Electric Power Steering Motor Vertical Overlap with Battery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
All-terrain vehicles face a challenge in maintaining a compact vehicle width while achieving a long vertical wheel stroke, as existing designs that mount electric power steering units can restrict wheel travel due to the placement of electric motors and batteries.
Innovation Solution
The electric motor of the power steering unit is positioned to overlap vertically with the battery, which is placed above the front wheels, allowing for a compact vehicle width without impeding the vertical wheel stroke, and the front wheels do not need to be positioned outward to maintain this stroke.

If the electric power steering unit is mounted with the electric motor positioned to overlap the battery in the vertical direction, then the vehicle width remains compact, but the vertical wheel stroke may be restricted
Solution Approach 1:
The electric motor of the power steering unit is positioned to overlap the battery in the vertical dimension rather than horizontally. This dimensional reorganization allows both components to coexist within the same vertical space above the front wheels, achieving a compact vehicle width while preserving adequate vertical wheel stroke for off-road performance
