Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steering test devices lack the accuracy in simulating the kinematics of a vehicle's steering system, particularly in the transverse and vertical directions, which affects the precision of stress testing on components like steering gears and bearings.
Innovation Solution
A steering test stand with a base plate extending in longitudinal and transverse directions, featuring rotatable control arms and wheel carriers connected via longitudinal axes, and driven by deflection levers to simulate precise kinematics in both directions, allowing for adjustable components to match various chassis configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If simulation is performed in both transverse and vertical directions using existing devices, then kinematic simulation capability is improved, but accuracy of axis kinematics simulation deteriorates
Solution Approach 1:
The control arm is divided into multiple segments with individual adjustment capabilities. Each segment can be independently positioned to achieve precise kinematic simulation in both transverse and vertical directions, resolving the contradiction between comprehensive simulation capability and simulation accuracy.
Solution Approach 2:
The device incorporates adjustable control arms that can dynamically adapt their position and orientation. This dynamic adjustability allows the system to maintain high simulation accuracy across different operating conditions while preserving full kinematic simulation capability in multiple directions.
2Adaptability or versatility
If multiple replacement control arms with adjustable distances are used, then manufacturing adaptability to different chassis is improved, but device complexity increases
Solution Approach 1:
The control arms are designed with universal adjustment mechanisms that allow a single component design to serve multiple chassis configurations. By incorporating adjustable length and angle capabilities, the same control arm structure can adapt to different vehicle platforms, reducing the need for multiple specialized components while maintaining high adaptability.
