Hybrid All-Terrain Vehicle Layout for Compact Power and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
All terrain vehicles face challenges in maintaining sufficient power while being compact in size, leading to issues with weight distribution, stability, and limited mounting positions for internal components.
Innovation Solution
A hybrid electric all terrain vehicle design with a power motor connected to the front axle and an engine connected to the rear axle, along with a balanced weight distribution by positioning the power motor at the front, engine in the middle, and battery and controller at the rear, enhancing four-wheel drive capability and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the vehicle size is reduced to reduce weight and improve off-road performance, then the weight is reduced and off-road performance is improved, but the mounting position for internal parts becomes limited and weight distribution becomes uneven
Solution Approach 1:
The vehicle frame is divided into upper and lower main beam frames with multiple mounting positions. The power motor is mounted on the lower main beam frame at the front, the engine is mounted on the lower main beam frame in the middle, and the battery and controller are mounted on the rear, creating segmented weight distribution across different zones of the vehicle frame.
Solution Approach 2:
The patent utilizes the vertical dimension by mounting components on both the upper and lower main beam frames. The cushion is mounted on the upper main beam frame while the engine and power motor are mounted on the lower main beam frame, effectively using three-dimensional space to accommodate all internal parts even in a compact vehicle design.
2Weight of moving object
If the vehicle size is reduced to reduce weight and improve off-road performance, then the weight is reduced and off-road performance is improved, but the weight distribution becomes uneven and stability deteriorates
Solution Approach 1:
The patent employs asymmetric weight distribution strategy by positioning the power motor at the front, engine in the middle, and battery with controller at the rear on the lower main beam frame. This asymmetric arrangement creates a balanced weight distribution that enhances vehicle stability while maintaining compact dimensions.
Solution Approach 2:
The patent uses the cushion mounted on the upper main beam frame as a counterweight element. The cushion's position and weight help balance the overall vehicle weight distribution, compensating for the asymmetric placement of powertrain components and improving overall vehicle stability.
3Weight of moving object
If a smaller vehicle size is used, then weight is reduced and off-road performance is improved, but power performance becomes insufficient
Solution Approach 1:
The patent combines a power motor and an engine in a hybrid configuration. The power motor is drivingly connected to one of the front or rear axles, while the engine is drivingly connected to the other axle, creating a four-wheel drive system that maximizes power output from compact components.
Solution Approach 2:
The power motor serves multiple functions: it provides primary propulsion, acts as a generator during regenerative braking, and can function as an auxiliary power source. This multi-functionality allows the compact power motor to deliver power performance equivalent to or exceeding larger single-function engines.
