Traditional split type knuckle need can be connected with braking system through the mounting panel, during the installation, need install four bolts and four nuts on the mounting panel, troublesome poeration and steadiness are poor, and mechanical strength is not enough. In order to solve the problem that the traditional split type knuckle assembly efficiency is low, the product total weight is big (a mounting panel is added), mechanical strength is not enough, the utility model discloses an integral structure has reduced the assembly of mounting panel and two bolts, two nuts, has improved production efficiency. Meanwhile, the weight of each steering knuckle is reduced by about 0.5kg, the front axle assembly can be reduced by 1kg, the purchasing cost is reduced, the labor intensity of workers is reduced by about 40-50%, and the efficiency is improved by 40-50%.
