ABSTRACT
The design of the dry dual-clutch transmission (DCT) for the 2025 Volkswagen Magotan aims
to improve vehicle power performance, fuel economy, and driving comfort, aligning with the
automotive industry's shift toward high efficiency, lightweight, and intelligent systems. As a
technology that combines the advantages of both manual and automatic transmissions, DCTs offer
high transmission efficiency, fast gear shifting, and a compact structure, making them widely used
in mid-to-high-end vehicles. This project, based on the DQ200 dry DCT architecture, includes the
overall layout design, dual-clutch mechanism configuration, gear transmission system design,
gearshift actuator optimization, and lightweight housing design. Key components are analyzed in
terms of force, durability, and thermal performance. Additionally, gear shift smoothness,
transmission efficiency, and cooling performance are evaluated through simulation. This design
enhances overall performance and reliability while offering a practical reference for the application
of cost-effective DCTs in mid-size passenger vehicles. It achieves a more compact structure,
reduced weight, and faster response, demonstrating technical value and engineering applicability.
