Abstract
An actuator arrangement for a motor vehicle drivetrain, in particular for a dual-clutch arrangement. A first fluid cylinder is connected via a first fluid connection to a fluid supply device. A second fluid cylinder is connected via a second fluid connection to the fluid supply device. A pressure measuring arrangement has a single pressure sensor which is connected by means of a connecting arrangement to the first fluid connection and to the second fluid connection.
Claims11
An actuator arrangement for a motor vehicle drivetrain, having a first fluid cylinder which is connected via a first fluid connection to a fluid supply device, having a second fluid cylinder which is connected via a second fluid connection to the fluid supply device, and having a pressure measuring arrangement;
- wherein the pressure measuring arrangement has a single pressure sensor which is connected by means of a connecting arrangement to the first fluid connection and to the second fluid connection, wherein the connecting arrangement has a valve arrangement, wherein the valve arrangement is connected to the first and second fluid connections and to the pressure sensor such that the pressure sensor detects the minimum pressure out of fluid pressures prevailing in the fluid connections, and wherein the valve arrangement is fluid-actuated.
A dual clutch arrangement, having a first clutch, a second clutch and an actuator arrangement, the actuator arrangement having a first fluid cylinder which is adapted to actuate the first clutch and is connected via a first fluid connection to a fluid supply device, having a second fluid cylinder which is adapted to actuate the second clutch and is connected via a second fluid connection to the fluid supply device, and having a pressure measuring arrangement;
- wherein the pressure measuring arrangement has a single pressure sensor which is connected by means of a valve arrangement to the first fluid connection and to the second fluid connection, and which the single pressure sensor detects the minimum pressure out of fluid pressures prevailing in the fluid connections, and wherein the valve arrangement is fluid-actuated.
A method for the control of a dual-clutch arrangement by means of an actuator arrangement, the dual clutch arrangement having a first clutch and a second clutch, and the actuator arrangement having a first fluid cylinder which is adapted to actuate the first clutch and is connected via a first fluid connection to a fluid supply device, having a second fluid cylinder which is adapted to actuate the second clutch and is connected via a second fluid connection to the fluid supply device, and having a pressure measuring arrangement;
- wherein the pressure measuring arrangement has a single pressure sensor which is connected by means of a valve arrangement to the first fluid connection and to the second fluid connection, wherein the method includes the step of detecting the minimum pressure out of the fluid pressures in the fluid connections, and wherein the valve arrangement is fluid-actuated.
