Latest Patents

Horikawa's latest patents include an "Automobile power plant mounting structure" and a "Belt-pulley drive mechanism." The automobile power plant mounting structure features a design where the power plant is mounted on both sides in a transverse direction by mounts. Each mount is strategically placed within a triangle defined by specific points related to the power plant's inertial axis and vibration nodes. This innovative approach enhances the stability and performance of the power plant.

The belt-pulley drive mechanism consists of a pulley with multiple circumferential grooves of V-shaped cross-section. It utilizes a belt that is tensioned around the pulley, ensuring a torque-transmitting relationship. The belt is designed with longitudinal ridges that engage with the grooves when tension is applied. Notably, the grooves and ridges are formed along a concave line, creating a clearance when the tension is removed, which is larger at the center than at the edges. This design improves the efficiency and functionality of the drive mechanism.
