How a Gearbox Works

If you are at all unsure about how a gearbox works, you certainly wouldn’t be alone. Many UK motorists know that this higher the gear number, the faster you go, and with a change of sound pitch, there’s definitely something going on, but some do not understand the principle of gears, and for those who wish to check their understanding, here is a brief description of the inner workings of a gearbox.

Gearing

If you have two cogs of different sizes that are intermeshed, one will turn the other. You might be thinking that the power from the crankshaft can simply be transmitted to the wheels, but the engine is running at very high RPM, this is too much power for the wheels, therefore a gearing system of varying cogs is used to transfer the power while reducing it to desired levels.

There are two main shafts in a constant mesh gearbox, each with interlocking cogs, and with several sizes, you have several power levels, which can either be manually or automatically shifted. Gearboxes can be either:

  • Manual – The gears are shifted by engaging a clutch that allows the change to take place. Many racing drivers prefer manual gears, as you have far more control of the power delivery, and by keeping the engine at prime rpm, you go faster.
  • Automatic– Once the engine reaches a certain level of power, the gear changer will make the shift, which is a very popular option, as you do not have to depress a clutch pedal every time you want to change gear.
