Complete production capabilities, versatile materials and customizable shapes for diverse applications.
Five key factors help ensure effective clutch cooling:
We select materials by analysing vehicle weight, speed and duty cycle to match the following operating conditions.
| Operating condition | Low | Medium | High |
|---|---|---|---|
| Normal pressure · MPa | 1 | 4 | > 8 |
| Energy absorption · J/cm² | 50 | 100 | > 160 |
| Oil flow rate · l/min/cm² | 0.003 | 0.009 | > 0.018 |
The type of oil has a significant effect on friction material performance.
Oil flow rate is one of the key factors affecting friction material service life.
HONVIGOR can design friction materials and groove patterns for the oil used in a specific application.
Groove geometry is essential for cooling the friction surface during engagement. Adequate cooling helps maintain a stable friction coefficient and prevents distortion of the clutch assembly. Cooling is necessary for efficient energy dissipation and even heat distribution across the mating steel plates. Different groove patterns affect parasitic losses, including drag torque. HONVIGOR engineers can select the most suitable groove pattern for your application.

| Property | Wet friction materials | Dry friction materials |
|---|---|---|
| Temperature limit | Limited by oil degradation | Up to material melting point |
| Static pressure | Up to 6.9 MPa | Up to 27.5 MPa |
| Friction coefficient | Approx. 0.1 | Approx. 0.4 |
| Heat dissipation | Depends on cooler and oil flow | Depends on cooler |
*Wet friction systems offer long service life, contamination resistance, spark-free operation, smooth engagement and low noise, and can also function as retarders with high power capability.
1. Define the process before selecting equipment: material, thickness, sheet size and monthly output determine power, table layout and capacity.
2. Request trials with your own material; paper specifications alone cannot establish cutting or pickling results.
3. Prioritize batch consistency, including gas control, automatic nozzle changing, synchronized drives and concentration/temperature interlocks.
4. Plan acid mist collection, acid regeneration, wastewater treatment, environmental review and access/emergency-stop management alongside the line.
5. Obtain complete technical documents, process settings, wear-parts lists, maintenance intervals and acceptance standards.
