Train suspension device and suspended monorail train

A train suspension device, comprising a hoisting rod and a connection base, wherein a top of the hoisting rod is connected to a bogie, and a bottom of the hoisting rod is arranged on the connection base;

• a damping unit for connecting a bolster seam with the connection base comprises an inner supporting member, an intermediate buffer member and an outer supporting member which are nested successively from inside to outside, radial dimensions of an outer wall of the inner supporting member and an inner wall of the outer supporting member gradually decrease from one end to the other end in a vertical direction, and the intermediate buffer member, which is elastically deformable, is clamped between the inner supporting member and the outer supporting member;
• one of the inner supporting member and the outer supporting member is connected to the connection base, and the other one of the inner supporting member and the outer supporting member is connected to the bolster seam, which makes the inner supporting member and the outer supporting member have a tendency of approaching each other,
• wherein a vertically through supporting hole is defined on the connection base, and the supporting hole limits the installation of the outer supporting member;
• the radial dimensions of the outer wall of the inner supporting member and the inner wall of the outer supporting member gradually decrease from top to bottom;
• the inner supporting member is fixed relative to the bolster seam.
