Chapter 6
How Steering Knuckles Are Manufactured
The manufacturing of a steering knuckle is a meticulous process that combines precision engineering with robust materials to ensure durability and reliability. Here’s a detailed look at the typical steps involved in manufacturing a steering knuckle:
Casting or Forging
Once the design is finalized, the material is selected based on the required strength and durability. The initial shape of the steering knuckle is typically formed through one of two primary methods:
Casting: In this method, molten metal is poured into a mold that shapes the steering knuckle. This process is suitable for producing complex geometries and is cost-effective for large-scale production.
Forging: Alternatively, forging involves shaping the metal using compressive forces, usually by hammering or pressing. Forged steering knuckles are generally stronger and more durable than cast ones due to the refined grain structure.
Machining Process
After the basic shape is formed, machining processes refine the steering knuckle to precise dimensions. CNC (Computer Numerical Control) machines are often used to ensure accuracy and consistency. This step involves:
- Milling: Removing excess material to achieve the desired contours and dimensions.
- Drilling: Creating holes for mounting points and other necessary openings.
- Turning: Shaping round surfaces such as bearing seats.
Heat Treatment
To enhance the mechanical properties, the steering knuckle undergoes heat treatment processes like quenching and tempering. These processes increase the hardness and strength of the metal, making it more resistant to wear and impact.
Surface Finishing
- Shot blasting: Using small steel balls to clean the surface and improve fatigue resistance.
- Polishing: Enhancing the surface smoothness and appearance.
Quality Inspection
- Dimensional checks: Using precision instruments to measure and verify dimensions.
- Non-destructive testing (NDT): Techniques like X-ray or ultrasonic testing to detect internal defects without damaging the part.
Assembly and Final Testing
- Load testing: Applying forces to simulate the stresses experienced during vehicle operation.
- Durability testing: Repeatedly testing the part to ensure it can withstand long-term use.
Coating and Packaging
Finally, the steering knuckle is coated with protective layers to prevent corrosion and enhance durability. It is then packaged carefully to prevent damage during transportation.
Chapter 7
Common connection of Steering Knuckle
Steering knuckle is the critical component of the vehicle which is linked with suspension system. It allows steering arm to turn the front wheel and it also supports the vertical weight of the vehicle. The steering knuckle is the connection between stub axle, tie rod and axle housing with the help of using king pin, and these are also connected to the suspension system . In this, wheel hub is fixed with steering knuckle with the help of bearing. The main function of steering knuckle is to convert linear motion of the tie rod into the angular motion of the stub axle . In the automobile industry, the requirement of properties of steering knuckle is that it must be strong, inflexible and light as well as possible. When steering is turn by drivers, half portion of the steering knuckle component is subjected to tensile load and another half portion of steering knuckle component is subjected to compressive load and due to this rotation of wheel, steering knuckle is subjected to torsional load.
The part of steering knuckle component are given below:
- Suspension Mounting Upper Arm/Strut Mount
- Tie Rod Mounting / Steering Arm
- Lower Ball Joint /Suspension Mounting Lower Arm
- Ball Bearing Location / Stub Hole
- Brake Caliper Mounting
The shape and size of steering knuckle component depends upon the vehicle weight because vertical load of the vehicle is directly act on it and hence the steering knuckle component.
subjected to power thrust from tie rod to the stub axle and hence it must be strong and inflexible in nature. The steering knuckle in the automobile industry can be made either by forging or from casting. However, castings have blown-holes which are injurious from fatigue and durability points of view. The fact that forgings produce blow-hole free and good parts give them an advantage over cast parts. Due to large volume production of steering knuckle component, it is only logical that optimization of the steering knuckle for its volume or weight should be result in large-scale saving. The reduction of inertia load, torsional load, vehicle weight will improve the vehicle performance and fuel economy.
