traction unit for motor vehicle and method for determining the characteristic of a traction unit coupling

摘要

ENGINE VEHICLE DRIVE AND METHOD FOR DETERMINING THE FEATURE OF A DRIVE COUPLING The present invention relates to a traction unit for a motor vehicle, comprising at least one drive motor (1) with a drive shaft. output, a transmission (9), which has an input shaft and at least one idler shaft (11) with an idler shaft brake (17), a friction clutch (3) with a first friction element connected to the shaft and a second friction element connected to the input shaft, a clutch operating mechanism (15) for friction clutch engagement and disengagement (3), an electronic control unit (12) for operating mechanism control (15) depending on various control parameters, and a position detector (18), which detects the position of the clutch operating mechanism (15) and transmits a position-dependent signal. to the control unit (12). A torque transmitter is provided which detects torque on the input shaft (7) and transmits a torque dependent signal to the control unit (12), and that the control unit (12) is arranged so that , on predetermined occasions, when the transmission (9) is in a neutral position and the intermediate shaft brake (17) is applied gradually to change the degree of friction clutch gear (3) and to record and store, As a function of the position of the clutch operating mechanism (15), the torque measured by the torque transmitter (19).
