Abstract: A dual deflection ring system includes a pair of components that rotate relative to one another about an axis of rotation. One or more deflection rings are disposed between the components. The deflection ring(s) include two sets of pockets configured to provide two levels of compressibility in-series between the components. The two sets of pockets project radially relative to the axis of rotation and are compressible between the components.

Abstract: A sound reduction assembly includes a housing and a component supported via the housing. The component is movable relative to the housing. The sound reduction assembly includes a ring coupled to the component and the housing. The ring is configured to attenuate sound inducing vibrations in response to operation of the component. The ring includes a flange fixed relative to the housing to maintain a position of the ring relative to the component which maximizes attenuation of the sound in response to operation of the component. A method of utilizing a ring to attenuate sound inducing vibrations in response to operation of a component inside of a housing. A torque is selected to be applied to the ring. A stiffness of the ring is determined based on a stiffness-torque curve utilizing the selected torque to maximize attenuation of the sound. The ring is manufactured to meet the determined stiffness.

Abstract: A rotor shaft system for a vehicle includes a rotor shaft having a first shaft end opposite a second shaft end. The rotor shaft has a first segment and a second segment defined between the first shaft end and the second shaft end. The rotor shaft system includes a shaft gear coupled to the rotor shaft between the first shaft end and the first segment, and a shaft sleeve coupled to the first segment so as to surround a portion of the shaft gear. The rotor shaft system includes a lubrication system defined at least partially through the rotor shaft and the shaft sleeve. The lubrication system is to supply a fluid to at least a portion of the rotor shaft and the shaft sleeve.

Abstract: A powertrain component for a vehicle including a housing, and a mechanical system arranged in the housing. The mechanical system provides motive power to the vehicle. A passive sound enhancement system includes a bracket mounted to the housing. The bracket is selectively tuned to respond to one or more selected frequencies of the powertrain component.
