Commercial Vehicle Axle Stiffening with Angle Profile
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern commercial vehicle manufacturers face the challenge of designing axles that meet varying requirements for off-road mobility and axle load, necessitating individual redesigns for different vehicle types, which is inefficient and lacks a standardized solution for torsional rigidity across all models.
Innovation Solution
A modular system is implemented using an angle profile that stiffens the axle body on its longitudinal side, allowing for standardized axle bodies to be reinforced according to individual requirements, applicable to both cast and forged axle beams, and suitable for steered, driven, and leading/trailing axles, regardless of vehicle size or intended use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual axle designs are created for different vehicle types to meet varying off-road mobility and axle load requirements, then the torsional rigidity and performance are optimized for each specific application, but the device complexity and development time increase due to multiple redesigns
Solution Approach 1:
The patent applies universality by designing a standardized axle body that can serve multiple vehicle types and applications. The modular angle profile stiffening system allows the same basic axle design to be adapted for different off-road mobility requirements and axle load specifications, eliminating the need for complete redesigns for each vehicle type while maintaining optimized performance characteristics.
Solution Approach 2:
The patent segments the axle into a standardized base component (axle body) and a configurable stiffening element (angle profile). This segmentation allows the angle profile to be independently adjusted or removed based on specific vehicle requirements, enabling customization without modifying the core axle body design and reducing overall development complexity.
2Productivity
If standardized axle bodies are used across all vehicle models, then production efficiency and manufacturing cost are improved, but the torsional rigidity cannot be optimized for specific off-road and heavy-duty applications
Solution Approach 1:
The patent applies preliminary action by pre-configuring the axle body with standardized mounting points and interfaces for the angle profile stiffening system. This preliminary preparation allows the angle profile to be easily installed or adjusted during assembly based on specific torsional rigidity requirements, maintaining production efficiency while enabling strength optimization for different applications.
Solution Approach 2:
The patent applies local quality by adding the angle profile stiffening system only in specific regions where enhanced torsional rigidity is required. The angle profile can be selectively positioned and dimensioned to provide localized reinforcement for off-road and heavy-duty applications without modifying the entire axle body, thus maintaining standardized production while achieving application-specific strength characteristics.

AI summary
The axle has a cast or forged axle (1), which is stiffened at a longitudinal side through an angle profile (2), which lies at two sides (7,8) of the axle. The angle profile with a side lies laminar at the axle. The angle profile is fastened in an area range of its ends to the axle. The angle profile stands perpendicular with respect to a road surface and is fastened to the axle. The angle profile is fastened in an area of a plate of the axle supporting vehicle suspension system.
