Abstract
A drive assembly for a motor vehicle generally consisting of a first planetary gear set including a rim gear drivingly connected to an input shaft, a planetary gear carrier mounted on a first output shaft and a sun gear mounted on a second output shaft; a second planetary gear set including a planetary gear carrier mounted on the second output shaft and a planetary gear set drivingly connected to the planetary gear carrier of the first planetary gear set; and a selectively engergizabe electric motor including a rotor mounted on the sun gear of the second planetary gear set.
Claims8
A drive assembly for a motor vehicle, comprising:
- a first planetary gear set including a rim gear drivingly connected to an input shaft, a planetary gear carrier mounted on a first output shaft and a sun gear mounted on a second output shaft;
- a second planetary gear set including a planetary gear carrier mounted on said second output shaft and a planetary gear set drivingly connected to an internal gear of said planetary gear carrier of said first planetary gear set;
- and
- a selectively energizeable electric motor including a rotor mounted on a sun gear of said second planetary gear set.
A drive assembly comprising:
- a beveled gear differential including a housing rotatable about an axis and drivingly connectable to an input shaft, and a pair of output shafts disposed coaxially with respect to said differential housing;
- a countershaft disposed parallel to said axis and drivingly connected to said output shafts through gear connections;
- and
- a selectively energizeable electric motor having a rotor coaxially disposed on a gear portion mounted on said countershaft for rotation therewith and a stator coaxially disposed on a gear portion meshing with a gear mounted on one of said output shafts.
A drive assembly for a motor vehicle comprising:
- a beveled gear differential including a housing rotatable about an axis and drivingly connectable to an input shaft, and a pair of output shafts disposed coaxially with respect to said differential housing;
- and
- a pair of planetary gear sets,
- wherein each of said planetary gear sets includes a sun gear disposed coaxially relative to one of said output shafts and connected to a rotor of an electric motor, a ring gear disposed coaxially relative to said one output shaft and connected and rotatable with one of said differential housing and said one output shaft, and a planetary gear carrier disposed coaxially relative to said one output shaft and connected to and rotatable with the other of said differential housing and said one output shaft.
