Embodiment Construction

[0020] specific implementation

[0021] figure 1 , the pump actuator 1 is constructed as a dual-motor dual-clutch transmission. In the dual clutch transmission there are two sub-branches 2 , 3 , both of which comprise hydraulic cylinders 4 which actuate the clutch 5 . The respective hydraulic cylinder 4 of the clutch 5 is actuated via a dual-pressure valve 6 which is coupled to a pump actuator 7 . The two sub-branches 2 , 3 are connected to a transmission actuator 9 via a valve 8 .

[0022] Since the two sub-branches 2, 3 are constructed identically, only one sub-branch needs to be described. In each sub-branch 2 , 3 the line 10 is connected to a pump actuator 7 , which is driven by an electric motor 11 . The electric motor 11 is in turn driven by the control device 12 . Used to know the angular increment passed by the electric motor 11 The sensor 13 is arranged on the electric motor 11 . The switching signals of the sensor 13 are counted by a counter 14 arranged in th...

Abstract

The invention relates to a method for adjusting an operating point of a hydraulic actuator arrangement, in which a volumetric flow source is connected to a hydraulic cylinder (4) via a pressure line (10) which is filled with a hydraulic fluid, wherein a volume of the hydraulic fluid is regulated via the volumetric flow source (15) and the operating point corresponds to a position of the actuator arrangement (1) for a predefined parameter of a device (5) which is to be actuated by the actuator arrangement (1), wherein the volume of the hydraulic fluid which is required to adjust the operating point is derived from a rotational position of a volumetric flow source motor (11) and / or the volumetric flow source (15). In a method which facilitates a reliable start of the volume determination, avolume determination is started by means of a rotary angle regulation at a predefined pressure (p_K), wherein the predefined pressure (p_K) is lower than a system pressure (p_L).

Description

technical field [0001] The invention relates to a method for setting the operating point of a hydraulic actuator, wherein a volume flow source is connected to a hydraulic cylinder via a pressure line filled with hydraulic fluid, wherein the volume of the hydraulic fluid is regulated by the volume flow source and operated The point corresponds to the positioning of the execution facility under predetermined parameters of the device to be operated by the execution facility, wherein from the rotational position of the volume flow source motor and / or the volume flow source the required hydraulic fluid for setting the operating point is derived. volume. Background technique [0002] From WO 2016 / 141935 A1 a method for setting and adjusting the operating point of a hydraulic actuating device is known. Here, hydraulic actuation devices are used to actuate the clutch. The volume flow source, which is configured as a pump, is connected via a hydraulic line to a hydraulic cylinder, ...
