Automotive transmission belts are a crucial component of a vehicle's powertrain system. They are responsible for transferring power from the engine to the wheels, enabling the vehicle to move forward or backward. But what exactly are these belts, and how do they work?
To start with, transmission belts are flexible, reinforced bands that run around pulleys or wheels. They are made of various materials, including rubber, neoprene, and Kevlar, among others, depending on the application and the required strength. The belts are designed to transmit power and torque from the engine to the transmission, which then sends the power to the wheels.
There are two main types of automotive transmission belts: V-belts and serpentine belts. V-belts are named after their V-shaped cross-section and are primarily used in older vehicles. Serpentine belts, on the other hand, are flat and wider and are used in most modern vehicles.
The operation of the belts is straightforward. As the engine runs, it turns a pulley that's connected to the transmission. The belt then runs around this pulley, and the rotation of the pulley pulls the belt along, causing it to rotate as well. The belt's rotation causes another pulley connected to the wheels to turn, which ultimately transfers the power to the wheels, propelling the vehicle forward.
However, transmission belts are subject to wear and tear over time, and they need to be replaced periodically. Factors such as heat, humidity, and exposure to oil can cause the belts to crack or deteriorate. When this happens, the belt may slip, resulting in a loss of power transmission or even a complete failure. To avoid such problems, it's essential to inspect the belts regularly and replace them when necessary. The replacement interval varies depending on the make and model of the vehicle and the type of belt used. 
In conclusion, automotive transmission belts play a vital role in the functioning of a vehicle's powertrain system. They transmit power from the engine to the wheels and allow the vehicle to move. Understanding how they work and maintaining them properly is crucial to ensuring your vehicle runs smoothly and reliably.

Timing belt: R(MR), Y(MY), RU, YU, ZAS, ZBS, ZA ZB, ZD, ZR, FS, RHD, RHX, RPP, RHDS, YS&lt
The main material of the belt body is high-quality synthetic neoprene (CR) or hydrogenated nitrile rubber (HNBR), both imported from Japan, with a variety of auxiliary materials for different purposes; the skeleton material is high-quality glass fiber cord imported from Japan; The toothed surface is protected by nyon 66 high-stretch cloth and is made strictly in accordance with technical specifications. It has the characteristics of neat appearance, full tooth profile, long service life and low noise.
Chloroprene rubber can be used for a long time in a working environment of 110°C and below; it has good aging resistance (especially ozone resistance); good chemical stability: in addition to strong oxidizing acids, it is resistant to general chemicals; it is resistant to fire and water Good performance. 
Hydrogenated nitrile rubber has extremely low oil swelling resistance, excellent oil resistance, good durability, and its dynamic wear resistance is better than chloroprene rubber, can reduce noise, effectively extend product life, and is the first choice for medium and high-end automobiles Transmission belt. The timing belt made of hydrogenated nitrile rubber can work at -40℃~+150℃. Its durability is increased by more than 1.5 times, the bandwidth is reduced by 20%, and the heat resistance is increased by 10°C. Therefore, in terms of fatigue life and water resistance, it is better than timing belts made of chloroprene rubber and chlorosulfonated polyethylene.
