An overspeed governor assembly comprises an overspeed governor, and a linkage (3) provided to enable the overspeed governor to associate with a safety device of the elevator, when an elevator car overspeed is occurring, to trigger the safety device to perform safety measures. At least one torsion spring is coupled between a sheave (1) and a centrifugal mechanism (4) in the overspeed governor for providing a pre-set load, and the centrifugal force formed by the centrifugal mechanism (4) when the elevator car overspeed is occurring, is greater than the pre-set load, for triggering the safety device via the linkage. The assembly and system are easy to be installed, manufactured and maintained. The pre-set spring load in the overspeed governor can be conveniently and flexibly set and adjusted, thereby effectively enhancing the safety and reliability of the elevator system.
