The transmission parts of the timing system are divided into two types: timing chain and timing belt. Many people are concerned about which type of transmission is better.

Timing belts have been used in engines for a long time. The technology is mature, the cost is low, and the noise is low, but it needs regular inspection and maintenance. Generally, 50,000 to 100,000 kilometers need to be replaced. The timing chain has significant advantages such as compact structure, high transmission power, high reliability and wear resistance, and lifetime maintenance-free, but compared to traditional timing belts, its noise is generally slightly higher.

But nothing is absolute. With the advancement of technology, tooth-shaped mute chains are used on some cars, and the noise is even lower than that of timing belts. It is believed that the widespread use of this timing chain will bring more convenience to the majority of car users.

Toothed mute chain

Common timing chains are mainly divided into 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.

What we usually call the "silent chain" adopts a tooth-shaped structure design, which makes the teeth softer during transmission, has less impact, and runs more smoothly. In addition, there is no chain roller structure that produces noise, so it can perform at the noise level. The upper is better than the traditional timing belt.
