Tahap minyak transmisi yang mencukupi bukan sahaja mencegah geseran berlebihan tetapi juga membantu mengekalkan keupayaan gearbox. Sekiranya anda mendapati kereta auto lambat masuk gear, ini mungkin tanda awal keperluan menukar minyak transmisi atau memeriksa kebocoran pada sistem tersebut.
Bagi memudahkan pemahaman, di bawah ini saya senaraikan lapan suggestions mudah memeriksa dan menjaga gearbox kereta anda.
Apabila equipment secara tiba-tiba bertukar tanpa kawalan atau kembali ke neutral, ini menunjukkan masalah serius pada gearbox yang memerlukan perhatian segera.
Kereta baru perlu ditukar minyak gearbox pada one thousand kilometer yang pertama kerana, bahagian enjin dan gearbox kereta baru pasti dipenuhi dengan habuk-habuk besi yang boleh merosakkan enjin dan gearbox. Sebab itulah kebanyakan kereta baru ( tidak semua kerana bergantung kepada pengeluar) digalakkan untuk menukar minyak enjin dan minyak gearbox pada pemeriksaan percuma a thousand km.
That, broadly Talking, is how an automatic transmission works. You will discover sensors and valves that regulate and modify points, but that’s the basic gist of it.
one. Pump (aka impeller). The pump looks like a fan. It's a lot of blades radiating from its Heart. The pump is mounted on to the torque converter housing which consequently is bolted on to the engine’s flywheel.
In more recent automatic transmissions, the valves are managed by solenoids.[fifteen] These solenoids are Laptop-controlled, Together with the gear variety decided by a focused transmission Handle device (TCU) or often this operate is integrated in to the motor Regulate unit (ECU). Present day layouts have replaced the centrifugal governor with an Digital speed sensor that is definitely utilized being an input for the TCU or ECU. Modern transmissions also Consider the amount of load on an engine at Click Here For Info any specified time, which is set from possibly the throttle place or the quantity of ingestion manifold vacuum.[15]

A vehicle like This may have on out very quickly and would be just about undriveable.
In this article, we will do the job our way by means of an automatic transmission. We will start with The true secret to The complete process: planetary gearsets. Then we'll see how the transmission is put jointly, learn the way the controls function and focus on a few of the intricacies linked to managing a transmission.
This is when the black magic of automatic transmissions starts (we haven’t even gotten to planetary gears yet).
But obtaining that to happen involves lots of parts that have to operate in harmony in a number of situations again and again and once again. Allow me to share The main element factors:
