The Two Main Types Of Vehicle Chassis And Their Qualities Mobilityarena

This is the rigid metallic frame or skeleton of the vehicle to which all the mechanical parts are attached. The chassis is the backbone of the vehicle, thus it gives strength and stability to the vehicle.

TYPES OF VEHICLE CHASSIS

There are two main types of vehicle chassis, which are described below.

BODY-ON-FRAME CHASSIS

This is also known as the conventional chassis or the frame-full chassis. In this type of vehicle chassis, the body is made as a separate unit, then joined with a ladder frame. It is used in trucks, SUVs and bigger vehicles. This chassis is often built so solidly that it sustains little or no damage in an accident. ADVANTAGES

Higher load capacity and strengthEasier to repair after accidentsThe detachable bodywork allows for quicker, easier repairsEasier to design, build and modify

DISADVANTAGES

The body tends to vibrate easily, and the overall vehicle handling and refinement is lowerPerformance figures are low and fuel consumption is higher due to the weight.

UNIBODY CHASSIS

This is also known as integral chassis, frameless chassis, monocoque chassis, unit-body chassis and nonconventional chassis. In this type of vehicle chassis, the ladder frame is absent. Instead, the body itself acts as the frame for the vehicle. It supports all the vehicle systems. This type of chassis is mostly used in hatchbacks and sedan/saloon cars. ADVANTAGES

Less rattles and squeaksHandling is better due to the higher body rigidity and weightBetter fuel efficiency

DISADVANTAGES

The load-bearing capacity is much lowerIt suffers greatly in accidents

The unibody chassis is mostly used in modern vehicle types and is more suited for everyday, luxury and sort-oriented vehicles. On the other hand, the body-on-frame chassis is better suited for commercial and heavy-duty vehicles, pickup trucks, SUVs. The BMW i3 and i8 are rare examples of small cars with a separate body and frame.
