Schaeffler offers two electric drive axles for the Audi e-tron

     Schaeffler offers two electric drive axles for the Audi e-tron that match the front and rear motors to achieve Audi's signature Quattro electric all-wheel-drive feature. The rear electric drive axle adopts coaxial design to transmit maximum power in limited space; The front electric drive axle has its own electronic parking mechanism, so it has a parallel axle design. The front and rear electric drive axle adopts Schaeffler's representative cascading planetary bank design and lightweight differential to achieve the stringent requirements of high efficiency, high speed, high load and low noise required for electric drive in a compact structure.

     With this bridge signature product portfolio Schaeffler the electric drive axle is the ultimate in space and weight, the diameter and thickness are only 300mm and 150mm, and the weight is less than 15kg, but in such a small space, the Schaeffler electric drive axle achieves up to 400Nm input torque, which can provide more than 3600Nm power output. With such surging power, the Audi e-tron can achieve 100km acceleration of less than 5.7s and a top speed of more than 200km/h.

     In addition, the cascading planetary bank and lightweight differential of the Schaeffler electric drive axle are also modular in design, allowing different arrangements to be realized through free combination. On the Audi e-tron, Schaeffler used parallel axis and coaxial structure according to the different needs of the front and rear axle, but the planetary bank and differential module can be shared, without the need for redesign verification, saving development time and cost. In addition, by adding other functional modules, the function of the electric drive axle can also be expanded, such as the front drive axle of Audi e-tron can realize the parking function by adding a parking module.

     Schaeffler has many years of experience in the development and application of electric drive Bridges. Back in 2011, Schaeffler demonstrated a future-oriented electric drive axle system for pure electric vehicles. On this basis, over the years, Schaeffler has developed a complete family of electric drive Bridges, covering 48V and high voltage systems, which can provide customers with customized products to meet the application needs of light hybrid, strong hybrid, plug-in hybrid and pure electric systems.
