Introduction

Yousuke Igarashi, located in Itami, Japan, is a notable inventor recognized for his contributions to the automotive brake technology field. With a patent to his name, Igarashi has made significant strides in improving the performance and safety of braking systems.

Latest Patents

Igarashi's recent patent pertains to an advanced disk brake design, which aims to deliver both low dragging torque and exceptional pedal feel, even in ABS-equipped vehicles that operate with fluid pressure around or exceeding 140 kgf/cm². His innovative disk brake features a piston seal strategically fitted within a groove in the cylinder. This design allows the piston seal to deform when the brake piston is activated by fluid pressure, pressing the pad against the disk. Upon release of the pressure, the seal retracts the piston via its spring-back force. Notably, the width of the chamfer at the seal groove edge is set to a minimum of 1.0 mm, while the hardness of the piston seal is established at 75° IRHD or above.
