Problems solved by technology

However, the colorants used then affect the friction properties and thus the brake slip
The mentioned processes or methods thus have the common disadvantage that the determined brake slip is prone to a large degree of inaccuracy or a large degree of measurement error or even the function of the brake can be affected

Embodiment Construction

[0031] figure 1 An elevator installation 1 with a safety brake 2 comprising at least one brake unit 3 , trigger device 4 and trigger cable 5 according to a first embodiment is shown schematically and in detail.

[0032] The elevator installation 1 includes an elevator car 6 . The elevator car 6 is used to receive people and / or objects. The transport of people, luggage etc. can thus be carried out, or the lift arrangement 1 can also be used as a goods elevator 1, for example for transporting goods.

[0033] The brake unit 3 of the safety brake 2 cooperates with the guide rail 7 . Rail 7 schematically passes through the dotted line at figure 1 is illustrated in. In the present exemplary embodiment, the elevator car 6 is guided evenly at or along the guide rails 7 by means of guide shoes. In the present exemplary embodiment, the guide rail 7 is thus configured as a brake and guide rail 7 .

[0034] In a modified embodiment, the guide rail 7 cooperating with the braking unit...

Abstract

A brake unit for a safety brake of an elevator system has a rolling element on a rolling disk, which rolling element rolls on a stationary rolling track of a braking and guiding rail at least in some sections in the event of an activation of the safety brake. A brake lining of the brake unit interacts with a stationary braking track on the rail as a result of the rolling of the rolling element on the rolling track. At least one marking element on the rolling element produces a start marking and an end marking on the rolling track and / or the braking track when the rolling element rolls on the rolling track. Then the braking distance of the associated elevator car can be determined from the distance between the start marking and the end marking.

Description

technical field [0001] The invention relates to a method for determining the braking slip of a braking unit or of an elevator car braked by the braking unit. Background technique [0002] A braking fall arrest device for elevators is known from EP0899231A1. Known braking arrestors comprise brackets which engage around guide rails for the elevator car and are arranged in transverse direction relative to the guide rails. In addition, two brake caliper heads supported on the bracket are arranged on both sides of the guide rail. One of the caliper heads serves as the active caliper head. The other caliper tip acts as a passive caliper tip. In this case, the active brake caliper head is supported by the working eccentric, which is connected with the rolling disc to prevent relative rotation. The rolling disc and the working eccentric can rotate around a common fulcrum pin. In that respect, the rolling disc and the working eccentric together form the viscous actuating element...
