The Basic Principles Of gearbox kereta auto



DCTs, with their immediate gear shifts and efficiency, have become preferred in both equally substantial-functionality and each day autos. The rise of hybrid and electric automobiles within the 21st century introduced new types of gearboxes, including solitary-velocity and multi-velocity transmissions precisely made to manage the properties of electric motors. 

Jika anda meletakkan kereta di kawasan berbukit, pastikan kedudukan gear kereta berada di P. Jangan lupa pula tarik brek tangan.

Brake bands and clutches actuate the switching of gears within the planetary gearset. Brake bands tighten to carry a selected gear stationary or loosen to permit that equipment to spin. And it is actually the combination of stationary and spinning gears within the gearset that makes Every single personal gear ratio.

Even so, you’re almost never acting around the gearbox instantly; you’re just supplying it an Digital command. Some tend to be more promptly obedient than Many others, Nevertheless they generally do That which you inquire.

This ability lets you go away your automobile in Drive while you have your foot firmly to the brake when stopped at a stoplight. When you launch the brake, the torque converter enables the vehicle to creep forward.

Second speed gear: By working the gear shift lever, the more substantial equipment of the main shaft is disengaged from the primary equipment of the countershaft, after which the scaled-down equipment of the primary shaft meshes with the next equipment with the countershaft.

Meskipun begitu, dalam sesetengah keadaan, enjin kereta berbau hangit boleh berlaku disebabkan masalah-masalah lain seperti plastik atau teras pemanas yang mencair, bendalir antibeku yang menitik dalam ruang enjin.

Masalah begini hanya dapat dikawal dengan membuang semua minyak gear dan memasukan minyak gear semula dan dibuangkan.oil seal gearbox juga wajib ditukar dan speedometer harus diperiksa untuk memastikan air tidak berjaya menembusi speedometer ketika mencuci enjin atau melanggar becak yang besar.

Most vehicles utilize a "P–R–N–D–L" layout to the gear selector, which is made of the subsequent positions:[34]

Neutral (N): This placement disengages the transmission in the motor, letting the automobile to move whatever the engine's velocity. Prolonged motion on the vehicle in neutral Together with the motor off at considerable speeds ("coasting") can problems some automatic transmissions, Find Out More since the lubrication pump is frequently run from the enter facet of the transmission and is also as a result not functioning once the transmission is in neutral. The vehicle may very well be commenced in neutral in addition to park.

The clutches during the transmission have an analogous function, helping to determine the particular gear ratio the planetary gearset is making at that moment.

These manumatic transmissions present the driving force bigger Handle around the gear range that the standard modes to limit the transmission for the decreased gears.
