Aisin has been granted a patent for a drive device that includes a fluid coupling and a rotary electrical machine. The device is designed to input torque from one side and output it from another side.

1. Don't choose your coupling based on habit or price alone. Because engineers are creatures of habit, choosing a coupling type is often a matter of having selected that same type for a previous ...

Materials — When complicated geometry proves more trouble than it’s worth, the deceptively simple function of transmitting torque can be improved by even small changes in chemical makeup. The core ...
