Vehicle Air Guide Path Structure for Steering Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle air guide path structures can reduce air resistance but often fail to improve steering stability issues such as wobbling or flapping during travel.
Innovation Solution
A vertically long air guide path forming member is provided along the outer edge of a vehicle's side surface at the rear of the wheel house, partitioned by a protruding member to form sections, which suctions air from the wheel house and exhausts it along the vehicle's side surface, incorporating a vertically long inclined surface to manage airflow and reduce vortex formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If air is efficiently exhausted from the wheel house to reduce air resistance, then air resistance decreases, but steering stability deteriorates due to wobbling or flapping
Solution Approach 1:
The air guide path is divided into multiple sections by partition members that extend in the vehicle width direction, creating separate flow channels. This segmentation allows different airflows to be managed independently, enabling efficient air exhaustion while controlling vortex formation to maintain steering stability
Solution Approach 2:
The partition members are positioned at specific locations within the air guide path to create localized flow control. By strategically placing partitions, the patent achieves efficient air exhaustion in certain regions while suppressing vortex generation in critical areas that would affect steering stability

AI summary
In a vehicle air guide path structure, a vertically long air guide path forming member is provided along an outer edge of a side surface portion of a vehicle body on a rear side of a wheel house. A vertically long air guide path is formed at the rear side of the wheel house. The vertically long air guide path suctions air from the wheel house and exhausts air along a side surface of the vehicle body. A partition member partitions the vertically long air guide path so as to form a plurality of sections in an upper-lower direction. A vertically long inclined surface is formed on the side surface portion of the vehicle body at a rear side of the vertically long air guide path. The partition member protrudes to a rear side from the vertically long air guide path.
