XTend® - Clutch Cover with Automatic Wear Compensation
The Clutch Cover with Automatic Wear Compensation
The clutch cover transmits engine torque via the clutch disc to the transmission input shaft. There is a variety of clutches with diaphragm spring for passenger cars. As clutch facings are subject to normal wear, the longer they are used the greater their actuation forces needed on the clutch covers and therefore the greater the pedal forces. With XTend®, this problem is solved by decoupling the wear on the facing
Advantages
- Constant pedal forces throughout the entire service life
- Flexible adjustment to individual vehicle requirements
- Resistance to extreme temperatures, dirt, and aging
- Smaller axial dimensions
- Easy to install and service
Product Details
The task
Although clutch facings have undergone substantial improvement in terms of quality and service life, they are still subject to normal wear, even if the vehicle is operated with care. Reduced facing thickness considerably influences the forces within the clutch system. Release and clamp loads rise, and thus the necessary pedal forces as well. XTend® is the ideal solution to counter wear and the associated negative effects on the powertrain. XTend® clutch covers are suitable for all vehicles with high mileage and clutch loads.
The technology:
XTend®, the clutch cover with automatic wear compensation, decouples facing wear from the movement of the diaphragm spring. The compensation mechanism constantly registers the reduction in facing thickness, and securely offsets this distance by rotating an adjustment ring. This keeps the force ratios constant, and extends the service life because the facings can accomodate additional wear. Another advantage of XTend® lies in its design: It reduces the axial dimensions of the clutch system needed to accomodate normal facing wear.
