Damper device for a mechanical system
First Claim
1. A damper device of the type comprising:
- a first assembly (100) and a second assembly (300) guided in relative displacement, said first assembly being tied to a reference and said second assembly being movable relative to said reference;
means (113) defining a driving connection between said second assembly and a system to be damped;
a shoe (400) resting against said first assembly; and
control means (500) including buckling resilient means (510) interposed between the shoe (400) and said second assembly, said control means being adapted to exert a force on the shoe (400) tending to urge said shoe against said first assembly during an active stage of damper device loading corresponding to a first direction of relative displacement between said first and second assemblies (100,
300), and to reduce the force exerted by the shoe (400) during a passive stage of damper device loading corresponding to a second direction of relative displacement between said first and second assemblies (100,
300),wherein the resilient means (510) are composed of beams which are rectilinear in a standby position, and which rest by the ends respectively on the shoe and on said second assembly.

Abstract
A damper device comprising a first and second assembly suitable for guided relative displacement. The first assembly is supported stationarily with respect to a reference. The second assembly is supported for guided relative displacement with respect to the first assembly and the reference. A driving connection connects the second assembly and a system to be damped. A shoe rests against the first assembly and a resilient control that works in buckling is interposed between the shoe and the second assembly. The resilient control exerts a force on the shoe tending to urge the shoe against the first assembly during an active stage of damper device loading, corresponding to relative displacement in a first direction between the first and second assemblies and to reduce the force exerted by the shoe during a passive stage of damper device loading corresponding to relative displacement in a second direction between the first and second assemblies.

- 36. A damper device comprising a first assembly supported stationarily with respect to a reference, a second assembly supported for guided relative displacement with respect to said first assembly and said reference, means forming a driving connection between said second assembly and a movable system to be damped, a shoe spaced from said first assembly and movably and frictionally engaging said second assembly, resilient control means interposed between said shoe and said first assembly, said resilient control means exerting a force on said shoe to urge said shoe frictionally against said second assembly to dampen movement of said second assembly during an active stage of damper device loading corresponding to a first direction of movement of the second assembly and reducing force exerted on said shoe to reduce frictional engagement of the shoe against the second assembly to reduce damping movement of the second assembly during a passive stage of damper device loading corresponding to a second direction of movement of the second assembly, said resilient control means including a buckling part engaged between said shoe and said first assembly to exert a force on the shoe toward the second assembly when the second assembly is moved in said first direction of movement.
