Many small partners will tangled up some problems with dual-clutch gearboxes when they buy a car. Some people think that it is technically tall and others feel that it is failing. Let's talk about double-clutch matters today.
Double clutch gearboxes are divided into dry and wet ones. What are the differences between them?
When Volkswagen came out with a double-clutch fault door, the "wet" and "dry" twin clutches became a hot topic.
Dry clutch plates are characterized by direct friction and lighter weight. However, when starting and stopping frequently, the clutch will be in a semi-linkage state for a long time, and it is prone to overheating.
The characteristic of the wet dual clutch transmission is that the clutch system is soaked in the oil, which solves the problem of clutch overheating, and the wet dual clutch transmission can also withstand greater torque.
Is that dry dual clutch very easy to break?
This is not necessarily true. The reason for the dry-type dual-clutch “hanging†is multiple factors. One of the most fatal reasons is that the gearbox itself is overheated.
The most common cause of overheating is the frequent shifting of gears , such as severe congestion on the way to and from work every day. This is the dry dual clutch nemesis. The gearbox will switch back and forth between 1 and 2 stops.
If it is in a relatively smooth car environment, the possibility of failure is relatively small.
Like the sixth-generation golf of Xiao Zhang in the later period, it used the seven-speed dry-type double clutch . When it opened to 30,000 kilometers, it finally lost to the big traffic jam of the “Empire Cityâ€. Since his car was still under warranty at the time, he could go to the 4S shop for free repair. 4S shop to his car first upgrade the transmission program, after maintaining about 10,000 km, and later because of the gearbox shaking too badly, eventually replace the clutch disc. It is still normal after two years.
My car is the previous generation of imported Audi A3. It also uses a dry double clutch. It has now opened more than 90,000 kilometers, and nothing has happened.
In the event of a traffic jam , I usually cut the gearbox into manual mode. This can, on the one hand, reduce the transmission's jitter at low speeds, and on the other hand, it can relieve the wear caused by the clutch's frequent shifts to a certain extent .
Can double-clutch cars be bought?
In fact, I think the specific or to look at everyone's car environment , if you rarely drive traffic jams, are relatively unimpeded road environment, you can choose to double clutch. Double clutch shifting efficiency is high, high gear shifting is really smooth, and fuel consumption performance has certain advantages.
Nowadays, some car companies with a mass-based approach have improved their dual-clutch technology, and they have achieved a lot of improvement in smoothness and reliability. In particular, wet dual-clutch models will have better reliability.
However, if you are still worried that the gearbox is prone to problems, simply select an ordinary automatic transmission or CVT gearbox is better, after all, everyone's daily driving map is still worry.
All cylinders with a threaded necking are required to have cylinder caps in place when being stored full or empty. Compatible With Select cylinders, Product Type Cylinder cap. These caps have the durability to withstand cylinder falls and keep the valve protected Cylinder valve protection is paramount when moving or storing a cylinder.
