Embodiment Construction

[0030] figure 1 An elevator is shown with a vertically movable car 2 for transporting people or goods. A carrier 34 , for example in the form of a belt or a rope, is used as carrier for moving the car 2 . For guiding the cage 2, the elevator system has two guide rails 3 extending in the vertical direction of travel z. In this case, each guide rail 3 has three guide surfaces extending in the direction of travel of the car. Installed on the car 2 figure 1 The guide shoe is configured as a roller guide shoe by way of example. Undesirable vertical vibrations of the car during parking can be dampened by means of the damping unit designated 1 . Such vertical vibrations are generated when a person steps on or off the car 2 . The car 2 is subject to vibrations due to load changes. This phenomenon is particularly pronounced in elevators based on carrier belts with very high shaft heights. The direction along which the guide rail extends is marked by z, the arrow z likewise marks...

Abstract

A damping unit (1) for a lift, for reducing vertical oscillations of a car (2) when at a standstill, has brake-shoe holders (8, 8') provided with brake shoes (7, 7'). The brake-shoe holders (8, 8') are connected to a common electric motor (4) via a toothed-gearing mechanism. The toothed-gearing mechanism has a central driving gearwheel (11), which adjoins a drive shaft (17) of the motor (4), and eccentric gearwheels (12, 12'), which are each assigned to a brake shoe (7, 7') and are in operative connection with the driving gearwheel (11). The brake shoes (7, 7') are supported resiliently on the respective brake-shoe holder (8, 8') in each case via two helical compression springs (5).

Description

technical field [0001] The invention relates to a buffer unit for an elevator. The elevator comprises a car which can be moved in the elevator shaft by means of a drive unit via support means, for example in the form of load-bearing ropes or load-bearing belts. Guide rails are fastened in the elevator shaft, which guide rails provide a linear guide for the elevator car. People or goods stepping into or leaving the elevator car during parking of the car cause undesired vertical vibrations of the car due to the elasticity of the supporting mechanism. Such vertical vibrations occur especially in elevators which use carrying belts as the load-carrying mechanism, which have recently become more and more popular. Since belts have a less favorable vibration behavior than steel cables, vertical vibrations increasingly have a negative effect on passenger comfort and operating safety. Background technique [0002] A device for preventing vertical vibrations of the elevator car duri...
