Abstract
Provided is a suspension system capable of expanding one of an oil chamber and a gas chamber of an intermediate unit and contracting the other when a damper compresses or expands without generating friction in the intermediate unit. The intermediate unit includes an intermediate case having an intermediate oil chamber connected to an oil chamber of a right damper and the oil chamber of a left damper and an intermediate gas chamber, and a diaphragm made of a flexible material, which partitions the intermediate oil chamber and the intermediate gas chamber.
Claims18
A suspension system, comprising:
- a first damper having a cylinder in which an oil chamber is formed;
- a second damper having a cylinder in which an oil chamber is formed;
- and
- an intermediate unit including a case which includes an intermediate oil chamber connected to the oil chamber of the first damper and the oil chamber of the second damper and an intermediate gas chamber, the intermediate unit further including a diaphragm formed of a flexible material which partitions the intermediate gas chamber from the intermediate oil chamber;
- wherein the case has a cylindrical main body which includes an open end portion and a lid member which is disposed inside the open end portion to close the open end portion, and
- the diaphragm has an outer peripheral edge of which a position is fixed, the outer peripheral edge being sandwiched and fixed between an outer peripheral surface of the lid member and an inner surface of the cylindrical main body, and the diaphragm has a shape bulging from the outer peripheral edge toward the intermediate oil chamber.
