Abstract: An independent suspension comprises upper and lower fork arms, elastic elements, shock absorber and fork arm positioning pivots. The fork arms are A-shaped, front ends of the fork arms respectively connect to upper and lower suspension points of a wheel, and rear ends of the fork arms connect to a vehicle frame through the elastic elements. The shock absorber mounts on top of the front end of the upper fork arm. Vehicle frame bearing pivot points and transmission parts are constructed on peripheries of the upper and lower fork arms. The arrangement absorbs bearing elastic forces by changing directions of force and the arms of force, to form multiple points supporting multiple elastic elements, so force applied on the wheel is distributed by multiple points, increasing average running speed. Increasing the number and arrangement of the elastic elements reduces vehicle height, optimizes space utilization and improves stability and running smoothness.

Abstract: 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.
