Ramai yang tahu bawa kereta tapi tak tahu gearbox tu apa dan bagaimana ia berfungsi. Fungsi utama kotak gear adalah untuk mendapatkan kelajuan yang berbeza dan sesuai mengikut keadaan dan beban pada kenderaan, memindahkan tenaga, menyesuaikan daya penukaran dan berada pada posisi neutral untuk menghidupkan enjin.

The shift valve will delay a shift if the vehicle is accelerating promptly. If the vehicle accelerates gently, the change will manifest in a reduced speed. Let us explore what takes place once the car accelerates Carefully.

­Automatic transmissions Use a neat pump, referred to as a gear pump. The pump is frequently located in the quilt on the transmission. It draws fluid from the sump in the bottom of the transmission and feeds it to your hydraulic technique. Additionally, it feeds the transmission cooler and the torque converter.

Minyak ATF yang telah lama digunakan kebiasaannya mengandungi enapan-enapan minyak dan serpihan besi yang boleh menyebabkan keadaan minyak menjadi likat. Keadaan minyak yang semakin likat ini boleh menjejaskan prestasi gearbox anda dan menyebabkan suhu di dalam gearbox lebih tinggi dari biasa.

Initial Gear In to start with gear, the more compact Solar equipment is driven clockwise through the turbine while in the torque converter. The World provider tries to spin counterclockwise, but is held nonetheless with the just one-way clutch (which only will allow rotation in the clockwise path) as well as the ring equipment turns the output. The smaller equipment has thirty enamel and the ring gear has 72, And so the equipment ratio is:

On this transmission There's two bands. The bands in a transmission are, virtually, steel bands that wrap all around sections with the equipment educate and hook up with the housing. These are actuated by hydraulic cylinders In the scenario with the transmission.

Just about every of those 3 elements may be the input, the output or is usually held stationary. Deciding upon which piece performs which function establishes the equipment ratio for your gearset. Let us Look into just one planetary gearset.

Therefore the transmission makes use of gears to create more effective use of your motor's torque, and to help keep the engine operating at an proper speed. When towing or hauling heavy objects, your auto's transmission could possibly get very hot adequate to burn up up the transmission fluid.

Hence the output nak baca tak? spins when for every two-thirds of the rotation in the engine. Should the engine is turning at 2000 rotations for every minute (RPM), the output velocity is 3000 RPM. This enables cars to travel at freeway pace while the motor speed stays awesome and sluggish.

A DCT transmission delivers a seamless and productive driving working experience and is often seen in luxury vehicles.

Untuk makluman anda, kos untuk membaiki gearbox auto boleh mencecah hingga ribuan ringgit. Jadi sebelum bertambah parah, anda perlu kenali tanda awal kerosakan gearbox kereta agar lebih mudah dan seterusnya mengelakkan anda daripada terbeban dengan masalah kewangan yang besar. 

Dengan melakukan persediaan awal yang betul, proses pengiraan nisbah gear akan menjadi lebih lancar dan tepat.

The 2nd is definitely an overdrive -- the output speed is faster compared to the input speed. The last is a discount all over again, though the output route is reversed. There are lots of other ratios that could be gotten out of the planetary gear set, but they are the ones which might be relevant to our automatic transmission. You'll be able to see them inside the animation under:

This amazing piece of gearing has appeared on HowStuffWorks in advance of. You might identify it from the electrical screwdriver posting. An automatic transmission consists of two comprehensive planetary gearsets folded alongside one another into one particular part. See How Equipment Ratios Operate for an introduction to planetary gearsets.
