Abstract

A torque transmitting device in a drive train of a vehicle, which has an assembly on the engine side and an assembly on the transmission side. A geometrically defined installation position of the torque transmitting device between the assemblies can be set by inserting a compensating element, such as an adjustment disk. A thickness of the compensating element depends on the air gap of the torque transmitting device to be set.

Claims (10)

1. A method for mounting a torque transmission device in a drive train of a vehicle having an engine side structural group on an engine side and a gear unit side structural group on a gear unit side, comprising the following steps:

assembling the torque transmission device;

determining an actual air gap in an assembled state of the torque transmission device, wherein the actual air gap is a function of construction component tolerances;

determining a desired thickness of a compensating element in dependence on the determined actual air gap in comparison to a desired air gap, the compensating element being a separate exchangeable element disposable at one of the engine side structural croup and the gear side structural group;

recording an information about a thickness of the compensating element determined in this manner, the information being separate from the compensating element, the step of recording comprising one of marking the information as plain text or coded description on the torque transmission device, and delivering the information together with the clutch; and

wherein the torque transmission device is supplied separately without the compensating element during a manufacture of the vehicle, and that during the manufacture of the vehicle, when mounting the torque transmission device in a drive train of a vehicle, the method comprises reading out the recorded information and selecting a compensating element haying the thickness corresponding to the read recorded information provided on the respective torque transmission device during the assembly of the torque transmission device.

2. The method according to claim 1 , wherein an air gap of the torque transmission device is classified into classes, and wherein a nominal compensating element thickness is assigned to each of the classes.

3. The method according to claim 2 , wherein the information indicates the nominal compensating element thickness.

4. The method according to claim 3 , wherein the information for the nominal compensating element thickness is read out during the assembly of the of the torque transmission device and is further processed, so that an appropriate correction of the actual air gap can be carried out.

5. The method according to claim 1 , wherein the compensating element is an adjusting disk.
