Patent number: 11571932Abstract: The disclosed technology generally relates to a tire and more particularly to a non-pneumatic tire. The non-pneumatic tire that has maneuverability similar to a pneumatic tire even without using air pressure, and can support the load of a vehicle and can guide performance-oriented tire deformation behavior by using a meta structure. In an aspect, a non-pneumatic tire includes a tread that comes in contact with the ground, a rim that is connected with an axle, and a spoke unit that serves as a structural support between the rim and the tread, in which the spoke unit is formed in a meta structure in which unit structures are repeated.Type: GrantFiled: November 4, 2019Date of Patent: February 7, 2023Assignees: Hankook Tire & Technology Co., Ltd., Korea Advanced Institute of Science and TechnologyInventors: Sung Hee Youn, Seok Ju Choi, Myong Joong Lee, Jeong Mu Heo, Daniel Saakes, Tek Jin Nam, Seung Ryeol Kim, Se Yeong Kim, Yea Kyung Row, Oo Sung Son, Dong Hyeok Yun, Kwang Eun Park, Gi Tae Koo, Jeong Yeon Lee

Patent number: 11298979Abstract: The disclosed technology generally relates to a tire, and more particularly to a non-pneumatic tire that has handling performance similar to a pneumatic tire, supports the load of a vehicle and improves riding comfort by employing a parametric structure. In one aspect, a non-pneumatic tire includes a tread that comes in contact with the ground, a rim that is connected with an axle, and a spoke unit that functions as a structural support between the rim and the tread, in which the spoke unit is formed by circularly arranging spokes. The spokes have a single closed-loop longitudinal cross-section circumscribed to the rim and around the center of the tire.Type: GrantFiled: November 4, 2019Date of Patent: April 12, 2022Assignees: Hankook Tire & Technology Co., Ltd., Korea Advanced Institute of Science and TechnologyInventors: Sung Hee Youn, Seok Ju Choi, Myong Joong Lee, Jeong Mu Heo, Daniel Saakes, Tek Jin Nam, Seung Ryeol Kim, Se Yeong Kim, Yea Kyung Row, Oo Sung Son, Dong Hyeok Yun, Kwang Eun Park, Gi Tae Koo, Jeong Yeon Lee

Patent number: 9931892Abstract: A tread kerf of a snow tire is capable of securing the performance of the tire on a dry road, a wet road, a snowy road, and an icy road, maintaining uniform rigidity of the block, and improving wear resistance. The tread kerf is formed in the outer surface of a tread block of the snow tire in a depth direction of the block in a shape of a polygonal wave extending along the outer surface of the block, wherein the entrance distance of the polygonal wave is less than the bottom distance of the polygonal wave such that side surfaces between the entrance and the bottom of the polygonal wave are formed as inclined surfaces, the distance between which decreases toward the entrance. The polygonal wave is moved in an advancing direction of the polygonal wave while being twisted in the depth direction of the block.Type: GrantFiled: August 17, 2015Date of Patent: April 3, 2018Assignee: HANKOOK TIRE CO., LTD.Inventors: Min Su Jang, Sang Tak Joo, Sung Hee Youn

Patent number: 9764600Abstract: A pneumatic tire for a vehicle is herein disclosed. The pneumatic tire includes a tread, side walls, and beads. A plurality of tread blocks and grooves are formed in the tread. Kerfs are formed in the tread blocks. Each kerf face of each of the kerfs includes a flange portion, a plurality of concave kerf portions, and a plurality of convex kerf portions. The flange portion is formed in the outermost portion of the tread. The concave kerf and convex kerf portions are connected to the flange portion, and are alternately formed in depth and lengthwise directions of the kerf. The concave kerf portions correspond to opposite convex kerf portions. The convex kerf portions correspond to opposite concave kerf portions. The concave and convex kerf portions are configured such that the protrusion directions of the concave and convex kerf portions are opposite to each other.Type: GrantFiled: January 13, 2015Date of Patent: September 19, 2017Assignee: HANKOOK TIRE CO., LTD.Inventors: Jin Seop Kim, Sang Tak Joo, Sung Hee Youn, Su Jin Son, Myoung Joong Lee, Sang Moo Lee, Mu Yeong Kim

Patent number: 9561690Abstract: The present invention provides a kerf structure for a snow tire, including unit structures on each of which spiral-shaped protrusions are continuously formed to be spaced a predetermined distance apart on the outer circumferential surface of a semi-cylindrical shaped column, wherein the continuously formed unit structures are arranged by alternating convex and concave portions in a zigzag formation, which is capable of optimizing the rigidity which can maintain gripping force as an original function of a kerf while ensuring a friction force generated from small blocks of a tread portion partitioned with kerfs by collapsing a block at an optimum level and further ensuring the kerf function on snow even in the last stages of tread wear by lowering the rigidity of the blocks of the tread portion.Type: GrantFiled: October 13, 2014Date of Patent: February 7, 2017Assignee: Hankook Tire Co., Ltd.Inventors: Sang Tak Joo, Sung Hee Youn, Su Jin Son, Myoung Joong Lee, Sang Moo Lee, Mu Yeong Kim

Patent number: 9561689Abstract: The present invention relates to a kerf structure for a snow tire, including a wave-shaped straight portion and an expansion portion formed expanding from the straight portion, wherein the expansion portion includes unit structures, on each of which central semi-sphere holes and polygonal forms around the semi-sphere holes form protrusions in opposite directions are formed continuously. According to the present invention, the kerf structure for a snow tire provides a symmetric shape, thereby securing uniform block rigidity regardless of the direction of the kerf, and the interlocking effect can be maximized through the combination of the protrusion shape of the polygonal shape and the embossing of the semi-sphere hole.Type: GrantFiled: October 13, 2014Date of Patent: February 7, 2017Assignee: Hankook Tire Co., Ltd.Inventors: Sang Tak Joo, Sung Hee Youn, Su Jin Son, Myoung Joong Lee, Sang Moo Lee, Mu Yeong Kim
