Definitions

  • the invention relates to a hybrid module for a (hybrid) drive train of a motor vehicle, having a housing, an input shaft mounted in the housing for introducing a torque generated by a first drive machine, a rotor carrier for introducing a torque generated by a second drive machine, a disconnect clutch for the switchable rotary coupling of the input shaft to the rotor carrier, a coupling for the rotary coupling of the rotor carrier with an output shaft, with a hydraulic actuation system for actuating the separating clutch, the actuation system including an actuation cylinder and an actuation piston which is axially displaceably received in the actuation cylinder, with one Return spring for applying a return force counteracting the actuating force of the actuating piston, and with a compensation chamber for receiving hydraulic fluid to compensate for an actuation generated by the centrifugal force force of the actuating piston.
  • Hybrid modules are already known from the prior art.
  • DE 10 2009 059 944 A1 discloses a hybrid module for a drive train of a vehicle, with a first clutch, an electric motor and a second clutch, the first clutch in the torque flow between an internal combustion engine in the drive train and the electric motor and the second clutch is arranged in the torque flow between the electric motor and a transmission in the drive train, the first clutch and the second clutch are arranged in a common wet room.
  • a clutch system for motor vehicle drives with at least one clutch input and at least two transmission input shafts, each transmission input shaft being connected to the clutch input via a separate liquid-cooled and lubricated friction clutch, wherein each friction clutch has a disk set, which is arranged between an inner disk carrier and an outer disk carrier and the disk packs are spatially adjacent to one another, the inner disk carrier being connected at least in a rotationally rigid manner to a clutch input, one outer disk each the shaft carrier is connected to a transmission input shaft at least in a torsionally rigid manner, the clutch system having at least two clutch inputs, one clutch input being a clutch input shaft, the other clutch input being an outer disk carrier and the clutch input shaft being operatively connected to an internal combustion engine while on one External disk carrier, a rotor of an electric drive is arranged.
  • a hybrid module for a drive train of a motor vehicle is also known from DE 10 2017 129 873 A1, which has not yet been published, with a housing, a separating clutch, a hydraulic actuating unit which interacts with the separating clutch and is accommodated on the housing, and an electrical machine, a
  • the rotor of the electrical machine is rotatably coupled or can be coupled to a coupling component of the separating clutch
  • the actuating unit has a piston element which is displaceably received relative to the housing and which is displaceably fixed, but relatively, in an axial direction of the separating clutch by means of an actuating bearing is rotatably connected to a pressure element serving for engaging and disengaging the separating clutch, characterized in that the actuating bearing is designed as an axial needle bearing.
  • the prior art always has the disadvantage that, particularly in the case of hybrid modules with a triple clutch, namely with a disconnect clutch and a double clutch, and a coaxially arranged electrical machine, the installation space for installing the triple clutch, in particular in the axial direction, is very limited. As a result, previously known triple clutch designs cannot be used.
  • a hybrid module is to be provided, in which the couplings and their actuations can be integrated in a particularly axial space-saving manner.
  • the return spring and / or the compensation chamber at least partially protrude / protrudes into an axial installation space that lies radially within the separating clutch.
  • the return spring and / or the compensation chamber are arranged radially within the separating clutch.
  • the return spring and / or the compensation chamber are therefore at least partially arranged at the same axial height as the separating clutch.
  • the return spring and / or the compensation chamber can be integrated into the hybrid module in a manner that is virtually neutral in terms of installation space, in particular in the axial direction.
  • the compensating chamber is filled with oil, so that the oil pressure in the compensating chamber applies a force in the axial direction to the actuating piston which can be axially displaced to actuate the separating clutch. This counteracts the force of the actuating force. It is thus avoided in a simple manner that the clutch can be actuated unintentionally by actuating oil remaining in the actuating chamber and pushed radially outward by the centrifugal force caused by the rotation. The oil in the compensation chamber thus counteracts this undesirable force in the axial direction.
  • the clutch can be designed as a double clutch with a first partial clutch and a second partial clutch, the first partial clutch being connectable or connected to a first transmission input shaft and the second partial clutch to a second transmission input shaft for torque transmission.
  • the hybrid module can have a bearing that rotatably supports the rotor carrier in the housing.
  • the return spring and / or the compensation chamber can be arranged radially outside the bearing and / or at least partially protrude into an axial installation space of the bearing. The space available between the separating clutch and the clutch bearing is therefore used to accommodate the actuation system components.
  • first partial clutch, the separating clutch, the return spring, the compensation chamber and / or the bearing are arranged radially nested. This means that the components mentioned are at least partially arranged at the same axial height, only radially offset. This enables a particularly compact design.
