Reduced noise decoupler

Номер: US20130292889A1
Автор: Douglas L. Power
Принадлежит: Cooper Standard Automotive Inc

A reduced noise decoupler has a perimeter with a wavy form. This provides a significant reduction in the initial contact noise. Hydraulic pressure deforms the wavy edges, pressing the wavy edge flat and creating the necessary seal. The edge geometry is created such that pressure will flatten the decoupler perimeter without creasing, ensuring a proper seal without losses. This is achieved by drawing the wavy detail from the perimeter to an interior of the decoupler body in alternating fashion to create a pattern of peaks and troughs bounded by thicker sections, allowing the edges to easily deform without creasing.

Rate-dependent, elastically-deformable devices according to various embodiments can be stretched and recovered at low elongation rates. Yet they become stiff and resistive to stretching at high elongation rates. In one embodiment, a rate-dependent, elastically-deformable device includes an elastically-deformable confinement member; one or more filaments placed inside the elastically-deformable confinement member; and a fluid that substantially fills the remaining volume inside the elastically-deformable confinement member. The resistance force to extension of the device is designed to increase as the extension rate of the device increases. At low elongation rates the filaments can readily slide past each other. At high elongation rates, the fluid transforms to a less flowable material that greatly increases the force and energy required for elongation; or transforms to a non-flowable material that resists elongation. The devices thus can be stretched and recovered at low elongation rates, but become extremely stiff and resistive to stretching at high elongation rates. 1. A rate-dependent , elastically-deformable device comprising:an elastically-deformable confinement member;one or more filaments placed inside the elastically-deformable confinement member; anda fluid that substantially fills the remaining volume inside the elastically-deformable confinement member,wherein the resistance force to extension of the device increases as the extension rate of the device increases.2.

Airplane Shock Absorbing Suspension

Автор: Roberts John Charles

A landing gear strut incorporating an oleo-pneumatic shock absorber with a bungee return spring. An oleo-pneumatic shock absorber is a device engineered for slowing down a moving mass. The shock absorber converts the kinetic energy of the impact into heat due to the friction of oil being driven through narrow orifices. The shock then recovers using air and or spring pressure. The recovery is governed by the flow rate of the fluid to the original reservoir. In the case of an aircraft this results in less bounce, shorter stop time, smoother overall ride, and safer landings. 1) An airplane landing gear suspension comprising:a) A static or fixed strutb) A dynamic or sliding strutc) A cabane “v” attachment means as a fixed part of the static strutd) An axle connection as a fixed part of the dynamic strute) A bungee hook or retainer fixed to the static strut as a means of connecting a return assist springf) A bungee hook or retainer fixed to the dynamic strut as a means of connecting a return assist springg) A return assist spring connected to the static and dynamic struts via bungee hooks or retainersh) A bracket fixed to the static strut as a means of mounting or connecting a shock absorberi) A bracket fixed to the dynamic strut as a means of mounting or connecting a shock absorberj) A pushrod and guide sleeve to operate the return assist springk) A shock absorber connected to the static and dynamic struts via brackets2) An airplane landing gear suspension of where a static strut incorporates:a) A slot or hole to allow a connection from the inner dynamic strut to a mounting bracket or connection fitting for a shock absorber and return assist spring.b) A attachment means to connect to the cabane “v”c) A mounting bracket to connect the lower end of a shock absorberd) A bungee hook to retain a return assist spring3) An airplane landing gear suspension of where the dynamic strut incorporates:a) A attachment means for connecting to the axleb) A means for connecting to a ...

An assembly for magnetically dynamic damping useful for isolating vibrational forces includes a housing wall bounding a main chamber therein. The assembly further includes a fixed magnetic source disposed in the main chamber. A diaphragm of elastic material is disposed in the assembly impermeably dividing the main chamber into sub-chambers. The diaphragm includes a magnetically actuated element adjacent to the fixed magnetic source. A source of electrical current energizes the magnetically actuated element, the fixed magnetic source, or both and either repels or pulls the magnetically actuated element with respect to the fixed magnetic source. A magnetic guide surrounds the fixed magnetic source and defines a gap exposing the fixed magnetic source to the magnetically actuated element. The magnetic guide routes the magnetic field towards the gap and prevents outward magnetic interference to the rest of the assembly. 1.
