Description

具抗偏磨耗的輪胎 Tires with anti-uniform wear

本發明是關於一種輪胎，尤其是有關於一種具抗偏磨耗的輪胎。。 The present invention relates to a tire, in particular to a tire with anti-uniform wear. .

摩托車用輪胎，在乾燥路面上，從直行到轉彎時的傾斜行駛要求有穩定性，特別是傾斜過程中要求均勻的過渡特性和適度的舒適性。而當地潮濕時，輪胎的濕地抓地性，就顯得非常重要。其中，為了抑制水漂現象，沿輪胎周向的溝非常有效，隨著相對于輪胎周向的角度增大。另一方面，在乾燥路面上，在轉彎時需要大的橫向力，但周向溝產生的橫向力(側抗力、外傾推力)很小，因此無法獲得充分的轉彎力。 Motorcycle tires, on dry roads, require stability from straight driving to turning when inclined, especially uniform transition characteristics and moderate comfort during inclination. When the local area is wet, the wet grip of the tires is very important. Among them, in order to suppress the water drift phenomenon, the grooves along the tire circumferential direction are very effective, and the angle with respect to the tire circumferential direction increases. On the other hand, on a dry road surface, a large lateral force is required when turning, but the lateral force (yellow resistance force, camber thrust force) generated by the circumferential groove is small, and a sufficient turning force cannot be obtained.

在前案中國發明專利公告號CN103863017B「摩托車用輪胎」，其揭露係胎面表面具有中央傾斜主溝，該中央傾斜主溝從輪胎赤道面附近的內端到比直立時的接地寬度區域靠輪胎軸向外側的外端以角度α朝向輪胎周向側傾斜地延伸，並且交替地在輪胎赤道面的兩側被設置。在直立時的接地寬度區域內，周向上相鄰的中央傾斜主溝之間的間隔在直立時的接地長度的0.5倍以下。在直立時的接地寬度區域內，輪胎軸向上相鄰的中央傾斜主溝在輪胎軸向上局部重疊。中央傾斜主溝在直立時的接地寬度區域內的周向的溝長度小於上述接地長度。 In the previous case, Chinese Invention Patent Publication No. CN103863017B "Tyres for Motorcycles", it is disclosed that the tread surface has a central inclined main groove, and the central inclined main groove extends from the inner end near the tire equatorial plane to the ground contact width area when standing upright. The outer end of the tire axially outer side extends obliquely toward the tire circumferential direction side at an angle α, and is alternately provided on both sides of the tire equatorial plane. In the ground contact width region when standing, the interval between adjacent central inclined main grooves in the circumferential direction is 0.5 times or less the ground contact length when standing. In the contact width region when standing, the adjacent central inclined main grooves in the tire axial direction partially overlap in the tire axial direction. The circumferential groove length of the central inclined main groove in the ground contact width region when standing is smaller than the above ground contact length.

上述專利案雖然能提升乾地舒適性及過彎抓地力，但在周向上相鄰的中央傾斜主溝之間的間隔在直立時的接地長度的0.5倍以下，及在直立時的 接地寬度區域內，輪胎軸向上相鄰的中央傾斜主溝在輪胎軸向上局部重疊等結構特徵，在實車使用中易有磨耗異常情況產生。 Although the above-mentioned patent case can improve dry comfort and cornering grip, the interval between adjacent central inclined main grooves in the circumferential direction is less than 0.5 times the ground contact length when standing, and the In the area of the ground contact width, the adjacent central inclined main grooves in the tire axial direction partially overlap in the tire axial direction and other structural features, which are prone to abnormal wear in the use of real vehicles.

由表一為其中的該大溝槽33的第一夾角θ1介於28度至45度之間，透過有限元素分析(FEA)模擬實驗可得知雙邊壓力分佈GAP值平均為：0.0139，由表二為另外的該大溝槽33的第一夾角θ1為46度，透過有限元素分析(FEA)模擬實驗可得知雙邊壓力分佈GAP值平均為：0.0324，當雙邊壓力分佈GAP值越大時，越容易產生偏磨耗情形，經由有限元素分析(FEA)模擬實驗可得知，該大溝槽33的第一夾角θ1介於28度至45度之間較不易產生偏磨耗情形，而當該大溝槽33的第一夾角θ1大於45度時，容易產生偏磨耗情形。 From Table 1, the first angle θ1 of the large groove 33 is between 28 degrees and 45 degrees. Through the finite element analysis (FEA) simulation experiment, it can be known that the average GAP value of the bilateral pressure distribution is: 0.0139. The second is that the first angle θ1 of the other large groove 33 is 46 degrees. Through the finite element analysis (FEA) simulation experiment, it can be known that the average GAP value of the bilateral pressure distribution is 0.0324. When the bilateral pressure distribution GAP value is larger, the The easier it is to produce partial wear, it can be known from the finite element analysis (FEA) simulation experiment that the first angle θ1 of the large groove 33 is between 28 degrees and 45 degrees, and it is less likely to produce partial wear. When the first included angle θ 1 of the grooves 33 is greater than 45 degrees, uneven wear is likely to occur.
