Solution Overview
Problem
Off-road RVs are prone to distortion damage and safety risks when passing through bumpy road sections at high speeds due to excessive torque, which causes stress on the vehicle body and rear box structure.
Innovation Solution
A self-balancing device comprising an auxiliary beam body, front and rear triangular balance beam bodies, and an axle-holding device with hard and soft limit structures to limit swing angles and buffer inertia and gravity, ensuring stability and balance during bumpy conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the RV passes through bumpy road sections at high speed, then the driving efficiency is improved, but the vehicle body and rear box structure are prone to distortion damage and safety risks due to excessive torque
Solution Approach 1:
The patent applies beforehand cushioning by installing a self-balancing device with buffer structures before the RV encounters bumpy roads. The device includes front and rear balance beam bodies with triangular structures that can elastically deform to absorb shock, and an axle-holding device with soft limit structures that buffer the impact between the box body and chassis girder, preventing distortion damage before it occurs
Solution Approach 2:
The patent uses intermediary elements including the balance beam bodies that act as mediators between the box body and the road shocks, and the soft limit structure that mediates the force transmission between the axle-holding device and the chassis, reducing the direct impact on the vehicle body and rear box structure
2Device complexity
If traditional box fixing method is used, then the structure is simple, but the instantaneous pressure on one side reaches 17 tons causing distortion damage to the vehicle body
Solution Approach 1:
The patent applies segmentation by dividing the fixing structure into multiple components: auxiliary beam body, front triangular balance beam body, rear triangular balance beam body, and axle-holding device. This segmented structure distributes the 17-ton instantaneous pressure across multiple connection points and structural elements, preventing concentration of stress that would cause distortion damage
Solution Approach 2:
The patent introduces dynamic elements including the balance beam bodies with hard limit structures that allow controlled movement, and the soft limit structure that provides elastic deformation capability. These dynamic features enable the structure to adapt to and absorb high instantaneous pressures without rigid failure, maintaining strength under extreme loading conditions
