Method for testing function of dual clutch assembly

Abstract

The invention relates to a method for testing the function of a dual clutch assembly (100) by means of a test unit (200) and a drive motor (300). The dual clutch assembly (100) includes two friction clutches (120, 140) connected with a common cooling oil joint, a detection unit (200) has two detection shafts (220, 240), pressure oil sources, and cooling oil sources provided with corresponding insert tooth parts and connected with torque measurement devices (222, 242), and the drive motor (300) is coupled to an clutch input shaft (150). The method includes the following steps that in the setting step, the dual clutch assembly (100) sleeves on the insert tooth parts of the detection shafts (220, 240) and oil sources are connected with the corresponding oil joints, and the drive motor (300) is connected with the clutch input shaft (150), and testing is carried out. The method for testing the function of the dual clutch assembly is characterized in that during the setting step, the dual clutch assembly (100) orientedly sleeves on the insert tooth parts of the vertically oriented detection shafts (220, 240) in a vertical axial direction, and then the test unit (200) and the sleeved dual clutch assembly (100) are inclined to the horizontal axial direction for orientation.

Description

technical field [0001] The invention relates to a method for functional testing of a double clutch unit by means of a testing unit and a drive motor, wherein [0002] - the dual clutch unit comprises two friction clutches connected to a common cooling oil connection, each having an adjustment mechanism connected to a hydraulic pressure oil connection and a set of inner friction plates and a set of outer friction plates , wherein the outer friction plates are connected to the common clutch input shaft through their respective outer friction plate brackets, and the inner friction plates can be respectively connected to the corresponding plug-in The outer shaft of the tooth portion is connected, [0003] - the detection unit has two detection shafts provided with such corresponding splines and connected to a torque measuring device, a pressure oil source connectable to the pressure oil connection and a connection to the cooling oil connected cooling oil source, and [0004] - ...

Problems solved by technology

However, the dual clutch unit is therefore very complex to fit on the test shaft, since the unclamped inner disks in the disk pack can slip and tilt in the region of their gaps due to the influence of gravity

Correspondingly, the packaging process must be carried out carefully, which can only be carried out manually with a high expenditure of time or at the expense of additional sensors.
