How Car Gearboxes Work

Motorists are largely unconcerned with how their vehicles function. The intricacies of car gearboxes aren't usually regarded as important knowledge to anybody other than mechanics. Nevertheless, as with any piece of technology, there are advantages to understanding, at least at a basic level, how it functions and what it does. If a limited knowledge of car gearboxes and their workings saves a motorist from driving an unsafe car, or from paying over the odds for gearbox repairs, then certainly it is worth swatting up.

It's a nicely known fact that the very best way to comprehend the workings of a machine is to get to grips with it, but taking apart the gearbox of any car you're really planning on driving isn't at all advisable, unless you're a mechanic. Rather, motorists can easily discover information about the workings of their gearboxes in manuals available online, in book shops or in some hardware stores. For the truly ignorant, although, photos in a book can even prove too much, so here are the extremely fundamentals.

Car gearboxes are a fundamental part in the 'making the car go' procedure. The gearbox converts engine speed into torque which propels the car forward. In a manual car, when the clutch is depressed by the driver, the sliding gear is disengaged from its original position so that it can slide up and down the gearbox, allowing the driver to choose the appropriate gear.

Automatic gearboxes on the other hand, select the right gear so that the driver doesn't have to. The quantity of stress in the engine, detected by a hydraulic method measuring fluid in the engine, influences the choice of gear. Automatic car gearboxes don't need the use of a driver-operated clutch because a torque converter engages the sliding gear.

The job of the car gearbox therefore is to convert engine speed to torque, propelling the car forward. Without its gearbox, your car simply won't be going anywhere. Whilst the job of the gearbox may seem simple, the gearbox itself is far from it. Great care should be taken of car gearboxes; they cannot easily be fixed by a non-professional. Indeed, it is advisable to choose carefully amongst mechanics when your car gearbox requires a repair, since some mechanics may be gearbox experts.
