Title: Makoto Ishizuka: Innovator in Clutch and Differential Technologies
Introduction
Makoto Ishizuka is a prominent inventor based in Tochigi, Japan. He has made significant contributions to the field of mechanical engineering, particularly in the development of clutches and differential apparatuses. With a total of 2 patents, Ishizuka's work showcases his innovative approach to solving complex engineering challenges.
Latest Patents
Ishizuka's latest patents include a wet type friction clutch and an electromagnetic clutch. The wet type friction clutch features a pilot clutch that is strategically placed in the magnetic flux path of an electromagnet. This design allows for the armature to retract upon excitation of the electromagnet, enabling the pilot clutch to engage. The pilot clutch consists of multiple interleaved clutch plates, which are designed with oil guide passageways to create a hydrodynamic pressure effect. This innovation allows for the separation of clutch plates with minimal drag torque.
Additionally, his differential apparatus patent includes a differential casing, helical side gears, and helical pinion gears. The design anticipates changes in the helix angle of the tooth trace due to vehicle driving conditions. By adjusting the tooth depths of the helical pinion gears, Ishizuka ensures uniform contact with the bore, preventing eccentric abrasion and seizure.
