Independent Rear Suspension Kit Isolating Wheel Inputs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Solid-axle suspension systems in rear-wheel drive vehicles compromise performance and handling as inputs from one rear wheel can affect the other, leading to uneven movement and loss of camber.
Innovation Solution
An independent rear suspension kit is provided, featuring mounting brackets, a cross-member, differential housing, upper and lower control arms, and coil-over shocks, which isolates the rear wheels, allowing independent movement and adjustment for improved handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a solid-axle suspension system is used, then the structure is simple and robust, but the handling performance deteriorates because inputs from one wheel affect the other wheel
Solution Approach 1:
The solid axle is divided into two separate independent suspension systems, with each wheel having its own control arms and mounting points. This segmentation allows each wheel to move independently without affecting the other, resolving the handling performance issue while maintaining reasonable structural complexity through modular components.
2Ease of manufacture
If a solid-axle suspension system is used, then the manufacturing cost is low, but the vehicle performance deteriorates due to uneven wheel movement
Solution Approach 1:
The suspension system is segmented into independent left and right sides, each with separate control arms and mounting brackets. This allows for simpler individual components that can be manufactured separately at lower cost, while the overall performance is improved through independent wheel movement capability.
Solution Approach 2:
The control arms and mounting brackets are designed as universal components that can be used on both the left and right sides of the vehicle. This multi-functionality reduces the total number of unique parts, maintaining ease of manufacture while achieving independent suspension performance.
3Device complexity
If a solid-axle suspension system is used, then the structural complexity is low, but the camber stability deteriorates when one wheel encounters irregularities
Solution Approach 1:
By segmenting the suspension into independent control arms for each wheel, the system allows each wheel to maintain its camber angle independently. When one wheel encounters an irregularity, the other wheel's camber remains stable, resolving the camber stability issue without excessive structural complexity.
Solution Approach 2:
The control arms are designed with pivot points that allow dynamic adjustment of wheel angle and camber as the suspension moves. This dynamic capability maintains camber stability during operation while keeping the overall structure relatively simple through efficient use of pivoting joints.
