Sekiranya anda mengamalkan tabiat-tabiat seperti dibawah, anda boleh merosakkan equipment kereta anda terutamanya bagi yang mempunyai kereta dengan gear automatik. Menurut Engineering Discussed, ini adalah five tabiat buruk yang mampu membuatkan gearbox kereta rosak:
Utilizing this data and a complicated Regulate method based upon fuzzy logic -- a technique of programming Command units applying human-sort reasoning -- electronically controlled transmissions can perform such things as:
Some automatic transmissions feature a handbook method, letting drivers to control gear improvements if they wish. This can offer far more driver engagement with no have to have to get a clutch pedal.
Menunda penukaran minyak gearbox boleh menyebabkan minyak tersebut menjadi kotor dan kelikatan meningkat.
A effectively-executed manual change accelerates efficiently because of unbroken torque shipping. Though the manual gearbox relies exclusively on the driver's calibration of clutch, throttle and adhere shift timing.
A torque converter works by using fluid coupling in place of mechanical clutch plates to transmit rotation from motor to transmission.
The 2nd is an overdrive -- the output speed is faster compared to the input velocity. The last is a discount again, however the output direction is reversed. There are numerous other ratios which might be gotten out of this planetary equipment set, but they're those which can be pertinent to our automatic transmission. You may see them in the animation down below:
BMW uses an eight-pace automatic transmission in many of its products. This transmission is praised for its speedy, easy shifts and its contribution to the general driving dynamics and gas efficiency of BMW cars.

The gearbox houses a number of gears linked to the motor's crankshaft on 1 facet as well as auto's driveshaft on the opposite. Gears of varying sizes intermesh to control motor rotation to wheel rotation ratio. Greater gears slow down the RPMs, even though smaller sized gears increase RPMs.
Hence the output spins after for every two-thirds of a rotation of the motor. If the engine is popping at 2000 rotations for each moment (RPM), the output pace is 3000 RPM. This allows cars to push at freeway velocity when the motor pace stays nice and gradual.

These challenges pushed Koenigsegg to produce a proprietary transmission program called the “Mild Pace Transmission”. When its previously technology hypercar built usage of DCT transmission, the latest 2019 Jesko pushed so much electrical power that it essential some thing more long lasting for 1600 Nm of torque.
This adaptability allows the gearbox auto motor to perform properly in all ailments, which could save fuel and lower dress in and tear on the engine.
