Chassis is main supporting part of any vehicle for components like wheels upper body engine transmission etc.frame does same things.frame was earlier name of chassis the lighter and rigid you make it your car will performe better.
This pic is example of body over chassis.
Morden cars are made on monocoque chassis which looks combination of body and frame which supports most of car parts in it.

In the case of vehicles, the term rolling chassis means the frame plus the "running gear" like engine, transmission, drive shaft, differential, and suspension.
An under body (sometimes referred to as "coachwork"), which is usually not necessary for integrity of the structure, is built on the chassis to complete the vehicle.
For commercial vehicles, a rolling chassisconsists of an assembly of all the essential parts of a truck (without the body) to be ready for operation on the road.[3] The design of a pleasure car chassis will be different than one for commercial vehicles because of the heavier loads and constant work use.[4]Commercial vehicle manufacturers sell "chassis only", "cowl and chassis", as well as "chassis cab" versions that can be outfitted with specialized bodies. These include motor homes, fire engines, ambulances, box trucks, etc.
In particular applications, such as school buses, a government agency like National Highway Traffic Safety Administration(NHTSA) in the U.S. defines the design standards of chassis and body conversions.[5]
An armoured fighting vehicle's hull[6] serves as the chassis and comprises the bottom part of the AFV that includes the tracks, engine, driver's seat, and crew compartment. This describes the lower hull, although common usage might include the upper hull to mean the AFV without the turret. The hull serves as a basis for platforms on tanks, armoured personnel carriers, combat engineering vehicles, etc.
More about chassis
Read below ...
Backbone tube chassis is a type of automobile construction chassis that is similar to the body-on-frame design. Instead of a two-dimensional ladder-type structure, it consists of a strong tubular backbone (usually rectangular in cross section) that connects the front and rear suspension attachment areas. A body is then placed on this structure.
Body on frame :-
Body-on-frame is an automobile construction method by which a separate body is mounted on a relatively rigid frame or chassis that carries the engine and drivetrain. It was the original method of building automobiles and continues to this day. In the late 19th century frames might be made of wood reinforced by steel flitch plates but in the early 20th century steel ladder frames or chassis rapidly became standard.
Mass production of all-metal bodies began with the Budd Company and the Dodge Brothers but prior to that bodies, like those of the carriages they replaced, were made of metal panels fastened to wooden (commonly ash) (body)-frames.
Mass production of all-metal bodies became general in the 1920s but Europe, with exceptions, followed almost a decade later. Europe's custom-made or "coachbuilt" cars usually contained some wood framing or used aluminium alloy castings.
