Bearing Bracket Assembly for Multi-Car Vehicle Coupler Rods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing designs for multi-car vehicle coupler rods and connection systems require space in the underframe of the car, limiting design flexibility and increasing complexity.
Innovation Solution
The assembly relocates the connection portion of the bearing bracket forward, allowing space behind for assembly components, using a rear portion with support elements to connect the bracket to the car, and incorporates a pin and rubber elements for force transmission, with a rear plate that can be part of the car's structure, eliminating the need for protrusions into the underframe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the connection portion is placed in the underframe of the car, then the assembly can be connected to the car, but it requires space in the underframe limiting design flexibility
Solution Approach 1:
The connection portion is relocated from the underframe area to the front end of the coupler rod, changing the spatial arrangement from a rearward/underframe position to a forward/exterior position. This dimensional shift eliminates the need for underframe space while maintaining connection functionality.
Solution Approach 2:
The bearing bracket is divided into a connection portion and a rear portion, with the connection portion separated and positioned at the front end of the coupler rod. This segmentation allows the connection function to be independent of the underframe structure, freeing up space in the underframe area.
2Ease of manufacture
If the connection portion requires space in the underframe, then the assembly can be mounted, but it increases structural complexity
Solution Approach 1:
The connection portion is extracted from the underframe integration and repositioned to the front end of the coupler rod. This extraction simplifies the overall structure by eliminating the need for complex underframe modifications, holes, or recesses, while maintaining the mounting capability.
3Ease of operation
If the pin is allowed to swivel freely, then the coupler rod can rotate relative to the bracket, but the pin may contact the rear plate causing additional wear
Solution Approach 1:
The pin's movement is made dynamic and controlled rather than fully free. The hole in the coupler rod provides guided movement that allows necessary rotation while constraining the pin's path to prevent contact with the rear plate, reducing wear while maintaining operational flexibility.
Solution Approach 2:
The hole in the coupler rod acts as an intermediary element between the pin and the rear plate. It provides a controlled path for the pin's movement, allowing rotation capability while mediating to prevent direct contact between the pin and rear plate, thus reducing wear.

Function Achieved in This Case
This design enhances design flexibility by allowing closed surfaces on the car, reduces complexity, and effectively transmits forces without requiring large recesses or holes in the underframe, improving the integration of coupler rods and connection systems within multi-car vehicles.
