📌6 Types of Vehicle Transmissions and Their Technical Characteristics 📌
This illustration shows six common types of vehicle transmissions, each with a different working principle and performance characteristics:
Manual Transmission (MT) – Uses a mechanical clutch and manual gear selection by the driver. It offers full control, simple construction, high mechanical efficiency, and relatively low maintenance cost.
Automatic Transmission (AT / Torque Converter) – Utilizes a torque converter and planetary gear sets. Gear changes are smooth and comfortable, ideal for heavy traffic, but with higher hydraulic power losses compared to manual systems.
CVT (Continuously Variable Transmission) – Employs pulleys and a belt or chain to provide continuously variable gear ratios. It delivers smooth acceleration and good fuel efficiency, though it is less suitable for high torque loads without reinforced design.
IMT (Intelligent Manual Transmission) – A manual gearbox without a clutch pedal; the clutch is operated by electronic actuators. The driver selects gears while the system automatically controls the clutch for improved comfort.
DCT (Dual Clutch Transmission) – Uses two separate clutches for odd and even gears. This enables extremely fast and efficient gear shifts, making it ideal for performance-oriented vehicles, though it is more complex and heat-sensitive.
🔩 AMT (Automated Manual Transmission) – A conventional manual transmission automated with clutch and gear-shift actuators. It is more affordable than AT or DCT systems, but gear changes may feel less smooth.
Each transmission type is designed to meet different priorities, ranging from efficiency and comfort to driving performance.
