Description

Technical Field

[0001] The utility model relates to the technical field of automotive parts, and particularly relates to a knuckle with a drainage groove. Background Art

[0002] In the design of existing automotive knuckles, as a key component connecting the wheels and the steering system, the performance of the knuckle directly affects the handling stability and safety of the vehicle. However, there are some problems in the design and use of traditional knuckles. During vehicle driving, especially in bad weather or when driving through water, the knuckle part is prone to water accumulation due to the splashing of road surface water. If this accumulated water cannot be drained in time, it may seep into components such as bearings inside the knuckle, resulting in corrosion and wear, thus affecting the performance and lifespan of the knuckle. In the existing knuckle design, the drainage efficiency is low, and it is difficult to effectively prevent water accumulation. When water accumulates between the knuckle and the bearing, it causes corrosion of the bearing. Therefore, in the prior art, drainage holes are generally provided on the bearing end face. Usually, the drainage holes adopt a cylindrical groove structure. During vehicle driving, it is approximately parallel to the road surface, and the slope is not large enough. Therefore, the drainage efficiency is low, and it is easy to accumulate water and block the bearing, resulting in corrosion. So, a new type of knuckle is needed to improve the deficiencies in the design. Content of the Utility Model

A shallow groove is provided on one side of the drainage groove. A number of bearing bolt installation holes are evenly spaced on the outer periphery of the bearing large hole. The knuckle body is installed on the automotive hub bearing through the bearing bolt installation holes. The drainage groove is designed as a conical semi-elliptical groove body to reduce water flow resistance; avoid water accumulation from affecting the lubrication and normal operation of the knuckle, ensure the accuracy and stability of the vehicle steering system, and ensure driving safety.
