Abstract:
1. An electric drive module for motor vehicles having first and second wheels, comprising: an electric motor; an input member driven by said electric motor; an output member; a two-speed module operable for selectively establishing first and second speed ratio drive connections between said input member and said output member, said two-speed module including a gearset, a first clutch, a second clutch, and a clutch actuator, said gearset including a first component driven by said input member, a second component driving said output member, and a third component, said first clutch being operable in a released mode to permit relative rotation between said first component and said second and third components and in an engaged mode to restrict relative rotation between said first component and said second and third components, said second clutch being operable in a released mode to permit rotation of said third component and in an engaged mode to restrict rotation of said third component, said clutch actuator being operable in a first mode to establish said first speed ratio drive connection by shifting said first clutch into its engaged mode and said second clutch into its released mode, and said clutch actuator being operable in a second mode to establish said second speed ratio drive connection by shifting said first clutch into its released mode and said second clutch into its engaged mode; and a differential assembly having a differential input driven by said output member, a first differential output drivingly connected to the first wheel, and a second differential output drivingly connected to the second wheel.
