Onions, I found in the car when the gearbox is different, what is 5AT,6AT, how cars have 9AT, gear really matter?
Gearbox is one of the most important components of the car. And many friends in the car will struggle when the number of stalls, five-shift six-speed on which good, 789 tall? Onion today I shall tell you about stalls is necessary. First of all, for a car, and can’t be considered more stalls, the better, transmission gear, the more theoretically would bring better economic and ride, but more importantly and matching engine.
A lot of people think, small-displacement engine requires less gear, and large needs more stalls, this is actually incorrect, the small-displacement engines actually need more gears of the gearbox.
For example, let a friend ride a bike uphill, because power is relatively small, he definitely needs a multi gear bike to ride smoothly, and if there is an athlete, an ordinary car, can ride without having to speed up, but also faster. Power needed by weak car stalls, so that he could more easily pick up speed.
As for how much too much? Like we all know Golf 1.4T use 7-speed transmission, which is more, and the dual-clutch transmission loss of power is lower. Jeep Liberty 2.4L, used a 9AT gearbox, which was a bit too much, the end result is that 8,9 had little opportunity to hang up, onions is also thought for a moment, even hanging up 2.4 output torque powerful enough naturally aspirated engine is hard to push 8, 9. Constantly pursue more stalls, is wrong.
Various gear transmissions for large displacement engine is not perfect yet?
Now gearbox of document bit increasingly more, especially big displacement, but actually more is for fuel consumption and various emissions regulations of consider, and real movement type of car instead is not need too much of document bit, like had old paragraph of British Infiniti G35 3.5L of displacement, used has a Taiwan 5 speed automatically transmission, II document can will speed directly from 60km/h upgrade to 110km/h above, lower of for block frequency, and more wide of speed by brings of continued accelerated will to driving who brings very readily of driving feel. Of course making him relatively high fuel consumption. Later the G37 (3.7) large displacement, high power, Pack 7-speed gearbox, fuel directly down 2 liters per hundred kilometers, but too frequent shifting also made vehicles become too soft, accelerated achievement of the 0-100km/h there is no G35. For example, known as the Japanese God of GTR using a 6-speed gearbox, while the 8.0T Veyron only use 7-speed gearbox.
Usually stall number matches the engine power, manufacturers have for us to consider a, it is recommended that you select the transmission technology, such as the 1 series BMW from 1.6T to 6.0T of the 7-series 8-speed gearbox is used, that technically this transmission has more complete, you can fit a variety of dynamic matching.
Said so much, just wanted to tell everyone, don’t simply according to a car for more than a few stalls to determine vehicle ride quality. More important is the matching between engine and gearbox, this can only be to careful testing experience will be able to find better car. In the future, the onion will teach you how to feel, a car’s transmission and engine whether the match is excellent.
