Cornay^® Company — A New C.V. Joint Technology

Reasons Cornay Technology delivers value and performance:

1. True constant velocity at all angles
2. Higher operating angles
3. Higher torque loads
4. No boot required
5. Higher RPMs
6. Lower weight
7. Longer service life
8. 65% less vibration
9. Service Free (Optional)
10. Significant system cost savings

How the Cornay C.V. joint works:

1. The internal coupling member creates a lower moment of inertia for much less vibration. The patented centering mechanism eliminates sliding friction.
2. The yoke members provide greater rigidity with less susceptibility to deflection and galled bearings.
3. Power is transferred via a ring-type bearing housing. The compact, concentric design permits high torque, high RPM capability at extremely high angles.
4. Adaptable to many vehicle flange configurations.

Existing Joint Limitations

Cardan-Style Universal Joint:
The Drawbacks of the Cardan-style universal joint (conceived in the late thirteenth century) are often overlooked. As the Cardan U-joint's operating angle goes up, its torque capacity, speed capacity and especially reliability decrease dramatically. Vibration is often a problem and failure due to inadequate lubrication is all too common.

Durability of single Cardan joints limit driveline angles to 6° or less. Double Cardan designs are limited to driveline applications below 12°.

Booted Constant Velocity Joints:
Booted style constant velocity joints have their problems too. Like the Cardan U-joint, their angle range is also limited. They cannot run at high angles and high speeds simultaneously. The booted style c.v. joints are also torque limited at high operating speeds and angles.

The most common maintenance issue is when the protective boot fails, resulting in lost lubricant, which means a joint failure is imminent.

True Constant Velocity —
Delivers Superior Performance

• The patented Cornay C.V. Joint centering device, allows the joint to work at true constant velocity at all angles.
• Designed specifically for high-speed, high-torque, high-angle applications that no existing joint could handle, the Cornay joint is unique design gives you major performance improvements in every area where traditional universal joints suffer weaknesses.
• Vibrations are decreased up to 65%, due to the concentrated mass of the connecting yoke.
• The Cornay C.V. Joint design dramatically increases longevity and reliability. Its unique channeled ring-type bearing housing maintains a constant supply of lubricant to all bearing surfaces and is completely purgeable. The result is the first universal joint that is truly maintenance free for life in many applications.
