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

The invention relates to a brake unit (3) for a catching device (2) of elevator systems (1) having a rolling element (28) on a rolling disk (27), which rolling element rolls on a stationary rolling track (20) of a braking and guiding rail (7) at least in some sections in the event of an activation. Furthermore, a brake lining (24, 26) is preferably provided, which interacts with a stationary braking track (21, 22) on the rail (7) as a result of the rolling of the rolling element (28) on the rolling track (20). In addition, at least one marking element (40, 41, 66) is provided, which produces a start marking (47) and an end marking (48) on the rolling track (20) and / or the braking track (21, 22) when the rolling element (28) rolls on the rolling track (20). Then the braking distance of the elevator cab (6) can be determined from the distance (49) between the start marking (47) and the end marking (48).

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...
