Ưu và nhược điểm của XÍCH, DÂY CUROA và TRỤC CÁC ĐĂNG | Đường 2 Chiều.

Hello everyone, welcome back to Hai Trieu I'm Thao Anh I'm sorry because the quality of today's video is not very good because we are all at home I only have an iPhone As we all know, Hanoi is in a social distancing period so we can't go out to film But it's okay, we still have a lot to talk about the car Today I want to talk about something a part of our car It is also important but actually few people pay attention to that is the transmission part So what is the transmission part? As we know, when the engine is on, the engine is spinning we have to have something to transfer the power from the engine to the rear wheel so the car can run, right? At the moment, we have 3 main options The first is the chain The second is the belt, also called the Quora and the third is the crankshaft The chain is the most common type It appears in both small cars and large cars As for the belt and the crankshaft it often appears in larger, bigger cars Of course, there is a reason for that and today we will find out the advantages and disadvantages of each type of transmission Let's start! First, I want to talk about the belt transmission or the Quora chain This is the most ancient type of transmission among these 3 types It has appeared in some documents of the Han dynasty which is before the Qing dynasty and later it was also used to transmit water However, the belt or the Quora chain at that time, the material was very different It was not as good as it is now A proof is that in the 20th century the belt was made of leather and it had a lot of problems It was slipped, it was broken, it was broken It was not effective at all so it was almost completely destroyed by the Chinese and the Chinese at that time Now the material of the belt and the Quora chain is much better Now it is made of composite material It feels a bit like rubber However, it is very hard and now there are some types that are hard enough Some good-quality Quora chains may have iron wires inside Iron wire is the wire used in armor One shirt is about 650 degrees plus 350 degrees, you get a hat The belt transmission brings a lot of plus points in our experience First, it is smoother and quieter than the chain Second, it requires less maintenance and less care Normally, the chain will have to be washed However, the Quora belt does not need that The belt is also more flexible than the chain If some good-quality belts according to advertising can run up to 10,000 km Of course, advertising is like that However, we all know that advertising will be exaggerated and we will run less And in the process of operation when there is a problem with the Quora belt it will be safer than the chain So why is it less popular than the chain? Because when we talk about its disadvantages Oh my God The belt cannot be popular with the chain because it is more expensive It is more expensive than the chain Second, it is more bulky than the chain To set up a Quora belt on a motorbike it will need more parts bigger than the chain First, it needs two rows or I call it the front and back of the belt It is much bigger The reason is because the Quora belt when we press it like this it can't press as much as the chain The chain can hold a rope like this But the Quora belt can't With a normal rope like this The reason is because the front and back of the belt is much bigger than the chain So it is only suitable for big motorbikes such as Harley Davidson cruisers Yamaha VMAX or Ducati X Diavolo Moreover, replacing and installing the Quora belt will be much more complicated than the chain And the last reason is that the Quora belt loses more power than the chain so it is not suitable for high-performance motorbikes We often see Quora belts on cruisers because it is suitable for that type of motorbike They need to go long distances They also need to be quiet to bring good experiences to the user Also, cruisers are usually very big so they can install the Quora belt and still look very reasonable And the second type of motorbike that I want to talk about in this video is the crankshaft What is a crankshaft? Basically, it is a metal shaft and when the engine is running, the shaft is also running and through a set of gears then it will be transferred to the rear wheel Normally, this type of motorbike And just by its structure we can know its disadvantages The first disadvantage is that it is very big and heavy However, it is the most flexible type and has the least maintenance work BMW has been using crankshafts since 1923 and its reason comes from the boxer engine As we know, the boxer engine block has two gears on both sides so it will rotate the shaft in the middle At this time, the shaft will be along the body of the motorbike So such a setup is completely reasonable However, it is not only the boxer engine that uses crankshafts There are some other motorbikes such as Triumph's Rocket 3 It is a straight 3-cylinder However, this 3-cylinder is a straight 3-cylinder so its shaft is also along the body of the motorbike And the Rocket 3 is a straight 3-cylinder so it is completely reasonable Because if the 2,500cc 3-cylinder engine is placed horizontally, I think it is more like an anti-collision than an engine This is a complex type of transmission so it will require very good mechanical skills and BMW is doing the best in this In terms of maintenance, it is very suitable for adventure bikes However, it is the most power-consuming transmission so it is not suitable for high-performance motorbikes And the last thing we have to talk about is the chain The chain is the most common because it is the cheapest and easiest to install And one more important thing It is the most effective transmission because it is the least powerful Its disadvantage is that it is easier to break than the other two In addition, it takes a lot of maintenance It takes a lot of maintenance However, the maintenance of the chain is not too complicated So even if you do a lot, no one will complain The easy-to-replace chain is also a condition for us to adjust the bike Now, many people have different types of chain Yellow chain, red chain for the Ironman And who knows about the performance There are also new technologies such as O-ring It keeps the tightness of the chain Then we have a lot of chain manufacturers They have different technologies different materials to serve different purposes For example, there is also racing If you go normally, you will definitely have it Then go off-road It all has different types of chain However, there is one thing we need to say The chain is the most dangerous transmission because when the problem occurs it is the easiest to lock the rear wheel When the chain is broken the rear wheel is free to rotate However, when the chain is broken it can cause serious consequences However, because it is the cheapest most effective and easy to install the chain is still an ordinary choice for everyone Those are the advantages and disadvantages I want to share with you about 3 types of transmission in today's video I hope it will help you in choosing a bike to buy Thank you very much for watching the video Don't forget to like, share and subscribe to support us I wish you all good health See you in the next video
