Coaxial Stabilizer Shock Absorber Connection Suppressing Rocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suspension structures experience rocking of the shock absorber due to different forces received from the wheel in the roll direction and axial direction, which affects the stability and comfort of vehicles.
Innovation Solution
The lower end portion of the shock absorber and the wheel side end portion of the stabilizer are made coaxial, with the stabilizer's reactive force acting as a bending moment on the shock absorber, suppressing rocking and improving stability by connecting the stabilizer's end portion to the lower end of the shock absorber and using a suspension arm with supporting plates that provide increased rigidity and elastic support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the stabilizer and shock absorber are connected at non-coaxial points, then the suspension structure can be simpler to manufacture, but the shock absorber experiences rocking motion reducing stability
Solution Approach 1:
The patent applies asymmetry by making the connection between the stabilizer and shock absorber coaxial, creating a symmetric alignment along the axial line. This coaxial connection point arrangement eliminates the rocking motion of the shock absorber that would occur with asymmetric, non-coaxial connections, thereby improving stability while maintaining manufacturing simplicity.
2Stability of the object's composition
If the stabilizer reactive force acts as a bending moment on the shock absorber, then rocking is suppressed, but the structural complexity increases
Solution Approach 1:
The patent creates an equipotential condition by aligning the stabilizer connection point with the shock absorber's axial line. This coaxial arrangement ensures that the reactive force from the stabilizer acts directly along the same line as the shock absorber's primary force vector, converting what would be a destabilizing bending moment into a beneficial stabilizing force that suppresses rocking motion without adding structural complexity.
