Hydraulic system for transmission of forces between an aircraft turboprop and an attachment device

摘要

This invention relates to a force transmission system (50) between a turboprop and an attachment pylon, comprising:a first and a second force transmission device (52a, 52b) each comprising a first hollow cylinder (54) with an axis (56) that will be made parallel to a first force transmission direction, said first cylinder defining a first space (58) full of a fluid (60) and closed off in a sealed manner at its two opposite ends, by a first damping layer (62) that will bear in contact with a bearing element (66) of the turboprop, and by a second damping layer (64) that will bear in contact with a bearing element (68) of the attachment device, said first and second layers possibly being compressed by the pressure of said fluid; andfirst means (70) of fluid communication between the two spaces (58, 58).
