Motorcycle transmission mechanism is mainly divided into chain drive, belt drive, shaft drive three kinds, of which the chain drive is the most widely used, of course, because it has a lot of advantages (small power loss, high tensile strength, suitable for high-speed driving, suitable for modification, relatively low cost), of course, it also has shortcomings (need regular maintenance, wear to replace, etc.). Today, let's talk about the knowledge of the chain, in-depth to the chain construction, installation methods, use and maintenance of common sense......

1, the importance of maintaining the chain;

The chain is an integral part of the transmission system. The chain is more outstanding in the efficiency of power transmission than the belt, the loss of kinetic energy is less, and the power generated by the engine is more completely transmitted to the rear wheel. However, because the chain of the truck is mostly exposed design, long-term contact with the dust or gravel in the air will abrasion the structure or surface of the chain, so the maintenance of the chain can not be neglected. Regular maintenance chain can not only extend the service life, but also maintain the transmission efficiency of power, so that you can enjoy the fun of riding more safely and comfortably.

2, the basic structure of the chain analysis;

In simple terms, we can think of a chain as a joint structure of a steel bullet model, consisting of interlocking chains, bushings and rollers, with pins passing through the middle to connect, giving the chain a single vector of mobility. This is the chain structure of our car, and then through other components affect the power transmission of the chain, the smoothness of operation, etc., the precision of the chain has a crucial impact on the efficiency and even safety of the vehicle.

There are two kinds of motorcycle chain, that is, the ordinary chain and the oil seal chain, the ordinary chain is generally used on the small-displacement model, the price is low, the cost is low, the transmission efficiency is better, but the life is relatively short, and it is easy to stretch, hundreds of kilometers need to adjust the tightness.

The oil seal chain is also known as the competitive chain, in fact, there is an oil seal in the middle of the inner and outer chain, and the oil seal is filled with grease, which plays the role of lubricating the chain roller and bushing, avoiding wear between the two, and thus extending the service life of the chain.

3. Does the oil seal chain also need maintenance?

Some riders think that since there is oil in the oil seal chain, there is no need to maintain it. In fact, the frequency of oil seal chain maintenance and non-oil seal chain is similar, the difference is that the life of the oil seal chain under regular maintenance will be much more than that of the non-oil seal chain, so the oil seal chain should pay more attention to maintenance! No matter what kind of chain, after driving in rainy days and mud, it will be more or less stained with sediment foreign bodies. Regular cleaning of mud and dirt, the chain can avoid foreign body wear, rust, oil seal damage, resistance, stuck and other problems, so that the chain can maintain smooth operation, full power transmission and ensure the best state of its service life.

4, the chain maintenance cycle;

The first maintenance time of the chain is about 500 kilometers, and the chain oil can be used for maintenance. At the same time, when racing, high-speed driving, rain riding and chain noise, it can also be maintained. Then, at 1000 km (or two lubricates), a cleaner is used to do a more comprehensive cleaning, keeping the surface of the chain clean and shaving the small debris stuck in the chain, helping the chain run more smoothly, reducing noise and maintaining transmission efficiency and service life.

5, chain cleaning;

In the chain cleaning, be sure to pay attention to the damage to the oil seal is very important! If you buy cleaners online, try to buy branded products. In addition to the basic functions of deep penetration, strong decontamination, no damage to the oil seal and metal, a good cleaning agent should also be able to combine rust prevention, lubrication and activation of the oil seal. If you want to keep it simple, mix your household dish soap with some hot water and clean with a chain brush or toothbrush.

6, the choice of chain oil;

Common chain oil is divided into three types, which are wet, dry and wax. Generally for anti-rejection, dry or wax chain oil is used, which has good adhesion, but its penetration efficiency and lubrication are often insufficient or have strong volatile harmful gas pollution. The penetration and lubrication efficiency are the most important functions of chain oil. Of course, the ordinary chain is sprayed regularly with anti-rust lubricant.
