Title: Hidetoshi Yokota: Innovator in Tire Technology
Introduction
Hidetoshi Yokota is a prominent inventor based in Kawasaki, Japan, known for his significant contributions to tire technology. With a total of six patents to his name, Yokota has focused on innovations that enhance tire performance and efficiency.
Latest Patents
One of Yokota's latest patents is for a pneumatic tire featuring a multiple modulus body cord designed to reduce rolling resistance. This innovative tire includes a body with several main body cords, where the modulus of the cords is greater in the lower section than in the upper section. This design effectively decreases the rolling resistance of the tire. The increased modulus in the lower section is achieved by incorporating intermediate body cords between the main body cords. In another embodiment, the modulus is enhanced by altering the material and/or size of the cords in the lower section.
Another notable patent by Yokota is for a pneumatic tire with a multiple element bead assembly. This invention addresses tire flat spotting by providing a bead assembly that includes bead filler elements positioned outside the body cords. This configuration allows the turn-up portion of the ply of body cords to be placed directly against the main portion of the ply above the bead core. The resulting carcass structure increases the stiffness of the lower sidewall and minimizes the flat spotting experienced by the tire. In one embodiment, a reinforcing ply is wrapped around the bead filler elements to further enhance the stiffness of the lower sidewall.
