Abstract

The utility model provides a cross member for a frame of a heavy-duty vehicle. According to the technical scheme, the cross member for the frame of the heavy-duty vehicle comprises a cross member body which has an arch groove-shaped structure; the vertical face of the cross member body is provided with a plurality of brake components and/or installation holes of electric appliance parts; two ends of the vertical face of the cross member are provided with notches respectively; and the upper and lower surfaces of the two ends of the vertical face of the cross member body are provided with connection plates which are used for being connected with a longitudinal member of the frame. The cross member has the advantages that due to the adoption of the structure, the two ends of the vertical face of the cross member body are provided with the notches respectively, so that the structural intensity near a deformation area of the frame can be obviously improved, the stress concentration can be reduced, and the service life of the frame can be greatly prolonged; and the cross member body has the arch groove-shaped structure, so that the gap between the cross member and components such as a gear box or a transmission shaft can be increased, and the arrangement of a finished vehicle is facilitated.

Description

The heavy goods vehicles cross member of frame
Technical field
The utility model relates to a kind of heavy goods vehicles cross member of frame, belongs to the auto parts and components field.
Background technology
In recent years, the increasing employing structure of heavy goods vehicles vehicle frame was so that car load arranged that the heavy goods vehicles cross member of frame mainly was arranged in the flex area two ends, caused stress concentration easily in the flex area of front wide and rear narrow vehicle frame, caused the vehicle frame distortion.
The location of the power drive system of heavy goods vehicles so that increase the ground Clearance of each big assembly, is improved the crossing ability of car load all improving at present.The gap of locating parts such as causing change speed gear box or transmission shaft after improving and crossbeam dwindles, and is not easy to car load and arranges.
The utility model content
It is high that the purpose of the utility model provides a kind of reliability, the heavy goods vehicles cross member of frame that technology is simple, be convenient to make, cost is low, practical.
To achieve these goals, the utility model adopts following technical scheme:
A kind of heavy goods vehicles cross member of frame; Comprise cross-beam body; Cross-beam body is an arcuate recess shape structure; A plurality of brake components are arranged the cross-beam body facade or/and the mounting hole of electric component, and cross-beam body facade two ends are otch respectively, and cross-beam body facade two ends upper and lower surfaces is provided with and is used for the connecting panel that links to each other with chassis side rail.
In the above-mentioned heavy goods vehicles cross member of frame, a plurality of connecting bores that connecting panel side band connects to ground.
In the above-mentioned heavy goods vehicles cross member of frame; Connecting panel has four, and connecting panel comprises longeron connecting portion that links to each other with chassis side rail and the crossbeam connecting portion that links to each other with cross-beam body, the downward bending of longeron connecting portion facade; The bending angle is identical with chassis side rail bending angle, the bending that makes progress of crossbeam connecting portion.
The connecting panel upper surface is captiveed joint with cross-beam body in the above-mentioned heavy goods vehicles cross member of frame.
Above-mentioned heavy goods vehicles cross member of frame center member body is connected through rivet with connecting panel, and there are four rivets each junction.
The beneficial effect of the utility model is:
Adopt The above results, cross-beam body facade two ends are otch respectively, can significantly improve near the structural strength of vehicle frame deforming zone, reduces stress concentration, prolongs the service life of vehicle frame greatly; Cross-beam body is an arcuate recess shape structure, can increase the gap between the parts such as crossbeam and change speed gear box or transmission shaft, is convenient to car load and arranges.
Description of drawings
Fig. 1 is the structural representation of this utility model heavy goods vehicles cross member of frame embodiment;
Fig. 2 is the main TV structure scheme drawing of heavy vehicle carriage crossbeam.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details, following explanation only is exemplary, does not limit the protection domain of the utility model.
Embodiment 1
With reference to accompanying drawing 1,2, a kind of heavy goods vehicles cross member of frame comprises cross-beam body 1, and cross-beam body 1 is an arcuate recess shape structure, can enlarge markedly the gap of crossbeam and change speed gear box or transmission shaft; A plurality of brake components are arranged cross-beam body 1 facade or/and the mounting hole 4 of electric component is convenient and practical; Cross-beam body 1 facade two ends are otch 3 respectively, can reduce the stress concentration that chassis torsion formula cross-beam body produces, and also can be used as the cable-through hole of top tube line, and are convenient and practical; Cross-beam body 1 facade two ends upper and lower surfaces is provided with and is used for the connecting panel 2 that links to each other with chassis side rail.
Embodiment 1
On the basis of embodiment 1, the utility model preferred version is: a plurality of connecting bores 5 that connecting panel 2 side bands connect to ground.
Embodiment 3
On the basis of embodiment 1, the utility model preferred version is: connecting panel 2 has four; Connecting panel 2 comprises longeron connecting portion 21 that links to each other with chassis side rail and the crossbeam connecting portion 22 that links to each other with cross-beam body 1; The downward bending of longeron connecting portion 21 facades, the bending angle is identical with chassis side rail bending angle, can crossbeam be fixed on the vehicle frame flex area; Upwards bendings of crossbeam connecting portion 22 can improve the setting height(from bottom) of cross-beam body 1.
Embodiment 4
On the basis of embodiment 1 or 2 or 3, the utility model preferred version is: connecting panel 2 upper surfaces are captiveed joint with cross-beam body 1.
Embodiment 5
On the basis of embodiment 4, the utility model preferred version is: cross-beam body 1 and connecting panel 2 are connected through rivet, and there are four rivets 6 each junction, and rivet connects the Joint strenght that can increase crossbeam, improves efficiency of assembling.Certainly cross-beam body 1 also can pass through bolt and nut connection with connecting panel 2.
The above only is the preferred embodiment of the utility model; Be not that the utility model is done any type of restriction; Though the utility model has disclosed through the foregoing description; But can not be used to limit the utility model, the technology contents of those skilled in the art's above-mentioned announcement capable of using is made many variations or improved equivalent embodiment, and these equivalent embodiment should belong to the scope of the technical scheme of the utility model.
