Live axle:
- Consists of a solid axle that is connected to the wheels on both sides.
- When one wheel moves, the other wheel also moves in the same direction, providing a solid and stable connection.
- Transfers power from the engine to both rear wheels simultaneously.
- Live axles are often preferred for go-karts used for racing or off-road activities because they provide better traction and handling.
- However, they can also make the ride less comfortable and can create more stress on the drivetrain components due to the rigid connection between the wheels.
Fixed axle:
- Consists of a stationary axle that is mounted to the frame of the go-kart.
- The wheels are independently attached to the axle and can rotate freely.
- This configuration allows each wheel to move independently of the other, which can provide a smoother ride and better shock absorption.
- However, fixed axles may be less efficient in transferring power from the engine to the wheels due to the increased number of moving parts and potential for power loss.
- Fixed axles are common on go-karts used for leisure purposes or for younger riders.
In summary, the main difference between a live axle and a fixed axle on a go-kart is the connection between the wheels. A live axle has a solid connection between the wheels, while a fixed axle allows the wheels to rotate independently. The choice between the two depends on the intended use and specific requirements of the go-kart, such as stability, traction, and ride comfort.
