Transmission CVT gearbox mountain running scrapped?

In fact, playing car friends we all like to find a place to zip your own car, a run came to experience the speed and passion, which is the most favorite friend of the mountain, the route complex twists and turns, exciting, is the most fun, of course, we do not encourage mountain racing, we must ensure security.

Having said that, in fact, I also ran across the mountain many times, what type of car which are opened, each driving experience not only because of the strength of the force varies, there is a reaction and gearbox logic, a good gearbox can bring you the most hearty of experience, of course, except manual transmission.

A few days ago and friends the opportunity to work in the mountain trot a bit, but can not open any performance car, but the sounds of nature known as a large sofa, models for the 2015 models 2.0L + CVT, ran nearly 60,000 km of old car, you might think I'm crazy, but in fact, there is indeed a problem.

In a brief mountain course, I only had the usual run mountain of half intensity, throttle give a little more, the entire acceleration process is not a lot, because, after all, is not a performance car, to measure the limit problem, it is more convergence, but about 5 minutes of a small hill a red light, the car suddenly appeared at the end of a small mountain road entering the main road under setback, and then the situation appeared not to throttle back the speed, nearly 4,000 had already stepped forward, but only to keep less than 30km/h speed.

It was only the feeling there are two situations, first, the transmission is broken, the second, transmission protection. Under tried several times stepped on the accelerator, for P file still did not improve the situation, decisive turn off the restart, then returned to normal, this is my first encounter this problem.

It was discovered that this is the so-called thermal protection CVT gearbox, this car owners have come across in many CVT transmission models, sometimes appear on the highway. The kicks me in the mountain of intense driving, so there has been transmission overload fever, so this issue has also cautioned that the CVT models take to run the mountain, is absolutely unwise.

CVT gearbox Why not suitable for mountain running?

First, it said works CVT transmission, CVT gearbox called the CVT continuously variable transmission, it is not by changing the gear ratio shift, but by cones and steel wheels, sliding on the bevel gear constantly through the strip the change in radius ratio change is completed, step staircase is equal to aT, the CVT slide to sit, constantly shifting.

Then it comes to this point, because just relying on friction strip to complete the ratio, so the slippage problem is certainly there, although there are programs designed anti-slip, but still inevitable, especially in mountain running I when Bigfoot throttle, it will obviously feel frustrated sudden acceleration, which is slipping performance.

Like AT and dual-clutch gearbox can be implemented quickly to ensure continuous downshift deceleration, while the CVT gearbox reason most are not suitable for mountain running is that it can not downshift fast, but a little bit of speed, so fast down the speed of gearbox are super-strength friction of steel wheels and cones are irreversible damage.

to sum up:

Like CVT gearbox is now basically being used in some models of the main economic comfort, as the ride is good, as long as there is no non-skid frustrated, located at the city everyday driving. So if you choose a CVT transmission models, do not choose intense driving, if you like to play car, do not select the CVT transmission models.
