A shock-absorbing and energy-collecting roller cage shoe including a base, a main energy-collecting module, two auxiliary energy-collecting modules, and a roller is provided. The base is provided with three containing spaces for containing the main energy-collecting module and the two auxiliary energy-collecting modules. In the three containing spaces, the main energy-collecting module and the two auxiliary energy-collecting modules are respectively connected fixedly to the base through wire rope shock absorbers, the main energy-collecting module and the two auxiliary energy-collecting modules are respectively pressed on the left side, the upper side and the lower side of the roller, and the right side of the roller is pressed on a cage guide.

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.

A roller guide assembly for an elevator device, the roller guide assembly comprising a base member having a mounting means for mounting to the elevator device, the base member comprising a shaft support member; a roller wheel for engaging a guide rail to be rolled on the guide rail; a shaft on which the roller wheel is bearing-mounted, the shaft being straight and non-rotatably supported by the shaft support member, and a vibration dampening element, the vibration dampening element comprising an elastomer body arranged between the shaft and the shaft support member for dampening vibration of the roller wheel and for isolating the vibration from the base member. The shaft is attached to the shaft support member by the vibration dampening element forming a single attachment point for the shaft. The elastomer body is configured to form an elastically spring-loaded universal joint for the attachment of the shaft to provide a universal degree of freedom of an angular movement of the shaft and the roller wheel in relation to the base member.

A damper unit for an elevator for reducing vertical vibrations of an elevator car of the elevator during a standstill includes a stamp-like acting element that acts on an end-face guide surface of a guide rail. The acting element is spaced from the guide rail in an idle position and can be connected slip-free to the guide rail by an eccentric drive in an active position. Force transmitting elements containing a shock damper for damping the motions of the elevator car during a standstill of the car adjoin the acting element.

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.
