Abstract
A drive assembly for a vehicle drive train includes a base assembly including a base hub configured for non-rotatably connecting to an outer circumferential surface of a transmission input shaft. The base assembly includes a torsional damper fixed to the base hub. The torsional damper includes an input section and an output section drivingly connected by springs. The springs allow relative rotation between the input section and the output section. The output section of the torsional damper is non-rotatably fixed to the base hub. The drive assembly also includes a raw hub extension configured for non-rotatably connecting to an engine crankshaft. The raw hub extension is non-rotatably fixed to the input part of the torsional damper at an engine side of the torsional damper. The torsional damper allows relative rotation between the raw hub extension and the base hub.
