Transition beam of truss type structure

Abstract

The invention discloses a transition beam with a truss structure. A power battery is arranged in the transition beam. The truss structure is set as a trapezoidal structure. The truss structure is divided into corresponding grids according to the shape, size and quantity of the batteries, and the batteries are placed in the grid horizontally. The truss structure The lap joint between the transition beam and the frame is connected, and a transverse reinforcement plate and a longitudinal reinforcement plate are respectively arranged at the transverse and longitudinal stress places for strengthening and fixing. The truss structure transition beam of the present invention is formed by cutting, drilling and welding rectangular steel, and the overall strength is relatively high; The stability of the car; the production process is completed by welding, the operation is simple, and there is no need to reopen the mold, and the cost is low; the truss-type structure transition beam also provides enough space for the arrangement of waterways, airways, and high and low voltage wiring harnesses.

Description

technical field [0001] The invention relates to a truss-type structural transition beam, which belongs to the technical field of automobiles. Background technique [0002] With the deepening of the global energy crisis, the depletion of oil resources and the increasing harm of air pollution and global temperature rise, governments and automobile companies generally recognize that energy saving and emission reduction are the main directions of future automobile development. As a new generation of transportation, electric vehicles have incomparable advantages over traditional vehicles in terms of energy saving, emission reduction, and reducing human dependence on traditional petroleum energy. The chassis is one of the four major systems of a car. Whether it is a traditional car or a new energy vehicle, the layout and adjustment of the chassis are very important. The quality of the chassis layout and adjustment directly affects the performance and stability of the vehicle. [...

AI Technical Summary

Problems solved by technology

[0004] At present, the power batteries of electric commercial vehicles of more than 5 tons generally use two batteries symmetrically arranged on both sides of the frame longitudinal beam. This method is prone to fanning, which will increase the amount of jitter of the vehicle and seriously affect the driving stability of the vehicle.
