Leaning Vehicle Frame Layout for Flexible Rider Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Leaning vehicles lack design flexibility in the riding position of the driver and the layout of parts mounted on the vehicle body frame, limiting their customization and functionality.
Innovation Solution
A leaning vehicle design that includes a vehicle body frame with a main framework part extending linearly in the front-rear direction, supporting a leaning linkage mechanism and buffer devices, allowing the vehicle body frame, front wheels, and rear wheel to lean leftward or rightward, with a buffer device to absorb movement, enhancing design flexibility by positioning key components such as the leaning linkage mechanism and seat support further downward than the steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vehicle body frame uses a conventional layout structure, then the structural stability is maintained, but the design flexibility in riding position and part layout is limited
Solution Approach 1:
The vehicle body frame is divided into a main framework part and a sub-framework part. The main framework part provides structural stability, while the sub-framework part offers flexible mounting positions for the leaning linkage mechanism and other components, enabling customized layouts without compromising overall frame integrity
Solution Approach 2:
The patent introduces vertical positioning options by placing the leaning linkage mechanism either above or below the steps, adding a vertical dimension to the layout flexibility. This allows designers to optimize component placement without affecting the horizontal structural stability of the frame
2Ease of operation
If the leaning linkage mechanism is positioned higher for better accessibility, then ease of operation improves, but stability and handling may be compromised
Solution Approach 1:
The patent provides different vertical positioning options for the leaning linkage mechanism (above or below the steps) tailored to different vehicle types and usage scenarios. This local customization allows optimal balance between accessibility and stability for each specific application

AI summary
A leaning vehicle including a vehicle body frame having a main framework part, a seat, left and right steps, left and right front wheels, at least one rear wheel, a leaning linkage mechanism including left and right swing arms swingably supporting the left and right front wheels and connected to the vehicle body frame via left and right support parts, respectively, and a buffer device buffering movement of the left and right front wheels. The leaning vehicle leans the vehicle body frame leftward and rightward when turning left and right, respectively. The main framework part includes a main-framework-front portion that is located further forward than centers of the left and right steps, that is wider than a distance between the left and right support parts, and that supports the leaning linkage mechanism at a position further downward than at least a part of the left and right steps.
