Spring-Loaded Brake Switch Adjustment via Adjustable Lever
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for arranging and adjusting microswitches or non-contact proximity switches in electromagnetically actuated spring-loaded brakes are cumbersome, requiring good accessibility and sensitivity, and often necessitate a final check using specialized tools, especially in confined spaces.
Innovation Solution
Attaching the microswitch or proximity switch to a stationary element and using an adjustable lever on the armature disk to set the abutment or reference point for the switching plunger, allowing for adjustment from one side and eliminating the need for a final check.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the microswitch is mounted on the housing side on the stationary element with adjustment via elongated holes, then the switch can be adjusted, but good all-round accessibility and high sensitivity are required, increasing complexity
Solution Approach 1:
An adjustable lever mounted on the armature disk serves as an intermediary element between the stationary microswitch and the moving armature disk. The lever translates the small movement of the armature disk into a larger displacement at the microswitch plunger, enabling adjustment from one side only and eliminating the need for good all-round accessibility while maintaining high sensitivity
Solution Approach 2:
The adjustment mechanism is relocated from the housing side to the armature disk side, changing the dimension of adjustment accessibility from radial (all-around) to axial (one-side). The lever pivots on the armature disk and extends towards the microswitch, allowing adjustment operations to be performed from a single direction
2Ease of operation
If the microswitch is firmly attached to the stationary element with an adjustable lever on the armature disk, then adjustment from one side is enabled, but the lever mechanism increases device complexity
Solution Approach 1:
The adjustable lever serves multiple functions: it acts as a mechanical linkage between the armature disk and microswitch, provides adjustment capability from one side, and serves as the reference point for microswitch actuation. This multi-functionality justifies the additional component by eliminating the need for elongated holes and complex housing-side adjustment mechanisms
3Manufacturing precision
If traditional adjustment methods are used, then the microswitch can be positioned, but a final check using feeler gauges or special tools is necessary, increasing time consumption
Solution Approach 1:
The adjustable lever on the armature disk serves as its own reference point and adjustment indicator. When the lever is positioned correctly, it automatically provides the reference point for microswitch actuation, eliminating the need for external checking tools like feeler gauges. The system self-verifies the adjustment through the lever's position relative to the microswitch plunger
Solution Approach 2:
The lever is pre-adjusted to the correct position during assembly, establishing the reference point for microswitch actuation before final installation. This preliminary positioning ensures that no further adjustment or checking is needed after installation, as the lever's position inherently verifies correct alignment

AI summary
The invention relates to an arrangement for monitoring the switching state for spring-loaded brakes (FDB) that are actuated by a closed-circuit current. The axial displacement of the armature disk (3) of the spring-loaded brake, said axial displacement occurring during a switching cycle of the spring-loaded brake, is scanned by a mechanical microswitch (6) or by a contactless proximity switch which is integrated into the spring-loaded brake and which is rigidly connected to the stationary part of the spring-loaded brake. The respective switch cooperates with a reference point on the armature disk (3). The novelty of the invention consists in that the reference point is arranged on an adjustable lever/beam (9) on the armature disk (3), said lever/beam being rigidly connected to the armature disk (3) of the spring-loaded brake at one end of said lever/beam and being designed at the opposite end of said lever/beam so as to be adjustable (7/8) in the moving direction of the armature disk. The reference point is arranged on the lever/beam between the two ends of the lever/beam.
