Title: The Innovations of Yoshihisa Ieda
Introduction
Yoshihisa Ieda is a prominent inventor based in Saitama, Japan. He has made significant contributions to the field of vehicle technology, holding a total of 18 patents. His work primarily focuses on enhancing the functionality and operability of saddle-ride-type vehicles.
Latest Patents
One of his latest innovations is the "Shift Control Device of Saddle-Ride-Type Vehicle." This device features a lost motion mechanism and a locking mechanism that work together to improve the shifting process in vehicles. The lost motion mechanism is strategically placed between a shift spindle and a shift drum, allowing for relative rotation while accumulating force. The locking mechanism restricts the rotation of both the shifter-side and drum-side rotary members, ensuring precise control.
Another notable patent is the "Gear Shift Device," which changes speed by transmitting the rotation of a shift spindle through an intermittent feed mechanism and a lost motion mechanism. This device includes an upstream rotation holding mechanism that maintains the required rotational position of the upstream rotating member. This innovation allows for smooth gear shifts without the need for continuous operation, thereby enhancing user experience.
