Title: Ryousuke Asaoka: Innovator in Continuously Variable Transmission Technology

Introduction

Ryousuke Asaoka is a prominent inventor based in Shizuoka, Japan. He has made significant contributions to the field of continuously variable transmission (CVT) technology, holding a total of 10 patents. His innovative designs have enhanced the performance and efficiency of straddle-type vehicles.

Latest Patents

Asaoka's latest patents include a straddle-type vehicle featuring a continuously variable transmission designed to reduce response delay and hunting due to overshooting. This system is electronically controlled by a control unit, which is connected to an actuator that moves a moving flange of a primary sheave. The control unit manages the actuator's output to facilitate smooth upshifts and downshifts in the transmission. Another notable patent involves a continuously variable transmission that prevents belt fluttering motion when the vehicle starts. This design incorporates a throttle opening degree sensor that detects the throttle's opening degree and sends a signal to a controller. The controller then adjusts the actuator to narrow the groove width of the primary sheave when the vehicle transitions from a standing state.
