2 Clutch and release system transmission speeds, the clutch torque as a function of the pedal travel can be varied to best suit each and every driving condition. LuK has already installed CBW prototypes in several different vehicles and tested them. The launch performance has improved remarkably compared to conventional clutch systems as a result of the function just described. Summary Despite the large number of technical solutions presented here, the application areas of the different concepts can be clearly defined. The controlling parameters are the maximum engine torque and the desired maximum pedal load as shown in Figure 32. This should be viewed as a recommendation, which can vary depending on the philosophy of the vehicle manufacturer. Smaller steps can be achieved through the separate optimization of individual components. The Figure 32 Options and potential for reducing operating load correct technical solutions for the torque increases of the coming years can only be found with the correct dimensioning of the complete system. The complexity of the solutions for high torque applications may appear high at first. However, if the intension is to offer manual transmissions in this class, there is no alternative but to start with the total system development as soon as possible. In order to support this, LuK has put the prerequisites in place with a complete switch from a component supplier to a system supplier. This requires close cooperation between the clutch and chassis departments at the automobile manufacturers. Together with the automobile manufacturers, LuK will continue to present innovative solutions, which offer the end consumer optimal operating comfort despite significantly increased engine torques. 44 LuK SYMPOSIUM 2006
