Torque is a crucial technical specification for trucks, especially for heavy-duty vehicles that frequently transport bulky goods. So, what is truck torque? This article will provide a detailed explanation of the concept, significance, calculation, and applications of torque in truck operation.
What is Torque? Definition and Explanation
Torque, also known as moment of force, is a physical quantity that represents the ability to cause an object to rotate around an axis. In the context of trucks, torque represents the rotational force of the engine acting on the crankshaft, which is then transmitted to the wheels to move the vehicle. The greater the truck torque specification, the stronger the rotational force, and the better the truck’s ability to carry heavy loads and climb slopes.

Peak Torque and Its Role in Truck Operation
Peak torque is the maximum torque value that a truck engine can produce at a specific engine speed (RPM). A higher truck torque specification indicates greater power for overcoming difficult terrains and carrying heavy loads. This specification is typically measured in Newton meters (Nm) or pound-feet (lb-ft).
Trucks need high torque for:
- Powerful start-up: High torque allows trucks to start and accelerate easily, especially when heavily loaded.
- Excellent hill climbing: Strong pulling force from high torque enables trucks to climb slopes effortlessly.
- Transporting heavy goods: High torque ensures trucks can transport heavy cargo efficiently.
Significance of Truck Torque Specs in Vehicle Selection
The truck torque specification is a vital factor to consider when choosing a truck. It directly affects the vehicle’s operational capability and performance. When comparing different truck models, it is essential to pay attention to both the peak torque and the engine speed at which the peak torque is achieved.

Torque Calculation Formula and Units of Measurement
Torque is calculated using the formula:
τ = F x r x sin(θ)
Where:
- τ: Torque
- F: Applied force
- r: Distance from the point of force application to the axis of rotation (lever arm)
- θ: Angle between the force vector and the lever arm
The units of measurement for torque are typically Newton meters (Nm) or pound-feet (lb-ft).
Relationship Between Torque and Horsepower
Torque and horsepower are two closely related technical specifications. Horsepower is the rate at which work is done, representing the ability to perform work in a unit of time. High torque combined with high engine RPM will generate high horsepower. However, in truck operation, torque is often considered more important than horsepower because it determines the ability to carry heavy loads and overcome challenging terrain.
Conclusion
The truck torque specification is a key factor determining the performance and operational capability of a truck. Understanding torque will help you choose the right truck for your needs. For more detailed advice on truck models and technical specifications, please contact Xe Tải Mỹ Đình.
