Abstract
The utility model provides a cast cross beam for a medium-duty or heavy-duty truck with a double-drive rear axle. The cast cross beam comprises a cross beam body. A reinforcing plate is arranged between an upper top face of the cross beam body and a lower bottom face of the cross beam body. The cross section of the cross beam body is of an X shape. V-shaped thrust rod mounting bases and straight-pushing type thrust rod mounting bases are respectively symmetrically arranged on the front side face and the rear side face of the reinforcing plate. Reinforcing ribs are respectively arranged on the V-shaped thrust rod mounting bases and the straight-pushing type thrust rod mounting bases. The cast cross beam is wide in application range, high in integration degree, safe and reliable, and effectively improves assembling efficiency.
Description
Technical field
The utility model relates to the medium and heavy automobile casting beam of a kind of pair of driving back axle, belongs to medium and heavy technical field of automobile parts.
Background technology
Development along with domestic arteries of communication, power-handling capability and load-carrying capacity for medium and heavy truck propose higher and more diversified requirement, a large amount of two driving back axle vehicles are approved by market, and the suspension form that two driving back axles mate also is diversified, when the different suspension of coupling, the double-rear driving axle center needs different crossbeams to adapt to suspension.When coupling breakaway-element balance shaft suspension and rubber suspension, the crossbeam that the double-rear driving axle center needs to mate the V-type propelling rod adapts to suspension, when coupling integral type balance shaft suspension, the crossbeam that the double-rear driving axle center needs to mate the direct drive type propelling rod adapts to suspension, its integrated degree of the crossbeam of this structure is low, commonality is not strong, assembles cumbersome.In addition, because currently used crossbeam is the punching press crossbeam, its intensity is low, ruptures easily under bad working environments, has potential safety hazard.Existing in prior technology weak point that Here it is.
Summary of the invention
The technical problems to be solved in the utility model is exactly at the existing in prior technology deficiency, and a kind of medium and heavy automobile casting beam of two driving back axles of highly versatile is provided.
This programme is realized by following technical measures: the medium and heavy automobile of this pair driving back axle comprises cross-beam body with casting beam, be provided with brace panel between the last end face of described cross-beam body and the bottom surface, and the transversal surface of cross-beam body is " X " type, be symmetrically arranged with V-type propelling rod mount pad and direct drive type propelling rod mount pad on the two sides, front and back of brace panel respectively, be respectively arranged with reinforced rib on V-type propelling rod mount pad and the direct drive type propelling rod mount pad.
Above-mentioned V-type propelling rod mount pad, direct drive type propelling rod mount pad and reinforced rib and brace panel are one-body molded, to improve the intensity of cross-beam body.
The last end face of above-mentioned cross-beam body is provided with the cross-beam connecting plate mounting hole.
The left and right sides face of above-mentioned cross-beam body is respectively arranged with the vehicle frame installation base.
The bottom surface of above-mentioned cross-beam body is provided with balance shaft suspension mounting hole.
The beneficial effects of the utility model: applied widely, integrated degree height effectively improves efficiency of assembling, and is safe and reliable.

Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is the block diagram of Fig. 1.
Fig. 4 is use view of the present utility model.
Among the figure, 1 is cross-beam body, and 2 is direct drive type propelling rod mount pad, 3 is reinforced rib, 4 is V-type propelling rod mount pad, and 5 is the cross-beam connecting plate mounting hole, and 6 is the vehicle frame installation base, 7 is balance shaft suspension mounting hole, 8 is the V-type propelling rod, and 9 is cross-beam connecting plate, and 10 is suspension, 11 is vehicle frame, and 12 is brace panel.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
The medium and heavy automobile casting beam of a kind of pair of driving back axle, as shown in the figure, it comprises cross-beam body 1, the last end face of cross-beam body 1 is provided with cross-beam connecting plate mounting hole 5, the left and right sides face of cross-beam body 1 is respectively arranged with vehicle frame installation base 6, and the bottom surface of cross-beam body 1 is provided with balance shaft suspension mounting hole 7.Be provided with brace panel 12 between the last end face of described cross-beam body 1 and the bottom surface, and the transversal surface of cross-beam body 1 is " X " type, be symmetrically arranged with V-type propelling rod mount pad 4 and direct drive type propelling rod mount pad 2 on the two sides, front and back of brace panel 12 respectively, be respectively arranged with reinforced rib 3 on V-type propelling rod mount pad 4 and the direct drive type propelling rod mount pad 2, V-type propelling rod mount pad 4, direct drive type propelling rod mount pad 2 and reinforced rib 3 are one-body molded with brace panel 12.
During use, can select V-type propelling rod 8 or direct drive type propelling rod according to the suspension 10 that will mate.V-type propelling rod 8 is corresponding with the direct drive type propelling rod to be installed in V-type propelling rod mount pad 4 and the direct drive type propelling rod mount pad 2.V-type propelling rod 8 can mate breakaway-element balance shaft suspension and rubber suspension, and the direct drive type propelling rod can mate integral type balance shaft suspension, and the Applicable scope of cross-beam body 1 is wider.Can propulsive effort and the braking force that drive axle provides be passed to car load by V-type propelling rod 8 or direct drive type propelling rod.
Adopt cross-beam connecting plate 9 transition to be connected between cross-beam body 1 and the vehicle frame 11 earlier, fitting by vehicle frame installation base 6 and cross-beam connecting plate 9 and vehicle frame 11 in the left and right sides of cross-beam body 1, and uses the bolt connection.Riveted joint is adopted in being connected of the last end face of cross-beam body 1 and cross-beam connecting plate 9, bottom surface same with cross-beam connecting plate 9 applyings, and link together by bolt with suspension 10.The transversal surface of cross-beam body 1 is " X " type, makes that stressed distribution is more even, and is fixing more firm.
This cross-beam body 1 adopts casting integrated shaped structures form, and it distributes more even than the chemical constitution of punching type cross-beam body, and intensity is higher, and each corner and bending part all adopt fillet to handle, and outside face does not have corner angle, has avoided concentrating of stress.Therefore, effectively raise vehicle frame 11 integral rigidities, strengthened the ability to bear of the twisting resistance that vehicle frame 11 pairs of vehicles produce under sharply turning and the road conditions of jolting.
Simultaneously, be respectively arranged with reinforced rib 3, reinforced rib 3 on V-type propelling rod mount pad 4 and the direct drive type propelling rod mount pad 2
The intensity of propelling rod mount pad can be actv. improved, the impulsive force and the twisting resistance that produce in the vehicle operating process can be resisted better.
Can pass through existing techniques in realizing without the technical characterictic of describing in the utility model, not repeat them here.
