What's the dry double release and transmission valve body?
The dual clutch gearbox DCT English, called DualClutchTransmission, Chinese translated as "direct shift gearbox", because it has two clutches, so there are a lot of people simply call it a dual clutch transmission. The clutch is located between the engine and the transmission, is the engine and the transmission power transmission "switch", it is one kind can transmit the power, but also can cut off the power transmission mechanism. Its function is mainly to ensure that the car can start smoothly and reduce the impact load of the gear change and prevent the transmission from being overloaded during the gear shift. In a general automobile, when the automobile is shifted, the clutch is separated and joined, and there is a temporary interruption of power transmission between the separation and the joint.
This kind of double clutch has been widely used in cars and cars. Audi's new Audi TT sports car and the new Audi A3 have already installed the DSG. Volkswagen all models are equipped with 6 speed or 7 speed dual clutch gearbox, and some domestic brands even double out of cooperation for the new models of selling points. The purpose of these car assembly DSG is to shift gears more smoothly than the automatic transmission without any hysteresis.
This has no effect on the average car, but in the race against time, if the clutch is not good, the power does not keep up, the speed will slow down, affecting the results.In order to solve this problem, in the early 80s, the automotive engineering will make a dual clutch transmission system, referred to as DSG (English Name: DirectShiftGearbox), the assembly on the car, can eliminate the power shift clutch transmission of stagnation. For example, the Bugatti EBl6. 4Veyron's new 7 speed transmission is equipped with dual clutches, shifting from one gear to the other, with no more than 0.2 seconds.
