The mounting bracket includes a bracket body 1, a plurality of mounting seats 2, and a reinforcing rib 3, wherein the bracket body 1 has a mounting cavity 11 and a notch portion 4, and the torsion beam is disposed in the mounting cavity 11, and the torsion beam is used to balance the wheels on both sides of the vehicle to reduce the shaking of the vehicle and ensure the smooth operation of the vehicle. The plurality of mounting seats 2 are respectively connected to the bracket body 1, and the plurality of mounting seats 2 are respectively used to connect the vehicle body to fix the torsion beam to the vehicle body. The reinforcing rib 3 is disposed on the bracket body 1 and extends to each mounting seat 2.
[0030] In this embodiment, the mounting bracket is made by casting and machining processes, which improves the dimensional accuracy and positional accuracy of the mounting bracket, thereby improving the assembly accuracy of the hard points of the entire vehicle, making it possible to match the hard points to a more suitable position according to performance requirements, reducing the impact and dependence on the position of the vehicle body frame.
[0031] The mounting bracket of the present embodiment includes a bracket body 1, a plurality of mounting seats 2 and a reinforcing rib 3. The bracket body 1 has a notch portion 4, which reduces the use of materials and reduces the weight of the mounting bracket.
