synchronous timing belt

In a CVT system, the transmission belt operates between two pulleys that can change diameter. As the engine generates power, the primary pulley expands and contracts, causing the belt to move up and down its sides. This movement adjusts the gear ratio according to the vehicle's speed and engine load, allowing for optimal engine performance and efficiency at all times. The belt's ability to flex and adapt is what makes the CVT smooth and responsive, eliminating the shift shock commonly experienced in traditional transmissions.

The serpentine belt, an essential component of modern vehicles, plays a critical role in the operation of various engine accessories. This single, continuous belt is designed to drive multiple peripheral devices, including the alternator, power steering pump, water pump, air conditioning compressor, and sometimes the coolant pump. Understanding the use and significance of the serpentine belt can help vehicle owners maintain their cars effectively and prevent costly repairs down the line.
