Technical Advantages

Finite element analysis (FEA) optimizes the Wheel Hub Carrier’s geometry for uniform stress distribution. The design minimizes stress concentrations, reducing crack initiation risk under cyclic loads. Wheel Hub Carrier materials include high-strength forged alloys with tensile strengths exceeding 800 MPa. Controlled heat treatments improve fracture toughness and fatigue resistance in the Wheel Hub Carrier. This component must withstand multi-axial stresses from braking, cornering, and road shocks. The mechanical properties of the Wheel Hub Carrier are carefully controlled to extend service life under dynamic loading. 

Wheel Hub Carrier surfaces receive multi-layer corrosion protection starting with phosphate conversion coatings. Electro-deposited primers and powder coatings create a durable barrier against moisture and road salts. Material selection for the Wheel Hub Carrier minimizes galvanic corrosion when interfacing with different suspension metals. Salt spray and cyclic corrosion testing validate the coating performance on the Wheel Hub Carrier. These treatments maintain the structural integrity of the Wheel Hub Carrier in harsh environmental conditions. Effective corrosion resistance reduces maintenance and prolongs component reliability.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure the structural integrity of Wheel Hub Carriers under high dynamic loads?

Frigate uses finite element analysis (FEA) to simulate real-world stresses on Wheel Hub Carriers. This process identifies stress concentrations and optimizes the carrier’s design geometry. High-strength alloys are selected and heat-treated to enhance fatigue resistance. Quality checks verify that each carrier meets strict load-bearing requirements before shipment.

What quality control measures does Frigate implement for dimensional accuracy in Wheel Hub Carrier manufacturing?

Frigate employs coordinate measuring machines (CMM) to inspect every Wheel Hub Carrier for dimensional tolerances within ±0.01 mm. Statistical process control (SPC) monitors production consistency. All carriers undergo multiple inspections during and after machining. This ensures perfect fitment with suspension and braking assemblies. 

How does Frigate address corrosion challenges in Wheel Hub Carrier components?

Frigate applies multi-stage surface treatments including phosphate conversion and powder coating to the Wheel Hub Carrier. These coatings create protective barriers against moisture, salt, and chemicals. Material selection also reduces galvanic corrosion risks when interfacing with other metals. Accelerated corrosion tests validate long-term performance in harsh environments.

How does Frigate incorporate sensor integration into Wheel Hub Carrier production?

Frigate machines sensor mounting points with concentricity tolerances below 0.005 mm to ensure precise alignment. This allows accurate ABS and wheel speed sensor function. Electrical shielding features are designed into the carrier to minimize electromagnetic interference. Integration supports modern vehicle safety and control systems effectively.

What design features does Frigate use in Wheel Hub Carriers to improve vibration damping?

Frigate designs Wheel Hub Carriers with optimized ribbing and hollow sections to enhance structural damping. Modal analysis is conducted to avoid resonance frequencies that cause fatigue. High surface finish quality reduces micro-movements at bearing seats. These features extend the service life of both the carrier and connected suspension components.
