The Definitive Guide to gearbox kereta auto

Apabila pembakaran berlaku dalam enjin anda, kuasa dipindahkan kepada crankshaft yang berputar ribuan kali seminit. Namun, ini terlalu cepat bagi roda, jadi kotak gear menukar kuasa kepada kelajuan putaran yang roda dapat kawal.

The valve system Within the transmission is chargeable for directing hydraulic strain to the appropriate bands and clutches. It gets pressurized fluid from the leading pump and includes several spring-loaded valves, Look at balls, and servo pistons. In older automatic transmissions, the valves utilize the pump stress as well as stress from the centrifugal governor around the output facet (in addition to other inputs, which include throttle place or the motive force locking out the higher gears) to regulate which ratio is chosen. Because the auto and engine adjust speed, the difference between the pressures variations, creating distinct sets of valves to open up and close.

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 General Motors Hydra-Matic grew to become the very first mass-generated automatic transmission following its introduction in 1939 (1940 design year). Offered as a possibility in vehicles including the Oldsmobile Series 60 and Cadillac Sixty Distinctive, the Hydra-Matic mixed a fluid coupling with 3 hydraulically managed planetary gearsets to supply 4 ahead speeds furthermore reverse. The transmission was delicate to motor throttle position and street velocity, manufacturing fully automatic up- and down-shifting that assorted according to working ailments. Features in the Hydra-Matic involved a large distribute of ratios (permitting equally teruskan fantastic acceleration in first gear and cruising at minimal engine pace in top rated equipment) and the fluid coupling handling merely a portion of the engine's torque in the highest two gears (raising gasoline economy in These gears, much like a lock-up torque converter).

An automobile may appear straightforward to function mainly because we rely on them daily, however They may be really intricate devices. The automatic transmission is One of the most intricate devices found in a conventional car.

On cars and trucks without the need of paddle shifters you can still change gears manually by tapping the equipment lever backwards and forwards, but If you prefer a chance to change gears through paddle shifters It really is well worth checking if they are included as conventional.

Minyak ATF yang telah lama digunakan mengandungi enapan-enapan minyak dan serpihan besi yang boleh menyebabkan keadaan minyak menjadi likat. Minyak yang semakin likat ini boleh merosakkan prestasi kotak equipment kereta anda dan menyebabakan suhu di dalamnya lebih tinggi daripada biasa.

Sentiasa periksa tahap dan keadaan minyak gearbox. Minyak yang kotor atau rendah boleh menyebabkan kerosakan pada gearbox.

The 1st automatic transmission to make use of a torque converter (in lieu of a fluid coupling) was the Buick Dynaflow, which was launched for the 1948 product yr. In ordinary driving, the Dynaflow utilised only the top rated gear, depending on the torque multiplication in the torque convertor at lessen speeds. The Dynaflow was followed by the Packard Ultramatic in mid-1949 and the Chevrolet Powerglide for the 1950 model calendar year. Each and every of these transmissions experienced only two ahead speeds, counting on the converter for additional torque multiplication.

CVT means Constantly Variable Transmission. It's a type of automatic gearbox, however it differs from typical components in a single key way. Instead of employing regular gears where drivers can come to feel the transitions, CVT gearboxes Have a very cone-formed structure and also a technique of pulleys to create a sleek transition up and down the car's electricity range, based on the International Journal of Scientific & Engineering Research. This is often an efficient process that's usually Utilized in hybrid autos.

Kotak gear jenis handbook dilengkapi dengan mekanisme mekatronik bagi mengambil alih tugas klac dan menukar gear. Ianya disambung dengan sistem klac yang akan menyambung kuasa dari enjin ke gearbox berdasarkan input daripada pemandu.
