Title:
SUSPENSION DEVICE
Document Type and Number:
Japanese Patent JP2023069345
Kind Code:
A
Abstract:
To suppress a suspension device from being bulky.SOLUTION: A suspension device comprises: a double cylindrical upper base 11; a double cylindrical lower base 12; an inner member 13 connected to an upper end part of a rod 52 of a damper 51; a first elastic body 14 and a second elastic body 15 that independently connect inner cylinders 21, 25 included respectively in the upper base and the lower base, to the inner member; a third elastic body 16 that connects outer cylinders 22, 26 included respectively in the upper base and the lower base, to each other; and a supply/discharge mechanism 17 which supplies/discharges pressurized air to/from an air chamber X surrounded by the upper base, the lower base, the first elastic body, the second elastic body, and the third elastic body. In association with the supply/discharge of pressurized air to/from the air chamber, the first elastic body, the second elastic body, and the third elastic body expand and contract while elastically deforming, to move the upper base and the lower base relatively in a vertical direction. When the supply/discharge mechanism discharges the pressurized air from the air chamber, the upper base and the lower base relative approach in the vertical direction while the first elastic body, the second elastic body, and the third elastic body are compressively deformed.SELECTED DRAWING: Figure 1
