Title: Atsushi Ishida: Innovator in Motorcycle Engineering

Introduction

Atsushi Ishida is a prominent inventor based in Kanagawa, Japan, known for his significant contributions to motorcycle engineering. With a total of nine patents to his name, Ishida has developed innovative solutions that enhance the performance and comfort of motorcycles.

Latest Patents

One of Ishida's latest patents is an engine mounting structure for motorcycles. This design includes a plurality of resilient members that connect the engine to the vehicle body frame. The resilient member closest to the rear wheel has a uniform resilient property in both vertical and fore-and-aft directions. In contrast, the remaining members possess a non-uniform resilient property, being hard in the vertical direction while flexible in the fore-and-aft direction. This configuration effectively attenuates the influence of horizontal movement from the rear wheel to the vehicle body frame. Additionally, when a resilient member that is hard in the vertical direction is utilized, the behavior of the rear wheel, such as vertical swinging motion or lateral turn, can be promptly transferred to the vehicle body frame. Consequently, this innovation significantly improves the drivability of motorcycles during high-speed driving.

Another notable patent by Ishida involves an engine mounting structure in a scooter-type motorcycle. This design features a rear fork that supports the motorcycle's rear wheel. The front portion of the rear fork is attached to the engine's crankcase in a vertically swingable manner. The engine is mounted to the body frame through elastic members, which enhances ride comfort by reducing vibrations transmitted from the rear wheel to the rider.
