Schaeffler announces new E-Mobility business unit
In its new “E-Mobility” business unit, Schaeffler officials say they are pooling the company’s engineering capabilities, products, and system solutions for hybrid and battery-electric vehicles for the powertrain of the future. “Proceeding from individual products, Schaeffler, from an overall perspective on electrified powertrain topologies, is going to evolve into a company providing technological total system solutions,” Matthias Zink, CEO Automotive at Schaeffler, said.
According to the company, development of Schaeffler’s electric axle provides a modular kit solution for hybrid vehicles and all-electric vehicles. Its range of the E-Axles starts with a single-speed ratio unit featuring a coaxial or parallel-axis design. Due to the planetary-type differential, the transmission is compact and offers assembly space for the electric motor, which is available either as a PSM (permanently excited synchronous motor) or as an ASM (asynchronous motor) with or without power electronics. The base configuration can reportedly be extended by additional functional elements such as the integration of a parking lock. A second gear is required particularly for plug-in hybrid vehicles for which dynamic, all-electric operation up to 120 km/h (74 mph) and high top speed are specified. Due to the two-speed axle developed by Schaeffler, lateral dynamics can be improved via a torque vectoring element. This function is achieved by adding a respective transmission and an electric motor in the range of 7 kW.
In a collaborative partnership with Semikron, Schaeffler is expanding its electronics expertise and, using space-optimized power electronics, has the capability to efficiently convert, control, and integrate electrical energy into the total system.
Schaeffler says it’s leveraging its expertise in engineering on the road to becoming a total system supplier of electric axles and electrified drive systems which are also used in production plug-in hybrid vehicles. Tailored software solutions are designed to ensure loss-free torque transfer or control the interaction between the propulsion units on the total system level. Thus, Schaeffler says it can implement fast control algorithms and customer-specific functions and validate them on in-house test benches.
