Dual motor multi driving mode e-Axle (DMM Axle) 2024 JSAE Automotive Engineering Exposition Univance Corporation
-Torque vectoring e-axle with independent left and right reduction mechanism combined with a motor of Yamaha Motor. -Symmetrical drive shaft length, differential efficiency, and mass can be achieved by placing the reduction gear inside the center. -The inverter is placed on the side, resulting in a flat, low center of gravity. -Expected to be used in supersport cars and trucks.
-Symmetrical gearbox with bevel gear and vertical motor layout for improved weight balance and space savings. -The motor is installed in the longitudinal direction of the vehicle, and the gearbox axis is perpendicular to the motor axis, which makes the unit's center of gravity the center of the vehicle, contributing to improved vehicle dynamics.

Dual Motor Multi Driving Mode e-Axle(DMM Axle) MarkLines Online Expo 2021 Univance Corporation
The DMM Axle is an innovative e-Axle that incorporates two motors and a two-stage gearbox, and automatically switches between four power running modes and two regenerative modes to achieve both low power consumption and high dynamic performance. The compact and flat structure allows for a low center of gravity and greater flexibility in interior and exterior design.
