Being a dirt bike lover, you would also be interested in getting all kinds of information associated with a dirt bike.
What makes a unique dirt bike from regular bikes that is the most important thing to understand. So here in this post, we will be talking about how does a dirt bike gearbox work?

It can be annoying if, while riding, something broke inside the bike.

And in that condition, if you know the working process of all the tools, you can easily understand your problem with the bike.
In my perspective, don’t be a rider; you also need to be a good mechanic for your dirt bike.

It can make you feel happy when you can come out of a situation where no one can help you. Before understanding how a gearbox works, you need to understand what is inside a gearbox and its working principle.

If you don’t know how to whip a dirt bike, then it can be more fun for you if you know this.

What is a Gearbox in a dirt bike?

When we talk about the Gearbox, it cannot be evident for a beginner because engineers and designers use many synonyms.

The Gearbox is also named a gear reducer and gear head.

So now, here we will talk about the basic definition of a gearbox, and that is “Gearbox is a component that consists of a series of integrated gears. It is inside a housing.”

Mainly Gearbox works like a system of gears that functions to alter the torque between a driving component and a load. Here we suppose a motor as the driving component.

The gears used inside a gearbox can be of different types, such as Bevel gears, Spiral gears, Planetary gears, and worm gears.
The gear is mounted on a shaft.

A rotating bearing rotates this shaft.

It is a mechanical method used to transfer the energy from one component to another component, resulting in an increase in torque and a decrease in speed, and vice versa.

Types of gearbox:

  • Constant-mesh gearbox
  • Sliding mesh gearbox
  • Synchromesh gearbox

Structure of a Gearbox

A gearbox consists of a driving gear with a particular diameter connected to the driving mechanism linked to another gear of larger and smaller diameter coupled to a driven mechanical load.

If the driving gear is linked with the smaller gear of size, then the driving mechanism will have a higher speed than the driving one.

And if the diameter will be more significant of the gear, then the rate of the driving mechanism will be lower than the driven one.

The Gearbox system and mechanism are used for achieving speed and torque.

If the dirt bike is going to move on an upward path, it will require higher torque, which can be achieved by lowering the speed at the same power. When the bike requires less torque, then the rate can be increased with the same power.
