Title: Yutaca Hagiwara: Innovator in Disc Brake Technology
Introduction
Yutaca Hagiwara is a notable inventor based in Fujisawa, Japan. He has made significant contributions to the field of automotive technology, particularly in the design and functionality of disc brakes. With a total of 3 patents to his name, Hagiwara's innovations have enhanced vehicle safety and performance.
Latest Patents
Hagiwara's latest patents include a disc brake design that features oppositely swingable cylinders and calipers. This innovative design allows for a single brake cylinder to directly load an inner pad against a disc, while a yoke indirectly loads an outer pad. Both components swing about their respective pivot axes, which are substantially parallel to the disc. This mechanism ensures that when the brake is applied, the cylinder and yoke swing in opposite directions, effectively loading the trailing portion of each pad with greater force to reduce brake noise.
Another significant patent is a warning device for indicating wear of friction pads in disc brakes. This device consists of a sensor made from a springy material, which is mounted in the space between the friction disc and pad assembly and the yoke. The sensor has a tongue portion that rubs against the rotating disc when the friction pad wears down to a predetermined thickness. This action emits an audible warning sound, alerting the driver to take appropriate action.
