Abstract
The utility model discloses the subframe assembly that a kind of structural strength is large, comprise Guan Liang after Guan Liang before the left Guan Liang of subframe, the right Guan Liang of subframe, subframe, subframe, install with the adapter plate pulsation-free of vehicle body junction, add reliability and safety for four of the subframe assembly that structural strength of the present utility model is large; Subframe central sill increases a reinforcing, swing arm is through on Guan Liang and welds, meet safety, reliability, rear-swing arm support welds with subframe left/right pipe beam and is being not a linear contact lay weld seam, change contact weld three peripheral welds extended with the arc surface of steel pipe into, strengthen fastness, safety and reliability.
Description
Technical field
The utility model belongs to automobile manufacturing field, the subframe assembly that specifically a kind of structural strength is large.
Background technology
With the develop rapidly of auto manufacturing, complicated suspension becomes assembly by loose mail.Same suspension assembly can be arranged on different vehicle bodies, briefly: subframe can regard the skeleton of tandem axle as, is the self-supporting body of the composition of tandem axle, traditional subframe, its hang be directly with vehicle body steel plate phase limit.Therefore the suspension rocker arm body of tandem axle is all loose mail, not assembly.After subframe is born, front and rear suspension is stupefied to be first assembled on subframe, forms a frame assembly, and then is together installed on vehicle body by this assembly.
Subframe assembly carrying electrical motor itself and retarder, oscillating arm bracket etc. before and after connecting, the subframe assembly upper steel plate that prior art uses and steel pipe are that strength and stiffness are inadequate, have cracking to occur soon and distortion after welding.Not, rear attachment point also only has a mounting nuts to have uneasy hidden danger for the subframe assembly in past and the weld strength of front side member four attachment points.
Utility model content
In order to solve the above-mentioned technical matters existed in prior art, the utility model provides the large subframe assembly of a kind of structural strength, comprise the left Guan Liang of subframe, the right Guan Liang of subframe, Guan Liang before subframe, Guan Liang after subframe, the left Guan Liang of described subframe, also central sill is welded with between the right Guan Liang of subframe, the left front welding support of swing arm, the right front welding support of swing arm is each passed through the left Guan Liang of subframe, the right Guan Liang of subframe is welded and fixed, before subframe, the two ends of Guan Liang are welded with front pipe beam mounting bracket, the left Guan Liang of subframe, the right Guan Liang of subframe is welded with respectively left pipe beam adapter plate and right pipe beam adapter plate, the left back mounting bracket of swing arm, the right back mounting bracket of swing arm is welded on the left Guan Liang of subframe respectively, on the right Guan Liang of subframe, the left suspension mounting bracket of motor, the right suspension mounting bracket of motor to be welded on before subframe on Guan Liang, motor rear-suspending mounting bracket is welded and fixed through Guan Liang after subframe.
Further, before the left Guan Liang of described subframe, the right Guan Liang of subframe, subframe, after Guan Liang, subframe, pipe beam material thickness is 2.5mm.
Further, the material thickness of the left front welding support of described swing arm, the right front welding support of swing arm, the left back mounting bracket of swing arm, the right back mounting bracket of swing arm is also 2.5mm.
Further, all welds are the full weld welding of contact both sides, shape face.
Install with the adapter plate pulsation-free of vehicle body junction, add reliability and safety for four of the subframe assembly that structural strength of the present utility model is large; Subframe central sill increases a reinforcing, and swing arm is through on Guan Liang and welds, and meets safety, reliability, rear-swing arm support welds with subframe left/right pipe beam and is being not a linear contact lay weld seam, change contact weld three peripheral welds extended with the arc surface of steel pipe into, strengthen fastness, safety.
Accompanying drawing explanation
Fig. 1 is the subframe assembly structure schematic diagram that structural strength of the present utility model is large.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the subframe assembly that structural strength of the present utility model is large, comprise the left pipe beam 1 of subframe, the right pipe beam 2 of subframe, pipe beam 3 before subframe, pipe beam 4 after subframe, the left pipe beam 1 of subframe, central sill 5 is also welded with between the right pipe beam 2 of subframe, the left front welding support 6 of swing arm, the right front welding support of swing arm 7 is each passed through the left pipe beam 1 of subframe, the right pipe beam 2 of subframe is welded and fixed, before subframe, the two ends of pipe beam 3 are welded with front pipe beam mounting bracket 8, the left pipe beam 1 of subframe, subframe right pipe beam 2 is welded with respectively left pipe beam adapter plate 9 and right pipe beam adapter plate 10, the left back mounting bracket 11 of swing arm, the right back mounting bracket of swing arm 12 is welded on the left pipe beam 1 of subframe respectively, on the right pipe beam 2 of subframe, the left front suspension mounting bracket 13 of motor, the right suspension mounting bracket 14 of motor to be welded on before subframe on pipe beam 3, motor rear-suspending mounting bracket 15 is welded and fixed through pipe beam 4 after subframe.
Before subframe left pipe beam 1, the right pipe beam 2 of subframe, subframe, after pipe beam 3, subframe, the material thickness of pipe beam 4 is 2.5mm, and the material thickness of the left front welding support of swing arm 6, the right front welding support of swing arm 7, the left back mounting bracket of swing arm 11, the right back mounting bracket 12 of swing arm is also 2.5mm.All welds also weld problem easy to crack by a linear contact lay, widen as welding by contact both sides, shape face full weld.Four attachment point flange installed with vehicle body serve, and controlling party is to the effect preventing subframe movement.
