Fuwa gasket

Functions

1. Axial Positioning and Support

• Limits axial movement of the camshaft to maintain precise valve timing, enhancing engine efficiency and performance.

• In Fuwa trailer brake systems, for example, the gasket prevents axial displacement of the camshaft under load, ensuring stable operation.

2. Sealing and Leak Prevention

• Fills microscopic gaps between the cylinder block and cylinder head to prevent air leakage from the combustion chamber and water leakage from the cooling jacket, ensuring coolant and oil integrity.

3. Vibration Damping and Noise Reduction

• Absorbs engine vibrations to improve smoothness and extend engine lifespan.

4. Lubrication Protection

• Features eccentric annular oil grooves (offset by 4mm) and radial straight oil slots, with grooves on both sides oriented 180° apart to lubricate and protect the entire mechanism, reducing dry friction.

Materials

1. Copper

• Commonly used for Fuwa camshaft thrust gaskets due to its excellent thermal conductivity and wear resistance. However, thin-walled copper components are prone to deformation, requiring strict process control during manufacturing.

2. Alloy Steel (Quenched)

• Some Fuwa camshaft gaskets are made of quenched alloy steel for enhanced hardness and wear resistance, suitable for high-load applications.

3. Non-Metallic Composite Materials

• Self-lubricating materials like PTFE (polytetrafluoroethylene) or graphite may be used for specific temperature or lubrication conditions.

Parameters

1. Structural Parameters

• Outer diameter:φ172mm(for thin-walled ring-type components)

• Inner diameter:φ90mm(process inner hole size for clamping during machining)

• Parallelism requirement:0.02mm(parallelism between the two flat surfaces)

2. Machining Tolerances

• Thickness tolerance:4 ± 0.03mm(copper components are sensitive to temperature changes, requiring tight tolerance control)

• Groove depth tolerance: During rough machining, the product thickness tolerance is set to(5 ± 0.1)mmto ensure the groove depth meets drawing requirements.

3. Compatible Vehicle Models

• Fuwa trailer semi-trailers, United Heavy Truck Fuwa 470/510/330 rear brake systems, etc.

Applications

1. Fuwa Trailer Brake Systems

• Used for axial positioning and sealing of the camshaft in Fuwa trailer brake systems, preventing air and water leaks to ensure braking performance.

2. Heavy-Duty Truck Engine Camshaft Support

• Applied in engines of United Heavy Truck Fuwa 470/510/330 models for axial positioning of the camshaft, ensuring precise valve timing.

3. High-Load Industrial Machinery

• Quenched alloy steel gaskets are suitable for high-wear and high-strength scenarios, such as camshaft support in heavy-duty machinery.

Notes

• For exact compatibility with Fuwa components, refer to the official product catalog or contact a certified supplier.

• Ensure proper installation (e.g., avoiding over-tightening, using recommended torque values) to maximize performance and longevity.
