What are the commonly used transmission models for each model?

There is a DSG dual-clutch transmission and a Tib-Tronic transmission. Volkswagen does not currently use DSG in SUV models, and luxury cars such as the Phaeton do not have a large displacement. DSG transmission with car model:

Pologti, Lavida, Touran, Passat, Octavia, Bora, Sutar, Magotan , CC, Golf GTI, Scirocco EOS Beetle.

Although there are many types of vehicles, the structure is similar. This should be said to be the credit of standardization, but also the need for large-scale production lines. With the development of society, the progress of science and technology and the change of demand, the shape of railway vehicles has begun to change, especially the passenger car is no longer the same old face.

However, their basic structure has not changed significantly, but the specific parts have a more scientific and advanced structural design.

Generally speaking, the basic structure of the vehicle is composed of five parts: the car body, the undercarriage, the running part, the coupler buffer device and the braking device.

The body is the part of the vehicle that is used to load goods or passengers, and is the basis for the installation and connection of other components of the vehicle. The body of the early vehicles was mainly made of wood, supplemented by steel plates, bow rods, etc. In modern times, the car body is mainly steel structure or light metal structure.

Type

Continuously variable transmission.

Continuously variable transmissions are one of the most widely used. It is geared and has several fixed-value ratios. According to the different types of gear trains, there are two types of shaft fixed transmissions (ordinary transmissions) and shaft rotary transmissions (planetary gear transmissions).

Transmissions for passenger cars and light and medium-duty vans typically have a ratio of 3-5 forward gears and one reverse gear, and in combination transmissions for heavy trucks, there are more gears. The number of transmissions refers to the number of forward gears.

Continuously variable transmission.

Continuously variable speed refers to a variable speed system that can continuously obtain any gear ratio in the variable speed range. The continuously variable speed can be used to obtain the best possible match between the drive train and the engine operating conditions. Common CVTs are hydromechanical CVTs and metal belt CVTs.

Integrated transmission.

Integrated transmission refers to the hydromechanical transmission composed of hydraulic torque converter and gear type continuously variable transmission, and its transmission ratio can be continuously changed in the range of several intermittent between the maximum value and the minimum value, and it is widely used at present.

The transmission is a mechanism used to change the speed and torque from the engine, which can change the output shaft and input shaft transmission ratio in fixed or divided gears, also known as the gearbox. The transmission is composed of a transmission mechanism and a control mechanism, and some cars also have a power take-off mechanism. Most of the transmission mechanisms are driven by ordinary gears, and some are driven by planetary gears.

Ordinary gear transmission and transmission mechanism generally use sliding gears and synchronizers.

Automotive transmissions are classified into hydraulic automatic transmissions (AT), mechanical continuously variable automatic transmissions (CVT), electromechanical automatic transmissions (AMT), and dual-clutch transmissions (DSG).

1. AT is composed of hydraulic torque converter, planetary gear and hydraulic control system, and realizes variable speed torque through hydraulic transmission and gear combination. Among them, the torque converter is the most important component, which is composed of a pump wheel, a turbine and a guide wheel, and has the function of transmitting torque and clutch.

2. Compared with AT, CVT eliminates the need for complex and cumbersome gear combination transmission transmission, but the transmission adopts two sets of pulleys. The speed change is achieved by changing the contact radius of the drive wheel with the driven wheel belt. Due to the elimination of the gear drive, the gear ratio can be changed at will, the speed is more stable, and there is no sudden gear jumping.

3. AMT is a step-dependent automatic transmission like a hydraulic automatic transmission (AT). On the basis of the ordinary manual transmission, a microcomputer-controlled electric device is added, which replaces the manual operation of clutch disengagement, engagement, transmission selection and shift action, and realizes automatic gear shifting.

4. There is a clear difference between the DSG gearbox and the traditional automatic gearbox, and the DSG does not use a hydraulic torque converter from the beginning. This transmission is not produced on the basis of a conventional automatic transmission concept. The engineers who designed the DSG embarked on an innovative new technology path that skillfully combined the flexibility of a manual transmission with the convenience of a traditional automatic transmission.

There are two ways to classify automobile transmissions: according to the way the transmission ratio changes and according to the different ways of handling. According to the number of stages of the transmission ratio, the transmission can be divided into three types: stepless, stepless and comprehensive.

