Utility Vehicle Powertrain Mount Brackets for Vibration Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing utility vehicles face challenges in efficiently supporting the engine and transmission components, particularly in off-road conditions, due to the complex arrangement of the power transmission system which can lead to instability and inefficiencies.
Innovation Solution
The utility vehicle incorporates a vehicle body frame that supports the engine and transmission components using mount brackets, including a first and second mount bracket and a rear mount, which are elastically connected to the vehicle body frame via rubber bushes, providing stable support for the engine, transmission, and related components like the front wheel propeller shaft and air conditioner compressor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the engine and transmission are mounted directly to the vehicle body frame using rigid connections, then the structural strength and power transmission efficiency are improved, but the vehicle stability and vibration resistance deteriorate
Solution Approach 1:
The patent introduces mount brackets as intermediary components between the engine/transmission and the vehicle body frame. These mount brackets serve as mediators that decouple the rigid connection, allowing the power transmission system to be securely mounted while isolating vibrations from the vehicle body, thus maintaining both structural strength and vehicle stability
2Power
If the engine and transmission are mounted using rigid connections, then the power transmission efficiency is improved, but the vibration and instability increase
Solution Approach 1:
The mount brackets act as intermediary elements that facilitate power transmission while filtering out harmful vibrations. The brackets are designed to transmit torque and power efficiently from the engine and transmission to the vehicle frame, while their mounting configuration absorbs and isolates vibration, preventing it from propagating through the vehicle body
3Adaptability or versatility
If a complex arrangement of power transmission components is used, then the functionality and adaptability are improved, but the system stability and reliability deteriorate
Solution Approach 1:
The patent segments the power transmission system into modular components (engine, transmission, mount brackets) that are independently mounted to the vehicle frame. This segmentation allows each component to be optimized for its specific function while the overall system maintains stability through the standardized mounting interface provided by the mount brackets, reducing the negative effects of complexity
