Abstract
The invention discloses an automobile frame cross beam structure. The automobile frame cross beam structure comprises longitudinal beams and a cross beam of a frame, wherein the cross section of each longitudinal beam is in the shape of I, a hole is arranged on a web plate of each longitudinal beam, the two ends of the cross beam penetrate through the holes on the longitudinal beams and then fixedly connected with the holes, two gaps which are depressed downwards are arranged at the upper part of the cross beam, and the positions at the bottom, corresponding to the gaps which are depressed downwards, protrude downwards. As the two gaps which are depressed downwards are arranged at the upper part of the cross beam and the positions at the bottom, corresponding to the gaps which are depressed downwards, protrude downwards, and the depth of the depressed gaps is not less than the thickness of I-shaped upper end plates of the longitudinal beams, when the two ends of the cross beam penetrate through the longitudinal beams, the depressed gaps of the cross beam can enable the I-shaped upper end plates of the longitudinal beams to penetrate through, and the other parts are flush with the upper surfaces of the upper end plates of the longitudinal beams; and furthermore, if a bottom plate is arranged on the frame, or a box body is placed, flat steel does not need to be arranged on the cross beam for leveling, and the next process step can be directly implemented for operation.
Description
Technical field
The present invention relates to the automobile preparation field, be specifically related to the vehicle frame of lorry, superimposed trailer.
Background technology
The vehicle frame of lorry, superimposed trailer generally all is to be made up of longeron, crossbeam and frame, and then on vehicle frame, welds base plate, gets final product shipment.Wherein before longeron and crossbeam are welded to connect, need be in the set hole of longeron with the two ends of crossbeam.At present, longeron generally adopts channel-section steel, and the notch of the chassis side rail after the moulding is relative; And the shape master of crossbeam looks and is projected as rectangle, and after the set hole of longeron was passed at the crossbeam two ends, beam surface upper was lower than longeron upper surface (height that differs is the channel-section steel side plate thickness); Therefore; The band steel of same thickness need be set on crossbeam, can base plate be positioned on the vehicle frame, and then row is welded to connect.Know from above-mentioned, not only wasted metallic material, and the welding sequence of many one crossbeams and band steel, productive costs increased.
Summary of the invention
The technical matters that the present invention will solve provides a kind of automobile chassis frame beam structure, after the set hole of longeron is passed at the crossbeam two ends, can base plate be positioned on the vehicle frame, is welded to connect, and the productive costs of vehicle frame is low.
The present invention realizes through following technical scheme:
A kind of automobile chassis frame beam structure; The longeron, the crossbeam that comprise vehicle frame; The transversal surface of said longeron is I shape, and the former of longeron is provided with the hole, and the two ends of crossbeam are through set its captive joint of Kong Houyu of longeron; Said crossbeam top is provided with two breach to lower recess, protrudes downwards in the bottom to the breach correspondence position of lower recess.
The further improvement project of the present invention is that two interior angles of said depression breach are greater than 90 degree (being convenient to pass the hole of longeron).
The present invention further improvement project is, the degree of depth of said depression breach is more than or equal to the thickness of said longeron I shape upper head plate, and after crossbeam was fixedly connected on longeron, beam surface upper was concordant with longeron upper head plate upper surface.
The present invention compared with prior art has following obvious advantage:
The present invention is owing to be provided with two breach to lower recess with crossbeam top, protrudes downwards in the bottom to the breach correspondence position of lower recess, and simultaneously, the degree of depth of depression breach is more than or equal to the thickness of said longeron I shape upper head plate.Therefore, after longeron was run through at the crossbeam two ends, the breach of crossbeam depression let longeron I shape upper head plate, and remainder is concordant with longeron upper head plate upper surface.Therefore,, or place casing on vehicle frame, then need not on crossbeam, to be provided with the band steel levelling, can directly implement the subsequent processing operation if base plate is set.
Description of drawings
Fig. 1 is a crossbeam schematic side view of the present invention.
Fig. 2 is the vehicle frame schematic cross-sectional view.
The specific embodiment
Like Fig. 1, shown in 2, the present invention includes longeron 1, the crossbeam 2 of vehicle frame.The transversal surface of said longeron 1 is I shape, and the web 3 of longeron 1 is provided with the hole, and the two ends of crossbeam 2 are through set its captive joint of Kong Houyu of longeron 1.
As shown in Figure 1, said crossbeam 2 tops are provided with two breach 4 to lower recess, protrude downwards in the bottom to breach 4 correspondence positions of lower recess.Two interior angles of said depression breach 4 are 120 degree.Still as shown in Figure 1, the degree of depth of said depression breach 4 is slightly larger than the thickness of said longeron I shape upper head plate 5, and after crossbeam 2 was fixedly connected on longeron 1, crossbeam 2 upper surfaces were concordant with upper head plate 5 upper surfaces of longeron 1.
Claims (3)
1. automobile chassis frame beam structure; The longeron, the crossbeam that comprise vehicle frame; The transversal surface of said longeron is I shape, and the web of longeron is provided with the hole, and the two ends of crossbeam are through set its captive joint of Kong Houyu of longeron; It is characterized in that: said crossbeam top is provided with two breach to lower recess, protrudes downwards in the bottom to the breach correspondence position of lower recess.
2. a kind of automobile chassis frame beam structure as claimed in claim 1 is characterized in that: two interior angles of said depression breach are greater than 90 degree.
3. according to claim 1 or claim 2 a kind of automobile chassis frame beam structure; It is characterized in that: the degree of depth of said depression breach is more than or equal to the thickness of said longeron I shape upper head plate; After crossbeam was fixedly connected on longeron, beam surface upper was concordant with longeron upper head plate upper surface.
