A fixing hole 101 is provided at the top of the steering knuckle body 1. A first steering knuckle arm 2 is provided on the outer wall of the steering knuckle body 1. Reinforcing members 210 are fixed on both sides of the first steering knuckle arm 2. A second steering knuckle arm 3 is connected to one side of the steering knuckle body 1. A first fixing block 331 is fixed to the outer wall of the steering knuckle body 1. A reinforcing rod 330 is connected to the end of the first fixing block 331. A second fixing block 332 is fixed to the bottom of the second steering knuckle arm 3, and a reinforcing rod 330 is connected to one side of the second fixing block 332. During the process of the first steering knuckle arm 2 driving the vehicle steering device to rotate, the vehicle steering device will give the second steering knuckle arm 3 a certain force. The first steering knuckle arm 2 experiences a large reaction force. The I-shaped reinforcing members 210 on both sides of the first steering knuckle arm 2 share the force, thereby reducing the deformation of the first steering knuckle arm 2. During vehicle operation, the vehicle suspension system will experience bumps due to road terrain, causing misalignment between the steering knuckle body 1 and the vehicle suspension system. The reinforcing rod 330 fixed at the bottom of the second steering knuckle arm 3 provides a certain degree of support for the second steering knuckle arm 3, sharing the force in the vertical direction and reducing the compression deformation of the second steering knuckle arm 3 by the vehicle suspension system, thereby extending the service life of the steering knuckle body 1.
[0037] Please see Figure 2 and Figure 3The reinforcing member 210 is arranged in an I shape, and the end of the reinforcing member 210 is connected to the knuckle body 1.
