Clutch Disc

 

We have developed over 700 models clutch disc assembly, diameter range from 160mm to 430mm, application covering all kinds of commercial vehicles clutch disc, passenger cars clutch disc and tractors clutch disc, our main products including clutch disc assembly for auto type: Volvo truck, Mercedes Benz truck, Scania, Man, Renault, Fiat, Skoda, Iveco, Howo, Ford, Buick, Chevrolet, Cat, and all kinds of  Korean and Japanese vehicles like Hyundai, Daewoo, Mitsubishi, Hino, Isuzu.

We have invested advanced toolings technology from abroad, with CAD and CAM technology, our yearly production ability is two million sets.  

According to the Automobile Dry Clutch Disc Assembly Bench Test Technique and Automobile Dry Clutch Disc Assembly Technology Qualification, our clutch disc assembly products were tested and the results showed as follows: 

1, Overspeed test: Continuously accelerating clutch disc assembly rotation speed to 8000 RPM at 250, and keep speed for 5 Mins, no crack and damage on the clutch disc assembly.

2, Fatigue test: The clutch disc assembly maximum torque not less than 75% of primary data, after a 3.5x 106 recycle, friction damp torque not less than 60% of primary data;

3, Temperature increase test: Start the clutch disc assembly 10 times, the average temperature less than 10.

4, Dynamic friction torque test: After clutch disc assembly mating with the work surface, when contact surface over 80% at 1500 RPM, force friction disc slip to friction surface to 250, the clutch disc assembly unit dynamic friction torque not less than 0.3NM/CM2. The dynamic friction torque at 250 not lower than 70% of value at room temperature.

5, Friction facing wearing rate test: After clutch disc assembly mating with the work surface, when contact surface over 80% at 1500 RPM, running the clutch disc assembly 1x104 times, the friction surface wear rate not over 0.65mm, no crack, no bubble and no rivets exposed.
