Unibody VS Body on Frame

承载式: Monocoque or Unibody are the terms used to indicate when the body of the vehicle is designed and built to support the weight of the vehicle and perform any other function of a chassis. This is achieved by strengthening the floor of the vehicle, the pillars and using bracing along various parts of the body.

非承载式: Ladder Chassis or Body on Frame are the terms used when the body of a vehicle is mounted to a separate frame or chassis. This frame is similar to a ladder in design as two long pieces of steel (approximately the length of the vehicle) are held parallel to each other by shorter pieces running across.
