The quality of Toyota CVT gearbox is still leveraged, and the slogan of "unbreakable Toyota" has not been in vain. Toyota CVT gearbox has entered the market for so many years, and its response to the gearbox is still good, but in terms of life, it is a CVT continuously variable gearbox after all, and it is no problem to run 300,000 kilometers, but if it can run 500,000 kilometers like a double clutch, it still feels a bit tossed. After all, in the later period of use, problems such as steel belt wear will inevitably occur, and the gearbox needs to be overhauled.

Is the quality of CVT gearbox reliable?

After so many years of development, the reliability of CVT gearbox has been recognized by the industry.

Different from MT manual gearbox and AT automatic manual gearbox, CVT stepless gearbox does not use gear transmission, but connects input and output shafts through steel belts to realize the conversion between transmission ratios. Because of this, the smoothness of CVT gearbox can be said to be the best among all gearboxes, and it has simple structure and convenient maintenance. However, the disadvantage of CVT gearbox has always been a hot topic of discussion, that is, the transmission efficiency is not high, and there is no way to bear excessive load, otherwise it is easy to slip.

Because CVT CVT has been criticized for its low transmission efficiency, especially when starting, the torque should not be too high, otherwise the steel belt will easily slip. In response to this phenomenon, Toyota and Aisin jointly built the gearbox of Diretc-shift CVT. This problem is well solved by using virtual gear and starting gear for direct drive. The gear is directly used for starting, so that the large torque during starting will not be directly transferred to the steel belt, so the wear of the steel belt is also reduced.
