What type of torque converter is the heart of the DIWA transmission's operation?

• A. Counter-rotating
• B. Clockwise
• C. Non-latching
• D. Lock-up

Answer: (A)

The essential feature of the DIWA transmission is a torque converter that uses counter-rotating inertia elements. In this design, two rotors or inertia wheels are arranged to spin in opposite directions. This counter-rotation helps balance angular momentum and smooths the transfer of power from the engine to the transmission, especially as the system shifts through a wide range of operating speeds. The result is smooth acceleration with controlled slip when needed, and a smoother transition toward direct drive as speed increases. This unique torque converter behavior is what enables DIWA to combine the feel of gearing with the efficiency and flexibility of a fluid couple. Other terms describe different aspects of torque converters (direction, whether they latch, or whether a lock-up clutch is used) but they don’t capture the distinctive counter-rotating mechanism that DIWA relies on.
