Vehicle Track Bogie Suspension for Traction and Vibration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Off-road vehicles equipped with track systems experience uneven load distribution and vibration when traveling on soft or uneven ground, leading to user discomfort and premature component failure.
Innovation Solution
A track system with an elastomeric track and a bogie design featuring movable joints and resilient elements to enhance traction and reduce vibrations, incorporating a frame, drive wheel, roller wheels, and a resilient member to allow rotational and translational movements of the roller wheels relative to the frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a track system is used to enhance traction on soft and uneven ground, then traction and floatation are improved, but vibration and uneven load distribution occur leading to user discomfort and component failure
Solution Approach 1:
The bogie is designed to be movable relative to the frame, allowing dynamic adjustment of the roller wheels' position. The movable joints enable the bogie to adapt to uneven ground conditions, while resilient elements provide shock absorption. This dynamic configuration allows the track system to maintain traction on soft ground while reducing vibrations and uneven loads on components.
2Ease of operation
If the bogie is made movable to reduce vibration, then ride quality is improved, but the device complexity increases
Solution Approach 1:
The bogie is divided into multiple segments connected by movable joints, allowing independent movement of each segment. This segmentation enables the bogie to conform to uneven terrain while distributing the complexity across multiple simple joints rather than requiring a single complex mechanism. The resilient elements are also distributed at different locations to provide localized shock absorption.

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 system improves traction and ride quality by evenly distributing load and reducing vibrations, enhancing the performance of off-road vehicles on soft and uneven terrain.
Implementation Method 1
a resilient element disposed between the bogie and the frame, configured to resiliently affect the movement of the axis of rotation of the given ones of the roller wheels relative to the frame

AI summary
A track system for traction of a vehicle (e.g., an agricultural vehicle) in which the track system is designed to enhance traction and/or ride quality (e.g., reduce vibrations), when travelling on a soft and/or uneven ground area (e.g., an agricultural field) and/or when roading, by providing an improved suspension functionality (e.g., with plural articulations and resilient effects).
