An integrated middle beam frame for new energy vehicles

Abstract

The invention provides an integrally-formed center-sill-type frame for a new energy vehicle. The integrally-formed center-sill-type frame comprises a center ridge, a front suspension support mountingarea, a rear suspension support mounting area and multiple rectangular frame beams. The enter ridge extends in the length direction of the vehicle; the front suspension support mounting area and the rear suspension support mounting area are arranged on the front and rear portions of the center ridge respectively; the rectangular frame beams are located between the front suspension support mountingarea and the rear suspension support mounting area, the rectangular frame beams and the center ridge are integrally formed, and the rectangular frame beams are used for providing attachment points ofsuspensions of the vehicle. The center-sill-type frame is manufactured through an integrally-formed method, the structure and technology feasibility is provided for adoption of high-strength steel, aluminium alloy, magnesium alloy and non-metal high-polymer materials for the frame, the cross section shape and size precision of all parts in the center-sill-type frame can be precisely controlled, by adopting integral formation, the mounting technology of multiple parts is avoided, and accordingly the material selection diversity, precision and assembly mounting efficiency of the center-sill-type frame are improved.

Description

technical field [0001] The invention relates to the technical field of frame structure of vehicles, especially commercial vehicles, and in particular to an integrally formed center beam frame for new energy vehicles. Background technique [0002] With the depletion of oil resources and the aggravation of environmental pollution, the emission requirements for automobiles are more stringent. The lightweight of the whole vehicle is one of the effective ways to save energy and reduce emissions. The application of the center beam frame can effectively reduce the weight of the whole vehicle. [0003] The center beam frame uses a central longitudinal beam that runs through the entire length of the car, also known as the spine frame. The middle beam frame has better anti-torsion rigidity and larger front wheel steering angle (large corner space), which allows the wheel to have a larger jumping space in structure, which is convenient for assembling independent suspension.
