What makes the Bogie broken?

The advantage of the Bogie is light-weight, reduce the body of truck ‘s impact, improve the wheel ground adhesion, and truck’s center of the gravity can be down.

Here are the reasons below.

Tough Fracture.

When the parts bear applied load, the bogie can Elastic deformation. when the load over the limit of elasticity, the Bogie can plastic deformation. When the stress over the limit of strength,

bogie can fracture. This fracture called tough fracture.

Fatigue Fracture

According to the parts bear nature of load, repeated load fracture is also called fatigue fracture.

After repeatedly stress or load effect that make the semi-trailer axle fracture.
