AUTOMATIC TRANSMISSION CHAIN. The automatic transmission chain is an important component of the vehicle drivetrain and is used in the design of certain types of automatic and continuously variable transmissions (CVT) to transmit torque between shafts and internal mechanisms. This component ensures reliable and smooth power transfer within the transmission, contributing to stable gearbox operation. The main function of the automatic transmission chain is to transmit rotational motion from one shaft to another inside the transmission assembly. Compared to gear drives, a chain drive allows more flexible torque transfer and can be used in compact transmission layouts while reducing noise and vibration levels. Structurally, the automatic transmission chain is a high‑strength metal chain consisting of specially shaped links designed to operate under significant loads and in conditions of continuous circulation of transmission fluid. The component is manufactured from high‑quality alloy steel and undergoes heat treatment to increase strength, wear resistance and durability. During operation, the transmission chain works inside the sealed transmission housing, is constantly lubricated by transmission oil and interacts with driving and driven sprockets. Proper condition of the automatic transmission chain ensures efficient torque transfer, smooth gear operation and reliable performance of the automatic transmission. The catalog includes automatic transmission chains designed for various passenger cars, SUVs and commercial vehicles.
