Latest Patents

Yamaguchi's latest patents include a lockup device and a fluid type power transmitting device. The primary objective of the lockup device is to improve the fuel efficiency of vehicles. This device features a piston, an output plate, a first coil spring, an inertia member, and a second coil spring. The output plate is coupled to a turbine, allowing it to rotate as an integral unit with the turbine. The first coil spring elastically couples the piston to the output plate in a rotational direction, while the inertia member is designed to rotate relative to the output member. The second coil spring also elastically couples the inertia member to the output plate in a rotational direction.

Another significant patent is the lockup device for a torque converter. This device allows for the use of larger torsion springs and includes a piston and a damper mechanism. The piston constitutes a clutch together with a front cover. The damper mechanism consists of a drive plate, a driven plate, and coil spring assemblies. The drive plate is secured to one axial side surface of the piston, and the coil spring assemblies couple the drive plate and the driven plate in a rotational direction. Cutouts are formed in the drive plate at positions corresponding to the coil spring assemblies, ensuring effective functionality.
