International Classification:

B60G 15/06

US Classification:

267220

Abstract:

A mount assembly for a suspension damper is provided which includes a piston rod extending about an axis and a mount housing. A jounce bumper is axially positioned about the piston rod and has an end surface and a radially outer surface. The jounce bumper is formed of a first deformable material selectable for absorbing energy from an axial force applicable through the piston rod. A jounce bumper cup formed of a second deformable material selectable for absorbing additional energy fits onto the end surface of the jounce bumper. The jounce bumper cup has a wall portion extending sufficiently around the radially outer surface of the jounce bumper to retain it in position and a load mount portion extending to the mount housing and being configured to absorb the additional energy.

International Classification:

G10K 11/175
F25D 17/06

Abstract:

Methods and systems for reducing a pressure wave are provided. In an exemplary embodiment, a motor vehicle comprises a cabin and a receiver positioned to detect an input pressure wave within the cabin and produce an input signal. A fan with a blade having a variable pitch is positioned within the vehicle where the fan is audible within the cabin. A processor is in communication with the receiver and the fan, where the processor is configured to receive the input signal and determine an input frequency and an input phase. The processor is further configured to instruct the fan to control a pitch of the blade to produce a cancellation pressure wave with a cancellation frequency that is about the same as the input frequency and a cancellation phase that is about 180 out of phase with the input phase.

International Classification:

B60R 13/08
G10K 11/168
B62D 25/06

Abstract:

A panel assembly includes a first panel defining a surface, and a boom attenuation panel. The boom attenuation panel includes a circumferential edge, and a central portion. The boom attenuation panel is attached to the surface of the first panel, along the circumferential edge of the boom attenuation panel. The central portion of the boom attenuation panel is spaced from the surface of the first panel a gap distance to form a gas chamber between the surface of the first panel and the central portion of the boom attenuation panel. The gas chamber contains a gas that is moveable within the gas chamber in response to wave-like motion of the first panel. Movement of the gas increases the effective acoustic mass of the boom attenuation panel, and damped the wave-like motion of the first panel, which operates to reduce noise generated from the wave-like motion of the first panel.
