The setting of the mounting boss surface not only makes the utility model have a smaller weight, but also effectively ensures the rigidity of its structure, and the simple flat plate The structure not only makes it very convenient to load and unload, but also makes it easy to process and manufacture, and has lower manufacturing costs;

2. The utility model has a flat plate structure as a whole, and the front and back sides are mirror-image symmetrical, which can be applied to the use of left-handed vehicles and right-handed vehicles, and has strong versatility;

3. In this utility model, the surface of the installation boss of the steering gear installation hole and the frame installation hole is designed to be ring-shaped, and a ring-shaped installation boss concentric with the installation hole is formed on the periphery of the installation hole, and the ring-shaped installation boss is connected by ribs. Together, the structure further reduces its weight while ensuring the structural strength of the utility model;

4. The utility model is integrally formed through a forging process. The use of the forging process not only makes it have a lower manufacturing cost, but also can further reduce its weight, increase its yield strength, and prolong its service life;

5. Since the whole of the utility model is a flat plate structure, the mounting holes of the steering gear and the vehicle frame are easier to adjust and have strong applicability.
