Abstract
A roller guide for guiding a car of an elevator system along a guide rail may include a roller carrier that can be attached to the car and several rollers disposed on the roller carrier. The roller may be configured to roll by their respective running surface on a rolling surface of the guide rail. The rollers may each be mounted movably in the roller carrier with a direction component perpendicular to the rolling surface of the guide rail. The rollers may be mounted in operative connection with one another at least in part by way of hydraulic fluid such that a movement of one of the rollers perpendicular to the rolling surface of the guide rail causes a directionally-opposite movement of at least a second of the rollers. The present disclosure also concerns a car and an elevator system that employ such roller guides.
