Problems solved by technology

[0014] Since the damper plate is not preloaded when the armature disc is in the lowered state, the switching noise that occurs when the armature disc is attracted to the coil bracket cannot be effectively suppressed
[0015] The damper plate is presented as a stamped / bent part, which also has unnecessary errors in its dimensional accuracy

Embodiment Construction

[0052] figure 1 Shows a perspective view of an electromagnetically released spring pressure brake (FDB) consisting of two brake circuits acting on the same rotor (7) in a fail-safe configuration. This is a common design for redundant fail-safe brakes in passenger lift areas. In the variant of the spring pressure brake (FDB) shown here, two parallel-aligned armature disks (1) are assigned to the coil carrier (3). The coil carrier (3) contains individual magnetic coils (5) and individual compression springs (4) for each armature disc (1). In this example, the spring pressure brake (FDB) is screwed to the motor endshield (M) using several screws (11). In addition, a flange plate (2) is provided between the motor end cover (M) and the rotor (7).

[0053] Figure 1.1 shows a complete cross section, which is staggered through the figure 1 Two brake circuits are shown. The coil carrier (3) containing the compression spring (4) and magnetic coil (5) is rigidly mounted on the mot...

Abstract

An electromagnetically switchable brake, preferably spring-loaded brake, comprising at least one coil carrier (3) and at least one armature plate (1), wherein the axial distance of the coil carrier and armature plate relative to one another is variable, comprising at least one rotor (7) on at least one hub of a shaft to be braked, and comprising damping members arranged between the armature plate (1) and coil carrier (3), between the end faces of the coil carrier (3) and armature plate (1) which face one another. It is considered to be novel and inventive that the solid body of coil carrier (3) and / or armature plate (1) has an integral damper structure (D), which is composed of at least one elastic tab (12) and a foot (13), the elastic tab (12) being an integral part of the solid body of the armature plate (1) or of the coil carrier (3) (figure 1.1).

Description

technical field [0001] The invention relates to an armature disc or coil carrier according to the preamble of the main claim, having an integral damper structure for fail-safe brakes and operating current brakes. In this case, the fail-safe brake preferably comprises a friction brake, for example an electromagnetically released spring pressure brake or a permanent magnet brake. Background technique [0002] A fail-safe brake is generally understood to mean a braking system that produces a braking effect without an external energy supply, ie in a state without current. Working current brakes work on the opposite principle. An operating current brake is therefore generally understood to be a braking system that requires an external energy supply in order to be able to exert its braking effect. This includes in particular so-called pole-surface brakes. [0003] Among other things, fail-safe current brakes are used in noise-sensitive applications. These include, for example,...
