The invention discloses a rotary shock absorbing hanger, which mainly comprises a vehicle frame body (1) and a hanger body, wherein the vehicle frame body (1) consists of two parallel supporting surfaces (2 and 3) with holes and a turn positioning structure (4); the hanger body arranged between the two parallel supporting surfaces (2 and 3) comprises a circular tube of the hanger (8), a bracket of the hanger (10) and two turn positioning surfaces (14); a buffer block (17) is arranged between the turn positioning surfaces (14) and the turn positioning structure (4); a connecting piece (5) in acircular tube structure is arranged in at least one circular tube of the circular tube of the hanger and a supporting circular tube of an engine; a screw rod (20) is arranged in the connecting piece (5); and the two ends of the screw rod are sleeved with backing rings (21). The rotary shock absorbing hanger solves the problem of the overall vehicle vibration caused by the rigid connection among the hanger body, the vehicle frame and the engine.
