Magna electric drives meet all demands for a wide variety of electric vehicle applications. As a full-range system supplier, Transmission Systems supports automakers in designing vehicles and systems equipped with future technologies.
For maximum efficiency, e-drive solutions are needed that meet the challenging requirements. Our powertrains are developed for mid-size up to premium class vehicles as well as for sport cars.
With torque vectoring systems it is possible to actively steer a vehicle by directing torque to the right or left rear wheel.
Driving dynamics rise noticeably due to the fact that the distribution of forces is divided on the propulsive wheels not only when accelerating and in dangerous situations. It also rises when the drive force is purposely forced on the wheel of the outer bend when steering into a bend. With this “purposely applied torque” (Torque Vectoring) the vehicle turns more spontaneous and direct into a bend, and the tracking stability is kept considerably longer. The different, continuously flowing forces between left and right wheel do actively help steering the vehicle.
With this active impact onto the steering there are amazing outcomes possible due to „Torque Vectoring“. A cost-efficient improvement of driving dynamics, of agility and of driving safety is without doubt possible. On top of that, the wearing of brakes is reduced, as the ESP (Electronic Stability Control) has to intervene less.
1 or 2 Speeds
Electric vehicles combine efficient operation with zero local emissions. Furthermore they can offer a new level of fun-to-drive. In many applications, one single gear is an adequate solution. For maximum efficiency of advanced applications, transmissions with additional speeds may be required to add benefit like increased climbing and high-speed capacity. A two speed transmission meets these requirements.
The Benefits of Two Speeds
- 2-speed transmissions deliver more wheel torque at low speeds
- Increased acceleration with smaller traction motor
- Climbing ability significantly improved while maintaining top speed
- E-machine running in high-efficiency regions
- Smaller e-machine for less weight, volume and costs
- Usage of smaller power electronics and battery
- Overall energy reduction of up to 10 -15 % in NEDC (New European Driving Cycle)
Transmission Systems eDRiVE systems are developed for several vehicle platforms and also different vehicle configurations are possible.
