Single-speed eDRiVE transmission 1eDT330

Single-Speed eDRiVE for Performance Applications

The electric single-speed transmission 1eDT330 has been developed for full electric sport cars up to premium class vehicles, whereby different vehicle configurations are possible (front-, rear- and all-wheel drive). In addition to the electric vehicle applications the 1eDT330 is perfectly suited as drive unit for hybrid vehicles.

The transmission with one constant ratio has a very compact design. The electric motors and the transmission are modular components. The transmission is a double gear type with an electric motor for each wheel side. Differential function is performed through the regulation of the electric motors, thus enabling single wheel torque distribution (torque vectoring). Furthermore, and depending on the application, the transmission provides a mechanically operated park lock (cable pull). By its compact design, it can easily be integrated into diverse vehicle platforms.

The 1eDT330 is designed to use two electric motors with a maximum power of up to 2x150 kW. The motors are water-cooled. The maximum driving torque of 3300 Nm on the output side offers boost mode and recuperation of energy in addition to purely electric driving
