Haval h4' s gearbox model specification is 7DCT. This gearbox of Haval H4 generally emphasizes family use and attaches importance to the rationality of gasoline and diesel. The gearbox is unwilling to downshift from beginning to end during driving, and the situation of maintaining low speed ratio is also related to its market positioning. During cruising, when the average speed is 60 kilometers per hour, the gearbox will keep the sixth gear, and the speed ratio is about 65,438+0,300 rpm, which is very special.
Haval h4 gearbox, as the first batch of 7DCT gearboxes produced by domestic brands, has obvious practical significance. The greater feature of this gearbox is that the transmission system is extremely efficient, up to more than 95%. The gearbox has also won the title of the top ten gearboxes in the world with its powerful features and 85 patented technologies and independent patents. In order to ensure the reliability of such a good automobile engine, it is said that its test cycle has exceeded 14000 days, and at the same time, the whole vehicle experiments have been carried out in various extreme natural environments such as high temperature, severe cold, ultra-low temperature, new roads and deserts. In this case, the reliability of this gearbox equipped by Haval H4 is ok.
DCT is different from ordinary DualClutchTransmission)DCT system software. It is a manual gear instead of an automatic gear. In addition to the coordination ability of manual transmission and the comfort of automatic transmission, it can also ensure uninterrupted energy output. However, the traditional manual transmission uses a clutch. When shifting gears, the driver must step on the clutch pedal to engage the transmission gear of the differential gear. During shifting, the driving force is interrupted and the main performance is intermittent.
