Denso in Southfield, along with BluE Nexus Corp. and AISIN Corp., have announced the development of a new 1-motor hybrid transmission used for Toyota’s new Crown Crossover RS, which is expected to release in fall of 2022.
The 1-motor hybrid transmission integrates the newly designed Direct Shift-6AT with a driving motor and an inverter. It is characterized by high acceleration performance and contributes to fuel efficiency.
In addition to the eAxle mounted at the rear of the vehicle, the 1-motor hybrid transmission complements the Crown’s 2.4-liter turbo engine.
Toyota states the Crown achieves both direct response and smoothness, contributing to the high-quality ride inside the vehicle by combining the latest technologies with automatic transmission gear shift technology.
Similarly, there have been improvements with the ability to mount the transmission in the vehicle through downsizing technology and the electromechanical integration structure. The driving motor has been significantly downsized by reducing the stator shaft length in which energy flows through, the coil expansion, as well as cooling the coil and optimizing the magnet layout.
The large-diameter flat motor has enabled the placement of two clutches inside the motor rotor, making it possible to restrain the increase in the overall length of the product. This is further improved by using the electromechanical integration structure, in which an inverter is mounted right above the transmission.
