What Is the Definition of Chassis?

The dominant meaning of the word chassis is:

  • the supporting base frame of a structure (such as an automobile or television)
    • Leaf springs are attached to the car’s chassis.
  • also: the steel frame and working parts (as of a motor vehicle or electronic device) like circuit components, components of a radio, or landing gear of an aircraft, exclusive of the body or housing like a window frame

The essential thing to understand about a car’s chassis is that it is the frame or skeleton where the rest of the car will be mounted to in construction. It is where the engine, wheels, axle, transmission, steering, brakes, and suspension is mounted. For modern vehicles the frame or chassis and the body of the car are melded together to form a single structure as opposed to early automobile production. This type of frame is known as a unibody. The shell of the car is made up of steel which then gets reinforced with braces that allow the car to handle all the forces that will be applied to the car when it’s driven. 

Types of Chassis

  1. Ladder frame – symmetrical longitudinal rails connected by a series of lateral support members to resemble a ladder.
  2. Unibody –  the body, floorboards, and major chassis structural support and crash-protection elements are welded, bonded, molded, or somehow joined into a single structural element
  3. Backbone tube – featuring a rigid spine that connected the front and rear suspension frames, one of which supported the powertrain
  4. X-frame – wherein the structural rails converge in the middle of the car, but this design provides little or no structural side impact protection.
  5. Perimeter frame – in which the framerails curve outboard between the tires to encompass the seating positions. 
  6. Platform frame – concept that unitized structural floor panels with the framerails for added stiffness. 
  7. Space frame –  internal framework of metal tubes or composite stringers bears most of the load while the exterior bodywork bears very little—like a human skeleton/skin setup

The History and Origin of the Word

It can be traced back to the year 1864. This word comes from the French châssis from chasse and the Latin capsa. Chasse was defined as “a rectangular steel or iron frame in which letterpress matter is locked (as for printing)”
