The disclosure illustrates and describes a guide element which extends from a first end via a guide portion to a second end. The guide element has a fixing portion arranged at the second end and extending along a first extent direction, which runs transversely with respect to the axial direction, to a free end. The guide element has a connecting portion between the guide portion and the fixing portion. The connecting portion extends along a second extent direction, which runs transversely with respect to the axial direction and transversely with respect to the second extent direction, and extends along the axial direction from a first plane, which runs perpendicular to the axial direction, to a second plane, which runs perpendicular to the axial direction. The fixing portion is spaced apart in an axial direction both from the first plane and from the second plane. The disclosure furthermore relates to a corresponding brake anchor and to a corresponding disk brake system.

The invention proposes a disc brake having a brake caliper (1) and a tensioning device arranged therein for applying force to the brake linings of the disc brake, wherein part of the tensioning device is a brake lever (10) which can be actuated by a force element and preferably by a compressed air cylinder. The brake lever is composed of a lever arm (14), against which the force element is supported, and a brake application shaft (15), which is supported against a pressure piece (8) acting towards the brake linings, and is also supported from the inside against the brake caliper, wherein the brake caliper (1) and the brake application shaft (15) face each other and are formed as shells (21, 22) in which a supporting roller (20) with a roller axis (A) running transverse to the tensioning direction (Z) is mounted. To keep the mutual movability of the parts involved low by the simplest measures possible and without the need for additional parts, the supporting roller (20) is supported with the lateral surface (20A) thereof directly in one of the two shells (21, 22) and is designed to be non-rotatable or have only limited rotational movement with respect to this shell. The supporting roller (20) also serves as a means to centre the brake lever (10) laterally in the brake caliper. A supporting roller particularly suited to these purposes is also to be created.

For rapid and precise actuation of a friction brake, the thermal expansion of the friction brake is determined using a thermal model of the friction brake and therefrom the temperature-dependent shift in the contact point is determined for the braking operation and the temperature-dependent shift in the contact point is taken into account when determining the actuation measure of the friction brake to be adjusted.

An overspeed brake system for use in an elevator powerhead is provided. A brake rotor is attachable to a cable drum to rotate with a cable drum. A brake member selectively engages the brake rotor upon transition of an actuation lever from a first position to a second position. A biasing member acts on the actuation lever to bias the actuation lever from the first position towards the second position. A latch arrangement has a first orientation maintaining the actuation lever in the first position and a second orientation releasing the actuation lever for transitioning from the first position to the second position. The latch arrangement transitions from the first orientation to the second orientation when a speed sensing arrangement senses that the rotational speed of the cable drum is at least a predetermined rotational speed.

A disc brake (1) for motor vehicles includes at least two brake pads (25, 26), an application unit (4) with a setting spindle (5) arranged axially in the direction of the brake pads (25, 26), and a resetting device (7) for central adjustment of the setting spindle (5) after reaching a degree of wear of the brake pads (25, 26). The resetting device (7) has a housing (8), a sensor (9), a resetting shaft (10), and an adapter (11) with a decentral output (12). In one example, the adapter (11) has a cover (13) and a chain drive (14) for to transmitting an actuating movement from the decentral output (12) to the resetting shaft (10).
