Drive system with electric machine, two gear stages, clutches
A recently granted patent (Publication Number: US11999226B2) discloses a drive system featuring an electric machine with a unique two-stage transmission design. The system includes a rotor shaft, an intermediate shaft with first and second gearwheels, an oil pump, and two clutches connected to a split output shaft. The arrangement ensures parallel alignment of the rotor shaft, intermediate shaft, and split output shaft, with components fitting within the axial overall rotor shaft length. The design allows for efficient power transfer and compact construction, with the drive gear positioned below the intermediate shaft within the axial length.
Moreover, the patent details methods for operating the drive system, including engaging and disengaging the electric machine through controlled clutch actuation and oil supply regulation. The system incorporates a common oil system for cooling and lubrication, ensuring optimal performance and longevity. The mirror-symmetrical construction of the clutches, along with innovative features like oil barriers and ball ramp parts, further enhance the system's functionality. Overall, the patented drive system offers a sophisticated solution for power transmission in electric machines, combining efficiency, compactness, and ease of operation in a single design.
