Introduction

Hayato Yamashiro is a notable inventor based in Wako, Japan, recognized for his contributions to motorcycle technology. He holds a total of 5 patents, showcasing his innovative spirit and technical expertise in the field.

Latest Patents

One of his latest inventions is a parking brake apparatus for saddled vehicles. This device is designed to provide a parking brake that is actuated in response to a reverse rotation on a throttle grip, featuring a simplified structure. The apparatus includes a parking brake caliper that restricts the rotation of the rear wheel while the motorcycle is parked. It also incorporates a steering handle for steering the front wheel and a throttle grip that controls the output of the power unit. The control unit actuates the parking brake caliper via a motor when the throttle grip is reversely rotated and the vehicle speed is zero. The system detects the reverse rotation of the throttle grip through information from a throttle position sensor.

Another significant patent is a crank angle detection device for engines. This device aims to achieve downsizing while enhancing the appearance of the engine. It consists of a pulsar ring with multiple detection portions that rotates coaxially with the crank shaft of the engine. A sensor detects the passage state of these detection portions. The pulsar ring is fixed to a crank web of the crank shaft, and a weight for adjusting the inertia balance of the crank shaft is also fixed to the crank web.
