NATO Supply Class 2520 is a classification within NATO Supply Group 25, which is dedicated to Vehicular Equipment Components. Specifically, Class 2520 focuses on Vehicular Power Transmission Components.

Vehicular Power Transmission Components refer to the various parts and systems that are responsible for transmitting power from the engine to the wheels of a vehicle. These components play a crucial role in ensuring the smooth operation and movement of the vehicle.

Some examples of Vehicular Power Transmission Components that fall under NATO Supply Class 2520 include:

1. Transmissions: These are mechanical devices that transmit power from the engine to the wheels, allowing the vehicle to change gears and transfer torque.

2. Transfer Cases: Transfer cases are used in four-wheel drive and all-wheel drive vehicles to distribute power between the front and rear wheels. They allow for smooth transitions between different driving modes.

3. Axles: Axles are shafts that connect the wheels to the vehicle's transmission or differential. They transmit power from the transmission to the wheels, allowing for rotation and movement.

4. Drive Shafts: Drive shafts are responsible for transmitting torque from the transmission to the wheels. They connect the transmission to the axles and allow for power transfer.

5. Differentials: Differentials are gear mechanisms that allow the wheels to rotate at different speeds while still receiving power from the transmission. They are essential for smooth turning and maneuvering of the vehicle.

These are just a few examples of the Vehicular Power Transmission Components that fall under NATO Supply Class 2520. The classification helps in organizing and categorizing these components for procurement and supply chain purposes within NATO.
