The steering knuckle, as the core component of the automotive suspension system, connects the wheels and axles and carries important functions. According to different characteristics, steering knuckles can be subdivided into the following categories:

1. Material classification:

a. Steel steering knuckle: widely used, high strength, extremely durable.

b. Aluminum alloy steering knuckle: It has the advantage of lightweight and helps improve fuel efficiency, but the cost is relatively high.

c. Plastic or composite steering knuckles: lighter in weight and lower in cost, but slightly weaker in strength compared to other materials.

2. Structural classification:

a. Integrated steering knuckle: easy to manufacture and install, simple and clear structure, low cost.

b. Separated steering knuckle: The upper and lower parts are manufactured separately and then combined through connectors, making this structure easy to maintain and replace.

3. Classification of driving modes:

a. Front wheel drive steering knuckle: responsible for transmitting power from the front gearbox to the drive wheels.

b. Rear wheel drive steering knuckle: mainly supports the weight of the vehicle and transmits braking force.

c. Steering knuckle for four-wheel drive models: It needs to meet the requirements of front and rear drive and braking, with more comprehensive functions.

4. Vehicle classification:

Different car models such as sedans SUV�� Trucks and other vehicles may use different types of steering knuckles based on their characteristics and requirements. These steering knuckles will be adjusted in design and function to better adapt to the needs of different vehicle models.
