Whether the Sutar is a dry dual clutch or a wet type

The Volkswagen Sutar and the engine are equipped with a dry gearbox and a wet gearbox.

Difference Between Wet and Dry Transmission:

1. Response speed.

The dry clutch is transmitted through the direct contact of the metal sheet, the power transmission is more direct, the metal plate is compressed, the transmission ratio is increased, and the effect is direct and significant; The wet type should use the oil as the "middleman", from the speed of the driving disc to the increase of the centrifugal force of the oil, and then to the speed of the driven disc, there is an additional set of procedures, so the response speed will be a little slower.

2. Transmission efficiency.

From the structure of the clutch, we can see that the structure of the wet clutch is more complex, and the complex structure means higher energy loss, so the transmission efficiency of the wet dual-clutch gearbox is lower, which takes up more engine power, and under the condition that other factors remain the same, it means that the fuel consumption will be higher.

3. Withstand torque.

The metal friction plate of the dry clutch can not withstand too much torque, if it receives too much stress impact, it is easy to cause damage to the friction plate, therefore, the dry clutch can only be used for small displacement and low torque output models, and even, in order to adapt to the dry clutch, some models deliberately put the torque output of the engine in low gear, in order to protect the transmission clutch.

The new 2015 model is equipped with a dry dual-clutch transmission. At present, among the domestic Volkswagen 7-speed dual-clutch transmission, only the Lingdu 330 is a wet dual-clutch.

Dry dual-clutch, I've been using the car for a year, there is no problem, if you still mind the dual-clutch, go buy that 6at.

Both the Sutar and the engine are equipped with a dry gearbox, equipped with a wet gearbox, whether dry or wet working principle is basically the same, there are two clutches working in turns. However, the connecting medium of the driving disc and the driven disc of the clutch is different, the dry dual clutch relies on air, and the wet dual clutch relies on oil.

The difference between a dry dual clutch and a wet dual clutch is that the two have different clutch plates working environment. Wet dual clutch plates are clutch plates that are immersed in transmission fluid, while dry dual clutch plates are in direct contact with the engine flywheel.

From the perspective of technical maturity and reliability, the wet dual clutch is more stable to use because the clutch plate works in the hydraulic oil, and the oil plays a certain role in heat dissipation.

Because of poor heat dissipation, dry dual clutch is prone to the risk of high temperature or even ablation of clutch plates in congested urban areas. At this level, the wet dual-clutch transmission technology is more mature. At the same time, the wet dual-clutch structure is complex, the manufacturing cost is high, and its power transmission efficiency is not as high as that of the dry type.

The Sutar uses a 7-speed dry dual-clutch gearbox; It is powered by a seven-speed wet dual-clutch transmission. At present, the Volkswagen dual-clutch transmission does the best and has stable performance.

Volkswagen must use a high-profit dry dual-clutch in the Chinese market, anyway, Chinese people like or are used to being pitted.

Sutar uses a dry dual-clutch gearbox. The dual-clutch transmission is a common automatic transmission with a very simple structure. The dual-clutch gearbox is a product developed on the basis of the manual transmission, and only has one more clutch and one set of shift control mechanism than the manual transmission.

The dual-clutch gearbox has one clutch to control odd-numbered gears and the other clutch to control even-numbered gears.

The dual-clutch gearbox has a fast shift speed and high transmission efficiency.

There are two types of dual-clutch transmissions, one is dry and the other is wet.

The clutch plates of a dry dual-clutch transmission are not soaked in transmission oil, and the clutch plates of a wet dual-clutch transmission are immersed in transmission oil.

The dry dual-clutch gearbox has fast shifting speed and high transmission efficiency.

The wet dual-clutch transmission can withstand higher torque, and the reliability and stability are also better.

Many sports cars use a dual-clutch gearbox, which gives the driver a feeling of neat shifting.

The use of a dual-clutch transmission can also improve the fuel economy of the car.

The common ones in the world are AT gearboxes and CVT gearboxes.

AT transmission is currently the most mature and widely used automatic transmission.

The dual-clutch transmission used in the new Sutar is dry. Sutar is Volkswagen's A-segment family car. The new Sutar has a height of 2,731 mm, a length, width of 4,753 mm, a width of 1,800 mm and a height of 1,462 mm.

