Have you ever felt lost seeking to seem sensible of all Individuals gears in the guide transmission? Or wondered what in the world an automatic is carrying out when it modifications gears by alone? Shifting gears can sense puzzling, but it does not have to be.
An auto engine spins at significant rotation speeds calculated in revolutions per minute (RPM), generally as much as six,500rpm or even more at greatest output. Unfortunately, an engine's organic RPM selection is frequently unsuitable for simple driving. This is when the gearbox saves the working day.
Handbook gearboxes lose fewer electrical power throughout much less mechanical connections and want considerably less maintenance if operated correctly.
In 1923, a patent was accepted in The usa describing the operation of a transmission in which the guide shifting of gears and manual operation of the clutch was removed. This patent was submitted by Henry R. Hoffman from Chicago and was titled: Automatic Equipment Shift and Speed Command. The patent explained the workings of such a transmission as "...aquiring a series of clutches disposed intermediate the motor shaft as well as the differential shaft and during which the clutches are organized to selectively engage and push the differential shaft dependent on the speed at which the differential shaft rotates".
Pastikan kenderaan dalam keadaan berhenti sepenuhnya sebelum mengubah gear untuk memanjangkan jangka hayat gearbox anda.
Sebuah gearbox secara umumnya boleh bertahan lebih daripada a hundred and fifty,000 kilometer atau sepanjang hayat kereta dengan penyelenggaraan yang betul. Walau bagaimanapun, ada kalanya gearbox anda boleh mengalami kegagalan, seperti dengan tabiat memandu dan penyelenggaraan yang buruk.
An unsynchronized guide transmission, usually known as a "crash box," is among the earliest styles. It lacks synchronizers, which means gears don't automatically match velocity through shifts.
Some early passenger automobile automatics, such as the pre-1960 Chrysler autos along with the Corvair Powerglide, didn't have the park aspect in the slightest degree. These automobiles had been begun in neutral and essential the driver to use a parking brake when parked. The original Hydra-Matic from GM alternatively engaged a parking pawl when put in reverse Together with the motor off, Therefore dispensing with a park place until the adoption on the Managed Coupling Hydra-Matic in 1956.
Bunyi seperti dentingan, berdengung, atau hentakan semasa pemanduan menandakan ada komponen dalam gearbox yang teruskan tidak berfungsi dengan baik. Bunyi ini mungkin lebih ketara semasa menukar gear.
It truly is genuine that Components one drivers brake with their remaining ft. They are also remarkably expert drivers functioning automobiles which might be especially designed for this technique. Just brake and speed up together with your appropriate foot and go away your left foot off into the aspect.[seven] X Research supply

Jika anda mengesyaki terdapat masalah pada gearbox, segera bawa kenderaan ke bengkel bertauliah untuk pemeriksaan lanjut. Mekanik yang berpengalaman dapat mendiagnosis masalah dengan tepat dan mencadangkan penyelesaian yang sesuai.
Pada gearbox guide, kejadian equipment tergelincir biasanya disebabkan oleh clutch yang sudah haus, manakala pada gearbox automatik, ia boleh disebabkan oleh keausan pelbagai komponen seperti pelat clutch dan tali transmisi. Banyak kotak gear moden dilengkapi dengan ciri keselamatan seperti “manner limp” atau “mode selamat”, yang menghalang tergelincir lebih lanjut dengan mengunci pada satu gear tertentu apabila komputer keselamatan mengesan masalah dengan gearbox.
Overdrive is particularly helpful for long-length highway driving, in which sustaining a high speed with minimal motor hard work is beneficial.
