What is a Dog-Ring Transmission?

 Transmission is one of the most important parts when transferring the power produced by the engine to the wheels. Today, there are a wide variety of transmission types, and there are systems that provide completely different types of transmission in racing vehicles. One of them is a sequential gearbox, and a completely different transmission is provided by the Dog-Ring system. So what is the Dog-Ring? The answer is in the rest of the article…

Dog-Ring is actually the name of a gear and is used in sequential transmissions. Therefore, first of all, it is necessary to inform about sequential gearboxes. What is a Sequential Transmission? We have explained the subject in detail in our article. Sequential Transmissions are configured to work faster than conventional manual transmissions by nature, and downshifts and upshifts are done manually with a kind of automated system. Therefore, it provides a very serious time advantage compared to conventional transmissions. Sequential transmission is used in motorcycles, rally cars, special sports cars and optionally modified cars. What is a Dog-Ring? The use of this term, which comes together from the words dog and ring in terms of its meaning, in the automotive industry is identified with the structure of the part. The Dog-Ring, which is used in the Dog-Box type transmissions, which is the other name of the sequential gearbox we have just mentioned, is to connect the two gears in a way to each other and hold them tightly. Due to its structure, Sequential Transmissions usually have a fixed transition structure in the form of 1N23456 and intermediate transitions are not made. So you can't go directly from second gear to fourth gear. First you shift into third gear and then the next. During this process, the clutch is not used and the command you give with your hand is sufficient to increase the gear. Considering you are in a race, this type of transmission saves tremendous time for sudden gear changes. While providing this, the gear gears need to be changed as soon as possible, and this is ensured by a piece called Dog-Ring, which keeps the next gear gear tightly. Until recently, the Abarth 695 Biposto was able to offer its Dog-Ring type transmission as an option to its customers as a series production car. Of course, it is necessary to pay a considerable amount of money for this. In addition, using sequential gearboxes in daily life can be tiring, while its life is shorter than ordinary manual gearboxes. Because the wear of the parts in fast gear changes is much higher than any manual geared vehicles, Dog-Ring transmissions are generally preferred in special cars.
