Solution Overview
Problem
Existing vehicle propulsion systems face inefficiencies in power distribution and propulsion modes, particularly in hybrid vehicles, where direct current and alternating current conversion is necessary, and there is a need for flexible power sources to enhance traction and propulsion under varying conditions.
Innovation Solution
A vehicle generator module with a rotor and stator arrangement, a clutch for connecting the combustion engine to the axle assembly, and a transmission for selective power distribution, combined with a battery and electric motor system, allowing for both direct and alternating current conversion and enabling all-wheel-drive or four-wheel-drive modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hybrid propulsion system with both combustion engine and electric motor is used, then power flexibility and traction capability are improved, but system complexity increases due to multiple power sources and conversion requirements
Solution Approach 1:
The propulsion system is segmented into two independent drive trains: a combustion engine drive train with generator module and clutch, and an electric motor drive train with battery and inverter. This segmentation allows each subsystem to operate independently, simplifying control logic while maintaining power flexibility through selective engagement of either system or both simultaneously.
Solution Approach 2:
The combustion engine serves multiple functions: it can directly drive the front axle assembly through the clutch for mechanical propulsion, or it can drive the generator to produce electrical power that charges the battery or powers the electric motor. This multi-functionality reduces the need for separate dedicated components for each function.
2Use of energy by moving object
If direct current conversion is implemented in the hybrid system, then power distribution efficiency is improved, but additional conversion components and control systems are required
Solution Approach 1:
The system replaces traditional mechanical power transmission with electrical power conversion and transmission. The generator converts mechanical energy from the combustion engine into electrical energy, which can then be efficiently distributed to the battery or electric motor with minimal loss, eliminating the need for complex mechanical gear systems and direct mechanical coupling between power sources.
3Ease of operation
If a transmission is added between the clutch and front axle assembly, then power distribution control is improved, but device complexity and space requirements increase
Solution Approach 1:
The transmission system is designed as a dynamic, adaptive system that can change its operational state based on real-time conditions. The clutch and transmission work together to dynamically adjust power flow, allowing the system to switch between different drive modes (combustion-only, electric-only, or hybrid) and to control power distribution to the front axles according to driving conditions, terrain, and power availability.
4Volume of moving object
If the combustion engine is arranged transverse to the driving direction, then space utilization is improved, but mechanical connection to the axle assembly becomes more complex
Solution Approach 1:
The clutch assembly serves as an intermediary component that simplifies the mechanical connection between the transverse combustion engine and the longitudinal axle assembly. It provides a compact interface that converts the transverse engine output into longitudinal power transmission to the axles, eliminating the need for complex transverse-to-longitudinal gear conversions while maintaining efficient power transfer.
