The Power of a Truck’s Transmission: Driving Every Journey

Anh Tuấn, a seasoned Hyundai 75S truck driver in Hanoi, vividly remembers the day he received his truck. He likens the transmission system to the vehicle’s “heart,” the crucial link channeling power from the engine to the wheels, enabling him to navigate everything from Hanoi’s bustling streets to challenging mountain passes. Understanding the transmission’s vital role, Anh Tuấn prioritizes regular maintenance at reputable garages in Tam Trinh and Hoang Mai districts, ensuring his truck’s “heart” remains strong and reliable on every journey.

What is a Truck’s Transmission System?

A truck’s transmission system, also known as the gearbox, is a complex mechanical system responsible for receiving power from the engine and transmitting it to the wheels, enabling the vehicle to move.

The Role of a Truck’s Transmission System

1. Torque Conversion: The transmission system can adjust the engine’s torque to suit driving conditions. For instance, when a loaded truck climbs the steep Thanh Tri Bridge, the transmission generates higher torque to provide sufficient power for the ascent.
2. Speed Variation: This system allows the truck to operate at various speeds, from slow city driving to high speeds on the Phap Van – Cau Gie Expressway.
3. Reverse Movement: The transmission enables the truck to move in reverse, facilitating parking and maneuvering in tight spaces, especially for long-haul trucks.
4. Neutral Gear: This system allows disengagement between the engine and wheels when necessary, such as at red lights or while parked.
