Abstract: A noise vibration harshness reduction assembly includes a housing, a component, and an axial ring. The component is supported via the housing and movable relative to the housing. The axial ring is disposed axially along the component. The axial ring is configured to attenuate axial sound inducing vibrations in response to operation of the component.

Abstract: A method of resistance welding first and second parts formed of dissimilar materials includes disposing a first electrode on a side of the first part and a second electrode on a side of the second part. Grooves separated by raised portions are formed in a faying surface of the second part. Pressure is applied to the first and second parts via the set of electrodes, and the parts are heated via the electrodes to form a joint between the parts. A welded assembly includes metallic first and second parts welded together. The second part may have a faying surface defining a number of grooves separated by raised portions. The faying surfaces of the parts may be disposed at 10-80 degree angles with respect to a first part axis (and/or a welding pressure axis).

Abstract: A vehicle propulsion system includes an oncoming condition sensor that generates an oncoming condition signal, a continuously variable transmission with a variator assembly adapted to transfer torque between a first rotating member and a second rotating member through a flexible continuous device rotatably coupling the first rotating member to the second rotating member, one of the first rotating member and second rotating member including a clamping pulley adapted to controllably adjust a clamping force on the flexible continuous device, and a controller in communication with the oncoming condition sensor and the continuously variable transmission that is programmed to characterize an oncoming condition based upon the oncoming condition signal and to control the clamping pulley to adjust the clamping force based on the characterization of the oncoming condition.
