Title: **Hirotaka Kanazawa: Innovator in Four-Wheel Steering Technology**
Introduction
Hirotaka Kanazawa, a prominent inventor based in Hiroshima, Japan, has made significant contributions to the automotive industry with a total of 36 patents to his name. His innovative designs, particularly in the field of vehicle steering systems, demonstrate a deep understanding of mechanical engineering and a commitment to improving vehicle performance and safety.
Latest Patents
Among his most recent inventions is a four-wheel steering system designed for vehicles. This system includes a rear-wheel turning mechanism that is intricately connected to the front-wheel turning mechanism via a rear wheel turning angle ratio changing mechanism. This innovative approach allows for mechanical displacement input from the front to influence the rear wheels, enhancing vehicle maneuverability. The control of the rear wheel turning angle is particularly noteworthy, as it initially sets a negative turning angle ratio during the initiation of a turn before transitioning to a positive ratio.
Another significant patent of Kanazawa's is a rear wheel steering device for vehicles. This invention features swingably supported support members at the vehicle body end of suspension arms. These components work in synchronism to operate the left and right rear wheels, allowing them to be steered symmetrically in either toe-in or toe-out directions. The simple construction using link members reduces complexity and potential mechanical backlash, contributing to a more compact design and cost efficiency in production.
