Why is an e-reduction drive required at all in the electric driveline? It increases its efficiency. Engineers have two ways to integrate it into the driveline. They can integrate it into the housing of the electric drive as a component set – consisting of gears and differential. However, a stand-alone solution is also possible. Here, the technology is located in its own housing as an e-reduction drive system. In both cases, the solutions are scalable; they can be displayed in an axially parallel or coaxial configuration.
This only ensures a high power density of the drive once all components have been optimally matched. In addition to efficiency-optimized gearing, the use of low-friction bearings and an overall optimized design with regard to oil splash losses are important for high efficiency of the e-reduction drive. This also includes the selection of the optimal transmission oil. In the case of an e-reduction drive, the components are designed and selected according to the requirements of the individual customer application. ZF relies on tried and tested modular components wherever possible.
