| 摘要 |
<p>The invention concerns a semirigid suspension (1), in particular for a motor vehicle wheel, consisting of at least three arms (11, 12, 13), flexible in bending and rigid in traction-compression, connected with one another in one end (1911, 1912, 1913) where they merge into an inter-arm connection (19) whereof the vertically projected surface is inscribed inside a polygon assembling the free ends of the adjacent arms, each of said ends being linked by a connection (15, 16, 17) to a member oscillating mainly in a vertical direction and secondarily in a longitudinal direction, each arm being linked to the part of the body (3) to be isolated from vibrations by a flexible link (611, 612, 613), said structure being anisotropic of the vertical mode oscillation. The invention is characterized in that it is isotropic of the longitudinal mode oscillation. The inter-arm connection (19) is made of an elastomeric material, a pneumatic actuator (1920) being arranged between the inter-arm connection (19) and the part of the body (3) to isolated from vibrations.</p> |
