Abstract: A drive system includes first and second power sources, a planetary gearset including an output, and first and second inputs driveably connected, respectively, to the first and second power sources, a pinion supported for rotation, and a synchronizer for alternately releasing a drive connection between the pinion and output and substantially synchronizing a speed of the pinion and a speed of the output before driveably connecting the pinion and the output.

Abstract: The present invention relates to a transmission for an automotive vehicle having a clutch retainer assembly or thrust bulkhead fixedly secured to the transmission housing and interdisposed between the reverse clutch assembly and the fourth clutch assembly. A pair of thrust bearing assemblies are interdisposed between the clutch assemblies and the thrust bulkhead to transfer the axial thrust loads generated by the multiple planetary gear assemblies through the thrust bulkhead to the transmission housing.

Abstract: A torque converter has a turbine and a pump with elastomeric linings on its core and shell surfaces proximate to the blades. The elastomeric linings are deformed where the blades engage the core and shell surfaces. This localized deformation effects a seal between the blades and the core and shell surfaces. This seal eliminates leakage between the blades and the cores and the shells, thereby increasing torque converter efficiency.

Abstract: A friction disc test machine has a cavity in which alternately spaced stationary and rotary friction discs are disposed. The friction discs are urged into engagement by a selectively actuatable fluid operated piston to bring the rotating discs to a halt. An end cover and balance reaction piston are provided to limit the axial disc movement. The balance reaction piston is slidably disposed in a cavity formed in the end cover for linear and angular movement relative thereto. One friction disc abuts the balance piston whereby, due to the alignment properties of the piston, all of the friction discs are maintained in parallel alignment during engagement therebetween.
