Powertrain
To best meet the needs of our customers around the world, Aisin has a full product lineup of drive units for various types of vehicles, including electric and hybrid vehicles.
Powertrain units
Electric units
eAxle
- This is an EV unit that is a power source for an electric vehicle.
- Combined a motor, an inverter and a transaxle.
- Aisin has contributed to the achievement of top-class electric mileage among electric units by employing new technologies including the optimization of motor magnet arrangement and the use of low-viscosity oil for electric units.
Main applicable vehicles
bZ4X(Toyota), SOLTERRA(SUBARU)
Electric 4WD unit
- A system that drives the rear wheels with a motor developed for front-wheel-drive hybrid vehicles.
- Compact unit with biaxial gear train.
Main applicable vehicles
Prius (Toyota)
1 motor Hybrid Transmission
- Lightweight and highly efficient 1-motor hybrid transmission combining a newly designed FWD 6-speed Automatic Transmission, drive motor, and start/engine disengagement clutch.
- The clutch disengages the engine for EV driving, contributing to lower fuel consumption.
- In combination with the eAxle mounted at the rear of the vehicle, the 1-motor hybrid transmission achieves direct response and torqueful driving.
Main applicable vehicles
Crown CROSSOVER RS (Toyota)
Other transmissions
2 motor Multi Stage Hybrid Transmission
Read more
- Adopting a multistage shift device to a hybrid transmission enables more efficient use of engine and motor energy
- Acceleration performance and high fuel efficiency are achieved by significantly improved system output and transmission efficiency in the entire range
Main applicable vehicles
LC500h,LS500h (LEXUS)
10-Speed Automatic Transmission
Read more
- Rhythmic and smooth shift change is achieved with cross gear steps
- Weight reduction for components, improved hydraulic response, and accuracy achieve excellent responsiveness to the driver’s acceleration
- The LOCK-UP range is significantly expanded by developing a high performance small torque converter, and transmission efficiency is increased which resulted in fuel economy improvement
Main applicable vehicles
LC500,LS500(LEXUS)
CVT
Read more
- Realized outstanding fuel efficiency, 6% better than the current CVT, with direct and powerful driving performance, and top-class gear ratio range by adopting starting gear for CVT for the first time ever in the world
- The narrowed CVT belt and reduced diameter pulley achieves a smooth shift and powerful rhythmic driving performance.
Main applicable vehicles
Corolla Sport,C-HR(Toyota), UX(LEXUS)
Powertrain components
Electric water pump for battery cooling
Read more
The integration of control circuit, motor and pump enables a compact body size that achieves high compatibility to a variety of models. Optimized motor control reduces noise.
Electric water pump for engine cooling
Read more
The electric water pump powered by a motor pumps cooling water to the engine to keep it at an optimal temperature. By cleverly changing the shape and layout of the motor magnet, the pump has become compact and lightweight.
Variable valve timing
Read more
Optimal adjustment of engine intake and exhaust valve shutting timing according to driving conditions contributes to improved output, fuel efficiency and reduced emissions in comparison to conventional types.
Variable intake manifold
Read more
Contributes to improvement of engine output and reduced fuel consumption, by the use of highly airtight variable port length intake valve and a retractable tumble control valve and optimization of intake pulsation and flow velocity.
Continuously variable capacity oil pump
Read more
Incorporates the world's first "Internal Gear Mechanism". With a unique gear tooth form, it continually supplies the minimum oil necessary according to the engine's operating condition, contributing to improvement of fuel economy by reducing the demand on the engine driving the pump.
