Title
(EN) DAMPER WITH FLEXIBLE FLOATING DISC
(FR) AMORTISSEUR À DISQUE FLOTTANT SOUPLE
Abstract
(EN)
A damper system for a vehicle including a pressure tube, piston assembly, and stroke dependent damper assembly. The stroke dependent damper assembly is coupled to a piston rod at a position below the piston assembly. The stroke dependent damper assembly includes a disc chamber that slidably receives a flexible floating disc. The disc chamber has proximal and distal chamber surfaces, which can include holes. The flexible floating disc is moveable between a first position where it contacts the proximal chamber surface and a second position where it contacts the distal chamber surface. The proximal chamber surface defines a proximal tapered cavity and the distal chamber surface defines a distal tapered cavity. The flexible floating disc is resilient and can flex into the proximal tapered cavity or the distal tapered cavity when it makes contact with the proximal chamber surface or the distal chamber surface.

L'invention concerne un système d'amortisseur destiné à un véhicule, comprenant un tube à pression, un ensemble piston, et un ensemble amortisseur dépendant de la course. L'ensemble amortisseur dépendant de la course est couplé à une tige de piston dans une position située au-dessous de l'ensemble piston. L'ensemble amortisseur dépendant de la course comprend une chambre à disque qui reçoit de façon coulissante un disque flottant souple. La chambre à disque est dotée de surfaces proximale et distale de chambre, qui peuvent comprendre des trous. Le disque flottant souple peut être déplacé entre une première position où il touche la surface proximale de chambre et une seconde position où il touche la surface distale de chambre. La surface proximale de chambre définit une cavité conique proximale et la surface distale de chambre définit une cavité conique distale. Le disque flottant souple est élastique et peut fléchir en entrant dans la cavité conique proximale ou la cavité conique distale lorsqu'il entre en contact avec la surface proximale de chambre ou la surface distale de chambre.
