Common Automotive Timing Chain Types

The auto timing chain of the car is one of the valve trains that drive the engine, so the intake and exhaust valves of the engine are opened or closed at the appropriate time to ensure that the engine cylinder can inhale and exhaust normally; at the same time, the timing chain of the car engine Timing chains are more reliable and durable than traditional timing belts. Generally speaking, the timing chain of a car does not need to be replaced frequently, and its normal life span is between 300,000 and 500,000 kilometers.

In addition, the entire system of the timing chain is composed of gears, chains, tensioning devices, and other components, and the use of metal chains can also make it maintenance-free for life, which is almost the same as the life of the engine, thereby reducing the later use and maintenance costs of the engine. few.

At present, common timing chains are mainly divided into two types: sleeve roller chains and toothed chains; among them, the roller chain is affected by its innate structure, the rotation noise will be more obvious than the timing belt, and the transmission resistance and inertia will be correspondingly larger.
