtooth ditch of serration groove 1 is divided into 40～60, and longitudinally the ditch edge lengths of the sawtooth ditch of serration groove 1 is unequal, and long limes marginis 3 is 2～3 times of short limes marginis 4; Offer with the lateral trench 2 even interval on the tyre surface circumference of tire shoulder and sidewall binding site that is axially 5 °～15 ° of angles, the length of tire shoulder position lateral trench 2 is 2～3 times of position, sidewall lateral trench 2 length, lateral trench 2 is wide and shallow, lateral trench 2 be divided into 40～60; Longitudinally the degree of unsaturation of serration groove 1 and lateral trench 2 is 25%～35%; Longitudinally trench wall and the angle between tyre surface normal of serration groove 1 and lateral trench 2 are 8 °～25 °, as shown in Figure 1.
