[0002] The steering knuckle, also known as the "ram's horn", is one of the important parts in the automobile steering axle. It can make the car run stably and sensitively transmit the driving direction. The function of the steering knuckle is to transmit and bear the front load of the car, support and drive the front wheels to rotate around the kingpin to turn the car. When the car is driving, it is subjected to variable impact loads, therefore, it is required to have very high strength.

[0003] A Chinese patent discloses a vehicle and a steering knuckle thereof (publication number: CN111284559B). The steering knuckle of the vehicle comprises a steering knuckle body, on which a plurality of mounting holes and a bearing hole for mounting a wheel hub bearing are opened. The steering knuckle body can be fixedly connected to the wheel hub bearing through the plurality of mounting holes.

[0004] After the steering knuckle has been used for a long time, the friction between the steering knuckle and the wheel hub causes the lubrication effect inside to be poor, and it is cumbersome and inconvenient for the user to add lubricant. At the same time, the lubrication effect lasts for a short time, so when the steering knuckle is rubbed, abnormal noise is generated, which affects the user experience. Utility Model Content
