American cars with CVT transmission - CVT itself has actually been around for a long time. The CVT concept itself has also been around since the 1870s. Judging from the free encyclopedia Wikipedia, in 1879, Milton Reeves, a pioneer in the United States automotive industry, invented the CVT system which at that time was still referred to as variable speed transmission.
CVT is a type of automatic transmission that uses a steel belt and 2 pulleys to adjust the ratio. The diameter of each pulley can change to be larger or smaller. This concept will be very different when compared to conventional automatic transmission systems that use gears to adjust the ratio.
CVT actually used this transmission for wood saw engines but in the same year he used it in cars and some industrial machines. As is known, CVT can be found on motorcycles that already have an automatic transmission. The Zenith Gradua 6HP was one of the first two-wheeled motorized vehicles to use the CVT system in 1911.

First Car with CVT Transmission - Based on the same sources as before, the Dutch four-wheel DAF 600 was the first mass car to use a CVT transmission in 1958. This transmission was known as the Variomatic and was eventually used in Volvo cars until the 1980s.
After that, in 1987, the second generation Ford Fiesta and the first generation Fiat Uno were among the first cars to use a CVT transmission with steel belts. This material makes this transmission stronger than the CVT transmission found in DAF cars.
Since then, CVT transmissions have continued to be used by many manufacturers. Each manufacturer also uses this system under a different name such as IVT for Hyundai and Kia or Xtronic for Nissan.
How does it work? - CVT transmission uses a pair of pulleys connected by a belt or steel belt. Two pulleys connected by this steel belt can expand and contract and move left or right according to the command according to engine speed and car speed. The change of the two pulleys makes the belt diameter also change. This diameter is the ratio of the teeth on the CVT transmission.
The existence of this gear ratio works extensively on the CVT transmission to perform gear shifts continuously, so there is no pause and pounding in every gear shift.
How Car Hydraulic Brakes and Its Components Work - You can compare it when driving a conventional automatic transmission car when changing gears, your head will be slightly jerked forward.
Advantages of CVT Transmission - CVT transmissions are lighter and more compact than conventional automatic transmissions. Of course, this weight also affects the car's fuel consumption. Therefore CVT transmission is said to be more efficient.
Not only that, the automatic transmission can also adjust the gear ratio instantly with a certain range which also makes fuel efficient. Many hybrid cars also use CVT transmission so that the use of fuel can be more efficient.
CVT transmission cars have also been programmed to maintain engine speed. This plays a role in providing optimal power when the car is running. In some situations, such as overtaking another vehicle, this is very useful.
Disadvantages of CVT Transmission - This system certainly has its drawbacks and every car owner should know about it. The simplest drawback that this car has is the sensation it gives to be less sporty.
This transmission system does provide a smoother driving experience but not everyone likes this because everyone has different desires. Another drawback is the sound is quite annoying. This is because the CVT system forces the engine to spin higher when compared to machines that use conventional automatics.
The cost of repairing a car with this transmission system is also more expensive when compared to other transmission systems. This is because the repair or replacement of components in this system must be carried out thoroughly and not only on the damaged parts.
American car with CVT transmission - American inventor Milton Reeves then used this type of transmission for chainsaws in 1879. Daimer Benz then filed a patent for friction belt-based CVT in Europe in 1886 and in America in 1935.
But history records the first car to use a CVT transmission, namely the discovery of a product from the Netherlands, namely the DAF 600 which was made for the public in 1958. The same transmission was later adopted by the next model by the manufacturer and also Volvo.
