[0028] To make the purpose, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below in combination with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts fall within the scope of protection of the present application.
[0029] Please refer to Figure 1The high-performance mower tire 100 provided by the application comprises: a tire tread; a first oblique block pattern group 1 and a second oblique block pattern group 2 arranged alternately on the tire tread and at a predetermined oblique angle with respect to the annular center line of the tire tread; a third oblique rib group 3 and a fourth oblique rib group 4 are further arranged on the tire tread between the first oblique block pattern group 1 and the second oblique block pattern group 2 and between the second oblique block pattern group 2 and the first oblique block pattern group 1, respectively; the height of the block pattern of the first oblique block pattern group 1 at the tire shoulder part is higher than that of the second oblique block pattern group 2 at the tire shoulder part; and the sea-land ratio of the tire tread and the first oblique block pattern group 1 and the second oblique block pattern group 2 of the tire tread is between 70% and 80%.
[0030] Specifically, the tire tread (not shown in the figure) is composed of a tire sidewall, a tire shoulder and a tire crown. By arranging the first oblique block pattern group 1 and the second oblique block pattern group 2 on the tire tread, the sea-land ratio of the tire tread and the first oblique block pattern group 1 and the second oblique block pattern group 2 of the tire tread is between 70% and 80%, so as to ensure better maneuverability and grip of the tire.
[0031] Further, by analyzing and adjusting the tire tread by the pressure blanket device, the curvature radius of the tire tread composed of the first oblique block pattern group and the second oblique block pattern group of the tire tread is between 300mm and 600mm, the pressure distribution is more uniform, and local pressure is avoided to be too large to bruise the turf.
[0032] The first oblique block pattern group 1 and the second oblique block pattern group 2 are at a predetermined oblique angle with respect to the annular center line of the tire tread. Specifically, the arrangement of the oblique angle makes the tire have good directivity and ensures sufficient grip performance to prevent skidding. The predetermined oblique angle is between 45° and 60°. In a preferred embodiment provided by the application, the predetermined oblique angle is preferably set to 60°.
[0033] Further, the first oblique block pattern group 1 comprises, in sequence: block pattern one 11 arranged at the tire sidewall of the tire tread, block pattern two 12 arranged at the tire shoulder of the tire tread, block pattern three 13 arranged at the tire crown of the tire tread, block pattern four 14 arranged at the tire crown of the tire tread, block pattern three 13 arranged at the tire crown of the tire tread, block pattern two 12 arranged at the tire shoulder of the tire tread, and block pattern one 11 arranged at the tire sidewall of the tire tread; the second oblique block pattern group 2 comprises, in sequence: block pattern five 21 arranged at the tire sidewall and the tire shoulder of the tire tread, block pattern six 22 arranged at the tire shoulder and the tire crown of the tire tread, block pattern seven 23 arranged at the tire crown of the tire tread, block pattern eight 24 arranged at the tire crown of the tire tread, block pattern seven 23 arranged at the tire crown of the tire tread, block pattern six 22 arranged at the tire shoulder and the tire crown of the tire tread, and block pattern five 21 arranged at the tire sidewall and the tire shoulder of the tire tread; the block patterns in the first oblique block pattern group 1 and the block patterns in the second oblique block pattern group 2 are each provided with a groove 25.
[0034] As can be seen in combination with the drawings, the block pattern four 14 in the first oblique block pattern group 1 is located at the annular center line of the tire tread, and the block pattern three 13, the block pattern two 12, and the block pattern one 11 are sequentially arranged at the tire sidewall on both sides of the tire from the annular center line of the tire tread, and are symmetrically arranged along the central axis of the block pattern four 14. The block shapes of the block pattern one 11, the block pattern two 12, the block pattern three 13, and the block pattern four 14 are different. The block pattern eight 24 in the second oblique block pattern group 2 is located at the annular center line of the tire tread, and the block pattern seven 23, the block pattern six 22, and the block pattern five 21 are sequentially arranged at the tire sidewall on both sides of the tire from the annular center line of the tire tread, and are symmetrically arranged along the central axis of the block pattern eight 24. The block shapes of the block pattern five 21, the block pattern six 22, the block pattern seven 23, and the block pattern eight 24 are different.
[0035] Further, the groove 25 penetrates to one side of the block pattern, which not only increases the tire grip, but also better removes the mud on the block pattern, and increases the tire performance. The depth of the groove 25 is between 2.5 mm and 3.5 mm, and the width is between 1.5 mm and 2.5 mm. The depth of the groove 25 is between 2.5 mm and 3.5 mm, and the width is between 1.5 mm and 2.5 mm. In a preferred embodiment provided in the present application, the depth of the groove 25 is 3 mm, and the width is 2 mm.
[0036] The height of the block pattern of the first oblique block pattern group 1 at the tire shoulder of the tire tread is higher than the height of the block pattern of the second oblique block pattern group 2 at the tire shoulder of the tire tread. Specifically, the high-low design of the tire shoulder of the tire tread can increase the ground adhesion of the tire by 35% to 40% when driving on the grass, and avoid the damage of the fragile turf caused by the tire skid. In addition, this design can also reduce the weight of the tire by about 5%, save costs, and increase the heat dissipation performance of the tire, thereby reducing the risk of tire bulging.
[0037] In a preferred embodiment provided in the present application, the height ratio of the block pattern two 12 of the first oblique block pattern group 1 arranged at the tire shoulder of the tire tread to the block pattern five 21 arranged at the tire side and shoulder of the tire tread and the block pattern six 22 arranged at the tire shoulder and crown of the tire tread of the second oblique block pattern group 2 is set to be between 1:0.2 and 1:0.6. Preferably, the height ratio is set to 1:0.4.
[0038] The tire tread is further provided with a third oblique rib group 3 and a fourth oblique rib group 4 between the first oblique block pattern group 1 and the second oblique block pattern group 2 and between the second oblique block pattern group 2 and the first oblique block pattern group 1, respectively.
[0039] Specifically, in addition to the first oblique block pattern group 1 and the second oblique block pattern group 2 arranged alternately, the third oblique rib group 3 and the fourth oblique rib group 4 are arranged between the alternately arranged first oblique block pattern group 1 and the second oblique block pattern group 2. It can be understood that the oblique angle of the third oblique rib 31 in the third oblique rib group 3 and the fourth oblique rib 41 in the fourth oblique rib group 4 is the same as the oblique angle of the first oblique block pattern group 1 and the second oblique block pattern group 2. Through the design of the oblique rib, not only can the soil between the first oblique block pattern group 1 and the second oblique block pattern group 2 and the second oblique block pattern group 2 and the first oblique block pattern group 1 be divided, but also the small stones can be prevented from being stuck between the first oblique block pattern group 1 and the second oblique block pattern group 2 and the second oblique block pattern group 2 and the first oblique block pattern group 1, thereby increasing the self-cleaning ability of the space between the alternately arranged first oblique block pattern group 1 and the second oblique block pattern group 2. In a preferred embodiment provided in the present application, the height of the oblique rib in the third oblique rib group 3 and the fourth oblique rib group 4 is between 2mm and 3mm.
[0040] Further, the width of the tire tread of the high-performance mower tire 100 in the present application is between 24cm and 30cm. It can be understood that the wide tread not only can disperse the pressure and reduce the damage to the turf, but also can provide the required ground adhesion for driving on the grass, thereby improving the handling performance. The mower can safely drive on the grass without damaging the lawn.
