Detailed Description
A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1, a winter tire having staggered blocks includes a tread portion 1, a shoulder portion 2, and a tire pattern disposed on the tread portion and the shoulder portion along a circumferential direction of the tire, the tire pattern includes a center pattern located at a center of the tread and side block patterns 50 located at both sides of the center pattern, the center pattern includes a guide portion 10 located at a center line of the tire and intermediate block patterns 30 located at both sides of the guide portion, a first lateral groove 31 is disposed between any two adjacent intermediate block patterns, any one of the intermediate block patterns and one of the first lateral grooves adjacent thereto constitute a type a pattern section, a second lateral groove 51 is disposed between any two adjacent side block patterns 50, any one of the side block patterns and one of the second lateral grooves adjacent thereto constitute a type B pattern section, a pattern pitch number of the type a pattern section is different from a pattern pitch number of the type B pattern section, and the dislocation value x of the first pattern pitch of the A-type pattern pitch and the first pattern pitch of the B-type pattern pitch in the circumferential direction of the tire is 5.6-8.0 mm.
In the embodiment, the type A pattern sections are two, namely a first pattern pitch PA and a second pattern pitch PB, the number of the first pattern pitches is NPA, and the number of the second pattern pitches is NPB; there are three pattern sections of type B, which are respectively a third pattern pitch PC, a fourth pattern pitch PD and a fifth pattern pitch PE, the number of the third pattern pitches being NPC, the number of the fourth pattern pitches being NPD and the number of the fifth pattern pitches being NPE.
Since the outer circumference of the tire is constant, PA NPA + PB NPB ═ PC ═ NPC + PD ═ NPD + PE ═ NPE ═ the outer circumference of the tire.
When the pattern sections a and B are arranged on the circumferential surface of the tire, the first pattern section P1 of the pattern section a and the first pattern section P2 of the pattern section B have the following relationship: one end of P1 is aligned with one end of P2 in the tire circumferential direction, but due to the difference in length of P1 and P2, the other end of P1 is offset from the other end of P2 in the tire circumferential direction by the offset value x in the tire circumferential direction of the first of the type a and the first of the type B; where P1 is one of first pattern pitch PA or second pattern pitch PB and P2 is any one of third pattern pitch PC, fourth pattern pitch PD or fifth pattern pitch PE.
Because the dislocation exists between the middle block-shaped patterns and the edge block-shaped patterns, and the number of types of pattern pitches possessed by the middle block-shaped patterns is different from the number of types of pattern pitches possessed by the edge block-shaped patterns, the first transverse grooves and the second transverse grooves can be staggered to the greatest extent, in the running process of a vehicle, air in the grooves on the surface of the tire is compressed and moves along the extending direction of the grooves, and the air running at high speed acts with the grooves to generate cavity noise; the first transverse groove and the second transverse groove are staggered to damage the movement of air in the groove on the surface of the tire, slow down the running speed of the tire, and reduce the noise generated when the tire acts with the ground.
To demonstrate the practical effects of the present invention, a tire of specification 245/55R19 was tested.
