Title
(EN) SUSPENSION DEVICE
(FR) DISPOSITIF DE SUSPENSION
(JA) サスペンション装置
Abstract
(EN)
A suspension device (S1) according to the present invention comprises: a single-rod-type shock absorber main unit (D1) that comprises a cylinder (1), a piston (2) movably inserted into the cylinder (1), an extension-side chamber (R1) and a compression-side chamber (R2) within the cylinder (1), the extension-side chamber (R1) and the compression-side chamber (2) being partitioned by the piston (2), and a piston rod (3) linked to the piston (2) which is movably inserted into the cylinder (1), and that exhibits damping force by fluid entering and exiting the cylinder (1) when the single-rod-type shock absorber main unit (D1) extends and compresses; a suspension spring (8) that biases the shock absorber main unit (D1) in the extending direction; a compression chamber (R3) that communicates with the compression-side chamber (R2) and compresses within inside of the cylinder (1) that is under biasing force from the suspension spring (8); and a fluid supply-and-discharge source (F) that is capable of supplying and discharging fluid to and from the compression chamber (R3).
(FR)
La présente invention concerne un dispositif (S1) de suspension comportant: une unité principale (D1) d'amortisseur à tige unique qui comporte un cylindre (1), un piston (2) inséré de façon mobile dans le cylindre (1), une chambre (R1) côté allongement et une chambre (R2) côté compression à l'intérieur du cylindre (1), la chambre (R1) côté allongement et la chambre (R2) côté compression étant séparées par le piston (2), et une tige (3) de piston liée au piston (2) qui est insérée de façon mobile dans le cylindre (1), et qui exerce une force d'amortissement du fait d'un fluide entrant dans le cylindre (1) et quittant celui-ci lorsque l'unité principale (D1) d'amortisseur à tige unique s'allonge et se comprime; un ressort (8) de suspension qui sollicite l'unité principale (D1) d'amortisseur dans le sens de l'allongement; une chambre (R3) de compression qui communique avec la chambre (R2) côté compression et se comprime à l'intérieur du cylindre (1) qui subit la force de sollicitation du ressort (8) de suspension; et une source (F) d'amenée et d'évacuation de fluide qui est capable d'amener et d'évacuer du fluide jusqu'à la chambre (R3) de compression et à partir de celle-ci.
