The left and right sides be provided with adjustment hole, the inner chamber of the adjustment hole is provided with regulating bolt, and the left and right sides of the after-frame is opened
There is suspension mounting groove, the inner chamber of the suspension mounting groove is provided with suspension installation base, and the inner chamber of the suspension installation base is horizontal
To suspension mounting hole is provided with, the preceding face center position of the side arm is provided with hanged hook.
Preferably, the side arm use draws high the higher steel plate of intensity and is welded, and the after-frame is welded using aluminium alloy plate
Connect and form.
Preferably, suspension mounting groove is process using machine-shaping described in two groups.
Preferably, the suspension installation base is four groups of structure identical, and suspension installation base described in four groups is respectively symmetrically
It is arranged on the inner chamber of two groups of suspension mounting grooves.
Preferably, the surface of the after-frame and side arm is provided with corrosion-resistant coating, and corrosion-resistant coating is epoxy resin layer.
Compared with prior art, the beneficial effects of the invention are as follows：A kind of light-duty vehicle subframe that the invention proposes, after
Frame is welded using aluminium alloy plate, and side arm use draws high the higher steel plate of intensity and is welded, so that the subframe phase
Compare in light weight 25 the percent of traditional subframe, so as to reduce the weight of body of a motor car, reduce automobile
Energy consumption, be connected with vehicle body by side arm made of steel plate, be connected by after-frame made of aluminium alloy plate with automobile suspension rack,
Suspension mounting groove is provided with after-frame, then is connected by suspension mounting hole with automobile suspension rack, improves the stability of structure,
So as to bring suspension coupling stiffness well, the invention is easy to use, reduces the weight of body of a motor car, has saved the energy.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
In figure：1 after-frame, 2 side arms, 3 vehicle body mounting holes, 4 sleeves, 5 card columns, 6 regulating bolts, 7 adjustment holes, the installation of 8 suspensions
