Bogie Brake Clamp Self-Positioning for Rail Gauge Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current track changing operations for rail trains are inefficient due to the cumbersome manual adjustment of vehicle wheel braking clamps, which requires disassembly and reassembly of the braking clamp to match new gauge settings, leading to low operational efficiency and increased operator workload.
Innovation Solution
A bogie design that includes a braking hanger, hanger slider, and transmission member, where the hanger slider is connected to the braking hanger and movable along the transverse direction, driven by a thrust from the vehicle wheel, allowing the vehicle wheel braking clamp to automatically adjust its position to match the wheel, eliminating the need for manual adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of the braking clamp is performed during track changing, then the braking clamp can be positioned to match the new gauge, but the operation process becomes cumbersome and efficiency decreases
Solution Approach 1:
The braking clamp automatically positions itself to match the vehicle wheel position through the transmission member mechanism. The system uses the wheel pair's own position as a reference, and the transmission member converts wheel position into corresponding braking clamp position automatically, eliminating the need for manual adjustment operations.
Solution Approach 2:
The transmission member acts as an intermediary mechanism between the wheel pair and the braking clamp. It receives positional information from the wheel pair and automatically translates it into the appropriate braking clamp position, serving as a mechanical mediator that eliminates manual intervention.
2Stability of the object's composition
If the braking clamp is fixed on the bogie through a pin, then the braking clamp remains stable, but manual disassembly and reassembly is required during track changing
Solution Approach 1:
The braking clamp transitions from a static fixed position to a dynamic adjustable position. The transmission member enables the braking clamp to move along with the wheel pair's position changes, transforming the system from a static pinned connection to a dynamic mechanically-linked system that automatically adapts to gauge changes.
3Manufacturing precision
If manual adjustment of the braking clamp position is performed, then the braking clamp corresponds to the adjusted vehicle wheels, but operator workload increases
Solution Approach 1:
The system performs self-positioning of the braking clamp based on the wheel pair's position. The transmission member automatically converts wheel position into the corresponding braking clamp position, making the system self-sufficient and eliminating the need for operator intervention in positioning tasks.

AI summary
A bogie and a rail vehicle, wherein the bogie includes: a framework, a wheel pair connected to the framework, a braking hanger fixed to the framework, a hanger slider used for fixedly connecting to a vehicle wheel braking clamp, and a transmission member; the hanger slider is connected to the braking hanger, and the transmission member is connected to the hanger slider; a first end of the transmission member extends to a side surface of a vehicle wheel in the wheel pair, and the transmission member is used to drive the hanger slider to move along the lateral direction with respect to the braking hanger when the first end is subjected to a thrust applied in the lateral direction by the vehicle wheel, so that the vehicle wheel braking clamp moves to a position corresponding to the vehicle wheel.
