Abstract: A launch device for coupling the rotary output of a prime mover to the rotary input of a driven device. The launch device includes a containment vessel defining a chamber. A driving element, located within the chamber and being rotatable relative to the containment vessel, is configured to be coupled to the output of the prime mover, while a driven element, also located within the chamber and being rotatable relative to the containment vessel, is configured to be coupled to the input of the driven device. The driven element is fluidically coupled to the driving element and is rotationally driven thereby during rotation of the driving element by the prime mover.

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.

Abstract: A launch device for rotationally coupling a prime mover to a transmission. The launch device includes a front and rear cover cooperating to define a chamber into which a plurality of blades extend forming an impeller. Located in the chamber and fluidically coupled to and rotationally driven by the impeller is a turbine. One or more roller bearings support the turbine and the rear cover for rotation about a central axis. The bearings include inner and outer members supporting the roller elements. A retention feature is further provided to aid in installation and retention of a support component with the bearing. The retention feature allows relative movement in an axial direction of assembly until the bearing and support components are fully engaged, but inhibits relative movement of the bearing and support components in an opposing axial direction.
