Working Vehicle Step Load Distribution via Split Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional working vehicles, such as agricultural tractors, face a problem where the step load is concentrated on specific members, leading to potential structural stress and reduced durability.
Innovation Solution
The vehicle design incorporates a step configuration where the upper side step part is attached to the floor and the lower side step part is attached to a fuel tank supporting bracket, distributing the load and reducing concentration on specific members, with additional gripping members attached to the upper side step part and rear wheel fender for secure entry and exit.

1Device complexity
If the step is attached to a single member, then the structure is simple, but the step load is concentrated on specific members
Solution Approach 1:
The step is divided into an upper side step part and a lower side step part, with each part attached to different supporting members. The upper side step part is attached to the floor while the lower side step part is attached to the fuel tank supporting bracket, thereby segmenting the load path and distributing step load to multiple members instead of concentrating it on a single member.
