Abstract
An overspeed governor assembly for an elevator system, an elevator safety system, and an elevator system. The overspeed governor assembly comprises an overspeed governor, a linkage 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, and at least one torsion spring coupled between a sheave and a centrifugal mechanism in the overspeed governor for providing a pre-set load, and the centrifugal force formed by the centrifugal mechanism when the elevator car overspeed is occurring, is greater than the pre-set load, for triggering the safety device via the linkage.

An overspeed governor assembly for an elevator system, comprising:
- an overspeed governor;
- and
- a linkage 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;
- characterized in that the overspeed governor comprises at least one torsion spring coupled between a sheave and a centrifugal mechanism in the overspeed governor for providing a pre-set load, and the centrifugal force formed by the centrifugal mechanism when the elevator car overspeed is occurring, is greater than the pre-set load, for triggering the safety device via the linkage.
