Embodiment Construction

[0023] figure 1 is an exemplary embodiment of a hydraulic clutch actuator 1 according to the invention for use, for example, in a motor vehicle drive train, wherein the hydraulic clutch actuator 1 is used to actuate a clutch arrangement 2 . A volumetric flow source, designed for example as a pump 3 , is connected via a high-pressure hydraulic line 4 to a hydraulic cylinder 5 , which acts on the clutch device 2 via an engagement bearing 6 . The hydraulic fluid is sucked out of the hydraulic fluid tank 7 by the pump 3 through the low-pressure hydraulic line 8 , passed through the pump 3 , and delivered to the hydraulic cylinder 5 through the high-pressure hydraulic line 4 . The hydraulic fluid moves the piston of the hydraulic cylinder 5 whereby the engagement bearing 6 is moved and the clutch 2 is also moved.

[0024] The pump 3 is driven by the motor 9, and an angle sensor 10 is positioned on the motor 9 to measure the rotation angle of the motor 9. The rotational position ...

Abstract

The invention relates to a method for adjusting and adapting the operating point of a hydraulic actuator, wherein a volume flow source (3) is connected to a hydraulic cylinder (5) via a pressure line (4) filled with hydraulic fluid, wherein, The volume (V) of the hydraulic fluid is regulated by the volume flow source (3), and the operating point of the position of the actuator (1) is under predetermined parameters and the device to be operated by the actuator (1) (2) match. In a method in which the amount of calculation is reduced, the rotational position of the motor (9) is determined by the volume flow source and / or the rotational position of the volume flow source (3) Derive the volume of the hydraulic fluid required to adjust the operating point (V ist neu ).

Description

technical field [0001] The invention relates to a method for adjusting and adapting the working point of a hydraulic actuator, wherein a source of volume flow is connected to a hydraulic cylinder via a pressure line filled with hydraulic fluid, wherein the volume of hydraulic fluid is controlled by the source of volume flow adjustment, and the operating point of the position of the actuator is adapted to the device to be actuated by the actuator within predetermined parameters. Furthermore, a method of operation of a clutch of a drive train of a motor vehicle, and a hydraulic actuator are devised. Background technique [0002] Hydraulic actuators are widely used, especially in motor vehicles. It can thus be used for the actuation of friction clutches or for automatic shifting of automatic transmissions. In this case, such hydraulic actuators have a defined operating point in the form of a position in which the gear is engaged or from which the clutch starts to transmit the...
