Transmissions for EV

The optimal blend of using planetary gears and normal gear stages, enables a new family of compact two speed transmissions for electric vehicles. Usually, electric vehicles have to install large electric motors that must combine good vehicle launch with an acceptable top speed. The vehicle’s overall performance, particularly its launching capabilities and top speed are improved tremendously when installing a 2-gear transmission. Next to this, it also realizes an electric driving range improvement of up to 10% dependent on circumstances and vehicle characteristics. The gearshift between the 2 gears should not be felt by the driver as he assumes continuous drive power by virtue of the electric drive. For this purpose, DTI is developing a number of powershift twinspeed gearboxes, that have applications for:

• low to high speed electric machines
• light vehicles up to heavy duty trucks and buses and
• in-wheel or differential based drives.

Next to this also extensions to 3speed and even 4speed powershift transmissions especially for parallel PHEV structures are available. Download the PHEV leaflet >>