  • the actuating cylinder of the separating clutch actuation can be formed by a component that is fixed to the rotor carrier. This has the advantage that no additional component has to be installed in the existing installation space to form the actuating cylinder.
  • the actuation system of the disconnect clutch can therefore be integrated in a particularly space-saving manner, since the already existing components, such as the rotor carrier, are used to form an actuation chamber. As a result, the actuation system can be made axially short.
  • the rotor carrier-fixed component is an integral, i.e. one-material / one-piece material is part of the rotor carrier.
  • the shape of the rotor carrier is therefore used to limit the actuation chamber.
  • the rotor carrier is formed in one part or in several parts. This enables the rotor carrier to be manufactured inexpensively, despite the more complex geometry. For example, it is advantageous if sections of the rotor carrier are welded to one another in order to form the rotor carrier. According to a preferred embodiment, a radial outer diameter and / or a radial inner diameter of the actuating cylinder can be formed by the rotor carrier. This advantageously makes it possible for the actuating piston, which is designed, for example, as a pressure pot, to be displaced axially and radially along the outer diameter and / or the inner diameter. The actuating piston thus runs with the rotation of the actuating cylinder, ie the rotor carrier.
  • the actuating piston can have radially outer and / or radially inner seals, preferably molded on, by means of which a gap between the actuating piston and the actuating cylinder is closed in a sealing manner. This prevents the actuation fluid / hydraulic fluid from escaping from the actuation chamber.
  • the actuation system of the disconnect clutch and / or the clutch is designed as a rotary feedthrough. In this way, the construction space for the actuation system can be kept comparatively small.
  • the hybrid module can have at least one piston ring which is arranged in the radial direction between the housing and the rotor carrier in order to seal an intermediate space between the hydraulic line and the opening.
  • the hydraulic fluid is advantageously reliably guided from the housing into the rotor carrier.
  • the hybrid module has an electric machine that serves as a second drive machine and is arranged coaxially to the hybrid module.
  • the installation space it is advantageous for the installation space to be radial to be used within a rotor of the electric machine and to be as short as possible axially.
  • the invention relates to a hybrid module with a triple clutch.
  • the triple clutch has a disconnect clutch for coupling / uncoupling an internal combustion engine to a drive train / from a drive train and a double clutch with a first partial clutch and a second partial clutch.
  • the double clutch serves to connect / disconnect the hybrid module to a transmission / from a transmission, the double clutch being arranged downstream in the torque flow relative to the disconnect clutch or the hybrid module.
  • the disconnect clutch is actuated by a rotating union that is integrated in a rotor carrier of the hybrid module.
  • the rotor carrier preferably forms an inner diameter and an outer diameter of a cylinder for actuating the separating clutch.
  • a return spring and / or a compensation chamber are / are arranged radially outside a fixed bearing of the separating clutch and radially inside the separating clutch and at least one of the two partial couplings of the double clutch.

  • the hybrid module 1 has a rotor carrier 5, which is designed to initiate a torque generated by a second drive machine, such as an electric machine.
  • the input shaft 4 is switchably connected to the rotor carrier 5 via a disconnect clutch 6.
  • the input shaft 4, and thus the first drive machine, can be decoupled from the drive train 2 (or coupled to the drive train 2) via the disconnect clutch 6.
  • the rotor carrier 5 is connected to an output shaft 8 via a clutch 7.
  • the hybrid module 1 also has a hydraulic actuation system 9 for actuating the separating clutch 6.
  • the actuating system 9 contains an actuating cylinder 10 and an actuating piston 11 which is axially displaceably received in the actuating cylinder 10.
  • the actuating piston 11 interacts with the separating clutch 6 in such a way that the separating clutch 6 adjusts when the actuating piston 11 is axially displaced, i. opened or closed.
  • the separating clutch 6 is designed as a multi-plate clutch / multi-plate clutch.
  • the following direction designations axially, radially and in the circumferential direction relate to a central axis of rotation / longitudinal axis L of the hybrid module 1.
  • An axial direction is therefore a direction along the axis of rotation L
  • a radial direction is a direction perpendicular to the axis of rotation L
  • a circumferential direction To understand direction along a concentric line running around the axis of rotation L.
  • the actuation system 9 is designed as a rotary feedthrough 12. Hydraulic fluid for actuating the disconnect clutch 6 is introduced through a hydraulic line 13 in the housing 3 and through the rotor carrier 5 into an actuation chamber 14.
