AI Technical Summary
Existing powertrains face challenges in efficiently packaging lubrication systems while minimizing power losses and sedimentation of particles, particularly in the context of electrification trends and differential gear configurations.
The powertrain design incorporates an eccentric configuration for the lubricant compartment, with an inner perimeter profile that allows efficient lubricant flow and reduces the risk of leakage, using separate transmission housings and a differential gear lubricant compartment, and allows for torque transfer through multiple paths.
This design achieves efficient lubricant flow, reduces power losses, and minimizes sedimentation, while enabling compact packaging and cost-effective manufacturing, supporting various vehicle types and power levels.
