Embodiment Construction

[0017] The section of traditional wide-base radial tire is as follows: figure 2 As shown, the tread arc is given by l 1 , l 2 and l 3 Composed of three arcs. For ordinary radial tires, this method is simple and easy, and the overall performance of the tire is good. However, for wide-base radial tires, due to the wide tread, it is difficult to control the deformation of the crown when the tire touches the ground. The three-segment arc wide-base radial Tires often show vase-shaped and hourglass-shaped footprints in the ground, such as Figure 4 , 5 shown. This shape is a macroscopic manifestation of uneven ground pressure distribution. Such tires are often scrapped early due to local excessive wear during use, which greatly reduces the service life of the tire. Similarly, the uneven distribution of ground pressure will also affect the grip performance of the tire.

[0018] Therefore, how to control the deformation of the tire crown during the ground contact process is ve...

Abstract

The invention discloses a wide base radial tire tread arc tire, and relates to a novel structure form of radial tire tread arc. The tread with a tread width of L is successively divided into four arc sections including a first section tread, a second section tread, a third section tread and a fourth section tread. The four arc sections are arranged symmetrically to the midpoint of the tread. Adjacent arcs are tangent. The arc lengths of the first section tread, the second section tread, the third section tread and the fourth section tread are L1, L2, L3 and L4, wherein L1 = L4, and L2 = L3. The length of L1 and L4 are respectively of 10%-15% of the tire tread width L. Three arcs of the conventional tread are changed into four arcs. The highest point of the tread arc is changed into two, which are symmetrically distributed on both sides of the longitudinal central plane of the tire. The structure effectively controls the deformation of a tire crown, improves the ground pressure distribution of the tire, and improves grounding performance of the wide base radial tire.

Description

technical field [0001] The invention relates to a wide-base radial tread arc tire. Specifically, the deformation of the tire crown is controlled by a new structural form of the radial tire tread arc, thereby improving the grounding performance of the automobile tire, which belongs to the field of automobile parts. Background technique [0002] The role of the car and the ground is achieved through tires. The performance of tires has an important impact on the ride comfort, handling and safety of the vehicle, and determines the characteristics of the load transfer between the vehicle and the ground. The ground contact mark is the mark formed when the tire is in contact with the ground after the load is applied, and it can reflect the distribution of the tire contact pressure. The ground pressure distribution has an important influence on the handling stability of the vehicle, and it determines the wear of the tire tread, which has an important influence on the service life o...