According to the transmission operation mode, it can be divided into three types: manual transmission, automatic transmission and manual automatic integrated transmission.

Transmissions are classified as follows:

Manual transmission.

Ordinary automatic transmission Ordinary automatic transmission with automatic manual integration.

CVT CVT CVT gearbox with gear.

Dual-clutch transmission.

Hello, the classification of gearboxes is: manual transmission, ordinary automatic transmission, ordinary automatic transmission with manual automatic, CVT continuously variable transmission, CVT gearbox with gear, dual-clutch transmission.

There are currently several types of automotive transmissions: manual transmission (MT) and automatic transmission (AT), as well as mechanical transmission (DSG) with electronically controlled automatic transmission for dual clutches. Among them, manual transmission can also be divided into 2 axes, 3 axles, 4 axes, etc., and automatic transmission can also be divided into ordinary mechanical hydraulic, electro-hydraulic, continuously variable speed (CVT), etc., and DSG can also be divided into electro-hydraulic and electro-mechanical two.

Manual luminous speed changer, semi-automatic transmission, dual-clutch transmission, automatic transmission, continuously automatic transmission.

Today, with the continuous advancement of science and technology, the relevant forms are becoming more and more diverse. Basically, it can be divided into two categories: "automatic" and "manual" depending on the mode of operation.

Principle. Each gear has a different transmission ratio, which is equivalent to the meshing of the pinion and the large gear can produce different speeds, and the low transmission ratio (3 gears and below) is used when driving at low speeds, and the speed of the large shaft is lower than the engine speed, according to the formula P=FV, the early change can obtain greater driving force;

At high speed, use high transmission ratio (4 gears and above), the speed of the large shaft is higher than the engine speed, reduce the traction force to obtain higher speed, and select the gear of different sizes to meshed with the gear of the large shaft when cutting gears.

Common automotive transmissions are as follows:

Manual transmission.

Models equipped with manual transmissions require the driver to use their hands and feet to switch gears while driving, but manual transmissions are not a hallmark of lower-spec models, and some see this direct communication with machinery as a pleasure. Manual transmissions are divided into gears, and our common ones are 5-speed manual transmissions and 6-speed manual transmissions.

2.Mechanical Transmission (AMT):

From the point of view of operation, the models equipped with AMT transmission can be classified as automatic transmission models, but in terms of structure, the AMT transmission adopts more manual transmission structure, but it controls the clutch through a set of servo mechanism, thereby liberating the driver's left foot. Today, most AMT transmissions use electro-hydraulic actuators to control the clutch and shift forks.

3.Hydraulic Automatic Transmission (AT):

This type of gearbox is composed of a hydraulic torque converter, a planetary gear mechanism, a hydraulic control system, an electronic control system, etc. At present, the vast majority of automatic transmission models on the market are equipped with this type of automatic transmission, and the number of gears is still one of the standards to measure the technical content. The original 4-speed automatic transmission is no longer the mainstream, at present, the average family car is mostly 5 or 6 gears, luxury cars are favored by more gears of automatic transmission, Range Rover Evoque, Mercedes-Benz C-Class and other models are also equipped with 9-speed automatic transmission.

Continuously variable gearbox:

In terms of driving operation, cars equipped with CVT transmissions also use a gear lever to select parking, reversing, neutral, and forward or manual gears, as early as 1886, the CVT continuously variable transmission was installed on a Mercedes-Benz car. However, due to the immaturity of various technologies at that time, the gearbox of this structure was not taken seriously at that time. With the continuous advancement of technology, CVT technology has also matured, and its advantages in transmission smoothness and fuel economy have been highlighted.

5.Dual-clutch automatic transmission:

In terms of operation mode, the double-defeat Kaishihe automatic transmission still belongs to the category of automatic transmission, but it is different from the hydraulic automatic transmission and CVT continuously variable transmission introduced in the previous article in terms of internal structure and gear shifting mode. It is somewhat similar to the AMT automatic transmission, both rely on the gears with different gear ratios between the switching shafts to change the transmission ratio, and the device responsible for cutting off or engaging the power is also realized by the clutch located at the input end of the transmission, but in terms of shift speed and shift quality, the more logical dual-clutch automatic transmission is better than the AMT transmission.
