AI Technical Summary
In the prior art, the rear mounting bracket of the lower control arm of the front suspension has structural shortcomings due to its non-integrated design. The connection gaps and assembly tolerances result in uneven support, which cannot form a continuous force transmission path. It has weak resistance to deformation and is prone to loosening, displacement or breakage, affecting the stability and safety of the suspension system.
The trapezoidal connecting plate and the frame beam mounting bracket form a triangular structure, which is fixed by slots and limit bolts. The supporting stability is enhanced by reinforcing steel plates, and the weight is reduced by the design of the top plate and connecting groove, forming a double-layer triangular structure to enhance the supporting force, prevent loosening, and achieve a continuous force transmission path.
It improves the support stability and connection firmness of the bracket, enhances the overall load-bearing capacity, reduces weight, ensures the stable operation of the suspension system under bumps or impacts, and adapts to the dynamic load requirements of the vehicle during driving.
