Abstract
A launch device coupling a prime mover to a transmission. The launch device includes a front cover for connecting to the output of the prime mover and an output hub for connecting to the input of the transmission. A rear cover is connected to the front cover and cooperates to define a chamber. Within the chamber are an impeller and a turbine having a plurality of opposing blades such that hydraulic fluid is directed from the impeller blades and toward the turbine blades. A main damper is provided between the turbine and output hub of the launch device. Coupled to the main damper is a lock-out clutch configured to releasably lock the main damper for rotation with one of the front and rear covers. The launch device also includes an active dynamic damper system coupled to the main damper and configured to reduce resonance influence on the main damper.
