Three-Wheel Vehicle Frame with Swing Arm and Synchronizing Levers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicles with two wheels are prone to sideslip, drifting, and loss of balance during sharp turns or braking, while three or four wheelers lack dynamic movability and stability at lower speeds, posing safety risks.
Innovation Solution
A frame mechanism for vehicles with at least three wheels, incorporating a swing arm, shock absorbing assembly, and synchronizing levers to absorb and distribute impact forces evenly between the first wheels, maintaining proper positioning and balance, and featuring a brake disc and caliper to prevent relative movement and ensure stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two wheels are mounted on one axle in a conventional two wheeler, then the vehicle can move, but it tends to sideslip during sharp turns, drift during braking, and lose balance when started or moving slowly
Solution Approach 1:
The vehicle is segmented into multiple independent wheel assemblies (first wheel frame assembly with two first wheels, and second wheel frame assembly with second wheels). Each assembly can move and absorb shock independently through swing arms and shock absorbing assemblies, allowing the vehicle to maintain stability while improving controllability during turns and braking.
2Reliability
If three or four wheels are mounted on one axle in a conventional vehicle, then the vehicle is more stable at lower speed, but it lacks dynamic movability and cannot tilt while needed
Solution Approach 1:
The wheel frame assemblies are designed with swing arms that allow dynamic movement and tilting. The first wheel frame assembly can swing relative to the vehicle frame assembly, enabling the vehicle to tilt during turns for better dynamics and movability while maintaining stability through the shock absorbing assembly and synchronizing levers.
3Reliability
If a swing arm and shock absorbing assembly are added to distribute impact force, then the vehicle stability improves, but the device complexity increases
Solution Approach 1:
The swing arm and shock absorbing assembly are merged into an integrated unit that combines both functions. The shock absorbing assembly is connected to the swing arm, allowing impact force absorption and wheel position maintenance to occur through a unified mechanism rather than separate components, thereby reducing overall complexity while maintaining stability.

AI summary
A frame mechanism for a vehicle with at least three wheels includes wheel frame assemblies (12, 13) to support a vehicle frame assembly (11) . By a shock absorbing assembly (22), a swing arm (31), two synchronizing levers (4) and two linking shafts (5), when any kind of loading carried and external forces are applied to the vehicle, the wheels (71) can constantly remain on the ground surface with the same traction so as to minimize the risk of yaw, drift and unbalance upon a turn or braking of the vehicle. Also, a variety of uneven movements of the wheels (71) can be balanced and converted into a movement of the vehicle frame assembly (11) in an up-and-down direction. In case of the wheels (71) running off the ground, the wheels (71) can be kept in a proper position for retouching down with safety and comfort.
