Abstract
The utility model discloses a third cross beam for an automobile chassis, and relates to the field of automobile parts. The third cross beam comprises an upper cross beam piece and a lower cross beam piece, wherein the upper cross beam piece is stacked at the upper end of the lower cross beam piece and connected with the upper end of the lower cross beam piece through a rivet; and base plates are welded on assembly surfaces at two ends of each of the upper cross beam piece and the lower cross beam piece. The third cross beam has a rational structural design; gaskets are arranged on the two end faces of each of the upper cross beam piece and the lower cross beam piece respectively, so that the verticality and the planeness of the mounting surfaces are guaranteed; due to the base plates, gaps of assembly surface between the upper cross beam piece and a longitudinal beam as well as between the lower cross beam piece and the longitudinal beam are uniform; particularly, the planeness of the assembly surfaces of the upper cross beam piece and the lower cross beam piece is improved; and therefore, the strength of the cross beam and the longitudinal beam is guaranteed.
Description
Technical field:
The utility model relates to the automobile component field, relates in particular to a kind of the 3rd crossbeam of car chassis.
Background technology:
These parts are a kind of the 3rd crossbeam on the car chassis, and upper and lower pieces is that the crossbeam sheet metal forming with the thick 16MnL of 6mm forms, and upper and lower pieces connects through rivet.There is following problem in the prior art: the one, overside size (with the fitted position of Cong Liang) 850-851 is difficult to guarantee; The 2nd, because upper and lower pieces all is squareness and the planeness that profiled member is difficult to guarantee fitting surface.Owing to there are above 2 kinds of problems, make that the assembling of crossbeam and Cong Liang is difficult, and upper and lower pieces and fir beam fitting surface gap are inhomogeneous, particularly descend the planeness of part fitting surface poor; Because crossbeam upper and lower pieces and fir beam fitting surface gap are inhomogeneous, particularly descend the planeness of part fitting surface poor, these directly cause the intensity of fir crossbeam to fall the end.
The utility model content:
It is a kind of even with longeron fitting surface gap that the utility model technical matters to be solved is to provide, assembling easily, the 3rd crossbeam of the car chassis that intensity is high.
The utility model technical matters to be solved adopts following technical scheme to realize,
A kind of the 3rd crossbeam of car chassis comprises on the crossbeam part under the part and crossbeam, and part overlays part upper end under the crossbeam on the crossbeam, and connects through rivet, it is characterized in that: be welded with backing plate on the fitting surface of part two ends under part and the crossbeam on the said crossbeam.
Said backing plate is the thick steel plate of 2mm.
Compare with the 3rd crossbeam of existing car chassis, the size of part under part on the crossbeam and the crossbeam is short 4mm, the both ends of the surface of part are welded the thick pad of 2mm respectively under part on the crossbeam and crossbeam then, thereby guarantee the squareness and the planeness of attachment face.
The utility model reasonable in design; The both ends of the surface of part have increased pad respectively under part on the crossbeam and crossbeam; Thereby the squareness and the planeness of attachment face have been guaranteed; Backing plate makes on the crossbeam under the part and crossbeam part and fir beam fitting surface gap even, improved on the crossbeam planeness of part fitting surface under the part and crossbeam especially, so also guaranteed the intensity of fir crossbeam.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with specific embodiment and diagram, further set forth the utility model.
As shown in Figure 1, a kind of the 3rd crossbeam of car chassis comprises on the crossbeam part 2 under part 3 and the crossbeam, and part 3 overlays part 2 upper ends under the crossbeam on the crossbeam, and connects through rivet 4, is welded with backing plate 1 on the part 2 two ends fitting surfaces under part 3 and the crossbeam on the crossbeam.
Compare with the 3rd crossbeam of existing car chassis, the size of part 2 under part on the crossbeam 3 and the crossbeam is short 4mm, the both ends of the surface of part 2 are welded the thick pad of 2mm 1 respectively under part on the crossbeam 3 and crossbeam then, thereby guarantee the squareness and the planeness of attachment face.
More than show and described groundwork of the utility model and the advantage of principal character and the utility model.The technical personnel of the industry should be understood; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification sheets that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
