Brake Head Connector Block for Sealed Brake Particle Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing friction assemblies for railway braking systems face challenges in simplifying the assembly between the brake head, connector block, and connecting ring, which affects the efficient capture and removal of particles emitted during braking, leading to potential leaks and reduced suction effectiveness.
Innovation Solution
A friction assembly design where a connector block with a cavity connected to a suction device has holes aligned with secondary channels, allowing removably mounted connecting rings to be easily secured to the brake head, facilitating the reliable collection of particles from the friction plate during operation and simplifying maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connecting ring is mounted directly into the secondary channel of the brake head, then the particle capture effectiveness is improved, but the assembly complexity and difficulty increase
Solution Approach 1:
The patent introduces a connector block as an intermediary component between the brake head and the connecting ring. The connector block includes a cavity with an opening that aligns with the secondary channel, allowing the connecting ring to be mounted into the cavity rather than directly into the narrow secondary channel. This intermediary structure simplifies the assembly process while maintaining the particle capture function.
Solution Approach 2:
The patent divides the connection system into separate functional components: the brake head with secondary channel, the connector block with cavity and opening, and the connecting ring. This segmentation allows each component to be optimized independently and simplifies assembly by allowing the connecting ring to be installed into the larger cavity first, then the entire assembly to be connected to the brake head.
2Reliability
If the connecting ring is tightly sealed in the secondary channel, then the sealing effectiveness is improved, but the ease of maintenance and replacement deteriorates
Solution Approach 1:
The patent segments the connection system so that the connecting ring is mounted in the cavity of the connector block, which is separate from the brake head's secondary channel. The connector block has an opening that aligns with the secondary channel, creating a two-stage connection. This segmentation allows the connecting ring to be easily removed and replaced by accessing it through the opening, while still maintaining sealing effectiveness through the aligned channels.
Solution Approach 2:
The connecting ring is pre-mounted into the cavity of the connector block before the final assembly with the brake head. This preliminary mounting action allows the connecting ring to be easily installed and removed from the cavity, facilitating maintenance, while the subsequent alignment with the secondary channel ensures proper sealing during operation.
3Productivity
If the suction device is directly connected to the secondary channel, then the particle removal efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent introduces the connector block as an intermediary component that connects the suction device to the brake head's secondary channel. The connector block includes a cavity with an opening that aligns with the secondary channel, creating a simplified connection path for particle removal while reducing the overall device complexity by consolidating connection functions in a single component.
Solution Approach 2:
The connector block serves multiple functions: it provides a mounting cavity for the connecting ring, creates an aligned opening for particle flow, and serves as the connection interface for the suction device. This multi-functionality reduces the need for separate components, thereby reducing device complexity while maintaining particle removal efficiency.
