Shock and torsion absorber for elevated vacuum suspension

A shock and torsion absorber, comprising:

• a base member having an accommodation space and an exhaust opening;
• a cushion member joined to a bottom end of the base member comprising a casing, a shaft limit element, an elastic element, and an adjustment element, where the shaft limit element and the elastic element are sequentially received in the casing, and a bottom end of the casing is sealed by the adjustment element;
• a limit member comprising a tubular positioning element and a seal element, where a bottom end of the positioning element is threaded through the base member and coupled to the cushion member, and the seal element is joined to a top end of the positioning element;
• a joint member comprising an intake element, a trough, and an axial channel, where the intake element is joined to an outer circumference of the joint member to draw air inside the joint member, the trough is around an inner circumference of the joint member, a piston is tightly housed in the joint member through the trough, a shaft runs through the axial channel and the positioning element, and joins to the shaft limit element for buffering pressure exerted on the joint member
• wherein an upper vacuum chamber is formed inside the joint member above the seal element, and a lower vacuum chamber is formed inside the joint member between the piston and the seal element;
• when the joint member moves upward, the intake element draws air into the upper vacuum chamber and air in the lower vacuum chamber is expelled through the exhaust opening;
• and, when the joint member moves downward, air in the upper vacuum chamber flows to the lower vacuum chamber.
