Three-Roller Running Gear Steering Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing running gears for transporting heavy loads often become unstable during transport, leading to uncontrolled rotation around a perpendicular axis, making handling difficult and unstable.
Innovation Solution
A running gear design featuring three rollers, where two rollers are rotatable relative to the carrier plate and one is fixed, allowing for steering while maintaining stability by aligning rotatable rollers perpendicular to the direction of travel and using a fixed roller to guide and stabilize the gear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If four rollers are arranged on the carrier plate to enable steering, then the running gear can be steered in any direction, but the running gear becomes unstable and rotates uncontrolled during transport
Solution Approach 1:
The roller system is segmented into three distinct rollers with different functions: two steerable rollers (5, 6) that can rotate about perpendicular axes for directional control, and one fixed roller (7) that maintains stable contact with the subsurface for transport stability. This segmentation allows each roller to perform its specific function without interfering with the others, resolving the contradiction between steering capability and transport stability
Solution Approach 2:
Different rollers are assigned different local qualities: the first and second rollers have rotatable mounting to enable steering, while the third roller has a fixed mounting to provide stability. This local differentiation of properties allows the system to simultaneously achieve both steering capability and transport stability by optimizing each component's characteristics for its specific role
2Ease of operation
If two rollers are made rotatable to improve steering, then handling is simplified, but the running gear may become unstable during transport
Solution Approach 1:
The roller arrangement employs asymmetric configuration where two rollers (5, 6) are mounted to rotate about perpendicular axes for steering, while the third roller (7) is fixed in a specific orientation. This asymmetric design creates a stable triangular support base during transport while maintaining steering capability through the rotatable rollers, resolving the contradiction between improved handling and transport reliability

AI summary
The present invention relates to a running gear having a carrier plate and a first roller, a second roller and a third roller, which are arranged on the carrier plate. Simplified handling and/or increased stability of the running gear is produced if the first roller can rotate about a first rolling axis running parallel to a plane of extent of the carrier plate and the second roller can rotate about a second rolling axis running parallel to the plane of extent and the third roller can rotate about a third rolling axis running parallel to the plane of extent. The invention further relates to an arrangement having at least two such running gears, wherein at least two such running gears are connected to each other.
