Type of Chassis-Part 1

Now there are 7 known frame chassis out there and each one of them have their own advantages and disadvantages. And I will discussed it one by one.
Now the frame chassis are

1. -Ladder
2. -Monocoque 
3. -ULSAB monocoque
4. -Backbone Chassis
5. -Glass fiber body
6. Carbon Fiber monocoque
7. -Aluminum spaceframe

LADDER CHASSIS


This is the earliest kind of chassis that have been use since the 60's and have been use by the whole world back then as a standard chassis. However, most SUV today still uses this type of frame. The term ladder come from the construction of said chassis come form the two longitudinal rails that interconnected by several lateral and cross braces that look like a ladder.

The longitude members are the main stress member as they deal with the load and longitudinal forces that have been caused by acceleration and braking. The lateral and cross members provide resistance to lateral forces and further increase torsional rigidity.

Now the advantages of Ladder chassis are easy and cheap to build by hand but the durability and safeness of this chassis are outdated compare to the new generation frame chassis.
The advantages of it are due to its 2 dimensional structure, the torsional rigidity is very much lower than other chassis especially when dealing with vertical load or bumps
As I said it earlier most SUV still use it now including some of the classic cars and Ford Crown Vic.
