Rail Brake Pad Holder Latch for Faster, Reliable Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing brake lining mounting systems for rail vehicles are not simple and reliable enough for replacement, and the tools used for releasing and locking the locking latch are also not user-friendly for efficient handling.
Innovation Solution
A brake lining mounting system with a pivotable locking latch and a specialized tool that includes a lever handle, actuating journal, guide element, and pivoting axle, allowing for ergonomic and reliable brake lining replacement by ensuring the tool can only be removed when the locking latch is locked, thus keeping hands free for replacement and preventing accidental release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking latch is used to secure the brake lining in the guide channel, then the brake lining is reliably locked in position, but the replacement process becomes more complex and time-consuming
Solution Approach 1:
The locking latch is designed as a pivotable component that can dynamically switch between a locking position (protruding into the guide channel to secure the brake lining) and a release position (retracted from the guide channel to allow removal). This dynamic mechanism enables quick replacement while maintaining secure locking during operation.
Solution Approach 2:
The brake lining is pre-assembled with the locking latch in a ready-to-install configuration. The guide web of the brake lining is pre-adapted to engage with the locking latch mechanism, allowing for rapid installation by simply inserting the pre-assembled unit into the guide channel without requiring complex field assembly procedures.
2Ease of operation
If a tool is provided for releasing and locking the locking latch, then the operation is simplified and made more reliable, but the device complexity increases
Solution Approach 1:
The tool is designed to engage directly with the locking latch mechanism, which has self-aligning features such as the guide web and locking latch geometry that automatically guide the tool into the correct position. The tool itself performs both releasing and locking functions through a single pivoting motion, eliminating the need for separate tools or complex操作流程.
Solution Approach 2:
The same tool is used for both releasing and locking the braking lining, performing multiple functions with a single device. The tool can engage the locking latch in either direction to either release or secure the brake lining, reducing the number of different tools needed and simplifying the overall system.

AI summary
A brake pad holder for a rail vehicle includes a pad holder and a brake pad held on the pad holder in a locked manner. The pad holder includes a guide channel extending in the longitudinal direction of the pad holder, in which the brake pad can be movably held, wherein, in order to lock the brake pad in the longitudinal direction of the pad holder, a locking latch pivotably held on the pad holder, which protrudes into the guide channel in a locking position in which the brake pad is fixed in a functional position, and is removed from the guide channel in a release position.
