What is the Difference Between a Dual-Clutch Transmission and an Automatic Transmission?
1 Answers
Dual-clutch transmissions belong to the category of automatic transmissions and are one type of automatic transmission. The main differences between the two are as follows: 1. Vehicles without a clutch pedal are all considered automatic transmission models. Currently, there are three mainstream types of automatic transmissions in the market: manual-automatic transmissions, continuously variable transmissions (CVT), and dual-clutch transmissions. 2. A dual-clutch transmission, also known as a direct-shift gearbox, consists of a dual-clutch assembly with two sets of clutch plates. It simultaneously controls the actions of both clutch sets and gear sets through electronic and hydraulic mechanisms. The clutch serves as the switch for power transmission between the engine and the transmission, capable of both transmitting and cutting off power. Essentially, it is a combination of two manual transmissions matched with two clutches, featuring a simple structure and low production and R&D costs, making it suitable for affordable family cars. Due to its transmission principle being similar to that of a manual transmission, it offers very high transmission efficiency, minimal power loss, and correspondingly lower fuel consumption. Additionally, the presence of two clutches enables faster gear-shifting processes.
