Types of Chassis and their advantages – disadvantages

 In Uncategorized

You have heard the word “Chassis” many times in automobile but till now you have confusion about it. But Today I am going to tell you about it. Chassis is the base of a vehicle. It consist engine,
transmission system, brake system, suspension system, steering system, cooling system, wheels etc.

There are two types of chassis:

  1. Conventional chassis or frame-full chassis

In this type of chassis the body is made as a separate unit and then joined with ladder frame. It
supports all the systems in a vehicle such as the Engine, Transmission system,
Steering system, Suspension system.

Advantage

  1. Higher load capacity and strength

Disadvantage

  1. The body tends to vibrate easily and the
    overall vehicle handling and refinement is lower.

It is used in truck, bus and in SUV cars and bigger vehicles.

  1. Non conventional or frameless chassis

In this type of chassis the ladder frame is absent and the body itself acts as the frame. It supports all the
systems in a vehicle such as the Engine, Transmission system, Steering system,
Suspension system.

Advantage

  1. Less rattles and squeaks are developed.
  2. Handling is better due to the higher body rigidity and weight.

Disadvantage

  1. The load carrying capacity is lower.
  2. It is not safe in accidental condition.

Such types of chassis are mostly in hatchback and sedan cars.