**Sutar uses two engines, one is a turbocharged engine and the other is a turbocharged engine.

The dual-clutch transmission is a product developed on the basis of the manual transmission. The structure of this gearbox is similar to that of a manual gearbox.

The dual-clutch transmission has only one more clutch and a shift control mechanism than the manual transmission.

The dual-clutch gearbox has one clutch to control odd-numbered gears and the other to control even-numbered gears.

The dual-clutch variable closed gearbox has fast gear shift speed and high transmission efficiency.

There are two types of dual-clutch transmissions, one is dry and the other is wet.

The clutch plates of a dry dual-clutch transmission are not soaked in the transmission oil, whereas the clutch plates of a wet dual-clutch transmission are soaked in the transmission oil.

The dry dual-clutch transmission is more efficient and shifts faster.

The wet dual-clutch transmission is more reliable and stable, and this transmission can handle more torque.

Therefore, high-power cars will use wet dual-clutch transmissions, and ordinary family cars will use dry dual-clutch transmissions.

Millions of car purchase subsidies.

The Volkswagen Sutar and engine are equipped with a dry gearbox, and the engine is equipped with a wet gearbox. The wet dual-clutch variable box must have a hydraulic pump, lubricating fluid, cooling pipes and an external cooling system. By eliminating the associated wave force system, the advantages of dry clutches in terms of manufacturing cost, light weight, and structural optimization will be in vain.

In addition, since the dry dual-clutch has no hydraulic resistance, the transmission efficiency will be higher than that of the wet dual-clutch, and the fuel economy will be better.

The correct way to operate the transmission is:

1.Fill the valve slightly. Before shifting gears (upshifting), first adjust the throttle slightly higher and add a certain amount of oil to give the engine enough power to ensure that the speed of the vehicle does not decrease when upshifting.

3.Hold the clutch handle quickly. Almost at the same time as closing the throttle, close the clutch handle with the four fingers of your left hand (thumb is still on the steering handle), get rid of the clutch as soon as possible, and prepare to shift gears;

4.Press the shift pedal. Immediately after holding the clutch handle with your left hand, press the shift pedal and rear pedal with the sole of your left foot or heel and shift into high gear. The strength of the pedaling should be just right, the movement should be clean and neat, it is strictly forbidden to be slow and slow, and do not pedal continuously;

5.Release the clutch handle evenly. After the left heel presses the rear pedal lever of the shift, the left hand immediately releases the clutch handle, and engages the disengaged clutch in a timely and smooth manner, so that the engine power is quickly transmitted to the rear driver, and is ready to increase the speed;

6.Step on the gas. When the left hand releases the clutch handle, the right hand turns the throttle knob downward and backward in time, so that the closed throttle can be opened with a moderate opening, and the opening should not be too large or too violent.

The Volkswagen Sutar and the engine are equipped with a dry gearbox and a wet gearbox. The wet dual-clutch transmission must have a fluid pump, lubricating fluid, cooling pipe and external cooling system, and the dry dual-clutch will have more advantages in terms of manufacturing cost, lightweight, and space structure optimization due to the saving of the relevant wave force system.

In addition, since the dry dual clutch has no hydraulic resistance, the transmission efficiency will be relatively high, and the fuel economy will also be more advantageous than the wet type.

The correct way to operate the transmission is:

2. Quickly grip the clutch grip. Almost as soon as you close the throttle, hold the clutch grip with the 4 fingers of your left hand (your thumb is still on the steering handlebar) and disengage the clutch as quickly as possible to get ready for shifting.

3. Step on the shifter pedal. As soon as you hold the clutch grip with your left hand, step on the rear tread lever with the ball of your left foot or heel to shift into high gear. The power of the pedal should be just right, the action should be clean and neat, and the mud and water should not be dragged and the water should not be pedaled continuously.

4. Relax the clutch grip evenly. After stepping on the shifting rear pedal lever with the left heel, the left hand immediately releases the clutch grip and engages the disengaged clutch in time and smoothly, so that the engine power is quickly transmitted to the rear transmission, ready to increase the speed of the vehicle.

5. Increase the throttle. When the left hand releases the clutch grip, the right hand turns the throttle knob downward in time to the rear, so that the closed throttle opens, the opening should be moderate, not too large or too strong.
