Technology and Products Major product information : Hybrid Transmission
Aiming to create an environmentally friendly society.
In an era that seeks to establish harmony between nature and society, we endeavored early to develop
environmentally friendly products, and in 2004, we were the first auto parts manufacturer to develop a hybrid system.
We conduct integrated operations from system development to production of motors, and are energetically tackling the building of eco-friendly cars.
RWD Multi Stage
Achieved excellent acceleration performance that renews the hybrid car driving experience and improved fuel economy.
Aiming to create the ultimate transmission that achieves amazing acceleration performance and environmental friendliness on an unprecedented scale, Aisin AW successfully developed a high torque capacity RWD 2-motor hybrid transmission in 2006 and the world's first RWD Multi Stage Hybrid Transmission,which reinvigorated the hybrid car driving experience, in 2017.
- ・Adopting a multistage transmission mechanism to a hybrid transmission enables more efficient use of engine and motor energy.
- ・Acceleration performance and high fuel economy are achieved by significantly improved system output and transmission efficiency in the entire range.
Applicable vehicle LC500h（LEXUS）
Incorporating a transmission mechanism into the current hybrid system achieves greater driving response
Adopting a multistage transmission mechanism to a hybrid transmission enables more efficient use of engine and motor energy.
A widely spread gear ratio improves both fuel economy and acceleration performance
Acceleration performance and high fuel economy are achieved by significantly improved system output and transmission efficiency in the entire range.
Fuel Economy Improvement
Small Torque Capacity FWD 2-Motor Hybrid Transmission
The hybrid transmission has been significantly downsized while achieving ever higher fuel efficiency, to further improve products
In 2004, we started production of compact hybrid transmissions characterized by ultra-high fuel efficiency by taking full advantage of our expertise in manufacturing ATs. In 2015, we started production of the AWFHT15, the latest model with a FWD 2-motor hybrid transmission.
Size and weight reduced compared to the conventional product, by arranging dual motor shafts, increasing engine speed, etc.
- ・Smaller in size and lighter in weight compared to the previous product thanks to the multi-axis positioning of the motor and a higher rotation speed.
- ・Loss was reduced by approximately 20% compared to the previous product by changing to a parallel axis reduction gear (from a planetary gear) and applying a new structure to the motor.
Applicable vehicle PRIUS（TOYOTA）
Downsizing and high fuel efficiency have been achieved by drastically changing the layout
Reduced total length (by 12%) and weight has been achieved compared with the conventional product by increasing
the motor speed and employing the dual shaft layout (i.e. having two separate motor shafts).
The reduction gear foramplifying the motor torque has been changed from the planetary gear to the parallel shaft gear mechanism.
A motor with a new structure has also been introduced.
As a result, loss has been reduced by about 20% from the conventional product.
This product helps effectively utilize space and increase fuel efficiency.
