Title: Hiroyuki Ikegami: Innovator in Vehicle Noise Reduction Technologies
Introduction
Hiroyuki Ikegami is a notable inventor based in Wako, Japan. He has made significant contributions to the field of vehicle technology, particularly in reducing road noise through innovative tire and wheel designs. With a total of 2 patents, his work has garnered attention in the automotive industry.
Latest Patents
Ikegami's latest patents include a vehicle tire structure and a wheel for vehicles. The vehicle tire structure features a tubeless pneumatic tire fitted over a wheel, characterized by at least a pair of walls that project radially from the wheel's outer circumferential surface into an annular chamber. These walls are designed to prevent the generation of standing waves or air column resonance inside the tire, contributing to a reduction in road noise. The proximal ends of the walls can be bonded to an annular member surrounding the wheel or pivoted to a similar member, allowing for easy tire replacement. Alternatively, the walls may consist of inflatable bags that can be inflated into upright positions and deflated into flat positions.
The second patent, the wheel for vehicles, aims to reduce road noise without requiring a special tire. This wheel includes a wheel body and a silencing chamber formed around it. The silencing chamber communicates with an air chamber in the tire through a communication port. The phase difference between compressional waves in the air chamber and those returned from the communication port leads to attenuation of road noise.
