Patent Images
1. A hybrid vehicle having front and rear wheels, comprising:
- a front drive axle assembly connected with the front wheels;
a rear drive axle assembly connected with the rear wheels;
an engine;
a transmission having;
a motor/generator;
a stationary member;
a planetary gear set having a ring gear member, a sun gear member, and a carrier member, at least one of the members of the planetary gear set being connected to one of said axle assemblies; and
a plurality of selectively engagable torque-transmitting mechanisms;
wherein said engine and said motor/generator are separately selectively connectable to one of said drive axle assemblies by engagement of different ones of said torque-transmitting mechanisms to transfer torque to said one of said drive axle assemblies; and
wherein at least one of said engine and said motor/generator is selectively connectable to the other of said drive axle assemblies by engagement of another one of said torque-transmitting mechanisms to transfer torque to the other of said drive axle assemblies.

Abstract
A hybrid vehicle is provided with an engine, as well as a transmission having a motor/generator, a stationary member, and a planetary gear set. The engine and the motor/generator are separately selectively connectable to one of the drive axle assemblies by engagement of different ones of the torque-transmitting mechanism to transfer torque to that drive axle assembly. One or both of the engine and the motor/generator is also selectively connectable to the other drive axle assembly by engagement of another one of the torque-transmitting mechanisms to transfer torque to the other of drive axle assembly.

10. A hybrid powertrain for a vehicle having a front axle assembly connected with front wheels and a rear axle assembly connected with rear wheels comprising:
-
an engine; a transmission having; a planetary gear set with a sun gear member, a carrier member and a ring gear member; a motor/generator; a stationary member; and a plurality of selectively engagable torque-transmitting mechanisms each engagable to connect one of the engine and the motor/generator for common rotation with one of the members of the planetary gear set, or to connect one of the members of the planetary gear set with the stationary member; said planetary gear set having one of said members continuously connectable for delivering torque to one of said front axle assembly and said rear axle assembly; wherein at least one of said engine and said motor/generator is alternately operatively connectable to said front axle assembly and said rear axle assembly by engagement of different ones of said torque-transmitting mechanisms for delivering torque to or receiving torque from said front axle assembly and said rear axle assembly, respectively; and wherein the torque-transmitting mechanisms are engagable in different combinations to provide different operating modes including an electric-only operating mode, and at least one electrically-variable operating mode. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A hydrid vehicle comprising:
-
a front drive axle assembly; a rear drive axle assembly; an engine; a transmission having; a motor/generator; a stationary member; a first and a second planetary gear set each having a ring gear member, a sun gear member, and a carrier member, at least one of the members of each planetary gear set being connected to a different one of said drive axle assemblies, respectively; and a plurality of selectively engagable torque-transmitting mechanisms; wherein said engine and said motor/generator are separately selectively connectable to one of said planetary gear sets by engagement of different ones of said torque-transmitting mechanisms to transfer torque to said drive axle assembly connected with said one of said planetary gear sets;
wherein the transmission is characterized by the absence of any additional motor/generator operable to transfer torque to any of the drive assemblies; andwherein said motor/generator is selectively connectable to the other of said said planetary gear sets by engagement of another one of said torque-transmitting mechanisms to transfer torque to the said drive axle assembly connected with said other of said planetary gear sets.
