The present application discloses a wheel beam type axleless vehicle frame that comprises five sections in sequence from front to back, including a front hanging rack, a front wheel carrier, an intermediate coupling rack, a rear wheel carrier, and a rear hanging rack. Every two adjacent sections amongst the five sections are manufactured and connected in a unified and standardized integrated mode; a modular combination structure is used; and the five sections, which are independent respectively, may be assembled and adjusted according to requirements, and have sufficient strength and stiffness as well as completely independent interchangeability. The vehicle frame has the advantages that match with the needs of an electric vehicle, and thus may be used as the optimum configuration frame for the electric vehicle; and the vehicle frame may be improved according to requirements to be applicable to various fuel and hybrid electric passenger vehicles and commercial vehicles.
