Detailed Description

The utility model discloses be applied to the drive wheel of robot truckle and follow the driving wheel, be applicable to various outdoor adverse circumstances, walk on different places (like cement ground, silt ground, meadow etc.), provide better ground power, comfort level of grabbing, lower noise.

As shown in fig. 1 and 2, the utility model discloses cross-country composite pattern truckle tire, including tire body 1 and tire pattern portion 2, tire pattern portion 2 includes transverse groove 22, vertical groove 21, and vertical groove 21 sets up along tire body 1 circumference, and vertical groove 21 is coaxial with tire body 1, and transverse groove 22 is parallel to each other along the horizontal setting of tire body 1, transverse groove 22 and the center pin of tire body 1.

The longitudinal grooves 21 include a first longitudinal groove 211 and a second longitudinal groove 212, and the first longitudinal groove 211 is provided at a central position of the tire body 1, that is, on a longitudinal center line of the tire body 1. The second longitudinal grooves 212 are parallel to the first longitudinal grooves 211 and symmetrically located at both sides of the first longitudinal grooves 211. The first longitudinal groove 211 and the second longitudinal groove 212 are closed loops provided along the circumferential direction of the tire body 1.

The first longitudinal groove 211 has a semicircular cross section. The semicircular first longitudinal groove 211 can reduce friction force, so that energy consumption of the tire is reduced in the walking process, and the walking is smoother and more stable. The semicircular section also increases the contact area of the tread, so that the straight walking is more straight.

The second longitudinal grooves 212 have an inverted trapezoidal cross section, and the first transverse grooves 221 have an inverted trapezoidal cross section. The heat energy generated by the friction between the tread and the ground can be cooled more quickly, and the service life of the tire is prolonged. The air of tread and ground can be effectively discharged to the trapezoidal cross section of falling, is favorable to the exhaust more. In rainy days, the rainwater flows along the second longitudinal groove 212 in the running process of the tire, so that the splash-proof effect is achieved.

The lateral grooves 22 include a first lateral groove 221 and a second lateral groove 222, the first lateral groove 221 is disposed between the two second longitudinal grooves 212 and communicates with each other, and the second lateral groove 222 is disposed outside the second longitudinal grooves 212 and communicates with each other. Is more beneficial to water drainage and air exhaust. The second transverse grooves 222 assume a wavy irregular shape as viewed on the tread. Tests show that the wavy irregular shape is the best in tire grip and the best in wear resistance.

The tire pattern 2 further includes a small groove 23, the small groove 23 communicating the second transverse groove 222 with the tire outer rim. Is beneficial to water drainage and air exhaust and reduces energy consumption.

The second longitudinal groove 212 is deeper than the second transverse groove 222. The small groove 23 is shallower in depth than the second lateral groove 222, and the small groove 23 is shallower in depth than the first longitudinal groove 211. The small grooves 23 are mainly arranged for reducing energy consumption, draining water and exhausting air. The small groove 23 is shallower than the first longitudinal groove 211, which is advantageous for preventing water in the second longitudinal groove 212 from splashing to both sides of the tire.

The first lateral grooves 221 are spaced 10 degrees apart. That is, the central angle between two adjacent first transverse grooves 221 is 10 degrees. The first transverse grooves 221 are perpendicular to the first longitudinal grooves 211. Experiments prove that the heat energy generated by the friction between the tire tread and the ground can be cooled more quickly at an interval of 10 degrees, and the service life of the tire is prolonged.

The depth of the second transverse grooves 222 is 5mm to 8mm. The off-road performance can be improved. In the off-road situation, the terrain is complex, such as mud, cement, stone and the like, and tests prove that when the depth of the second transverse groove 222 is 5mm-8mm, the stones and the like can be prevented from being clamped on the tread.

The utility model discloses a but not limited to following specification: phi 250X50\ phi 300X50\ phi 250X80\ phi 300X80\ phi 320X85\ phi 400X100. The front number is the tire diameter, and the rear number is the width of the tire body 1 (tread).
