Abstract
An elevator roller guide assembly that provides enhanced ride comfort. The assembly includes a chassis, a stop plate mounted to the chassis, a face wheel enclosure that at least partially encloses the face wheel and is connected to a plurality of leaf springs, and a pair of side wheel enclosures connected to the face wheel enclosure by the plurality of leaf springs. The side wheel enclosures each support a side wheel in a fixed relation to the other side wheel. The side wheel enclosures are operably connected to the stop plate by a pair of vertical plates. A multi-axis damper extends from the stop plate to engage the face wheel enclosure and dampen oscillation of the wheel enclosures during operation. A set of delta diameter wheels across all four guides reduces coincident flat spots to improve ride quality. Also, a wheel force gauge is integrated with the face wheel enclosure.
