ANTIVIBRATION SUSPENSION SYSTEM FOR A TIE BAR OF AN AIRCRAFT POWER TRANSMISSION GEARBOX, AN ANTIVIBRATION SUSPENSION SYSTEM, AND AN AIRCRAFT

摘要

An antivibration suspension system of an aircraft, the antivibration suspension system comprising a lever and an oscillating mass. The antivibration suspension system comprises a mechanical motion amplifier device interposed between the lever and the oscillating mass, the motion amplifier device being provided both with a mechanical inlet constrained to move in rotation with the lever about a control axis and with a mechanical outlet driving rotary movement of the oscillating mass.

主权项

1. An antivibration suspension system for suspending a tie bar of a power transmission gearbox of an aircraft, the antivibration suspension system comprising a lever suitable for being hinged to the tie bar, the antivibration suspension system including an oscillating mass, wherein the antivibration suspension system comprises a mechanical motion amplifier device interposed between the lever and the oscillating mass so that a first rotary movement of the lever through a first angle about a control axis induces a second rotary movement of the oscillating mass through a second angle, the second angle being greater than the first angle, the motion amplifier device being provided both with a mechanical inlet constrained to move in rotation with the lever about the control axis and with a mechanical outlet driving rotary movement of the oscillating mass.
