Linear Suspension Spindle Carrier for Work Vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suspension systems in work vehicles, such as agricultural tractors, alter the wheel position relative to the ground, reducing uniform tire contact and affecting handling and steering, especially when traversing uneven surfaces.
Innovation Solution
An independent linear suspension system that includes a spindle carrier with pins blocking rotation while allowing vertical movement, coupled with damping cylinders to enhance ride quality and reduce wear on vehicle components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional suspension systems are used to dampen vibrations, then ride quality is improved, but wheel position relative to ground changes reducing uniform tire contact
Solution Approach 1:
The suspension system employs a dynamically adjustable mechanism that allows the wheel assembly to move vertically relative to the chassis while maintaining controlled positioning. The spindle carrier moves along the pin to accommodate vertical displacement, and the damping cylinder dynamically adjusts to maintain optimal tire contact with the ground surface, resolving the contradiction between ride comfort and contact uniformity.
Solution Approach 2:
The system changes the positional parameters of the wheel assembly by allowing vertical movement of the spindle carrier along the pin while constraining rotational movement. This parameter change enables the wheel to adapt its vertical position to maintain uniform ground contact while absorbing vibrations, thus improving both ride quality and contact reliability.
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
The independent linear suspension system maintains uniform tire contact, improves handling and steering, and reduces wear on vehicle components by allowing vertical wheel movement without rotation, thereby enhancing ride quality and operational efficiency.
Implementation Method 1
suspension systems that dampen vibrations caused by uneven surfaces over which the work vehicle travels
Implementation Method 2
The first pin and the second pin block rotation of the spindle carrier. The spindle carrier moves linearly along the first pin and the second pin.
