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 an operating point of a hydraulic actuator arrangement, in which invention a volume flow source (3) is connected to a hydraulic cylinder (5) via a pressure line (4) which is filled with a hydraulic fluid, wherein a volume (V) of the hydraulic fluid is regulated by means of the volume flow source (3), and the operating point of a position of the actuator arrangement (1) corresponds, with respect to a predefined parameter, to a device (2) which is to be activated by the actuator arrangement (1). In a method in which computer capacity is reduced, the volume (Vact new) of the hydraulic fluid which is necessary to adjust the operating point is derived from a rotational position (Phi) of a volume flow source motor (9) and / or of the volume flow source (3).

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 operating a clutch of a drive train of a motor vehicle according to claim 8 and a hydraulic actuator according to claim 10 are envisaged. 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 fro...
