Spring-Loaded Brake Assembly via Locking Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of electromagnetically actuable spring-applied brakes is complex due to their pre-assembled state requiring multiple parts to be aligned and fastened simultaneously, often necessitating additional holding elements that need to be removed during installation.
Innovation Solution
A securing element interacts with a fastening element to hold the brake together as a one-piece object until assembly is complete, allowing for easier handling and alignment, with the securing element exerting a clamping force to prevent displacement and enabling the brake to be transferred into a pre-assembled state where it can be securely fastened.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the brake is assembled in a pre-assembled state requiring multiple parts to be aligned and fastened simultaneously, then the brake can be securely fastened to the device, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The brake is pre-assembled as a complete unit at the factory before delivery, including all internal components, friction linings, and adjustments. This preliminary assembly action eliminates the need for complex on-site alignment and fastening operations, allowing the brake to be installed as a single module while maintaining secure fastening through the interaction between the locking element and fastening element.
2Stability of the object's composition
If additional holding elements such as bands are used to encircle the spring-applied brake during assembly, then the brake can be held together for transport, but these elements must be removed during installation adding to the complexity
Solution Approach 1:
The patent removes the need for additional holding elements like bands by integrating the locking function directly into the fastening element through the locking element. This extraction of the holding function from separate auxiliary elements and its integration into the fastening mechanism itself eliminates the need to install and subsequently remove bands during assembly, simplifying the installation process while maintaining assembly stability.
3Ease of operation
If the locking element is designed to interact with the fastening element to hold the brake together, then the brake can be handled as a single-piece object, but the locking element must overcome clamping force to be moved on the fastener
Solution Approach 1:
The locking element is designed with dynamic characteristics that allow it to slide freely on the fastening element during normal handling and installation operations. The clamping force is engineered to be sufficient to prevent unintentional displacement during operation but can be deliberately overcome during controlled installation. This dynamic design enables the brake to be handled as a single-piece object while maintaining secure locking when required.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach simplifies the assembly process by allowing the brake to be handled and secured as a single unit, reducing complexity and the need for additional holding elements, thereby streamlining the installation process while maintaining secure fastening.
Implementation Method 1
The coil generates a magnetic field that acts on a movable brake element. In brakes of the type in question, the brake is opened or released by the effect of the electrical field on the movable brake element.
Implementation Method 2
the force with which the brake element presses the rotor against the counter-braking element is generated by elastic elements. These can be, for example, compression springs, particularly helical compression springs.

AI summary
The invention relates to an electromagnetically actuated spring-loaded brake (1) comprising an electric coil (19) for actuating the spring-loaded brake (1), and a braking rotor (15) that can be connected to a shaft, the spring-loaded brake (1) having a braking element (14) to which a spring force is applied and which presses the braking rotor (15) against the mating braking element (10) in order to apply the spring-loaded brake (1). The spring-loaded brake (1) is kept together in a preassembled state by a securing element (16), in particular a clamping ring, which cooperates with a fastening element (17), in particular a screw, in order to fasten the spring-loaded brake (1) to a device, in particular to a drive system.
