SUSPENSION DEVICE
Document Type and Number:
Japanese Patent JP2020192935
Kind Code:
A
Abstract:
To provide a suspension device whose structure can be simplified.SOLUTION: A suspension device 1 comprises a leaf spring S and a damper 2. The leaf spring S imparts elastic force for relatively moving a spring lower member in a predetermined direction with respect to a body B (a spring upper member) of a vehicle V. The damper 2 has a first expanding/contracting member 10, a second expanding/contracting member 20, an intermediate member 30 and a damping passage 40. The first and the second expanding/contacting members 10 and 20, in which a first gas chamber R1 and a second gas chamber R2 which are filled with gas are formed, can expand and contract. Upper ends 10A and lower ends 20B of the first expanding/contracting member 10 and second expanding/contracting member 20 are connected to the body B. The intermediate member 30 connects the first and the second expanding/contracting members 10 and 20 to each other, and is contacted to the leaf spring S. The damping passage 40 communicates the first and the second gas chambers R1 and R2 with each other, and imparts resistance to flow of gas flowing. When an either of the first and the second expanding/contracting members 10 and 20 expands, the other contracts.SELECTED DRAWING: Figure 2
