Bogie Brake Clamp Linkage for Automatic Gauge Change Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current track changing operations for rail trains are inefficient due to the need for manual adjustment of the vehicle wheel braking clamp, which increases operator workload and reduces the efficiency of gauge changes.
Innovation Solution
A bogie design that includes a braking hanger, a hanger slider, and a transmission member, where the hanger slider is connected to the braking hanger and movable along the transverse direction, and the transmission member drives the vehicle wheel braking clamp to automatically move to a position corresponding to the vehicle wheel, eliminating the need for manual adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of the vehicle wheel braking clamp is used, then the braking clamp can be positioned on the bogie, but the operator workload increases and track changing efficiency decreases
Solution Approach 1:
The braking clamp automatically follows the vehicle wheel movement through the transmission member mechanism. When the vehicle wheel moves along the gauge direction, it directly drives the transmission member, which in turn moves the braking clamp to the corresponding position without requiring operator intervention. The system serves itself by using the vehicle wheel's movement to automatically position the braking clamp.
Solution Approach 2:
The transmission member acts as an intermediary mechanism between the vehicle wheel and the braking clamp. It converts the vehicle wheel's movement into corresponding movement of the braking clamp, enabling automatic positioning. The hanger slider serves as another intermediary that guides and constrains the movement of the braking clamp along the bogie framework.
2Reliability
If the vehicle wheel braking clamp is fixed on the bogie through a pin, then the braking clamp can be locked in position, but the adjustment process becomes cumbersome and time-consuming
Solution Approach 1:
The braking clamp system transitions from a static fixed position (requiring pin insertion/removal) to a dynamic automatic following position. The transmission member enables the braking clamp to dynamically adjust its position along with the vehicle wheel movement, eliminating the need for manual pin operations while maintaining stable positioning through the mechanical coupling of the transmission mechanism.
3Adaptability or versatility
If manual disassembly and reinstallation of the pin is required for braking clamp adjustment, then the braking clamp can be repositioned, but the operation complexity increases
Solution Approach 1:
The manual pin operation is completely extracted and removed from the system. Instead of using a pin that requires disassembly and reinstallation, the patent employs a transmission member mechanism that automatically couples the braking clamp to the vehicle wheel movement, eliminating the pin entirely and simplifying the operation to automatic following action.
