Axle Fixation Molded Structure Lateral Force Binding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing axle connections for spring-loaded vehicle axles rely heavily on the tension strength of U-shaped brackets to manage lateral forces during driving, which is insufficient for practical operation, leading to potential misalignment and instability.
Innovation Solution
The axle connection incorporates a molded structure with an indentation on the axle body's partial circumference, featuring support surfaces and a flat contact surface that forms a channel-shaped handlebar mount, ensuring secure binding of the trailing arm and tension elements, preventing slipping and misalignment, and allowing for effective transmission of lateral forces without relying solely on tension element strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If tension elements are used to bind the axle body and trailing arm, then the parts are integrated in mutual contact, but the lateral forces during driving are insufficiently managed
Solution Approach 1:
The patent applies local quality by providing a molded structure with a specific form fit at the local position where the trailing arm contacts the axle body. This localized geometric feature (with support surfaces and contact surfaces) provides form-fit connection specifically for lateral force transmission, while the tension elements continue to provide overall binding. The molded structure's geometry is specifically adapted to the local requirement of lateral force management without changing the entire connection design.
2Stability of the object's composition
If the axle body and trailing arm are tightened against each other, then mutual contact is achieved, but the connection becomes dependent on tension element strength for lateral forces
Solution Approach 1:
The molded structure with its specific geometry (support surfaces and contact surfaces) enables the connection to serve itself by providing form-fit positioning and lateral force transmission capability inherent in the geometry. The structure automatically provides the necessary stability and lateral force management through its shape, reducing dependence on the tension elements' strength for these functions.
3Device complexity
If a simple crossing arrangement is used, then the structure is simple, but the tension elements can slip or be offset due to lateral forces
Solution Approach 1:
The molded structure is pre-formed with specific geometric features (support surfaces and contact surfaces) that preliminarily establish the correct positioning and prevent slipping before the tension elements are even tightened. The form-fit connection is built into the structure itself, providing preliminary action that prevents offset and maintains positioning accuracy throughout operation.

AI summary
The axle integration has a longitudinally extending axial body (1), which is provided with intersecting longitudinal links (2) on its upper or lower side. A traction element integrates these parts and runs to the axial body at the lateral side of the longitudinal links. The axial body is provided with a molded structure (13,26) in the integration area, which accommodates the longitudinal link and the traction element in form fit manner and binds locally the axial body in longitudinal direction (L) of the axial body.
