Abstract
Description
Technical Field
[0001] The utility model relates to the field of automobile parts, in particular to an automobile steering knuckle. Background Art
[0002] In the modern automotive industry, the car steering knuckle is a key component of the car's steering system. It connects the wheels and the steering mechanism and is responsible for converting the driver's steering input into changes in the direction of the wheels. However, existing car steering knuckles are prone to wear when subjected to high-frequency steering operations. At the same time, the locking mechanism may not be reliable enough, causing the components to loosen during vehicle operation. In modern industrial design and manufacturing, improving the friction and connection stability of mechanical parts is a key factor in ensuring the efficient and stable operation of mechanical systems. Traditional design methods often rely on the hardness of the material, surface treatment and the preload of the fasteners to achieve this, but with the development of technology, a more innovative and effective method - processing special knife-shaped structures on the surface of parts - has gradually become a new trend in improving mechanical performance. Utility Model Content
