Definitions
- the invention relates to a hybrid module for a drive train of a motor vehicle, having a dual clutch having a first partial clutch (K1) and a second partial clutch (K2) for selectively transmitting torque of a first drive unit, in particular an electric machine, to an output shaft, and a separating clutch (K0) for coupling a second drive unit, in particular an internal combustion engine, to the drive train and for transmitting torque of the second drive unit to the output shaft.
- K1 first partial clutch
- K2 a second partial clutch
- K0 for coupling a second drive unit, in particular an internal combustion engine
- WO 2017/088869 A1 discloses a hybrid module for a motor vehicle for coupling an internal combustion engine, having a separating clutch by means of which the internal combustion engine can be separated from a drive train of the motor vehicle and by means of which torque can be brought from the internal combustion engine to the drive train an electric motor connectable to the driveline for torque transmission via a master clutch, a disconnect clutch actuation system for actuating actuation of the disconnect clutch and a main clutch actuation system for actuating actuation of the main clutch, characterized in that both actuation systems are interposed between the disconnect clutch and the main clutch are arranged.
- a hybrid module is known inter alia from the non-prepublished application DE 10 2017 104 487. This discloses a hybrid module for a drive train of a motor vehicle, having a stator and a rotor having an electric machine, a torsion part having at least one torsional vibration damper, and an integrated and formed as a double clutch coupling a rotor receiving rotor carrier is connected directly via a permanent rotational connection with the at least one rotary member, wherein the rotor carrier forms a coupling component of at least one partial coupling of the coupling device.
- an improved hybrid module is to be developed, which is able to transmit high actuating forces for actuating the couplings, and at the same time space-optimized and inexpensive to produce.
- the object of the invention is achieved in a generic device according to the invention that in the hybrid module at least one rotary feedthrough is provided, on the one hand for guiding actuating oil, which is designed for actuating the separating clutch, or on the other hand is designed for guiding cooling oil, for cooling the separating clutch and / or the double clutch is designed.
- a rotary feedthrough for guiding actuating oil which is designed for actuating the separating clutch, the first partial clutch and / or the second partial clutch, is present both for the separating clutch and for the first partial clutch and the second partial clutch.
- the rotary feedthrough for guiding actuating oil for actuating the separating clutch in a housing and a rotor flange which is fixedly connected to a rotor carrier for supporting the first drive unit is formed.
- the rotary feedthrough can be implemented integrally in existing components without far-reaching structural changes.
- the rotor flange has a receptacle for a rotor position sensor which is designed to indicate the position of the rotor when detected by a rotor position sensor.
- the rotor flange can be used to support the actuating forces of the first part clutch.
- the separating clutch is designed as a multi-disc clutch, wherein an inner disc carrier or an outer disc carrier is firmly connected to the rotor flange.
- the power flow of the actuating forces can thereby be designed to be self-contained.
- the other of the inner disk carrier and the outer disk carrier prefferably be connected to the second drive unit in order to enable torque transmission.
- at least one oil-filled centrifugal oil compensation space is present, which is configured such that the oil pressure in the centrifugal oil compensation space exerts a force in the axial direction on one for actuating the separating clutch, the first partial clutch and / or the second partial clutch axially displaceable actuator applies, which counteracts an actuating force of the actuating oil for actuating the separating clutch, the first part clutch and / or the second part clutch.
- the oil pressure in the centrifugal oil compensating space corresponds to an operating oil pressure in a pressure space filled with actuating oil for operating the separating clutch, the first part-coupling and / or the second part-coupling.
- actuating oil for operating the separating clutch, the first part-coupling and / or the second part-coupling.
- the rotary leadthrough for guiding actuating oil for actuating the separating clutch is formed by a through hole in the rotor flange, which is connected via a radially circumferential groove to an actuating oil feed in the housing. Since the rotor flange rotates relative to the housing, it is necessary to form on one of the two components a circumferential groove, so that the through hole in the rotor flange is connected in any rotational position via the groove with the actuating oil supply in the housing.
- the groove is connected via a through hole in a sleeve with the actuating oil supply in the housing.
- the actuating oil can be guided by the housing through a housing interior, since the Sleeve which serves as a seal carrier, the actuating oil supply seals against the housing interior.
- a counterpressure element for supporting an actuating force for actuating the separating clutch, the first partial clutch and / or the second partial clutch is fixedly connected to the rotor flange.
- the counter-pressure element is designed to support the actuating force of the separating clutch as a support screw, retaining ring or bayonet ring.
- Clutch carrier of the clutch on a support bearing is supported, and when the actuating forces that arise when operating the clutch, via an actuator, the clutch and the clutch carrier in self-contained run so that the operating forces bypass the support bearing.
- the first and the second rolling bearing may be designed as needle bearings.
- a counterpressure element for clutch discs is present when the disconnect clutch is actuated, which is designed to receive the actuating forces and which is connected to the clutch carrier, such as an inner disc carrier or an outer disc carrier.
- the counter-pressure element is designed as a support screw, a retaining ring or a bayonet ring.
- the counter-pressure element can be produced inexpensively and at the same time perform the function of a counter-pressure plate for supporting the actuating forces.
- a favorable embodiment is characterized in that the counter-pressure element is connected via a toothing with the coupling carrier.
- an external toothing is formed on the counterpressure element and an internal toothing is formed on the coupling carrier, for example the inner plate carrier.
- the counterpressure element can be connected in a rotationally fixed manner to the coupling carrier.
- the counter-pressure element is designed and arranged such that it defines the support bearing in the axial direction.
- the counter-pressure element thus simultaneously serves as an axial stop for the support bearing, so that advantageously fewer components have to be used.
- the actuation forces are supported by the separating clutch via the counter-pressure element on a rotor flange fixedly connected to the coupling carrier, so that the force flow of the actuating forces is self-contained and the housing bypasses.
- the actuating forces must therefore not be supported by the rotating components, such as the clutch carrier, the rotor flange or the counter-pressure element on the support bearing on the housing, since the actuator for actuating the separating clutch is not mounted in the housing, but in the rotor flange.
- a rotary leadthrough for guiding actuating oil which is designed to actuate the separating clutch, is present in the rotor flange is. This allows the actuator to be placed in the rotor flange rather than a conventional slave cylinder in the housing, with the actuating force applied via an actuator bearing.
- the power flow of the actuating forces is thus advantageously closed in itself, so that the actuating forces are supported on firmly connected to the rotor flange components.
- the rotor flange is slidably mounted in the region of the rotary feedthrough for actuating the separating clutch. As a result, it is advantageously possible to ensure a supply of fluid from the housing into the rotating rotor flange.
