What are the different types of automatic car transmissions, and what are their differences?
Car transmissions are mainly divided into: manual transmission and automatic transmission. Among them, automatic transmissions are further divided into ordinary automatic transmissions AT, AMT transmissions, CVT stepless transmissions / CVT transmissions with simulated gears, DSG dual-clutch transmissions, electronic stepless transmissions (E-CVT), and Honda's 8-speed DCT: Manual transmissions, also known as manual gears, require the use of a gear shift lever to change the meshing position of the gears inside the transmission, changing the gear ratio to achieve the purpose of changing speeds. The gear shift lever can only be moved when the clutch is fully depressed. Manual transmissions are the most traditional and oldest type of transmission. If driving

What are the advantages and disadvantages of automatic transmissions?
Automatic transmission cars are now commonplace, but there are many types of automatic transmissions, such as: continuously variable transmissions (CVT), automatic manual transmissions (AMT), dual-clutch transmissions (DCT), etc. So, do you know the advantages and disadvantages of these transmissions? Perhaps you really don't, so let's listen to my answer! First, let's talk about continuously variable transmissions (CVT): CVT transmissions are also known as CVT. Vehicles equipped with CVT transmissions mainly include Audi, Nissan, Subaru, Honda, Toyota, etc. It does not have multiple planetary gears, so it has no gears. It only relies on steel belts to transmit power. Since there is no engagement and separation of gear sets, there will be no interruption of power.

Future trends in automotive gears
First, the continuous entry of new car manufacturers is irreversible. In the past two years, traditional automakers have slowed their previous rapid development, even leading to concerns that some companies may gradually withdraw from the historical stage. However, at the same time, we have also seen many powerful companies flocking to the auto industry and quickly demonstrating their competitiveness in this trillion-dollar market. China's three internet giants BAT, as well as Apple and Google from overseas, and the aggressive new car manufacturers, are all strong contenders. Not long ago, Xu Jiayin, chairman of the board of directors of Evergrande Group, a real estate giant, held talks with automotive industry leaders such as Bosch and Magna in Germany, demonstrating a strong posture of "overtaking on a curve".

Why is the number of gear teeth so important?
As a power transmission component, gears are now increasingly related to life. For example, cars need to use gears, and electric vehicles and bicycles also need gears. In addition, gears mainly refer to the continuous meshing of gears on the rim to transmit power. They first appeared at the end of the 19th century. At that time, Switzerland invented the variable pull method and also processed gears, and then Britain, the United States, and Germany also successively developed gears. With the development of technology, the materials and processing methods of gears have also been upgraded and improved, and finally established as arc-shaped gears. It is understood that China, through decades of efforts and development, once in 2005

Why are the teeth on car transmission gears slanted?
The forward gear is the most frequently used gear in a car. Using helical gears ensures sufficient strength while also being quieter and more comfortable, so car transmissions basically all use helical gears. These gears are known as helical gears, and they have a relatively larger load-bearing capacity and less noise and vibration compared to straight gears. In addition, the number of teeth and the contact area engaged at the same time during the transmission process are limited for straight gears, unlike helical gears. Moreover, to transmit a larger torque, larger teeth are needed, and when the teeth are made larger, the size of the gear increases. However, the advantage of straight gears is that they can freely engage and disengage horizontally, and many automobile...

Common malfunctions and solutions for snail gear reducers
I. Common Problems and Their Causes Keywords: Speed reducer, Gearbox, Transmission 1. Speed reducer overheating and oil leakage. In order to improve efficiency, worm gear reducers generally use non-ferrous metals for worm gears, and harder steel for worm shafts. Due to sliding friction transmission, a lot of heat will be generated during operation, causing thermal expansion differences between the various parts and seals of the reducer, resulting in gaps in the various mating surfaces. Due to the increase in temperature, the lubricating oil becomes thinner and is prone to leakage. There are four main reasons for this situation: first, unreasonable material matching; second, poor quality of the meshing friction surface; third, insufficient lubrication oil addition
