Front cabin frame assembly adopting forked front girder assembly

Abstract

The invention discloses a front cabin frame assembly adopting a forked front girder assembly, which comprises a front anti-collision beam, an auxiliary frame assembly and the forked front girder assembly fixed on the rear sides of the left end part and the right end part of the front anti-collision beam, and the forked front girder assembly comprises a front girder assembly, a front carriage outerside longitudinal beam angle plate and a front floor cross beam extension piece, a front carriage outer side longitudinal beam angle plate extends and is fixed from the outer side of the middle-frontportion of the front girder assembly to the inner side of the threshold, a front floor cross beam extending piece extends and is fixed from the inner side of the middle-rear portion of the front girder assembly to the middle channel longitudinal beam, and the end of the auxiliary frame assembly is detachably fixed to the upper side of the middle of the corresponding front girder assembly. The ends of the auxiliary frame assembly are located on the front sides of the corresponding front carriage outer side longitudinal beam angle plates and the corresponding front floor cross beam extending pieces respectively. According to the forecabin frame assembly adopting the forked type front girder assembly, the problem that the force transmission path of a front collision girder area of a vehicleis single is solved, stress concentration of an auxiliary frame assembly during front collision is avoided, and riding comfort is guaranteed.

Description

technical field [0001] The invention relates to a front cabin frame assembly, in particular to a front cabin frame assembly using a bifurcated front beam assembly. Background technique [0002] The front frame in the traditional front cabin frame assembly is the main path of frontal force transmission during the frontal collision of the vehicle, which has high requirements on the conductivity of force and the continuity of structural rigidity changes, such as figure 1 As shown, in the traditional frame assembly of the front cabin, the frame of the vehicle model runs through the front and rear, and the force of the frontal collision is mainly transmitted through the main body of the frame from the front frame 01 at the front end to the front frame 02 at the rear end and then to the rear frame. The end of the assembly is fixed to the rear front frame 02 through the sub-frame mounting bracket 03, and the outer front side beam gusset 04 is fixed on the outside of the front front...
