What is the difference between the Cvt gearbox of Toyota Velanda and the traditional gearbox?

At present, the main type of automatic transmission is ATM. Continuously variable transmission. AT.DCM The new Toyota Highlander is equipped with an E-cvt, which is no longer a cvt in the traditional sense. S-cvt is an ordinary continuously variable transmission. There are complex mechanisms including clutch, torque converter or gear shaft group in traditional transmission, and e-CVT can be said to be a heterogeneous transmission. The official definition of e-CVT is power distributor, which is used to coordinate the relationship between motor and engine. It has no complicated mechanism such as clutch, torque converter or gear shaft set in the traditional gearbox system, but is a power distribution mechanism specially prepared for hybrid electric vehicles.

The traditional AT is followed by gears of different sizes, and AT uses computer to control different transmission ratios to realize speed change. AT present, most cars still use AT as automatic transmission, because the technology is mature and easy to maintain, while the traditional cvt transmits power through grinding between steel belt and cone disk, and obtains different transmission ratios through conveyor belts with different heights on the cone surface, which is excessively natural and smooth, with good comfort and no obvious shift impact feeling like AT.

But the transmission form of cvt limits the transmission of large torque. Excessive torque will cause the metal belt and cone disk to slip, which is not suitable for large displacement engines. Previously used for small displacement vehicles. However, the technology is better. At present, engines above 3.0 also use cvt.

The 2.0L power engine adopts high-speed combustion technology, the thermal efficiency reaches 40%, and the comprehensive fuel consumption is as low as 5.7L/ 100km. Matching the direct shift -CVT gearbox which can simulate 10 speed, the acceleration is smooth and the fuel efficiency is excellent.

Wilanda only uses the direct gear shift-CVT.

Use the starting gear to prevent excessive torque slip.
