Shock absorber
摘要:
A cushioning device particularly well suited for use in a draft gear of a railway vehicle comprises a plurality of rigid plates disposed one over the other and having symmetrically disposed non-porous elastomeric protuberances on each face thereof with interstices between the protuberances being filled with an elastomeric plastic foam which binds the elements together into a unitary structure.
