AI Technical Summary
Existing coolant supply systems for electrically operated vehicle axes have a high total construction height due to the stator housing and coolant fuselage geometry, which hinders package optimization and is difficult to reduce without compromising coolant functionality.
The coolant fuselage is positioned with a transverse offset from the rotor axle vertical level, overlapping with the stator housing height to reduce the total construction height, and is divided into two crush channels on either side of the rotor axle to manage coolant flow during different driving conditions.
This configuration reduces the total construction height of the electrical machine while maintaining coolant functionality, ensuring operational safety during cornering, uphill, and downhill driving by effectively managing coolant flow and return.
