Ikuti jadual penyelenggaraan yang disyorkan oleh pengeluar dan sentiasa periksa keadaan minyak gearbox untuk mengelakkan kerosakan yang lebih serius di masa hadapan.
Pemeriksaan berkala: Lakukan pemeriksaan berkala ke atas gearbox dan komponen lain kenderaan. Pastikan minyak dalam keadaan bersih dan mencukupi. Perhatikan bunyi yang tidak biasa atau tanda-tanda kebocoran minyak.
Automatic gearboxes aren’t precisely new. In reality, it may be argued which the pretty very first generation car or truck, the 1886 Benz Patent Motorwagen, experienced one particular; it undoubtedly didn’t Have got a clutch pedal. What’s specified, even though, is that they’re now available in virtually any vehicle you could possibly point out.
Minyak transmisi berfungsi sebagai pelincir untuk mengurangkan geseran dan juga sebagai media hidraulik yang membolehkan gear bergerak dalam gearbox. Kebocoran bendalir transmisi adalah masalah serius kerana ia mengurangkan jumlah pelincir yang diperlukan untuk melindungi gear dan komponen dalam gearbox.
As being the automobile slowed down and motor pace lessened, the gearbox would shift again to very low. However, the transmission was susceptible to unexpected failure, as a result of transmission remaining unable to withstand forces from the abrupt equipment adjustments.
The final Motors Hydra-Matic became the 1st mass-created automatic transmission adhering to its introduction in 1939 (1940 design 12 months). Out there as an option in vehicles like the Oldsmobile Sequence 60 and Cadillac Sixty Specific, the Hydra-Matic merged a fluid coupling with a few hydraulically managed planetary gearsets to create 4 forward speeds furthermore reverse. The transmission was sensitive to engine throttle posture and highway pace, manufacturing absolutely automatic up- and down-shifting that diversified Based on operating conditions. Features of the Hydra-Matic bundled a broad unfold of ratios (enabling each superior acceleration in 1st gear and cruising at very low engine velocity in best equipment) plus the fluid coupling managing only a percentage of the engine's torque in the top two gears (increasing gasoline financial system in These gears, similar to a lock-up torque converter).
Autos with automatic gearboxes are generally dearer to purchase new than manual models, and they tend to retain that excess benefit secondhand, particularly in lessons where by this sort of gearboxes are reasonably uncommon or where by an auto ’box is anticipated.
On automobiles without paddle shifters it is possible to still adjust gears manually by tapping the equipment lever backwards and forwards, but If you'd like the ability to change gears through paddle shifters It is truly worth examining if they are involved as normal.
Jika kereta belum berhenti sepenuhnya, gearbox boleh rosak. akibat pertukaran mengejut dari D terus ke R secara tidak sengaja akibat tertekan tombol equipment.
In more recent automatic transmissions, the valves are managed by solenoids.[fifteen] These solenoids are Laptop-controlled, Together with the gear variety determined by a focused transmission Regulate unit (TCU) or sometimes this functionality is built-in to the engine Regulate unit (ECU). Modern models have replaced the centrifugal governor having an Digital speed sensor that is definitely employed as an input to the TCU or ECU. Modern-day transmissions also factor in the level of load on an engine at any given time, which is set from either the throttle situation or the amount of consumption manifold vacuum.[15]
In truth, a developing number of new cars and trucks can be obtained only using a twin-clutch ’box, such as the mild hybrid variations in the Seat Leon and Volkswagen Golf relatives hatchbacks. Portion of the reason is they’re extremely effective. However, they’re also gearbox kereta auto incredibly complex.
Most techniques use solenoids which happen to be controlled by both the motor Command unit, or possibly a different transmission Manage device. This enables For additional precise control of change details, shift top quality, decreased shift instances and guide Command.
The pump transforms motor ability into transmission fluid, which powers the torque converter’s turbine. This raises the fluid’s electrical power, which makes it possible for the turbine to get supplemental power.
Pastikan anda mengekalkan jarak yang selamat antara kereta anda dengan kereta di hadapan. Ini memberi anda masa yang cukup untuk bertindak balas jika perlu berhenti atau memperlahankan kereta.
