Embodiment Construction
[0030] FIG. 1 shows a power flow diagram of an exemplary drive system 10 including an internal combustion engine 12 , a shock absorber 14 , a planetary gear set 16 , an electric machine 18 and an automatic transmission 20 . Both the internal combustion engine 12 and the electric machine 18 drive an automatic transmission 20 through a planetary gearset 16 . The electric motor 18 also drives a fluid pump 22 of an automatic transmission 20 .
[0031] More specifically, in the example shown, the drive system 10 is provided in the form of a parallel hybrid drive in which the internal combustion engine 12 has a mechanical drive connection to an automatic transmission 20 . Referring to FIG. 1 , the crankshaft 24 of the internal combustion engine 12 is connected to a shock absorber 14 that serves to reduce pulsation caused by the intermittent bursts of the internal combustion engine 12 . Shock absorber 14 is connected to a planet carrier 28 of planetary gear set 16 by a shaft 26 . R...
