Trailer Maneuvering Device Holding Device Axle Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing maneuvering devices for trailers are heavy, costly, and require complex assembly due to non-standardized chassis geometries, necessitating a connecting rod for torque and bending moment support, which increases weight and assembly effort.
Innovation Solution
A holding device that attaches to the trailer's base frame and vehicle axle, eliminating the need for a connecting rod by distributing forces and moments through the vehicle axle, using a support device with a flange plate and mating flange to absorb loads and prevent deformation, allowing for easy mounting and dismantling without permanent connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a connecting rod is used to support torque and bending moment between the two drive sides, then sufficient torsional rigidity is achieved, but the overall weight and assembly effort increase
Solution Approach 1:
The patent extracts and eliminates the connecting rod from the system by redirecting the torque support function to the vehicle axle. The carrier is designed to be supported directly on the vehicle axle, which inherently provides the necessary torsional rigidity without requiring an additional connecting rod between drive sides
Solution Approach 2:
The vehicle axle is utilized for multiple functions: it serves both as the support for the carrier and as the structural element that provides torsional rigidity for the entire maneuvering device, eliminating the need for dedicated torque-supporting connecting rods
2Adaptability or versatility
If complex clamping mechanisms and adapter plates are used to accommodate different chassis geometries, then adaptability to various trailer types is achieved, but the assembly effort and costs increase
Solution Approach 1:
The mounting system is segmented into standardized interface elements (carrier support structure, clamping mechanism) that can be independently adjusted. This modular approach allows adaptation to different chassis geometries through simple repositioning rather than requiring complex custom adapter plates for each configuration
Solution Approach 2:
The clamping mechanism incorporates dynamic adjustment capabilities, allowing the mounting positions and orientations to be modified according to the specific chassis geometry. This enables the same standardized carrier to be adapted to various trailer types without increasing overall system complexity
3Stability of the object's composition
If the carrier is rigidly fixed to the base frame, then structural stability is achieved, but the ability to accommodate different chassis geometries is reduced
Solution Approach 1:
The mounting system transitions from a fixed rigid connection to a dynamically adjustable connection. The carrier support structure can be positioned and oriented according to the specific chassis geometry, providing both structural stability during operation and adaptability during installation across different trailer types
