Types of Axles

Axles are as diverse as the vehicles and machinery they support. They come in various types, each designed to meet specific needs and conditions. Understanding these types helps in selecting the right axle for optimal performance.

Live Axles

Live axles are among the most common types, known for their ability to transmit power from the engine to the wheels. They are typically found in rear-wheel and four-wheel drive vehicles.

Dead Axles

Unlike live axles, dead axles do not transmit power. Instead, they support the weight of the vehicle. They are often used in multi-axle trailers and trucks.

Tandem Axles

Tandem axles are a combination of two axles positioned close together, sharing the load. They are ideal for heavy-duty vehicles that require stability and weight distribution.

Stub Axles

Stub axles are short axles used in the front wheels of vehicles. They allow the wheels to pivot, facilitating steering.

How Does an Axle Work?

The functionality of an axle depends on its type and application. However, the fundamental principle remains the same: to support the weight and facilitate rotation.
