Six-Wheel ATV Drivetrain with Segmented Bevel Gears
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing all-terrain vehicles with four wheels lack sufficient traction for certain utilitarian uses, necessitating a design that enhances traction capabilities.
Innovation Solution
A six-wheel all-terrain vehicle configuration with a third driveshaft, continuously variable transmission, and specific gear assemblies that connect the motor to the wheels, allowing for improved power distribution and traction through a straddle seat and multiple drive axles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a four-wheel configuration is used, then the vehicle structure is simple and easy to manufacture, but the traction is insufficient for demanding utilitarian applications
Solution Approach 1:
The vehicle is divided into multiple drive units with three separate driveshafts (first, second, and third driveshafts) that independently power different wheel groups. This segmentation allows each driveshaft to contribute to traction, resolving the contradiction by maintaining structural simplicity through modular segmentation while significantly improving overall traction capability for utilitarian applications
2Reliability
If a six-wheel configuration with multiple driveshafts is used, then the traction is enhanced for utilitarian applications, but the device complexity increases
Solution Approach 1:
Multiple driveshafts and gear assemblies are merged into a single integrated power transmission system originating from one motor. The first, second, and third driveshafts are combined with their respective gear assemblies to form a unified six-wheel drive system, which enhances traction while managing complexity through consolidation rather than separate independent systems
Solution Approach 2:
The motor and transmission system serve multiple functions by simultaneously powering all six wheels through the network of driveshafts and gear assemblies. This multi-functionality allows a single power source to provide enhanced traction across all wheels, resolving the contradiction by achieving complex traction capabilities through a universal power distribution system rather than multiple separate systems

AI summary
A vehicle has a frame, a motor, two front wheels, a first driveshaft operatively connected to the motor, and a first gear assembly operatively connected to the first driveshaft. The first gear assembly includes a first bevel gear operatively connected to the first driveshaft, a second bevel gear meshed with the first bevel gear, and a third bevel gear meshed with the second bevel gear. Two intermediate wheels are operatively connected to the second bevel gear. A second driveshaft is operatively connected to the third bevel gear. A second gear assembly is operatively connected to the second driveshaft. Two rear wheels are operatively connected to the second gear assembly.
