A multi-plate friction assembly within an automatic transmission that engages and disengages power flow between rotating components.
Technical details and manufacturing context for Clutch Pack
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Outer Diameter | 150–300 mm | Determines fit with transmission housing |
| Inner Diameter | 100–200 mm | Matches shaft spline |
| Number of Plates | 4–10 pcs | Affects torque capacity |
| Friction Coefficient | 0.08–0.12 | Wet clutch with ATFASTM D1894 |
| Dynamic Torque Capacity | 200–600 N·m | Must exceed engine torque |
| Max Operating Temperature | 120–150 °C | Above this causes glazing |
| Surface Flatness | ≤0.05 mm | Ensures even pressure distributionISO 1101 |
| Surface Roughness | 0.4–0.8 μm Ra | Affects friction stabilityISO 4287 |
| Weight | 1.5–3.5 kg | Influences rotational inertia |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
| pressure: | Up to 20 bar hydraulic actuation pressure, 0-15 bar clutch apply pressure |
| other spec: | Maximum slip speed: 5000 RPM differential, Torque capacity: 50-800 Nm depending on plate count and diameter |
| temperature: | -40°C to 150°C (operating), up to 200°C (peak transient) |

Explore company information and manufacturing capabilities, then discuss the scope of your project with a relevant supplier.
Ask for use case, specification boundaries, supplier type, and RFQ preparation information for this product.
A clutch pack selectively connects or disconnects power flow between rotating components, enabling smooth gear shifts by locking or releasing alternating friction and steel plates via hydraulic pressure.
Common materials include sintered bronze/copper friction material for the friction plates, high-carbon steel for separator plates, and steel for the housing and piston.
Check the outer and inner diameters, number of plates, and torque capacity against your transmission's specifications. Always confirm with the legal manufacturer or supplier, as values are reference ranges.
Symptoms include slipping during gear changes, delayed engagement, or overheating. If operating temperature exceeds 150°C or pressure is outside 1.0–1.6 MPa, inspect the pack for glazing or wear.
