Definitions
- the present invention relates to an actuator for actuating a clutch and a clutch for a motor vehicle with a corresponding actuator.
- a clutch is engageable and disengageable to interrupt a torque flow from a drive motor to a drive train of a motor vehicle.
- actuating systems which have at least one actuator.
- the at least one actuator can be, for example, a master cylinder or slave cylinder, which can also be connected to one another via a hydraulic line.
- master cylinder with a measuring sensor to monitor the path of a master cylinder piston and thereby the clutch actuation.
- targets are used in the prior art, which are integrated into the master cylinder. A disadvantage of these targets is the cost, the necessary calibration and the sensitivity to certain temperatures and interference fields.
- displacement sensors on a master cylinder can not detect whether the clutch is actuated, so that in the event of a malfunction of the actuation system, for example due to leakage, errors can occur.
- displacement sensors on the slave cylinder could not prevail because of the prevailing difficult ambient conditions, for example ambient temperatures of more than 200 ° C., dirt and / or water entry.
- the object of the invention is therefore to solve the problems described with reference to the prior art, at least partially and in particular to provide an actuator for actuating a clutch, with which an actuation of the clutch is reliably recognizable.
- a coupling for a motor vehicle should also be specified, with the actuator of which actuation of the coupling can be reliably recognized.
- the actuator according to the invention for actuating a clutch has a housing with a pressure chamber, wherein in the pressure chamber, a piston is movably arranged and wherein the actuator has a semiconductor pressure sensor, with which a pressure in the pressure chamber can be determined.
- the actuator proposed here is, in particular, a master cylinder or slave cylinder of an actuating system of a clutch.
- the actuator is used to engage and disengage the clutch.
- the coupling is in particular a friction clutch, for example in the manner of a double clutch.
- the actuator has a housing which, for example, at least partially made of plastic and / or metal.
- a pressure chamber is formed, in which a piston is movable.
- a master cylinder of the piston for example, by a clutch pedal or an electric motor in the pressure chamber movable, whereby an actuating fluid in the pressure chamber through the piston via a hydraulic line for actuating the clutch is fed to a slave cylinder.
- the piston is movable by the actuating fluid in the pressure chamber.
- the actuating fluid has different pressures in the pressure chamber depending on the operating situation of the actuator.
- the actuator has a semiconductor pressure sensor.
- the semiconductor pressure sensor consists at least partially of silicon and works in particular according to the piezoresistive principle.
- the semiconductor pressure sensor in particular has a membrane which is etched out in particular from the silicon. With the semiconductor pressure sensor pressures of preferably up to 50 bar, more preferably up to 100 bar can be determined.
- the pressure determined by the semiconductor pressure sensor can in particular be assigned to a position of the piston in the pressure chamber, so that a pressure-displacement characteristic can be determined. This can be checked for plausibility and in the case of deviations, for example, by a leak or air in the Actuation system, early warning of a driver of the motor vehicle.
- the actuator has a displacement sensor for determining a position of the piston in the pressure chamber.
- the actuator is provided in particular with a so-called target, which is in particular a magnet.
- the displacement sensor is therefore an inductive displacement sensor.
- a circuit board is arranged on the housing, on which the semiconductor pressure sensor is integrated. In other words, this means that the semiconductor pressure sensor is arranged directly on and / or in the circuit board.
- the circuit board is a printed circuit board, which in particular represents a carrier for electronic components.
- the semiconductor pressure sensor can be fixed in the housing by a cover cap.
- the cap is at least partially made of plastic and / or metal.
- the semiconductor pressure sensor is connected via a connecting piece to the pressure chamber.
- the connecting piece is a pipe piece to which the semiconductor pressure sensor can be connected in particular.
- a warning signal for a driver of a motor vehicle can be activated by the semiconductor pressure sensor if an actual measured value of the pressure deviates from a nominal measured value of the pressure or of a predetermined nominal pressure range.
- a seal seals the semiconductor pressure sensor to the housing.
- the seal is in particular an O-ring.
- a clutch for a motor vehicle is also specified, wherein the clutch can be actuated by an actuator according to the invention.
- the coupling is in particular a (dry or wet) friction clutch, for example in the manner of a double clutch.
- FIGS. show particularly preferred embodiments of the invention, but this is not limited thereto.
- the same components are provided in the figures with the same reference numerals. They show schematically:
- Fig. 1 a coupling with an actuator
- Fig. 2 a torque-displacement curve and pressure-displacement curve.
- the actuator 1 shows schematically a coupling 2 with an actuator.
- the actuator 1 is designed here in the manner of a master cylinder and has a housing 3 with a pressure chamber 4.
- a piston 5 is movable in an axial direction 12 of the actuator 1.
- an actuating fluid can be pressed by the piston 5 in the pressure chamber 4 through the piston 5 to a slave cylinder, not shown here, whereby the actuating fluid has different pressures in different positions of the piston 5 in the pressure chamber 4.
