[0025] like Figure 1 to Figure 3As shown, an embodiment of the utility model proposes a steering knuckle fatigue resistance enhancement structure, including a steering knuckle body 1, characterized in that an axial hole 16 is opened inside the steering knuckle body 1, a steering damper arm 2 is installed on the outer side of the steering knuckle body 1, a damping reinforcement rib 3 is embedded in the steering damper arm 2, a buffer vibration damping part 17 is provided at the end of the steering damper arm 2, a brake connecting rod 4 is provided on one side of the steering knuckle body 1, a brake reinforcement rib 5 is embedded in the brake connecting rod 4, a steering connecting rod 10 is installed at one end of the steering knuckle body 1, and a steering reinforcement rib 9 is embedded in the steering connecting rod 10.
[0026] like Figure 1 and Figure 3 As shown, the outer ring of the steering knuckle body 1 is provided with an outer reinforcing rib 15, the inner side of the outer reinforcing rib 15 is provided with an inner reinforcing rib 14, and the inner side of the inner reinforcing rib 14 is provided with a graphite ring 13. The rotation of the outer component and the internal shaft hole 16 of the steering knuckle body 1 is strengthened, and since the graphite plate 15 has the physical property of high temperature resistance, the interference of high temperature on the steering knuckle 1 body is reduced, and the steering knuckle is prevented from being broken due to high temperature.
[0027] like Figure 1 As shown, the outer surface of the steering knuckle body 1 is provided with a brake assembly connecting rod 6, the interior of the brake assembly connecting rod 6 is embedded with an assembly reinforcing rib 7, and one side of the brake assembly connecting rod 6 is provided with an ABS controller 8 to increase the braking effect.
[0028] like Figure 1 and Figure 3 As shown, the buffer vibration reduction part 17 is fixedly connected to the outer side of the steering knuckle body 1 through the steering vibration reduction arm 2, so as to effectively reduce the influence of external shock on the steering knuckle body 1.

[0030] As shown in FIG1 , the ends of the brake connecting rod 4 and the brake assembly connecting rod 6 are both provided with connecting holes, which can be connected to the external structure.

At the same time, the buffering and damping part 4 provided on the steering damper arm 2 plays a buffering role when connected with the steering damper arm 2. At the same time, the steering graphite ring 12 on the steering connecting rod 10 and the steering damper arm 2 effectively reduces the increase in brittleness caused by heat during rotation. At the same time, the steering knuckle body 1 is provided with an inner reinforcing rib 14, an outer reinforcing rib 15 and a graphite ring 13, which further improves the heat dissipation effect in the steering knuckle body 1 while increasing the external connection and reducing metal intolerance.
