Independent Suspension Steering Linkage Without Rocker Arm Supports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing independent suspension systems in all-terrain cranes are burdened by rocker arm sleeves and supports, which increase weight, occupy significant space, complicate assembly, and elevate economic costs.
Innovation Solution
The system eliminates rocker arm sleeves and supports by incorporating a steering mechanism with a mid-position locking cylinder, power steering cylinders, and steering linkages, and modifies the connection between the suspension cylinder and frame to reduce weight and space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rocker arm sleeves and supports are used to fix the steering mechanism, then the steering function is achieved, but the overall weight increases and assembly complexity increases
Solution Approach 1:
The patent removes the rocker arm sleeves and supports from the steering mechanism structure. By extracting these unnecessary components, the design achieves weight reduction while maintaining the essential steering function through a simplified direct mounting approach of the steering rocker arm unit to the frame.
2Reliability
If rocker arm sleeves and supports are used to fix the steering mechanism, then the steering function is achieved, but the assembly process becomes more complex
Solution Approach 1:
The patent eliminates the complex multi-component mounting structure by removing rocker arm sleeves and supports. The steering rocker arm unit is directly mounted to the frame, significantly simplifying the assembly process while preserving the steering function.
3Stability of the object's composition
If traditional steering mechanism with rocker arm supports is used, then steering stability is maintained, but the space occupied is significant
Solution Approach 1:
The patent merges the functions of the steering rocker arm mounting directly to the frame, eliminating the need for separate rocker arm supports and sleeves. This consolidation reduces the mounting space while maintaining steering stability through the simplified structural arrangement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design reduces overall weight, simplifies assembly, allows for a more compact arrangement, and decreases economic costs while maintaining functionality.
Implementation Method 1
The function of the damping device is to absorb the energy of vertical vibration of the suspension and convert it into heat energy to be dissipated, so that the vibration can be rapidly attenuated
Implementation Method 2
The elastic element is mainly used for mitigating impacts, which mainly depends on the elastic deformation of the elastic element and the tire
