Abstract
An elevator system includes an elevator car with a plurality of roller guide assemblies attached thereto. The roller guide assemblies guide the elevator car vertically within a hoistway along a plurality of guide rails. Each roller guide assembly includes a friction damping subassembly to minimize vibration and lateral movement of the elevator car. The friction damping subassembly includes a grounding bar and a friction damper attaching onto a shaft of each roller in the roller guide assembly. The friction damping subassembly dissipates energy and improves the ride quality of the elevator car.
